D e r i v a t i o n o m i n i s: The new species is dedicated to Michael Langer who collected most of the types .

D e s c r i p t i o n. 5.9-7.2 mm. Body elongate, moderately convex, dorsal surface with weak transverse, sometimes almost obsolete microreticulation, moderately shiny, with densely and long yellowish setae. Colour brown to piceous.

M a l e. Habitus as in Fig. 1 . Head large, moderately semicircular, feebly convex at middle, without tubercles, anterior margin of clypeus truncate medially, sides broadly and regularly rounded to genae. Genae rounded; eyes distinctly protruding. Punctation simple, with regularly distributed punctures, interstices 0.5-1.5 times as wide as diameter of punctures.

Pronotum transverse, anterior angles rounded and feebly protruding. Sides regularly rounded, feebly sinuate before the indistinct and widely rounded posterior angles. Basal margin slightly protruding posteriorly, weakly sinuate on either side. Lateral border distinct, anterior and posterior border lacking. Lateral and basal margins with rows of short dense yellowish setae. Punctation simple with regularly distributed punctures; interstices 1-2 times as wide as diameter of punctures.

Scutellum triangular with several punctures.

Elytron long, 1.5-1.6 times as long as combined width of elytra, widest at middle, humerus without denticle. Striae narrow, moderately deep and crenulate. Punctation of intervals between striae slightly finer and sparser that that of head and pronotum; intervals nearly flat, only sutural interval distinctly convex.

Anterior margin of profemur with small but distinct sharp teeth. Protibiae long and slim, externally with three large triangular teeth and 11-13 small denticles, apical spur distinctly longer than wide, truncate, curved inwards and downwards ( Fig. 5 ). First metatarsomere as long as the following three combined, longer than superior spur. Mesotibiae without inferior apical spur. Protarsus in both sexes long, nearly as long as protibia. Protibia only very finely and sparsely punctured in both sexes and nearly glabrous.

Metasternal plate flat, shiny, with fine microreticulation, medially with distinct impressed line; marginally with a row of dense punctures and medially with some irregular punctures in the two anterior thirds, medial punctures with short depressed seta and marginal punctures with longer, nearly erect seta.

Aedeagus as in Fig. 3 and 4.

F e m a l e. Habitus as in Fig. 2 . Lateral margin of pronotum feebly rounded and in posterior half nearly subparallel. Protibiae shorter and wider, apical spur simple, slender and acute, curved outwards and less distinctly downwards. Profemur without teeth at anterior margin. Mesotibiae with inferior apical spur, the latter half as long as superior spur.

Metasternal plate flat, shiny, with fine microreticulation, medially with weakly impressed line; marginally with a row of irregular punctures and medially with some irregular punctures in the two anterior thirds, medial and marginal punctures mostly with short depressed seta.

D i a g n o s i s Aphodius (Brachiaphodius) langeri nov.sp. is most similar to A. (B.) pilosus HAROLD 1874 and A. (B.) jendeki KRÁL 2000 . These three species share the

following diagnostic characters: dorsal surface mostly microreticulate, elytra long, humerus without denticle. The new species differs in having the terminal protibial spur in the male distinctly longer than wide ( Fig. 5 ) and the phallobasis approximately as long as the paramere ( Fig. 3, 4 ). Also, the protarsus is distinctly longer, nearly as long as protibia, which is very finely and sparsely punctured in both sexes and nearly glabrous.
