Diagnosis. Holophris thailandica sp. nov. resembles H. marginella ( Mocsáry, 1890) in general habitus and striated mesoscutellum. It can be separated from the latter by two rows of punctures on anterior margin of pronotum (only one row in H. marginella ), and its metallic blue to greenish-blue body in contrast with golden to red mesoscutellum and metanotum ( Figs 6A–6F ) (body mainly black, without contrasting colouration in H. marginella ).

Description. Female. Body length 2,5–3.0 mm ( Fig. 6A ). Fore wing length 1.6–1.8 mm. OOL = 1.4 MOD; POL = 2.3 MOD; MS = 1.2–1.4 MOD; relative length of P:F1:F2:F3 = 1:0.9:0.7:0.7.

Head. Head from scapal basin to occipital area with sparse punctures ( Fig. 6B ), with transverse wrinkles forming continuous striae between punctures. Scapal basin deep, with weak transverse wrinkles. In lateral view, longest distance between genal carina and lower margin of eye 0.5–0.8 MOD; genal carina bisecting MS, its end near lower margin of compound eye. Ocellar triangle isosceles, mid ocellus close to postocellar line. Postocellar line medially absent. Gena with longitudinal wrinkles. Occipital area and ocellar area smooth and impunctate, with sparse tiny punctures.

Mesosoma. Pronotum impunctate, with sparse tiny punctures; with two rows of small and deep punctures on anterior margin and large, dense punctures antero-laterally, on propodeal corner with corrugated intervals. Mesoscutum impunctate, with sparse tiny punctures ( Fig. 6C ); notaular pits narrow and short (0.5 MOD), notauli indistinct ( Fig. 6C ). Mesoscutellum with four anterior foveae, two median foveae large (1.5 MOD), two lateral foveae smaller (1 MOD), median foveae separated by 0.3 MOD; mesoscutellum longitudinally wrinkled, with sparse and round punctures towards alar fovea ( Fig. 6C ). Metanotum evenly round and distinctly elongated ( Fig. 6D ), with deep and round punctures subequally interspaced, with distinct smooth intervals bearing some tiny punctures. Mesopleuron with small, round and spaced punctures, with elongated subtransverse striae extending from alar fovea to posterior margin. Tarsal claw with three teeth.

Metasoma. T1 impunctate. T2 and T3 almost impunctate, with sparse tiny punctures close to lateral margins. T1 without semitransparent rim; T2 and T3 with wide brown semitransparent rim (2 MOD). Apex of T3 without median notch ( Fig. 6F ).

Colouration. Head and pronotum metallic greenish-blue to dark blue. Mesoscutum black, without metallic reflection. Mesoscutellum and metanotum metallic golden to red. Metasoma metallic dark blue to violet, sometimes dorsally black, without metallic reflection. Scape and pedicel metallic blue or green, flagellum black. Tegula brown, without metallic reflection. Legs metallic bluish green, except tarsi testaceous and without metallic reflection.

Male. Similar to females, except tarsi lighter; mesoscutellum and metanotum black, without metallic reflections; T3 apically round.

Distribution. Thailand.

Etymology. The new species is named after the country of collection.
