Description
Atherhagiox, new genus
DIAGNOSIS: Differs from living and extinct athericids by having base of fork of R 4+5 significantly proximal to level of apex of cell d (i.e., cell d is quite long). Further, veins M 1 and M 2 sinuous as in Galloatherix; like this genus and Sinocretomyia and Palaepangonius, R 2+3 also sinuous, but its apex not in contact with apex of R 1. Atherhagiox further differs from Sinocretomyia by the reniform (vs. ovoid) basal flagellomere.
TYPE SPECIES: Atherhagiox ambiguum, new species.
ETYMOLOGY: The generic name is a combination of the two names of type genera of Athericidae and Rhagionidae — Atherix and Rhagio —and refers to the hybrid set of characters of the new genus. The gender of the name is neuter.
COMMENTS: Atherhagiox have similarities with certain Rhagionidae, and the boundaries between this family and Athericidae have historically been vague. Like the rhagionid genus Symphoromyia, the new genus has a reniform basal flagellomere with an aristalike terminal section of the flagellum and a sinuous R 2+3; both genera also have 0-2-1 tibial spurs. Other similarities are plesiomorphic: a vein R 2+3 that does not converge with or approximate the apex of R 1; suprametacoxal pit (found in all athericids except Dasyomma) is lacking; cerci 2-segmented, and female terminalia telescoping. However, like athericids and unlike rhagionids, Atherhagiox have a deeply excised, lappetlike basicosta and arched palps. Mandibles are present in the female (these are absent in most Rhagionidae with the exception of Symphoromyia).
