            <p>Etymology.</p>
            <p>The new species is named after Botswana, where the specimens were collected.</p>
            <p>Taxonomic remarks.</p>
            <p> This and the following new species are included in the genus  Niambia since they show all the characters of the genus, except for lacking respiratory areas in the pleopod exopods. This condition may be due to a secondary reduction due to the humid environment of the caves where they occur. Most of the species of  Niambia are epigean and inhabit semi-arid habitats in South West Africa (Barnard 1932). </p>
            <p> In lacking the frontal line on cephalon,  N. botswanaensis sp. nov. resembles  N. duffeyi Ferrara &amp; Taiti, 1981 and  N. longiantennata Taiti &amp; Ferrara, 1991 from Ascension Island, as well as  N. septentrionalis Taiti &amp; Ferrara, 2004 from Socotra Island (Yemen). However, it is distinct in lacking pigmentation and eyes, and in the shape of the male pleopod 1 exopod without posterior point (compare fig. 11 in Ferrara and Taiti 1981; fig. 30 in Taiti and Ferrara 1991; and fig. 33D in Taiti and Ferrara 2004). </p>
            <p> Some specimens of this species from the type locality were sent to Dr. M. Javidkar in Adelaide for molecular analysis and were included in a phylogenetic cladogram as  Niambia sp. 1 (Javidkar et al. 2015). </p>
            <p>Ecological remarks.</p>
            <p>The Koanaka and Gcwihaba hills are located in the North-West District (or Ngamiland) of Botswana. The lithology was described by Williams et al. (2012) as Precambrian dolomites from the Damara Sequence. According to Thies and Lewis (2015) the surrounding environment (known as the Kalahari Thirstland) is semi-arid with shrub savanna vegetation and forms part of the Savanna Biome. Annual precipitation typically ranges between 400 and 500 mm and temperatures from -8.5 °C to 42.2 °C.</p>
            <p> The Koanaka and Gcwihaba hills collectively host four known caves with natural entrances, which include Gcwihaba Cave, a local tourist attraction formerly known as  Drotsky’s Caverns (Fig. 4A). Furthermore, using gravimetric surveys and exploration drilling, an additional five caves were discovered, opened and explored (Harvey and Du Preez 2014; Du Preez et al. 2015). One of these is  Diviner’s Cave, the type locality of  Niambia botswanaensis sp. nov. Initial exploration of  Diviner’s Cave commenced in 2011 after a 700 mm diameter vertical shaft (borehole) was drilled (Fig. 4B-E). This shaft is 41 m deep and enters the cave in a chamber called 'Entrance  Alcove’ (Fig. 4C, D). Upon initial exploration of the cave, high CO2 levels were encountered, especially in areas lower than the general cave development level. However, since the cave was allowed to vent following the drilling of the borehole, CO2 levels gradually decreased and facilitated further exploration. As can be expected, atmospheric conditions in  Diviner’s Cave and those with man-made entrances were quite distinct from the observed in local caves with natural entrances (Du Preez et al. 2015). All the caves associated with the Koanaka and Gcwihaba hills are protected and declared as Botswana National Monuments. </p>
            <p> Specimens of  Niambia botswanaensis sp. nov. were collected by hand in Calcite Baboon Chamber,  Diniver’s Cave. The collection site is located (Fig. 4F, G) at the one end of this chamber where large  Ficus cordata roots penetrate the cavity (Du Preez et al. 2015). Associated with this root system is a community of soil invertebrates that include pseudoscorpions (  Botswanoncus ellisi Harvey &amp; Du Preez, 2014), diplurans (  Japygidae ), centipedes (  Cryptops sp.) and termites. </p>
            <p> During sampling atmospheric conditions were measured using a Fluke 971 Temperature Humidity Meter. An average temperature of 28.5  ± 0.5 °C and relative humidity of 93  ± 5.4% were recorded in  Diviner’s Cave. </p>

            <p>Etymology.</p>
            <p>The new species is named after Ghaub cave, the type-locality of the species.</p>
            <p>Taxonomic remarks.</p>
            <p> Niambia ghaubensis sp. nov. differs from  N. botswanaensis sp. nov. by the telson with right-angled instead of obtuse apex, male pereopods 1-2 with a brush of setae on carpus and merus sternal margin instead of sparse setae, dactylus of pereopods with a thinner inner claw, and male pleopod 1 exopod cordiform instead of rounded. </p>
            <p>Ecological remarks.</p>
