TAXONOMY Of MUSCOIDEAN FLIES — TOWNSEND 4J 



Facial plate below vibrissal angles never receding conspicuously, the oral 

 margin always more or less prominent, the facio-peristomal profile in con- 

 sequence never evenly and gently convex ; vibrissal angles approximated 

 to oral margin and never placed much higher above its median portion 

 than length, of second antennal joint, distinctly below two-thirds point of 

 face, the mesofacial plate elongate, never very strongly constricted, if 

 constricted at all the constriction is close to oral margin; antennae usually 



long (Tachinid-Muscid Stem)

Vibrissas and macrochaetae absent; mouthparts wanting or rudimentary, non- 

 functional Family CEstrid.e 



Vibrissas and macrochaetae present, mouthparts functional. 



Family Macronychiid.e 

 B 

 Macrochaetae developed, or if not (Gymnosomatinae only) then the more or 

 less red abdomen highly swollen or inflated and covered with very short, 

 fine, black, bristly hairs; ovipositor never Musca-like. 



Family Tachinid.£ 



Macrochaetae not developed, or if so (Reinwardtia only) then no fronto- 

 orbital bristles present and ovipositor integumental, long and Muscohlike ; 

 abdomen never swollen or inflated Family Muscimj 



The series Aschiza (Becher and Brauer) includes the Phoridae, 

 Pipunculidae, Platypezidae, and Syrphidae. The series Schizophora 

 (Becher and Brauer) includes all the rest of the Cyclorrhapha. 



The section name Pupipara might well be replaced with Nym- 

 phipara (Reaumur), which has priority. The section Myodaria 

 (Robineau-Desvoidy) corresponds to the Eumyidae of Brauer, and 

 to the Muscoidea of Coquillett plus the Conopidae. 



The subsection Holometopa (Brauer) includes the Malacosomse, 

 Palomydae, Phytomydas, etc., of Robineau-Desvoidy, and corre- 

 sponds in the main to the Acalypteratae of authors plus the Cono- 

 pidae. The subsection Schizometopa (Brauer) corresponds in the 

 main to the Calypteratae of authors, not of Robineau-Desvoidy. 



The super family Anthomyioidea (Townsend) corresponds to the 

 Mesomydae of Robineau-Desvoidy; and to the Anthomyiden of 

 Girschner minus most of the Muscinen of Girschner. The super- 

 family Muscoidea (Townsend) corresponds to the Creophilae of 

 Latreille, Westwood, Macquart ; to the Calypteratae of Robineau- 

 Desvoidy ; to the Muscaria Schizometopa (exclusive Anthomyiidae) 

 of Brauer and von Bergenstamm ; and to the Tachiniden of Girsch- 

 ner plus most of the Muscinen of Girschner. 



For detailed characters defining the suborders, series, and sub- 

 sections, see the works of Brauer, Becher, Williston, and Girschner.
