Introduction

The Lepidoptera fauna of the Canary Islands, is similar to other oceanic islands, less diverse than of the adjacent continental countries (Morocco, Portugal), but it is still highly interesting due to its many endemic species and subspecies. The Lepidoptera of the islands are considered well-known. Although only few local inhabitants studied these insects for longer periods, the island have been visited by numerous lepidopterists from mainland Europe.

The basic data on Pyraloidea (as “Pyralidae”) of the Canary Islands are eight papers published by the Austrian lepidopterist Hans Rebel between 1892 and 1938 (REBEL, 1892, 1938). Although Pyraloidea are generally considered as belonging to the so-called Microlepidoptera they were not included in the important works on these groups by WALSINGHAM (1908) and KLIMESCH (1977- 1995). In order to remedy this shortcoming ARENBERGER et al. (2001) started a series on papers on Canary Islands Pyraloidea, but only the first part was published. The Scopariinae of the islands were included in a revision of the Macaronesian taxa of this subfamily by NUSS et al. (1997) and GOATER et al. (2005), the latter work also included the Evergestinae. In recent years the works on Pyraloidea of Europe (in a broad sense) by SLAMKA (2006, 2008, 2013) and LERAUT (2012, 2014) have, beside of providing new records of species from the Canary Islands, proved very useful for identifying the species occurring there.

Checklists of - or including - the Pyraloidea of the islands have been published by BÁEZ (latest version 2010), SPEIDEL et al. (last updated 2011) and VIVES MORENO (2014). Some smaller papers dealing with new records of Pyraloidea from the Canary Islands include ASSELBERGS (2009, 2016), GASTÓN et al. (2015) and GASTÓN & VIVES MORENO (2017).

Recent field work in Tenerife and Fuerteventura by the first author has shown that there are still a number of Lepidoptera which have not yet been recorded and identified from these islands. In the present paper we publish information on a number of Pyraloidea new to the Canary Islands, describe a new species of Pima Hulst, 1888, and give comments to a few other taxa. We also include information from material belonging to the Natural History Museum of Denmark. Our material includes a few further taxa of, e. g. Epischnia sp. and Metasia sp., which could not be identified to species, and which will be dealt with later on.

Material and methods

Most specimens have been attracted to artificial light.

Label data is listed in a standardized way under each species, with the islands in alphabetic sequence and the records in chronological order.

The photographs of specimens were taken with Canon EOS700D camera and Soptop SZN 6745 Trinocular zoom microscope and Toup Tek P10500A-E3 / E3ISPM05000KPA-E3 / 5.0MP USB3 camera. Those of the genitalia by using a Soptop CX40T Trinocular biologic microscope and the same camera.

GALLERIINAE

Aphomia sabella (Hampson, 1901) (Fig. 1)

Material examined: TENERIFE, Playa Paraíso, 0-50 m, 1 ♂, 3 ♀ ♀, 1-20-III-2017, P. Falck (PF, MNCN). New to the Canary Islands.

Distribution: North Africa to Middle East; south-eastern Spain (SLAMKA, 2016).

Biology: The larva feeds on Phoenix dactylifera L. and can occasionally be harmful to crops of dates (SLAMKA, 2006: 60-61).

Remarks: The species can be confused with the similar Cathayia insularum (Speidel & Schmitz, 1991), which occurs more commonly in the Canary Islands. The genitalia are figured by, e.g. LERAUT (2014: 78, 83).

PYRALINAE

Aglossa rubralis Hampson, 1900 (Fig. 2)

Material examined: FUERTEVENTURA, Lajares, 50-80 m, 5 ♂♂, 7-27-XI-2017, leg. P. Falck, genitalia slide 2683PF; Corralejo, 0-10 m, 2 ♂♂, 7-27-XI-2017, leg. P. Falck; same data, 5 ♂♂, but 27-II-19-III-2018, leg. P. Falck; Caldereta, 120 m, 1 1, 7-27-XI-2017, leg. P. Falck; same data, 1 1, but 27-II-19-III-2018, leg. P. Falck (all PF).

