description: Centistes itatiaiaensis Almeida & Penteado-Dias sp. nov.
(Figs. 16A–E, 25C)
Diagnosis: Vein (RS+M)a present as a short stub; pit on mesoscutum absent; notauli absent; precoxal sulcus absent; propodeum with large smooth areas anterodorsally and inside ventral areola; ovipositor sheath length 2.7–3.5 × its width; face and stigma black.
Comments: Centistes itatiaiaensis is similar to C. rosae, C. auristigma and C. auricephalus as all species share a vein (RS+M)a present as a short stub. Centistes itatiaiaensis and C. rosae can be distinguished from the others by the absence of the precoxal sulcus. C. itatiaiaensis can be distinguished from C. rosae by the absence of the pit on the mesoscutum and the dark brown gena.
Description. Female Body length: 3.42 (3.42–3.61) mm; mesosoma length 1.45 (1.45–1.49) mm. Head (Figs. 16B–C): Antenna with 26 flagellomeres; occipital carina complete; scape cylindrical; face setose and punctate, its minimum width 1.4 (1.4–1.5) × clypeus width; face height 0.6 (0.6–0.7) × its maximum width; clypeus setose and punctate; clypeus height 0.6 × its width; gena smooth and setose; frons smooth and polished; vertex smooth with just a few setae; mandible overlap 0.7 × mandible length; basal width of mandible 0.6 (0.5–0.6) × its length; malar space 0.3 × eye height; malar space 1.0 (1.0–1.2) × basal width of mandible; eye height 1.5 (1.5–1.5) × its length; ocell-ocular distance 1.5 (1.4–1.5) × ocellar diameter; temple length 1.0 × eye length in dorsal view. Mesosoma (Figs. 16C–D): Pronotum in lateral view mostly smooth, rugulose antero-ventrally and mostly glabrous, with just a few setae on borders; transverse sulcus of pronotum absent; pit on mesoscutum absent; notauli absent; mesonotal lobes smooth and mostly glabrous except median lobe setose anteriorly; mesoscutum width 1.0 × its length; scutellar sulcus scrobiculate; scutellum sparsely setose; mesopleuron smooth and mostly glabrous, with sparse setae on its borders; precoxal sulcus absent; projection of metapleuron absent; propodeum not truncated, dorsal areola poorly defined, ventral areola hexagonal, lateral longitudinal carinae absent, medial longitudinal carina incomplete; propodeum with large smooth areas anterodorsally and inside ventral areola. Legs (Fig. 16A): Tarsal claw simple; hind coxa costate, setose. Wings (Fig. 25C): Vein (RS+M)a present as a short stub; stigma length 0.99 × vein R1 length; vein r length 0.1 × stigma length; vein CUa 0.3 (0.1–0.3) × vein CUb. Metasoma (Figs. 16D–E): T1 costate, with medial longitudinal carina complete (lateral longitudinal carinae also complete); T1 length 1.4 (1.3–1.5) × ovipositor sheath length; ovipositor sheath long, with a thin border, and weakly lanceolate; hypopygium rounded, sparsely setose; sheath length 3.5 (2.7–3.5) × its width. Coloration (Fig. 16A): Body mostly black, with ventral margin of clypeus brownish, scape and pedicel honey yellow, propleuron, pronotum and metasoma ventrally yellow; legs yellow except hind leg with tarsus and apical half of tibia dark brown.
