Limnesia 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 1124, {"references":["Lundblad O. 1930.

Limnesia szalayi K. Viets, 1955 syn. nov. Material examined — Limnesia patens. Syntypes: Two males, three deutonymphs, Kratersee Telaga, Buitenzorg, Java, 21.11.1928, (Type, slide 45621, SMF); two males, one female, Sindanglaja Quelle, Buitenzorg, Java, 21.11.1928 (Types, slide 45622, SMF). Limnesia szalayi. Holotype female, Kuranda, N Queensland, Laird coll., 13.6.54 (slide 45696, SMF). New record — Queensland. 1/1/0, Spear Creek at crossing with Bypass Road, Cape York Peninsula, 12°03.206′ S 142°39.138′ E, 76 m a.s.l., 23 Oct. 2014. Remarks — The specimens from this study match the description of K. Viets (1935) well. K. Viets (1955) described a very similar species from northern Queensland, i.e. L. szalayi. The description of the latter species was based on one female only, and Viets didn′t compare it with other species. Moreover, the holotype of L. szalayi was fixed in ethanol, which makes it often difficult to see the morphological structures well. Cook (1986) noticed the similarity between the two species. When comparing the original descriptions, the only difference I find between the two species is that L. patens has no posteromedial platelet (K. Viets 1935), and in L. szalayi an indistinct platelet should be present (K. Viets 1955). I examined the holotype and only known specimen thus far of L. szalayi, but I do not see a posteromedial platelet. In the shape of palp and genital field the two species are identical. Therefore, I propose to synonymize L. szalayi with L patens. Distribution — Limnesia patens is widespread, and has been reported from Java, Indonesia (K. Viets 1935), India (Cook 1967) and Burma (Lundblad 1969).

Dorsum with eight pairs of glandularia, six of these on the dorsal shield. Cx­III with a relatively long, straight medial margin. Gnathosoma attached to a protrusible tube. Acetabula of separate genital plates. Description. Male: Idiosoma dorsally 571 long and 389 wide, ventrally 591 long. Integument lineated, eyes and integument without pigment. Dorsal shield with six pairs of glandularia and the postocularia, dorsal furrow with two pairs of glandularia. Gnathosomal bay pointed posteriorly, Cx­I fused medially. Cxgl­4 on Cx­III, near suture line of Cx­III/IV. No ridge present anterior to insertion of fourth legs. Genital field 118 wide, gonopore 34 long, with three pairs of glandularia, these lying on curved, indistinct genital plates. Gnathosoma elongated, attached to a protrusible tube. Length of P1­5: 20, 64, 60, 90, 40. Palp segments dorsal without stout setae, P2 ventrally with a short, relatively stout seta. Length of I­leg­4­6: 76, 98, 131. Length of IV­leg­4­6: 84, 90, 92; IV­leg­6 with a terminal seta, 62 long. Excretory pore incorporated in ventral shield. Etymology. Named for its superficial resemblance to L. zelandica Cook, 1983. Remarks. With the key of Cook (1983) the new species keys out as L. testacea Hopkins, 1969. Differences with the latter species (in brackets) are the long medial margin of Cx­III (short), no ridge anterior to insertion of fourth legs (with ridge) and the gonopore is shorter. A second species with the dorsal shield with six pairs of glandularia is L. zelandica Cook, 1983. This species has the gnathosoma attached to a protrusible tube too. Differences with the new species (in brackets) are the presence of three pairs of glandularia in the dorsal furrow (two pairs), the presence of a ridge anterior to the insertions of the legs (no ridge), rounded medial margins of Cx­III (straight), and the integument is pigmented (not pigmented).

This paper treats nine water mite species of Limnesia now known to occur in the Netherlands. Two species are new for the Netherlands: L. marmorata and L. curvipalpis. Limnesia angustata, previously considered a variety of L. maculata and raised to species level later on in the 20th century, fits the original description of L. marmorata and is similar to the type material of L. marmorata. Therefore L.angustata is synonymised with L. marmorata. A key to the nine species of the Netherlands is given as well as an overview of the ecology and, where available, information on the biology. Limnesia marmorata is very common, occurring in ditches, lakes and rivers, whereas L. curvipalpis is rare, being found in moorland pools and a eutrophic canal. With both latest additions, the Dutch list of water mite species now numbers 248.

