Diagnosis.

The male of C. jaegeri resembles those of C. cavernicola (Wunderlich, 2011: 433, figs 8-18) in having a large and flat, laminar median apophysis which bears a tiny needle-shaped distal horn (Fig. 4A-C) (vs. median apophysis relatively small, consisting of triangular base and biforked distal horn in C. bifidum sp. nov.; Fig. 2C), but differs in the combination of genitalic and somatic characters: distal apophysis of the tegulum is erect, apex relatively sharp, pointing distally (Fig. 4C; Wunderlich 2011: 435, fig. 18b) (vs. curved, apex truncated, pointing proximally; Wunderlich 2011: 433, fig. 17); cymbium apically-ventrally with a pair of long and bristle-shaped hairs on a hump (Fig. 4C; Wunderlich 2011: 435, fig. 18b) (vs. cymbium bearing apically four tiny hairs which are not situated on a hump; Wunderlich 2011: 433, fig. 17); both anterior and posterior eye rows with 4 eyes (Fig. 3A) (vs. anterior eye row with 6 eyes, posterior eye row with 2 eyes; Wunderlich 2011: 433, figs 8-10). Females of C. jaegeri are similar to those of C. thakekensis (Lin et al. 2014: 98, figs 17A-E, 18A-C) by the epigynal plate with a long, rugose scape, and by the similar configurations of vulva, but they can be differentiated by the circular main spermathecae separated by about 1/3 of their diameter (Fig. 3G) (vs. semi-circular main spermathecae separated by about 1.2 × their width; Lin et al. 2014: 98, figs 17C, E, 18C), the accessory spermathecae consisting of a tubular stalk and globular head (vs. accessory spermathecae claviform, not subdivided; Lin et al. 2014: 98, figs 17C, E, 18C), and by the strongly sclerotized fertilization ducts (Fig. 3G) (vs. membranous FDs; Lin et al. 2014: 98, figs 17C, E, 18C).
