Four New Mouse Spider Species (Araneae, Mygalomorphae, Actinopodidae, Missulena) From Western Australia, Laura T. Miglio, Danilo Harms, Volker W. Framenau, Mark S. Harvey
Research outputs 2014 to 2021
Four new species of the Mouse Spider genus Missulena Walckenaer, 1805 (family Actinopodidae) are described from Western Australia based on morphological features of adult males. Missulena leniae sp. n. (from the Carnarvon and Yalgoo biogeographic regions), Missulena mainae sp. n. (Carnarvon), Missulena melissae sp. n. (Pilbara) and Missulena pinguipes sp. n. (Mallee) represent a broad spectrum of morphological diversity found in this genus and differ from other congeners by details of the male copulatory bulb, colour patterns, eye sizes, leg morphology and leg spination. Two of the species, M. pinguipes sp. n. and M. mainae sp. n., are characterised by …
A Review And Redescription Of The Cosmopolitan Pseudoscorpion Chelifer Cancroides (Pseudoscorpiones: Cheliferidae), Mark S. Harvey
A Review And Redescription Of The Cosmopolitan Pseudoscorpion Chelifer Cancroides (Pseudoscorpiones: Cheliferidae), Mark S. Harvey
Research outputs 2014 to 2021
The taxonomy of the cheliferid pseudoscorpion genus Chelifer Geoffroy 1762 is reviewed with a single cosmopolitan species, Chelifer cancroides (Linnaeus 1758), with the subspecies C. cancroides orientalis Morikawa 1954 from Japan newly synonymised with C. cancroides. Adults and the final two nymphal stages (tritonymph and deutonymph) are redescribed based on numerous specimens from Europe, North America, Asia and Australasia. The large size variation evident in the samples is documented. The latero-ventral process of the tarsal claws characteristically found in adults (except leg I of the male) is lacking in nymphs, a pattern that is also confirmed in the genera Lissochelifer …
Identification Of Unknowns Within A Probabilistic System: The Diagnostic Value Of Attributes, D W. Goodall
Identification Of Unknowns Within A Probabilistic System: The Diagnostic Value Of Attributes, D W. Goodall
Research outputs 2014 to 2021
Using a data base underpinned by probability considerations in which a variety of attributes, some of which may be quantitative, are recorded for a number of “operational taxonomic units” (OTUs), a key system is described by which an unnamed specimen may quickly be identified. The concept of “diagnostic power” is introduced, by which each attribute is evaluated in terms of its potential contribution to identifying the unnamed specimen. Besides coverage of different types of attributes and the introduction of “diagnostic power”, the system has the advantages of incorporating multiple values of an attribute for each OTU and offering short-cuts to …
A New Troglobitic Ideoroncid Pseudoscorpion (Pseudoscorpiones: Ideoroncidae) From Southern Africa, Mark S. Harvey, Gerhard Du Preez
A New Troglobitic Ideoroncid Pseudoscorpion (Pseudoscorpiones: Ideoroncidae) From Southern Africa, Mark S. Harvey, Gerhard Du Preez
Research outputs 2014 to 2021
The first blind African species of Ideoroncidae is described from a cave in northwestern Botswana, Botswanoncus ellisi, representing a new genus and a new species. Apart from the complete lack of eyes, it is also unusual in having the lowest recorded number of trichobothria of any adult ideoroncid with 17 on the fixed finger and nine on the movable finger.
