“…In D. gigantea Angelo & Maia, the gonostylus is setose dorsally on its basal third (Angelo and Maia 1999), as in the two species from Leptospermum, whereas in D. marginalis Maia it is setose almost to its tip (Maia et al 2005). Differences are also found in the shape of the aedeagus, which is narrow and rounded apically in D. gigantea and D. marginalis Maia but truncated and notched in D. myrciariae Maia (Maia 1995). Good differences are found in the shape of the pupal antennal bases, which are barely developed in D. strobila, bear tiny pointed projections in D. myrciariae, D. tavaresi Maia (Maia 1995) and D. tomentosa, developed into small tapered horns in D. globosa Maia and D. marginalis (Maia 1995;Maia et al 2005), or form flat, slightly bi-lobed ridges in D. gigantea (Angelo and Maia 1999).…”

Two new species of gall midges, Dasineura strobila Dorchin n.sp. and D. tomentosa Dorchin n.sp., are described from galls in vegetative and reproductive buds of coastal tea tree, Leptospermum laevigatum from Australia and South Africa. Galls cause abortion of buds and, when induced in reproductive tissues, prevent fruit set and seed formation. Despite their assumed relatedness, the two species exhibit clear morphological differences in larvae, pupae and adults of both sexes as well as in the morphology of their galls. These are the first Dasineura species to be described from plants of the Myrtaceae outside the Neotropical and Nearctic regions and the first ones recorded from the chiefly Australian subfamily Leptospermoideae. Given the effect of galls on growth and reproduction of the plant, the gall midges are considered as possible biological control agents of coastal tea tree in areas of Australia and South Africa where the plant is an invasive weed.

“…In the Rio Grande do Sul State, there are five reported species of this genus (Marchiori & Sobral 1997). Three Cecidomyiidae species have been recorded as galls inducer on this plant genus: Dasineura myrciariae Maia 1996, Myrciariamyia bivalva Maia 1995and Myrciariamyia fernandesi Maia 2004; the first two species are associated with leaves of Myrciaria floribunda (H. West ex Willd.) O. Berg and the other species induce bud galls on Myrciaria tenella (DC.)…”

By not having any of the sets of features above, Fernandesia cannot be placed to tribe. Lasiopteridi comprise 59 genera which are also unplaced to tribe, being 21 Neotropical (Gagné 2010). An identification key of tribes Lasiopteridi and a key to segregate the Neotropical genera are provided, as well, to better characterize the new genus. All specimens were first preserved in 96% alcohol and later mounted on slides following the methodology of Gagné (1994). The material (including the types) was incorporated in the Diptera collection of Museu Nacional, Rio de Janeiro, Brazil. The terminology of the adult and immature stages follows Gagné (2009). Material and Methods SamplesField work and gall midge rearing were done by C. R. Wenzel and M. S. Mendonça, Jr. and the descriptions of the new taxa were done by A. R. Rodrigues and V. C. Maia.The key of Lasiopteridi tribes was based on diagnoses of Gagné (2010). The key of unplaced genera of Neotropical Lasiopteridi were done based on original descriptions (Brethes 1917, Felt 1922, Kieffer 1913a, b, Kieffer & Herbst 1909, 1911, Kieffer & Jörgensen 1910, Gagné 1994, Maia 1994, 1995b, 2001, 2005, Rübsaamen 1905, 1916, Tavares 1909) is presented, excepting Angeomyia Kieffer & Herbst 1909, known only from the larva. Results and DiscussionFernandesia Rodrigues & Maia, gen. nov. Diagnosis. Adult: male circumfila irregular, made up of many short loops; palpi four-segmented; wing: R 5 straight and shorter than wing, Sc and Rs absent, M3 present, Cu forked; tarsal claws one-toothed curved after midlength, empodia longer than bend in claws; male terminalia: cercus, hypoproct and aedeagus shorter than gonocoxites, hypoproct bilobed, mediobasal gonocoxite lobes well-developed; ovipositor barely protrusible, female cerci fused. Pupa: antennal base only slightly modified into a right angle at its anteromesal corner; prothoracic spiracle elongated; abdominal segments without dorsal spines; terminal segment bilobed. Larva: prothoracic spatula with two apical teeth; two groups of three and two lateral papillae; terminal segment bilobed, full complement of terminal papillae, with four corniform papillae on each lobe.Description: Adult. Head: males with 24+? flagellomeres (antennae broken) and females with 28-29 flagellomeres, flagellomeres 1 and 2 connected, male circumfila wavy, male flagellomere necks striated; palpus four-segmented. Thorax: R 1 reaching C before wing midlength, R 5 straight reaching C before apex, Sc and Rs absent, Cu forked, M3 present; tarsal claws one-toothed, curved after midlength, empodia longer than bend in claws. Abdomen: male tergite 8 not sclerotized, male sternites 2-8 sclerotized, female tergites 1-8 sclerotized, female sternite 8 slightly sclerotized; male cercus ovoid, hypoproct bilobed, aedeagus shorter than gonocoxites, mediobasal

“…Although much is known about the ecology of some of the species of Cecidomyiidae, mainly from Europe and United States, the number of species (and even of genera) described in this family is still growing remarkably around the world, for example in Western Europe (e.g. Fedotova, 1994Fedotova, , 1993aFedotova, , 1993b, Brazil (Maia, 1995a(Maia, , 1995b(Maia, , 1993a(Maia, , 1993bMaia & Couri, 1993;Maia et al, 1996) and USA (Gagné & Bennett, 1993;Gagné & Strong, 1993). These works are essentially of taxonomic nature, and much more is needed to understand the ecology and evolution of this group as a whole.…”

The development of the galls of the midge Eugeniamyia dispar Maia, Mendonça-Jr. & Romanowski, 1996 (Diptera: Cecidomyiidae) was monitored weekly on its host plant, Eugenia uniflora (Myrtaceae). The work was carried out in the urban area of Porto Alegre, RS, Brazil, from October 1993 to September 1995. Galls were collected from the field and raised in the laboratory to obtain adults. The females oviposit on young leaves of the host plant, with the first instar larvae inducing the gall, which is unilocular. The last instar larvae drop to the soil to pupate and later emerge as adults. The galls occur from late August to early June, when young leaves of the host can be found, with populations peaking during the summer. So far this species is only known from the two southernmost states of Brazil (RS and SC).
