CENTROMERIA CUSPIDATA SP. NOV.

FIGS 2B , 15A – I

Type specimens. Holotype: ♂, Philippines, Mindanao , Agusan, S. Francisco 10 km. SE, 12.xi.1959, L.W. Quate ( BPBM).

Etymology. This new species name is derived from the Latin ‘ cuspis ’, referring to its acuminate cephalic process.

Diagnosis. The new species is similar to C. deckerti sp. nov. in the longipennis clade, but can be distinguished from the latter by the phallobase with lateral lobes relatively shorter, without additional lobes. It may be separated from C. triangulata sp. nov. by the phallobase with lateral lobes much longer.

Description. BL, ♂ 18.2 mm; HL, 2.6 mm; HW, 1.7 mm; TL, 13.0 mm.

Cephalic process in lateral view relatively elongate, distinctly longer than length from anterior margins of eyes to posterior margin of vertex; moderately upturned and ascending at about 20° ( Fig. 15B ). Vertex relatively broad, posterior margin nearly as wide as transverse diameter of eyes; in dorsal view ratio of length to width between eyes about 3.5: 1 ( Fig. 15A ); lateral carinae moderately constricted and moderately upturned in front of eyes ( Fig. 15A ). Fore femora practically without 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 3.4: 1; posterior process near middle short and small, but stout and slightly curved, acute apically ( Fig. 15E ). Gonostyles ( Fig. 15E ) relatively small, more or less expanded towards apex, broadest subapically, apex bluntly rounded; upper process large and stout, obtuse apically. Aedeagus ( Fig. 6G – I ) moderately large, endosomal processes extended posteriorly and curved dorsoanteriorly ( Fig. 15G ); phallobase sclerotized and pigmented at base, membranous and inflated apically, with one pair of lateral lobes long and thumb-like, directed laterally, and one pair of ventral lobes longer and thumb-like, directed posteriorly. Segment X in dorsal view large and elongate, projecting an angle on each side; apical ventral margin projecting at a long triangular process ( Fig. 15E ), with ratio of length to width near middle about 1.6: 1 ( Fig. 15D ).

Distribution. Philippines (Mindanao).
