NOTHOCOTUS PARVITHORAX PARVITHORAX Carriker 
FIGURE 9, f, g 
Nothocotus parvithoraz CARRIKER, Lice of the tinamous, p. 104, pl. 11, figs. 3-3b, 
19386. (Host: Nothocercus bonaparti.) 
This species was described from one male and two females. The 
types are not available for comparison with the series of specimens 
taken on the type host, collected in the Sierra Perijaé, Colombia, in 
1941, but a female paratype is still in my collection. 
This series is exceedingly uniform inter se and does not agree in all 
respects with the figures of the types of parvithoraw, nor does the 
female paratype agree with the published figure. The temples are 
not angulated in either sex, but rounded, almost exactly the shape of 
the temples in V. p. subsimilis. The other difference is in the shape 
of the paramers, which have the tips bent inward somewhat as in 
subsimilis, but the bent portion is not concave, nor are the tips taper- 
ing as in subsimilis, An error was probably made in preparing the 
published drawings of the types, since all the other details of the 
genital armature in the Colombian insects are as figured for the 
species. 
New figures are herewith given of the head and genital armature of 
the Colombian insect. Their measurements are very close to those 
of the types, and until the types can be compared with the Colombian 
series it seems best to identify them as WV. p. parvithorax. In view 
of the more extensive knowledge acquired of this group of Mallophaga, 
it seems best to make WV. subsimilis a subspecies of parvithoran.
