PARATYPE (male) labeled: (a) “Vila Oliva / 19 - 2 - 52”; (b) Rio Grande do Sul / 3886 / Pe Buck Leg.” (c) “ PARATYPUS / Ulosonia laevicollis n. Sp. / det H.

Specimens should be in the Hungarian Natural History Museum, the Muséum National d’Histoire Naturelle and the Zoologische Staatssammlung.
Additional material examined: (8 males, 5 females): BRAZIL: 4 males, 3 females. TB# 20158-20159; mx_id 48027 (NHMB); BRAZIL: Rio de Janeiro: 2 males. TB# 20160-20161 (NHMB). BRAZIL: Rondônia: 1 female. TB# 20156 (FSCA). country not specified: 2 males, 1 female. TB# 20152-20154 (BMNH).
Diagnosis: The clypeal horn of this species is short, conical and projects forward. The supraorbital horns are long, projecting initially perpendicularly and then bending to point anteriorly. They are also thinnest at the base and become more thick away from the head. The punctures on the pronotum are almost exclusively fine. The head of the male is smooth, whereas the head of the female has larger punctures, but not larger than one eye facet. This species is larger than others of this genus (11 mm). The female has similar characters as the male, except without horns (Fig. 29).
Redescription: Male. Size: 9—11 mm; 3—4 mm.
Head. Clypeal horn short (4:1; 5:0); equal thickness to supraorbital horns (7:1); produced forward (8:0); finely punctate (9:1). Supraorbital horns long and thick (10:1; 11:1); thinner proximally and thicker apically; produced perpendicular to head (13:1); bent inwards toward each other (12:1); strongly bent to point anteriorly (14:2); finely punctate (15:1). Antennae with stellate sensoria (22:0). Third antennomere less than 1.5 times size of fourth and more than 1.5 times size of second (18:1; 19:2). Vertex and frons not punctate (26:0; 28:0).
