03F487E078260835AEF37B2E58046315.taxon	description	Description — Male – Idiosoma dorsally 616 long and 494 wide, ventrally 680 long. Dorsal shield 567 long and 437 wide, with tightly fitting plates and platelets, consisting of a relatively small, anteriorly pointed plate with one pair of glandularia (dc- 1), a large central plate (dc- 2 + 3), 288 long and 275 wide, with the anteriorly located postocularia. These two unpaired plates surrounded by six platelets without glandularia and three pairs of small platelets, each with a glandularium (Figure 1 A). Venter with five pairs of tightly fitting plates as well as two pairs of platelets. Genital field on an unpaired, anteriorly pointed plate with one pair of glandularia (pregen). Posterior to the latter plate a pair of small elongated plates without glandularia or setae, an unpaired elongated platelet with the excretory pore (postgen) and more posterior a small unpaired platelet (Figure 1 B) and Vgl- 3. Genital field 98 long and 129 wide, with numerous small acetabula. Near posterior margin of venter two pairs of bar-shaped sclerites, each with a glandularium. Length of P 1 - 5: -, -, 50, 34, 18. P 4 stocky (Figure 1 C). Length of I-leg- 4 - 6: 80, 90, 77. Length of IV-leg- 4 - 6: 150, 102, 82. Legs without swimming setae.

03F487E078260835AEF37B2E58046315.taxon	etymology	Etymology — Named for its wonderful appearance.	en	K, Harry Smit, Pešić, Vladimir, K, K, Simon Clavier (2022): Water mites from French Guiana, with the description of 14 new species (Acari: Hydrachnidia). Acarologia 62 (4): 1119-1153
03F487E078260835AEF37B2E58046315.taxon	discussion	Discussion — In males of this genus the genital field is lying on a plate with one pair of glandularia (Cxgl- 2), in females Cxgl- 2 are lying each on a small platelet. The new species is most close to R. testudo Lundblad, 1936, R. dividuus Lundblad, 1941 and R. armiger De Castro, Proctor & Lofego, 2022. From these species the new species differs in the presence of two pairs of dorsal plates posterior to the large postocularia plate. Rhynchohydracarus testudo has only one pair of plates, R. dividuus and R. armiger have one pair of plates and an unpaired plate posteriorly to the postocularia plate. Moreover, the pair of small platelets without glandularia or setae posterior to the genital plate is absent in the forementioned species.	en	K, Harry Smit, Pešić, Vladimir, K, K, Simon Clavier (2022): Water mites from French Guiana, with the description of 14 new species (Acari: Hydrachnidia).

According to Viets (1954 b) Besseling’s material from Surinam does not belong to this species. When compared with the description in Lundblad (1941) there are indeed differences in the setation of P 4. However, Besseling’s material and illustrations (Besseling 1949) matches the original description of Lundblad (1930), and, therefore, we disagree with Viets (1954 b).	en	K, Harry Smit, Pešić, Vladimir, K, K, Simon Clavier (2022): Water mites from French Guiana, with the description of 14 new species (Acari: Hydrachnidia).

Dorsal shield with three pairs of glandularia, near Dgl- 1 a short ridge (Figure 3 A). An indistinct lineation visible on the dorsal shield. Coxae fused with ventral shield, suture lines of coxae incomplete ; anterior coxae with short apodemes. Vgl- 4 located medially of suture line Cx-III / IV (Figure 3 B). Genital field 120 long, not incorporated in the ventral shield, with three pairs of acetabula. Length of P 1 - 5: -, 80, 51, 104, 28. P 2 ventrally with a stout seta on a short tubercle (Figure 3 C).

03F487E078220831AEF37A2758F663EC.taxon	discussion	Remarks — Besseling (1949) stated that the ventral seta of P 2 is inserted directly on the segment, without a setal tubercle. Examination of the holotype shows that this is not correct. The seta of P 2 is inserted on a distinct setal tubercle. Besch (1969) described a second species of this subgenus, i. e. Limnesia magnipora Besch, 1969. The only difference we see with L. surinamensis is the ridge near Dgl- 1, which is more near the anterolateral margin of the dorsal shield. However, we think this is due to the way Besch illustrated the species. L As. magnipora is in all other characters similar to L. surinamensis, we propose to synonymize the two species.	en	K, Harry Smit, Pešić, Vladimir, K, K, Simon Clavier (2022): Water mites from French Guiana, with the description of 14 new species (Acari: Hydrachnidia).