Description: Male (fig. 5). Wingspan 18-21 mm. Frons and vertex with grey, white-tipped scales, vertex sometime more whitish, neck tufts ochreous brownish. Antenna about 2/3 length of forewing, brown / ochreous ringed, with short cilia (approx. 3/4 diameter of antenna). Labial palpus long (approx.2.5 diameter of the eye) and straight with grey, white-tipped scales, more whitish medially. Thorax and mesothorax greyish; tegulae ochreous brownish. Forewings narrow, generally greyish, ochreous brownish coloured with admixture of black and white scales; costa dark; from the base of costa and vein R a white streak until the post-medial line; the white streak is, from base until the ante-medial line, distinct and then becomes more or less indistinct due to suffusion with dark scales. The white streak is bordered with black scales dorsally; space between vein R and Cubital veins from base until post-medial line ochreous brownish, dividing the weak, grey brown discoidal spot; basal part of dorsum grey; ante-medial line weakly developed; at dorsum a small white spot bordered with blackish scales; post-medial line weakly developed, often interrupted; dorsal third grey with blackish scales; fringes greyish with more dark fringe lines. Hindwing pale greyish; marginal line brown; fringes pale ochreous. Abdomen greyish with suffusion of ochreous brownish scales. Female (fig. 6). Externally similar to male, antennae filiform with shorter cilia (approximately 1/4 diameter of the antenna).

Genitalia ♂(fig. 25): Uncus rounded; gnathos short and narrow, ending in spine-shaped point; tegumen quite short; valva narrow, sacculus sclerotized covered by long spines or hairs, costal arm strong and slightly bifid at apex; juxta relatively large, weakly sclerotized, bi-lobed; vinculum long, V-shaped, strongly sclerotized. Phallus robust, slightly bent at base, with two strongly sclerotized cornuti, one of them slender and pointed, the other broad at the base, tapering towards apex (fig. 25a). Culcita placed on sternit VIII U-shaped with ventrally paired long scale tufts (fig 25b).

Genitalia ♀(fig. 28): Papillae anales small, triangular, posterior and anterior apophyses of same length; tergite VIII short; antrum broad, weakly sclerotized on the edges. Ductus bursae uniformly wide and straight, ± membranous; bursa copulatrix elongate, ovoid with longitudinally sclerotized structures, upper part rounded and covered by fine spines, slug-shaped, ending in ductus seminalis; in the middle part of bursa copulatrix a large, strongly sclerotized blotch.

Diferential diagnosis: P. tricolorella is closely related to P. boisduvaliella (Guenée, 1845) (Europe to Central Asia) and P. aureliae (Leraut, 2014) (North African). P. tricolorella differs from them by external characters of the forewings: it has the white streak conspicuously developed only at the basis of costa until the ante-medial line (fig. 5a), while P. boisduvaliella and P. aureliae have the white streak well developed along the whole length of the wing. The space between vein R and the Cubital veins is generally pale brownish, i.e. paler than the rest of the wing, while P. boisduvaliella and P. aureliae have this space darker coloured. P. leucoloma (Herrich-Schäffer, 1849) (Spain, SE Europe, Turkey) and Pima pempeliella (Zerny, 1936) (Morocco) are quite different by external characters and in the genitalia of both sexes.

The male genitalia of P. tricolorella differ from those of P. boisduvaliella and P. aureliae by the strong cornuti in the phallus: one of them is slender and pointed, and the other is at the base broad, tapering towards to apex (fig. 25a). In P. aureliae (fig. 26) one cornutus is long and very slender and the other short and large, equally tapering into a short point (in P. tricolorella both cornuti are stronger, and the short one has a broader base and a more pointed apex). In P. boisduvaliella the basis of both cornuti are broad, and they are long and pointed (fig. 27).

