description: Klimaszewskia punctata Yin & Zhang, sp. nov.
(Figs 1A, 2A–G)
Type material. HOLOTYPE: INDONESIA: ♂, two labels: ‘INDONESIA: W Java, Situ Lembang, ca. 1500 m, 15 km N Bandung (note: ca. 6°44′S, 107°35′E), lg. Schuh, 7. 8. 1994 / Holotype ♂, Klimaszewskia punctata sp. nov., det. Yin & Zhang 2021, MHNG (red label)’ (MHNG).
Diagnosis. As for the genus, plus body length 1.54 mm; lateral margin of maxillary palpomere 4 almost straight; elytral disc with large, sparse punctures; and ventrally strongly curved aedeagus with two pieces of endophallic sclerites.
Description. Male (Fig. 1A). Body generally moderately elongate, length (combined length of head, pronotum, elytra and abdomen) 1.54 mm; color uniformly reddish-brown, tarsi and palpomeres lighter; dorsal surface of head, pronotum and abdomen finely punctate, elytra with larger punctures.
Head (Figs 1A, 2A) lengthily and bluntly triangular, length from anterior margin of clypeus to head base 0.34 mm, width across eyes 0.28 mm; vertexal foveae at level of midline of eyes; frons dilated apically, longitudinally and smoothly impressed between antennal tubercles; postocular margins rounded, with dense setae on each side; eyes large, prominent, reniform in lateral view, each composed of approximately 35 facets. Maxillary palpus (Fig. 2B) elongate, palpomere 4 with almost straight lateral margin; length/width of palpomere 2 0.04/ 0.17 mm, palpomere 3 0.03/ 0.11 mm, palpomere 4 0.05/ 0.23 mm. Antennae elongate (Fig. 1A), length 0.85 mm; antennomere 1 (scape) larger than 2 (pedicel), shorter than antennomere 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, approximately as long as wide, antennomere 10 moderately transverse and wider than antennomere 9, antennomere 11 longer than 9 and 10 combined, suboval, widest at basal 1/3.
Pronotum (Fig. 2A) subglobose, as long as wide, length along midline and maximum width 0.31 mm, with slightly sinuate anterior and arcuate posterior margin, sides rounded at middle, then narrowing toward apex and subparallel in basal two-fifths.
Elytra (Fig. 1A) much wider than long, length along suture 0.41 mm, maximum width 0.57 mm, discal area with sparse and large punctures, sides with long, dense hairs. Mesoventrite (Fig. 2D) strongly transverse, with thin admesal ridges extending from anterior margins of mesocoxal cavities to level of median mesoventral foveae; mesoventral process with truncate apex. Metaventrite also transverse, with broad posterior intercoxal process, posterior margin of process broadly impressed at middle.
Legs elongate, lacking distinct modifications; mesotibia with small apical tubercle. Lengths of pro-, meso- and metatarsomeres 1–3: 0.04, 0.1, 0.11 mm; 0.04, 0.11, 0.11 mm; 0.05, 0.14, 0.12 mm.
Abdomen wider than long, widest at sides of tergite 1 (IV), length along midline 0.48 mm, maximum width 0.57 mm; tergite 1 (IV) 2.17 times as long as tergite 2 (V), lacking carinae.
Aedeagus (Fig. 2E–G) triangular in general form, length 0.21 mm, median lobe with broad, slightly asymmetric basal capsule, apical half strongly curved ventrally, narrowing apicad, forming rounded apex; endophallus composed of two pieces of moderately sclerotized plates; parameres reduced to fused, round membrane.
Female. Unknown.
Distribution. Indonesia: West Java.
Etymology. The specific epithet ‘ punctata ’ (adjective, meaning ‘punctuated, pointed’) refers to the roughly punctate elytral disc of the new species.
