Revision of Hycleus solonicus (Pallas, 1782) (Coleoptera: Meloidae, Mylabrini), with larval description and DNA barcoding

Abstract

Hycleus solonicus (Pallas, 1782), referred to H. polymorphus species group, is revised. Adults are redescribed and illustrated, eggs and first-instar larvae are described and illustrated for the first time, COI sequence for DNAbarcoding is reported for the first time, the geographical distribution is revised and all available faunistic records from the literature and collections are summarized. In addition, two incorrect determinations are pointed out and Zonabris solonica var. dianae Sahlberg, 1913 is proposed to be a synonym of Hycleus scabiosae (Olivier, 1811).
