Epipleura reddish-brown, with double row of strong punctures in anterior part and single row of weaker punctures in posterior narrowed part, reaching to the end of fifth sternite. Prosternum bordered anteriorly, strongly punctured in the middle. Prosternal process gradually widening anteriorly, slightly narrowed in posterior part; about 1.9 times longer than wide at base; anterior edge margined, laterally grooved; moderately strongly and densely punctured (Figs. 4, 16, 17). Metaventral process with two well-defined, but slightly confluent impressions on both sides, not impressed in the middle; moderately punctured (Fig. 16). Metacoxal plates reaching to the fifth sternite, densely punctured. Fifth and sixth sternites densely punctured; last sternite punctured only at base (Fig. 4). Legs. Orange-brown to brown. Fore- and mid legs: femur basally narrowed, medially enlarged, surface covered with dense, coarse micropunctures; tibia with long hairs on inner margin, apically with two equal spurs; tarsi with 5 tarsomeres, the 5th longest, tarsal claws of equal length.

Left paramere in lateral view short and broad, subtriangular, almost as long as wide, with basal process narrow, and with apex angular; with a series of long setae and some sparse setae at the apex (Fig. 18). Right paramere in lateral view slender, moderately curved, base bilobed, apex rounded; inner margin with a series of large setae in the apical two thirds (Fig. 20). Etymology. This species is named in honor of Juan Antonio Régil Cueto, the PhD supervisor of the first author, a good friend and colleague, in gratitude for all the shared moments during our long friendship and in recognition of his contribution to the knowledge of water beetles. Distribution and habitat. Northern Brazil, currently only known in the state of Roraima (Fig. 21). Specimen was collected in a shallow pond with macrophytes covering the entire surface (Fig. 23). Taxonomic comments. Haliplus regili sp. n. can be distinguished from other neotropical species of Haliplus by the combination of characteristics of elytra, prosternal and metaventral processes and the male genitalia shape. The new species resembles H. langleyi Vondel & Spangler, 2008 and H. triplehorni Vondel & Spangler, 2008, but differs from these species in the shape of prosternal process (Fig. 16), gradually widening anteriorly (almost parallel in H. langleyi and H. triplehorni); male median lobe (Fig. 19), shorter and less curved downward in H. langleyi and H. triplehorni and right paramere (Fig. 20), without distal appendage (with distal appendage in H. langleyi and H. triplehorni.Published as part of Benetti, Cesar João & Hamada, Neusa, 2017, Two new species of Haliplus Latreille, 1802 (Coleoptera, Haliplidae) from Northern Brazil, pp. 584-592 in Zootaxa 4282 (3) on pages 587-592, DOI: 10.11646/zootaxa.4282.3.10, http://zenodo.org/record/82787

Basal tubercle of D 1 -seta with sclerotized beak (left) and base of D 2 - and D 3 -setae (right) with large tubercles on tergite III. C. Abdomen, in dorsal view. Abdomen (Fig. 3 C). Tergite I–II with small field of very fine shagreen restricted to central area; tergite III–VIII with field of shagreen restricted to central posterior area; genital sac of male with shagreen on basal half. Tergite I with 4 pairs of D-setae, tergite II with 5 pairs of D-setae, all these setae short and taeniate. D 1 -setae somewhat taeniate on tergite III, 171 µm long; sclerotized and spiniform on tergite IV–VII, 74, 84, 90 and 96 µm long respectively, all arising from a more or less distinct tubercle; basal tubercle of D 1 -seta large with sclerotized beak on tergite III and IV (Fig. 3 B).

