Centistes iguaquensis Román & Sarmiento sp. nov.

( Figs. 14A–G , 24E )

Diagnosis: C. iguaquensis differs from the others by the following combination of characters: propodeum dorsally and posteriorly costate, with areola present and pentagonal; vein (RS+M)a absent; and ovipositor sheaths large, oval and with thin plate on the edge.

Comments: Centistes iguaquensis and C. truncatus share characters such as having the propodeum costate and dark body coloration; however, C. iguaquensis has the propodeal areola and vein (RS+M)a absent.

Description. Female. Body length: mesosoma length 1.35 (1.35–1.43) mm. Head ( Figs. 14B–C ): antenna with 28 flagellomeres; face setose and smooth, minimum face width 1.2 × clypeus width; face length 0.5 × maximum face width; clypeus setose and smooth, clypeus length 0.5 × its width; gena setose and smooth; frons smooth; vertex sparsely setose and smooth; mandibles when closed overlapping 0.5 × mandibles length, mandible width basally 0.4 × mandibles length; malar space length 0.5 × eye height in lateral view, and 1.6 × mandible width basally; eye height in lateral view 1.7 (1.5–1.7) × eye length in dorsal view; lateral ocellus separated from compound eye 2.5 (2.2–2.5) × ocellus diameter; temple length 1.2 × eye length in dorsal view. Mesosoma ( Figs. 14D, G ): pronotum sparsely setose, with transverse dorsal sulcus; pronotum in lateral view smooth, without carinae; median and lateral mesonotal lobes setose anteriorly, smooth; pit on the mesoscutum absent; notauli present; mesoscutum width 1.1 × its length; scutellar sulcus scrobiculate; scutellum sparsely setose, smooth; posterior scutellar depression scrobiculate; mesopleuron setose with a glabrous area medially, smooth; precoxal sulcus present, scrobiculate; metapleuron sparsely setose, metapleuron upper part scrobiculate and lower part rugulose, supramesocoxal projection absent; propodeum sparsely setose, not truncated, costate, dorsal areolae absent, dorsal longitudinal carinae absent, transverse dorsal carina absent, propodeal areola present, hexagonal. Legs ( Fig. 14A ): coxa sparsely setose, tarsus I to IV of fore legs without brush-like pubescence; claws basal lobe absent. Wings ( Fig. 24E ): vein (RS+M)a absent, stigma length 0.6 × marginal cell length and × 0.8 vein R1 length, vein r length 0.2 × stigma length, vein 1CUa length 0.4 × vein 1CUb length. Metasoma ( Figs. 14E–F ): first tergite lineate, without longitudinal carinae, smooth area absent, first tergite length 0.9 (0.9–1.0) × ovipositor sheath length; hypopygium sparsely setose; ovipositor sheath sparsely setose, large, oval, sheath tip round, thin plate on the edge present, ovipositor sheath length 2.5 (2.5–2.8) × its width. Coloration ( Fig. 14A ): Head black except scape dark brown and mandible yellow with brown tips; mesosoma black, coxa black and dark brown, femur dark brown, tibia and tarsus brown; tegula dark brown; wings hyaline, vein and stigma yellow; metasoma black and dark brown.
