Hylaeus (Hylaeus) torquatus ( WARNCKE, 1992) – ITIS (2020).

Remarks: In the original description, WARNCKE (1992: 769) classifies the species in the subgenus “ Prosopis ” (= Hylaeus s. str.) between H. tyrolensis and H. funereus . According to our understanding, these species belong to different subgenera. In fact, H. torquatus has special characteristics sui generis, which call both classifications into question. We recognize a closer comparability only with H. sidensis , with which it shares the following characters: the short, apically broadened gonoforcipes of the males, in both sexes the dense strong punctation of the head and mesosoma, so that the sculpture appears matt; the lateral areae of the propodeum are arched without posterior ridge; the white mask is dorsally transversally truncated. The face of the female is completely black.

WARNCKE (1992) described H. torquatus from Mardin and recorded it simultaneously from Hakkâri and Siirt as well as from Syria. Since then the species has not been found again. It is only sparsely collected in Turkey (3 provinces).

Distribution: Syria; Turkey: Hakkâri, Siirt, Mardin.
