Description. Adult. Body length (antenna not included): 3.2 – 3.8 mm in male (n=6); 2.9 – 4.0 mm in female (n=14). Head ( Fig. 1A View Figure 1 ): Eyes dark brown, holoptic, facets hexagonal, closely adjacent; occipital prominence absent. Frons with 20-25 setae. Labellum hemispherical with 8-9 scales in the proximal region and 5-6 setae in the distal region. Male antenna with 34 barrel-shaped and stalked flagellomeres; all with basal whorl of long setae, 2-3 hooded pores, and two trichoid sensillae in medial to distal region of the flagellomere, circumfila appressed, with two whorls connected by a small ring at the lateral surface ( Fig. 1B View Figure 1 ); female antennae with 43 flagellomeres, barrel-shaped, stalk smaller than in male ( Fig. 1C View Figure 1 ), circumfila as in male; in both sexes: first and second flagellomeres not fused; all flagellomeres with same length, except for the two first and the two last, more elongated than the other; apical process present in the last segment, and last flagellomere fused with the preceding one ( Figs. 1D and 1E View Figure 1 ). Palpus 2-segmented, cylindrical, first and second fused, with the first + second palpomeres slightly shorter than third; strong setae along palpomeres as in Fig. 1F View Figure 1 . Thorax: Legs: densely covered with scales; tarsal claws bent before midlength, toothed; empodia as long as tarsal claws ( Fig. 1G View Figure 1 ). Wings: hyaline with scales on veins ( Fig. 2A View Figure 2 ); length 3.0 – 4.0 mm in males (n=06) and females (N=14).
Male abdomen: First through 6 th tergites, weakly sclerotized, an anterior pair of trichoid sensilla, a row of strong posterior setae, and sparse, scattered scales over all the tergites, lateral setae absent; 7 th tergite narrower with a double row of posterior setae and an anterior pair of trichoid sensilla; 8 th tergite not sclerotized, indicated by a double row of posterior setae, trichoid sensilla absent; pleura thickly covered with scales; 2 nd through 7 th sternites rectangular weakly sclerotized, with a row of posterior setae, medioanterior pair of trichoid sensilla, sclerotized regions with completely covered by scales and setae; 8 th sternite quadrate, completely covered by scales and setae; trichoid sensilla absent ( Fig. 2C View Figure 2 ). Terminalia ( Fig. 3A View Figure 3 ): cerci bilobed, each lobe round at tip, with 6-7 prominent caudal setae; hypoproct lobes triangular, lobes divided about ½ of their length, each lobe tapering to the pointed apex, apical setae absent; aedeagus slender, cylindrical, and distinctly longer than hypoproct; gonocoxite oblong, with a conspicuous apicoventral lobe and a large mediobasal lobe semicircular, lobes divided at base, and completely covered with microtrichia; gonocoxite setae mainly on distal part of dorsal surface and scattered over lateral and ventral surfaces; gonostylus clavate with a curved, stout, one pointed apical tooth. Setation as in Fig. 3A View Figure 3 .
Female abdomen: Tergites and sclerites as for male, except for 8 th sclerite quadrate, weakly sclerotized with an anterior pair of trichoid sensilla and a row of posterior setae (see Fig. 3E View Figure 3 ). Ovipositor ( Fig. 3D View Figure 3 ): telescoped, protrusible portion of ovipositor, including cerci, about 2.0 times longer than 8 th sternite, with microtrichia in dense transverse rows; cercus fused, setae scattered sparsely apically; hypoproct short, cylindrical, with microtrichia densely distributed.
Pupa. Body length 3.2 – 3.6 mm, maximum width 1.4 – 1.8 mm (N = 05). Integument color: eyes, wing and anterior portion of legs sheaths black, other parts of body light brown in both males and females. Antennal bases and frons without projections (apical setae, lower and lateral facial papillae absent) ( Fig. 4A View Figure 4 ); prothoracic spiracles short (0,08- 0,09 mm), N=05), rounded apically ( Fig.4B View Figure 4 ); a pair of abdominal spiracles sclerotized attached internally to trachea on segments 4-7 ( Fig. 4C View Figure 4 ); tergites and sternites covered by micro spines ( Fig. 4C View Figure 4 ).
Larva (third instar). Body oval, creamy-white. Body length 2.1 – 2.4 mm, maximum width 0.9 – 1.1 mm (N = 10). Spatula transverse, bilobed, each lobe acute, stalk absent ( Fig. 4D View Figure 4 ); lateral papillae not apparent; spiracles conspicuous with sclerotized outgrows in all segments of abdomen; terminal segment round without terminal papillae.
Gall and Biology ( Fig. 4E View Figure 4 ). Male and female galls are sessile, cream-colored, pocket-like swellings inside the Ficus citrifolia syconia ( Moraceae ). It grows from the fig wall tissues towards the fig cavity, occupying most of its volume by the end of the fig development. On the external fig surface, it is possible to notice lumps or protuberances that indicate the presence of developing galls. The galls in which the female of the type species, F. perarticulata , develops are longer and stalked, while that of the male are shorter and sessile. The galls in which male and female develop are sessile and indistinguishable from each other in new species. Differently to the fig wasps, the gall midge adult emerges towards the fig exterior and the pupal exuvia remains protruding through the emergency holes. In the Ribeirão Preto population, F. brasiliensis is parasitized by species of Physothorax Mayr, 1885 ( Torymidae : Chalcidoidea) and Sycophila Walker, 1871 ( Eurytomidae : Chalcidoidea) wasps (Barros, personal communication).

Holotype – Male [permanent slide] (deposited in MZSP); Brazil: São Paulo, Ribeirão Preto (21°10’S; 47°48’W) collected from May to June 2019, emerged on June 14, 2019, on syconia of Ficus citrifolia Mill. ( Moraceae ), Barros, L.O. col. Paratypes. Same data of holotype, 01 male, 02 females, 05 pupae and 03 larvae [in permanent slides] (deposited in MZSP).Additional material: Same data, 04 males, 12 females, 05 pupae, and 03 larvae [in ethanol 70%].
Etymology. The specific name “brasiliensis ” means that the insect is from Brazil.
