Gibertoni, Julia, Whitfield, James B. & Penteado-Dias, Angélica M., 2021, A new genus of Cedriini (Hymenoptera: Braconidae, Hormiinae) from the Brazilian cerrado, Zootaxa 5047 (4), pp. 489-494 : 490-492

Sagarana cerradensis n. sp.

( Figs 1‒10 )

Material examined: Holotype, 1 female ( DCBU320082 ), Brazil, Minas Gerais, Chapada Gaucha, 15 o 10’ 29.6”S / 45 o 43’ 18.5” O, 14 Aug. 2018, Malaise . Paratypes, 1 female ( DCBU320081 ) same collection locality as holotype, but 05 Jun. 2018 , 1 female ( DCBU320080 ) 19 Jun. 2018, 15 o 10’ 31.7”S / 45 o 43’ 14.9”O . N.W. Perioto & R.I. R. Lara Col .

Body length, 2.0 mm. Fore wing length, 1.9 mm

Head ( Figs 1- 4 ): Antennal sockets closer to eyes than to each other, antenna with 12 antennomeres, third antennomere longer than fourth. Malar suture absent. Occipital carina complete ( Fig. 1 ). Oral cavity small and transverse. Eyes with reduced pilosity.

Mesosoma: Mesoscutum covered with setae and with medial carina over posterior 0.75. Scutoscutellar sulcus represented by two large pits. Scutellum pentagonal. Propodeum with a large and longitudinally elongate roughly pentagonal areola divided by a carina near midlength into anterior and posterior regions ( Fig. 6 ).

Fore wing: 2nd submarginal cell open with absence of r-m vein; vein RS+M very disclosed from C+SC+ R by long 1RS ( Fig.8 ).

Legs: Slender, hind leg longer than metasoma with coxa shorter than first metasomal tergite. Meta tibial spurs small, 0.2 × hind basitarsus.

Metasoma: Petiole (tergite 1) with two dorsal and two lateral carinae, tergites carapace-like but hinged between 1 and 2. The second metasomal suture indistinct, second and third tergites being visibly separated only by the difference in the pattern of sculpture ( Fig.9 ). Hypopygium of medium size and densely setose. Ovipositor straight, of medium size, 4 × shorter than metasoma and evenly covered with setae. The ventral part of the second sternite is modified with paired deep depressions fringed by setae ( Fig. 10 ) and lined anterocentrally with small pits. The function of these structures is unknown.

Color: Yellowish brown, legs yellowish, antennomeres 1–6 pale yellow and 7–12 yellowish-brown, palpi pale yellowish, mesosoma brown, metasoma yellowish brown. Wings hyaline.

Male: Unknown.

Biology. Host unknown. All specimens were collected in the dry season.

Distribution. Cerrado of central Brazil (Chapada Gaucha, Minas Gerais, Brazil)
