Cotesia sp. 1

Distribution.

NEA. High Arctic endemic.

Notes.

A series from Southampton Island (five specimens mounted but more than 40 additional specimens in alcohol, kept with the host remains and wasp cocoons mass). The species is morphologically similar to C. hallii and C. eliniae, but is distinctive because of the very strong and deep sculpture on mediotergites 1, 2 and at least anterior 0.2-0.3 of mediotergite 3 (in contrast, C. eliniae has most of mediotergites 1-3 sculptured, but the sculpture is much finer and mat). One of the specimens (voucher code CAM0668) has a partial barcode (421 base pairs) which is unique among all Cotesia specimens in BOLD, and rather different from those of C. hallii and C. eliniae . Host: Gynaephora sp. ( Lymantridae).
