11. Acrodactyla lachryma Pham, Broad, Matsumoto & Böhme 2012

Current combination. junior synonym of Acrodactyla iliensis Sheng & Bian 1996 new synonymy ( Ichneumonidae : Pimplinae ).

Material examined. Acrodactyla iliensis Sheng & Bian 1996 ♀ holotype, GSFPM, China, Xinjiang, Yili , 662 m, July 8, 1989. Bian Xiyuan; Acrodactyla lachryma Pham, Broad, Matsumoto & Böhme 2012 ♀ holotype, RMNH, Vietnam, Kon Tum, Chu Mom N.P., 700-900 m a.s.l., Malaise trap 26.ix-5.x.2006, Q.P. Mai & M.T. Nguyen leg.

Comments. The Chinese holotype female of Acrodactyla iliensis in GSFPM was examined. This proved to be a senior synonym of Acrodactyla iliensis , described from Vietnam ( Pham et al. 2012). There are some minor differences, in particular the holotype of A. iliensis is more extensively red on the mesosoma and the hind wing nervellus is intercepted a little lower (the abscissa of vein CU is relatively longer than cu-a in the holotype of A. iliensis compared to the holotype of A. lachryma ), but these seem to be within the usual range of variation to be expected in pimplines. Although the reported ovipositor lengths are very different in the two descriptions ( Sheng & Bian 1996; Pham et al. 2012), there was no measurable difference between the specimens. Acrodactyla iliensis belongs to the Acrodactyla quadrisculpta group as the fore femur is prominently toothed. Another very similar species is Acrodactyla orientalis (Cushman 1933) , although A. orientalis lacks the ‘tooth’ projection on the fore femur.
