CHINA: Hong Kong : HOLOTYPE, ♀, Mang Kung Wo, Malaise trap, 11.viii.2015, UTM: 50Q KK 174 760, 60m, M060, C.Hy. 2, leg. C. Barthélémy [AMNH].
Description.
Female ( Figs 33-34 View Figures 30–42 ): body length 13.0 mm; fore wing length 13.5 mm. Black, with the following parts yellow: two separated spots of clypeus basally ( Fig. 35 View Figures 30–42 ), a band of ocular sinus lower, inter-antennal spot, and border between posterior and dorsa-lateral surfaces of propodeum ( Fig. 37 View Figures 30–42 ); mandible mostly, A3-A12, tegula exclude inner side, apex of parategula, and terminal tarsi dark ferruginous. Wings darkly infuscated.
Head. Head in frontal view wider than long. In frontal view, clypeus ( Fig. 35 View Figures 30–42 ) coarsely punctate, interspaces carinate and irregularly reticulate, swollen in the middle, clypeal maximum width 1.19 × its length, apical width 1.30 × distance between antennal sockets ( Fig. 35 View Figures 30–42 ), width of clypeus 2.82 × apical width, apex deeply emarginated medially and forming acute tooth on each lateral side; frons coarsely punctuate, interspaces carinate and reticulate; vertex punctate, punctures a little sparser than frons and clypeus, with two small separated cephalic foveae somewhat bigger than surrounding punctures, depression for cephalic foveae absent, area behind posterior ocelli depression ( Fig. 38 View Figures 30–42 ); occipital carina complete; interocular distance on vertex 1.06 × that at clypeus in frontal view.
Mesosoma. Mesosoma much longer than wide in dorsal view. Pronotal carina complete; pronotum, mesoscutum, scutellum and metanotum coarsely punctate, these punctures very similar to those on frons; mesoscutum slightly convex, about as long as wide between tegulae; scutellum almost flat; metanotum convex and sloping down to apical margin; mesopleuron coarsely punctate, punctures denser than mesoscutum except large area of epicnemium coriaceous; epicnemial carina present and strong; metapleuron coriaceous and with few minute punctures; propodeum ( Fig. 37 View Figures 30–42 ) without lateral carina, dorsal face coarsely punctate, interspaces between punctures carinate and reticulate, lateral face coarsely and irregularly striate and with a few sparse and shallow punctures, posterior face deeply excavated, basal triangular area with a deep fovea, about 1/3 of length of medio-longitudinal carina, with strong median carina connecting a few oblique striae; border between posterior and dorsa-lateral surfaces round ( Fig. 37 View Figures 30–42 ). Parastigma of fore wing much more than half as long as stigma ( Fig. 39 View Figures 30–42 ); tegula not reaching parategula.
Metasoma. T1 in dorsal view slightly more than twice as wide as (2.12 ×) long ( Fig. 37 View Figures 30–42 ), and slightly narrower than T2 ( Fig. 36 View Figures 30–42 ), basally with transverse carina interrupted mesally; anterior vertical surface of T1 convex, coriaceous, with a few sparse shallow punctures, and obviously separating from dorsal horizontal part; dorso-lateral area behind transverse carina with a few coarse punctures similar to those of mesoscutum, interspaces between punctures slightly carinate; dorsal surface except apex densely punctate, interspaces between punctures not reticulate, and punctures much smaller and sparser than those of head and mesosoma; T2 slightly wider than (1.08 ×) long, densely punctuate, punctures at the base relatively bigger and sparser than those in other part of T2; S2 coarsely punctate and slightly lowered basally; visible parts of T3-T5 minutely punctate, punctures much smaller than those of T2 ( Fig. 36 View Figures 30–42 ).
Male. Unknown.
Distribution.
*China (*Hong Kong).
Remarks.
This species is related to A. diffinis (Giordani Soika, 1986) by T1 with distinct transverse carina ( Fig. 37 View Figures 30–42 ), a yellow band at lower part of ocular sinus, and a yellow inter-antennal spot. It can be distinguished from the related species and other members of the genus by following combination of characters: punctures of T1 basally sparser than A. diffinis , clypeus basally with two separated yellow spots ( Fig. 35 View Figures 30–42 ), and pronotum, mesepisternum, metanotum and metasoma wholly black ( Figs 33-34 View Figures 30–42 ).
Etymology.
The specific name Allorhynchium radiatum is Latin for radiation, referring to the notable marking on the face of the holotype resembling that of the infamous Nuclear Radiation pictogram.
