CALLODICOPUS Ogloblin, 1955

(Figs 163–183)

Callodicopus Ogloblin, 1955: 377 . Type species: Callodicopus crassula Ogloblin, 1955, by original designation.

Decamymar Annecke, 1961b: 68 . Type species: Decamymar magiclavae, Annecke, 1961, by monotypy. Synonymy by Huber & Lin, 1999: 26.

Diagnosis. Funicle 7-segmented, with fu 2 about as long as fu 1 or fu 3 (Fig. 166); mandibles with 2 equal teeth, crossing when closed (Fig. 177); occiput separated from gena/postgena by vertexal trabecula, a thick bar of cuticle (in photographs) extending transversely across posterior surface of head to posterior apex or each supraorbital sulcus, the latter extending ventrally at least to level of occipital foramen (Fig. 165); in scanning electron micrographs the cuticular bar appearing as a thin sulcus (Fig. 173); mesophragma projecting slightly into gaster (Fig. 171); gt 1 about same length as each following tergum (Fig. 183).

Discussion. Callodicopus belongs to the Alaptus group of genera, together with Alaptus, Dicopomorpha, and Dicopus though it appears to be a link with the Camptoptera group of genera. The main feature that supports place- ment in the former group is the wide propodeal foramen with the mesophragma projecting slightly through it into the gaster. However, the back of the head closely resembles members of the Camptoptera group of genera because of the presence of a median vertical coronal sulcus (Figs 165, 173).

The first Callodicopus species known in America north of Mexico is described below. Several other specimens were examined but do not seem to have the back of the head with a thick transverse bar of cuticle (Fig. 165) extending above the foramen from eye to eye; they may be species of Dicopomorpha . The limits of both genera need clarification.
