STUDIES IN NEOTROPICAL MALLOPHAGA—CARRIKER 207 
are much less developed and are broken medially, while in seaxsetosus 
they are entire. The chaetotaxy of the abdomen is also distinct, there 
being more hairs on secundus, while they are mostly longer and 
slenderer; the shape of segment VII is also different. The male geni- 
talia, while of the same general pattern as in sewsetosus, differ de- 
cidedly as to proportions and detail, especially in the basal plate and 
paramers (see fig.). In the female the genital plate, as well as the 
posterior margin of segment VII, is differently shaped. 
The new race is represented by four males and five females, taken on 
three individuals of the host, collected at Padilla and Samaipata, 
Bolivia. 
Subfamily ORNICHOLACINAE Carriker 
Genus HEPTAGONIODES Carriker 
Heptagoniodes CARRIKER, Lice of the tinamous, p. 166, 19386. [Genotype: H. mira- 
bilis Carriker—Heptagoniodes agonus (Nitzsch).] 
This genus was created solely on the characters of the male, the 
female being unknown at that time, or rather the two sexes were known 
but not associated with each other; therefore it becomes necessary to 
amend the generic diagnosis to include the characters of the female. 
Sexes strongly dimorphic, not only in the shape of the antennae, but 
in the shape of the whole head, the female strongly resembling both 
sexes of Kelloggia, especially the female, having the temples expanded 
laterally and posteriorly, with the front narrow and rounded and with 
the sides of head straight and strongly divergent; sides of head bifur- 
cated in the female, as in both sexes of AHelloggia; antennae of female 
short and slender, but with first segment considerably swollen and 
rounded and attached on the wnder side of the head; thoracic segments 
and abdomen practically the same in both sexes, while the female is but 
slightly larger than the male. 
Note on synonymy.—Now that the true identity of Gontocotes agonus 
Nitzsch has been established, it is possible to clear up the synonymy of 
the various genera that have become involved with it by previcus 
authors. | 
Taschenberg erected the subgenus Lepidophorus in 1882 and placed 
in it Goniocotes agonus Nitzsch and L. coniceps, sp. nov. | = Hypocryp- 
turellus coniceps (Taschenberg) |. In 1916 Harrison made the genus 
Ornicholaw Carriker a new name for Lepidophorus Taschenberg 
(name preoccupied), which was totally unwarranted, because no 
species placed in Ovnicholax was included by Taschenberg under 
_ Lepidophorus. 
In 1986, on page 171 of my “Lice of the Tinamous,” I called atten- 
tion to this fact, and designated Kelloggia Carriker, 1903, as the new 
name for Lepidophorus, which also was in error, being contrary to the
