Townes' (1970) description and key characters for this genus are partly inaccurate and 

 misleading. In making his description and choosing the characters to use in his key to the genera 

 of the Phygadeuontina, Townes appears to have neglected the type-species of 

 Ceratophygadeuon and based his description and key mainly upon a group of species (which I 

 will call the perditiis group) whose members are at least in part parasitic upon the larvae of 

 Stratiomyidae. However, even the males of the perditus group (and occasionally the females as 

 well) often have two median apical teeth on the clypeus instead of the "single median tooth" 

 described by Townes. Viereck described Ceratophygadeuon as having the "clypeus bituberculate 

 at [the] ape.x." which roughly agrees with the two specimens of the type-species I have seen and 

 with Townes' figure of that species (One of the specimens is like Townes figure in having what 

 could be described as a single bifid clypeal tooth). In addition to its sharp facial tubercle (whence 

 the name Ceratophygadeuon), the type-species has a rather unusual mandible which is short, 

 very broad basally, narrowed very little from base to apex, and transversely concave on its 

 outer surface; in the two examined specimens, both of the mandibular teeth have been worn 

 down, but probably were almost equal in length. In species of the perditus group, the mandible 

 is long, narrow, rather strongly tapered somewhat internal to the upper tooth, which seems to 

 agree with what little Townes says concerning the mandible of Ceratophygadeuon. I do not 

 know if either of the names Remonzia or Euremonzia would be applicable to members of the 

 perditus group.

 which appears on p. 37 of the "Additions" was rejected in favor of aciculatus by 

 Provancher (1889) in the errata (p. 476) of the same work.

SUBTRIBE STILPNINA 



So far as is known members of this subtribe are parasites of cyclorrhaphous Diptera, oviposit- 

 ing into late-instar larvae and emerging from puparia.
