Diagnosis. Males of C. plumosum are closely related to those of C. severum in having a long embolus, but can be distinguished from the latter species by the presence of a wide cymbial retrobasal process (vs. absent in C. severum ), strongly spiralled embolus (vs. weakly in C. severum ), and obliquely oriented loop of sperm duct (vs. longitudinally oriented in C. severum ) (cf. Figs 3C–D View FIGURE 3 , 5C View FIGURE 5 with Figs 4C–E View FIGURE 4 , 5D View FIGURE 5 ).

Redescription. Male (holotype, Fig. 3A–B View FIGURE 3 ) in alcohol (somatic features after Thorell (1881)). Prosoma pitchblack, unevenly covered with greenish-grey feathery setae, almost twice as long as its width, with thoracic striae. Fovea short, distinct. AER strongly recurved, PER strongly procurved ( Fig. 3B View FIGURE 3 ); ALEs oblong, all other eyes round ( Fig. 3B View FIGURE 3 ). Sternum pitch-black, sub-elliptical, pubescent. Opisthosoma subovate, black, with median, transverse constriction ( Fig. 3A View FIGURE 3 ), with three transverse greenish-grey stripes. Anterior legs brownish, posterior blackish, with greenish-grey spots and stripes on all femora. Body length 7.0. Pedipalp ( Figs 3C–D View FIGURE 3 , 5C View FIGURE 5 ): cymbium retrobasally with flat, triangular process, retrobasal paracymbial spine shifted apically onto this process ( Fig. 3C View FIGURE 3 ). Tegulum pearshaped, with less coiled sperm duct having obliquely oriented loop ( Fig. 3C View FIGURE 3 ). Embolus moderately long, forming open spiral, with broad proximal part and blunt tip directed at 11-o’clock in ventral view ( Figs 3C View FIGURE 3 , 5C View FIGURE 5 ).

Female. Unknown.

Distribution. Indonesia ( Moluccas) ( Thorell 1881).
