ADULT MALE. — Coloration similar to that of female, but with white basal 

 bands on dorsum of some abdominal segments. TERMINALIA (Fig. 133). Apical 

 margin of eighth tergite (VIII-T) bearing numerous short stout setae (shorter 

 than those of the lobes of the ninth tergite). Lobes of the ninth tergite (IXT- 

 L) prominent, separated by no more than the width of one lobe, each bearing 

 numerous setae. Tenth stermte (X-S) crowned with numerous short spines, the 

 apical ones pointed, the outer ones blunt; basal arm (XS-BA) long, stout, 

 strongly curved, heavily sclerotized. Phallosome (Ph) formed of two large 

 heavily sclerotized plates. Each plate basally with a long stout pointed dorsal 

 arm (Ph-DA) (not bent at right angles as in C. salinarius) and a slender 

 pointed process nearly as large as the dorsal arm; each plate apically with a 

 curved stout bluntly pointed ventral arm (Ph-VA), finely denticulate on its 

 middle portion; between the dorsal and ventral arms arise four slender teeth 

 (Ph-T), the apical one appressed to the ventral arm. Claspette absent. Basi- 

 style (Bs) about two and one-half times as long as basal width, with outer