The female genitalia of P. tricolorella are similar to those of P. boisduvaliella and P. aureliae. P. tricolorella differs from P. boisduvaliella (fig. 29) as follows: the posterior and anterior apophyses are distinctly shorter and also segment VIII is shorter; antrum is narrower, and the sclerotized structures in the bursa copulatrix are different (fig. 28a). The female genitalia of P. tricolorella differ from those of P. aureliae as follows: apophysis posteriores and anteriores are shorter. They differ particularly in the left angle between the ductus bursa and the bursa corpulatrix, which is 170º-180º in P. tricolorella (fig. 28b), about 95º in P. aureliae and about 100º - 110º in P. boisduvaliella (fig. 29a); also, two distinct sclerotized longitudinally structures in the bursa copulatrix are characteristic for P. tricolorella. Bionomy: Early stages and host-plant are unknown. The type series was collected in February and March in semi-deserts at low altitudes. Distribution: So far known only from the Canary Islands, Spain (Fuerteventura and Lanzarote Islands).

Etymology: The species name tricolorella, meaning three-coloured, refers to the colours of the forewings of the new species.

Remark: We could not examine type material of the female of P. aureliae and compared the female genitalia of P. tricolorella with the rather schematic drawing of P. aureliae by LERAUT (2014: 331).

Merulempista saharae Leraut, 2002 (Fig. 7)

Material examined: FUERTEVENTURA, Corralejo, 0-10 m, 3 ♂♂, 2 ♀ ♀, 7-27-XI-2017, leg. P.Falck, genitalia slides ♀2597PF, ♂2598PF; Betancuria, 400 m, 2 ♀♀, 7-27-XI-2017, leg. P. Falck. TENERIFE, El Médano, 0-50 m, 1 ♂, 1-20-III-2017, leg. P. Falck (all PF). New to the Canary Islands.

Distribution: North Africa, Saudi Arabia.

Biology: The early stages and host-plant are unknown.

Remarks: The female genitalia are figured by LERAUT (214: 274). The male genitalia are figured here (figs. 30, 30a).

“Pempelia” laetanella (Lucas, 1937) (Fig. 8)

Material examined. FUERTEVENTURA, Betancuria, 400 m, 1 ♂ 7-27-XI-2017, leg. P. Falck, genitalia slide 2594PF (PF). New to the Canary Islands.

Distribution: Tunisia (LERAUT, 2014: 270).

Biology: The early stages and host-plant are unknown.

Remarks: The generic placement of this species is tentative. LERAUT writes (2014: 270) that he figures the genitalia, but that is not the case. The male genitalia are figured here (figs. 31, 31a).

Epicrocis neftaella (Lucas, 1911) (Fig. 9)

Material examined: FUERTEVENTURA, Caldereta, 120 m, 2 ♂♂, 7-27-XI-2017, leg. P. Falck; Corralejo, 0-10 m, 1 0, 7-27-XI-2017, leg. P. Falck (PF). New to the Canary Islands.

Distribution: North Africa, Cyprus (LERAUT, 2014: 344).

Biology: The larva feeds on Acacia tortilis (Forssk.) Hayne (LERAUT, 2014).

Remarks: The female genitalia are figured by LERAUT (2014: 346).

“Epicrocis” metamelana (Hampson, 1896) (Fig. 10) Salebria aumontella (Lucas, 1911), syn. n.

Material examined: FUERTEVENTURA, 5 ♂♂, Corralejo, 0-10 m, 7-27-XI-2017, leg. P. Falck, genitalia slide 2587PF; Caldereta, 120 m, 1 ♂, 4 ♀♀, 7-27-XI-2017, leg. P. Falck. TENERIFE: El Médano, 0-50 m, 1 ♂, 1-20-III-2017, leg. P. Falck (all PF). New to the Canary Islands.

Distribution: Tunisia (LERAUT, 2014: 344) and Yemen (HAMPSON, 1896: 272). The records by DE PRINS & DE PRINS (2018) from Africa requires confirmation, as the associated photograph shows another species.

Biology: The early stages and host-plant are unknown.

