and lobed dorsally and ventrally. Tergites and sternites with but a single plate. The interseg- 
mental furrows, dorsally, are marked by quite conspicuous, small sclerotic areas which are quite 
characteristic of the species. 
Genitalia (Fig. 24D) with the basal plate long and slender, reaching almost to the base of the 
abdomen; pseudopenis articulating by the tips of its arms to the arms of the basal plate; preputial 
sac indistinct and beset with very minute teeth. 
Female (Fig. 23). Length 1.2mm. In form of head and thorax, except for the antennae, very 
similar to the male. Abdomen with the tergites and sternites undivided. The intersegmental 
sclerotic areas, which are conspicuous in the male, are much reduced. Gonapods (Fig. 24B) 
with a small, two-toothed lobe on the inner face. 
Nores. I cannot place this species with any described form. It is ap-
