Ślipiński, S. A.: A rewiew of the Cerylonidae (Coleoptera) from New Guinea

Cautomus SHARP, 1885 This genus is represented in New Guinea by a single species. The 10-segmented antenna and its 4-segmented tarsi place it within the subgenus Leptoxycheilus BESUCHET. Cautomus (Leptoxycheilus) minutus sp. n. Body reddish brown, convex, dorsal surface sparsely pubescent, shiny. — Head : anterior clypeal margin scarcely emarginate medially, surface somewhat convex, sculptured; frons and vertex flat with same sculpture as on clypeus; eyes black, fully developed, coarsely facetted; antenna 10segmented with scape twice as long as wide, club composed of two segments. — Pronotum transverse (11:22); anterior margin straight, not bordered; anterior angles broadly rounded, not prominent; lateral margins arcuate, converging basally and anteriorly, widely and entirely bordered; disk convex, not distinctly punctured, sculptured only as head; laterally pronotum with 3 or 4 squamiform setae. Scutellum triangular, smooth, rounded apically. — Elytra oval (22:20) with the maximum width near the base; fore margin without tubercles, smooth; each elytron with 12 rows of punctures; elytral punctures absent apically; intervals flat or evenly convex, impunctate; squamiform setae situated on 2, 4, 6, 8, 10, 12 and 13 intervals. — Ventral side: surface coarsely punctured; fore coxal cavities open behind; prosternai process parallel-sided, rounded apically, without median impression, its surface coarsely punctured; metasternum and ventrites punctured, punctures 1 diameter apart. — Legs: tibia long, expanded apically; tarsi 4-segmented. — Length 0.9 mm, width 0.5 mm. Material examined — Holotype, sex not determined, New Guinea, Stephansort, Astrolabe Bay, BÍRÓ 1900 (TMB). — Two paratypes: 1, with same data as holotype; 2, New Guinea (SE) Kiunga, 23 VII-2 VIII 1969 (No. NGK-B. 29) DR. J. BALOGH. Notes —Closely related to C. (L.) philippinensis BESUCHET from Mindanao, but the anterior pronotal margin is unbordered, pronotal disk sculptured (not punctured) and elytral base without small tubercles. Cerylon LATREILLE, 1802 Nine species of Cerylonidae from New Guinea correspond perfectly with the definition of the genus Cerylon LATR., given by SEN GUPTA & CROWSON (1973) and may be considered as members of that controversial genus. They are easily distinguished by the following key: 1 Dorsal surface densely pubescent; pronotal borders finely denticulate (Fig. 1) C. baloghi sp. n. — Dorsal surface sparsely pubescent or smooth 2 2 Eyes large, fully developed 4 — Eyes small, reduced to 3 or 12 facets 3 3 Eyes composed of 12 facets; pronotum slightly narrowing basally; each elytron with 7 rows of punctures C. cerylonoides (HEINZE) — Eyes composed of 3 facets; pronotum more narrowing basally; each elytron with 5 fully developed rows of punctures C. ocellatus sp. n. 4 Pronotum with large sublateral impressions on each side (Figs. 2, 5) 5 — Pronotal laterosubbasal impressions small (Fig. 3) or absent 6 5 Pronotum with deep fovea near anterior angles (Fig. 5) C. papuanum HEINZE — Pronotum without fovea near anterior angles (Fig. 2) C. biroi HEINZE 6 Sublateral impressions on pronotum small, but distinct (Fig. 3); body strongly flattened C. braminum MÖTSCH. — Pronotum without sublateral impressions; body more convex 7 7 Pronotal disk strongly convex; length less than 1.6 mm C. angoramus sp. n. — Pronotal disk more flattened; total length more than 2.1 mm 8 8 Pronotum strongly narrowing basally, widest near anterior third (Fig. 7) C. kaszabi sp. n. — Pronotum less narowing basally, widest at middle (Fig. 10) C. solomoni sp. n.
