CENTROMERIA MELICHARI View in CoL SP. NOV.

FIGS 2H View Figure 2 , 21A – K View Figure 21

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 View Figure 21 ). 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 View Figure 21 ); lateral carinae moderately constricted and moderately upturned in front of eyes ( Fig. 21A View Figure 21 ). 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 View Figure 21 ). Gonostyles ( Fig. 21E View Figure 21 ) relatively small, upper process large and stout, obtuse apically. Aedeagus ( Fig. 6G – I View Figure 6 ) relatively small, endosomal processes extended posteriorly and curved dorsoanteriorly, apex distinctly inflated and bulbous ( Fig. 21G View Figure 21 ); 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 View Figure 21 ). Segment X large, projecting at an angle on each side; apical ventral margin projecting a triangular process ( Fig. 21E View Figure 21 ), in dorsal view with ratio of length to width near middle about 1.3: 1 ( Fig. 21D View Figure 21 ).

Distribution. Philippines (N. Palawan).
