CENTROMERIA MACULATA SP. NOV.

FIGS 2G , 20A – J

Type specimens. Holotype: ♂, Malaysia, Borneo (Brit. N.), Sandakan Bay ( SW), Sapagaya Lumber, Camp, 2 – 20 m a.s.l., 5.xi.1957, J.L. Gressitt ( BPBM). Etymology. This new species name is derived from the Latin ‘ maculatus ’, referring to its tegmina with a large fuscous spot at apex.

Diagnosis. The new species is similar to C. nigroapicata , but can be distinguished from the latter by the shorter cephalic process and the differences of male genitalia and segment X.

Description. BL, ♂ 14.6 mm; HL, ♂ 1.9 mm; HW, ♂ 1.6 mm; TL, ♂ 11.6 mm.

Cephalic process in lateral view distinctly short, as long as length from anterior margins of eyes to posterior margin of vertex; more or less upturned in front of eyes and ascending at no more than 10° ( Fig. 20B ). Vertex relatively broad, posterior margin nearly as wide as transverse diameter of eyes; in dorsal view ratio of length to width between eyes about 2.7: 1 ( Fig. 20A ); lateral carinae moderately constricted and moderately curved upwards in front of eyes ( Fig. 20A ). Tegmina as Fig. 20D , with a large fuscous macula at apical one-fifth. Fore femora with a minute spine near apex; hind tibiae with six lateral spines; hind tarsomeres I with nine apical teeth and tarsomeres II with nine apical teeth.

Male genitalia with pygofer in lateral view broad and high, with ratio of ventral to dorsal width about 3.8: 1; posterior process near subapex elongate, slen- der, and curved, acute apically ( Fig. 20F ). Gonostyles ( Fig. 20F ) with upper process large and stout, acute apically. Aedeagus ( Fig. 10H – J ) moderately large, endosomal processes bent anteriorly ( Fig. 20I ); phallobase sclerotized and pigmented at base, membranous and inflated apically, with one pair of ventrolateral lobes small, with a pair of ventral lobes large and long, directed posteriorly, without spines ( Fig. 20I, J ). Segment X large and stout, in lateral view basal and apical ventral margins projecting ventrally ( Fig. 20F ), in dorsal view with ratio of length to width near middle about 1.2: 1 ( Fig. 20E ).

Distribution. Malaysia (northern Borneo).
