Diagnosis.

Chrysis yoshikawai is similar to C. ignifascia , but can be separated by: female body entirely green to blue, without reddish or golden colouration (with reddish golden stripe posteriorly on T2 in C. ignifascia ), male S2 with sub-reniform and transverse black spots (Fig. 7B) (sub-triangular and longitudinal in C. ignifascia , Fig. 7A), and T3 with darkened clover-shaped spot (Figs 6E, 6F).

Description.

Female (Fig. 6A). Body length 7.5 mm.

Head. Scapal basin fully striate and with micropunctate ground sculpture. TFC double, sharply raised (Fig. 6B). Relative length of P:F1:F2:F3 = 1.0:1.3:1.0:0.7. OOL = 2.0 MOD; BOL = 1.5 MOD; POL = 2.1 MOD; MS = 0.5 MOD; subantennal space 0.5 MOD. Genal carina well developed throughout its length (Fig. 6D).

Mesosoma. Pronotal groove shallow and reaching 2/3 of pronotum length. Mesoscutum and mesoscutellum evenly punctate; metanotum with coarse punctures (Fig. 6C). Mesopleuron with deep episternal and scrobal sulci, both sulci with large foveae (Fig. 6D).

Metasoma. Metasoma with large, even punctures; the punctures as large as on mesoscutum (Fig. 6E). T2 and T3 with median ridge; T3 weakly saddled with deep pit row; apex of T3 slightly concave in the middle (Fig. 6F). Black spots on S2 sub-reniform, transverse, separated by less than 1.0 MOD (Fig. 7B).

Colouration. Body metallic blue to green, with dark blue on vertex, mesoscutum medially, tegula, T1 anteriorly, T2 anteriorly and T3 anteriorly (a typical clover-shaped pattern) and posteriorly (from pit row to posterior margin).

Male. Similar to female.

Distribution.

China (new record). Thailand ( Tsuneki 1961; Kimsey and Bohart 1991).

Remarks.

Tsuneki (1961) did not mention the repository of the holotype. Kimsey and Bohart (1991) reported it at OMNH, wherein it was not found (Dr. Rikio Matsumoto, pers. comm.).
