Emphania semiviridis n. sp.

TYPE MATERIAL. — Holotype: ♂ “Chaînes anosyennes Massif nord, 1050 m moyenne Ranomandry 11/ 30-XI- 1971 / Muséum Paris Madagascar Est mission C.N. R.S. R.C.P. nº 225” ( MNHN).

ETYMOLOGY. — Derived from Latin, semi - (half), viridis (green).

Length: 6.5 mm; length of elytra: 4.5 mm; width: 3.8 mm. Body surface dark green with greenish shine, partly reddish. Head as in E. metallica ; ocular canthus without terminal setae. Eyes, ratio of diameter/interocular width: 0.63. Antennomeres 3-5 fused; antennal club 1.5 times longer than the remaining antennomeres combined. Pronotum and scutellum as in E. metallica . Elytra as in E. metallica but without convex semicircular declivity, apical interior angle convex, apical external angle oblique, and apical border convex. Metacoxa and pygidium as in E. metallica ; tooth of posterior external angle of metacoxa moderately sharp. Ratio of length of metepisternum/metacoxa:1/2.0. Legs as in E.metallica ; posterior legs lacking in the holotype.

Aedeagus: Figure 2 G-I.

REMARKS

The species shares the fused antennomeres 3-5 with the similar E. metallica . Emphania semiviridis n. sp. differs from E. metallica by the smaller body size, the lacking posterior elytral declivity, the longer antennal club being 1.5 times longer than the remaining antennomeres combined, and the shape of male genitalia having the distinctly shorter parameres with a sharply pointed apical hook.
