﻿EURYURID MILLIPEDS — HOFFMAN 239 



Range. — The species is known to occur from west Florida north 

 through Georgia (Indian Springs), Alabama (Auburn), and Ten- 

 nessee to extreme northern Kentuclry (Crittenden). 



Loomis was misled into describing falcipes by a misunderstanding 

 of Bollman's statement that the upper branch of the male gonopod 

 of australis is five times as long as the lower. This refers to the 

 branches in their position on the living animal. In Loomis' descrip- 

 tion and figure, the gonopod is reoriented so that the actual position 

 is reversed. Bollman's type of au.Hralis has been discovered at the 

 National Museum and its gonopods verify this idea, matching per- 

 fectly with the figure of falcipes. 



Genus PHINOTROPIS Chamberlin 



Phinotropis Chamberlin, Bull. Amer. Mus. Nat. Hist., vol. 78, p. 499, 1941. 

 (Genotype: P. tidus Chamberlin.) 



Range. — Northwestern Brazil, northeastern Peru, Ecuador. 



Species. — Phinotropis acuticoUis (Attems), 'braueri (Carl), halo- 

 notus (Attems), mammatus (Attems), froreri (Chamberlin), tidus 

 Chamberlin. 



The original description of Phinotropis is as follows : "This genus is 

 erected for the species described below in which the male gonopods 

 differ from those of Thrinoxethus in having the major distal branch 

 entire and distally acute like the minor branch." 



Thnnoxethus was characterized as follows: "Agreeing in general 

 structure with Polylepiscus but differing in the form of the gonopods 

 of the male. In these there are two distal branches of which one is 

 distally acute and the other, larger one, furcate at its distal end . . ." 



Insofar as these two diagnoses alone go, it is obvious that Phino- 

 tropis is identical with Polylepiscus as used by Attems and others. 

 However, with the restriction of the latter name to Guatemalan species 

 having three terminal processes on the male gonopod, Chamberlin's 

 name becomes available for the South American forms and must be 

 used, although originally a synonym. 



Polylepiscus roreri Chamberlin, from Trinidad, is Imown only from 

 the female type specimen, and probably pertains to another, possibly 

 new, genus.
