E–mail: [email protected] Received 28 January 2021 │ Accepted by V. Pešić: 22 February 2021 │ Published online 24 February 2021. Abstract A checklist and distribution of the taxa of the Dichagyris subgenus Albocosta, with the description of three new species (D (A.) musichuana sp. n., D (A.) ochrocosta sp. n., D (A.) antevolans sp. n.) and two new subspecies (D (A.) lasciva pamirpsychra ssp. n., D (A.) triangularis sinangularis ssp. n.) are given. Key words: Asia, taxonomy, Noctuidae. Introduction The genus Albocosta (= Pseudochropleura Beck, 1992, nomen nudum) was erected by Fibiger & Lafontaine in 1997 for a group of species, characterised by a typical forewing pattern, in which the base colour is reddish brown, whereas the costa widely whitish, yellowish or ochreous. Most of the species associated to this newly established genus, originally had been described as Agrotis Ochsenheimer, 1816, while a few of them as Chersotis Boisduval, 1840, Ochropleura Hübner, [1821] 1816 or Rhyacia Hübner, [1821] 1816. Studying the male and female genitalia structures, and comparing the genitalia configuration with those of the genus Dichagyris Lederer, 1857, author did not find any significant differences that would justify the classification of these species as a separate genus. Thus Albocosta is accepted here as a subgenus of Dichagyris. In the male genitalia, the capsule does not indicates conspicuous differences among the each taxa, while the vesica is long, tubular or more ample, coiled. In the female genitalia, most of the taxa have bifurcate, long, sack-like bursa, while in a few ones the appendix bursae is much shorter, ovoid. The genus Basistriga Fibiger & Lafontaine, 1997 ((Noct. Eur. 3: 125; TS: Noctua flammatra (Denis & Schiffermüller, 1775)) is accepted here also as a subgenus of Dichagyris, but not as a synonym of Albocosta. The checklist and distribution of the taxa of the subgenus Albocosta, including the three new species and two new subspecies being described in this article, are given here.
