1032 REPORT OF THE HARVARD AFRICAN EXPEDITION 

Text Figure 19. — Trichodectes lindfieldi Hill, male 
and female 
Associated apparently with the uterus is a curious chitinous sac (Fig. 20@), 
which is quite strongly sclerotic and is of a cylindrical form. 
This species has a very close relative in the next to be described. 
Trichodectes dendrohyracis, new species 
Text Fig. No. 20 
MaTEeRIAL EXAMINED. Three males and three females from Dendrohyraz 
validus, Mt. Kilimanjaro (United States National Museum). Holotype a male. 
Male. — Length 1mm. In general so closely related to T’. lindfieldi (as here understood) that 
the general figure of the latter will do for this. The distinctive features appear in the genitalia 
(Fig. 20B) which lack the large teeth on the preputial sac and which have the penis developed into a 
conspicuous, sclerotic tube. 
Female. — Length 1 mm. Practically identical with the female of 7. lindfieldi except that 
associated with the uterus is a sac, or other structure (Fig. 207’) of curious and apparently constant 
form, which replaces the cylindrical sac found in 7’. lindfieldt. 
Nores. Although this species is certainly very close to T. lindfieldi, I am 
convinced that the two must be recognized as distinct. The association of the 
male and female here regarded as dendrohyracis is on the basis of their occurrence 
together and their size.
