Tinagma armeniacum Gaedike, sp. n. and a list of Douglasiidae of the Caucasus region (Lepidoptera: Douglasiidae)

Tinagma armeniacum Gaedike, sp. n. y una lista de Douglasiidae de la región del Cáucaso (Lepidoptera: Douglasiidae)

Introduction

The kindness of my colleagues O. Karsholt, H. Roweck and N. Savenkov enabled me to study interesting material from Armenia, collected last year. As a result, it was possible to detect a new species together with some new country records. The description of this new species is presented below, together with a list of the hitherto known members of the family in the Caucasus region.

In the entire Palaearctic region 22 species of this family are now known, which is, according to REGIER et al. (2014) a member of an unassigned superfamily between Gracillarioidea and Hyblaeoidea.

Larvae of Douglasiidae are feeders in leaves or reproductive parts of their host plants (Boraginacae, Hydrophyllaceae, Rosaceae, Lamiaceae).

Adults can be collected at light and some species have been observed flying at dusk, in the morning and during the daytime.

LT: Jagry, Nakhichevan ASSR, Azerbaijan

Material examined: Azerbaijan (BUDASHKIN, 2003); Iran, Derbend, 25km N of Tehran, 2000 m, 15 ♂, 7-15-VI-1963; 28-30-V-1963; leg. F. Kasy & E. Vartian (NMW; SDEI): New to the country and first record beside type series.

The other records from Iran (Keredj (NRM) and NW-Iran, 30 km S of Rizayeh (SMNK)) need checking, but they seem to also belong to this subspecies.

Tinagma armeniacum Gaedike, sp. n. (Figs 1-2)

Material examined: Holotype ♂, Armenia, prov. Ararat, Urtsadzor, Caucasus Wildlife reserve, Eco Lodge, 1250 m, 39º56’58”N 44º53’14”E, 22-30-V-2019, O. Karsholt, H. Roweck & N. Savenkov leg. Genitalia slide 9927RG (ZMUC). Paratypes: 1 ♂, with the same collection data, Genitalia slide 9928RG (SDEI); Vedi Urtsadzor, CWR Eco Lodge, 1250 m, 1 ♂, 20-30-V-2019, [leg.] H. Roweck & N. Savenkov. Genitalia slide 9780RG (coll. Roweck).

Description: Wingspan 10-11mm; head dark grey, scales with white tips; labial palpus whitish colored, apical segment on outside somewhat darker; antenna dark grey, underside lighter, thorax, tegulae and forewing with same coloration as the head; forewing on dorsum at beginning of fringe with white wedge-shaped patch, reaching cell; hindwing grey. One paratype (fig. 2) with lighter grey coloration.

Genitalia male (Fig. 3): Tegumen band-shaped, without separate uncus; anellus basally square, apically with two long thin processes; vinculum in the middle somewhat broader than laterally; valva more or less square, at ventral edge folded, costal arm short, ending rounded, on inside bristled and with minute thorns, apical edge below costal arm concave, basal edge more or less straight, phallus more than twice as long as valva, slightly curved, basal quarter edged, with minute sclerotization on inside.

Genitalia female: Unknown.

Diagnosis: Superficially similar to T. anchusella (Benander, 1936), but the coloration is clearly darker, and the white patch larger. In the genitalia the shape of valva is different: costal arm in armeniacum short, while anchusella with longer and narrower costal arm.

Biology: Unknown.

Etymology: The species is named after the country of the type locality
