CENTROMERIA MELICHARI SP. NOV.

FIGS 2H, 21A – K

Type specimens. Holotype: ♂, [ Philippines], N. Palawan, Binaluan , xi – xii.1913, G. Boettcher ( MMBC).

Paratype: 1♀, same as holotype ( MMBC) .

Etymology. The new species is named after Dr Leopold Melichar, excellent entomologist and expert in Hemiptera , who revised the world Dictyopharidae in 1912.

Diagnosis. The new species is similar to C. triangulata sp. nov., but can be distinguished from the latter by the endosomal processes of aedeagus with apex distinctly inflated and bulbous, and the phallobase with a pair of dorsal apical lobes. Description. BL, ♂ 14.6 mm; HL, ♂ 1.9 mm; HW, ♂ 1.6 mm; TL, ♂ 11.6 mm.

Cephalic process in lateral view elongate, distinctly longer than length from anterior margins of eyes to posterior margin of vertex; slightly upturned and ascending at about 10° ( Fig. 21B). Vertex relatively broad, posterior margin nearly as wide as transverse diameter of eyes; in dorsal view ratio of length to width between eyes about 3.4: 1 ( Fig. 21A); lateral carinae moderately constricted and moderately upturned in front of eyes ( Fig. 21A). Fore femora practically without a discernible spine at apex; hind tibiae with seven lateral spines; hind tarsomeres I with nine or ten apical teeth and tarsomeres II with 11 or 12 apical teeth.

Male genitalia with pygofer in lateral view broad and high, with ratio of ventral to dorsal width about 3.7: 1; posterior process near middle short and small, acute apically ( Fig. 21E). Gonostyles ( Fig. 21E) relatively small, upper process large and stout, obtuse apically. Aedeagus ( Fig. 6G – I) relatively small, endosomal processes extended posteriorly and curved dorsoanteriorly, apex distinctly inflated and bulbous ( Fig. 21G); phallobase sclerotized and pigmented at base, membranous and inflated apically, with one pair of small dorsal lobes between endosomal processes, and a pair of ventral lobes slender and thumb-like, directed posteriorly ( Fig. 21I). Segment X large, projecting at an angle on each side; apical ventral margin projecting a triangular process ( Fig. 21E), in dorsal view with ratio of length to width near middle about 1.3: 1 ( Fig. 21D).

Distribution. Philippines (N. Palawan).
