Sri Lanka ( Bingham 1903 ). 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 ).
