Emphania subsmaragdina n. sp.

TYPE MATERIAL. — Holotype: ♂ “ Madagascar Fianarantsoa Perrot Frères , 2 e semestre 1892” ( MNHN).

ETYMOLOGY. — Derived from Latin, sub - (dark), smaragdinus (smaragd green).

DESCRIPTION OF HOLOTYPE

Length: 6.9 mm; length of elytra: 5.1 mm; width: 4.4 mm. Body surface dark green with greenish shine, partly reddish. Head as in E. metallica ; labroclypeus more subrectangular and anterior angles strongly rounded. Eyes small, ratio of diameter/interocular width:0.56.Antennal club twice as long as the remaining antennomeres combined and slightly reflexed; antennomeres 3 and 4 almost fused. Pronotum and scutellum as in E.metallica , but basal marginal line of pronotum very fine and indistinct,widely interrupted medially. Elytra as in E. metallica , but apical interior angle blunt, apical external angle convexly rounded, and apical border convex. Metacoxa and pygidium as in E. metallica , ratio of length of metepisternum/ metacoxa: 1/2.0. Legs as in E. metallica ; metatibia more slender and long, widest shortly before apex; ratio width/length: 1/5.4; the basal group of spines at basal quarter of metatibial length; medial metatibial face with one to four coarse punctures beside the dorsal margin; first metatarsomere a quarter of its length, longer than the upper tibial spur.

Aedeagus: Figure 2 M-O.

REMARKS

The species is, in shape of parameres, very similar to E.semiviridis n. sp. It differs from E. semiviridis n. sp. by the slightly larger body size, the presence of an elytral declivity, the longer antennal club being twice as long as the remaining antennomeres combined. The hook of each paramere in E. subsmaragdina n. sp. is more abruptly bent backwards and the paramere is more slender.
