Length 1.6–1.7 mm; maximum width 0.9–1.0 mm. Body slightly narrower than in <i>P. sinbad</i> (Fig. 2); dorsal pubescence shorter and lessdense, more silvery than golden. Pronotum slightly more transverse (ratio median length / width at base = 0.42–0.46). Eyes very flat, hardly visible from above. Eye border very prominent, especially next to insertion of antennae. Lateral border of pronotum less marked. Elytral border finer than in <i>P. sinbad</i>; elytral margin with acute denticles from median part to elytral locking device (not visible from above).</p> <p> Male genitalia (Fig. 8). Median lobe of the aedeagus slightly shorter than parameres, apex acuminate. Parameres as long as phallobase; apex of parameres straight. Phallobase shorter than in <i>P. sinbad</i> sp. nov.; base asymmetrical, with long struts, almost as long as phallobase.</p> <p> Female genitalia (Fig. 9): ovipositor longer than in <i>P. sinbad</i> sp. nov., with a marked angle in median region.</p> <p> <b>Etymology.</b> Named after the ancient Kingdom of the Sabaeans, in what is nowadays Yemen and north Ethiopia, with an area similar to the distribution of the new species; adjective.</p> <p> <b>Collection circumstances.</b> Most specimens were collected at light. The type locality (Jabal Bura, Fig. 15C) is a stream on stony substratum in an area with dense scrubland and palm trees.</p> <p> <b>Distribution.</b> Known from continental Yemen and Jordan, likely to be present in Ethiopia (Fig. 16).</p> <p> <b>Remarks.</b> We could not appreciate any difference in the external morphology or the male and female genitalia between the specimens from Jordan and Yemen, but did not include them as paratypes due to the scarcity of the material for study. The female from Ethiopia is also identical to those from Yemen, including the shape of the ovipositor and spiculum ventrale, but due to the absence of males its identity remains uncertain. According to the general shape of the ovipositor, <i>P. sabaeanus</i> sp. nov. seems to be related to some Afrotropical species (e.g. <i>P. congoensis</i> Delève, 1968) (DELÈVE 1968), although this author did not note the presence of denticles in the elytral margin in any of the African species of the genus.</p>Published as part of <i>Hernando, Carles, Ribera, Ignacio & Csic, 2014, The Limnichidae (Coleoptera) of the Arabian Peninsula and the island of Socotra, pp. 173-189 in Acta Entomologica Musei Nationalis Pragae 54</i> on pages 178-180, DOI: <a href="http://zenodo.org/record/5312492">10.5281/zenodo.5312492</a>

Morphology of the aedeagus characteristic, with the endophallus composed of three structures: (1) two very long, stout, inwardly curved lateral spines (2) central, slightly sclerotised, Y-shaped piece (3) cluster of variably sized stout spines, running along central part of the basal bulb.</p> <p> <b>Description. Male.</b> Body (Fig 1) entirely reddish brown, maxillary palps, antennae and legs lighter; body length: 1.2–1.36 mm. Dorsal surface of body covered with long golden semi-erect setae, except disc of head and pronotum which are glabrous with some longer setae on lateral margins of head and pronotum. <b>Head</b> sub-triangular with tempora rounded, wider than long (0.25–0.26/ 0.21–0.23 mm), covered with dense, semierect setae. Frontal rostrum distinctly wider than long (0.1–0.12/ 0.07–0.08 mm); antennal tubercles well-developed, median depression narrow and shallow. Vertex convex, with distinct median ridge. Eyes very small (microphthalmic), with only three ommatidia. Maxillary palpi (Fig.1) short; palpomeres II and III with protruding tubercles; palpomere segment IV 0.19 mm long, pedunculate at base, widest in middle and narrowed to apex with dense, short, recumbent setae (Fig. 2). Antennae (Fig. 4) 0.66 mm long; scapes much longer than wide (0.19/ 0.04 mm), cylindrical in shape, slightly curved at base and gradually widening towards apex; pedicel globular, longer than wide (0.07/ 0.04 mm); antennomere 3 slightly longer than wide (0.04/ 0.03 mm); antennomeres 4–8 spherical, (diameter 0.03mm); antennomeres 9 slightly wider than long (0.04/ 0.03 mm); antennomere 10 slightly wider than long (0.05/ 0.04 mm); terminal antennomere longer than wide (0.13/ 0.08 mm) and pointed at apex. <b>Pronotum</b> as long as wide, or longer than wide (0.28–0.3/ 0.25–0.3mm), about one and a half times as long as head and about the same width, or somewhat wider, maximum width at the middle; median antebasal fovea absent; lateral antebasal foveae well-defined, connected by well-defined, curved antebasal sulcus. <b>Elytra</b> almost equal in length and width (0.49-0.51/ 0.51-0.55 mm), slightly widened from anterior to posterior margin, twice longer (at suture) than pronotum; each