Paralobella palustris sp nov (Collembola: Neanuridae: Neanurinae) from China, with remarks and key to species of the genus

The genus Paralobella is reported from mainland China for the first time by a new species, Paralobella palustris, described here. Paralobella palustris sp. nov. differs from all known members of the genus in the specific character of 20 teeth on mandible, 4 teeth and 2 hooks on maxilla, 5 chaetae (4+s) on each tubercle L of Abd. II-III, 8 chaetae (7+s) on tubercle L of Abd. IV. The new species is assigned to Paralobella because most characters comply with the diagnosis of the genus given by Cassagnau and Deharveng (1984). It is proposed that the generic diagnosis is slightly modified to take into account some additional characters, such as mandible with many teeth (more than 3 main), the tubercle De on Abd. V separated from tubercle Dl and tubercle Oc with 1 or 2 chaetae. The above mentioned characters broaden the previous diagnosis. This diagnosis allows for including 7 species, i.e., Lobella (Lobella) apsala Yosii, 1976, L.(Lobella) erawan Yosii, 1976, L.(Lobellina) paraperfusa (Gapud, 1968), L. (Lobellina) penangensis Yosii, 1976, L.(Lobellina) sabahna Yoshii, 1981 and L.(Lobellina) selangorica Yosii, 1976 and L. (Propeanura) kinabaluensis Yoshii, 1981 into the genus Paralobella.
