Centistes rosae

description: Centistes rosae Román & Sarmiento sp. nov.
(Figs. 18A–G, 24B)
Diagnosis: This species differs from the others by the following combination of characters: pit on the mesoscutum present, precoxal sulcus absent, vein (RS+M)a present as a short stub.
Comments: Centistes rosae is similar to C. auricephalus and C. hirsutus in having the pit on the mesoscutum and similar head pubescence. However, Centistes rosae differs by the coloration of the head and the precoxal sulcus absent. It is also similar to C. pilosus but C. rosae has the vein (RS+M) as a short stub. We describe this species from one individual, because the analyses place it as an independent entity from C. auricephalus. Likewise, the shape of the wings, the head, and the discrete characters show clear differences with respect to C. auricephalus and other species such as C. pilosus and C. hirsutus.
Description. Female. Body length: mesosoma length 1.20 mm. Head (Figs. 18A–C): antenna with 22 flagellomeres; face setose and smooth, minimum face width equal to clypeus width; face length 0.9 × maximum face width; clypeus setose and smooth, clypeus length 0.4 × its width; gena setose and smooth; frons upper middle part glabrous and smooth; vertex setose and smooth; mandibles when closed overlapping 0.3 × mandibles length, mandible width basally 0.4 × mandibles length; malar space length 0.2 × eye height in lateral view, and 0.8 × mandible width basally; eye height in lateral view 1.3 × eye length in dorsal view; lateral ocellus separated from compound eye 1.3 × ocellus diameter; temple length 0.8 × eye length in dorsal view. Mesosoma (Figs. 18D, G): pronotum sparsely setose, with transverse dorsal sulcus, pronotum in lateral view smooth, without carinae; median and lateral mesonotal lobes setose; pit on the mesoscutum present; notauli absent; mesoscutum width 1.1 × its length; scutellar sulcus sparsely setose, with transverse carina; scutellum setose, smooth; posterior scutellar depression scrobiculate; mesopleuron setose; precoxal sulcus absent; metapleuron setose, upper part scrobiculate and lower part smooth; supramesocoxal projection absent; propodeum setose, not truncated, dorsal and posteriorly smooth, dorsal areola absent, complete medial longitudinal carina in dorsal view without ramification, lateral longitudinal carina in dorsal view incomplete, transverse dorsal carina absent; propodeal areola present, hexagonal. Legs (Fig. 18A): tarsus I to IV of fore legs without brush-like pubescence; claws basal lobe absent. Wings (Fig. 24B): vein (RS+M)a present, like a short stub; stigma length 0.7 × marginal cell length and 1.1 × vein R1 length, vein r length 0.2 × stigma length, vein 1CUa length 0.3 × vein 1CUb length. Metasoma (Figs. 18E–F): first tergite lineate, without longitudinal carinae, basal area smooth; first tergite length 1.2 × ovipositor sheath length; hypopygium sparsely setae; ovipositor sheath sparsely setae, short, oblong, sheath tip rounded, thin plates of the edges absent, ovipositor sheath length 3.4 × its width. Coloration (Fig. 18A): head dark brown except for clypeus, gena and mandible yellow; mesosoma black-dark brown except for pronotum 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 dark brown; tegula dark brown; wings hyaline, veins and stigma brown; metasoma black and dark brown.
