Redescription.
Length 6.0–11.0 mm. Body black to dark brown, antennae and legs dark brown. Head. Clypeus and frons with round punctures each with a central seta; antennae reaching 3/4 along lateral margin of pronotum; antennomere 9 longer than wide, with apical tomentose sensory patches arranged in two areas separated dorsally; antennomere 10 as wide as antennomere 11. Thorax. Pronotum widest behind midpoint; disc and lateral quarters with finer golden setae; punctures of disc same size as punctures of elytron; width of anterior margin exceeding half the width of posterior margin; lateral quarters convex, dorsal surface of lateral margin bearing a row of short golden setae; posterior angles right, apex rounded (
Fig. 25
); prosternum horizontal, with edge on anterior margin broadened below gula; prosternal process produced backwards, not reaching the midpoint of the space between pro– and mesocoxae (as in
Fig. 13
); prosternum and mesosternum with punctures. Elytron lacking grooves, with two or three carinae weakly defined, equidistant between suture and lateral margin (
Fig. 25
); dorsal surface with short golden setae; pseudopleuron with long setae arising on punctures; epipleuron with short setae arising on protuberances, lacking a row of setae on the edge of anterior quarter. Legs. Ventral surface of meso– and metafemora with a row of setae on posterior edge. Inner surface of meso– and metatibiae with long, fine setae. Metatibiae straight. Male genitalia. Rods of sterna IX “V”-shaped. Basal lamina of tegmen equal width throughout, with base concave. Lateral styles of tegmen with proximal margin ventrally concave, widest at base, with abundant setae on distal third of ventral surface. Median lobe moderate (0.75 <L/T
≤
1.00), distally broadened, with apical aperture large and apex rounded. Female genitalia. Paraprocts moderate (1.2 P/C
≤
2.0); baculi of coxite inclined 45°; proctigeral baculus extending proximad much beyond paraproct baculus; apicodorsal lobe of proctiger extending about ½ length of coxite.

Note: This specimen agrees with the description by
Germain (1855)
, and we have no doubt that the label´s handwriting belongs to Germain. Therefore we conclude that this specimen is a
syntype
of
Praocis aenipennis
.
Kulzer (1958)
stated that the
type
of
P. aenipennis
is in the
MNNC
, but currently is not there (
Camousseight 1980
and pers. obs.).