Remarks: Salebria aumontella (Lucas, 1911), which was combined with Epicrocis by LERAUT (2014: 344), is a synonym of Nephopteryx (Salebria) metamelana Hampson, 1896 (in WALSINGHAM & HAMPSON, 1896: 271, pl. 10, fig. 7) (syn. n.). The species is here only provisional combined with the genus Epicrocis, and we are unaware of its correct generic assignment. The female genitalia are figured by LERAUT (2014: 346), the male genitalia are figured here (figs. 32, 32a)

Acrobasis bithynella (Zeller, 1848) (Fig. 11)

Material examined: TENERIFE, Aguamansa, 1050 m, 1 ♂♀, 8-22-XI-2017, leg. P. Falck, genitalia slides ♂ 2604PF and ♀2691PF (PF). New to the Canary Islands.

Distribution: North Africa and southern Europe to southern Russia (SPEIDEL et al., 2011).

Biology: The larva is described in detail by (HUERTAS-DIONISIO, 2009: 71-72). It feeds on Cistus species.

Remarks: A. bithynella is similar to and may be confused with A. obliqua (Zeller, 1847). Adults of both species are rather variable. In the Canary Islands A. bithymella is in average larger and has a more distinct, straight fascia near the base of the forewing, compared to A. obliqua, and the male antennae are more dentate. In the male genitalia A. bithynella has shorter and broader anellus arms, and in the female genitalia A. bithynella has a distinctly sclerotized signum, compared to that of A. obliqua. The genitalia are figured by, e.g. LERAUT (2014: 356, 359). The third Canary Island species of the genus, A. klimeschi Roesler, 1978 is larger and has an oblique transverse line near the base of the forewing, and the male antennae are strongly serrate.

Ancylodes pallens Ragonot, 1887 (Fig. 14)

Bazaria venosella Asselbergs, 2009, syn. n.

Remarks: By checking several specimens of A. pallens from Tenerife and Fuerteventura it became clear that the recently described Bazaria venosella Asselbergs, 2009 from La Palma, Tenerife (and Malta) is a synonym of A. pallens. Both in male and in female genitalia and in general appearance (q. v. ROESLER, 1973) there are no differences. Also, the descriptions of the male antennae are the same: “Sinus flat, segments 3-8 with tiny sclerified thorns...” (ASSELBERGS, 2009), “Hinter dem Basalglied mit zusammengedrükten Schuppen (angedeuteter Sinus) und auf den Gliedern 3-9 mit winzigen Chitinhöckerchen, die nur erkennbar werden...” (ROESLER, 1973) ASSELBERGS (2009: 63) did not compare B. venosella with A. pallens when describing the species.

SPILOMELINAE

Synclera bleusei (Oberthür, 1887) (Fig. 21)

Material examined: FUERTEVENTURA, Corralejo, 0-10 m, 1 ♀, 7-27-XI-2017, leg. P. Falck; Las Parcelas, 70 m, 1 ♀, 7-27-XI-2017, leg. P. Falck (all PF). TENERIFE, Los Cristianos, 1 ♂, 29-XII-2003, leg. O. Karsholt (ZMUC); Playa Paraíso, 0-50 m, 1 ♂, 1-20-III-2017, leg. P. Falck (PF).

Distribution: North Africa to Iran and Afghanistan (SLAMKA, 2013: 117).

Biology: The early stages are described in detail by CHRÉTIEN (1917: 448-449). The larva feeds on Daemia cordata R.Br. (now: Pergularia tomentosa L.) (Asclepiadaceae). Also, Suaeda vera (Forssk. ex. J. F. Gmel.) is listed as a host-plant (CATANIA, 2018: 174).

