Geographical variation and sex-ratio in Leucospis gigas (Hymenoptera, Chalcidoidea)
Acta Entomologica Musei Nationalis Pragae 35: 527-530, 1963
Abstract: In Israel occur two different forms of Leucospis gigas F.: f. typica and f.
rufonotata Westw. which should be considered subspecies as they show differences
in colouration, exclude each other geographically (Fig. 1) and show different
tendencies towards melanistic variation. Furthermore in the f. rufonotata Westw.
males occur regularly (probably 50 % J while from the f. typica no males are
known. It is probable that some of the North African populations of L. gigas
also belong to the f. rufonotata Westw.
