Diagnosis

Diagnosis. Males can be identified by examination of the genitalia. The females have tegmina more elongate (LTg/BTg more than 2.44), with costal margin slightly sinuate and white spots of hind wings less developed than in C. sanguiflua.
Description. LT: male (n = 13): 13.3 mm (11.9–14.2); Female (n = 7): 14.8 mm (14.3–15.4). Head: variegated, grey-olivaceous to brown-olivaceous; sides of vertex darker; lateral sides of head paler; clypeus and labium reddish brown; antennae brown; frons with unprecise, transverse, paler markings; ratio BV/LV = 3.5-4.5; BF/LF = 2.0. Thorax: pro- and mesonotum coloured same as head, often with two paler patches on posterior half of disc; metanotum and ventral face bright red; ratio LP+LM/BT = 0.90; LM/LP = 2.6. Tegmina: brown to dark brown with irregular paler, testaceous to green-olivaceous markings, covered with white waxy secretion in fresh specimens; larger transverse paler marking on corium close to base, showing a median brown stripe in males; clavus with median paler marking; paler marking at postero-costal angle and spots more numerous apically; veins suffused with green; ratio LTg/BTg = male: 2.63, female: 2.56 (2.44–2.7). Hind wings: brown with base bright red; pale white spot apically at each angle; females with spots smaller and postero-sutural spot often obsolete. Legs: bright red with tibiae and tarsi darker; spines of hind legs brown to black. Abdomen: bright red with genitalia testaceous. Genitalia male: lateral process of gonostyli digitiform, rounded apically, placed at basal third of height in lateral view, placed laterally in ventral view; gonostyli in ventral view with internal margins in contact on most of length and external margin slightly concave after process; aedeagus with dorsal margin nearly straight and ventral margin slightly concave apically in lateral view, not showing small teeth.