The male imago of F. mayumiae sp. n. resembles F. c r y p t a, since both have iridescent eyes and a similar coloration pattern, but can be differentiated by the distribution of the setae on gonostylus and the number of antepronotals and scutellar setae. The pupa of F. m a y u m i a e sp. n. resembles the pupa of F. nipponica by having all abdominal segments with shagreen and 5 LS setae on segment VIII, but in F. mayumiae sp. n. the anal lobe has fringe on both the outer and inner border, contrasting with F. nipponica that has fringe only on outer border. Notes on species biology. The specimens of Fittkauimyia mayumiae sp. n. were obtained from decayed wood collected in small black water streams. Probably, larvae of the new species inhabit the surface of wood or in clefts in the bark, in which they are searching for or waiting for preys. The stream where the larvae were collected had an average width of 1.8 m, average depth of 0.14 m and average flow of 0.14 ms - 1, and was characterized by acidic water (average pH = 4.74), low conductivity (average = 15 μScm - 1), high concentration of dissolved oxygen (average = 6.45 mgL - 1) and low temperature variation (average = 25.5 °C). The dominant substrate types in the stream beds were sand (average = 50 %), coarse litter (average = 30 %) and fine litter (average = 12 %).Published as part of Dantas, Galileu P.

No full textSmicridea (Smicridea) jeaneae Desiderio, Pes & Hamada sp. nov. urn:lsid:zoobank.org:act: B3B2E393-F3E0-4FAD-8838-32481EB11877 Figs 3, 11 – 12 Diagnosis Smicridea jeaneae sp. nov. also belongs to the albosignata complex.Among the species in this complex, it is most similar to S. bulbosa Flint, 1974 from Suriname based on the strong, parallel, pointed apicomesal lobes on tergum X and the short, slender apical segment of the inferior appendage with slightly acute apex. In both species the claw-shaped internal dorsolateral plates of the phallic apparatus are as long as the basal width, but in S. jeaneae sp. nov. the plates are straight mesally, while in S. bulbosa they are curved. In addition, the phallotremal sclerite of the phallic apparatus has a hastate shape distally in dorsal view and is kidney-shaped in lateral view in the new species, but is strap-like in dorsal view and rod-like in lateral view in S. bulbosa. Smicridea jeaneae sp. nov. can also be recognized by the three stout apical spine-like setae on the basal segment of the inferior appendage, one long seta dorsally and two mediumsized setae on the mesal margin. Etymology This new species is named in honor of Dr Jeane Marcelle Cavalcante do Nascimento (Instituto Nacional de Pesquisas da Amazônia, INPA – Brazil) for her valuable friendship, cooperation in the field and the laboratory, and in gratitude for her help in collecting material during the doctoral studies of the first author.

The Literary Polemic Hamada – Mináč and Its Contemporary Context
No full textThe presented article reconstructs the literary polemic between the writer and essayist V. Mináč and the literary critic M. Hamada which took place in the liberal enviroment of the first half of the 1960s in Slovakia and became emblematic of that period of time. The author pays attention to its impact as well as the events and the writings preceeding it. The central subject of the polemic was the category of estrangement in the context of various interpretations of Marxist philosophy. It also helps identify the political and cultural processes forming the intellectual climate of the 1960s. On the one hand it became a part of the wide-ranging social discussion about the critical „acknowledgement“ of the Stalinism´s legacy, which continued until its violent interruption by Normalization after 1968, on the other hand, it made space for new ideological, philosophical and aesthetical initiatives. However, the polemic also raised other issues, which have reached beyond the context of the period of time in question and are permanently present in the current discussions about finding alternatives to technological rationality and other strategies of the „Post-Modern“ power (Foucault, Derrida, Deleuze, Bauman, Žižek)

ANALISIS SEMIOTIKA CHARLES MORRIS DALAM LAGU SAYYIDI AR-RAIS KARYA HAMA MESHARY HAMADA
No full textThis study aims to describe the meaning of the song Sayyidi Ar-Rais in the work of Hama Meshary Hamada using Charles Morris Semiotics analysis which divides the analysis into 3, namely Semantics, Pragmatics, and Syntax. The author uses descriptive qualitative research in describing the research data. The data taken from Zain Ramadhan Channel's youtube account was collected through several stages: first, the author documented the lyrics of the Sayyidi Rais song taken from the data source; second, the writer chooses several song stanzas as the corpus of analysis; third, the authors classify the data and determine the final data. The data were analyzed by Charles Morris's theory. The result of this research is that it can be concluded that the data analyzed by Charles Morris's theory has 3 divisions: Semantics, Pragmatics, and Syntax. In terms of semantics, the meaning of the quote in the song has a symmetrical relationship between the signifier and the signified. From a pragmatic point of view, it is found what the meaning of the speech in the quotes from Sayyidi Ar-Rais's song is. Meanwhile, in terms of syntax, the sentence structure of this song tends to be simple and conforms to the standard Arabic structure

