Phylloclusia sternopleuralis sp. nov.

( Figs 4, 5 )

Type material. Holotype male ( BPBM 17241), Malaysia, Sabah, 19 km N of Kalabakan, forest camp, 60 m, 25. X. 1962, K. J. Kuncheria. Paratypes: 3, Ƥ, same locality as holotype, 19 and 20. X. 1962, K. J. Kuncheria.

Description. MALE. Very similar to Phylloclusia bivittata sp. nov., differing from it in the following points: face yellow, faintly brown-tinged at middle; two dark stripes on mesoscutum slightly broader than those of bivittata , always united with each other anteriorly, forming semicircular marking along anterior margin of scutum (about 1/2 as long as distance between anterior margin of scutum and transverse suture), each postsutural stripe split into two narrow stripes in anterior 2/3–3/4 of its length, with lateral branch not reaching transverse suture; katepisternum blackish brown on anterior half; katatergite slightly brown-tinged; mediotergite blackish brown except for yellow lateral margins; wing with apical brown marking more darkened, extending posteriorly to M1; three distal tarsomeres of fore leg slightly brown-tinged.

Frons 1.2 times as wide as eye; gena 1/11 as high as eye; wing 3.2–3.5 (3.2) mm long, r-m before middle of cell dm (15: 22). Genitalia: surstylus ( Figs 4, 5 ) with small protuberance at middle of inner side; cercus with 8–10 strong posterior setae; phallapodeme ( Fig. 4 ) 480 µm long; mesophallus almost as long as basiphallus, with sclerites entirely separated; distiphallus 410 µm long. Body length 3.8–4.0 (3.8) mm. Other characters quite similar to those of P. bivittata .

FEMALE. Differing from the male in the following points: anterior semicircular marking on mesoscutum larger, and postsutural stripes not split; scutellum entirely black; katepisternum brown on anterior 3/4 of pleural length; anatergite and katatergite distinctly brownish; mediotergite centrally brown; T6 and T7 yellow; ovipositor black at base but yellow distally; wing length 3.2 mm, body length 3.5 mm.

Distribution. Malaysia (Sabah).

Etymology. The specific name refers to the dark katepisternum (sternopleuron).
