Bhaskaraena gen. nov.

Type species: B. nigrifrons sp. nov.

ETYMOLOGY. The name is modified from “ Bhaskara ”, in acknowledgment of the generous contribution of Mr Edy Bhaskara ( Indonesia) to the present work. It is feminine in gender.

DIAGNOSIS. The genus can be recognized on the following combination of characters: (1) frons with 2 longitudinal carinae and with lateral margins bisinuate;

(2) cephalic process short and narrow, shorter than frons, pointed apically, directed dorsally and sinuate basally;

(3) tegmina opaque and coloured; with costal and sutural margins parallel and apical margin obliquely truncate; with numerous longitudinal veins at nodal line;

(4) hind wings mostly opaque and coloured, with posterocentral hyaline area;

(5) pronotum with one median carina;

(6) paradiscal carinae of mesonotum curved.

DESCRIPTION

Head: ( Figs 4 B, D, F ; 5 B, D, F ) Vertex excavate, subquadrate and with lateral margins carinate; lateral carinae extending along posterodorsal face of cephalic process; hind margin not carinate. Frons narrowing towards dorsum, with 2 longitudinal carinae not reaching frontoclypeal suture ventrally and extending dorsally on the anterolateral margins of cephalic process; lateral margins bisinuate under level of ocelli, extending dorsally on side of cephalic process. Cephalic process shorter than frons, projecting anteriorly at base and pointing dorsally; narrow groove dorsally left by lateral margins of vertex not fused. Clypeus elongate, slightly narrower than frons basally and longer than combined length of frons and cephalic process. Labium very elongate and narrow, surpassing hind trochanters. Ocelli present. Eyes large, about as long in dorsal view as breadth of vertex. Antennae with scape short, ringshaped and pedicel globulose; not surpassing level of eye.

Thorax: ( Figs 4 B, F ; 5 B, F ) Pronotum with strong median carina with impressed point on each side; dorsolateral carina sinuate; lateral carinae visible in dorsal view along anterior half, angularly rounded anteriorly; anterolateral angles slightly projecting anteriorly. Mesonotum with median carina; peridiscal carinae roundly curved.

Tegmina: ( Figs 4 A ; 5 A ) Elongate and narrow, more than 3 times as long as broad, with costal and sutural margins subparallel, slightly broadening on sutural margin after nodal line; costal margin very slightly emarginate et level of nodal line. Apical margin obliquely truncate. Opaque and coloured. Very dense reticulum of longitudinal veinlets and crossveins, especially posteriorly to nodal line. Clavus open.

Hind wings: ( Figs 4 A ; 5 A ) Well developed, elongate and narrow with apical margin rounded; mostly opaque with posterocentral hyaline area; brown with basal, elongate, brightly coloured patches not surpassing level of hyaline area.

Legs: ( Figs 4 C ; 5 C ) Elongate and slender. All femora and pro- and mesotibiae with pale and dark rings. Metatibiae with 6 lateral and 7 apical spines. Basal tarsomere longer than combined length of second and third tarsomeres.
