Dexia maritima Kolomiets, 1970

Dexia maritima Kolomiets, 1970: 70 . — Mesnil 1980: 45 (redescription). — Herting 1984: 143 (catalog). — Herting & Dely-Draskovits 1993: 366 (catalog). — Richter 2004: 355 (key). — Chao et al. 2009: 576 (fauna).

Diagnosis. Female. Frons more than 1/3 head width; gena about 3/4 as wide as eye height; antenna yellow, 1st flagellomere about twice as long as pedicel; thoracic dorsum with 4 very narrow dark longitudinal vittae; 2 presutural and 2 postsutural acrostichal setae; 2-3 presutural and 3 postsutural dorsocentral setae; 2 intra-alar setae; 2 katepisternal setae; tegula and basicosta yellowish brown; lower calypters with long fringe; legs reddish yellow. Body length of female: 9 mm.

Type material. Holotype female of Dexia (Dexillia) maritima Kolomiets, Gologin, Primorskyi, Far East Russia, 4.viii.1965, N.G. Kolomiets ( ZIN) (not examined).

Distribution.? China (Beijing, Hebei, Gansu, Inner Mongolia, Qinghai, Sichuan, Xizang, Yunnan), Russia (Far East).

Remarks. Kolomiets (1970) described this species based on a female from Far East Russia and Mesnil (1980) redescribed it in detail. We were unable to look at the type or other specimens of this speices. According to the original description and Mesnil (1980), this species has very narrow longitudinal vittae on the scutum and the lower calypter has a long fringe. In these characters this species appears to be similar to European species D. vacua . The male of this species is unknown. Chao et al. (2009: 576) recorded this species from many localities in China, but their redescription of it does not fit well with that by Mesnil (1980) and their identification needs confirmation.
