Terminalia ( Fig. 4f ): gonocoxite cylindrical setose, about 3.1 times length of gonostylus; gonostylus ovoid setose with some long setae, gonostylus teeth triangular, in lateral view; cerci wide setose, lobes ovoid divergent, with setae only apically; hypoproct setose slightly bilobed, with a pair of setae apically, slightly longer than cercus; aedeagus triangular narrow pointed at apex, almost as long as hypoproct.

Female abdomen ( Fig. 4g ): 1 st – 7 th tergites rectangular with a posterior row of setae, lateral row of setae, one pair of trichoid sensilla. 8 th tergite with scattered setulae. 1 st – 6 th sternites rectangular with a posterior row of setae, lateral row of setae, some mesal setae, one pair of trichoid sensilla, and elsewhere covered with setulae. 7 th sternite rectangular with apex rounded, about 2.2 times length of preceding sternite, rectangular, more sclerotized at distal margin, with scattered setae and two basal trichoid sensilla. 8 th sternite unsclerotized.Ovipositor: base tubular, rigid portion with 3.1 times length of 7 th sternite.

Pupa. Body length: 2.31 – 2.73 mm (n = 6). Cephalic region ( Fig. 5a ): antennal horns concave laterally, with micro-serrated margin, 0.11 – 0.18 mm of length (n = 6); cephalic setae 0.075 – 0.085 mm of length (n = 6); two pairs of lower lateral papillae (one setose and the other bare); three pairs of lateral papillae (two setose and one bare); upper facial margin thickened laterally; apical plate integument smooth ( Fig. 5b ). Prothoracic spiracle cylindrical and elongated, slightly curved, 0.17 – 0.23 mm of length (n= 6) ( Figs. 5a and b ). Prothoracic integument grainy as in the Fig. 5b . 3 rd – 9 th abdominal segments with numerous dorsal spines ( Fig. 5c ). Abdominal spiracles conical on 4 th – 7 th segments, length of abdominal spiracle 5: 0.03 – 0.05 mm (n= 6). Terminal segment bilobed in males ( Fig. 5d ) and rounded with a slightly reentrance in females, with dorsal spines.

Larva. white, body cylindrical, rounded anteriorly and tapered to end, length: 1.52 mm (n = 1), integument grainy. Prothoracic spatula length: 0.20 mm (n = 1), width: 0.07 mm (n = 1); four-toothed, internal teeth slightly longer than the external one; surrounding area pigmented; three setose lateral papillae at each side ( Fig. 5e ). Terminal segment rounded without visible papillae.

Material examined. Holotype: Male, BRAZIL, Rio de Janeiro, Mangaratiba city, Ilha da Marambaia, Armação beach , 21.xi.2010, Rodrigues, A. R. col.. Paratypes: same locality, data and collector: 2 females, 1 pupa, 5 pupal exuvia, and 1 larva .

Gall. on fruits of Ocotea notata ( Lauraceae ), ovoid, yellow-green, glabrous, one-chambered, with a single larva inside, pupation in the gall ( Fig. 1b ). Fruit with gall similar to healthy fruit. Occurrence from October to December of 2010.

Etymology. The specific name is the genitive of the host plant species.

Remarks. Bruggmanniella . notatae sp. nov. and B. persae Gagné, 2004 are unique among the other congeneric species in having larva with sclerotized area around the prothoracic spatula, but the former differs by having prothoracic spatula with all teeth acute and pupal antennal horns strongly concave laterally, while the latter has the prothoracic spatula with mesal teeth less acute than the lateral and pupal antennal horns strongly concave laterally.
