RESUMO

The spider subfamily Spartaeinae Wanless, with its only New World tribe Lapsiini (Araneae: Salticidae) is for the first time recorded from Colombia. Six new species of the genera Lapsias Simon and Thrandina Maddison are described and illustrated herein from the country. From the Andean region are described: L. iguaque sp. nov. (; Boyac department), Lapsias quimbaya sp. nov. (; Quindo, Risaralda, and Caldas departments), L. tequendama sp. nov. (; Cundinamarca department), L. walekeru sp. nov. (; La Guajira department), and Thrandina colombiaenpaz sp. nov. (; Huila department). From the Sierra Nevada de Santa Marta, Magdalena department, Caribbean region, is described L. tayrona sp. nov. (). In addition, new records of Galianora sacha Maddison and L. lorax Maddison for the country are presented, and the female of L. lorax is described for the first time. Finally, a map with plotted distribution of the tribe Lapsiini from South America is presented.

RESUMO

Here we examine the species of the Selenops isopodus species group: S. isopodus Mello-Leitão, 1941, S. arikok Crews, 2011, and S. curazao Alayón, 2001. We describe the female and male of S. bullerengue sp. nov. from Colombia and synonymize S. marilus Corronca, 1998a with S. isopodus, providing diagnoses and complete descriptions of both sexes of S. isopodus. Detailed images and a key to species in the group are provided. The distribution of all selenopid species in Colombia is reviewed using published records, museum specimens, and citizen science data from inaturalist.org.

RESUMO

Brescovit (1993), in the revision of the genus Hibana, described H. talmina, based on males from Venezuela, Colombia, Guyana and northern Brazil. Subsequently, Brescovit Lise (1993) described its female, in an attempt to associate with the male, based on specimens collected in Dominica and Trinidad. Unfortunately, there was no justification for this mating. Recently Galvis et al. (2019) collected several couples of Hibana talmina in mangrove forests in some surrounding areas of Cartagena (Bolívar, Colombia), during a study of predation of crabs on these spiders. The detailed study of these couples showed that there was a wrong mating by Brescovit Lise (1993) and this is corrected here. The original distribution is updated, with the exclusion of Dominica. The females previously assigned to H. talmina are treated here as Hibana labonita sp. nov., which is diagnosed in relation to the other species of Hibana.

RESUMO

The family of mygalomorph spiders Paratropididae Simon, 1889 is here reported for the first time for Colombia, where it is represented by three genera (Anisaspis, Paratropis, Stormtropis gen. n.) and eight species. One genus, Stormtropis, and six species constitute new taxa that are here diagnosed, described and illustrated. The geographical distribution of Paratropispapilligera FO Pickard-Cambridge, 1896 and Paratropiselicioi Dupérré, 2015 are also redescribed and expanded on the basis of new material examined. The diagnosis of the subfamily Paratropidinae, Paratropis Simon, 1889 and Anisaspis Simon, 1892 are emended including the variations of the new species. Likewise, a geographic distribution map for the entire family and a taxonomic key for the males of Paratropidinae are included. Other biogeographic, morphological, and taxonomic aspects are discussed.

RESUMO

The huntsman spider genus Anaptomecus was proposed by Simon (1903) to include the type species, A. longiventris Simon, 1903, described from a juvenile male collected in Cayambé (San Pedro de Cayambé), Pichincha, Ecuador. Mello-Leitão (1940) described a second species, A. rufescens, from a female collected in Essequibo River, Guyana. The genus remained unstudied until the early 2000's when Jäger et al. (2009) described the adult male and female of A. longiventris and transferred A. rufescens to Sparianthina Banks, 1929. In this same paper, the authors described A. temii Jäger, Rheims Labarque, 2009, based on a male from Panama, and A. levyi Jäger, Rheims Labarque, 2009, based on a female from Colombia. A few years later, Guala et al. (2012), increased the number of known species with the descriptions of A. paru Guala, Labarque Rheims, 2012 and A. suni Guala, Labarque Rheims, 2012, both based on males and females from Ecuador. Thus, Anaptomecus currently includes five species and is distributed in southern Central and northern South America, from Costa Rica to central Ecuador (Puerto Napo, Napo) (World Spider Catalog 2018).

