Kudakrumia malaenglek sp. nov.

( Figs 1–4 View FIGURES 1–7 , 13–14 View FIGURES 13–20 )

Diagnosis. Male. This new species is characterized by the following combination of characters: metapleuron and lateral propodeal face transverse striate dorsally and posteriorly, striae largely obliterated anteroventrally ( Fig. 2 View FIGURES 1–7 ); parapenial lobe of basiparamere apically slender, digitiform ( Fig. 13 View FIGURES 13–20 ); volsella and basiparamere ventrally long, clearly surpassing apex of penis valves ( Fig. 14 View FIGURES 13–20 ). Body length: 2.5–4 mm. Female. Unknown.

Description. Holotype male. Length: 3 mm. Coloration. Body black, mandible, antenna, tegula, and legs variegated orange and brown ( Figs 1, 3 View FIGURES 1–7 ). Body setae short dense silvery white, except T3–7 interspersed brown and silvery. Tibial spurs pale yellow-white. Head. Punctures small, dense. Eye seta length less than half DLO. Clypeus punctate and setose, convex, ventral margin rounded. Mandible tridentate. Antennal tubercles not connected by transverse carina. Antennal scrobe without dorsal carina. Ocelli moderate, OOD 3.0 × DLO; IOD 0.9 × DLO. Scape 1.6 × as long as wide, unicarinate. F1 1.1 × pedicel length; F2 1.3 × pedicel length. Mesosoma . Mesosoma with small dense punctures, except metapleuron evenly transverse striate dorsally and smooth ventrally, and lateral propodeal face with transverse striae. Notauli extending to anterior margin of mesoscutum; parapsidal lines about two-thirds mesoscutum length. Tegula with uniform punctures. Dorsal and lateral propodeal faces differentiated by carina. Legs. Procoxa unarmed. Metacoxa with short longitudinal carina dorsally. Wings. Forewing evenly setose, basically colorless, veins brown, except yellowish at base; second submarginal cell sessile with marginal cell, larger than third submarginal cell; marginal vein with four abscissae. Metasoma. Metasoma densely punctate; posteriorly and laterally with narrow sub-translucent brownish smooth margin. S1 basomedially with down-pointing tooth. S2 basomedially unarmed. T2 basally with transverse strip of thick longitudinal striae. T7 convex, posterior margin rounded. S8 without lateral processes, posterior margin rounded. Genitalia. Genitalia as in Figs 13–14 View FIGURES 13–20 . Dorsal parapenial lobe digitiform, volsella and ventral parapenial lobe long, clearly surpassing posterior margin of penis valves. Paramere dorsoventrally compressed, posterior apex rounded. Female. Unknown.

Type material. Holotype ♂: THAILAND, Saraburi, Mai Ngerm Mai Thong resort, 7 km NW Muak Lek, 14.711 oN 101.165 oE, 16–30.III.2019, Malaise trap, K.A. Williams, A.R. Chaves, S. Puttasok, R. Malee, K. Thoawan, N. Thaochan ( CSCA) . Paratypes: Same data as holotype: Malaise trap (25♂ CSCA, QSBG, RMNH); Yel- low flight intercept trap (1♂, CSCA) .

Distribution. Known from the type locality only.

Etymology. Derived from the Thai แมลงขนาดเล็ก, small insect. This is an allusion to the generic name Kudakrumia , which was derived from the Sinhalese for small insects ( Krombein, 1979). Treat as noun in apposition.

Remarks. The type series was collected with a combined Malaise and yellow flight intercept trap ( FIT). The photographed paratype ( Figs 1–4 View FIGURES 1–7 ) was the only specimen from the FIT and has the antennae badly damaged (pedicel and flagellum entirely lost on right antenna, F2–11 lost on left antenna). The type locality is found in the Indochina Dry Forests habitat. The trap was set out on March 16, 2019 during the dry season, where it had not rained for approximately four months. Only 2 mm of rain was recorded on one of the active trap days (March 20, 2019: www. wunderground.com, accessed June 11, 2019). Based on these extremely limited data, Kudakrumia malaenglek appears to be a dry-adapted species.