Remarks: S. bleusei is not listed from the Canary Islands by VIVES MORENO (2014). It was, however, already recorded from Tenerife by REBEL (1906: 37) as “Nymphula bleusei”, and from Fuerteventura by MUUS (2011). It is unclear to us if the record from the Canary Islands as Synclera traducalis (Zeller, 1857) by SLAMKA (2013: 116) and VIVES MORENO (2014: 423) refers S. bleusei, and the occurrence of the former in these islands requires confirmation. Recently the species was recorded in this journal from Malta under the name of Bocchoris bleusei (CATANIA, 2018), who also refers to the record from Tenerife published by REBEL (1906)

Duponchelia caidalis Oberthür, 1888 (Fig. 22)

Material examined: FUERTEVENTURA, Las Parcelas, 70 m, 4 ♂♂, 1 ♀, 7-27-XI-2017, leg. P. Falck, genitalia slide 2625PF; same data, 1 HEM, but 27-II-19-III-2018, leg. P. Falck (all PF). New to the Canary Islands.

Material examined: FUERTEVENTURA, Las Parcelas, 70 m, 2 ♂♂, 1 ♀, 27-II-19-III-2018, leg. P. Falck, genitalia slide 2700PF (PF). New to the Canary Islands.

Distribution: North Africa and western Mediterranean countries (SLAMKA, 2008: 24).

Biology: The larva feeds on Salicornia (SCHOUTEN, 1992: 224).

Remarks: The genitalia are figured by, e. g. SLAMKA (2008: 164-165, 193).

Euchromius ramburiellus (Duponchel, 1836) (Fig. 24)

Material examined: FUERTEVENTURA, Corralejo, 0-10 m, 1 ♀, 7-27-XI-2017, leg. P. Falck, genitalia slide 2635PF; TENERIFE, El Médano, 0-50 m, 1 ♂, 2 ♀ ♀, 1-20-III-2017, leg. P. Falck genitalia slide 2636PF (all PF).

Distribution: North Africa, southern Europe, Turkey, Middle East and Arabia to Central Asia (SLAMKA: 2008: 24).

Biology: The larva is described by CHRÉTIEN (1917: 414). It feeds on dead leaves of Frankenia pallida (Boiss.) (Frankeniaceae). It is also reported feeding on dead leaves of Cirsium, Hieracium and Cichorium (Astraceae) (SCHOUTEN, 1992: 228).

Remarks: This species is dealt with here because it was recorded from the Canary Islands

Biology: The larva is described by CHRÉTIEN (1917: 414). It feeds on dead leaves of Frankenia pallida (Boiss.) (Frankeniaceae). It is also reported feeding on dead leaves of Cirsium, Hieracium and Cichorium (Astraceae) (SCHOUTEN, 1992: 228).

Remarks: This species is dealt with here because it was recorded from the Canary Islands (Fuerteventura) by SCHOUTEN (1992: 227-228), but not included from there by VIVES MORENO (2014). The genitalia are figured by, e. g. SLAMKA (2008: 165, 193).

Discussion

VIVES MORENO (2014) listed 128 species of Pyraloidea from the Canary Islands, and the additions published by GASTÓN et al. (2015), ASSELBERGS (2016) and VIVES MORENO & GASTÓN (2017) raised the number to 132 species. In the present paper, we add 22 species, synonymize one species and question the occurrence of two species in the Canary Islands, bringing the number of Pyraloidea recorded from these islands up to 151 species.

The fact that a few weeks of collecting in the Canary Islands by the first author, and the study of the rather small collection of Canary Islands Pyraloidea in one museum (ZMUC) have resulted in a 15% increase in the number of recorded species questions our postulate in the introduction of this paper that “The Lepidoptera of the islands are considered well known”. We find it more likely that there are still many species to be discovered and recorded from the Canary Islands.

Acknowledgments

The authors are grateful to Dr. Antonio Vives, Madrid, Spain for translating the abstract into Spanish, for editing our manuscript, and for his kind help with obtaining permission to collect Lepidoptera in the Canary Islands into the Scientific Project of SHILAP, and to Dr. Joël Minet, Muséum National d’Histoire Naturelle, Paris, France for photographs of the holotype of Pima aureliae. Dr. Colin W. Plant, Bishops Stortford, England, kindly corrected the English language andcommented on the manuscript.