RESUMO

A new monotypic Theraphosidae genus, Kankuamo Perafán, Galvis & Pérez-Miles, gen. n., is described from Colombia, with a new type of urticating setae. These setae differ from others principally by having a small distal oval patch of lanceolate reversed barbs. Males of Kankuamo gen. n. additionally differ by having a palpal bulb organ very divergent from all known species, with many conspicuous keels dispersed across the median tegulum to the tip, mostly with serrated edges. Females differ by having spermathecae with a single notched receptacle, with two granulated lobes and several irregular sclerotized longitudinal striations. The new urticating setae, type VII, is characterized, illustrated and its releasing mechanism is discussed. It is hypothesized that these setae are the first in Theraphosinae subfamily whose release mechanism is by direct contact. Kankuamo gen. n. is described and illustrated on the basis of the type species Kankuamo marquezi Perafán, Galvis & Gutiérrez, sp. n., and their remarkable characteristics, morphological affinities and cladistic relationship are analyzed.

RESUMO

Objetivo: Determinar la prevalencia de los patrones geométricos del ventrículo izquierdo (VI) en una población de hipertensos tratados y su asociación con factores como la edad, sexo, índice de masa corporal (IMC), control de la hipertensión arterial (HTA) y clase de tratamiento recibido. Métodos: Estudio observacional, analítico y transversal. Incluyó 157 pacientes con HTA esencial tratada, los cuales se clasificaron en controlados y no controlados. Se les determinó la masa y el espesor relativo de pared (ERP) del ventrículo izquierdo (VI) mediante ecocardiografía 2D, con lo que se obtuvieron los patrones geométricos: normal, remodelado, hipertrofia concéntrica e hipertrofia excéntrica. Resultados: La prevalencia de geometría anormal del VI en los hipertensos tratados fue del 84%, la hipertrofia concéntrica fue el patrón más prevalente (47%), seguido del remodelado (22,9%) y de la hipertrofia excéntrica (14%). No hubo diferencias significativas entre los patrones geométricos en relación con edad, sexo, nivel de presión arterial (PA) e IMC, pero en la geometría anormal hubo una tendencia a un mayor valor de estos parámetros (excepto el sexo) en relación con la geometría normal. Los hipertensos no controlados en comparación con los controlados, tuvieron mayor prevalencia de geometría anormal (61,7%, vs 38,3%; p

Objective: Assess the prevalence of the geometric patterns of the left ventricle (LV) in a population of treated hypertensive patients, and its association with risk factors such as age, gender, body mass index (BMI), control of the arterial hypertension (AHP) and class of treatment received. Methods: Observational, analytic and cross sectional study. It included 157 hypertensive patients which were receiving treatment, and were classified into controlled and non-controlled. An echo 2D was performed which showed the measure of mass and relative thickness of the posterior wall (RTW) of LV. Four types of geometric patterns were found: normal, remodeled, concentric hypertrophic and eccentric hypertrophy. Results: The prevalence of abnormal LV geometry in treated hypertensive patients was 84%, the concentric hypertrophy pattern was the most prevalent (47%), followed by remodeling (22.9%) and eccentric hypertrophy (14%). There were no significant differences between the geometric patterns in relation to age, sex, level of blood pressure (BP) and BMI, but in abnormal geometry there was a trend towards a higher value of these parameters (except sex) in relation to the normal geometry. Uncontrolled compared with controlled hypertensive patients had a higher prevalence of abnormal geometry (61.7% vs 38.3%; p <0.01, OR: 3.21 [1.28-8.05]), the concentric hypertrophy pattern was associated with poor control of hypertension (p <0.032). There was no association between the type of antihypertensive and geometric pattern between groups. Conclusion: The treated essential hypertension is associated with high prevalence of abnormal LV geometry, which was not associated with age, sex, level of BP and BMI. Achieving control of hypertension showed benefit as reduced the prevalence of abnormal geometry compared with uncontrolled hypertension. The class of antihypertensive was not associated with this effect.
