Remarks.

Bohart (in Kimsey and Bohart 1991: 461) designated the lectotype and placed Chrysis semenovi in the Chrysis comparata - scutellaris group. The three specimens labelled by Bohart were found under the label Chrysis semenovi R. and belong to two different species. However, the two specimens considered as paralectotypes have not been labelled by Radoszkowski and do not match the original description. On the anterior surface, the colour of the first tergite is blue contrasting with the red colour of the remaining part of the segment. According to the original description "Abdomen régulièrment scrobiculé feu-doré; premier segment tirant au jaune-doré, les deuxième et troisième plus rouges [...]".

The specimen selected as lectotype belongs to the cerastes group and not to the comparata - scutellaris group. Radoszkowski himself added in his diagnosis: "Voisine de Chrysis incerta Rad.". Chrysis semenovi is very close to Chrysis annulata Abeille de Perrin (in du Buysson), 1887, and the main characteristics which allows separation of the two species is the shape of the transversal frontal carina. In Chrysis annulata there are two branches directed backwards on the vertex, while in Chrysis semenovi the transversal frontal carina is simple, without branches on the vertex.
