of metathorax (fig. 30). Colour red-brown or dark brown, elytra, meso-, metathorax darker, dark red-brown or brown, elytra at apical part and often suturai area lighter. Body 1.79 to 1.89 times longer than wide. Parameres very poorly longer than the central lobe of aedeagus (fig. 34). Length 1.5 to 1.8 mm. Nepal _ L. (Lederina) similis sp.n. 12(7) Axial depression of metathorax absent, its place being occupied by a more or less narrowly triangular flattened keel (figs. 26, 27). Body shorter, ca 1.67 to 1.84 times longer than wide (figs. 2, 3). 13(14) Smooth edging of axial very narrowly triangular flattened keel of metathorax reaching to first 1/4 to 1/5 of the length of metathorax, length being measured from hind margin of mesocoxae (fig. 26). Body broader, oval, 1.67 to 1.78 times longer than wide (fig. 3). Dorsum more or less dull. Aedeagus as depicted (fig. 31). Length 1.4 to 1.7 mm. Vietnam L. (Lederina) kaszabi sp .n . 14(13) Smooth edging of axial narrowly triangular flattened keel ending not farer than between first 1/3 and 1/4 of length of metathorax (fig. 27). Body more or less oblong-oval, 1.8 to 1.84 longer than wide (fig. 2). Dorsum more or less dull or slightly shining. Aedeagus as depicted (fig. 32). Length 1.3 to 1.6 mm. Vietnam L. (Lederina) topali sp.n. 15(6) Larger: 1.7 to 2.3 mm. Spurs of metatibiae shorter, unequal in length, longer of which usually reaching only apical third or quarter of tarsal joint 1 (figs. 23, 24). Abdominal sterna in males with rather broad axial depressions. Metasternum clearer punctured. Colour from red-brown to reddish-brown. Japanese species. (Unfortunately, L. lata is known only by females which have no axial depressions on abdominal sterna.) 16(17) Larger: 2.3 mm long. Body broad, 1.63 to 1.67 times longer than wide. Depression along middle of posterior part of metathorax wider and flatter (fig. 37). Abdominal sterna without depressions. Metatarsal joint 1 nearly straight (fig. 24). Elytra very finely and sparsely punctured (isthmus between punctures at anterior parts of elytra usually not less than 2.0 to 2.5 times larger than diameter of a puncture). Apices of elytra somewhat protruding, slightly apart, rounded separately. Body very convex, red-brown, dorsally very poorly shining, covered with very shin, decumbent, yellowish-grey pubescence. Japan (Kasiwagi) L. (Lederina) lata (Lewis)* 17(16) Smaller: 1.7 to 1.8 mm long. Body more slender, 1.75 to 1.85 times longer than wide. Depression along middle of posterior part of metathorax narrower, oblong-oval (fig. 39) or in form of a groove sharpened posteriad (fig. 38). Abdominal sterna with distinct axial depressions. Metatarsal joint 1 in L. foenilis (Lewis) distinctly curved (fig. 23). 18(19) Depression along middle of hinder part of metathorax oblong-oval, distinctly narrowing both anteriad and posteriad (fig. 39). Elytra very finely and rather sparsely punctured, isthmus between punctures at anterior part of elytra not less than twice as large as diameter of a puncture. Lateral parts of metathorax well and rather densely punctured (isthmus between punctures usually subequal to diameter of a puncture). Body ca. 1.84 times longer than wide, well transversely shagreen. Colour rusty-red, surface very poorly shining. Length 1.8 mm. Japan L. (Lederina) japonica Rtt. 19(18) Depression along middle of hinder part of metathorax more parallel-sided, groove-like, sharpened backward (fig. 38). Elytra rather finely, but still coarser punctured than in two previous species. Body ca. 1.75 to 1.85 times longer than wide. Metatarsal joint 1 distinctly curved (fig. 23). Colour red-brown, surface slightly shining. Length 1.7 to 1.85 mm. Japan L. (Lederina) foenilis (Lewis) 20(5) Antennái joint 3 much less than twice thinner and less than 2.5 times shorter than 2nd (fig. 8). Antennái club very poorly demarcated, 4-jointed (fig. 8). Metepisterna considerably broader, roundly narrowing backward (fig. 18), ca. 2,7 to 3.0 times longer than wide. Metathorax dull, with a clear isodiametric microsculpture consisting of rounded cells (fig. 18) and very sparsely and finely superficially punctured. Depression along middle of hinder * Females of L. foenilis (Lewis) and L. japonica Rtt. rest unknown. Possibly L. lata described by two females belongs in fact to either of them To solve the matter, new materials from Japan should be studied. ** Unfortunately on the holotype of L- japonica , wanting both metatarsi, the form of their joint 1 could not be detected.
