( Figs 1B , 2I ) Material examined. 1 ♀ , ‘ NEPAL (prov. Bagmati ), Phuchauki nr. Kathmandu , 2300 m , 1.0V.81, I. Löbl’ ( MHNG ) . Description. Male. Unknown. Female ( Fig. 1B ). Body moderately elongate, length (combined length of head, pronotum, elytra and abdomen) 2.26 mm ; color uniformly red-brown, tarsi and palpomeres lighter; dorsum finely punctate. Head lengthily and bluntly triangular, length from anterior margin of clypeus to head base 0.51 mm , width across eyes 0.36 mm ; vertexal foveae at level of posterior margin of eyes; frons dilated apically, longitudinally and smoothly impressed between antennal tubercles; postocular margins rounded, with dense setae on each side; eyes small, hemispherical in lateral view, each composed of approximately 15 facets. Maxillary palpus ( Fig. 2H ) elongate, palpomere 4 with slightly sinuate lateral margin; length/width of palpomere 3 0.05/ 0.15 mm , palpomere 4 0.07/ 0.28 mm . Antennae elongate, length 2.31 mm ; antennomere 1 (scape) larger than 2 (pedicel), shorter than antennomeres 2 and 3 combined, antennomere 2 slightly broader than 3, antennomeres 3–8 of similar width, successively shorter, antennomere 9–11forming distinct club ( Fig. 2C ), antennomere 9 much larger than 8, elongate, antennomere 10 similar to antennomere 9 in size, antennomere 11 slightly shorter than 9 and 10 combined, suboval, widest at middle. FIGURE 2. Diagnostic characters of Klimaszewskia species (A–G. K . punctata sp. nov. H, I. K . sp.). A. Head and pronotum. B, H. Left maxillary palpus. C. Antennomeres 8–11. D. Meso- and metaventrite. E–G. Aedeagus, in lateral (E), and ventral (F, G) view. Scale bars: 0.2 mm in A, C, D; 0.1 mm in B, E–I. Pronotum subglobose, approximately as long as wide, length along midline 0.46 mm , maximum width 0.44 mm , with slightly arcuate anterior and posterior margin, sides rounded at middle, then narrowing toward apex and subparallel in basal two-fifths. Elytra subtriangular, much wider than long, length along suture 0.53 mm , maximum width 0.86 mm , shortened and strongly constricted at base, discal area with fine punctures, sides with long, dense hairs. Mesoventrite strongly transverse, with thin admesal ridges; mesoventral process with truncate apex. Metaventrite also transverse, with broad posterior intercoxal process, posterior margin of process broadly impressed at middle. Legs elongate, simple. Lengths of pro-, meso- and metatarsomeres 1–3: 0.04, 0.16, 0.17 mm ; 0.04, 0.18, 0.16 mm ; 0.05, 0.21, 0.18 mm . Abdomen wider than long, widest at sides of tergite 1 (IV), length along midline 0.76 mm , maximum width 0.94 mm ; tergite 1 (IV) 2.17 times as long as tergite 2 (V), lacking carinae. Genital complex ( Fig. 2I ) symmetric, transverse, 0.21 mm wide, moderately sclerotized. Distribution. Nepal : Bagmati . Comments. This female has an identical foveal pattern as of K . punctata sp. nov. , the elongate fourth maxillary palpomere is broadest at basal 1/3, the pronotum has a distinct antebasal sulcus, and the first visible tergite is longest. Collectively, these characters place this specimen in the newly defined Klimaszewskia . The single female apparently belongs to a different species according to the followings: 1) the body size is much larger than that of K . punctata sp. nov. (2.26 vs. 1.54 mm ), 2) the maxillary palpomere 4 is slightly sinuate on the lateral margin, and 3) the elytral disc is finely punctate.
