Holophris marginella (Mocsáry) , ♀, Hainan, Bawangling. A. Habitus, lateral view; B. Head, frontal view. C. Head, pronotum and mesoscutum, dorsal view; D. Mesosoma, dorsal view; E. Metasoma, dorsal view; F. T3, posterior view. Diagnosis. Holophris marginella ( Mocsáry, 1890 ) resembles H. thailandica sp. nov. , but can be distinguished from the latter by single row of deep punctures on anterior margin of pronotum (two rows in H. thailandica ) and body colouration. Red specimens of H. marginella are also similar to H. taiwana (Tsuneki) , but can be separated by striated mesoscutellum (smooth and impunctate medially in H. taiwana ). Redescription. Female . Body length 2.9–4.1 mm ( Fig. 4A ). Fore wing length 2.3–2.6 mm . OOL = 1.3 MOD; POL = 2.3 MOD; MS = 1 MOD; relative length of P:F1:F2:F3 = 1:0.8:0.8:0.7. Head. In frontal view, upper profile extremely convex ( Fig. 4B ). Head from scapal basin to occipital area with small, shallow and spaced punctures, with intervals transversally and deeply wrinkled forming continuous striae between punctures. Scapal basin deep and polished, transversally wrinkled toward clypeus. In lateral view, longest distance between genal carina and lower margin of eye 0.8 MOD; genal carina bisecting MS, its end is close to lower margin of eye (0.2–0.3 MOD). Ocellar triangle isosceles. Postocellar line distinctly close to ocelli, medially absent. Gena smooth, almost without wrinkles. Occipital area and ocellar area impunctate, with tiny punctures in ocellar area and sparse tiny punctures on occipital area. Mesosoma. Pronotum impunctate, with sparse tiny punctures; with single row of deep punctures on anterior margin and large, dense (0–0.5 PD) punctures antero-laterally, in corner with corrugated intervals. Mesoscutum impunctate, with sparse tiny punctures ( Fig. 4C ); notaular pits narrow and short (0.5 MOD), notauli indistinct ( Figs 4C, 4D ); lateral field of mesoscutum with row of large and elongated punctures along tegula margin. Mesoscutellum with four foveae on anterior margin, with two median foveae large (1.5 MOD) and two lateral ones smaller (1 MOD); median foveae separated by 0.3 MOD. Mesoscutellum longitudinally wrinkled, with round punctures towards alar fovea ( Fig. 4D ). Metanotum distinctly elongated, with deep, round and large punctures and subequal intervals, with smooth intervals bearing some tiny punctures. Mesopleuron with small and round punctures, with large interspaces (0.2–1.5 PD) with elongated sub-transverse striae from alar fovea to posterior margin ( Fig. 4A ). 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 (1.5–2 MOD). Apex of T3 without median notch ( Fig. 4F ). Colouration. Face metallic blue to green; ocellar area, gena and occipital area black. Mesosoma dorsally black; pronotum antero-laterally, mesopleuron (including or excluding contrasting omaulus), mesoscutellum laterally and intervals between punctures on metanotum metallic uniformly golden-red, red, bronze or green ( Fig. 4D ); bottom of punctures can be non-metallic black contrasting with metallic intervals. Antenna black, with scape metallic blue or green. Tegula brown, without metallic reflection. Legs metallic bluish green, with tarsi testaceous and without metallic reflection. Metasoma entirely black, excluding brown semitransparent rims on posterior margins of T2 and T3. Some specimens with metallic green mesosoma also have green to green-blue metallic T1 and T2. Variation . Holophris marginella shows some colour variation. All specimens with pronotum and mesoscutum black; but some specimens, including some specimens from the Philippines (HNHM) and some specimens from BME and ETHZ, with mesoscutellum and metanotum laterally, propodeum and mesopleuron metallic green; T1 and T2 almost entirely metallic green and T3 black. Other specimens show the same colour pattern, but with red, golden, or bronze colour instead of green; moreover, in red or golden specimens, omaulus area can be blue, in contrast with red, golden, or bronze mesopleuron ( Fig. 4A ) or concolour, and metasoma varies from fully black with weak metallic reflection laterally, to entirely metallic green on T1 and T2. These variations are observed even within same populations in Malaysia and Philippines and are not in relation to sexual dimorphism. Male . Similar to female, except T3 apically round. Distribution. * China ( Yunnan , Hainan ), Malaysia , Philippines , Vietnam ( Mocsáry 1913 ; Baltazar 1966 ; Kimsey & Bohart 1991 ), * Thailand . Remarks. The holotype of Ellampus ( Holophris ) marginellus Mocsáry was not found in the ETHZ collection (teste Rod Eastwood).
