Genus Furnaricola Cariiker, 1944 



Furnaricola Carriker, 1944, Bol. Ent. Venezolana, vol. 3, no. 2, p. 83. 



Type species : Furnaricola acutifrons Carriker. 



The genus was fully and accurately characterized in the original 

 description and in that respect needs no further comment. 



At the time the genus was established 8 species were placed in it, 

 5 from the Furnariidae, 2 from the Dendrocolaptidae, and 1 from the 

 Formicaridae. Since then (in a paper published in 1963) the 

 author has described 3 additional species from the Dendrocolaptidae. 

 The hosts of the species from the Formicariidae, described in 1944, 

 were under suspicion for some time, since I was under the impression 

 that the genus might possibly be restricted to the Furnariidae and 

 Dendrocolaptidae. 



Later collecting has yielded numerous species of the genus, not 

 only from the above-mentioned two families, but several more from 

 the Formicariidae, and also, most unexpectedly, specimens were 

 secured from two species of Pipridae (Manakins) and two from the 

 genus Scytalopus (Rhynocryptidae), the latter being the first record 

 of the taking of Mallophaga on this family of birds. Much care was 

 taken in checking these host records, but there seems to be no reason- 

 able doubt of their accuracy, especially those from Scytalopus. 



A single female was taken on Pipra pipra comata (central Peru) 

 and 1 female from Pipra caeruleicapilla (south Peru). They are 

 typical of the genus but of a slightly distinct type, possessing certain 

 special characters. 



Two females were taken on Scytalopus magellanicus affinis (north 

 Peru) and 2 females on S. m. canus (Colombia). The latter two also 

 represent a slightlj" different type of insect. From the Formicariidae 

 the following were secured: 2 pairs from Myrmeciza immaculata, 1 

 female from M. laemosticta pallida, and 1 female from Pyriglena picea. 

 All are typical Furnaricola and prove conclusively that the genus 

 is parasitic on at least five families of the Passeriformes and cannot 

 possibly be congeneric with Rallicola. 



In the present paper 4 species from the Dendrocolaptidae, 5 from 

 the Furnariidae, 2 from the Formicariidae, 2 from the Pipridae, and 2 

 from the Rhynocryptidae are described as new to science. There 

 is also another species now in press, from Venezuela, which will be 

 noted on succeeding pages. 



This is one of the controversial genera of Mallophaga, which, in 

 the 1952 "Checklist of Mallophaga," was treated as a synonym of 

 Rallicola.
