Type materied - Holotype (male): Laos, Vientiane Prov., Vang Vieng, near Poukham Cave, 300 m, 21 March 1998. (HNHM). Paratypes: same locality, 2 specimens (HNHM, LM). Remarks - The very rough sculpture of elytra is characteristic; among Dercetina GRESSITT et KlMOTO, 1963 only D. travancorensis MAULIK, 1936 from South India has sculpture of same type, but in latter species head and antennae are fulvous, elytra with four ridges, including two of them near suture; proportions of antennae are also different. Zipangia merkli sp. n. (Alticinae) (Fig. 12) Description - Fulvous with antennái segments 3-11 pitch brown to black. Head impunctate, shining. Frontal tubercles rounded-triangular, poorly delimited on sides, frontal groove deep and sharp, feebly arcuate. Frons almost twice as wide as eye diameter. Antennae reach middle of elytra, with apical segments slightly thickened, proportions of segments are as 9-5-6-5-7-6-7-7-6-7-9, prcapical segments about 1.5 times as long as wide. Prothorax 1.6-1.7 times as wide as long, lateral margins feebly rounded, sharply oblique near anterior angles, surface shining, strongly, but not very densely punctate, with shallow basal groove, more deep in middle. Elytra 1.3 times as long as wide, without basal convexity, shining, strongly punctate. Tarsal segment 1 of fore legs moderately widened in male. Aedeagus as in Fig. 12. Length 3.3-3.9 mm. Type material - Holotype (male): Laos, Champassak Prov., Dong Hua Xao NBCA, 2 km S of Nong Luang village, the bank of Touay-Guai stream, 15°4'N, 106°13'E, 800 m, 1-5 April 1998. (HNHM). Paratypes: same locality, 5 ex. (HNHM, 2 ex. - LM). Remarks - Near Z. infuscaticornis SCHERER, 1979, but the latter is smaller (2.3-2.7 mm), with 4th antennái segment 1.5 times as long as 3rd, preapical segments not less than twice as long as wide and aedeagus of other form. Aphthonomorpha laosensis sp. n. (Alticinae) (Fig. 13) Description - Black; head, basal segments of antennae, prothorax, legs except hind femora and abdomen, especially behind fulvous. Body elongate ovate. Head impunctate, frontal tubercles indistinct, ocular grooves sharp. Antennae reach anterior third of elytra, segment 3 as long as 2 and 4, 5th a little longer than 4 and subequal to the next segments. Prothorax 1.6 times as wide as long, side margins practically straight and parallel, sharply oblique before anterior angles, surface deeply punctate. Elytra 1.4 times as long as wide, with very feeble basal convexity, with regular rows of strong punctures except suturai area where they are entirely confused. First abdominal segment without ridges on base. Hind tarsus with segment 1 very long, about 0.6 of tibia length. Aedeagus (Fig. 13) with deep and sharply delimited longitudinal groove on underside. Length 3-3.5 mm.
