Coleocydnus ruwenzoricus CZAJA & J. A. LIS, sp. n.

( Figs 13- 18)

Diagnosis

The new species is similar to C. emsti in its general habitus, but can easily be distinguished from the latter by its body colour (castaneous to dark brown, distinctly darker than body of C. emsti), a number of submarginal setigerous punctures on submargins of the head (2-3 in C. ruwenzoricus ; 3-4 in C. ernsti ) and the pronotum (3-4 in C. ruwenzoricus ; 5-6 in C. ernsti ). Moreover, both species differ in a character of the body puncturation - C. ernsti has almost impunctate pronotum and scutellum, and densely punctured mesocorium, whereas a dorsal surface of C. ruwenzoricus is shallowly and densely punctured. For characters separating the latter from the others species see the key.

Description

Body medium sized (4.70-6.00 mm in length, 3.0- 3.7 mm in width), castaneous to dark brown, weakly convex ( Fig. 13).

Head castaneous to dark brown, shining, 0.81 -1.07 mm in length; clypeus impunctate, slightly concealed by paraclypei, bearing no subapical setigerous punctures; each paraclypeus with a row of 2-3 submarginal setigerous punctures bearing hair-like setae; eyes reddish brown to castaneous, moderately large, each eye with the subapical seta; ocular index 3.55-4.63; rostrum yellowish, reaching mid coxae; ocelli absent; antennae pale brown, length of antenna! segments: I 0.21 -0.28, II 0.25-0.30, IIJ 0.33-0.34, TV 0.37-0.39, V 0.48-0.51.

Pronotum castaneous to dark brown, shining, 1.88-2.12 times broader than long, its disc with small punctures, anterior margin concave, each lateral margin with a row of 3-4 submarginal setigerous punctures bearing hair-like setae; posterior margin straight; propleuron brown, shining, its depression with small punctures.

Scutellum triangular, 1.16-1.21 times longer than wide, scutellar disc with small, shallow punctures; mesocorium shallowly punctured, punctures medium-sized; clavo-corial suture absent or hardly visible; costa separated from exocorium in its basal two thirds, without or with a single setigerous puncture; membrane pale brown, small, flap-like, reaching the tip of abdomen.

Metapleural evaporatorium moderately large, peritreme elongated.

Legs pale brown to castaneous, fernora with brown hairs, tibiae straight bearing short brown or blackish brown spines, tarsi yellowish brown.
