Johnrichardia Perez­Gelabert & Thompson , gen. nov.

Type­species: Johnrichardia vockerothi Perez­Gelabert & Thompson

Head: Clypeus well developed; arista pubescent; frons normal, not produced; without orbital seta; with only medial vertical seta and proclinate ocellar seta; occiput narrow in lateral view on dorsal 1/2 (fig. 2).

Thorax: Postpronotum with distinct, but short and weak seta; propleuron with short pile dorsad to procoxa; notopleuron with 2 long strong setae; scutum with 1 long strong supra­alar seta, 1 long strong postalar seta, 1 long strong dorsocentral seta slightly anterior to scutellum and aligned with postalar seta, 1–2 short weak scapular setae on anterior margin of scutum, with a row of distinct pili running long dorsocentral line; scutellum with 1 pair subapical seta; anepisternum with 1 strong and 1 weak posterodorsal setae, with some pile on ventral posterior portion; katepisternum with a few scattered pili dorsally, longer and denser pili anterior to mesocoxa; anepimeron with row of short pile on posterior 1/2; meron bare; katatergum with long pili dorsad to spiracle; metasternum pilose; postmetacoxal bridge complete, broad.

Etymology. The name, Johnrichardia , is an arbitrary combination of letters created to be similar to the first names of the distinguished dipterist, John Richard Vockeroth. The name is to be treated as feminine.

Johnrichardia is readily distinguished from all other richardiids by the loss of orbital and lateral vertical setae. The large size (15 mm) is also unusual as most richardiids are less than 10 mm long.
