TACHINIDAE OF ORIENTAL REGION in 



Two sternopleural setae. 2 + 3 dorsocentral setae. Presternum with several strong 

 hairs each side (very rarely only one hair on one side), prst ia seta absent. Bend 

 of vein M abrupt (not forming a gentle even curve) and remote from wing margin, 

 distance from bend to margin at least as great as that between bend and m-cu

Three sternopleural setae. 3 + 3 dc setae (middle prst dc sometimes weak). Prester- 

 num with one long strong setula on each side, prst ia seta present. Bend of vein 

 M evenly curved and nearer to wing margin than to m-cu. [Africa and Palaearctic 

 Region] METACEMYIA Herting 



Tribe NEAERINI 



The systematic position of this small tribe is uncertain and it ought possibly to 

 be placed (together with the Siphonini) in the Tachininae rather than the Goniinae. 

 In the Oriental Region it is so far known to be represented by only two genera. 

 The main features that these have in common are as follows. 



Eyes almost bare. Both sexes with very strong outer vertical setae and two pairs of pro- 

 clinate orbital setae. Ocellar setae strong. Parafacials bare. Facial ridges setulose only 

 on the lowermost quarter or so. Genal dilation and outer edge of postbucca with unusually 

 strong bristly vestiture. Antennae broad and heavy, arista thickened on more than half 

 its length and with the second segment elongate. Propleuron bare. Humeral callus with 

 three setae in line. The pra seta small. Distinct downcurved prostigmatic seta present in 

 addition to the normal strong upwardly directed prostigmatic seta. Subapical scutellar setae 

 strongly convergent, often crossing at the apices. Basal node of /? 4 + ; with one very strong 

 seta, usually accompanied on dorsal surface by one or two smaller setulae; second costal sector 

 haired ventrally. Mid tibia with one ad seta and with a submedian v seta; hind tibia with an 

 enormous pd preapical seta that is stronger than the d preapical seta. Intermediate abdominal 

 tergites without discal setae. 



It is of interest to note that in both the Oriental neaerine genera, and in some 

 other genera of the tribe, there is a moderately well developed downwardly directed 

 prostigmatic seta as well as the normal prostigmatic seta; this downward prostig- 

 matic seta resembles the downwardly directed prostigmatic seta found in the genus 

 Peribaea (tribe Siphonini), but in the latter both prostigmatic setae are equally 

 strongly developed. An arrangement of two equally strong prostigmatic setae with 

 one upward and one downward seems only to occur in Peribaea, the lower seta in 

 neaerines apparently being always obviously weaker than the upper one. 



The Neaerini are parasites of larval Lepidoptera. The only host known from 

 within the area covered by the present work is the tortricid Griselda hypsidryas 

 Meyrick which is parasitized by Phytomyptera minuta in Pakistan.
