Redescription. Length 5.0–6.0 mm, oblong, moderately convex, shiny, glabrous. Head, pronotum, and scutellum black; elytra dirty yellow with suture and sides shadowy piceous; legs reddish brown; antennal club piceous. Head with epistome gibbous, sparsely, irregularly, subrugosely punctate, punctures distally confusedly coarser; clypeus feebly sinuate at middle, round at sides, thinly bordered, edge feebly upturned, glabrous; genae widely round, setose, feebly protruding from the eyes; front sparsely and somewhat irregularly punctate. Pronotum transverse, moderately convex; dually punctate, large punctures somewhat denser on sides, 6–7 times larger than small punctures, latter almost regularly scattered throughout, more superficial on disc; lateral margin feebly round, rather thickly bordered, edge setose; hind angles widely truncate, truncation weakly sinuate inward, base entirely thinly bordered. Scutellum triangular, elongate, flat, with few sparse punctures on basal half. Elytra elongate, feebly widened apically, setose at shoulder, rather deeply striate; striae superficially punctate, subcrenulate; interstriae almost flat, sparsely and finely punctate. Metatibiae superior spur as long as first metatarsomere; latter as long as following 3 metatarsomeres combined. Male: epistome anteriorly with curve, transverse carina, relatively more sparsely and less coarsely punctate; frontal suture with a small central tubercle; disc of pronotum without large punctures; protibiae spur feebly hooked inwardly at apex; aedeagus Figs. 4–5 . Female: epistome anteriorly without transverse carina, more densely and coarsely punctate; frontal suture gibbous at middle; disc of pronotum with some large punctures; protibiae spur straight.

Distribution. China, Kazakhstan, Mongolia, Russia, Siberia, Taiwan, Turkmenistan.

Remarks. A female of Aphodius costalis Gebler, 1848 , lectotype here designated, in Muséum national d’Histoire naturelle, Paris, France, bears the following labels: 1) white, handwritten: costalis /Gebl. Sibiria; 2) green, printed: Museum Paris/ex coll./R. Oberthür; 3) red, printed: Aphodius costalis Gebler, 1848 , Lectotypus, M. & G. Dellacasa des., 2001. We deem that this specimen, found in Oberthür collection, came from Gebler’s collection that, via G.V. Mniszech and R. Oberthür (see Sachtleben 1961: 500) should be in the MNHN. The species seems to be very rare. Gebler adopted the name Aphodius costalis of C. Mannerheim (in litteris), reproduced Mannerheim’s note: “Eine neue, noch unbescriebene Art, die ich von meheren Jaren aus der kirgisischen Steppe erheilt und an Gr. Dejean sendete, der sich auch für neu erkannte. M.”. Schmidt (1922: 21) indicated “Westsibirie”; Balthasar (1964: 286) added “sudlichen Ural”; Nikolajev (1987: 118) recorded the species from Kazakhstan.

A female of Aphodius sibiricus Harold, 1863 (junior synonym of A. costalis ), lectotype here designated, in Muséum national d’Histoire naturelle, Paris, France, bears the following labels: 1) white, handwritten: Sibiria occ.; 2) white, handwritten: sibiricus / Harold/ typ.; 3) white, printed: Ex Musaeo Harold; 4) red, printed: Aphodius sibiricus Harold, 1863 , Lectotypus, M. & G. Dellacasa des., 2001.
