Genus Amorphoscelis Stål, 1871

Type species: Amorphoscelis annulicornis Stål, 1871 .

DIAGNOSIS. Small-sized and dorso-ventrally flattened. Head wider than the pronotum, with distinct juxtaocular bulges. Compound eyes rounded with three ocelli. Lower frons narrow. Antennae long and filiform, extending beyond the tip of the abdomen. Pronotum short, longer than wide, with a more or less bumpy dorsal surface. Forecoxae smooth. Forefemur with one DS, without AvS or PvS. Foretibiae with only one tibial spur. Foretarsus longer than foretibiae. Both sexes are winged. Meso- and metathoracic femora robust. Male abdomen long and narrow. Male supra-anal plate transverse and triangular. The last segment of the cerci in both males and females is considerably enlarged and flattened. Styli present on the subgenital plate.

REMARKS. The philippina species group of Amorphoscelis , formerly including A. philippina , A. sulawesiana and A. siebersi , only been recorded from Oriental region ( Roy, 2010). The philippina species group can be easily distinguished from annulicornis species group by the shape of male genitalia structures. In the philippina species group, the apical process of the male genitalia is more or less simple without lateral extension (in annulicornis species group, with lateral extension), ventral phallomere with an extension only on the left side, pointed or not (in annulicornis species group, always with two extensions on the left side).