Limnesia (Limnesia) connata Koenike, 1895 Limnesia jaczewskii Biesiadka, 1977, nov. syn. According to the original description (Biesiadka 1977), Limnesia jaczewskii differs from L. connata in body size, the position and size of the acetabula, the shape of the palp and the attachment and number of swimming setae. Furthermore, L. jaczewskii has two posterodorsal platelets, while L. connata should have only one. However, Tuzovskij (1997) showed that populations of L. connata include specimens with both, unpaired and paired dorsal platelets. According to Biesadka (1977) the palp of L. connata should be more slender, but Tuzovskij���s (1997) L. connata have a similar palp as L. jaczewskii. As no correlation can be found between these character states and body size, position and size of the acetabula and swimming setation of legs, Limnesia jaczewskii should be considered a junior synonym of L. connata., Published as part of Smit, Harry, Gerecke, Reinhard, Pe��i��, Vladimir & Gledhill, Terence, 2015, On the taxonomic state of water mite taxa (Acari: Hydrachnidia) described from the Palaearctic, part 3, Hygrobatoidea and Arrenuroidea with new faunistic data, pp. 542-552 in Zootaxa 3981 (4) on page 543, DOI: 10.11646/zootaxa.3981.4.5, http://zenodo.org/record/242595, {"references":["Biesiadka, E.

Limnesia (Limnesia) arevaloi arevaloi K. Viets, 1918 Limnesia martianezi Lundblad, 1962 ��� nov. syn. Material examined. Holotype female, SMNH 6013, Tenerife, spring Marti��nez near Puerto de la Cruz, Lundblad 24.04. 1960. La Gomera, Cedro u. Caseria, kl. Saltadero, Moos, 11.09. 1992 Beyer coll. (1 / 1 /0). In the original description, Lundblad (1962 a) compared this species only with L. atlantica Lundblad, 1942 from Madeira. He proposed as a diagnostic difference to that species the insertion of the ventral peg-like seta on P- 2 on a short socket, and a more slender shape of the gnathosoma and chelicera. All these character states are equally found in L. arevaloi, a species in good agreement also with regard to the variability of idiosoma and appendage measurements (Gerecke 1991). Under all morphological aspects there is no doubt that L. martianezi is a junior synonym of L. arevaloi. On the Canary islands, the presence of the latter (sub)species (characterized by immovable genital flaps in the male sex) is now confirmed also by the new records from Gomera., Published as part of Smit, Harry, Gerecke, Reinhard, Pe��i��, Vladimir & Gledhill, Terence, 2015, On the taxonomic state of water mite taxa (Acari: Hydrachnidia) described from the Palaearctic, part 3, Hygrobatoidea and Arrenuroidea with new faunistic data, pp. 542-552 in Zootaxa 3981 (4) on page 543, DOI: 10.11646/zootaxa.3981.4.5, http://zenodo.org/record/242595, {"references":["Lundblad, O.

Paratype: one female, same data as holotype. (RMNH). Diagnosis. Idiosoma with two large medial plates surrounded by a pair of frontal plates and five pairs of lateral and posterior plates; first and second legs modified, palp very stocky. Description. Female: Idiosoma ventrally 980 (1004) long and 656 (637) wide, dorsally 923 (964) long. Integument soft. Dorsum with two large medial plates, anterior plate 259 long and 227 wide, posterior plate 267 long and 300 wide, surrounded by a pair of frontal plates and five pairs of lateral and posterior plates varying in size, with the middle pair of plates being the largest.

Glandulae Limnesiae with their associated setae located medially on third coxal plates. Third and fourth coxal plates fused to one plate. Genital field 204 long and 164 wide, with three pairs of acetabula, lengths of Ac- 1���3 66, 50 and 70, respectively; each genital flap with five small setae. Pregenital sclerite 160 wide, postgenital sclerite a large plate 216 long and 227 wide. Posteriorly of postgenital plate two pairs of large plates, anterior pair 176 long, posterior pair 150 long.

IV-leg- 3 and - 4 ventrally with six and seven pinnated setae; IV-leg- 6 ending in a long seta. Legs I���III with a claw, without claw blade and with a minute clawlet; swimming setae absent. Male: Unknown. Etymology. Named for the high number of dorsal and posteroventral plates. Remarks. Within the genus Limnesia, the occurrence of plates and platelets is not unusual. However, most species have two large dorsal plates, occasionally the anterior plate is divided. A configuration of the dorsal and ventral plates as in the new species, is not found in any other Limnesia species. Other unusual characteristics are the very stocky palp, not found in other species of the Oriental and Australasian regions, and the modified first and second leg. It is possible that the new species must be placed in a subgenus of its own, but this can only be decided after the male is known.
