Abstract

Gelechiaomelkoi sp. nov. is described from the Ukok plateau and South Chuisky ridge in the Altai Mountains of Russia. The adult of the new species, including its male genitalia, is illustrated and compared with species most similar in morphology and DNA barcodes—G.sororculella (Hübner, 1817) and G.jakovlevi Krulikovsky, 1905 from the Palaearctic region, as well as G.mandella Busck, 1904 from Canada. This last species is redescribed based on adult specimens, including the genitalia of both sexes, and a lectotype is designated. Gelechiasirotina Omelko, 1986 is recorded from the Altai Republic for the first time. An updated list of six species of Gelechia from the Altai Mountains of Russia is given. Dorsal habitus photographs of all species are provided. The male genitalia of the lectotype of G.jakovlevi is illustrated for the first time.

Highlights

During a collecting trip to the Altai Mountains in 1995, the first author collected a short series of uniformly greyish-black Gelechiidae
A lectotype is designated for G. mandella, which is redescribed based on additional material, with male and female genitalia illustrated for the first time
We provide an updated list of Gelechia species known from the Altai Republic of Russia, with additional distributional information including the first record of G. sirotina Omelko, 1986

Summary

Introduction

During a collecting trip to the Altai Mountains in 1995, the first author collected a short series of uniformly greyish-black Gelechiidae. DNA barcoding of one of these specimens indicated that specimens from the Ukok plateau represented a new species (Huemer et al 2017), with 5.94% minimum distance to the nearest Palaearctic species, G. sororculella, and 2.88% minimum distance to the nearest Nearctic species, G. mandella Busck, 1904. This last species was described from British Columbia, Canada, but it had since not been treated in the taxonomic literature. We provide an updated list of Gelechia species known from the Altai Republic of Russia, with additional distributional information including the first record of G. sirotina Omelko, 1986
