Prosymnus arsus Opitz , new species ( Figs. 21 , 29 , 36 , 37 )

Holotype. ♂. Mozambique, Sofala P, 30 km S Caia , 76 m, 18.02 S- 35.12E. A second label reads: 21.12.2005, E-Y:3709, light trap, leg. Gussmann, Müller ( TMSA).

Diagnosis. The members of this species resemble those of P. mulleri Opitz , new species. But in specimens of P. arsus specimens, the elytral punctures are larger and the dorsum shows less of a metallic sheen.

Description. Size: Length 6.5 mm; width 2.8 mm. Form: As in Fig. 21 . Color: Cranium, pronotum, and elytra red-brown, antennae, pterothorax, abdomen, and legs testaceous, elytra with a slight metallic sheen. Head: Antennal capitulum lax, antennomere 9 cupuliform, antennomere 10 triangular; eyes much narrower than frons (EW/FW 25/47). Thorax: Pronotum transverse (PW/PL 130/115), no spine on pronotal posterior angle; elytral disc sculptured with 12 striae of punctation that extends to elytral apex, elytral interstitial spaces smooth and shiny. Abdomen: Setal patches on 4 th sternite; male pygidium scutiform; aedeagus as in Fig. 29 .

Natural History. The holotype was collected in December, at 76 m elevation.

Distribution. This species is known only from Mozambique ( Fig. 37 ).

Etymology. The specific epithet arsus (= shine) is a Latin adjective. The name describes the shine that emits from the elytral disc.
