Limnesia hesperia Lundblad 1930
No full textLimnesia hesperia Lundblad, 1930 New record — 1/0/0, Saut Sonnelle, Inini River, 3.668227°N, 53.960857°W, 28 Sept. 2017. Distribution — Peru (Lundblad 1930), Paraguay (Lundblad 1941), Surinam (Besseling 1949), French Guiana (this study). Remarks. According to Viets (1954b) 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 P4. However, Besseling’s material and illustrations (Besseling 1949) matches the original description of Lundblad (1930), and, therefore, we disagree with Viets (1954b).Published as part of K, Harry Smit, Pešić, Vladimir, K & K, Simon Clavier, 2022, Water mites from French Guiana, with the description of 14 new species (Acari: Hydrachnidia), pp. 1119-1153 in Acarologia 62 (4) on page 112

Clavier.</p> <p> <b>Remarks</b> — The specimen from French Guiana has less acetabula than the illustrated specimen of Lundblad (1943). 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.</p> <p> <b>Distribution</b> — Paraguay (Lundblad 1938, 1943), Brazil (Besch 1969), French Guiana</p> <p>(this study).</p>Published as part of <i>K, Harry Smit, Pešić, Vladimir, K & K, Simon Clavier, 2022, Water mites from French Guiana, with the description of 14 new species (Acari: Hydrachnidia), pp. 1119-1153 in Acarologia 62 (4)</i> on page 113

Zoobank: F8C2A2BE-90AE-4B30-98DD-73331F232C0B (Figures 8A–D) Material examined — Holotype female, Crique Aya, National Reserve La Trinité, French Guiana, 4.590557°N, 53.413572°W, 4 Nov. 2018, leg. S. Clavier (MNHN). 50 µm. Diagnosis (Male unknown) — The three pairs of acetabula widely separated from each other, first pair at level of postgenital sclerite, posterior two pairs lying far posteriorly; Cxgl-4 not extending far anteriorly; P2 with a blunt anteroventral projection covered by minute denticles. Description — Female – Idiosoma without plates or platelets, dorsally 810 long and 786 wide, ventrally 846 long. Coxae in three groups, anterior coxae posteriorly pointed. Cxgl-4 near incomplete suture line of Cx-III/IV, posterior to Cx-IV an area of secondary sclerotization (Figure 8A). Genital field 198 long with three pairs of widely separated acetabula, first pair of acetabula at level of postgenital sclerite; pregenital sclerite 146 wide. Acetabula (partly) surrounded by a small fringe of secondary sclerotization (Figure 8B). Length of P1-5: 31, 136, 100, 198, 42. P2 anteroventrally with a blunt projected, its tip covered by minute denticles; P3 ventrally and medially with denticles; P4 slender, ventrally with two widely separated setae (Figure 8C). Length of I-leg-4-6: 182, 178, 116. I-leg-5 anteroventrally with two pointed setae, unequal in size (Figure 8D). Length of IV-leg-4-6: 243, 251, 210. Swimming setae absent. Excretory pore surrounded by a small fringe of secondary sclerotization. Male – Unknown. Etymology — Named after the widely separated acetabula. Discussion — Unlike all other Hygrobatides species, Cxgl-4 are not extending far anteriorly. Moreover, none of the known species have the acetabula so widely separated as in the new species and P2 with a blunt anteroventral projection.Published as part of K, Harry Smit, Pešić, Vladimir, K & K, Simon Clavier, 2022, Water mites from French Guiana, with the description of 14 new species (Acari: Hydrachnidia), pp. 1119-1153 in Acarologia 62 (4) on pages 1131-113