elytron with two basal foveae; sutural striae entire, well-defined; discal striae absent. <b>Abdomen</b> slightly narrower than elytra; first two visible tergites (IV–V) equal in length. <b>Legs</b> long and slender; all tibiae simple; hind tibiae slightly curved in apical third; base of the profemora with a short series of tubercles on their internal margin (Fig. 6). <b>Aedeagus</b> (Fig. 7) elongate, symmetrical; parameres long, narrow and sharply pointed at apex, with three preapical setae of different lengths (Fig. 7a); endophallus rather complex and consisting of following structures: (1) two very long, stout, inwardly curved lateral spines (Fig. 7b); (2) central, slightly sclerotised, Y-shaped structure, with both ends lobed and broadly paddle-shaped (Fig. 7c); (3) cluster of variably sized stout spines, running along central part of the basal bulb to apical end of two lateral spines (Fig. 7d). Aedeagus with evaginated internal sac has very different appearance (Figs 8–9), parameres folded inwards, practically touching both apices (Fig. 8a), all structures of the internal sac projecting outwards, with the two large lateral spines perpendicular to the basal lobe (Fig. 8b–9b), the Y-shaped piece projecting completely forward, remaining as the most apical part of the aedeagus (Fig. 9c) and the central spine cluster folded downwards (Fig. 9d).</p> <p> <b>Female.</b> Similar to males but with wider antennal pedicel (Fig. 5); with palpomere IV larger, distinctly longer and asymmetrical (Fig. 3).</p> <p> <b>Differential diagnosis.</b> By the morphology of the aedeagus, with the internal sac composed of three groups of symmetrical structures: the two very long and slender lateral spines, the Y-shaped central piece and the cluster of robust central spines, <i>T. antojandro</i> <b>nov. sp.</b> is comparable to the species of the <i>Tychobythinus urgellesi</i> group (sensu Besuchet, 1974). Further, this group is characterized by the dorsally flattened head, the relatively large frontal rostrum with the shallow median depression. The group is composed of three troglobitic and microphthalmic species: <i>T. urgellesi</i>, <i>T. espanoli</i> and <i>T. muntani</i>, all of them distributed and known from few caves in the northeastern Iberian Peninsula (Bellés, 1984; Outerelo & Gamarra, 2006; Pallisé, 2021). <i>T. antojandro</i> <b>sp. nov.</b> is distinguished from all of these by the aedeagus with parameres longer and more acuminate, and by the different structure of the endophallus (Figs. 7–9). For illustrations of aedeagi of <i>T. urgellesi</i>, <i>T. espanoli</i> and <i>T. muntani</i>, see Besuchet (1974).</p> <p> <b>Etymology.</b> The new species is dedicated to the kids and brothers Antonio and Alejandro Pérez, sons of the junior author (TP), who actively participated in the discovery and capture of this new species. The specific epithet was proposed by them and is composed by the combination of both first names forming the acronym “antojandro”; noun in apposition.</p> <p> <b>Habitat.</b> The species was discovered in the G.E.V.-2 cave, with a total length of only 50 m and a maximum slope of 15 m. However, this small cave harbours a large terrestrial subterranean arthropod community, with 23 species recorded so far (Pérez <i>et al</i>. 2020). These species include mainly troglophilic elements and few troglobitic species or species closely linked to the subterranean habitat. Probable cave specialist would include the cricket <i>Petaloptila</i> (<i>Zapetaloptila</i>) <i>mogon</i> Barranco, 2004 (Orthoptera), known only from six caves in the province of Jaén (Barranco, 2013), and the ant <i>Aphaenogaster cardenai</i> Espadaler, 1981, (Hymenoptera) much more widely distributed in southern Spain, but, for the moment, only found in caves and shallow subterranean habitats (Ortuño <i>et al</i>. 2014). Recently, a single specimen of this ant has been found in an epigean habitat, but this seems to be an incidental finding (Rodríguez, 2022).All the specimens of the new species were captured under stones or wandering around a large column located in the central sector of the cave (Figs 10–11).</p>Published as part of <i>Hernando, Carles & Pérez, Toni, 2023, Tychobythinus antojandro sp. nov., a new troglobitic species of Pselaphinae (Coleoptera: Staphylinidae) from Andalusia, Spain, pp. 239-244 in Zootaxa 5258 (2)</i> on pages 240-242, DOI: 10.11646/zootaxa.5258.2.6, <a href="http://zenodo.org/record/7777142">http://zenodo.org/record/7777142</a>

El ascenso de los judeoconversos al amparo de la alta nobleza en Castilla después de 1492: el caso de Almazán
