Gelanes contrerasi (Khalaim & Ruiz-Cancino, 2019) comb. nov.

Probles (Euporizon) contrerasi Khalaim & Ruíz-Cancino, 2019: 210 [holotype female (UNAM), Mexico, Hidalgo, Huasca de Ocampo, Rancho Santa Elena, 20°06'N, 98°31'W, 2330-2535 m, Hueyapan River, 13.VI.2010, coll. A. Contreras R. et al.].

Remarks.

This species was recently described in the genus Probles based on a single female from the State of Hidalgo in Central Mexico. The species has a slender first metasomal tergite with glymma situated slightly behind the middle, thin and long foveate groove of mesopleuron and long thyridial depression (see figs 20-25 in Khalaim and Ruíz-Cancino 2019: 211), and therefore formally it runs to Probles . However, we consider that its unusually broad clypeus with a flat area centrally and highly polished genae and mesopleuron better correspond with the genus Gelanes (comb. nov.).

Gelanes contrerasi may easily be distinguished from another Mexican species, G. horstmanni Khalaim, by its genae constricted behind eyes in dorsal view (swollen in G. horstmanni ), slender antennal flagellum with 16 flagellomeres (robust, with 25 flagellomeres in G. horstmanni ), and longer basal area of propodeum and second metasomal tergite. In the key to the Nearctic species of Gelanes ( Horstmann 2013b: 238), G. contrerasi runs to G. incisus Horstmann and G. punctipleuris Horstmann in couplet 3, but differs from the both by having longer genae, propodeum with basal area very narrow and longer than the apical area, and longer second metasomal tergite.
