Neotraginops Prado

Neotraginops Prado, 1973: 504 .

Type species: Traginops clathratus Hendel, 1909: 52 (original designation).

Diagnosis (adapted from Prado 1973 and Hernández-Ortiz & Dzul-Cauich 2014). Head with a large ocellar tubercle, covered by setulae. Ocellar setae divergent; postocellar setae divergent, approximately half length of ocellar setae; inner vertical setae convergent; outer vertical setae divergent. 3 pairs of fronto-orbital setae present, the anteriormost seta inclinate and posterior setae reclinate. Lunula with a velvet black triangular spot. Antenna short with third antennal segment rounded apically. Arista pubescent, basal portion orange, distal portion dark brown. Chaetotaxy of the thorax as follows: 3 postpronotals, 2 notopleurals, 1 supra-alar presutural, 2 supra-alar postsuturals (anterior pair weak), 2 postalars, 1 intrapostalar, 4 dorsocentrals (anterior pair presutural and remaining three postsutural), 1 acrostichal, 2 propleurals, 3 katepisternals, 2 scutellars with scutellum setulose on disc. Wing brownish with reticulated pattern of hyaline spots; Sc nearly complete, fading distally; R 2+3 and R 4+5 slightly divergent apically; R 4+5 and M 1 slightly convergent but becoming parallel at apex; crossvein dm-m straight. Apical ventral seta on mid tibia twice as long as preapical dorsal seta; one short preapical dorsal seta present on all tibiae.

Comments. Within the subfamily, the genus seems to belong to a clade that also includes Paratraginops Hendel and Traginops . This is especially suggested by the elevated ocellar tubercle, a uniquely derived feature in the family. Within this clade, Neotraginops is probably a sister group to Traginops , as suggested by the membranous portion of the phallus subdivided into a pilose hemispherical capsule and a set of ventrally projecting membranes. The pubescent arista and a straight M 1 separate Neotraginops from Paratraginops . Neotraginops differs from Traginops mainly by the presence of two propleural setae and differences in the male terminalia. The keys presented in Gaimari (2007, 2010) and Gaimari & Mathis (2011) can be used to identify Neotraginops leading to the following key to species.
