REPORT UPON ECTOPARASITES OF MAMMALS 1037 
_ Male. Differing from the male of 7’. congoensis apparently only in the character of the genitalia 
(Fig. 244A). In this species the arms of the basal plate articulate with the sides of the arms of the 
pseudopenis and the endomeres are completely divided (Fig. 24C). The basal plate is even longer 
than in 7’. congoensis, extending actually into the metathorax. 

Text Figur 24. — T'richodectes congoensis n. sp.: 
B, gonapod; D. detail of genitalia of male; EF, genitalia 
of male. T'richodectes baculatus n. sp.: A, genitalia of 
male (only part of basal plate shown); C, detail of 
genitalia of male 
Notes. In view of the very close evident relationship of this form with 7’. 
congoensis, it is possible that the two females mentioned may belong with these 
males. But it is impossible to tell. If they do the females of the two species can 
hardly be distinguished. Further collecting may throw some light on the matter. 
As far as the male is concerned, they must be regarded as distinct.
