Nothotrioza myrtoidis Burckhardt sp. n.

( Figs 2 B, E; 3A, B, D–F; 4A, D, E; 6; 7A–G)

Material examined. Holotype male, Brazil: Minas Gerais, Serra do Caraça (R. Carneiro) (MZSP, dry mounted). Paratypes. Brazil: 32 males, 30 females, 3 nymphs, same data as holotype (BMNH, ELEF, MHNG, MZSP, NHMB, dry and slide mounted, and in 70 % ethanol).

Description. Adult. Antennal segment 10 with longer terminal seta about 3 times as long as and shorter terminal seta slightly longer than segment 10. Forewing ( Fig. 2 B) with vein Rs strongly curved; cell cu1 relatively large and high, distance between apices of veins M3+4 and Cu1a around 0.6 times as long as that between apices of veins Cu1a and Cu1b, and distance between apices of vein Cu1a and Cu1b about 2.6 times as long as length of vein Cu1b; field of radular spinules in cell m2 distingly shorter than those in cells m1 and cu1. Male proctiger ( Fig. 3 D) with broadly rounded posterior margin, evenly narrowing from widest point towards the base. Paramere, in profile, with angular lobe slightly proximal from the middle at hind margin ( Fig. 3 E). Distal portion of aedeagus ( Fig. 3 F) with large apical hook. Female proctiger ( Fig. 4 A) with blunt tip apically. Fifth instar nymph ( Fig. 2 E): Caudal plate ( Fig. 4 E) with U-shaped hind margin. Measurements and ratios in Table 1.

Etymology. Named after its host species Psidium myrtoides .

Distribution. Brazil: Minas Gerais.

Host plant. Psidium myrtoides (Myrtaceae) .

Gall. Globoid, unilocular. Induced on the adaxial surface of the leaves, as the gall develops projecting towards the abaxial surface, assuming a globoid shape.
