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

Body long-oval, flattened; dorsal surface piceous-brown,glabrous,shiny. — Head : anterior clypeal margin widely, scarcely emarginate medially, surface flattened, impunctate; frontoclypeal suture absent; frons and vertex flat, punctured, vertical punctures larger than frontal, separated by 1-1.3 diameters; eyes large, coarsely facetted, slightly prominent; antenna 10-segmented with an oval club, latter as long as antennái segments VII-1X together, segment II as long as wide, segment III twice as long as wide, segments IV-VI1I subquadrate, IX rounded, slightly transverse. — Pronotum transverse (27:35), widest at one third from anterior angles; anterior margin scarcely, widely emarginate medially, not bordered; anterior angles somewhat prominent, acute, posterior ones obtuse, not prominent; lateral margins arcuate, narrowly, entirely bordered; pronotal base almost straight, not bordered; disk coarsely punctured, punctures larger than on vertex, 1-1.5 diameters apart. Scutellum triangular, smooth. — Elytra long (61:40), 1.5 times as long as their maximum combined width, which is at one third from bases; each elytron with 6 fully developed rows of punctures, 7th row reduced to 4-5 punctures at base; elytral striae slightly grooved basally and absent apically, intervals between striae wide, flat, impunctate. — Legs: fore and middletibia with apical tooth (Figs. 8-9), tarsi 4-segmented, segment I lobed below. — Ventral side : fore coxal cavities closed behind; prosternai process narrow, slightly widened apically, its anterior margin straight, surface flat, sculptured; meso- and metasternum sparsely punctured; ventrites impunctate. — Length 2.2 mm, width 1.1 mm. Holotype : New Guinea (SE), Mt. Giluwe, Tambul, 28 VIII 1969, (No. NGG-M. 16) DR. J. BALOGH (TMB). Note —• This interesting species can be distinguished from all known species of this genus by its form of fore and middle tibia and also by its lobed tarsal segment T. Cerylon solomoni sp. n. (Fig. 10) Body long-oval, somewhat depressed, dorsal surface reddish-brown, shiny, practically glabrous. — Head : anterior clypeal margin scarcely emarginate medially, surface flat, sparsely punctured; frons and vertex convex, regularly and coarsely punctured, round punctures separated by less than 0.5 diameter; antenna 10-segmented, segments I

11 longer than wide, segments IV, V subquadrate, VI-VIII progressively wider and longer, IX rounded, X forming a large club; eyes large, normally facetted. — Pronotum transverse (40:49), widest at middle, converging forwards and backwards; anterior margin scarcely emarginate medially, not bordered ; anterior angles rounded, finely prominent, posterior ones more prominent; lateral margins arcuate, finely and entirely bordered; pronotal base unbordered, sinuate at posterior angles. Scutellum transverse, triangular, smooth. — Elytra long (80:53) with maximum width at middle, narrowing basally and apically; each elytron with 7 fully developed rows of punctures, striai punctures large, separated by 1 diameter; intervals between striae flat, impunctate. — Ventral side: prosternai process widened apicad, dorsal surface smooth; mesosternum and metasternum irregulary, coarsely punctured; ventrites with 2-3 rows of punctures, the last with emargination apically. — Legs short, femora and tibia wide; foretibia with small tooth apically; tarsi 4-segmented with I segment lobed below.

— Length 3.1 mm, width 1.2 mm. Holotype : Solomon Is., Wainoni, W. M. MANN (MCZ). — Four paratypes : 3, New Guinea, Erima, Astrolabe Bai, 1869, BÍRÓ (TMB); 1, New Guinea. Wau, 15 XII 78, N. 317, L. DEHARVEUG (MHNG). Cerylonopsis HEINZE, 1944 HEINZE originally described Cerylonopsis as a subgenus in Cerylon LATR., it was SEN GUPTA & CROWSON (1973, p. 432) who raised it to the genus rank. Only three species are known, two of them occur in New Guinea.
