Anisodiplosis waltheriae Maia, sp. nov. (Figs. 1–19)

Adult. Body length: 3.0– 3.2 mm in male (n = 5); 4.25–4.95 mm in female (n = 5).

Head (Figs. 1, 2): eye facets circular, closely appressed. Antenna with scape obconic, pedicel globose, male flagellomeres: basal and distal circumfila with loops subequal in length, middle circumfilum with loops shorter and having fewer connections to flagellomere (Fig.3); female flagellomeres each with 2 connected ring­circumfila (Fig. 4); flagellomere necks bare in both sexes, male necks longer than in female, 12th flagellomere elongate and narrow apically in both sexes (shorter in female). Flagellomeres 1 and 2 not connate. Frontoclypeus with 4–8 setae. Labrum long­attenuate with 3 pairs of ventral sensory setae. Hypopharynx of same shape as labrum, with long, anteriorly directed lateral setulae. Labella elongate­convex, each with several lateral setae and 2 or 3 pairs of short mesal sensory setae. Palpus with three setose segments: segment one spheroid, segment 2 cylindrical and 3 claviform.

Thorax: Anepimeron setose, other pleural sclerites asetose. Wing (Fig. 5) length: 2.10–2.25 mm in male (n = 7); 3.05–3.15 mm in female (n = 5). Tarsal claws bowed at midlength, simple; empodium rudimentary (Fig. 6).

Abdomen. Male (Fig. 7): tergites 1–6 rectangular with complete row of caudal setae, several lateral setae, 2 basal trichoid sensilla, and elsewhere with scattered scales. Tergite 7 laterally tapered with setae more abundant mesally and apically and 1 basal pair of trichoid sensilla. Tergite 8 narrower than the preceding, with basal and distal margins irregularly sclerotized, tapered laterally, with 2 trichoid sensilla. Sternites 2–7 rectangular with setae more abundant mesally, 1 complete row of caudal setae and 2 basal trichoid sensilla. Sternite 8 ovoid with several scattered setae and 2 basal trichoid sensilla. Female (Fig. 8): tergites 1–6 as for male. Tergite 7 rectangular with 1 complete row of caudal setae, several lateral setae, 2 basal trichoid sensilla, and elsewhere with scattered scales; tergite 8 with irregular margins and 2 basal trichoid sensilla. Sternites 2–7 similar to those of male. Sternite 8 not sclerotized. Male terminalia (Fig. 9): gonocoxites wide, not splayed, with short mesobasal rounded lobes; gonostylus robust; cercus oval, setose; hypoproct simple or slightly bilobed, much longer than cerci, as long as aedeagus (slightly shorter or slightly longer in some specimens); parameres absent; aedeagus tapering gradually to rounded apex.

Ovipositor protrusible, tapering to apex, striate and setose; cerci elongate­ovoid, separate, setose (Figs. 10–11).

Pupa. Color: brownish. Length: 4.4–4.9 mm (n = 5). Cephalic region (Fig. 12): antennal horn as marginal thickening; cephalic seta short, 0.02–0.03 mm in length (n = 5); frontal horns absent; 2 pairs of frontal papillae (1 pair setose and other without seta); 3 pairs of lateral facial papillae (1 pair setose and other asetose). Upper cephalic margin thickened laterally. Thorax: prothoracic spiracle elongate, attenuate to apex and well developed, 0.21–0.31 mm in length (n = 5) (Fig. 13). Wing sheath reaching distal margin of abdominal segment 3; foreleg sheath reaching distal margin of abdominal segment 4; midleg sheath ending immediately beyond basal margin of abdominal segment 5; hindleg sheath reaching basal ¼ of abdominal segment 5. Abdomen: segments 2–8 with single row of conspicuous dorsal spines; segment 2 with 6–9 spines; segment 3, 7–9; segment 4, 7–8; segments 5 and 6, 5–7; segment 7, 4–6; segment 8, 4–9; and segment 9 without spines (Fig. 14).

Larva. Body elongate, cylindrical, tapered at both ends, widest at thorax (Fig.15). Length: 1.85–3.2 mm (n = 10). Integument rough. Spatula length: 0.12–0.16 mm, spatula with 2 well­developed apical teeth and reduced stalk (Fig. 16). Two groups of 3 lateral papillae per side (2 of each group setose, 1 asetose) (Fig. 16). Terminal segment convex, with 3 pairs of setose terminal papillae (Fig. 17).

Gall. Spherical to conical, with short, light yellow trichomes, one­chambered, on leaves, leaf buds, and inflorescences. Longest axis of galls averaging 3.7 0.6 mm (n = 89) (Figs. 18, 19).

Type material. Holotype male. BRAZIL, Minas Gerais: Aimorés, VII.2004, J. W. Fernandes leg., MNRJ. Paratypes: same data as holotype 6 males, 5 females, 6 pupal exuviae, 4 pupae, 13 larvae.

Etymology. The species name waltheriae is the genitive of the host­plant generic name.
