Centistes succinum Román & Sarmiento sp. nov.

(Figs. 21A–G, 24F)

Diagnosis: Centistes succinum differs from the other South American species by the following combination of characters: propodeum dorsally and posteriorly smooth, dorsally with an areola; vein (RS+M)a absent; ovipositor sheaths short and lanceolate; and body yellow except head and ovipositor sheaths dark brown.

Comments: Centistes succinum is similar to C. gasseni by sharing mostly yellow body coloration, which is not common in the genus, as well as the notauli being absent and a pit on the mesoscutum being present. However, they differ in the form of their propodeal areola and the ovipositor sheaths, as well as by the absence of vein (RS+M)a.

Description. Female. Body length: mesosoma length 1.84 mm. Head (Figs. 21B–C): antenna with 30 flagellomeres; face setose and smooth, minimum face width 1.2 × clypeus width; face length 0.8 × maximum face width; clypeus setose and smooth, clypeus length 0.5 × its width; gena sparsely setose and smooth; frons glabrous medially and smooth; vertex sparsely setose and smooth; mandibles when closed overlapping 0.4 × mandibles length, mandible width basally 0.4 × mandibles length; malar space length 0.1 × eye height in lateral view, and 0.6 × mandible width basally; eye height in lateral view 1.5 × eye length in dorsal view; lateral ocellus separated from compound eye 0.6 × ocellus diameter; temple length 0.6 × eye length in dorsal view. Mesosoma (Figs. 21D, G): pronotum sparsely setose, with transverse dorsal sulcus; pronotum in lateral view smooth, without carinae; median and lateral mesonotal lobes sparsely setose, smooth; pit on the mesoscutum absent; notauli absent; mesoscutum width 0.9 × 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 sparsely setose, metapleuron upper part scrobiculate and lower part smooth, supramesocoxal projection absent, with two carinae across the metapleuron; propodeum sparsely setose, not truncated, smooth, dorsal areola present, incomplete medial longitudinal carina, lateral longitudinal carina in dorsal view absent, transverse dorsal carina incomplete, propodeal areola present, hexagonal. Legs (Fig. 21A): coxa sparsely setose, tarsus I to IV of fore legs without brush-like pubescence; claws basal lobe absent. Wings (Fig. 24F): vein (RS+M)a absent, stigma length 0.7 × marginal cell length and × 0.8 vein R1 length, vein r length 0.2 × stigma length, vein 1CUa length 0.1 × vein 1CUb length. Metasoma (Figs. 21E–F): first tergite lineate, with median longitudinal carina incomplete, lateral longitudinal carina complete, smooth area basal, first tergite length 1.4 × ovipositor sheath length; hypopygium sparsely setose; ovipositor sheath setose, short, lanceolate, sheath tip dotted, thin plate on the edge absent, ovipositor sheath length 3.0 × its width. Coloration (Fig. 21A): head dark brown except clypeus, gena and mandible yellow; mesosoma yellow, coxa and femur yellow, tibia of leg I and II yellow, leg III mostly yellow except apex brown, tarsus of leg I and II yellow, tarsus of leg III brown; tegula yellow; wings hyaline, veins and stigma brown; metasoma yellow except ovipositor sheaths dark brown.

Male: Unknown.

Holotype female: COLOMBIA, Valle del Cauca, Parque Nacional Natural Farallones de Cali, Los Andes, Quebrada Honda N 3°34’ W 76°40’, 1730 m, Malaise, 16/ 17-ix-1998, H. Peña leg. (Deposited in IaVH, code: M.2286)

Etymology: The Latin word succinum, meaning amber, refers to the particular color of this species.
