Redescription. Dorsal colour mostly opaque green, usually with black markings on head, face, pronotum, forewing and other parts of body showing variable degrees of sexual dimorphism, female usually with reduced black markings (Plate I: A–H).

Head slightly broader than pronotum; crown broad and short, blunt-roundish produced, somewhat flat with transverse discal furrow, not rounded at meeting line with frons but comparatively sharp angled; coronal suture distinct; ocelli in fore margin distant from eyes by about their own diameter (Plate I: A–G). Face broad; anteclypeus tapered; frontoclypeus moderately broadening dorsad; ocellocular area rather broad (Plate I: H). Pronotum broad, sides parallel (Plate I: A–G). Forewing long; appendix distinct, extended around wing apex; four apical cells and two closed subapical cells, outer triangular and much shorter and smaller than central, clavus with two veins, marginal vein complete in hind wing, first cubitus bifurcate and vannal veins 1 and 2 separate (Plate I: I– J).

Profemur setal row AV with 11–12 similar peglike setae; AM1 present ( Fig. 5A ). Foretibia dorsal macrosetal formula 4+4 or 6+4 ( Figs. 5 B–C). Hind femur setal formula 2+2+1 ( Fig. 5 D). Hind tibia setal row AD with approximately 10 long stout setae and 0–5 shorter setae between each long seta ( Fig. 5 E); pecten with several normal macrosetae and 2 platellae; PD with approximately 9–11 macrosetae, 0–2 shorter setae between each long seta, hardly as long as those of AD ( Fig. 5 F).

Pygofer heavily sclerotized, side lobe usually with one or more thickened and modified macrosetae near apex, no appendage ( Figs. 17 A–E); anal tube broad, nearly reaching apex of pygofer, heavily sclerotized ventrally, weakly sclerotized dorsally; valve short, broad triangular ( Fig. 2 H); subgenital plate triangular, heavily sclerotized, macrosetae usually uniseriate ( Figs. 3 A–E); style well-developed, apophysis long and rather thick ( Figs. 3 F–L), preapical angle of style below apophysis sharply triangularly elongate ( Figs. 3 F–L); connective long, Y-shaped, with anterior arms separate anteriorly ( Fig. 12 G); aedeagus with large basal socle ( Figs. 4 E–I), shaft robust, arising from hinge-like joint at ventral part of socle, slightly curved dorsad, with pair of lateral processes and, in most species, on dorsal surface elongate sclerotised carinae with variable numbers of spines directed distad ( Figs. 4 E–I); gonopore subapical on dorsal surface.

First valvula dorsal sculpturing granulose to maculose, submarginal for most of length (Plate VII: G–H). Second valvula abruptly broadened ~3/5 its length from base, with small obliquely triangular dorsal teeth over nearly apical half (Plate VII: I–J).

Distribution. Widespread in Old World ( Oman, Knight & Nielson 1990).
