Abstract Merodon natans group (Diptera, Syrphidae) taxa are reviewed using an integrative taxonomic approach combining morphological, morphometric and molecular techniques. The substantiates recognition of the three species: M. calcaratus (Fabricius, 1794), 1794) pulveris Vuji? & Radenkovi? in et al. 2011, reveals existence a new species, makrisi Vuji?, Tot sp. nov. , which is described...

The genus Curicaberis gen. nov. is described to include the type species, Curicaberis ferrugineus (C.L. Koch, 1836) comb. nov., and eight other species transferred from Olios Walckenaer, 1837: C. abnormis (Keyserling, 1884) comb. nov., C. annulatus (F.O. Pickard-Cambridge, 1900) comb. nov., C. bibranchiatus (Fox, 1937) comb. nov., C. ensiger (F.O. Pickard-Cambridge, 1900) comb. nov., C. ferrugi...

Caecilians (Lissamphibia: Gymnophiona) are unique among vertebrates in having two sets of jaw-closing muscles, one on either side of the jaw joint. Using data from high-resolution X-ray radiation computed tomography scans, we modelled the effect of these two muscle groups (mm. levatores mandibulae and m. interhyoideus posterior) on bite force over a range of gape angles, employing a simplified ...

The present study describes morphological and molecular detection of Rhipicephalus (Boophilus) microplus Haemaphysalis spp. Infesting cattle from different agro climatic zones Mizoram. Microscopy revealed hexagonal basis capitulum in both sexes, shorter mouth parts absence festoons on the posterior border. Morphologically, mouthparts showed laterally projected conical palps. They were without a...

Free-living stages of ticks on a commercial game farm in the Thabazimbi District, Limpopo Province, South Africa, were collected by drag-sampling with flannel strips during the period September 2003 to August 2004. A total of 5 tick species was collected from 4 sites. Boophilus decoloratus was the most abundant species, followed by Amblyomma hebraeum. Seasonal abundance of the ticks was quantif...

Southern cattle ticks, Boophilus microplus (Canestrini) (Acari: Ixodidae), collected in Coahuila, Mexico, were determined to be resistant to permethrin. Discriminating concentration (DC) tests at the LC99 and 2X the LC99 of susceptible ticks produced 0 and 0.5% mortality, respectively, for permethrin. However, measured mortalities for coumaphos and amitraz acaricides were within the expected ra...
