Remarks

Chrysis spectrum (Fig. 3) was described five years after Bingham’s description of Chrysis lanka . In the paper, Wickwar (1908) listed four specimens, but only two are still preserved in the collection at NHMUK, both in rather poor condition, mainly due to mould. Both are specimens of Trichrysis lanka . Bohart in Kimsey & Bohart (1991) designated the lectotype of T. spectrum and synonymised it with T. lanka . Unfortunately, no specimen examined at NHMUK bears a lectotype label, and no information has been provided by Kimsey & Bohart (1991) to recognise the selected lectotype in the collection, thus making the designation invalid. To prevent further misunderstandings, we (BW) here designate the lectotype based on the female (Fig. 3) bearing the labels: Colombo, Ceylon, O.S.W.; Ceylon O.S.Wickwar 1912-189; Chrysis spectrum; Type O.S. Wickwar; B.M. Type Hym. 13.52 [13G Chrysididae, drawer 71]. The type of Chrysis lanka was not found at NHMUK (Kimsey & Bohart 1991, pers. comm.) and could possibly be deposited in the Mocsáry collection (HNHM), who bought part of the Bingham collection (Rosa et al. 2017).
