Two new species of Riethia Kieffer, 1917, R. chilensis sp. nov. (Chile) and ecuadoriensis (Ecuador) are described figured as adult males. The two differ from the presumable closest relative, truncatocaudata (Edwards, 1931), by uniformly coloured legs, without bands, stout curved hypopygial superior volsellae; they can be separated all other shape setation pattern inferior volsella. each in body colouration, including abdomen, presence/absence microtrichia on volsellae.
Abstract The evolutionary consequences of phenotypic plasticity are debated. For example, reproductive barriers between incipient species can depend on the social environment, but most evidence for this comes from studies focusing effects experiencing heterospecific individuals opposite sex. In Drosophila melanogaster, males well known to invest strategically in ejaculate components and show different courtship behavior when reared presence male competitors. It is unknown whether such...
Poxyaibamberus Andersen & Dantas, gen. nov. is erected based on the males of two species, P. jamanximensis sp. from Jamanxim National Park, Pará State, Brazil, and ubajarensis Ubajara Ceará Brazil. Both species have a comparatively short wide head, with large eyes short, five-segmented palps; strong subapical seta ultimate flagellomere; scalpellate acrostichals; no setae wing veins except for one brachiolum; long costal extension; triangular anal point very heel gonostylus. The...
Petalocladius dominiensis Andersen & Baranov sp. n. is described and figured based on an adult male collected in the Ebano Verde Scientific Reserve Dominican Republic. The new species can be separated from its only congener, P. setosus Sublette Wirth, 1972 Jamaica, as it slightly smaller with about 115 dorsocentrals compared to 56 setosus. inferior volsella broadly subtriangular, while more lingulate setosus, gonostylus has a small, but distinct megaseta subapical brush of spine-like...
Chironomus fumeus Walley in Curran, 1934 was described based on a single male from British Guyana. When reviewing the type specimens of Chironomidae (Diptera) American Museum Natural History, Sublette erected monotypic genus Psilochironomus Sublette, 1966 species. Subsequently, Sæther included when he suggested new tribe Pseudochironomini Sæther, 1977. However, specimen’s hypopygium has been missing since before Sublette’s examination; thus, Spies & Reiss 1996 considered both C. and to...
Sympatric distribution and syntopy are not common in closely related species since sporadic crosses may lead to the formation of hybrid zones disrupting differentiation sympatric incipient species. In Central Spain two morphologically similar Mediimorda Méquignon, 1946, M. batteni Plaza-Infante, 1985 bipunctata (Germar, 1827) strictly sympatric. is endemic Iberian Peninsula while widely distributed Western Palaearctic Region. Intriguingly, among taxa that exhibits little morphological...
The cytochrome c oxidase subunit I (COI) gene has been used broadly as a DNA barcoding region or and relevant molecular marker for phylogenetic reconstruction. exact that standardized universal barcode is the one amplified by Folmer's primers HCO-LCO. Nevertheless, many other have developed amplification of COI gene, among them Jerry-Pat primers. This paper aims to analyze performance different regions COI, in particular those primers, on taxonomic levels using specimens from complex...
