Geodromicus, L. Redtenbacher, 1857

Shavrin, Alexey V., 2019, The crassipalpis species group of the genus Geodromicus Redtenbacher, 1857 (Coleoptera: Staphylinidae: Omaliinae: Anthophagini), Zootaxa 4686 (4), pp. 571-580 : 577-579

Geodromicus sp.

( Figs. 10 , 12 )

Material examined: 2 ♂♂, 1 ♀: ‘ CHINA, Gansu, Dalijia | Shan , 60 km W Linxia | 3475m, 11.VII.1994 | A.Smetana [C8 = specimens were taken from soaking wet moss in seepage on an almost vertical wall near a small river]’ (temporarily in CS, to be eventually deposited in NSMT) .

Remarks. Regarding coloration, size of the body (5.60–6.40 mm), the punctation and microsculpture of the forebody, the internal structure of the aedeagus, and the presence of short setae on medial edges of the parameres ( Fig. 10 ), the above specimens ( Fig. 12 ) are similar to G. amplissimus , from which they differ by less protruded anterior angles of the pronotum and a wider (deformed?) median lobe. Both males are partly damaged: one specimen lacks the left paramere ( Fig. 10 ); in the other male the apical part of the abdomen including the basal portion of the aedeagus is significantly damaged.
