description: <i>Polyplectropus jalan</i>, new species Figures 38–40 <b>Diagnosis:</b> This species is most similar to <i>P. simei</i> Malicky from Brunei and Sabah in having downward curving cerci and gonopods. In <i>P. jalan</i>, new species, the cerci have a mesal, subapical, vertically directed lobe, and the gonopods are accompanied by an excavated mesal surface, lacking in <i>P. simei</i>. The setose, subphallic sclerite is only slightly excised medioapically. <b>Description:</b> Male. Body uniformly brown. Maxillary palp formula (I,II)-IV-III-V, 3rd segment of each maxillary palp originating subapically on lateral face of segment 2, producing mesoapical cushion on segment 2. Forewing length 5.8 mm; each with discoidal cell closed, median cell open. Hind wings each with discoidal cell open. Forewings each with apical forks 1, 2, 3, 4 and 5 present; hind wings each with apical forks 2 and 5 present. Male genitalia. Tergite VIII produced; posteror mid-dorsal area covered with short pegs of microtrichia; membranous, almost hyaline short roof present over the phallic apparatus, may represent rudimentary segment X. Sclerotized sternite IX nearly triangular in lateral view (Fig. 38), with vertical dorsoapical elongation; narrow, parallel-sided, vertically directed, partly sclerotized tergite IX continuous with sternite IX, meeting on each side at fulcrum with cerci and paraproctal complex. Cerci elongate, clavate, slightly curving ventrad, each with vertically directed, hook-like, mesal lobe. Paraproctal complexes fused with cerci. Dorsal, sclerotized spine-like paraproctal processes straight, horizontal; recurving from bulbous base of paraproctal body; distal half supplied with 3 ventral protuberances; paraproctal sub-phallic sclerite very broad, slightly excised at middle. Gonopods complex (Fig. 39), with lateral part curving downward, setose; apically broad and rounded, each with large ventromesal excavation in lateral view and with 2 small teeth visible in ventral view. Phallic apparatus (Fig. 40) located dorsally in genitalia, guided by pair of dorsal paraproctal processes and paraproctal subphallic sclerite; phallic apparatus nearly in-discernible, comprising tube-like sclerotized phallotheca and membranous endotheca or endophallus; without clearly visible sclerites inside. <b>Holotype male: MALAYSIA: Sabah:</b> Tawau: Maliau Basin, Nepenthes Camp, 800 m, Jalan Babi, Heath Forest, 4 ° 43 ’ 55.1 ’’ N, 116 ° 53 ’ 7.9 ’’ E, 1048 m, 8.xii.–14.xii.2007, Canopy Malaise Trap [B.
