Merkl, O.: Novelties of Sivacrypticus Kaszab, 1964 and Enneboeus Waterhouse, 1878 (Coleoptera, Archeocrypticidae)

Head finely and densely rugulose-punctate; antennae surpassing middle of pronotum. — Pronotum strongly transverse, widest at base; sides parallel in basal 1/3, then arcuately tapering; lateral margination strongly attenuating posteriorly; apex deeply emarginate; base distinctly bisinuate ; anterolateral angles acute in dorsal view ; posterolateral angles rectangular ; surface evenly convex, densely rugulose-punctate, weakly shining. — Elytra subparallel-sided ; with 9 regular rows of punctures and a short scutellary striola; 9th row running immediately near lateral margin; rows vanishing before apex; striai punctures rather coarse, separated by a distance equal to diameter of a puncture; intervals nearly flat, alutaceous. — Legs short and rather wide; femora more or less swollen; tibiae with outer edge straight, apex obliquely truncate. rf : Segment I of fore tarsi distinctly widened; tibiae broader; hind femora much more dilated distally, with inner edge concave; last abdominal sternite widely and deeply emarginate (Fig. 7); pygidium: Fig. 6; tegmen: Figs 2-3; penis with duct sclerite: Fig. 4; spicular fork: Fig. 5. 9 : Segment I of fore tarsi normal; tibiae narrower; hind femora not conspicuously dilated, with inner edge straight; last abdominal sternite weakly emarginate. Type material — Holotype, rf, labelled as follows: Manilla, P. I. Feb.

—Mar. 1912 | Exam Thaxter | Holotypus rf Sivacrypticus philippinus Merkl, 1988 [red]. Deposited in MCZC. — Paratypes (total 96 specimens) : labelled as holotype (32;/cf, 30 $ $, MCZC; Urfçf, 10 9 $, HNHM) Philippines, Manila, 1912, R. Thaxter? (60V > 3 9 9, MCZC; Irf, 19, HNHM). Remarks — Externally, this new species is somewhat reminiscent of Sivacrypticus greensladei KASZAB, 1984 (described from South Australia) on account of the coarse punctures arranged to rows on the elytra. Amongst the Indo-Malayan species, S. taiwanicus KASZAB, 1964 (described from Taiwan) has also punctural rows on the elytra. These three species differ from each other in the characters summarized in Table 1. Members of Sivacrypticus are known to occur in the Afrotropical Realm (KASZAB 1979), in southern Asia, including India, Pakistan, Nepal, Sri Lanka, Vietnam (KASZAB 1979), Thailand (KASZAB 1981) as well as in South Australia (KASZAB 1984). S. philippinus sp. n. is the first archeocrypticid known from the Philippines. Table 1.
