Diagnosis.

Trichrysis trigona ( Mocsáry, 1889) is similar to Trichrysis coeruleamaculata sp. n., but it can be easily separated from the latter by: body punctuation without interspaces between large punctures or with small wrinkled interspaces; OOL=2.0 MOD; scapal basin striate medially; T1, T2 and T3 each with two small blue spots; tegula entirely metallic blue.

Description.

Female. Body length 7.0 mm.

Head. Scapal basin deep, punctate laterally and striate medially (Fig. 83). TFC with endbending downwards. Area beneath TFC raised with punctures elongate longitudinally, TFC appearing double. Clypeus almost truncated. P:F1:F2:F3 = 1.0:1.2:0.8:0.8; F1 l/w = 2.5; OOL = 1.5 MOD; BOL = 1.6 MOD; POL = 2.2 MOD; MS = 1.1 MOD.

Mesosoma. Pronotal groove weak; pronotum deeply concave laterally; sublateral carina incomplete, well developed only anteriorly. Mesoscutellum and metanotum without antero-median depression or pit. Punctuation on mesosoma continuous without interspaces between large punctures or with small and wrinkled interspaces (Fig. 84). Episternal sulcus and scrobal sulcus with large foveate punctures (Fig. 82).

Metasoma. Metasoma with dense and large punctures (Fig. 85), dorsally on T2 with large punctures geminate and with wrinkled interspaces between punctures, with punctures subtransversely aligned; punctures on T3 smaller, wrinkled over pre pit area (Fig. 87). T2 without median carina. T3 prepit bulge medially convex; pit row distinct, with small, almost indistinct and separated pits (Fig. 87). Apex of T3 with three sharp teeth, with interval between median tooth and lateral tooth concave. S2 black spots triangular, elongated longitudinally and partially fused medially (Fig. 106).

Colouration. Body bluish-green, with small blue spots on vertex, mesoscutum, mesoscutellum, metanotum, with two small symmetric blue spots on T1, T2 and T3, respectively. Antenna blackish, with scape, pedicel and F1 metallic bluish-green. Tegula metallic blue. Legs metallic bluish-green, with tarsi blackish-brown without metallic reflections.

Male. Unknown.

Distribution.

China (Hong Kong?), Laos ( Kimsey and Bohart 1991); Indonesia; Pakistan (new record).
