Schizaspidia andamanensis (Mani)

Taxonomic position

Hymenoptera: Chalcidoidea: Eucharitidae

Diagnosis

Female: Body dark metallic green with some bluish tinge; head shiny metallic green; scape and pedicel yellow testaceous; rest brown. Tegulae yellowish; coxae concolorous with mesosoma; legs pale yellowish (except some brown infuscation at base of femora). Metasoma metallic green blue in anterior half; posteriorly and laterally suffused with coppery brown black coloration.

Head smooth; 1.4 x as wide as long; antenna 1182 serrate; scape 2.5x as long as its median width; head more densely pubescent above than below; sparsely longitudinally striate between eyes and scrobe above the level of antennal sockets; scrobe above the lower level of eyes. Mesosoma strongly rugose punctuate; mesoscutum with prominent transverse carinae; scutellum longitudinally striate with a distinct median furrow and short transverse carinae; tines of the scutellar fork 0.4x shorter than scutellum; scutellar processes broad, 0.48x as wide as the maximum distance between them, and with rather broad carinae; slightly tapering towards apex; not strongly convergent; almost without any distinctive curve (slightly bent towards each other in male). Apex of scutellar processes in female smooth without any clear visible carinae. Notauli distinct; axillae broadly united medially. Mesopleuron with strong punctuations with some smooth areas anteriorly; coastal cell of forewing broad; densely setose; stigmal vein perpendicular to marginal vein and moderately long; basal 1/4th of forewing bare. Forewing much infumated in apical half; infumation denser below and around stigmal vein; veins pale brown (except dark brown submarginal vein). Propodeum rugose punctuate. Petiole shorter than in male.

Male: Scape 2.7x as long as wide; head 1.4 x as wide as long. First flagellar segment with a branch; branches of flagellar segments only slightly flattened and cylindrical. Petiole 2.27x longer than coxa in male. Scutellar processes 1.17x longer in male than in female; almost of same width throughout except at extreme apex. Tines of the scutellar fork slightly convergent; bending in curve towards each other; carinae clearer in male than in female.