Systematic remarks. Borkent (1984) described a pupal morphotype (“pupal form one”) that was associated with the genitalia of a male, probably pharate, indistinguishable from S. bacrionis Borkent. According to the author the two species could be differentiated by pupal features, which in the morphotype have spicules on the posterior region of the anal lobes, missing in the pupae of S. bacrionis. The pupa of S. bare sp. n. has such spicules on the anal lobes, but the male can be distinguished from S. bacrionis by the size of the superior volsella, that in the first species does not exceed the apex of the gonocoxite. The new species is also similar to S. triannulatus Borkent by the pigmentation of the thorax and wings and by the general morphology of the hypopygium. However, S. bare sp. nov. has the preapical constriction of T IX more pronounced, gonostylus with constant width along its length, hind tibia with one brown band, abdominal brown pigmentation on posterior margin of T II–III and posterolateral margin of T VIII, whereas S. triannulatus has the preapical constriction of T IX less pronounced, gonostylus with a preapical swelling, hind tibia with two brown bands, abdominal brown pigmentation on very lateral and posterior margins of T II–IV and posterior margin of T VI. Notes on biology of the species. The stream where S. bare sp. nov. was collected is a small typical blackwater stream of the Amazon lowlands forest, with an average width of 1.5 m (range: 0.70–2.20), average depth of 0.10 m (range: 0.033–0.240) and average flow of 0.02 m 3 /s (range: 0.004–0.148). These water courses are characterized by acidic black water (average = 4.50, range: 2.60 –6.00), low conductivity (average = 7.60 µS/cm, range: 6.80–9.95), high concentration of dissolved oxygen (average = 6.50 mg /L, range: 5.12–7.10) and low temperature variation (average = 24.6 C, range: 23.2–25.5). The opening of the forest canopy was small (average = 0.07 %, range: 0.02–0.19) and the dominant substrate types in the stream beds were sand (average = 31 %, range: 3– 61), coarse litter (average = 28 %, range: 6–50) and fine litter (average = 13 %, range: 0–41).Published as part of Dantas, Galileu P.

Comprehensive Analysis of Minimally Invasive Management for Persistent Anterolateral Ankle Pain: A Systematic Review
No full textPersistent anterolateral ankle pain is a debilitating condition often associated with soft tissue impingement following inversion injuries. It can lead to significant limitations in daily activities and overall quality of life, particularly in individuals with chronic ankle instability. This systematic review examines the efficacy and safety of minimally invasive arthroscopic decompression techniques in managing anterolateral ankle impingement syndrome. A total of 246 cases from nine studies were reviewed, involving 135 males with a mean age of 29.6 years and an average follow-up period of 29.5 months (range: 15-83.7 months). Outcomes were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) scores and Meislen criteria. The AOFAS scores improved significantly from a mean of 40.75 preoperatively to 84.2 postoperatively, reflecting substantial functional recovery. Based on the Meislen criteria, 124 cases (50%) were rated as excellent, 71 (29%) as good, 14 (6%) as fair, and three (1%) as poor. Postoperative mobility was restored to normal in 130 cases, with complications reported in 24 cases (9.8%), including hypoesthesia, infections, intra-articular haemarthrosis, scar tissue formation, nerve irritation, and persistent pain or numbness. Patient satisfaction was high, with most patients reporting significant improvements in pain relief and functional capacity. Arthroscopic decompression is a safe, minimally invasive, and effective intervention for managing persistent anterolateral ankle impingement, offering substantial improvements in pain, mobility, and overall function with low morbidity and a manageable complication rate. This approach is an invaluable option for patients unresponsive to conservative treatments.This is an open access article distributed under the terms of the Creative Commons Attribution License CC-BY 4.0., which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.RDUH staff can access the full-text of this article by clicking on the 'Additional Link' above and logging in with NHS OpenAthens if prompted
