The types of Scathophaga albidohirta (Becker, 1907) and Scathophaga infumata (Becker, 1907) (Diptera, Scathophagidae) are studied. Lectotype for S. albidohirta is designated. Redescriptions are given and illustrations of male terminalia of both species are presented for the first time. РЕЗЮМЕ. Изучены номенклатурные типы Scathophaga albidohirta (Becker, 1907) и Scathophaga infumata (Becker, 1907) (Diptera, Scathophagidae). Обозначен лектотип для S. albidohirta. Даны переописания и впервые приводятся иллюстрации терминалий самцов для обоих видов.
Scatophaga albidohirta Becker, 1907: 254. Lectotype , 'Kurlyk' [CHINA: lake Hurleg Hu (37.28њN, 96.89њE)], in ZISP [see designation below].

Introduction
Both species discussed below were described by Theodor Becker from the materials collected during two expeditions to China organized by Imperial Russian Geographical Society. Detailed reports of the expedition to Central Asia under the direction of V.I. Roborowsky in 18931895 and expedition to Mongolia and Kum under the direction of P.K. Kozlov were published by P.K. Kozlov [Kozlov, 1899, 1905].

Taxonomic part
Scathophaga albidohirta (Becker, 1907) Figs 15.

The species was described from 8 specimens from China; male being described more completely. 7 specimens, 2 males and 5 females, are kept in the collection of the Zoological Institute St.-Petersburg (E. Nartshuk, personal communication). We examined 4 of them: both males and 2 females. Information about the rest specimens was got from E. Nartchuk. with label 'Курлык, Баингол вост. Цайдамъ. Роб[оровский] Козлов 21.V.[18]95' [Kurlyk, western Baingol, Caidam, 21.V.1895, coll. Roborowsky et Kozlov] corresponds to original description and is labelled and designated herewith as lectotype of Scathophaga albidohirta. Lectotype is pinned, one of middle legs glued to geographical label and without tarsomers 24, the other middle leg lost, tibia and tarsi of left hind leg lost, as well as tarsomers 24 of right hind leg; abdomen cut and mounted in tube with glycerol on the same pin with the specimen. All the rest specimens of the type seria (syntypes) are labelled as paralectotypes of Scatho-phaga albidohirta. Among them: with the label 'р[ека] Орогын Сартын ю[жнее] Наньшаня[,] Гоби[,] Роб[оровский] Козлов 3 20.V.[18]95' (our study) and 2 with labels 'оз. Иче - р. Орогын с. Цайдам ц. Гоби РобКозлов 3 VII 95' and 'р. Орогын Сыртын ю. Наньшаня Гоби РобКозлов 320 VII 95' (communication by E.

Nartchuk) have dark rings on tarsomers and belong to S. albidohirta (see redescription below). with the label as in holotype, was determined by us as Scathophaga mihalyii (Рifner, 1975). with the label 'Кара Тюбе, на зап[ад]. от Хами, Гоби. Роб[оровский] Козлов 5.IX.[18]95' and with the label 'р. Бомын (Ичегын) св. Цайдам Гоби РобКозлов VI 95' have completely yellow tarsi (without dark rings) and surely dont belong to S. albidohirta. However it is impossible to determine them to species from females and each of them were signed as Scathophaga sp. The eighth syntype (labelled as paralectotype of S. albidohirta also) is kept now in the collection of the Museum fьr Naturkunde der Humboldt-Universitдt, Berlin. It is with dark rings on tarsomers and it belongs to S. albidohirta. It is labelled 'оз. Иче - р. Орогын с. Цайдам ц. Гоби РобКозлов 3 VII 95' and two labels handwritten by Th. Becker: 'Gobi, Asien VII. 51896', 'albidihirta Beck.' (personal communication from Dr. J. Ziegler). REDESCRIPTION. Length of body 6.16.7 mm. Length of wing 5.85.9 mm. Male. Head. Frons matt, yellow in lower part and black in upper part. Eye orbit, ocellar triangle and

Antenna black. Postpedicel with slightly acute dorsoapical corner, approximately 2 times as long as wide; arista brownish to blackish, bare. Clypeus and prementum black.

Proepisternum, proepimeron, anepisternum and katepisternum with pale hairs. Anepimeron bare. Anepisternum with 23 long setae near posterior margin. Katepisternum with 1 seta in posterodorsal corner. Scutellum with 2 pairs of strong setae and with hairs laterally. Legs. Femora of all legs greyish microtrichose, black in basal 4/5 and yellow apically.
