of the tenth segment and confluent with the superior appendages, two segmented. The caudad-upward directed rod-like first part ends in an enlarged suture separating the second back curving part which is horizontally flattened. The second part ends in a black spine somehow separated from the second part by a recurving junction. Superior appendages with a broad attachment to the tenth segment, and with outcurving apex in dorsal aspect. Inferior appendages subqudrangular

, spatulate in lateral and tapering in ventral aspect Both the ventral and dorsal median margin supplied with small humps, basement of hairs. Phallic apparatus tube-like. Phallotheca with an unpaired dorsal sclerotized tapering rod. Aedeagus long, rod-like. According to the wing venation, the structure of the fifth and sixth abdominal segments, as well as to the structure of genitalia this species belongs to the Synagapetus subgenus, rudis group and mitis subgroup. More resemblances to A. desom Oláh described from Vietnam, but the upper pair of the tenth segment and the inferior appendages differ from those of all known species. I name this species in honour of Dr. Susan Lim Lee Hong from the University of Malaysia who was so helpful to organise my short collecting trip to the River Sungai Gombalc Holotype <J. Tributary of River Sungai Gombák, 25 km from Kuala Lumpur, Malaysia, 21.XII.1991. Leg. Oláh. Singled along a small tributary from shore vegetation situated in a dep, steep valley of the jungle. 1 â paratype same as holotype. Chimarra kuala sp. n. (Fig. 2) Male (in alcohol). General colour fuscous, abdomen lighter, head dark castaneous. Legs with light gray sclerites. Wing membrane fuscous, hyaline areas along the veins on anastomal, thyridial regions and on the arculus of the fore wing. Rs on fore wing not sinuous. Basal half of the veins enclosing discoidal cells strongly thickened. In hind wing Fi present, sessile. Male genitalia. Ninth segment produced into almost a parallel sided semiring in lateral aspect, posteroventral process small, triangular, about as long as wide basally. Tenth tergum with a pair of vertically enlarged mesal plates covered with radial patterns of filiform surface structure. Most heavily sclerotized along an S-form subdorsal rib and on the posteroventral corner forming spine-like ending. In dorsal view these plates end in a filiform dorsal and a horizontally enlarged spatulate ventral apex. Small preanal appendages apparently completely fused to lateral surface of tenth tergum. Clasper subtriangular in side view. Upper margin almost straight lower apical margin more or less concave. From beneath the clasper is incurved, the lower margin inturned on halfway and forming a rectangular heavily sclerotized lobe. Phallus tubular enclosing two stout black spines. According to the genital structure this small species is quite close to C. dulUensis Kimmins described from Sarawak, but the more elaborated and complex plates of the tenth tergum and the subtriangular clasper differ. The aedeagus has only one spine in C. dulitensis. The radial filiform surface structure on the tenth tergum is also lacking. I name this species to remember the beautiful capital of Malaysia. 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 situated in a deep, steep valley of the jungle. Drepanocentron malaya sp. n. (Fig. 3) Male (in alcohol). Length of forewing 4 mm. This slender caddisfly fuscous, only antennae, first tibiae and the second and third legs are lighter gray. Fuscous first leg
