Karyotypes of four species of the genus Telenomus Haliday, 1833 (Hymenoptera: Scelionidae)

Abstract

4000 species in the world fauna [Timokhov, 2019]. Among the Scelionidae, karyotypes of six members of the subfamily Telenominae that belong to the genera Trissolcus Ashmead, 1893 and Telenomus Haliday, 1833 were previously studied (see Gokhman, Timokhov, [2019] for review). Although all examined species appeared to have the same haploid chromosome number, n = 10, at least some members of the family can differ in certain details of their karyotype structure [Gokhman, Timokhov, 2019]. Moreover, for both studied Telenomus species, either the chromosome number remains the only known karyotypic feature, as in T. turesis Walker, 1836 [= chloropus (Thomson, 1861)] [Gokhman, 2009], or the existing description of the chromosome set contains apparent errors, e.g. presence of the putative “sex chromosomes”, as in T. fariai Costa Lima, 1927 [Dreyfus, Breuer, 1944]. Using chromosome morphometrics, we have recently studied karyotypes of four members of the genus Telenomus including T. turesis. The results of this work are given below.
