Revision of the western Palaearctic species of Aleiodes Wesmael (Hymenoptera, Braconidae, Rogadinae). Part 2: Revision of the A. apicalis group.

The West Palaearctic species of the Aleiodes apicalis group (Braconidae: Rogadinae) as defined by van Achterberg & Shaw (2016) are revised. Six new species of the genus Aleiodes Wesmael, 1838, are described and illustrated: A. carbonaroides van Achterberg & Shaw, sp. nov., A. coriaceus van Achterberg & Shaw, sp. nov., A. improvisus van Achterberg & Shaw, sp. nov., A. nigrifemur van Achterberg & Shaw, sp. nov., A. turcicus van Achterberg & Shaw, sp. nov., and A. zwakhalsi van Achterberg & Shaw, sp. nov. An illustrated key to 42 species is included. Hyperstemma Shestakov, 1940, is retained as subgenus to accommodate A. chloroticus (Shestakov, 1940) and similar species. Fourteen new synonyms are proposed: Rogas bicolor Lucas, 1849 (not Spinola, 1808), Rogas rufo-ater Wollaston, 1858, Rhogas bicolorinus Fahringer, 1932, Rhogas reticulator var. atripes Costa, 1884, and Rhogas similis Szépligeti, 1903, of Aleiodes apicalis (Brullé, 1832); Rogas (Rogas) vicinus Papp, 1977, of Aleiodes aterrimus (Ratzeburg, 1852); Rogas affinis Herrich-Schäffer, 1838, of Aleiodes cruentus (Nees, 1834); Bracon dimidiatus Spinola, 1808, and Rhogas (Rhogas) dimidiatus var. turkestanicus Telenga, 1941, of Aleiodes gasterator (Jurine, 1807); Rogas alpinus Thomson, 1892, of Aleiodes grassator (Thunberg, 1822); Rhogas jaroslawensis Kokujev, 1898, of Aleiodes periscelis (Reinhard, 1863); Rhogas carbonarius var. giraudi Telenga, 1941, of Aleiodes ruficornis (Herrich-Schäffer, 1838); Ichneumon ductor Thunberg, 1822, of Aleiodes unipunctator (Thunberg, 1822); Rogas heterostigma Stelfox, 1953, of Aleiodes pallidistigmus (Telenga, 1941). Neotypes are designated for Rogas affinis Herrich-Schäffer, 1838; Rogas nobilis Haliday (in Curtis), 1834; Rogas pallidicornis Herrich-Schäffer, 1838; Rogas ruficornis Herrich-Schäffer, 1838. Lectotypes are designated for Rhogas (Rhogas) dimidiatus var. turkestanicus Telenga, 1941, and Rhogas hemipterus Marshall, 1897. Cornelis van Achterberg, Mark R. Shaw, Donald L. J. Quicke.
