Genus Antichiropus Attems, 1911

Antichiropus Attems 1911: 168 .

Type species. Antichiropus variabilis Attems, 1911 , by subsequent designation of Brölemann (1916).

Diagnosis. Car et al. (2013) suggested that the genus Antichiropus is most similar to the genus Notodesmus Chamberlin, 1920 and to several other undescribed genera that occur in Queensland and Victoria, but that Antichiropus may readily be distinguished by a unique combination of four gonopodal features. Firstly, the solenomere is remarkably long in Antichiropus : it is generally as long as the femorite and coiled into a complete circle, or more, in nearly all species. Secondly, all species of Antichiropus carry a large pointed process arising close to the femorite tip (known as the main femoral process). Thirdly, the sperm canal bends at a right angle at the tip of the femorite before extending into the solenomere. The fourth feature stated that Antichiropus species carry one process, namely the solenomere process 1 (sp1) in the apical third of the solenomere. There are, however, two species described below, A. julianneae Car , n. sp. and A. pendiculus Car , n. sp., from the Pilbara region of Western Australia that have proved to be the exceptions as they each lack this process, but the authors believe that these species conform to the generic definition in all other features and should be retained in Antichiropus .
