Jamaha Gnezdilov & O’Brien, 2008

Type species. Poeciloptera elevans Walker, 1858 ; by original designation.

Emended diagnosis (modified from Gnezdilov & O’Brien 2008). Body elongate, forewings narrow, nearly parallel-sided. Vertex quadrate, just wider than long, medially concave, apex weakly convex, posterior margin strongly concave. Frons roughly rhomboid, widest near level of antennae, median carina present, frontoclypeal suture sinuate or convex. Pronotum short, mesonotum about 4x length of pronotum along midline. Forewings widely rounded apically, Sc+RA, MP, and CuA all originating near apex of basal cell. Hind tibia with single lateral tooth. Male pygofer with hind margin bearing long process medially.Aedeagus without ventral hooks, with multiple branched dorsolateral phallobase lobes (which may be bilaterally asymmetric).Anal tube varied. Female ( Gnezdilov & O’Brien 2008, Figs 70-71) with gonoplacs rounded, not fused medially. Median field of posterior connective lamina of gonapophyses IX comprised of two areas that bear median denticles accompanied by larger lateral teeth. Lateral fields of the laminae without processes. Gonocoxa VIII with weakly convex hind margin. Endogonocoxal process narrowing apically. Anterior connective lamina of gonapophysis VIII with 3 teeth in apical group and 3 keeled teeth in lateral group.

Remarks. The elongated posterior projection on the lateral margins of the male pygofer is a diagnostic feature of the genus. Gnezdilov & O’Brien (2008: 23) also specified that the genus is distinguished from Colpoptera “by the narrow and elongated parts of the ovipositor which probably represents a different manner of oviposition – the elongated and fused gonoplacs are probably used as a directing case for the narrow and pointed endogonocoxal processes and anterior connective laminae in oviposition.” Gnezdilov & O’Brien (2008) made comparisons between species in Jamaha and Colpoptera sinuata Burmeister, 1835 , the type species of Colpoptera , including a male and female syntype from the Museum für Naturkunde der Humboldt-Universität, Berlin, Germany. This is significant because the monophyly of Colpoptera as currently comprised has yet to be assessed. At present, there have been no external features proposed that serve to distinguish among the genera Colpoptera , Jamaha , and Caudibeccus .
