Proneoglaphyroptera. Meunier, Mon. Mycetoph. etc. p. i58 (1904). 
Characters. — The antennae of the male longer than the head and thorax taken together, of the 
female somewhat shorter; basal joints differentiated, the first flagellar joint more than three times as 
long as wide, apical joint longer than the preapical. Wing elongate oval; costa produced beyond the tip 
of the radial sector; subcostal vein ends in the costa beyond the middle of the elongate basal cell R; 
base of the radial sector nearly transverse in position and less than one-third as long as the long R-M 
crossvein which is longitudinal in position and forms apparently the beginning of the sector; the petiole 
of the media about as long as the R-M crossvein; fork of the cubitus under or distad of the proximal 
end of the crossvein (PI. 5, Fig. i I).
