( Figs 80 A–80F)

Chrysis imperiosus Smith, 1874: 460 . Lectotype ♀ designated by Bohart in Kimsey & Bohart 1991: 533; Australia: Queensland, Moreton Bay ( NHMUK). Chrysis imperiosa: du Buysson 1898a: 142 (Hindoustan [= India]: Karnataka: Kanara ; Maharashtra: Poona [= Pune ]); Bingham 1903: 438 (key), 479–480 (descr., Sikhim [= Sikkim]; West Bengal: Barrakpore), 479 (fig. 159), pl. I (fig. 13). Chrysis (Pentachrysis) imperiosa: Bischoff 1910: 486 (cat., Assam, West Bengal: Darjeeling). Chrysis (Trichrysis) imperiosa: Roy & Kundu 1985: 227 (Arunachal Pradesh: Namdhapa [=Namdapha]). Praestochrysis imperiosa: Strumia 1996: 62 ( India, descr.), 61 (fig. 3).

Material examined: 2 ♀, Meghalaya, Khasia Hills, wihtout further data ( ETHZ) ; 1 ♀, Kerala, Travancore, v.1935 ( MNLU) ; 1 ♀, Kerala, Quilon, Thenmala, leg. Nathan, without further data ( PRC) .

Distribution. India (Assam; Karnataka; Kerala; Maharashtra; Meghalaya; Sikkim; West Bengal; Arunachal Pradesh); China ( Taiwan, Hunan, Guangdong, Hainan) ( Rosa et al. 2016a); Australia, Myanmar, Sri Lanka ( Bingham 1903); Vietnam ( Kimsey & Bohart 1991); Indonesia, Nepal, Papua New Guinea, Thailand ( Rosa et al. 2016a).

Remarks. Several species are currently found under the name Trichrysis imperiosa (B. Wiśniowski, in litteris). The Indian species should belong to Trichrysis cupreidorsus ( Tsuneki, 1963) (holotype from Thailand), which was syonymized by Kimsey & Bohart (1991: 533) with Praestochrysis lusca ( Fabricius, 1804) , without type examination. Also, the Chinese specimens identified as T. imperiosa from Guandong ( Rosa et al. 2016a) should belong to a different species.
