Name
Trichrysis coeruleamaculata Rosa, Wei & Xu sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Material examined
Holotype, ♀: CHINA: Fujian, Fuzhou, Jingshan (26°17’12”N 118°58’52”E), 21.VIII.2004, leg. C-m. Liu (SCAU).
Diagnosis
Trichrysis coeruleamaculata sp. n. is similar to Trichrysis trigona (Mocsáry, 1889) and Trichrysis hexapholis Bohart, 1987, from Sri Lanka. It can be separated from Trichrysis trigona by the following characteristics: body punctuation with large interspaces, 0.2–1.0 PD; scapal basin punctate; pit row with large pits; pit row sunken with deep pits, and post pit row area impunctate; T1 and T3 each with two dark blue spots, T2 dark blue dorsally; tegula brown or with feeble metallic reflections; S2 with large black spots as in Fig. 96. It can be separated from Trichrysis hexapholis by blue colouration without bright purple and gold markings; TFC straight and not as inverted V.
Description
Female. Holotype. Body length 8.0 mm.
Head. Scapal basin deep and punctate. TFC single and straight (Fig. 2). Frons slightly raised between TFC and scapal basin. Relative length of P:F1:F2:F3=1.0:1.3:0.7:0.6; F1 l/w=2.9; OOL=1.2 MOD; BOL=1.7 MOD; POL=2.0 MOD; MS=1.2 MOD; clypeus incised medially.
Mesosoma. Pronotal groove deep, almost extending to posterior margin of pronotum (Fig. 3); sublateral carina incomplete, well developed only anteriorly. Punctuation on pronotum, mesoscutum and mesoscutellum with large interspaces between punctures, 0.2–1.0 PD (Fig. 3); interspaces shining and punctate. Episternal sulcus and scrobal sulcus with large areolate punctures.
Metasoma. Metasoma with large geminate punctures and punctate interspaces (Fig. 4). T2 with weak median carina (Fig. 4). T3 prepit bulge slightly convex; pit row distinct, with large pits; post pit row area flat and impunctate (Fig. 5). Apex of T3 with three sharp teeth (Fig. 5); interval between median tooth and lateral tooth concave. S2 black spots subtriangular, elongated longitudinally and fused medially (Figs 6, 96).
Colouration. Body metallic blue (Fig. 1), with dark blue spots on vertex, pronotum, mesoscutum, mesoscutellum, and metanotum medially; with two dark blue, large and symmetrical spots on T1, T2 and T3, respectively (Fig. 4); with green reflections on face, lateral fields of mesoscutum. Scape, pedicel and only base of F1 metallic bluish-green, rest of flagellum black. Tegula brown, with weak metallic reflections. Legs metallic bluish-green, with tarsi brown.
Male. Unknown.
Distribution
China (Fujian).
Etymology
The specific name derives from Latin adjective coerulea (= blue) and Latin past participle maculata (= spotted) and refers to blue spots on T3 before pit row.
