Description

Female

STANDARD RATIOS (n = 2). L: 18.2–18.3 mm (mean = 18.25 mm); CR: 1.13–1.14 (mean = 1.14); OOR: 0.66–0.74 (mean = 0.70); CLR: 0.39–0.41 (mean = 0.40); MER: 1.25–1.28 (mean = 1.26); OMR: 1.02– 1.03 (mean = 1.03); FRR: 1.61–1.69 (mean = 1.62); MSR: 0.78–0.80 (mean = 0.79); TER: 1.51–1.64 (mean = 1.58).

HEAD. Head mostly punctured except on disc of clypeus (impunctate) ( Figs 15F View Fig , 19F View Fig ); frontal spatium not well defined dorsally; frontal furrow not well defined; frontal fissura present on anterior portion of frontal spatium only ( Fig. 15F View Fig ).

MESOSOMA. Scapulae, mesoscutum, scutellum, metanotum and propodeum dorsomedian area densely and strongly punctate ( Figs 22A View Fig , 26F View Fig ), punctures separated by less than their own diameter; dorsolateral area of propodeum somewhat less densely punctate anteriorly ( Fig. 27F View Fig ), puncture separate by at least their own diameter. Mesopleuron densely punctate medially, broadly impunctate posteriorly and anteriorly; upper panel of metapleuron densely punctate dorsally, impunctate ventrally; upper and lower panels of metapleuron with a few faint punctures; lateral panel of pronotum minutely punctate. Scutellum and metanotum without median longitudinal carina ( Fig. 27F View Fig ). Dorso-median area of propodeum without distinct tubercule medially ( Fig. 27F View Fig ).

METASOMA. Metasoma with weak division between anterior and ventral faces of S 2 in lateral view ( Fig. 31F View Fig ); S1 mostly impunctate (shiny) with only a few large punctures laterally, tergites mostly uniformly densely punctate, tergites with a less densely punctured area on the medial apical part ( Figs 31F View Fig , 35F View Fig ). T2 with basal elevation weekly developed (gradulus) ( Fig. 35F View Fig ).

WINGS. Fore wing with two submarginal cells and one recurrent vein. Anterior half of fore wing with numerous short setae.

COLOUR AND VESTITURE. Head red/orange on frontal spatium, vertex except area between eyes, and scapulae ( Figs 15F View Fig , 19F View Fig ), remainder of body black. Vestiture black on entire body ( Fig. 7F View Fig ), except on frontal spatium, clypeus and scapulae where it is pale orange ( Fig. 15F View Fig ). Wings dark brown, infumated with faint iridescence.

Male

Identical to female, except for the presence of a conspicuous ridge (carina) on the frons below median ocellus, clypeus with punctures on disc and the short frontal fissura ( Figs 18A View Fig , 22A View Fig ). Ocellar sinuses entirely and most of interantennal space orange.

STANDARD RATIOS (n = 5). L: 13.4–15.7 mm (mean = 14.3 mm); CR: 1.07–1.13 (mean = 1.09); OOR: 1.18–1.50 (mean = 1.37); CLR: 0.61–0.65 (mean = 0.63); MER: 1.25–1.35 (mean = 1.31); OMR: 0.87– 0.95 (mean = 0.91); FRR: 1.71–1.92 (mean = 1.83); MSR: 0.76–0.83 (mean = 0.79); TER: 1.67–1.79 (mean = 1.72).

GENITALIA. Ventral and dorsal side of paramere with sparse long setae ( Figs 39H View Fig , 40H View Fig ); volsella with long setae on its entire surface ( Fig. 42H View Fig ), cuspis volsellaris densely setose. Volsella bearing a few sensory cones on its external margin, acutely rounded apically ( Fig. 40H View Fig ); External margin of paramere strongly rounded medially, paramere broadened medially; aedeagus with 12 teeth, the last apical tooth very reduced, serrated margin substraight apically, sharply convex medially and substraight/concave basally ( Fig. 42H View Fig ).

Distribution

China (Fujian, * Hong Kong, Xizang, Yunnan); Japan; South Vietnam. [ Betrem 1941; Liu et al. 2021b].

Notes

Following its original description ( Betrem 1928) as Scolia junnanensis , the name of this species has subsequently been spelt by Betrem (1941) and Liu et al. (2021b) as ‘ yunnanensis ’. However, ICZN Art. 32 requires the original spelling be maintained. The spelling ‘ yunnanensis ’ cannot be regarded as a justified emendation under Article 32.5, as Betrem (1928) also spells the name of the species’ collection location as ‘Jünnan’ (evidently intending the German reading of this spelling). Contra Liu et al. (2021b), Betrem’s (1928) usage does not represent a nomen nudum as a full description is provided.

Previous descriptions of this species ( Betrem 1941; Liu et al. 2021a) refer to yellow/orange markings on T3 and sometimes T4 that are absent in specimens from Hong Kong. Nevertheless, all other characters are identical to these earlier accounts. Betrem (1941) recognized two subspecies, C. j. junnanensis and C. j. tibetensis Betrem, 1941, distinguished on the basis of coloration. Specimens from Hong Kong are not attributable to either subspecies. However, in light of the extreme colour variability in Scoliidae and the absence of a systematic review of variation within C. junnanensis , we refrain from designating a new subspecies for the Hong Kong population. Carinoscolia junnanensis is the only representative of this small genus in Hong Kong; with eight species worldwide.