Lundblad (1943) didn′t give the number of acetabula, but based on his illustration the specimen from Paraguay has the anterior genital plate with 4 - 6 acetabula and the posterior genital plate with 11 - 12 acetabula. The female from French Guiana has the anterior genital plate with two acetabula, and the posterior plate with eight acetabula. However, nothing is known about the variation in the number of acetabula. Therefore, we have assigned our specimen to Lundblad’s species.	en	K, Harry Smit, Pešić, Vladimir, K, K, Simon Clavier (2022): Water mites from French Guiana, with the description of 14 new species (Acari: Hydrachnidia).

03F487E07832082FAEF37DDD5E4267A8.taxon	etymology	Etymology — Named after the Tanaru Indian or the Man of the Hole, the last member of an uncontacted indigenous people of the Amazon rainforest. The name is a noun in apposition. Discussion — With regard to shape of gnathosoma (relatively long, gnathosomal rostrum triangular-conical, posterior margin with a cleft) Geayia tanaru sp. nov. resembles G. major sp. nov. (see below). The latter species can be separated in a major dimensions, dorsum and venter without a distinctive colour pattern and posterior margin of gnathosoma with a U-shaped cleft, not flanked by a pair of lateral angular flange-like extensions as in G. tanaru sp. nov.

03F487E0783E082DAEF379E45E4262CE.taxon	discussion	Discussion — With regard to the shape of gnathosoma, the new species from French Guinea most resembles G. avinotata K. Viets, 1959, a species originally described from Igarapé Curi of the Amazon region of Brazil (Viets 1959). The latter species can be separated by the characteristic colour pattern of the dorsal shield (colour dark violet with a light-yellow marking in the form of a bird in flight as illustrated in the original description, see Figure 17 G). The specimen from Comtu River differs from the type specimen in smaller dimensions, and a divided posteromedial patch on the dorsal shield (compare Figures 20 G and 20 J) and the basal sclerites of the acetabula are more sclerotized (compare Figures 16 B and 17 B). It is possible that these differences are age-related, but the taxonomic position of these populations should be also checked by the application of molecular techniques.	en	K, Harry Smit, Pešić, Vladimir, K, K, Simon Clavier (2022): Water mites from French Guiana, with the description of 14 new species (Acari: Hydrachnidia).

03F487E0783E0814AEF37EB75E736675.taxon	discussion	Discussion — With regard to the shape of the gnathosoma (elongated with a subrectangular gnathosomal rostrum, posterior margin with a U-shaped cleft, not flanked by a pair of lateral extension), the new species from French Guinea most closely resembles G. micronycha K. Viets, 1954. The latter species was originally described based on two male specimens from Rio Ipojuca near Escada (Pernambuco State) in northeastern Brazil (K. Viets 1954 a). Later on, K. Viets (1959) described the female of G. micronycha from Igarapé Caranã in the Amazon region. From the new species from French Guinea, G. micronycha (in parentheses measurements from K. Viets 1954 b and K. Viets 1956) differs in the dorsal shield with a dark blue patch forming a cross-shaped pattern, and a yellow mushroom-like shaped patch with a central pair of glandularia in the middle of the cross-shaped figure, male genital field elongated, elliptic, distinctly longer than wide (L / W 228 / 157), and in both sexes the gnathosoma is more elongated (L / W 437 / 85 in ♂, 460 / 87 in ♀), posteriorly strongly tapering (see Figures 141 in K. Viets 1954 a and Figure 41 in K. Viets 1959).	en	K, Harry Smit, Pešić, Vladimir, K, K, Simon Clavier (2022): Water mites from French Guiana, with the description of 14 new species (Acari: Hydrachnidia). Acarologia 62 (4): 1119-1153
