Duas novas espécies de Lopesia Rübsaamen (Diptera, Cecidomyiidae) do Brasil, com chave para as espécies

Abstract

Two new species of Lopesia Rübsaamen (Diptera, Cecidomyiidae) from Brazil, with an identification key of species. Biota Neotrop. 10(1): http://www.biotaneotropica.org.br/v10n1/ en/abstract?article+bn01510012010. Abstract: Lopesia erythroxyli Rodrigues & Maia and Lopesia maricaensisRodrigues & Maia, two new species of Cecidomyiidae that induce conical galls on bud of Erythroxylum ovalifolium Peyr (Erythroxylaceae) and on marginal leaf roll of Protium brasiliense (Spr.) Engl. (Burseraceae), are described and ilustrated (larva, pupa, male, and female) based on material from Rio de Janeiro, Brazil. A key to the known species of Lopesia is given.

Lopesia davillae (Diptera, Cecidomyiidae), a new species of gall midge from Brazil associated with Davilla rugosa (Dilleniaceae)

“…The first condition is found in 13 of the species of the genus, while the second condition is found in 11 species. The new species has setulose flagellomere necks as observed in L. brasiliensis Rübsaamen, 1908, L. caulinaris Maia, 2003, L. conspicua Maia, 2003, L. elliptica Maia, 2013, L. erythroxyli Rodrigues & Maia, 2010, L. linearis Maia, 2003, L. marginalis Maia, 2001, L. maricaensis Rodrigues & Maia, 2010, L. similis Maia, 2004, L. simplex Maia, 2002, and L. tibouchinae Maia, 2004 However, L. conspicua has four pairs of terminal papillae (larva) and a shorter prothoracic spiracle, while the new species presents only two pairs of terminal papillae and a longer prothoracic spiracle. In addition, L. tibouchinae has three-segmented palpi (adults), bifid antennal horns, and abdominal spines connected to one another (pupa), differing from the new species, in which the palpi are four-segmented, antennal horns are simple, and dorsal spines are not connected.…”

Three New Species of Lopesia Rübsaamen (Diptera: Cecidomyiidae) from Brazil

“…Running the key to segregation of Lopesia species (Rodrigues & Maia 2010), we observed that the specimens studied do not belong to any described species, although L. mataybae sp. nov. shares setulose flagellomere necks (couplet 1), narrow gonocoxites (couplet 2'), gynecoid male flagellomere (couplet 7), and wing with Rs joining R 1 after its midlength (couplet 8) with L. elliptica Maia, 2003(Madeira et al 2003; tarsal claws 1-toothed with (couplet 8') L. maricaensis Rodrigues & Maia, 2010 (Rodrigues & Maia 2010), and antennal horn of pupa developed (couplet 1), conspicuous apical setae of pupa, 0.05 mm long (couplets 2 and 3'), simple dorsal abdominal spines of pupa present, (couplets 4' and 6) with L. spinosa Maia, 2004. Despite the similarities, the following set of characteristics differentiates L. mataybae sp.…”

“…nov. shares with L. caulinaris Maia, and L. mataybae sp. nov. the setulose flagellomere necks (couplet 1), narrow gonocoxites (couplet 2'), and male flagellomere gynecoid (couplet 7); wing with Rs joining R 1 after its midlength (couplet 8) with L. elliptica Maia, 2003(Madeira et al 2003, tarsal claws 1-toothed with (couplet 8') with L. maricaensis Rodrigues & Maia, 2010(Rodrigues & Maia 2010; presence of larval prothoracic spatula with 2 teeth (couplets 1, 2', and 3), terminal segment of larva without reentrancy and terminal papillae equally long (couplets 4 and 5'), posterior margin of larval prothoracic spatula large and teeth of prothoracic spatula spaced apart, with lateral process and rounded at apex (couplets 7, 8', and 9) with L. linearis Maia, 2003. Despite those similarities, the following set of characteristics differentiates L. mataybae sp. nov. from its congeners: male cerci triangular and bilobed with rounded apex; aedeagus large and wide, larval terminal segment with 2 corniform papillae each side (as L. davillae Maia) and inducing galls on A. vermifuga.…”

New state record of Lopesia grandis Maia, 2001 (Insecta, Diptera, Cecidomyiidae)

“…Males, females, as well as larvae and pupae are important for identification. Rodrigues and Maia (2010) published an illustrated key to segregate the known species of Lopesia based on all described stages of the life cycle. Furthermore, the gall morphology is very useful to species identification, as it is unique to each galling species.…”
