Figs 10–11 View Fig View Fig

Diagnosis

Differs from all congeneric species by the unique shape of the ‘snakelike’ gonopod telopodite. Agrees with C. geminiramus sp. nov. in non-gonopodal characters.

Etymology

The species epithet means ‘out of the egg’ and refers to the shape of the gonopod which somewhat resembles a snake (telopodite) hatching from the egg (coxa).

Material examined

Holotype TANZANIA • ♂; Morogoro Region, Udzungwa Mountains Natl Park, Mito Mitatu ; 07°50′14.3″ S, 36°50′46.8″ E; 1207 m a.s.l.; 16 Dec. 2013; T. Pape and N. Scharff leg.; pitfall trap, Plot MM1; NHMD 621840 . GoogleMaps

Description

SIZE. Male: Length 5.3 mm; maximal body width (across metazona) 0.78 mm; 17 podous + 1 apodous ring + telson. Female: unknown.

OTHER NON- GONOPODAL CHARACTERS ( Fig. 10 View Fig ). Virtually identical to C. geminiramus sp. nov.

GONOPODS ( Fig. 11 View Fig ). Coxa (cx) moderately globose, its surface scaly and with scattered level 3 spherules, mesally forming a shallow gonocoel. Cannula ( Fig. 11C, E View Fig : ca, not seen in the other two species) with a few tiny denticles (de).Telopodite projecting strongly from gonocoel, very evident in lateral and ventral views. Basal (‘prefemoral’) part of telopodite (bt) massive, with several distolateral setae, giving rise to a very long, sinous shaft which slightly beyond its midlength divides into a slightly curved branch, probably corresponding to an exomere (ex), and a strongly S-shaped branch, probably the solenomere (slm). A velum is not evident.

Remarks

A male of C. geminiramus sp. nov. was found in the same pitfall trap as the unique holotype of C. exovo sp. nov.

If the Afrotropical alternative in the first couplet of the key provided by Golovatch (2019) is chosen, C. exovo sp. nov. runs to C. diffusa (Brolemann, 1920) from which it differs by several characters, especially by strongly different gonopods. If the Asian alternative in the first couplet is chosen, C. exovo sp. nov. runs to couplet 17(18) where it fits neither alternative.
