Andrahomanus ovaliceps sp. nov.

( Figs. 40 , 47 )

Type locality. South Africa, Limpopo Province, Messina Nature Reserve, 22°21′S 30°03′E.

Type material. HOLOTYPE: ♀, ‘ S.Afr.: Limpopo Prov. Messina Nat. Res. 22.21 S – 30.03 E // 12.12.2000; E-Y: 3401 old baboon dung, leg. M. Burger, R. Müller’ ( TMSA).

Description (female, holotype). Body length 3.9 mm. Head and pronotum reddish; elytra black, at places (suture, base) with brownish tinge; legs reddish, distal portion of femora rather brownish, antennae reddish.

Head 1.3 times as long as wide, slightly unevenly rounded posteriorly; posterior temporal angles absent. Eyes small, moderately convex. Dorsal surface at most moderately glossy, finely reticulated and distinctly punctate; punctation simple, evenly developed. Setation very short, inconspicuous, appressed, with a few longer erect setae. Antennae moderately enlarged in terminal third; antennomere X 1.1 times as long as wide, antennomere XI 1.8 times as long as wide.

Pronotum 1.2 times as long as wide, at most slightly narrower than head including eyes, rounded anteriorly; pronotal disc convex; dorso-lateral sides uneven, moderately angulately protruding in posterior half in dorsal view ( Fig. 47 , marked by arrow). Surface nearly matt, finely reticulated including lateral sides and distinctly punctate dorsally; dorsal reticulation somewhat coarser and punctation denser than that on head. Setation as that on head; posterior dorso-lateral protuberances bearing a single erect seta each.

Elytra 1.8 times as long as wide, conjointly rounded apically. Surface smooth and comparatively glossy, rather densely and distinctly punctate; punctation similar to that on head, becoming finer and sparser towards elytral apices. Setation as that on head, very short, appressed; erect setae somewhat longer, more numerous and distinct, especially in apical third.

Legs simple; setation normally developed, short and fine, apical margin of meso- and metatibiae with some stiff setae.

Sternum VII simple; tergum VII simple, evenly rounded apically.

Differential diagnosis. Andrahomanus ovaliceps sp. nov. can be easily recognized by the oval head base, presence of paired dorso-lateral protuberances in the posterior half of the pronotum and the moderately glossy, finely reticulated surface of the head and pronotum combined with the rather sparsely punctate, glossy elytra.

Etymology. Composed from the Latin adjective ovalis (oval) and suffix -ceps (capped, head- ed), referring to the oval form of the head.

Distribution. South Africa.
