Key to the genera Ulmeritoides View in CoL View at ENA and Ulmeritus (modified from Salles & Domínguez 2012)

The key to male imagos of Ulmeritoides and Ulmeritus presented by Salles & Domínguez (2012) was modified to include the two new species here described and Ulmeritoides passorum Gama Neto & Hamada, 2014 , as below.

1. Vein Sc of hind wings 9/10 length of wing; membrane of wings with dark maculae at cross veins (fig. 2 in Domínguez 1991); apex of each penis round, lobe with ventral digitiform projection (fig. 3 in Domínguez 1991)................ 2 Ulmeritus View in CoL
