description: Centistes grandis Almeida & Penteado-Dias sp. nov.
(Figs. 10A–E, 25A)
Diagnosis: Body length 4.1–5.6 mm; notauli present; vein (RS+M)a present and complete; precoxal sulcus present; scutellar sulcus scrobiculate; mesosoma black; hind coxa yellow; temple length 0.9–1.2× eye length in dorsal view; mesopleuron with anterobasal projection; and female with fore tarsus displaying a brush-like pubescence.
Comments: This species is similar to C. truncatus, especially due to the combination of a clearly defined notauli and the vein (RS+M)a being complete, fore tarsus displaying a brush-like pubescence, and having an overall similar body coloration. However, this species can be identified by having scutellar sulcus scrobiculate, larger eyes (temple length 0.9–1.2 × eye length in dorsal view) and all legs with coxa yellow.
Description. Female Body length: 5.1 (4.1–5.6) mm, mesosoma length 2.0 (1.5–2.2) mm. Head (Figs. 10A, C): Antenna with 32 (28–34) flagellomeres; occipital carina complete; scape cylindrical, pubescent; face setose and punctate, its minimum width 1.5 (1.4–1.6) × the clypeus width; face height 0.6 (0.6–0.7) × its maximum width; clypeus setose and punctate, its height 0.5 (0.5–0.6) × its width; gena setose and puncticulate; frons smooth, glabrous medially, with some setae laterally; vertex smooth with sparse setae; mandible overlap 0.5 (0.4–0.6) × mandible length; basal width of mandible 0.4 (0.4–0.5) × its length; malar space 0.4 (0.4–0.5) × eye height, and 1.7 (1.5–1.9) × basal width of mandible; eye height 1.6 (1.6–1.8) × its length; ocell-ocular distance 1.8 (1.6–1.8) × ocellar diameter; temple length 0.9 (0.9–1.2) × eye length in dorsal view. Mesosoma (Figs. 10B–D): Pronotum in lateral view smooth and mostly glabrous, with just a few setae on its borders; transverse sulcus of pronotum absent; mesonotal lobes smooth and mostly glabrous except median lobe setose anteriorly; pit on mesoscutum absent; notauli present; mesoscutum width 1.0 (1.0–1.2) × its length; scutellar sulcus scrobiculate; scutellum sparsely setose; posterior scutellar depression scrobiculate; mesopleuron punctate and setose with a smooth area medially; precoxal sulcus scrobiculate; metapleuron carinate-rugose, with projection present; propodeum truncate, rugose, without dorsal and ventral areolae, dorsal transverse carina present and complete. Legs (Fig. 10B): Fore leg with brush-like setae on the ventral side of tarsus I–IV; tarsal claw simple; hind coxa rugulose, setose. Wings (Fig. 25A) Vein (RS+M)a present and complete; stigma length 1.0 (1.0–1.1) × vein R1 length; vein r length 0.1 (0.1–0.2) × stigma length; vein CUa 0.4 (0.2–0.5) × vein CUb. Metasoma (Figs. 10D–E): T1 costate, without longitudinal carinae, its length 1.4 (1.2–1.8) × ovipositor sheath length; hypopygium rounded, sparsely setose; ovipositor sheath round and setose, apex roughly rounded, sheath length 2.0 (1.6–2.4) × its width. Coloration (Fig. 10B): Body mostly black except antenna dark brown, palpi and tegula yellow and legs yellow with tarsus brownish.
Male: Similar to females, except fore tarsus without brush-like pubescence; pronotum rugulose medially and on ventral margin; propodeum not truncated and rugose-areolate; body length 3.9–4.0 mm; mesosoma length 1.6– 1.7 mm; antenna with 27–28 flagellomeres; face minimum width 1.6–1.8 × clypeus width; clypeus height 0.6–0.7 × clypeus width; mandible overlap 0.6 × mandible length; basal width of mandible 0.5 × its length; malar space 1.5–1.6 × basal width of mandible; ocell-ocular distance 1.4–1.5 × ocellar diameter; stigma length 1.20 × vein R1 length.

Etymology: The specific epithet for this species is derived from the distinctively large body size in comparison to other known Brazilian species.
