only with small teeth. The gonapods of the female (Fig. 15D) bear two or three 
tooth-like lobes on the inner face and the margin of the vulva is not at all toothed. 
In the male the anterior margin of the 
head is flattened, but not at all emargi- 
nate (Fig. 15B). The dorsal side of the 
head shows a faint tendency toward 
granulation, but there is no such pro- 
nounced development of this character 
as is to be seen in the next species.

Trichodectes granulatus, new species 
Text Fig. No. 16 
SPECIMEN EXAMINED. A single female from Procavia adolfi-friederici, Lu- 
lenga, BmLG1an Conao, March 2, 1927 (J. Bequaert). 
Female (Fig. 16A).— Length 1.75 mm. A slender species, resembling most closely 7’. serraticus 
and probably closely related thereto. Head somewhat longer than wide, with the anterior margin 
continuous and somewhat asymmetrical; posterior lobes strongly produced (Fig. 16B) and rather 
acute; antennae distinctly five-segmented; dorsal surface of the head distinctly granulate. 
Thorax cuneiform, the lateral margins of the prothorax and metathorax continuous and quite 
strongly divergent. Abdomen with pleural plates quite strongly developed on the first three seg- 
ments, more weakly so on the remainder, the third pair largest. Tergal and sternal plates strongly 
developed, one on each segment. Intersegmental membranes very distinctly granulate (Fig. 16C). 
Gonapods (Fig. 16D) with three tooth-like lobes on the inner face; margin of the vulva distinctly 
serrate. 
Notes. The asymmetry of the head, while quite marked in the specimen 
at hand may not be normal. The species is apparently most closely related to 
T. serraticus Hill.
