Pseudospurs are absent on t 1 and t 2 of mid and hind legs. Mid and hind femur with keel. Pulvilli well-developed, almost half as long as the claws. Lengths and proportions of legs in Table 2.</p><p>Hypopygium. As in Fig. 3b. Laterosternite IX with 6–7 setae (L = 25 µm). Phallapodme (59–66) 64 μm long; sternapodeme (90–105) 99 μm long. Anal point mostly hyaline, triangular with 13–19 setae, (56–89) 67 µm long. Superior volsella (Fig. 3b–c) with caudomedian projections long, finger-like, curved evenly before meeting medially, L = 84 µm. Inferior volsella simple triangular, lobe with blunt tip and slightly dilated at apex, L = 19 µm. Gonocoxite 278 µm long. Gonostyle curved with slight bent distally (Fig. 3b), L = 171 µm. Crista dorsalis long and low, megaseta L = 17 µm. HR = 1.6, HV = 1.8.</p><p>Remarks. This species is closely related to the Rheocricotopus (Rheocricotopus) reduncus . Combination of lower AR, lower BR, higher number of setae on AnP, longer AnP, a more evenly curved caudomedian projection of SVo (Figs 3b–c; compared to mainly bent in R. reduncus Fig. 4a–b), apically dilated IVo, broad horizontal sternapodeme (Fig. 3b; compared to narrow arched in R. reduncus, Fig. 4c), lower HR and HV separates the two species.</p><p>Based on the form of SVo this species belongs to the effusus group. Given the similarity of R. reduncus, R. reduncuiodes with other species within the effusus group a re-evaluation of the distinguishing characters is required to separate the species. In the effusus group the anal point length and thoracic chaetotaxy characters may not be sufficient to separate the species in this group. Saether and Schnell (1988) provided a somewhat better alternative for separating species in this group by listing the main comparative characters in a table. Following their example, we modified and corrected some of these characters and added few more (Table 3).</p><p>A notable change to the characters given by Saether and Schnell (1988) is the AR range of R. reduncus . The Norwegian specimens of R. reduncus described by Saether and Schnell (1988) have AR 0.83–0.90 while Makarchenko and Makarchenko (2005) described the species from Far Eastern Russia with AR range of 1.16–1.17. This somewhat changes the state of characters given by Saether (1985) and discussed by Saether and Schnell (1988). If we are to consider Makarchenko and Makarchenko (2005) description of R. reduncus then the trend 8 of Saether’s (1985) classification of the genus, describing a male AR of 0.6–0.8, does not longer hold for this species. Consequently, the characteristic of AR should no longer be considered apomorphic for R. reduncus . For 1 st of trend 7 in Saether’s (1985) both R. reducncus and R. reduncusoides are synapomorphous (digitiform caudomedian projection) and symplesiomorphous for second (with small humeral pit). The broad horizontal sternapodeme of R. reduncusoides is autapomorphic for this species.</p></div>	https://treatment.plazi.org/id/03CB87EF4C55697E9193FA8CFDF7F9A0	Public Domain	No known copyright restrictions apply.

Costal extension ~ 30 μm............................. R. (R.) eminellobus Saether ‡</p><p>10b. Gc with inner proximal margin continuing straight where it meets the IVo which ends in a small posteriorly directed lobe. (Saether 1985, fig.15C; Caldwell 1984, fig. 2). Costal extension 15–30 μm............. R. (R.) tuberculatus Caldwell ‡</p><p>*Will also key to R. reduncus Saether and Schnell, a Palearctic species. See diagnosis and remarks under R. reduncusoides, and Table 3 to separate the two species.</p><p>†Theses three species in the effusus group are difficult to separate. See Table 3 for combination of characters, distinguishing the species in the effusus group.</p><p>‡ Adult male of R. eminellobus and R. tuberculatus are very similar. Key above can partially separate the two species. Female, pupa and larva of two species are quite distinguishable.</p></div>	https://treatment.plazi.org/id/03CB87EF4C59697F9193F9F1FD85FC41	Public Domain	No known copyright restrictions apply.
