Hybotinae (Diptera, Empidoidea, Hybotidae) from the Dominican Republic: new records and description of new species

Hybotinae is being recorded for the first time to Dominican Republic where the subfamily becomes represented by the genera Euhybus Coquillett, 1895, Neohybos Ale-Rocha & Carvalho, 2003 and Syneches Walker, 1852. Euhybus and Neohybos occur exclusively in the Americas, and Syneches is cosmopolitan. Six new species are described and illustrated: Euhybus martiniensis sp. nov., Neohybos cinereus sp. nov., N. longicornis sp. nov., N. pruinosus sp. nov., N. setosus sp. nov. and Syneches dominicanus sp. nov.. Identification keys are provided for the species of the three hybotine genera registered in West Indies. The following species are recorded for the first time from the Dominican Republic: Syneches inversus Curran, 1928, S. pallidus Wilder, 1974 and S. vineus Wilder, 1974. The previously unknown female of S. inversus is described.

Comparative description of the immature stages of two very similar leaf footed bugs, Holymenia clavigera (Herbst) and Anisoscelis foliacea marginella (Dallas) (Hemiptera, Coreidae, Anisoscelini)

Holymenia clavigera (Herbst, 1784) and Anisoscelis foliacea marginella (Dallas, 1852) (Hemiptera, Coreidae) present a remarkable similarity regarding egg and nymphal morphology. On the contrary, their adult stages are remarkably different. This study describes and compares the immature stages of these two coreid species. Excepting for the last instar and the shape of the hind tibia from third to last instar, nymphs of both species were identical in their gross morphologies and ultrastructures. However, H. clavigera was significantly larger than A. foliacea marginella in all stages. Thus, we suggest that these species may have evolved through evolutionary convergence, parsimony between the immature stages after speciation, Müllerian mimicry or genetic drift.

Taxonomy and morphology of Apsil Malloch (Diptera, Muscidae, Coenosiinae, Coenosiini) with new records, description of a new species and a key to identification

Taxonomy and morphology of Apsil Malloch (Diptera, Muscidae, Coenosiinae, Coenosiini) with new records, description of a new species and a key to identification. Apsil Malloch (Diptera, Muscidae, Coenosiinae, Coenosiini) includes 10 species, most of them described from Chile, but some also from Argentina. Five of them and one new species were found at the California Academy of Sciences collection (San Francisco, California) during the course of a project developed in that institution. Almost all material studied was collected in Chile, mainly by M. E. Irwin, during the year of 1966. Brief diagnosis of the known studied species (A. apicata Malloch, A. atripes Malloch, A. dilata Malloch, A. maculiventris Malloch (female described for the first time) and A. spatulata, Malloch), the description of A. mallochi, sp. nov. and a key for the identification of all known species are given. Color illustrations of some morphological characters make easier the recognition of the species. New geographic records were assigned.

Influence of male nutritional conditions on the performance and alimentary selection of wild females of Anastrepha obliqua (Macquart)(Diptera, Tephritidae)

Influence of male nutritional conditions on the performance and alimentary selection of wild females of Anastrepha obliqua (Macquart) (Diptera, Tephritidae). The behavior of A. obliqua females is regulated by endogenous and exogenous factors and among these the presence of males. Experiments were carried out to investigate whether the presence of males and their nutritional condition may affect the behavior of self-selection feeding and the performance of A. obliqua females. Females were sorted in groups containing yeast-deprived females and males, and non-yeast-deprived females and males. The females were maintained apart from the males by a transparent plastic screen. Several yeast and sucrose combinations were offered to the females in a single diet block or in separate blocks. Ingestion, egg production, longevity and diet efficiency were determined. The non-yeast-deprived males positively influenced the females performance when the latter were fed with yeast and sucrose in distinct diet blocks. Performance was better in the groups without males and with yeast-deprived males where the females could not select the nutrient proportions (yeast and sucrose in a single diet block).

Description of Photuris fulvipes (Blanchard) immatures (Coleoptera, Lampyridae, Photurinae) and bionomic aspects under laboratory conditions

Larvae and pupae of the cryptic firefly Photuris fulvipes (Blanchard,1837) are described. They were reared to adult stage from eggs laid by a female collected in São Luiz do Paraitinga, São Paulo, Brazil. Additionally, adult diagnosis and some bionomic data observed in the laboratory are presented. The bionomical and morphological characteristics of P. fulvipes were compared to other unidentified species of the genus and to Bycellonycha sp. from literature. At moment, the data are insufficient to propose a diagnosis for the species, but some characteristics appear to define species group or, at least, they may have generic value.

The presence of Chane Nieto and Guajirolus Flowers (Ephemeroptera, Baetidae) in Brazil with the description of a new species

The related genera Chane and Guajirolus are reported for the first time from Brazil. Guajirolus rondoni, sp. n. is described based on nymphs from Rondônia State and can be differentiated from the other species of the genus by the following combination of characteristics: 1) mandibles with minute spicules on outer margin; 2) maxillary palp three-segmented; 3) hypopharynx lingua with three rounded processes; 4) projection of second segment of labial palp with apex narrower than base; 5) abdominal color pattern; and 6) paraprocts with 13 to 15 organized spines. An updated key to the species of both genera is presented.
