A review of the genus Zygota (Hymenoptera, Diapriidae) in Germany with taxonomic notes on this genus and its distinction from Pantoclis

Abstract

This study provides a comprehensive overview of the genus Zygota Förster combining DNA barcoding and current morphology. Nineteen species of Zygota were found throughout Germany, including the newly described species Zygota walli sp. nov. First species records for Germany are: Zygota balteata Macek, 1997; Z. comitans Macek, 1997; Z. spinosipes (Kieffer, 1908); Z. sordida Macek, 1997; Z. angularis Macek, 1997 and Z. vigil Nixon, 1957. We also clarify diagnoses for the two related genera, Pantoclis Förster and Zygota to designate the boundaries of the Zygota genus and propose new synonymies: Zygota caligula Buhl, 1997 is a junior synonym of Z. congener (Zetterstedt, 1840); Z. reticulata Kozlov, 1978 is a junior synonym of Z. ruficornis (Curtis, 1831). Thirteen species of Zygota sensu Nixon (1957) are transferred to the genus Pantoclis with the following new combinations proposed: Zygota brevinervis (Kieffer, 1908) (= Pantoclis brevinervis (Kieffer, 1909), comb. nov.); Z. brevipennis (Kieffer, 1908) (= P. brevipennis (Kieffer, 1908), comb. nov.); Z. caecutiens (Kieffer, 1908) (= P. caecutiens (Kieffer, 1908), comb. nov.); Z. cursor (Kieffer, 1908) (= P. cursor (Kieffer, 1908), comb. nov.); Z. fossulata (Thomson, 1858) (=P. fossulata (Thomson, 1858), comb. nov.); Z. fuscata (Thomson, 1858) (= P. fuscata (Thomson, 1858), comb. nov.); Z. hemiptera (Thomson, 1858) (= P. hemiptera (Thomson, 1858), comb. nov.); Z. microtoma (Kieffer, 1909) (= P. microtoma (Kieffer, 1909), comb. nov.); Z. soluta (Kieffer, 1907) (= P. soluta (Kieffer, 1907), comb. nov.); Z. striata (Kieffer, 1909) (= P. striata (Kieffer, 1909), comb. nov.); Z. subaptera (Thomson, 1858) (= P. subaptera (Thomson, 1858), comb. nov.); Z. sulciventris (Kieffer, 1909) (= P. sulciventris (Kieffer, 1909), comb. nov.), and Z. unicolor (Kieffer, 1908) (= P. unicolor (Kieffer, 1908), comb. nov.).
