Appearance
Male :Body. Brown to green with black patches scattered over body and legs.
Head. Longer than wide, notched dorsally between antennae. Vertex with a prominent blunt elevation. Elevation split by a shallow longitudinal depression. Eyes circular and strongly projecting hemispherically. Antennae slightly setose, widely projecting over apex of abdomen. Scapus slightly flattened dorsoventrally, subcylindrical in cross section. Pedicellus shorter than scapus and round in cross section. Following segments narrower than pedicellus and varying in length towards apex.
thorax. Pronotum with anterior margin slightly concave, followed by a transverse groove. A longitudinal median groove starting at anterior edge, not reaching posterior tubercle. Centrally a definite transverse depression. Posteromedially with a small, blunt tubercle. Mesonotum scarcely granulose, slightly widening towards the posterior. Posteromedially with a definite blunt spine, posterolateral edges humped. Metanotum about as long as pronotum. Posteromedially with a definite blunt spine. Postero- lateral edges humped.
aBdoMen. Median segment slightly widening towards posterior with a blunt spine posteromedially. Terga II–VIII with short, tapered lobes posterolaterally and with a blunt elevation posteromedially. Tergum IX slightly laterally compressed. Tergum X with posterior edge incised, posterolateral angles rounded, armed ventrally with small black spines. Vomer well developed, visible as an elongated, flattened spine. Apex of vomer visible dorsally between lateral edges of tergum X. Poculum triangular in ventral view, fairly flattened. Poculum narrowing towards posterior, apex rounded, reaching apex of tegum IX. Cerci cylindrical in cross section, apices incurved and blunt, projecting over apex of abdomen. Abdominal sterna smooth.
Legs. Long, profemora compressed and curved basally. Femora and tibiae compressed laterally, with all carinae developed. Basitarsi longer than following tarsomeres combined. Claws small.
Female :
Body. Brown to green with black patches scattered over body and legs.
Head. Longer than wide, notched dorsally between antennae. Vertex with a prominent blunt elevation. Elevation split by a shallow longitudinal depression. Eyes circular and strongly projecting hemispherically. Antennae slightly setose, almost reaching apex of abdomen but broken. Scapus slightly flattened dorso- ventrally, subcylindrical in cross section. Pedicellus shorter than scapus and round in cross section. Following segments narrower than pedicellus and varying in length towards apex.
tHorax. Pronotum with anterior edge incurved and raised, followed by a transverse groove. A longitudinal median groove starting behind anterior edge, not reaching posterior tubercle. Slightly constricted submedially, with a second transverse impression. Posteromedially with a small, blunt tubercle. Mesonotum scarcely granulose, slightly widening towards posterior. Posteromedially with a definite blunt spine. Lateral margins projecting posterolaterally. Metanotum shorter than pronotum. Posteromedially with a definite blunt, spinose tubercle. Lateral margins projecting posterolaterally.
aBdoMen. Median segment widening towards posterior with a blunt spine posteromedially. Terga II– VIII with posterolaterally well developed lobes and posteromedially with a curved, slightly laterally compressed spine. Abdominal terga IV–V widest. Terga VIII–X laterally compressed. Tergum X with posterior edge incurved, posterolateral angles rounded mediolaterally with a small lobe. Epiproct small, visible as small, posteriorly rounded plate; not projecting over posterolateral angles of tergum X. Cerci small, cylindrical in cross section, apex rounded, slightly projecting over apex of abdomen. Abdominal sterna smooth. Subgenital plate compressed laterally, rounded posteriorly, not reaching apex of abdomen.
Legs. Long when compared to body. Profemora compressed and curved basally. Femora and tibiae compressed laterally, with all carinae developed. Meso- and metafemora slightly widening towards the posterior. Basitarsi longer than following tarsomeres combined. Tarsomeres gradually decreasing in length and with dorsal carina well developed, resulting in a posteromedian ridge. Claws small.
