Haromyia, a new genus of long-legged flies from Dominica (Diptera: Dolichopodidae).
The new micro-dolichopodid genus Haromyia gen. nov. and the type species H. iviei sp. nov. are described from the island of Dominica in the Lesser Antilles. Males and females of Haromyia are distinguished by the large setae on a bulging clypeus, minute size, and wing veins that are nearly straight and evenly diverging from wing base. Haromyia does not fit readily into any contemporary dolichopo...
متن کاملJumping from the surface of water by the long-legged fly Hydrophorus (Diptera, Dolichopodidae).
The fly Hydrophorus alboflorens (4 mm long, 4.7 mg mass) moves around upon and jumps from water without its tarsi penetrating the surface. All six tarsi have a surface area of 1.3 mm(-2) in contact with the water, but they did not dimple its surface when standing. Jumping was propelled by depression of the trochantera of both hind and middle legs, which are 40% longer than the front legs and 17...
متن کاملSpecies-specific genitalic copulatory courtship in sepsid flies (Diptera, Sepsidae, Microsepsis) and theories of genitalic evolution.
Males of Microsepsis eberhardi and M. armillata use their genitalic surstyli to rhythmically squeeze the female's abdomen with stereotyped movements during copulation. Squeezing movements did not begin until intromission had occurred and, contrary to predictions of the conflict-of-interest hypothesis for genitalic evolution, did not overcome morphological or behavioral female resistance. Contra...
متن کاملA second update to the checklist of Finnish long-legged flies (Diptera: Dolichopodidae), with a re-evaluation of the status of Hydrophorus callosoma Frey, 1915
Eighteen species of long-legged flies (Dolichopodidae) are reported as new to Finland. A further species, Microphorellapraecox (Loew), is confirmed as a Finnish species. The status of Hydrophoruscallosoma Frey, 1915 is re-evaluated and a lectotype is designated for the species. Hydrophorusalbosignatus Ringdahl, 1919 is found to be a junior synonym of Hydrophoruscallosoma (syn. n.). Characters f...
