urn:lsid:zoobank.org:act: F640EE01-ADBC-46DD-BF9B-0688B8A554E9
Figs 8–9
Diagnosis
Identical with C. geminiramus sp. nov. in almost all characters, but differs from the smaller C. geminiramus and from all other species of Cryptocorypha by the presence of setae on podous body rings (Fig. 8).
Further differs from C. geminiramus by the smooth part of head capsule extending well above antennal sockets (Fig. 8D, compare with Fig. 2A), by having the gonopod coxa (cx) more regularly hemispherical (Fig. 9A, C) and by having a jagged semicircular ridge (velum?, ve) on the basal part of the gonopod telopodite (Fig. 9B, D).
Etymology
The species epithet (noun in apposition) means ‘bearer of cacti’ and refers to the some cactus-shaped metazonital setae.

Referred specimen, not a type
TANZANIA • 1 ♀; Udzungwa Mountains, Iringa Region, Udzungwa Scarp Forest Reserve, above Chita Village; 1600–1650 m a.s.l.; 8–13 Nov. 1984; N. Scharff leg.; montane forest, litter; NHMD 621839.
Description
SIZE. Males: Length 5.3–5.5 mm; maximal body width (across metazona) 0.91–0.92 mm; 17 podous + 1 apodous ring + telson. Female: Length 7.7 mm; maximal body width (across metazona) 1.19 mm; 18 podous + 1 apodous ring + telson.
OTHER CHARACTERS. Virtually identical to the smaller C. geminiramus sp. nov. with the following exceptions: All level 1 tubercles and all lateral paratergal lobes on podous and apodous rings with a club-shaped, ornamented club-shaped, somewhat cactus-like seta (Fig. 8C); smooth part of head capsule extending well above antennal sockets (Fig. 8D); gonopod coxa (cx) more regularly hemisphaerical (Fig. 9A, C); basal part of gonopod telopodite with a jagged semicircular ridge (velum?, ve), on the basal part of the gonopod telopodite (Fig. 9B, D).
Remarks
Almost all specimens of C. cactifer sp. nov. were found in mixed samples with C. geminiramus sp. nov. The single female from Udzungwa Scarp Forest Reserve fully matches the females from Udzungwa Moutains National Park, but in the light of the considerable geographical distance, combined with the absence of a male, the specimen from Udzungwa Scarp Forest Reserve is not included in the type series.
If the Afrotropical alternative in the first couplet of the key provided by Golovatch (2019) is chosen, C. cactifer sp. nov. runs to C. diffusa (Brolemann, 1920) from which it differs by several characters, especially by strongly different gonopods and hairy tergites. If the Asian alternative in the first couplet is chosen, C. cactifer sp. nov. runs to couplet 17(18) where it fits neither alternative.
