Description
Lateral margins of pronotum and corium with yellowish narrow stripe; anterior angles of ventrites and connexival laterotergites with yellowish spots. Metasternal evaporatorium with long and curved peritreme. Membrane brownish or whitish.
Pygophore slightly longer than wide; lateral walls very slightly concave in middle of length; dorsal infolding slightly shorter, without impression, dorsal wall slightly longer than in C. melanopterus.
Paramere (Figure 3 A –3 D). Hypophysis strongly curved dorsally, so that its apex is visible from outer view.
Aedeagus (Figure 4 A, 4 B). Ventral lobe of conjunctiva barely reaching apical margin of theca and narrowed before widened apex; latter with two small lateral denticles directed laterad and with two nariform impressions dorsal to them (Figure 6 A, 6 C, 6 D, 6 F) or rarely without denticles and impressions (Figure 6 G, 6 I); ventral surface of lobe slightly convex, without carina; in lateral view, lobe rather narrow (Figure 6 B, 6 E, 6 H). Apical lobes of conjunctiva short, directed ventroposteriad, lying completely in dorsoventral plane of apical half of conjunctiva and curved one towards other in middle. Vesica without lateral branch. Dorsolateral lobes of conjunctiva long, basally divided by impression, divergent in a V-shape, directed dorsolaterad, and curved anteriad at apices. Anterior wall of each dorsolateral lobe with area of weak sclerotisation before apex. Spicule broad at base, tapering to pointed apex, basally directed anteriad and dorsad, curved mediad before apex. Inner end of spicule basal plate with one short conical denticle directed mediad.
Gynatrium (Figure 9 A). Posterior pouches located behind posterior margin of gynatrial sac; line of posterior margin laterally curved posteriad and extending on dorsal walls of pouches (Figure 12 A). They are rather large, approximately as long as wide, with wide base and widely rounded posterior margin in dorsal view. Their walls rather soft, inner walls evenly convex, not sloped. Pouches subtransparent, without any sclerotisations inside. Anterior part of gynatrial sac very long and wide. Proximal part of spermathecal duct very short; median part elongated; distal part as long as half of median part or slightly shorter. Tubular part of spermathecal capsule approximately as long as transverse diameter of its spherical part and curved, but not gyrose (Figure 9 B). First rami (Figure 8 H, 8 I) rather broadly widened anteriorly, at anterior ends truncate at acute angle, rarely slightly widening and with rounded anterior end.
