Nesoselandria nigroalata sp. n. (Figs 3, 18) Head dark blackish brown; clypeus whitish brown, supraclypeal and interantennal area brown, apical half of mandibles white. Head finely, shallowly, densely and uniformly punctured, shining. OOL:POL:OCL = 14:9:7. Diameter of front ocellus : length of genae = 5:2. Eyes large, temples very short and contracted behind eyes. Genae very narrow. Head without occipital carina. Postocellar furrows short and clear. No frontal area defined. Horizontal furrow above the antennae. Clypeus widely but slightly emarginated. Antennae brown. Ratios of antennái segments = 5:6:26:18:16:9:7:6:6. Length of antenna : length of costa = 62:65. Thorax brown. Cenchri white. Legs brown. Tibiae and basitarsi white with brown apical ring. Wings moderately infuscate, venation and stigma brown. Costa strongly swollen at stigma. Lobes of mesonotum shallowly and sporadically punctured, shining. Scutellum nearly smooth and shining with only few shallow punctures. Mesoscutellar appendage, postscutellum and mesopleuron smooth and shining. Head and thorax covered with short, whitish and moderately dense pubescence about 1/3-1/2 times as long as the diameter of front ocellus. Length of cenchrus : distance between the two cenchri = 12:7. Ratios of hind tarsal segments without claws = 25:8:6:4:8. Length of inner hind tibial spur : length of hind basitarsus = 9:25. Claws with well developed basal lobe and with subapical teeth smaller than the apical (Fig. 18). Abdomen entirely light brown. Abdominal tergites shining with shallow surface sculpture. Cerci small, sawsheath hardly seen from above (Fig. 3). Holotype: female: "Malaysia: Sabah, Sipitang, Mendolong, T3AV5. 2.111.1989. Leg. S. Adebratt". Paratypes: 19 females from the same locality: 1 female, 24.02.1989; 3 females, 02.03.1989; 5 females, 08.03.1989; 3 females, 14.03.1989; 1 female, 17.03.1989; 4 females, 31.03.1989; 1 female, 03.05.1989; 1 female, 13.05.1989. Types are deposited in the collection of the Zoological Institue of the Lund University. The new species is very similar to Nesoselandria albicornis (Forsius, 1929). Nesoselandria albicornis (Forsius, 1929) has lst-2nd antennái segments and basal half of 3rd segment brown, apical half of 3rd, and 4th-6th segments white, 7th-9th segments black. Abdominal sternites, except the last one, legs and tegulae entirely white. The new species has antennae entirely dark brown. Abdominal sternites like tergites and tegulae brown. Legs brown and white as described above. The other related species is Nesoselandria rufiventris Rohwer, 1915. N rufiventris Rohwer, 1915 has black thorax, fulvous abdomen and legs while the new species has brown thorax, light brown abdomen and legs richly coloured with white.
