The species of Aphodius Illiger subgenus Aphodaulacus W.Koshantschikov from Middle Asia and China related to A. turkestanicus Heyden are reviewed. Two new species are described: A. kizeritskyi, sp. n. and A. grumi, sp. n.

Study of the Aphodius Illiger material from the collection of Zoological Institute RAN (ZIN) allowed to find two previously unknown species of subgenus Aphodaulacus W. Koshantschikov, closely related to A. turkestanicus Heyden, the type species of the subgenus. A review of 4 species of the group turkestanicus, distributed in Middle Asia and China, is given below.

Type specimens of the new species are supplied with red labels "HOLOTYPUS [or PARATYPUS] Aphodius [name of a species] A. Frolov det. 2000". Examined material, including type specimens, is deposited in ZIN. Author's notes are in square brackets. 

Aphodius (Aphodaulacus) kizeritskyi Frolov, sp. n. (Figs. 1, 6, 8).

Material. Holotype: male labeled "Zakaspijskaya obl. Duzolum' [Duzu-Оlum: south-western Turkmenistan, Sumbart River, ca. 10 km upstream Sharloun] 21.X.1902 [in Cyrillic letters]", "k. Yakovleva [collection of Yakovlev, in Cyrillic letters]"; paratypes, females: one labeled "Transcaspien C.O. Anger [in Latin letters] Imam Baba [southeastern Turkmenistan] 3.XI.[18]99 / peski [sands] [in Cyrillic letters]", "k. Yakovleva [in Cyrillic letters]", and another labeled "Iolotan' [southeastern Turkmenistan] 12.XI.[19]12 V. Kizeritskiy [leg.] [in Cyrillic letters]". In addition to the type material, a damaged male specimen without head was examined; this specimen was originally mounted on the same pin with female paratype from vicinity of Imam-Baba.

Description. Male (holotype). Head shiny, brown on disc, pale brown on anterior part and sides of clypeus, sparsely regularly punctate (punctures separated by 3--5 times a puncture diameter). Clypeus wide, feebly sinuate on anterior margin, widely rounded at sides. Genae acute-angled, distinctly separated from lateral margins of clypeus, strongly protruding past eyes, with a dense wisp of long setae. Head without frontal tubercles and frontoclypeal suture. Diameter of eye in ventral view slightly smaller than minimum interval between eye and gula.

Pronotum shiny, brown on disc, pale brown on sides. Anterior margin and base not bordered, lateral margins with fine border. Disc sparsely regularly punctate (punctures separated by 4--6 times a puncture diameter). Posterior angles of pronotum obtuse, sides with short yellowish setae; pleural setae, visible from above, relatively long and dense (Fig. 1).

Scutellum narrowly triangular, shiny, brown, impunctate and smooth in apical part.

Elytra pale brown, with brown maculae on interstices 3--8, without humeral denticles. Elytral interstices feebly convex, densely punctate and densely pubescent with relatively long yellowish setae. Striae fine and shallow. Underside of body and legs pale brown.

Spur of anterior tibia acute and slightly curved downward, reaches middle of 2nd tarsal segment. Lower spur of middle tibia shorter than half the length of upper spur, its apex truncate. First segment of posterior tarsus slightly longer than the upper spur of tibia and nearly as long as 3 following segments together. Apical setae of posterior tibiae of unequal length. Disc of metasternum slightly concave, with sparse setae on perimeter. Apices of parameres slender and acute, slightly curved upward (Fig. 8). Body length 6.0 mm.

Female can be separated from male by narrower and more densely punctate pronotum, shorter and sparser setae on elytral intervals, and acute lower spur of middle tibia.

Variability. It is impossible to adequately judge variability of the species on the basis of the examined material. Examined specimens slightly differ in pattern of dark maculae on elytra. Damaged male, not included in the type series, differs from the holotype in the slightly densely punctate pronotum and longer upper spur of posterior tibia, which is slightly longer than first segment of tarsus. Body length of paratypes 5.0--5.5 mm.

Diagnosis. This species can be easily separated from other species of the group in question by the shape of parameres and relatively dense pubescence of the entire elytra in females (Fig. 6) (except, possibly, for A. grumi sp. n., female of which is unknown). From A. turkestanicus it can also be separated by the pubescent sides of pronotum.

Distribution. The species is found in two distant localities in Krasnovodsk and Mary provinces of Turkmenistan. Probably, the species is widely distributed in southern Kara Kum Desert, reaching the inner regions of the desert along river banks.

Aphodius (Aphodaulacus) turkestanicus Heyden, 1881 (Figs 2, 7, 9).

