lmmature stages of Rhabdotocarabus melancholicus ssp. dehesicola (García-París & París, 1995) (Coleoptera, Carabidae)

Abstract

In this paper, data on the irnmature stages (first, second and third larval instars and pupa) of Rhabdotocarabus melancholicus dehesicola (García-París & París, 1995) are given. Descriptions are based on rnorphological and biometrical studies made of individuals (four of each instar) obtained from cultures reared in laboratory with imagoes caught in the Arenosillo strearn (S lberian peninsula). Cornments about the outstanding differences between the immature stadia of R. melancholicus and those of other sympatric Carabus(s.l.) species are also included. The following morphological structures were sufficient to identify this species: epistome, supraocellar tubercle, mandibles and urogomphi for larvae, or prothoracic pubescence for pupae.
