Diagnosis. This new species could be distinguished from the remaining species of Allorhogas from Brazil by having the following combination of features: 1) mesosoma brown to dark brown; 2) first and second metasomal tergites costate, smooth between carinae, remaining tergites smooth and polished (first and second tergites costate but with coriaceous sculpture between carinae and third tergite also sculptured in other Brazilian species with dark brown colour). Description. Female. Body size 2.7 mm (Fig. 3A ), forewing 2.4 mm. Colour : head brown, temple, gena and clypeus light brown; palpi pale yellow; scape and pedicel yellow; basal flagellomeres brown, turning black to apex; eyes dark brown to black; mesosoma dark brown, lower part of mesopleuron brown; metasoma brown to dark brown; legs pale yellow; tarsal claws black; wings hyaline, forewing veins brown to light brown, stigma brown; hindwing veins pale yellow; ovipositor sheaths dark brown to black, ovipositor brown, apex strongly sclerotised.

( A, C-F female, holotype B female, paratype) A habitus, lateral, view B mesosoma, lateral view C head, dorsal view D mesosoma, dorsal view E metasoma, dorsal view F wings. Head : transverse in dorsal view, 1.5 times wider than its median length (dorsal view) (Fig. 3C ), 0.6 times as long as high (lateral view); occipital carina complete and reaching hypostomal carina before mandible; post ocellar line (POL) as long than ocellar diameter (OD), 0.5 times ocular ocellar line (OOL); frons, vertex, temple, gena and clypeus coriaceous; face sparsely pilose, coriaceous, transversally rugose laterobasally (Fig. 2B ), with a smooth median area; area surrounding clypeus and gena with large pilosity; clypeus coriaceous; frons excavation distinct but not defined by sharp lateral margins; eye 1.3 times longer than wide; eye width 2.0 times longer than temple in dorsal view; malar space 0.3 times eye height and 1.7 longer than width of hypoclypeal depression; mandibles tridentate, teeth short and relatively equal in size; antenna with 26 flagellomeres, first flagellomere about 3.6 times longer than wide, 1.3 times longer than second one. Mesosoma : 1.6 times longer than high (Fig. 3B ) and 1.6 times longer than wide (Fig. 3D ); pronotal collar short but visible in dorsal view, pronotal furrow scrobiculate-coriaceous; mesoscutum transverse in dorsal view, its median length 0.7 times its width; mesoscutal lobes coriaceous, median lobe with an indistinct median longitudinally rugose stripe, notauli scrobiculate, not meeting, reaching the end of scutellum in a longitudinally rugose area; scutellar disc coriaceous, prescutellar furrow with five transverse carinae; mesopleuron coriaceous, anterior part slightly transversally costate; subalar groove wide, scrobiculate; precoxal sulcus wide deep, coriaceous and slightly scrobiculate, running along two thirds of mesopleuron; metapleuron coriaceous-slightly rugose medially, scrobiculate along edges; propodeum basally coriaceous, with two distinct diverging carinae, rugose laterally and apically in areolar area. Wings : forewing 2.7 times longer than wide (Fig. 3F ). Pterostigma 2.8 times as long as wide and 0.7 times as long as R. Vein r 0.9 times as long as 3RSa, 0.2 times as long as 3RSb, and as long as r-m. Vein 2RS interstitial with m-cu, vein RS+Mb absent. Hindwing vein M + CU 0.7 times as long as 1 M, m-cu slightly curved towards wing apex. Legs : hind coxa with a distinct basoventral tooth. Hind femur 3.2 times longer than wide. Metasoma : first tergite 1.3 times wider than long, longitudinally costate, smooth between carinae; with two subparallel longitudinal carinae running to apex, anteriorly delimited by an indistinct transverse carina (Fig. 3E ). Second tergite longitudinally costate, smooth between carinae; line between second and third tergites distinct and straight; remaining tergites smooth and polished. Ovipositor sheaths 1.1 times longer than metasoma. Variation. Body size 2.7-2.9 mm. Head and mesosoma brown to dark brown. Antenna with 25-26 flagellomeres. Male. Similar to female. Body size 2.6-2.7 mm. Antenna with 28 flagellomeres. Hind femur swollen, 2.6 times longer than wide. Holotype. Female (DCBU 420470).

(DCBU 420459, 420471; IBUNAM). One male, three females, same data as holotype. Biology. The type specimens of this species were reared from fruits of Ilex affinis Gardner ( Aquifoliaceae ). Etymology. The name of this species refers to the host plant species where the type specimens were reared.
