Furnaricola certhia certhia Carriker, 1963 



Figures 2a, 3, 4 



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

 p. 465, figs. 28-30. 



Host: Dendrocolaptes c. certhia (Boddaert). (Carriker type no. 701, 

 in British Museum (Natural History) ; male and female paratypes in 

 Carriker collection.) 



One of the larger species, with female much larger than male; 

 the frons wide (.105 in both sexes) ; preantennary portion of head with 

 margins strongly concave; basal plate wide (.11 at base); endomera 

 short and wide (.06 X .046) ; paramera rather long (.11), with apical half 

 slender and curving inward, and with outer margins concave medially 

 (see fig. 4). 



Specimens from D. certhia hyleorus and D. c. colombianus, in the 

 author's collection, differ sufficiently from F. certhia to merit sub- 

 specific rank and are described below. 



Measurements of F. tergalis, new species, and F. certhia Carriker 

 are as follows: 



Furnaricola certhia colombiana, new subspecies

Holotype, male adult, from Dendrocolaptes certhia hyleurus Wetmore, 

 collected by the author at Volador, Dept. Bolivar, Magdalena Valley, 

 Colombia, May 19, 1947 (Carriker type no. 787). 



Diagnosis: This race of certhia is closely related to the nominate 

 form from British Guiana. The measurements are very close, but the 

 frons is wider (.14 against .105) ; the prothorax is slightly smaller; the 

 basal plate narrower (.08 against .11) ; endomera longer and narrower, 

 and the paramera are very differently shaped (see fig. 5), having the 

 wide, basal portion very long and parallel-sided, with the tips very 

 short, slender, and slightly incurved. 



Represented by the male holotype and one male paratype.
