Tineoidea (Meessiidae, Tineidae) and Glyphipterigidae: Acrolepiinae from the Canary Islands, Spain (Insecta: Lepidoptera)

Based on recent field work and examination of specimens of the families Meessiidae and Tineidae (Tineoidea) and the subfamily Acrolepiinae (Glyphipterigidae) we record the following three species as new to the Canary Islands: Xystrologa grenadella (Walsingham, 1897) (Meessiidae), Nemapogon granella (Linnaeus, 1758), and Tinea translucens Meyrick, 1917 (Tineidae). Haplotinea insectella (Fabricius, 1794) is deleted from the Canary Islands list. We also describe one hitherto undescribed species: Neurothaumasia betancuriacola Gaedike & Falck, sp. n.. For a further 31 species, hitherto known from the Canary Islands, we established first records for several islands. A checklist of the 50 taxa now known from the Canary Islands is presented, with indications of the sources of records.

Based on recent examination of specimens from the above mentioned families by the first author and field work by the second author, we are now able to record four species as new to the Canary Islands: Xystrologa grenadella (Walsingham, 1897) (Meessiidae), Nemapogon granella (Linnaeus, 1758), Tinea translucens Meyrick, 1917 (Tineidae) and a previously undescribed species of the genus Neurothaumasia.
The examined material contains several new records for separate islands and these records are marked in bold in a checklist containing all hitherto known 50 taxa (Meessiidae; Tineidae; Acrolepiinae) from the Canary Islands.
Haplotinea insectella (Fabricius, 1794) was hitherto recorded as member of the Canarian fauna, following WALSINGHAM (1908) in KLIMESCH (1980), but it was a misinterpretation of Setomorpha rutella (Zeller, 1852) in WALSINGHAM (1908) under the name Setomorpha insectella F. sensu Walsingham, 1908.The species is up to now not recorded from the Canary Islands (A.Vives, pers. comm.), the species is to be deleted from the Canary Islands list.Description (Figs 1-2): Wingspan 14-16 mm; head brush white, laterally and below palpi light brown; scape creamy, with pecten, flagellum brown-grey; labial palpus short, outside darker than inside, second segment apically with some bristles; thorax and tegulae white, basally light brown, sometimes thorax brown; forewing brown with clearly defined white pattern.White are: a stripe on dorsum from nearly the base to & of the length, last part bent; a stripe from middle of base oblique to costa before >, basally thin, last half broader; sometimes the stripe fused with the stripe on dorsum, not reaching base (fig.2), a large lens-shaped patch on costa at 2/3 and nearly the whole area around brown-tipped apex.Fringe white, somewhat creamy; hindwing grey.

Abbreviations
Male genitalia (Figs 3-5): Uncus apically incised, each lobe divided into a somewhat longer and broader inner part and a shorter and narrower outer part; gnathos arms curved, basal half narrower than apical half, apically forked; valva in first third parallel, then continuously narrower to rounded tip; phallus as long as valva, basally rounded, first third narrowest, before > bulged, apical half narrower to pointed tip.Female genitalia (Fig. 6): Dorsal branches of anterior apophyses ending in a more strongly sclerotized band, ventral branches connected by narrow square band, edge with minute bristles.
Diagnosis: Superficially distinguishable from N. ragusaella (Wocke, 1889) by the characteristic white pattern on forewing.The white parts are stripes from nearly the base along dorsum and from the middle of base oblique to costa, a lens-shaped patch on costa and the area around brown-tipped apex, while ragusaella is characterized by having on white groundcolor a brown base, a brown stripe at > from costa to dorsum, sometimes interrupted in the middle and a stripe on costa before apex, obliquely directed to dorsum at beginning of fringe.The genitalia structures are similar to that taxon, but the shape of uncus lobes and the apically forked gnathos arms are different.The shape of valva varies somewhat, depending on the pressure applied during preparation.The structure of female genitalia shows no clear differences.
Molecular diagnosis: Two specimens of N. betancuriacola were sequenced, resulting in 658 bp, full-length DNA barcode fragments for one specimen, and fragments of 615 bp for the other specimen.The nearest neighbor to N. betancuriacola is N. ragusaella with a 3.8% divergence.The intraspecific variation in the barcode fragment in the sampled N. betancuriacola is 0.0%.The results support the status of N. betancuriacola as a distinct species.
First records were checked by the authors and marked in bold.The occurrence in Tenerife is doubtful and has to be confirmed by recent records.KLIMESCH (1980) did not himself examine specimens, but referred to WALSINGHAM (1908).Some of the specimens recorded in the latter paper were examined by ROBINSON (1979): they belong to T. dubiella Stainton, 1859 and T. murariella Staudinger, 1859.
