Lopesia brasiliensis Rübsaamen, 1908 was described as male, female and larva, based on material from the States of Rio de Janeiro and Santa Catarina (Brazil). This cecidomyiid induces leaf galls on Ossaea sp. (Melastomataceae). The pupa is described and illustrated for the first time.

Key words: Gall; Melastomataceae; morphology; Ossaea; taxonomy.

Lopesia was described by RÜBSAAMEN (1908) to a single species – L. brasiliensis, based on larva and adults of both sexes. The type material was collected in the State of Rio de Janeiro and Santa Catarina (Brazil). In this paper, the pupa of L. brasiliensis is described and illustrated for the first time based on material from the Reserva Biológica da União (Casimiro de Abreu, Rio de Janeiro).



The studied material comprises five pupal exuviae and a single pupa and was donated by Ricardo Ferreira Monteiro (Universidade Federal do Rio de Janeiro, Departamento de Ecologia). The pupa and pupal exuviae were prepared and mounted on slides, following the methods described in GAGNÉ (1994).

Pupa. Length: 3.9-4.6 mm (n = 3). Head (Fig. 1): antennal horn bifid, well developed and with 0.06-0.08 mm of length; two pairs of vertical papillae, one nonsetose and one with a short seta (length: 0.02-0.03 mm) (Fig. 2); two pairs of lower facial papillae (one setose and one nonsetose; Fig. 3); three pairs of lateral facial papillae (one setose and two nonsetose, Fig. 4); upper cephalic margin laterally thickened. Thorax: prothoracic spiracle sclerotized, setiform and long (length: 0.45-0.53 mm, Fig. 5). Abdome: segments 1-8 with dorsal spines (Figs 6 and 7), varying in number (Tab. I); segments 2-6 with proeminent spiracles; terminal segment with two conspicuous apical lobes (Fig. 7).
