Note on R. kistarae Røen, 1973 View in CoL

As R. latens shows closest affinities to the poorly known R. kistarae View in CoL until the detailed limb features of both species can be examined, the general features of the Greenland species are shown again here, after the original description by Røen (1973) ( Fig 5 View FIGURE 5 ). Sinev & Kotov (2014) consider this a valid species, which we agree with. In general habitus and size, R. kistarae View in CoL resembles R. latens strongly ( Fig. 5A View FIGURE 5 ), with a similar rostrum, curved inwards ( Fig. 5 View FIGURE 5 A–B) yet the posterior marginal setae on the carapace are not as long in R. kistarae View in CoL ( Figs 5A, C View FIGURE 5 ). The labral keel ( Fig. 5D View FIGURE 5 ) is similar in shape in both taxa, yet the marginal teeth on the postabdomen ( Figs 5 View FIGURE 5 F–G) are different. In R. kistarae, Røen (1973) View in CoL mentions that there are only two or three large teeth here with a gap ( Fig. 5F View FIGURE 5 ), as opposed to five to six in a continuous row in R. latens . Also the head pore arrangement is different based on the drawings of Røen (1973): in R. kistarae View in CoL , the lateral (small) pores are adjacent and more posterior relative to the major pore ( Fig. 5E View FIGURE 5 ), as in the majority of Rhynchotalona View in CoL species. However, we would like to note that strong care should be taken here until R. kistarae View in CoL is revised in detail on material from Greenland, in particular to understand the variability of the postabdomen and to confirm the head pore arrangement. Molecular methods would help in the future to clarify Rhynchotalona View in CoL systematics, including Røen’s peculiar taxon from Greenland.
