Neohaemato'pinus sciuri and related species 



1. N. sciuri Jaiicke apparently occurs on both European Sciurus 

 vulgaris and North American Sciurus carolinensis. At least, the 

 North American specimens are morphologically indistinguishable 

 from the European ones. This species is characterized by not having 

 the posteroapical prolongation on the basal antennal segment, and 

 by having a stout spinelike seta at the posteroapical angle (fig. 40). 

 Specimens have been examined as follows: From Sciurus vulgaris : 

 England. From Sciurus carolinensis: New York, Rhode Island, 

 Maryland, District of Columbia, Virginia, North Carolina, Georgia, 

 Florida, Mississippi, and Ohio. Also examined was one collection 

 supposedly from "southern fox squirrel," South Carolina. 



2. N. cognatus is found on Menetes herdmorei, Thailand. This 

 species is like sciuri in not having the basal antennal segment pro- 

 longed posteroapically. It is further characterized by having the 

 stout seta of the basal segment set in from the apex and by having a 

 tubercle on the venter of the basal antennal segment (fig. 39). Thai 

 specimens from M. herdmorei reported by Ferris (1923) as sciurinus 

 are referable to A^. cognatus.

 paratypes with same data as holotype. One male, sLx female para- 

 types from Hylopetes phayrei; Phukhieo, Ban Kaeng, Ban Lat,

Holotype deposited m the collections of the U.S. National Museum,

Diagnosis: This species is near sciuropteri (Osborn) from North 

 American Glaucomys. N. capitaneus is larger than sciuropteri (lengths : 

 sciuropteri cT 1.25-1.6 mm., 9 1.6-1.9 mm.; capitaneus cf 1.8-2.2 

 mm., 9 2.5-2.8 mm.). The thoracic sternal plate has the posterior 

 angles not produced into such long points in capitaneus and is wider 

 in relation to its length (compare figs. 59 and 60), The male genitalia 

 differ considerably in the 2 species. A*", capitaneus has the pseudo- 

 penis rugose and the penis extending only about one-fourth the 

 length of the parameres (compare figs. 54 and 56) ; and the terminal 

 lobes of the abdomen are not so weU developed as in sciuropteri. 

 Particularly in the female of capitaneus, typical paratergal plates 

 have small acute projections on either side of the apical setal bases. 

 The female genitalia have the lateral setigerous lobes of the eighth
