Morphometric Differentiation

Morphometric analyses were carried out on five chromosomal races from the viatica group of morabine grasshoppers (Eumastacidae : Morabinae). The extent of intra- and interracial divergence was assessed and the population phenetics of a natural zone of hybridization between the 17 and 19- chromosome races of viatica was examined. Considerable evidence of intertaxon differentiation was noted. Conflicting evidence for introgression was found in the vicinity of the hybrid zone.

A Chain

Data are presented that indicate the presence of a hybrid zone between two chromosomal races of the endemic Australian spider Delena cancerides. Electrophoretic data verify the hybridising taxa as members of the Victorian telocentric race and a chain-carrying race. Evidence is presented that indicates the hybrid zone is of natural origin, as opposed to being the result of human introductions.
