Centistes lobungula Román & Sarmiento sp. nov.

(Figs. 17A–G, 24D, 26E)

Diagnosis: This species differs from the others by the basal lobe of the claws (Fig. 26E) and the smooth first tergite.

Comments: The basal lobes in the claws of C. lobungula had not been reported in other species of the genus.

Mesosoma (Figs. 17D, G): pronotum glabrous, transverse dorsal sulcus absent; pronotum in lateral view sparsely setose, smooth, without carinae; median and lateral mesonotal lobes sparsely setose anteriorly, smooth; pit on the mesoscutum absent; notauli absent; mesoscutum width 1.1 × its length; scutellar sulcus with transverse carina; scutellum sparsely setose, smooth; posterior scutellar depression scrobiculate; mesopleuron setose with a glabrous area medially, smooth; precoxal sulcus absent; metapleuron setose, metapleuron upper part scrobiculate and lower part smooth, supramesocoxal projection present; propodeum glabrous, not truncated, dorsally and posteriorly smooth, dorsal areola absent, medial longitudinal carinae absent, lateral longitudinal carinae in dorsal view incomplete, transverse dorsal carinae absent; propodeal areolae present, hexagonal; Legs (Fig. 17A): tibia and tarsus highly setose; tarsus I to IV of fore legs without brush-like pubescence; claws basal lobe present. Wings (Fig. 24D): vein (RS+M)a absent, stigma length 0.7 × marginal cell length and equal to vein R1 length, vein r length 0.1 × stigma length, vein 1CUa length 0.07 (0.07–0.09) × vein 1CUb length. Metasoma (Figs. 17E–F): first tergite smooth, without longitudinal carinae, first tergite length 1.9 (1.9–2.0) × ovipositor sheath length; hypopygium setose; ovipositor sheath sparsely setose, short, oval, sheath tip round, thin plate on the edge absent, ovipositor sheath length 2.7 × its width. Coloration (Fig. 17A): Head dark brown except clypeus and mandible yellow; mesosoma dark brown except propleura yellow and brown; coxa yellow, femur of leg I and II yellow, leg III yellow with a brown base, tibia of leg I yellow, leg II brown, leg III dark brown, tarsus dark brown, tegula yellow; wing hyaline, veins and stigma yellow; metasoma dark brown and yellow except ovipositor sheaths dark brown.
