TACHINIDAE OF ORIENTAL REGION 119 



Apical scutellar setae horizontal. Mid tibia with two strong ad setae of which the 

 proximal one is slightly weaker than the distal one. On vein M distance between 

 r-m and m-cu subequal to that between m-cu and the bend. Smaller forms, 

 length 3-5-6-0 mm ...... BESS A Robineau-Desvoidy 



Wing with last section of Cu 1 subequal in length to or shorter than m-cu 



AUSTROPHOROCERA Townsend 



Wing with last section of Cu l very much longer than m-cu . CHETOGENA Rondani 



Ocellar setae very strong. Bend of vein M with a very long conspicuous A/ 2 fold. 

 Frons of $ with upper pair of reclinate orbital setae not twisted outwards and none 

 of the frontal setae reclinate ....... EXORISTA Meigen 



Ocellar setae absent or minute and hair-like. Bend of vein M usually with almost 

 no definite M % fold. Frons of $ with upper pair of reclinate orbital setae twisted 

 outwards as well as backwards, and with all or at least the uppermost pair of 

 frontal setae strongly reclinate ......... 9 



Vibrissae inserted on a level with epistomal margin. <$ with one pair of reclinate 

 orbital setae, 9 with two pairs (upper pair very small), both sexes with frontal 

 setae strongly reclinate and not clearly differentiated from the reclinate orbitals. 

 Bend of M with distinct elongate fold. Eyes haired. 0* with slender shining 

 black abdomen on which pale pollen bands confined to extreme tergite bases, the 

 T5 very small in relation to T4 (superficial appearance very like Aplomya metallica). 

 Intermediate abdominal tergites (both sexes) with discal setae PHORCIDELLA Mesnil 



Vibrissae inserted well above the epistomal margin, q" and $ with two pairs of 

 reclinate orbital setae and the frontal setae not reclinate (except for uppermost 

 pair in $, which resemble and are not clearly differentiated from reclinate orbitals). 

 Bend of vein M with scarcely any fold. Eyes haired or bare. Both sexes with 

 broad ovate abdomen that is extensively pale pollinose, o* abdominal T5 not 

 noticeably small (q* without resemblance to Aplomya species but with extremely 

 sturmiine facies). Intermediate abdominal tergites without discal setae (at most 

 with some irregular stiffened setulae among the general hairing) 



EOZENILLIA Townsend 

 [This genus is extremely like Neophryxe Townsend from Japan, with which it 

 ought possibly to be synonymized.] 



Tribe ETHILLINI 



This is a small Old World tribe containing a diversity of little known Goniinae 

 that possess little more in common than the fact that the lower calypter is bent 

 downwards on its outer surface (a feature found also in some Winthemiini and some 

 Carceliini). The group was proposed by Mesnil (1944a) and has been recognized 

 by later workers such as Verbeke (1962a; 19626) and Crosskey (19736), but it is 

 almost certainly not monophyletic. Ethilla Robineau-Desvoidy, the type-genus 

 of the tribe, parasitizes Lepidoptera and has a rather winthemiine facies but Phoro- 

 cerosoma Townsend and its obvious allies attack Orthoptera and have a rather 

 distinctive facies of their own suggesting that they could better be treated as a 

 separate tribe (for which the name Gynandromyiini is already available). For 

 present purposes the tribe is accepted in the current sense, but it might be useful 

 to call attention to those characteristics of Phorocerosoma, Gynandromyia Bezzi, 

 and allied forms that make them rather distinctive among the Goniinae as a whole. 



This group of so-called genera has the inner vertical setae convergent and crossing 

 before their apices, the outer vertical setae reduced or absent in both sexes, the
