lacking, crossvein SR-M just visible. Bifurcation SR rather basal, bifurcation M very apical. F5 present Black scales along Rj and pink scales along SR and on the anal region. Male genitalia. Ninth tergum concave posteriad with central broadening anteriad in dorsal aspect. Joining to superior appendages with long and slender anterolateral apodemes. Ninth sternum tapering into long anterolateral apodemes. Its apical process triangular caudad. Distal ventral lobe of tenth segment with two pairs of darkened teeth on the lateral border, apex of segment ending in a pair of similar dark almost touching teeth. Fourth pair of teeth located on the dorsum of tenth segment just behind of ninth tergum and asymmetric Superior appendages end bulbous and narrowing midway. Inferior appendages with thin filiform distal part and serrated ventral and mesal surface on the middle portion, around the basement of the fused second segment In ventral aspect well developed spine demarcates the basal inner corner of the second joint Phallic apparatus forms a long simple tube with erectile, membraneous aedeagus ending in a pair of terminal, slightly sclerotized plates. Three groups of less visible spine arrangement located around middle of membraneous part. According to the hind wing venation and genital structure this species belongs to druhyu group but differs from all the described species both in venation and genital structure. Holotype 6. Tributary of River Sungai Gombák, 25 km from Kuala Lumpur, Malaysia, 21.XII. 1991. Leg. Oláh. Singled along a small tributary from shore vegetation in a deep, steep valley of the jungle. Drepanocentron limorum sp. n. (Fig. 4) Male (in alcohol). Length of fore wing 4 mm. General colour fuscous, but all legs are light gray. The modified apical spur on hind leg gradually tapering and almost as long as the length of basal tarsomere. All the described species in the genus have much longer basal tarsomere than the length of their modified spurs. Fore wing uniformly fuscous without white marks. Fore wing venation with Sc ending on C, discoidal cell almost twice longer than thyridial cell. ,4; andA2 present Hind wing venation more modified. Sc short. Bifurcation SR around middle of hind wing close to the bifurcation M. Crosveins Ri-SR and SR-M close to the bifurcation SR. F5 present. Black scales between Ri and SR and pink scales between SR and M. Male genitalia. Ninth tergum convex posteriad with long mediadorsal plate anteriad. This plate almost as long as the slender anterolateral apodeme joining to superior appendages. Ninth sternum tapering into long anterolateral apodeme without any angle with slight upwarding. Its ventroapical process with narrowing and excised apex. Tenth segment widely separated distally with one pair of blackened teeth on each lateral dorsum. One pair of longer blackened teeth located below the ninth tergum and characteristically asymmetric. Superior appendages end bulbous, almost gradually narrowing basad. Inferior appendages with serrate basement of the fused second joint Location of inner basal corner with spine shows more short fused first join. Phallic apparatus forms a long tube with erectile membranous second half of aedeagus without visible arrangements of spines or sclerotized plates. According to hind wing venation and the genital structure this species belongs to druhyu group but differs from all the described species. I name this black, slender animal to remember Dr. Lim-s family, young son, dauther and her husband. Holotype 6. Tributary of River Sungai Gombák, 25 km from Kuala Lumpur, Malaysia, 21.XII.1991. Leg.