            <p> The Ghaub cave is the third largest cave in Namibia, with approximate 2.5 km of passages. It consists of an intricate net of labyrinthine conduits with different levels. The lowest level connects to the phreatic level; thus, some ponds are observed inside the cave. The cave is inserted in the dolomites of the Otavi geological group, dating from the upper Precambrian (Goudie and Viles 2015). The cave has a single entrance (Fig. 8A), in which there is currently a gate installed to prevent unauthorized entry. The  conduits’ morphologies are somewhat variable since they transect an intricate stratigraphy along the almost 40 m vertical gap within the rock (Fig. 8B, C). Although the lower levels of the cave are connected to the phreatic level, most of the cave remains dry. Yet, moist substrates occur in some areas by drip water from speleothems. Organic resources observed are mainly the guano produced by insectivorous bats, where invertebrates are usually concentrated. Specimens of  Niambia ghaubensis sp. nov. were only found in the deep sections of the cave, associated with moist substrates (Fig. 8D). Curiously, such areas were devoid of other invertebrates, and also of guano. Hence, it seems that this species is highly specialized, avoiding areas richer in organic matter and, thus, other invertebrate species (including predators). Individuals were observed freely walking on the cave floor. </p>
            <p> The Ghaub cave is currently used for touristic purposes, receiving visitors regularly. However, apart from the rudimentary stone stairway at the gate entrance in the first conduit, no other man-made structures are present in the cave. The only altered area in the cave due to the tourism is a small chamber at the lower level, which is quite moist with mud. In this chamber, locals used to make mud animals that were left in some parts of the chamber, forming curious sets of mud figures (Fig. 8E). Fortunately, the cave sections where  N. ghaubensis sp. nov. occurs are difficult to access, which minimizes the threat to this species by visiting tourists. The  region’s climate is considered as hot semi-arid (BSh), according to the updated Koppen-Geiger classification (Beck et al. 2018). According to historical data from 1982 to 2012, the average annual rainfall in the area ranges from 500 to 600 mm, with the wet season occurring from November to March (Merkel 2019). The cave is located in the "Angolan Mopane Woodlands" ecoregion (Dinerstein et al. 2017). The surface environment surrounding the cave is protected and located in a reserve that hosts tourists also for photographic safaris. The Otavi mountains are, in general, well preserved, with the land cover dominated by natural forests (Fig. 8F). </p>

            <p>Etymology.</p>
            <p>The new species is named after Namibia, where the specimens were collected.</p>
            <p>Taxonomic remarks.</p>
            <p> Niambia namibiaensis sp. nov. is easily distinguishable from  N. botswanaensis sp. nov. and  N. ghaubensis sp. nov. in having some gland pores on the lateral margins of the pereonites, a rounded apex of telson, a brush of trifid setae on the male pereopods 1-4 merus and carpus, and a different shape of the male pleopod 1. It also differs from  N. botswanaensis sp. nov. in having the dactylus of pereopods with a thinner inner claw. </p>
            <p>Ecological remarks.</p>
            <p> The  Märchen cave and the Ghaub cave are both located in the Otavi Mountains, about 56 km apart. The  Märchen cave presents a 12 m vertical shaft at the entrance with the maximum cave depth being 60 m. Farmers installed metal ladders to facilitate access to the cave (Fig. 12A-C). Specimens of  N. namibiaensis sp. nov. were only found in one of the deepest portions of the cave, under rocks on the floor. This was also the only area with noticeable moisture content (Fig. 12D). Since the visit to the cave occurred in the dry season, most of the  cave’s substrates were extremely dry. In the humid part of the cave, where the isopods were found, other invertebrates were also observed, including potential predators such as the troglophilic  Bothriuridae scorpion  Lisposoma josehermana Lamoral, 1979 and spiders. The cave was not visited for research purposes during the rainy season and therefore it is not possible to determine if the distribution of this species within the cave is subject to seasonality. However, they may likely present a wider distribution during the wet periods since there are many signs of water drips in the cave. Although other caves were also sampled in the same outcrop, no specimens of  N. namibiaensis sp. nov. were found. The external environment is well preserved (Fig. 12D) and even with the facilities to access the cave, there are no signs of human impact inside it. This species is not currently considered threatened. </p>
