(sometimes smaller setulae in addition), q abdomen with fascicles of long dense 



hair on the venter of T4 and T5 ..... . SIMOMA Aldrich

 node of /? 4 ■ 5 with a row of three or more setulae

on almost their whole height. Basal node of i? 4+5 with a single setula 



ELODIMYIA Mesni 



BUQUETIA -group 



Head shape normal. Eyes bare or almost so. Facial ridges bare, not visible in profile. 

 Parafacials completely haired. Frontal setae slightly reclinate. Two pairs of reclinate orbital 

 setae. Upper occiput flat, with black setulae behind the postocular row. $ without proclinate 

 orbital setae. Arista normal, basal segments short. Humeral callus with three setae standing 

 in line, innermost one sometimes hair-like. 3 + 3 dc setae. Three stpl setae. Wing cell 

 R b open. Bend of vein M widely obtuse and slightly rounded, no trace of M 2 . Second costal 

 sector haired ventrally- Mid tibia with one ad seta that is usually accompanied by some 

 smaller ad setulae basad of the main seta. Hind tibia without pd preapical seta. 



Included genus. Buquetia Robineau-Desvoidy. 



This genus, which appears still to be monotypic, occurs in the southern Palaearctic 

 Region (e.g. Mediterranean islands, Middle East) and does not form an element 

 of the Oriental fauna proper: it is included here because of its occurrence in Pakistan. 



The affinities of Buquetia appear uncertain. Although it runs out with A neogmena- 

 group in the foregoing key because of the presence of only three post dc setae (a 

 relatively uncommon condition in Eryciini) there is almost certainly little or no 

 relationship with this group. The adult facies of the genus resembles that of the 

 Australian genus Chlorogastropsis Townsend (which also has haired parafacials, 

 another relatively uncommon feature in Eryciini), and that of Nealsomyia, and 

 Buquetia is perhaps phyletically close to these genera. There is a particularly 

 close resemblance amongst these genera in the conformation of the head, the short 

 antennae and vibrissae somewhat above the epistomal margin, and in the abdominal 

 shape. 



in Buquetia the thorax and abdomen are rather evenly covered with thick greyish 

 yellow pollinosity, and the flies therefore have a very different appearance from 

 the other Oriental forms with three post dc setae (Aneogmena-group) in which the 

 colour is generally black with silvery pollinose abdominal bands.
