Cave Pseudosinella and Oncopodura New to Science

Table 1. New and Undescribed Species of Cave Pseudosinella. In connection with our updating of The Collembola of North America we have uncovered a considerable number of undescribed species of cave Collembola. Some of these, of the genera Arrhopalites, Oncopodura, and Pseudosinella, are so striking and clear cut that we feel it best to describe and name them before producing part II of the update. In this paper we describe nine new species of the genera Pseudosinella and Oncopodura. In a subsequent paper we shall describe the members of the genus Arrhopalites. The species described herein and the regions they are found in are given to the right. First we describe several species of the genus Pseudosinella, which has been the subject of many studies in this country and elsewhere and whose phylogeny and classification are reasonably well understood (Christiansen, da Gama & Bellinger, 1983; da Gama, 1984). We take this opportunity to describe those for which satisfactory material is available, and to give tabular summary of these as well as other species that cannot be described at present because adequate material is not available (see Table 1). Data on these species will be entered into the BUGS DELTA program available through Grinnell College, which may be used to identify species of the genus (Christiansen, Bellinger & da Gama, 1990). Table 2 gives the character states of the new species fitting the different features discussed in the above paper.
