Renda glabrinotum sp. nov.

Type material ( 1 specimen). Holotype, female: “ SURINAME: Saramacca, West Suriname Road , 178 km WSW Zanderij Airport, 25 m, 4°59´6”N, 56°18´48”W, 12–14-VI-1999, Z. H. Falin, B. DeDijn, SUR1F99 o73, ex: flight intercept trap ” ( SEMC). GoogleMaps

Description. Total length 16.1 mm. Body densely setose; black, shining, with maxillary and labial palpi, labrum, apical antennomere and tarsi red.

Head. Oval, narrowed posteriorly (without posterior corners; similar to Fig. 15), 1.33x as long as wide; dorsal surface slightly convex, ventrally clearly convex (mainly at gular sutures); with dense umbilicate punctures on dorsal surface and sparse umbilicate punctures on ventral surface separated by more than 3x their width ( Fig. 22); temple without carinae, but with a narrow area slightly concave ( Fig. 29); eyes 0.33x as long as head, interocular distance 0.57x cephalic width; first antennomere 1.8x as long as antennomeres 2–3 combined, apical antennomere 0.92x as long as antennomeres 9–10 combined; labrum slightly bilobed ( Fig. 54); with mandibular external channel; apical maxillary palpomere conically elongate ( Fig. 39), twice as long as preapical palpomere; apical labial palpomere with apex slightly widened and flat ( Fig. 44), nearly twice as long as preapical palpomere.

Thorax. Pronotum 1.43x as long as wide; 1.08x cephalic width; with dense umbilicate punctures; with smooth longitudinal belt wider than in remaining species of this group, the narrowest portion 4–5x the width of an umbilicate puncture ( Fig. 50); without depressed areas in posterior third. Elytra as long as pronotum (0.97x); with less setae than on head, pronotum and abdomen. Prosternum transverse; with fine setae as dense as those on meso and metasternum.

Abdomen. Densely covered with brown setae, that is sparser and darker than in R. formicaria .

Aedeagus. Male unknown.

Variation. Unknown.

Comparison. Although the only specimen known is female, it has several unique characteristics to propose it as new species and to distinguish it from the remaining species of the “formicaria” species group: the oval and posteriorly narrowed head, the large eyes, the absence of carinae and presence of a slightly concave area on the temple of head, the smooth longitudinal belt that is wider than in other species of “formicaria” species group, and the small, longitudinal, carinate line on the prosternum.

Etymology. The species name is derived from the Latin words “glaber” and “notum”, and refers to the smooth longitudinal belt on the pronotum, which is wider than that of other species with dense umbilicate punctures on the head and pronotum.

Geographical distribution. Suriname.
