Sulabanus ulci sp. nov.

(Figs. 17–18)

Type material. Holotype. Male. S. Sulawesi, 25 km E Mamasa, 1100 m, 119.28.39E, 3.02.10S, 22-24 July 1999. Bolm lgt. 16 paratypes. 11 males, 3 females, same locality data as the holotype; 1 male, S. Sulawesi, 8 km W Mamasa (Nepe), 119.20.32E, 2.56.13S, 29-31 June 2001, Bolm lgt.; 1 male, S. Sulawesi, 25 km E Mamasa (Kalama), 119.28.39E, 3.02.10S, 1-3 July 2001, Bolm lgt. ( LMBC).

Differential diagnosis. Sulabanus ulci resembles all black coloured species of the genus Sulabanus and according to the shape of its male genitalia it belongs to the S. mamasensis group as defined above. In the S. mamasensis group, S. ulci , as well as S. barclayi and S. nigrocordatus , have elytra without the yellow transverse band on the humeral third. The male genitalia of S. ulci are characterized by a short apical part of the phallus (the slender part represents less than 30 percent of the length of the phallus in S. ulci and more than 30 percent in S. nigrocordatus and S. barclayi ) and the widest part is gradually narrowing toward the apex (Figs. 17–18). Other black coloured species in the S. mamasensis group differ also in the size of eyes. S. ulci has the lowest ratio between interocular distance and maximum eye diameter in lateral view (1.30 compared with 1.35-1.45 in similarly coloured species in the S. mamasensis group).

FIGURES 15–31. Male genitalia. 15–16 Sulabanus mamasensis ; 17–18 S. ulci ; 19–20 S. minor ; 21–22 S. cordatus ; 23– 24 S. barclayi ; 25–26 S. nigricordatus ; 27–28 S. pendolensis ; 29–30 S. lalui ; 31 S. rufomarginatus Scale 0.5 mm (Figs. 15 –31).

Description. Body dark brown to black, without any bright colored part of body. Head partly hidden by pronotum. Minimum frontal eye distance 1.30 times maximum eye diameter. Pronotum flat, 1.15 times wider that long. Elytra parallel–sided, 3.3 times longer than width at humeri. Male genitalia with widened part of phallus in apical third, apex of phallus symmetrical (Figs. 17–18).

Measurements. BL 6.9 mm, HW 1.65 mm, PL 1.16 mm, PW 1.34 mm, Ediam 0.3 mm, Edist 0.39 mm, EL 5.5 mm.

Distribution. Sulawesi, known only from the type locality in the Mamasa valley in southwestern Sulawesi.

Etymology. This species is dedicated to Prof. Otto Ulc (Vestal, N. Y., USA).