No full textContribution to the study of the process of social assimilation of the Jews that adopted the Christian faith in the Crown of Castile after 1492, based on the analysis of a local case, that of the small town of Almazán, subject to the lordship of the counts of Monteagudo. The author pays special attention to a few families of converted Jews that attained a high social and political position, as a result of their notorious role as merchants and financiers, and of the close relationship that they kept, in the role of servants, with the counts, lords of the town.Contribución al análisis del proceso de integración social de los judíos convertidos al cristianismo en la Corona de Castilla después de 1492, a partir del estudio de un caso local concreto, el de la villa de Almazán, señorío de los condes de Monteagudo. Se centra el análisis en unas pocas familias que destacaron por su elevada posición económica, derivada de su intensa dedicación al comercio y las finanzas, y por la estrecha relación de servicio que mantuvieron con los condes, señores de la villa
La irrupción de los conversos portugueses en el comercio de exportación de lanas de la Corona de Castilla en el tránsito del siglo XVI al XVII
No full textPortuguese Conversos, many of them descendants of the Castilian Jews that were expelled in 1492, played a very important role in the export trade of the Crown of Castile during the 17th century. Among their multiple activities, the export of Castilian wool to France, the Low Countries and other European regions, was a prominent one. In this article the author contributes to the reconstruction of the first phase of the process of involvement of these merchants in this business, from the last decades of the 16th century onwards, after the merchants of Burgos abandoned it. He adopts a limited geographical perspective, because he circumscribes his analysis to a single region, that of Soria and its surroundings.Los judeoconversos portugueses, muchos de ellos descendientes de judíos castellanos expulsados en 1492, desempeñaron un destacado papel en el comercio exterior de la Corona de Castilla durante el siglo xvii. Entre sus múltiples actividades estuvo la de exportación de lana fina castellana a Francia, los Países Bajos y otros territorios europeos. En el presente trabajo el autor contribuye a la reconstrucción de la primera fase de participación de estos mercaderes en dicho negocio, a partir de las últimas décadas del siglo xvi, tras el abandono de la actividad por los mercaderes burgaleses. Y lo hace desde una perspectiva geográfica limitada, centrando el análisis en una región en concreto, la de la Tierra de Soria y su entorno

El monasterio de Santa María de Huerta entre los siglos XII y XVI: relaciones con Aragón y con los poderes nobiliarios regionales
No full textThe author traces the history of the Cistercian monastery of Santa María de Huerta, since its foundation at the beginning of the twelfth century until its admission into the Castilian Cistercian Observant Congregation at the beginning of the sixteenth century. He exposes the main effects that its location in a border region, between the kingdoms of Castile and Aragon, exercised upon its evolution during the first centuries of its history. He also pays attention to another important aspect of its medieval trajectory, the relationships that the monastic community established with the local nobility, in particular with the members of the Hinojosa lineage, until the beginning of the fourteenth century, and with the dukes of Medinaceli, since the Trastamara period. Ultimately the author tries, with the annalysis of a single case, to offer an illustration of the proccess that brought the Cistercian monasteries to lose their pan-European vocation ending up reduced to a position of second-rank actors in the social and political regional stage.El autor reconstruye la trayectoria de un monasterio cisterciense, el de Santa María de Huerta, desde su fundación a comienzos del siglo XII hasta su incorporación a la Congregación observante del Císter a principios del siglo XVI. Pone de manifiesto los efectos que tuvo para su evolución en sus primeros siglos su ubicación en una comarca fronteriza, entre los reinos de Castilla y de Aragón. Y presta también atención a otro aspecto fundamental de su trayectoria medieval, el de las relaciones establecidas por la comunidad monástica con los poderes nobiliarios, y en concreto con el linaje de los Finojosa, hasta comienzos del siglo XIV, y a partir de la época Trastámara con el de los señores de Medinaceli. En última instancia, trata de ilustrar con un ejemplo concreto, el proceso en virtud del cual los monasterios cistercienses fueron perdiendo su vocación «paneuropea» para terminar quedando reducidos a actores de segunda fila de los escenarios sociopolíticos regionales en sus respectivos reinos
