Redescription, Female. Body 8.8 mm long.

Head. Head 1.2 × wider than high, densely punctate with interstices between punctures 0.3–0.5 PD wide and polished; posterolateral margin of posterior ocelli deeply hollow; ASD:MOD:OOL:POL:OCL:MS = 1.0:1.0:1.6:0.8:2.6:1.0. Mandible blackish brown, medially pale brown. Scape, pedicel and proximal half of F1 reddish testaceous; distal half of F1 dark brown, rest of antennae black. Relative lengths of Ped:F1:F2:F3 = 27:13:9:10. Pubescence on head whitish, 1.0–1.5 MOD, long. Holotype lacks head.

Mesosoma. Mesosoma 1.8 × longer than wide. Pronotum roughly punctate by dense and deep contiguous punctures; PD twice wider than those on head, with interspaces between punctures 0.2–0.3 PD wide; transverse basal pit row present. Mesonotum roughly punctate; punctures deep and dense but shallower than those on pronotum; interspaces between punctures 0.3–0.5 PD wide. Mesopleuron roughly punctate by deep contiguous punctures as pronotum; punctures above scrobal sulcus smaller; scrobal sulcus ill-defined, extended horizontally, and formed by enlarged and irregular foveae. Metanotum with deep anteromedian pit. Metapectal-propodeal complex dorsally with rugose, irregular carinae. Posterior propodeal projection rounded. Legs not metallic, reddish testaceous with distal apex of tarsi darkened. Forewing pale brown with basal and subapical bands. Wing venation typical for Cleptes . Microtrichia long and thick. Hind wing with distal 2/5 and posterior margin of anal lobe weakly tinged with brown. Pubescence on mesosoma whitish, 1.0 MOD long.

Metasoma. Metasoma 1.4 × longer than wide. First metasomal tergum (T-I sensu Kimsey & Bohart 1991) polished, only bearing small scattered punctures. Second tergum punctate by small punctures, with interspaces polished, 1–2 PD wide. Third tergum densely punctate by small punctures, with interspaces 0.3–0.5 PD wide. Pubescence on metasoma dense, whitish, 1.5 MOD long.

Colouration. Head black with scattered faint purplish lustre; clypeus, lower face around antennal foramen (= antennal socket) and median line metallic green, outer margin and narrow surface between posterior ocelli metallic purple; posterior margin of head narrowly metallic orange. Mesosoma metallic red, with faint golden lustre; metanotum laterally golden; metapectal-propodeal complex metallic green, basally metallic light blue. Most part of metasoma dark metallic purple, but basal 4/5 of first tergum metallic green; golden wide bands present on basal 2/5 of the third tergum and basal half of the fourth tergum; posterior margin of the golden band with metallic blue, rest of the fourth tergum black. Pubescence on head and mesosoma grey, metasoma pale brown to yellowish.
