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

( Figs 19-24)

Diagnosis

The new species is characterized by a set of the following characters: body shining, blackish brown, pronotum impunctate, scutellar disc coarsely punctured, each paraclypeus with 1 -3 submarginal sctigerous punctures bearing hair-like setae, lateral margin of pronotum with 4-5 submarginal setigerous punctures. The new species is allied to C. ernsti in its body size and the character of puncturation, but differs from the latter in a number of submarginal setigerous punctures on the head (4-5 in C. ernsti , 1-3 in C. similis ) and the pronotum (5-6 in C. ernsti , 4-5 in C. similis ), as well as in the puncturation of scutellum (scutellar disc impunctate in C. ernsti , scutellar disc with sparse puncturation in C. similis ). The characters separating the new species from the others within the genus are presented in the key to species.

Description

Body castaneous to dark brown, medium sized (4.60-5.40 mm in length, 2.80-3.10 mm in width), dorsum weakly convex ( Fig. 19).

Head dark brown to black, shining, 0.78-0.88 mm in length; clypeus impunctate, slightly concealed by paraclypei, without a subapical pair of setigerous punctures; each paraclypeus with 1-2 (sporadically 3) setigerous punctures bearing hair-like seate; eyes red to pale brown, moderately large, each eye with the apical seta; ocular index 3.79-4.85; ocelli absent; rostrum pale brown, reaching middle coxae; I, II and III antenna! segments almost equal in length, length of antenna) segments in mm: I 0.25-0.29, II 0.25-0.30, III 0.26-0.32, IV 0.29-0.37, V 0.44-0.51.

Pronotum castaneous to dark brown, shining, impunctate, 2.0-2.l times broader than long, anterior margin concave; each lateral margin with a row of 4-5 submarginal setigerous punctures bearing hair-like setae; posterior margin straight; propleuron brown, bearing small punctures in the depression.

Scutellum triangular, l.36- 1.40 times longer than wide, its disc punctate, punctures medium sized, well-separated, puncturation of apical part denser than that of the basal part; mesocorium densely punctured with deep punctures, clavo-corial suture absent, costa convex, separated from exocorium in its basal two thirds and bearing no setigerous punctures (sporadically a single seta is present); membrane small, pale brown, reaching the tip of abdomen.

Legs pale brown to castaneous, femora with row of small, brown spines ventrally, tibiae straight, with short blackish brown spines; tarsi pale brown.

Abdominal sterna convex, castaneous to dark brown, coarsely punctured; male genitalia as in Figs 20-21; female genitalia as in Figs 23-24.
