Description

Distinguished from all other species by lateral margins of pronotum, corium, abdominal venter and connexivum without light stripes and spots, unicolour with other parts of body. Metapleural evaporatorium with long and curved peritreme. Membrane brownish, opaque.

Pygophore as in C. niveimarginatus but with slightly longer dorsal wall.

Paramere. Sensory process more strongly curved dorsad than in all previous species, rather long, widely rounded at apex ( Figure 3 M ).

Aedeagus almost as in C. niveimarginatus . Ventral lobe in ventral view slightly narrower, with almost parallel lateral margins, very slightly convex distal to middle and slightly converging apically; extreme apex of lobe short and narrow ( Figure 6 X ); ventral wall flattened over entire surface; in lateral view, lobe rather narrow, with rectangularly rounded apex ( Figure 6 Y ).

Gynatrium as in C. mixtus , with somewhat smaller apical part of gynatrial sac ( Figure 11 E ). First rami moderately wide anteriorly and acutely ( Figure 8 X ) or rectangularly ( Figure 8 Y ) rounded at anterior end.

Measurements

Body 6.55–8.40 in length, 3.85–5.05 in width; pronotum 3.55–4.50 in width; head 1.57–1.89 in width; ocular index 3.74–3.95; length of antennal segments I–V: 0.35–0.46: 0.64–0.83: 0.63–0.77: 0.90–1.09: 0.94–1.06.

Distribution
