Key to species of the genus Paranura
New species described here make it necessary to update the key that was provided by Palacios-Vargas and Simón Benito in 2008. Aside the new species described here, the new key includes among others species P. najtae Deharveng & Weiner, 1984 , P. clavisetis and P. s-uenoi Yosii, 1955 that were not considered by Palacios-Vargas and Simón Benito (2008). The first species, P. najtae (described from North Korea) was synonymised with P. ieti ( Yosii 1966) described from Nepal ( Cassagnau 1991). As differential characters between najtae and ieti are not discussed by Cassagnau (1991), the synonymy he proposes cannot be accepted at the moment. Our own observations suggest that the two species, though very similar morphologically, may be distinguished by the number of lateral chaetae and posterior tubercles on head. However, it should be noted that there are large differences between the different available descriptions of P. ieti ( Cassagnau 1991; Lee 1981; Yosii 1966, 1969) and undoubtedly the species needs revision based on type material or specimens from type locality. For the same reason, the synonymy between clavisetis and sexpunctata proposed by Massoud (1967) cannot be retained here, as the differential characters given in the original description ( Axelson, 1902) were not discussed when he placed the former species in synonymy of P. sexpunctata . Our key includes also P. s-uenoi that was considered by Palacios- Vargas and Simón Benito as a member of Nahuanura Palacios-Vargas & Najt, 1986, a genus characterized by the presence of reticulations on parts of the body ( Palacios-Vargas & Najt 1986). A detailed analysis of morphology of P. s-uenoi and related P. reticulata sp. nov. show that both species rather resembles the genus Oregonanura Smolis, 2008 ( Smolis 2008b) in having a unique very long abdominal segment V which is twice longer than the last one. In addition, the reticulation pattern of Nahuanura Palacios-Vargas & Najt, 1986 and the cited species are quite different, suggesting that it developed independantly (see remarks of P. reticulata sp. nov.). In comparison to both disputed species, Oreganura, however, has complete and strong developed tuberculation on the body. In the light of these facts we decided to classify P. s-uenoi and P. reticulata sp.nov. within Paranura . Regarding P. anops , it is not included in the key as it belongs to the genus Paleonura Cassagnau, 1982 of the tribe Paleonurini by its unpigmented eyes ( Palacios-Vargas & Simón Benito 2007b, Smolis & Kadej 2014). In addition, Paranura quadripunctata Yosii, 1966 from Nepal, considered as a species inquirenda by Cassagnau (1991), is not included in the key. Diagnostic characters of the central area of head are unknown in this species.
