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.
