(here described and designated).</p> <p>Other species</p> <p>Brasilodopsis amazonica gen. et sp. nov. (here described).</p> <p>Etymology</p> <p>The name of the new genus is a contraction of ‘ Brasilo ’, after Brazil, the country from which it is here described, and ‘ dopsis ’, referring to the stem of Cypridopsis.</p> <p>Diagnosis</p> <p>Cp sub-triangular in lateral view, with LV mildly overlapping RV along all sides. LV anteriorly, ventrally and posteriorly with a well-developed, largely inwardly displaced inner list, anteriorly with a submarginal selvage. RV anteriorly with submarginal inner list, posteriorly with one inner list and a marginal selvage. A2 with natatory setae well-developed, reaching well beyond the end claws. T 1 in female with two short setae a; seta d present in female, absent in male; setae b absent in both sexes. T2 with one short seta d2, seta d1 absent. T3 distally with incompletely developed pincer organ, fourth segment fused with third segment. CR in female with cylindrical base.</p> <p>Differential diagnosis</p> <p>Brasilodopsis gen. nov. belongs to the cypridopsine genera where the LV overlaps the RV; only six other genera belong to that group (see Table 1). The new genus differs from Austrocypridopsis McKenzie, 1982, Cavernocypris Hartmann, 1964 and Pseudocypridopsis Karanovic, 1999 by the long natatory setae on the A2 (short to very short in the other three genera). It further differs from Austrocypridopsis in the shape of the base of the CR, (triangular in Austrocypridopsis, cylindrical in Brasilodopsis gen. nov.) and in the shape of the valves in lateral view (rectangular in Austrocypridopsis). Cavernocypris also has a triangular base of the CR and furthermore lacks all inner lists and selvages on both valves, while the T1 has a seta b (missing in Brasilodopsis gen. nov.). Pseudocypridopsis also lacks inner lists and selvages; while the CR is missing in both males and females. Brasilodopsis gen. nov. further differs from Cypridopsis s. str. Brady, 1867 by the general shape of the Cp (much broader in dorsal view in Cypridopsis), while the posteroventral inner list in the LV does not run (sub-)parallel to the valve margin in this latter genus (it does so in Brasilodopsis gen. nov.), while the anterior inner list in this valve runs less than halfway the anterior valve margin (all the way to the dorsal margin in Brasilodopsis gen. nov.). The base of the CR in Cypridopsis is triangular, while it is elongated in Brasilodopsis gen. nov. Neocypridopsis Klie, 1940 has a very different shape of the Cp (rather high and swollen in dorsal view), but more importantly has the fourth segment of the T3 separate from the third segment, much like in Candonidae. Tungucypridopsis Victor, 1983, finally, is ill-described which makes a comparison with the present new genus difficult. It appears to lack the inner lists on both valves, which are moreover much larger than in Brasilodopsis gen. nov. (0.6 mm versus 0.4 mm – see Table 2).</p> <p>Cyprettadopsis Savatenalinton, 2020 (placed in a separate tribe by this author) has a similar valve shape, including inner lists, but has (incomplete) marginal septae and a series of large ventral pores along the outer lists, which are both absent in Brasilodopsis gen. nov., while the T3 also has a separate fourth segment (fused into an incomplete pincer in Brasilodopsis gen. nov.).</p> </div>	http://treatment.plazi.org/id/03F687AFF070FFB7009DFC2BFC4EF84A	Public Domain	No known copyright restrictions apply.

Hemipenis outline similar in both species, but distal segments of prehensile palps with subtle differences.</p> <p>Ecology and distribution</p> <p>Brasilodopsis amazonica gen. et sp. nov. was recorded only from the Amazon River floodplain, in association with several aquatic macrophytes. The range of the water temperature was between 31.5 and 32.9°C. The pH range remained slightly acid (6.4 and 6.7 – hence possibly the decalcified valves). The ranges of electrical conductivity and dissolved oxygen were from 41.5 to 67.1 µS. cm-1, and from 0.4 to 3 mg.L- 1, respectively (see Table 4).</p> </div>	http://treatment.plazi.org/id/03F687AFF063FF90003AF9A4FDC3FB76	Public Domain	No known copyright restrictions apply.

As the tribe is monogeneric and the genus is monospecific, it is difficult to allocate the different characters and character states to the different taxonomic levels. It is expected that other species in this genus and other genera in this tribe will have basically the same body plan, with slight modifications in shape, size and chaetotaxy of segments in various limbs.</p> <p>Etymology</p> <p>The new species is named after the fact that much of the size, shape and chaetotaxy of the segments in the limbs is reduced, especially in the A1.</p> <p>Type material examined</p> <p>Holotype BRAZIL • ♀; Upper Paraná River floodplain, <a href="http://tb.plazi.org/GgServer/search?materialsCitation.longitude=-53.349&amp;materialsCitation.latitude=-22.77925" title="Search Plazi for locations around (long -53.349/lat -22.77925)">Manezinho Backwater</a>; 22°46′45.3″ S, 53°20′56.4″ W; 2 Mar. 2007; J.

The temperature range of these lakes at the time of sampling was 28.3 to 32.6°C, while the pH range was 5.8 to 7. The electrical conductivity range was 14 to 61 µS. cm-1, and the dissolved oxygen range was 1.5 to 7.6 mg.L- 1 (see Table 4).</p> <p>The species can be considered as rare in the area.</p></div> 	http://treatment.plazi.org/id/03F687AFF057FF950029FC33FD5CF976	Public Domain	No known copyright restrictions apply.
