Anthomyza decolorata Roháček, 2009 View in CoL

Material examined. RUSSIA: Fൺඋ Eൺඌඍ: o. Kunashir, okr. vlk. Mendeleeva, 4.vii.1985, 1 J, 8.vii.1985, 1 ♀, 23.vii.1985, 1 ♀, 29.vii.1985,

1 ♀; Tretʼyakovo, 21.vii.1985, 1 ♀, all S. Churkin leg. (all ZMUM, 1 J 1 ♀ genit. prep.).

Remarks. Anthomyza decolorata belongs to the A. macra group (RඈIJගඹൾκ 2009) and was found to be the closest relative of the Nearctic A. oblonga Roháček & Barber, 2016 by RඈIJගඹൾκ & Bൺඋൻൾඋ (2016: 377–379). It is distinguished by its bicolourous (largely yellow) head and thorax and strikingly dorsomedially depigmented preabdominal terga, apart from a distinctive gonostylus and unusually extensive sclerotization of the anterior part of the female genital chamber (RඈIJගඹൾκ 2009: figs 36, 38). Distribution. The species is known only from the Far East of Russia. It was described from Kamchatka and Kunashir I. (RඈIJගඹൾκ 2009). Additional records from Kunashir I. indicate that it could be a relatively frequent species on this island.
