REVISION OF GENUS FURNARICOLA — CARRIKER 



Furnaricola triangularis, new species 



415 



Figures 13, 14, 22a 



Holotype female and allotype male adults, from Lepidocolaptes 

 souleyetii lineaticeps (Lafresnaye), collected by the author at El 

 Conejo, Sierra Perij^, Colombia, March 18, 1945 (Carriker type 

 no. 792). 



Diagnosis: Head practically an equilateral triangle, with narrow 

 frons, rounded temples, and wTth anterior plate and its supporting 

 carinae extending for half the length of plate beyond the tips of the 

 preantennary carinae. 



Pleurites heavily pigmented and with their heads forming a reverse 

 hook; spiracles large and hyaline. Basal plate long and much wider 

 at distal end; both paramera and endomera differ in details. Repre- 

 sented by holotype female, allotype male, and three male and one 

 female paratypes. Three females from Lepidocolaptes affi/nis 

 sneidemi, collected at Urr^o, Antioquia, cannot be separated from 

 triangularis. When the male from L. a. sneidemi is kno\vn it may 

 show differences in the genitalia which would separate it from 

 triangularis, but for the present it seems best to make no attempt 

 to separate it subspecifically. 



Measurements of the types of F. hirsuta picirostris and F. triangularis 

 are as follows: 



Furnaricola fuliginosa fuliginosa Carriker, 1963 



Furnaricola fuliginosa Carriker, 1963, Ann. Mag. Nat. Hist., ser. 13, vol. 5, 

 p. 467, figs. 34-35. 



Host: Dendrocincla j. fuliginosa (YieiHot). Types in British 

 Museum (Natural History). 



In this species the head is similar to that of certhia, but very much 

 smaller; the anterior plate extends farther beyond the preantennary 

 carinae and is nari'ower; thoracic segments same shape as in guttata 

 Carriker, but male genitaUa smaller and with both basal plate and 

 endomera quite distinct in structure.
