Taxonomic changes in Ichneumonoidea (Hymenoptera), and notes on certain type specimens Author Broad, Gavin R. text Zootaxa 2021 2021-03-10 4941 4 511 541 journal article 7660 10.11646/zootaxa.4941.4.3 a4583583-90dc-415f-923c-334c5dc9ce60 1175-5326 4595588 8DDC8255-7E11-4135-AF8E-F60FF1AB6827 2. Cyclophatnus flavus Cameron 1910 ( Fig. 2 ) Current combination. Gyroneuron flavum ( Cameron 1910 ) new combination ( Braconidae : Rogadinae ). Gyroneuron testaceator Watanabe 1934 : new synonymy Material examined. Cyclophatnus flavus ♀ holotype , NHMUK , Darjeeling, India : ‘Danjiling [sic]’; ‘ Cyclophatnus flavus Cam. Darjiling’; ‘P. Cameron Coll. 1914-110’; ‘ ♀ Cyclophatnus flavus Cameron, 1910 C. van Achterberg, 1979 Holotype’; ‘ C. flavus B.M. TYPE HYM 3C.1821’; ‘ NHMUK 010634938’. Gyroneuron testaceator ♀ holotype , SDEI , Taiwan : ‘DEI-GISHym 10624’; ‘ Gyroneuron testaceator Wat. det. Belokobylskij ‘90’; ‘ Gyroneuron ♀ testaceator Watanabe Type’; ‘Coll. DEI Eberswalde’; ‘Holotypus’; ‘Gyroneuronella n. sp. ’; ‘Kankau (Koshun) Formosa H. Sauter V+.1912’. Cameron (1910) described the genus Cyclophatnus and its one included species, Cyclophatnus flavus , in the Macrocentrinae and it has remained classified as such ever since. Somebody had added the name Gyroneuron above Cyclophatnus in the NHMUK collection and I can confirm that the holotype of Cyclophatnus flavus (3c.1821, NHMUK 010634938; Fig. 2 ) is a species of Gyroneuron , of the subfamily Rogadinae . Gyroneuron Kokujev = Cyclophatnus Cameron , syn. nov. ; Gyroneuron flavum (Cameron) is a new combination . I was able to compare the specimen with photographs of the holotype of Gyroneuron testaceator Watanabe 1934 in SDEI , one of only two previously described species of Gyroneuron , and they appear to be conspecific, so G. testaceator is a junior synonym of G. flavum , syn. nov. Gyroneuron flavum has a wide range, over China , India (type locality of Cyclophatnus flavus ), Taiwan and Vietnam ( Chen & He 1997 ; Long & Belokobylskij 2004 ). The holotype status of NHMUK 010634938 was checked by van Achterberg in 1979. The published type depository was Berlin (‘Royal Berlin Zoological Museum’) ( Cameron 1910 ), but the specimen was acquired by NHMUK from Peter Cameron in 1914. It should probably be returned to Berlin.
