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

(Figs 1-6)

Diagnosis

The new species is similar to C. madagascariensis in its clearly flattened costa, but can easily be separated from the latter by its smaller body (4.70-5.35 mm in length; C. madagascariensis - 6.85-7.45 mm in length), distinctly denser puncturation of the dorsal body surface ( Fig. I), the 3 rd antenna! segment longer than the 2 nd (the 3 rd segment is shorter than the 2 nd in C. madagascariensis ), and in the costa bearing no setigerous punctures (2 setigerous punctures are present on the costa of C. madagascariensis ).

Description

Body blackish brown to castaneous, 4.70-5.35 mm in length, 3.05-3.45 mm in width.

Head black or blackish brown, 0.78-0.82 mm in length; clypeus impunctate, slightly concealed by paraclypei, and without a subapical pair of setigerous punctures; paraclypei coarsely punctured, each submarginally with a row of 3-4 setigerous punctures bearing hair-like setae (some specimens have additionally a submarginal row of small, black spines); eyes brown, narrow, ocular index 4.01-5.68, each eye with the apical seta, ocelli absent; rostrum pale brown, reaching middle coxae; length of anntennal segments: I 0.27- 0.29, II 0.19-0.27, Ill 0.27-0.29, IV 0.32-0.37, V 0.46-0.51.

Pronotum about 2.12-2.25 times broader than long, black or blackish-brown, coarsely and densely punctured, median part of its disc shiny; anterior margin broadly concave; each lateral margin with a row of 4-5 submarginal setigerous punctures bearing long hair-like setae, posterior margin straight; propleuron brown, sparsely punctured in the depression.

Scutellum triangular, strongly narrowed apically, about 1.32- 1.33 times longer than wide, its disc coarsely and densely punctate with small, deep punctures of the same size; clavo-corial suture absent or hardly visible; mesocorium densely punctate; costa flattened, separated from the exocorium in its basal 2/3, bearing no setigerous punctures; membrane pale brown, small, almost triangular, reaching or almost reaching the tip of abdomen.

Metapleural evaporatorium moderately large, almost reaching lateral margins of metapleuron, peritreme elongated.

Legs yellowish brown, femora with numerous, brown hairs; tibiae straight, bearing short brown spines, tarsi brown.

Abdominal sterna convex, blackish brown, sparsely punctured. Female genital plates as in Fig. 5, spermatheca as in Fig. 6. Male paramere and aedeagus as in Figs 3-4; opening of genital capsule as in Fig. 2.
