Diagnosis. This new species could be distinguished from the remaining described species of Allorhogas by having the following combination of morphological features: 1) body greenish pale yellow (never greenish pale yellow in the remaining species); 2) claws white (dark in the remaining species); 3) anterior half of notauli strongly scrobiculate and distinct, posterior half less sculptured and distinct, not meeting, reaching the end of scutellum in a smooth-rugose area with two subparallel longitudinal carinae (notauli usually entirely distinct, without such longitudinal carinae in the remaining species); 4) vein 2RS distal with m-cu, vein RS+Mb absent (variable in the remaining species). Description. Female. Body size 2.9 mm (Fig. 7A ), forewing 2.4 mm. Colour : body greenish honey yellow, scutellar area surrounding scutellar disc brown; eyes silver; scape, pedicel and flagellomeres pale yellow; palpi white; precoxal sulcus honey yellow; legs whitish yellow, claws white; wings hyaline, fore and hindwing veins and pterostigma pale yellow; ovipositor sheaths pale yellow, turning dark brown to apex, ovipositor pale yellow, apex strongly sclerotised.

( A-E female, holotype F female, paratype) A habitus, lateral, view; B head and mesosoma, lateral view C wings D head, dorsal view E metasoma, dorsal view F mesosoma, dorsal view. Head : transverse in dorsal view, 1.7 times wider than its median length (dorsal view) (Fig. 7D ), 1.1 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, slightly rugulose medially (Fig. 2F ); frons excavation slightly distinct, not defined by sharp lateral margins; eye 1.2 times longer than wide; eye width 3.0 times longer than temple in dorsal view; malar space 0.4 times eye height and 1.4 longer than width of hypoclypeal depression; mandibles bidentate; antenna with 22 flagellomeres, first flagellomere about 4.3 times longer than wide, 1.2 times longer than second one. Mesosoma : 1.7 times longer than high (Fig. 7B ) and 1.5 times longer than wide (Fig. 7F ); pronotal collar short but visible in dorsal view, pronotal furrow wide, deep and scrobiculate; mesoscutum transverse in dorsal view, its median length 0.8 times its width; mesoscutal lobes coriaceous; median lobe with an indistinct median longitudinal elevated stripe; notauli wide, deep and scrobiculate on basal half, narrowing and obscuring towards apical half, not meeting, reaching the end of scutellum in a rugose area; scutellar disc coriaceous; prescutellar furrow with five transverse carinae; mesopleuron coriaceous, transversally rugose antero-basally; subalar groove wide and rugose-scrobiculate; precoxal sulcus wide, deep and coriaceous, running along 0.6 of mesopleuron; metapleuron coriaceous-rugose medially, rugose-areolate along edges; propodeum basally coriaceous, with two distinct diverging carinae, rugose-areolate and slightly coriaceous apically and apically in areolar area. Wings : forewing 3.0 times longer than wide (Fig. 7C ). Pterostigma 2.4 times as long as wide and 0.6 times as long as R. Vein r 0.4 times as long as 3RSa, 0.1 times as long as 3RSb, and 0.8 times as long as r-m. Vein 2RS distal 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 coriaceous, striate ventrally with distinct, pointed basoventral tooth. Hind femur 3.2 times longer than wide. Metasoma : first tergite 0.9 times as wide as long, longitudinally costate, with two indistinct longitudinal subparallel carinae, with a basal transverse carina (Fig. 7E ). Second and basal two thirds of third tergite longitudinally costate, line between second and third tergites distinct and slightly sinuate, apical third of third and remaining tergites smooth and polished. Ovipositor sheaths as long as metasoma. Variation. Body size 2.5-2.9 mm. Prescutellar furrow with 4-5 transverse carinae. Male. Similar to female. Body slightly darker in one specimen. Body size 2.8-2.9 mm. Antenna with 22-23 flagellomeres. Hind femur swollen, 2.2-2.6 times longer than wide. Holotype. Female (DCBU 420460). Brazil, Rio de Janeiro, Barra de Marica , Restinga; 17.VII.1997; V. Maia col.; ex. galhas conicas de Stephomyia rotundifoliorum em Eugenia rotundifolia . Paratypes. (DCBU 420461-65; IBUNAM). 4 females, 3 males, same data as holotype; 12.XII.1997. Biology. The type specimens of A. viridis were reared from conical galls apparently made by an undetermined cecidomyiid dipteran on leaves of Eugenia rotundifolia Casar. ( Myrtaceae ). These galls are cylindrical, unilocular, externally brown and internally white ( Maia 1993 ). Etymology. The epithet of this species derives from the Latin word viridi (green), in reference to its distinctive greenish colour.