Material. Kazakhstan: Muyun Kym Desert, VII.1908, 7 spms., and VI.1908, 3 spms. (Fisher); Akmolinsk, 20 spms. (Kricheldorff); Malye Barsuki Desert, 5.VI.1931, 1 spms. (Luppova). Uzbekistan: Zhamansai, 140 km NW of Shafrikan, 27.IX.1967, 1 spms. (Falkovich). China: Xinjiang Uygur Autonomous Region, Mu-lei-khe River [on labels: Muli-khe; ca. 200 km E of Urumqi, northern slope of Bogda Shan Mts.], 16.IX.1889, 48 spms.; a river SE of Mu-lei-khe, 16.IX.1889, 62 spms.; Ulan-Usu River [on labels: Ulan-su; ca. 250 km E of Urumqi], 1.X.1889, 5 spms. (Grum-Grzhimailo).

Diagnosis. This species can be separated from other species of the group in question by the not pubescent sides of pronotum (Fig. 2) and the shape of parameres (Fig. 9). From A. kizeritskyi sp. n. it differs also in the weakly visible pubescence on disc of elytra in females (Fig. 7).

Distribution. According to Nikolajev (1987: 117) the species is distributed throughout Middle Asia up to Zaissan depression in the North-East. The species is reported from China (Chinese Tien Shan) for the first time. 

Aphodius (Aphodaulacus) ignobilis Reitter, 1887 (Figs. 3, 4, 11).

Material. China: Qinghai Province, southern coast of the Lake Qinghai Hu (Kuku-Nor), middle August 1901, 6 spms. (Kozlov); Babo-khe and Khyi-khe rivers [on labels: Babo-Kho and Khy-Kho; Hei-he: ca. 150 km N of the Lake Qinghai Hu], 13.VIII.1890, 7 spms. (Grum-Grzhimailo); Gansu Province, VIII.1872, 1 spms. (Przhewalsky). Also, in the collection of ZIN two specimens labeled "Amdo 1886 G.Potanin" and "Amdo 1884 Przhevalsky" are deposited; the last specimen bears also a hand-written label of unknown author "A. ignobilis Rtt. type", but it is not the nomenclatorial type.

Diagnosis. The species can be easily separated from other species of the group in question by the pubescent clypeus in both sexes (Fig. 4) and the shape of parameres (Fig. 11).

Distribution. The species is endemic to Tibet. Balthasar (1964: 211) reported this species from "Buchara, Buda-Gebirge" [it must be Burchan-Buddai Range in northeastern Tibet, wherefrom the species was described] and from “Turkestan”. Probably, it was reported from "Turkestan" basing on the misidentified specimens of A. turkestanicus or mislabeled material, as also supposed by Nikolajev (1987: 117). 

Aphodius (Aphodaulacus) grumi Frolov, sp. n. (Figs 5, 10).

Material. Holotype: male labeled "Babo-Kho i Khy-kho [for the localization of the toponyms, see above] do [before] 13.VIII.[18]90 Gr.Grzhimailo [leg.] 1902 [in Cyrillic letters]", "Aphodius ignobilis Rtt. W.Koshantschikov det.".

Description. Male (holotype). Head shiny, pale brown with faint reddish tint; elytra yellowish brown without reddish tint, with indistinct darker maculae on intervals 3--7; sclerites semitransparent (probably the specimen is incompletely melanized).

Head densely regularly punctate (punctures separated by 1--2 times a puncture diameter). Clypeus wide, spade-shaped, nearly not sinuate on anterior margin, but with strongly incrassate border; its anterior angles widely rounded. Genae acute-angled, distinctly separated from lateral margins of clypeus, strongly protruding past eyes, with a dense wisp of long setae. Head not tuberculate, frontoclypeal suture distinct. Diameter of eye in ventral view slightly smaller than minimum interval between eye and gula.

Anterior margin and base of pronotum not bordered, lateral margins slightly flattened and distinctly bordered. Disc relatively densely regularly punctate (punctures separated by 1--2 times a puncture diameter). Posterior angles of pronotum obtuse, sides and base with short yellowish setae; pleural setae, visible from above, relatively short and sparse (Fig. 5).

Scutellum narrowly triangular, shiny, brown, impunctate and smooth in apical part.

Elytra without humeral denticles. Elytral intervals feebly convex, densely punctate and densely pubescent with relatively long yellowish setae. Striae fine and shallow.

Spur of anterior tibia acute and slightly curved downward and outward, reaching apex of 1st  tarsal segment. Lower spur of middle tibia 1/3 the length of upper spur, its apex obliquely truncate. First segment of posterior tarsus as long as upper spur of tibia and slightly shorter than 3 following segments together. Apical setae of posterior tibia of unequal length. Disc of metasternum with long dense setae on edge. Apices of parameres acute and curved downward (Fig. 10). Body length 9.0 mm.

Female unknown.

Diagnosis. This species can be separated from other species of the group in question by its larger size, curved downward apices of parameres, and pubescent base of pronotum.

Etymology. The species is named in honor of G.E. Grum-Grzhimailo, a famous researcher of Middle and Central Asia, who collected the type specimen.
