Trichrysis secernenda  ( Mocsáry, 1912) is similar to Trichrysis cyanea  (Linnaeus, 1758) for habitus, geminate punctures on metasoma and tegula brown; but it can be separated from the latter by: black spots on S2 distinctly large and separated by narrow metallic line (Fig. 102); female F1 fully metallic and F2 partially metallic.


Female. Body length 5.6 mm.

Head. Scapal basin deep, wrinkled and punctate (Fig. 56). TFC single, straight or slightly inverted V-shape. Relative length of P:F1:F2:F3=1.0:2.6:1.4:0.9; F1 l/w=3.5; OOL=1.8 MOD; BOL=1.4 MOD [data taken from pictures]; MS=1.1 MOD; clypeal apex concave.

Mesosoma. Pronotal groove deep; sublateral carina week and incomplete. Metanotum with large antero-median depression (Fig. 55). Episternal sulcus and scrobal sulcus with irregular large foveate punctures (Fig. 57).

Metasoma. Punctuation geminate, on T1 with large punctures; on T2 with smaller punctures and interspaces large and smooth (about 1 PD). T2 without median carina. T3 without prepit bulge; pit row with small and isolated pits. Apex of T3 with three short teeth, and straight interval between median tooth and lateral tooth. S2 black spots large and elongated, separated by narrow metallic line medially (Fig. 60).

Colouration. Body green to bluish-green. Scape, pedicel, F1 and F2 basally metallic green, rest of flagellum black. Tegula brown, with few metallic hints. Legs metallic bluish-green, with tarsi brown.

Male. Differs from female as follows: F1 fully metallic, F2 black; antennal segments shorter, P:F1:F2:F3=1.0:1.5:0.7:0.6; F1 l/w=2.3; BOL=1.7 MOD; OOL=2.0 MOD; MS=1.0 MOD.
