Pace, R., 2012, New data and new species of Aleocharinae from Tropical Africa in the Natural History Museum of the Humboldt University, Berlin (Coleoptera, Staphylinidae), Linzer biologische Beiträge 44 (2), pp. 1331-1362 : 1341-1342

Diplopleurus anterugosus nov.sp. ( Figs 45-48 )

T y p e m a t e r i a l: Holotype, Kamerun, Bosum, bei Termiten, leg. Tessmann (MNHUB). Paratypes: 15 specimens, same origin (MNHUB).

D e s c r i p t i o n: Length 4.7 mm. Body shiny and reddish, elytra reddish-brown with posterior external angle yellowish and with a inverted reddish sutural triangle, abdomen reddish-brown with pygidium reddish, antennae reddish with the two basal antennomeres yellowish-red, legs reddish. Body devoid of reticulation. Puncturation of the head strong, deep and absent on the longitudinal median band, that of the pronotum superficial, that of the abdomen strong and composed of elongate punctures. Granulation of the elytra evident. Head with a bump between the antennae and a broad median sulcus. Pronotum with evident lateral depression and with a posterior median fossa. Aedeagus Figs 46-47 , spermatheca Fig. 48.

C o m p a r a t i v e n o t e s: In the form of the aedeagus, the new species is similar to D. varius PACE 1999 from Namibia. It differs for the broad median sulcus of the head, absent in D. varius , in the pronotum being less transverse than that in D. varius , with a width/length ratio equal to 1.3, while in D. varius this same ratio is equal to 1.45. The aedeagus of the new species has the preapical portion, in ventral view with parallel sides as in D. varius , but this portion is wide and short, in D. varius narrow and long. The aedeagus of the new species is ventrally sinuous, that of D. varius broadly arched.

E t y m o l o g y: The name of the new species derives from the wrinkled surface of head and pronotum.
