Oxylipeurus ruficaudatus, new species 

 Figures v:12,17 



Holotype female from Ortalis rujicauda Jardine from Venezuela (in 

 USNM). 



Diagnosis: With the exception of angustifrons (1.82), it is the smallest 

 known species of the genus (length 1.96) but near chiniri (1.99), all females. 

 All other species are more than 2.00 in length. However, the shape and 

 proportions of the head differ considerably from both, all measurements 

 are greater than in chiniri, and temples narrower than in angustifrons (.37 

 against .40). 



It most closely resembles the female of chiniri but the corrugations of the 

 transverse carina of the frons are much coarser, and the preantennary 

 carinae much narrower; there are four small hyaline pustules along the 

 inner margin of the postocular carinae, absent in chiniri, and 3 long and 2 

 short transverse setae are on each clasper, with 6 short setae on claspers 

 of chiniri. 



Measurements are as follows:
