MESOSOMA (Fig. 10H–I). Length 1.5 × its width in lateral view (Fig. 10I); side of pronotum rugulose except for finely punctation; mesoscutum regularly and densely reticulate; notauli absent; scutellar sulcus with five short crenulae (Fig. 10H); scutellum largely finely punctate except basally reticulate; mesopleuron densely and regularly reticulate without smooth and shiny area posteriorly, with weak and incomplete precoxal sulcus basally; propodeum reticulate, without median carina, with irregular transverse carina connected to four weak and blunt lateral tubercles. WINGS (Fig. 10G). Fore wing 3.2× as long as its maximum width; second submarginal cell sessile; vein m-cu distinctly postfurcal; veins r and SR1 straight; vein 1-SR+M slightly concave; length of 1-R1 1.2 × pterostigma; vein r issued far beyond middle of pterostigma, 1.5 × vein r-m; r: 2-SR: SR1 =17: 42: 79; vein 1-CU1 0.3× as long as vein 2-CU1. Hind wing: M+CU:1-M:1r-m =30: 50:17. LEGS (Fig. 10F). Hind femur 4.4 × as long as wide; longest spur of hind tibia 0.4 × its basitarsus; hind leg smooth and shiny except fine and superficial punctation; hind tibia slender; middle tibia without ivory blister. METASOMA (Fig. 10E, J). Oval in dorsal view (Fig. 10J), carapace 1.7 × as long as wide and as long as mesosoma; first to third tergites densely reticulate-rugose; third tergite 1.0× as long as second tergite, medial length of third tergite 0.5× its maximum width; lamella of third tergite not protruding medio-apically and with pair of medium-sized and blunt tubercles latero-apically (Fig. 10E). VARIATION. Length of fore wing of female 4.0– 4.6 mm. Male Unknown. Host Unknown. Distribution China (Fujian, Guangdong, Guangxi). Remarks Phanerotomella aurantisoma sp. nov. is similar to P. digitata sp. nov. because of its having the antenna with a white band on 3 rd –5 th segments, mesosoma orange-brown and eye in dorsal view as long as temple. However, Phanerotomella aurantisoma can be distinguished from P. digitata by having the propodeum with a pair of small and blunt tubercles latero-posteriorly (distinctly larger and finger-shaped tubercles in the latter), a punctate and shiny scutellum (reticulate and matt in the latter), a punctate and shiny temple and face (rugulose and matt in the latter), a comparatively slender mandible and the inner tooth 0.4× as long as apical tooth (more robust and 0.5× in the latter).
