Centistes soaresi Román & Almeida & Penteado-Dias & Shaw & Sarmiento 2025, sp. nov.

Centistes soaresi Almeida & Penteado-Dias sp. nov. (Figs. 20A–E, 25F) Diagnosis Vein (RS+M)a present and complete; mesonotal lobes smooth and mostly glabrous; pit on mesoscutum oval; notauli absent; propodeum without dorsal areola, ventral areola oblong; ovipositor sheath long, somewhat spatulate, with apex rounded and slightly enlarged; ovipositor sheath length 2.9–3.2 × its width; and ocell-ocular distance 1.4–1.6 × ocellar diameter. Comments: Centistes soaresi is similar to C. puntarenensis Aguirre, Almeida, & Shaw, both share a complete vein (RS+M)a, pit on mesoscutum present, and similar ocelli. The new species can be distinguished by its distinctive ovipositor sheath, having the apex rounded and slightly enlarged. Description.

Head (Figs. 20B–C): Antenna with 21 (21–22) flagellomeres; occipital carina complete, scape cylindrical; face setose and punctate, its minimum width 1.5 (1.4–1.6) × clypeus width; face height 0.8 (0.7–0.8) × its maximum width; clypeus smooth with some sparse and long setae; clypeus height 0.6 (0.5–0.6) × clypeus width; gena smooth with a few scattered setae; frons smooth and polished; vertex smooth with just a few setae; mandible overlap 0.6 × mandible length; basal width of mandible 0.4 (0.3–0.4) × its length; malar space 0.3 (0.3–0.4) × eye height, malar space 1.4 (1.4–1.5) × basal width of mandible; eye height 1.5 (1.4–1.6) × its length; ocell-ocular distance 1.4 (1.4–1.6) × ocellar diameter; temple length 1.1 (1.0–1.2) × eye length in dorsal view. Mesosoma (Figs. 20C–D): Pronotum in lateral view slightly rugulose, and mostly glabrous, with just a few setae on borders; transverse sulcus of pronotum absent; pronotum carina subparallel and horizontal; mesonotal lobes smooth and mostly glabrous except median lobe setose anteriorly; pit on mesoscutum oval; notauli absent; mesoscutum width 1.2 (1.1–1.2) × its length; scutellar sulcus with a transverse carina; scutellum sparsely setose; mesopleuron smooth, slightly setose with a glabrous area medially; precoxal sulcus rugose; metapleuron carinate-rugose with dorsomedial area smooth; projection of metapleuron absent; propodeum with medial longitudinal carina incomplete, lateral longitudinal carinae and dorsal areola absent; ventral areola oblong, dorsal transverse carina complete; propodeum sparsely setose, smooth dorsally, rugose posteriorly. Legs (Fig. 20A): Tarsal claw simple; hind coxa costate, setose. Wings (Fig. 25F): Vein (RS+M)a present and complete, stigma length 1.3 (1.1–1.3) × vein R1 length; vein r length 0.1 × stigma length; vein CUa 0.3 (0.3–0.4) × vein CUb. Metasoma (Figs. 20D–E): T1 costate, without longitudinal carinae; T1 length 1.0 (1.0–1.2) × ovipositor sheath length; ovipositor sheath with a normal border, weakly spatulate, with apex rounded and slightly enlarged, sheath length 3.1 (2.9–3.2) × its width; hypopygium rounded and glabrous. Coloration (Fig. 20A): Body dark brown, except clypeus (and sometimes base of gena), base of antenna and legs yellow. Male: Unknown. Examined Material: Holotype female: Itamonte, MG, Brazil, Serra da Mantiqueira (RPPN-APA-UCF), S 22° 22’ 25” W 44° 48’ 41”, Malaise 9, 2149 m, 10.xii.2015, A.S. Soares e L.A.M. Soares cols., DCBU 274616. Paratypes: 2 females: DCBU 274620, DCBU274621, same data as holotype. Etymology: The specific epithet is a patronym given in recognition of Airton Santos Soares, who collected the holotype of this species.
