| scanning electron microscope study of a snake tick, amblyomma gervaisi (acari: ixodidae). | the scanning electron microscope (sem) studies on both male and female tick, amblyomma gervaisi (lucas 1847) inhabiting the snake naja naja were made. detail of the surface structures as seen under sem exhibit sexual dimorphism and were compared with other tick species as reported. sem observations show characteristic alloscutal ornamentation, inornate festoons, triangular licking organ, size of the hypostome, round haller's organ, genital plate oval in male and slit-like in female, and prominen ... | 2012 | 24082536 |
| comments on controversial tick (acari: ixodida) species names and species described or resurrected from 2003 to 2008. | there are numerous discrepancies in recent published lists of the ticks of the world. here we review the controversial names, presenting evidence for or against their validity and excluding some altogether. we also address spelling errors and present a list of 17 species described or resurrected during the years 2003-2008. we consider the following 35 tick species names to be invalid: argas fischeri audouin, 1826, ornithodoros boliviensis kohls and clifford, 1964, ornithodoros steini (schulze, 1 ... | 2009 | 19169832 |
| bothriocroton oudemansi (neumann, 1910) n. comb. (acari: ixodida: ixodidae), an ectoparasite of the western long-beaked echidna in papua new guinea: redescription of the male and first description of the female and nymph. | specimens of amblyomma oudemansi (neumann, 1910) were collected in papua new guinea from an endangered monotreme, zaglossus bruijni (peters & doria), the western long-beaked echidna. these ticks were compared morphologically and molecularly with species formerly assigned to aponomma neumann, 1899 (now included in bothriocroton keirans, king, & sharrad, 1994 or amblyomma koch, 1844), and a phylogeny was generated. based on our results, we reassign this tick to bothriocroton, as b. oudemansi (neum ... | 2008 | 18210218 |
| coendangered hard-ticks: threatened or threatening? | the overwhelming majority of animal conservation projects are focused on vertebrates, despite most of the species on earth being invertebrates. estimates state that about half of all named species of invertebrates are parasitic in at least one stage of their development. the dilemma of viewing parasites as biodiversity or pest has been discussed by several authors. however, ticks were omitted. the latest taxonomic synopses of non-fossil ixodidae consider valid 700 species. though, how many of th ... | 2011 | 21554736 |
| twentieth century occurrence of the long-beaked echidna zaglossus bruijnii in the kimberley region of australia. | the monotreme genus zaglossus, the largest egg-laying mammal, comprises several endangered taxa today known only from new guinea. zaglossus is considered to be extinct in australia, where its apparent occurrence (in addition to the large echidna genus megalibgwilia) is recorded by pleistocene fossil remains, as well as from convincing representations in aboriginal rock art from arnhem land (northern territory). here we report on the existence and history of a well documented but previously overl ... | 2012 | 23459668 |
