External margin of paramere uniformly rounded, broadly rounded apically, ( Figs 39K View Fig , 40K View Fig ); cuspis volsellaris acute apically ( Fig. 40K View Fig ); aedeagus with eight teeth, serrated margin convex apically, concave basally ( Fig. 42K View Fig ).
Distribution ( Fig. 3A–B View Fig )
China (Anhui, Beijing, Fujian, Hong Kong, Jiangsu, Jilin, Shandong, Shanghai, Sichuan, Taiwan, Zhejiang); India (Arunachal Pradesh, Delhi, Himachal Pradesh, Karnataka, Kerala, Manipur, Rajasthan, Tamil Nadu, Uttarakhand, West Bengal, Sikkim, Assam); Sri Lanka; Japan (Okinawa); Bhutan; Myanmar (Pegu Hills, Rangoon, Tenasserim); Malaysia ( Malacca, Pahang); Laos; Vietnam (South and North [ Cochinchina and Tonkin]; Singapore. [ Betrem 1928; Uchida 1934; Krombein 1978; Gupta & Jonathan 2003; Kumar & Pham 2015; Nidup et al. 2017; Liu et al. 2021b].
Notes
This species is extremely variable in coloration according to Betrem (1941) and Krombein (1978): in both sexes, the head, scapulae and metasomal tergites may be marked with red or entirely black. Scolia binotata is therefore most reliably distinguished from its congeners in Hong Kong by its sparsely punctate mesoscutum which is broadly impunctate medially in the female and has most punctures separated by about their own diameter in the male (in other species of Scolia the mesoscutal punctures are more uniform and closely placed).
Scolia binotata has a history of being confused with S. quadripustulata Fabricius 1782 and specimens from Hong Kong were described by Betrem (1941) under the latter name. True S. quadripustulata , which may not occur outside the Indian subcontinent, differs from S. binotata in having the dorsum of the mesosoma more extensively punctate and hairs on the head mostly black rather than white ( Krombein 1978; Gupta & Jonathan 2003). Subspecies and infrasubspecific varieties recognised by Betrem (1941) to represent colour variants are not geographically distinct and hence probably not worthy of recognition. These include Scolia sexpustulata Klug, 1805 , Scolia humeralis de Saussure in de Saussure & Sichel, 1864 and Scolia quadripustulata birmanica var. octopustulata Betrem, 1941 , specifically used to refer to variants recorded from Hong Kong.
