HEPTARTHROGASTER PARVULUS (Taschenberg) 
FIGURE 20, d 
Goniodes parvulus TASCHENBERG, Die Mallophagen, p. 88, pl. 1, figs. 4-4b, 1882. 
(Host: Tinamus robustus, Costa Rica=T'. major castaneiceps. ) 
Heptarthrogaster parvulus (‘Taschenberg) CARRIKER, Lice of the tinamous, p. 
134, pl. 20, figs. 1-lb, 1986. (Host: Tinamus major casianeiceps.) 
The types of this species were taken on a dried skin of “7¢namus 
vobustus,” from Costa Rica, according to Taschenberg. At that time 
the Caribbean and Pacific races of Ténamus major had not been sep- 
arated, and all were known as 7’. robustus, which name is now re- 
stricted to the birds from Mexico and Guatemala. Therefore, it is 
not possible to say (without knowing the exact locality from which 
Taschenberg’s host came) which race of 7. major is the true host of 
this parasite, since collecting had been done on both sides of the 
country by the three Germans von Frantzius, Hoffmann, and Ellen- 
dorf, who began working in Costa Rica about 1858, and whose collec- 
tions went to Berlin. They were notorious for the inaccuracy of the 
locality data on their skins, many being labeled “San Jose” that ob- 
viously could not possibly have come from there, and so we shall 
probably always be in some doubt about this point. 
The only Costa Rican specimens I have seen of this parasite are 
two females taken on T2namus major castaneiceps from Pozo Azul 
(on the Pacific side), and their measurements agree very closely with 
those given by Taschenberg. 
Additional material has been secured from the following hosts: 
Tinamus serratus ruficeps, Venezuela and Colombia; Tinamus major 
percautus, Mexico; and Tinamus t. tao, Colombia. These specimens 
have been carefully measured, together with those from 7’. s. serratus 
and the two females from Costa Rica. This series falls into two 
groups, the larger specimens coming from Tinamus t. tao and T. 
major percautus, the latter being slightly larger than the former; the 
smallest specimens are from 7’. s. ruficeps, with those from 7’. s. ser-
