Halbert T91-061" (TAMU-ENTO accession numbers: X0855626 to -39, X0855641). 7 card mounts (5 females, 2 males) of voucher specimens from non-destructive DNA extraction, with label data reading "KAZAKHSTAN | Dmitrevka | 13.v.1991 | Popraski & Halbert | EPL-92-60 || DNA extracted | BIIRL 2014" (TAMU-ENTO accession numbers: females: X0856043, X0856045, X0856074, X0856076, X0856078; males: X0856041, X0856077), and two additional card mounts (1 female, 1 male) with the same label data (TAMU-ENTO accession numbers X0856689 and X0853796). 12 slide mounts (6 female, 6 male) with the same label data as holotype.

Other material examined.

None.

Hosts.

The original material was collected from Diuraphis noxia in the field in Dmitrievka, Kazakhstan. In lab culture, Diuraphis noxia on wheat was used as the host.

Distribution.

The species is known only from type material from Dmitrievka, Kazakhstan.

Discussion. The collections from Kazakhstan, Dmitrievka correspond exactly to those discussed in Kazmer et al. (1996). The most notable distinction between A. kazakhstanensis and all other A. asychis group species is the yellow mesotibia, combined with the profemur, mesofemur, and metatibia light brown at base and yellow at apex. Aphelinus asychis specimens have mesotibia, metatibia, profemur, and mesofemur dark brown at base and yellow at apex. Aphelinus semiflavus has mesotibia, profemur, and mesofemur yellow, and metatibia brown at base and yellow at apex. Aphelinus sinensis specimens have mesotibia, metatibia, profemur, and mesofemur all yellow.
