Abstract Meruidae, or comb-clawed cascade beetles, are a recently discovered monotypic family of Adephaga endemic to Venezuela. The larvae Meruidae described for the first time, based on material Meru phyllisaeSpangler & Steiner, 2005, collected together with adults in southern External morphological features, including chaetotaxy, reported mature larva and an assessment made polarity larval characters phylogenetic utility Adephaga. Larvae possess mixture primitive derived character...

Water reservoirs formed by the leaf axils of bromeliads are a highly derived system for nutrient and water capture that also house diverse fauna invertebrate specialists. Here we investigate origin specificity bromeliad-associated insects using Copelatinae diving beetles (Dytiscidae). This group is widely distributed in small bodies throughout tropical forests, but subset species encountered bromeliad tanks strictly specialized to this habitat. An extensive molecular phylogenetic analysis...

The family Meruidae has been established recently for the newly discovered species Meru phyllisae Spangler & Steiner, 2005 from Southern Venezuela. These beetles are morphologically highly distinct and at a body length of 0.8 mm represent perhaps smallest individuals Adephaga. Here, we use DNA sequence data to place this enigmatic taxon relative other aquatic groups in suborder. was most closely associated with Noteridae, supporting previous analysis morphological structures which had...

Radicitus gen. n. is described to accommodate three new species of water scavenger beetles from the Guiana Shield region South America: R. ayacucho sp. (Venezuela), granitum and surinamensis (Suriname). The genus placed in subfamily Acidocerinae, likely shares an affinity with Helochares Mulsant its relatives. It characterized by convex body form, short maxillary palps, partially glabrous hind femora, complete fifth abdominal ventrite. All collections were made root mats debris seepages over...

Suphisellus shorti sp. n. is described from “Los Llanos”, Venezuela, which brings to six the number of species includedin Noteridae genus Crotch, 1873 recorded in this country. Specimens were collected The Plains regionin Venezuela (Apure and Guarico states) using either a light trap or net. Description illustration new speciesare provided along with discussion its systematic position. can be distinguished other spe-cies by following main characters: crease at posterolateral angle pronotum...

Recently, we described the first known larvae of enigmatic aquatic beetle family Meruidae (Alarie et al., 2011) and coded 28 larval features into a limited character matrix 12 taxa to provide phylogenetic context morphology that discussed.In our analysis, Meru was placed as sister remaining Dytiscoidea -an identical placement preceding morphological analysis by Dressler & Beutel (2010).Subsequently, incorporating newly illuminated characters, al. (2011) provided reanalysis in an expanded...

The Neotropical skiff beetle genus Yara Reichardt and Hinton is recorded from Venezuela for the first time, marking discovery of since its original description in 1976. Venezuelan species, maculata Short, Joly, Garcia, new described illustrated, bringing total number species to three. It currently known several localities along northwestern edge Guiana Shield. presence a mat recumbent setae on tergite IV, often considered diagnostic family, found be absent Yara. A key three provided as well...

In recent years, several new genera have been erected in the subfamily Copelatinae, including description of endemic taxa from Madagascar, New Guinea, South Africa, and Venezuela. Here we build upon a molecular phylogeny this to investigate phylogenetic placement Rugosus García, 2001, genus comprising two species Guiana Shield region We sequenced one mitochondrial nuclear gene fragment emarginatus as well specimen Aglymbus leprieurii Aubé Guyana order reassess Copelatinae.

Este trabajo tiene como propósito la evaluación del extracto de “lulo perro”, en calidad limpiador sanitizante biodegradable, para contribuir a e inocuidad industria alimentaria y reducir el impacto negativo hacia medio ambiente. El proyecto se realizó conmaterial biológico recolectado quincenalmente durante tres meses corredor universitario ciudad Tunja. La extracción saponinas llevó cabo siguiendo proceder M. E. Wall 1958. Se realizaron ensayos químicos cualitativos concentración...

En dos sistemas hidroecológicos de origen antropogénico (lagunas estabilización-oxidación), ubicados en el nororiente y noroccidente Venezuela, se realizó un estudio faunístico para identificar las especies insectos acuáticos que habitan ambientes artificiales altamente contaminados. La recolección los ejemplares efectúo utilizando métodos capturas cinco microhábitats anpogeno del sistema conocidos como spaqua, supaqua, hercircum, caenum petra, lográndose registro 54 pertenecientes a cuatro...

Se reevaluaron las especies de Andonectes Guéorguiev depositadas en la colección del Museo Artrópodos La Universidad Zulia (Maracaibo, Venezuela), y se consideró que los caracteres taxonómicos atribuidos previamente no coincidían con actual definición género, pero si calzan Platynectes Régimbart, subgénero Agametrus Sharp. A partir esto, establecen doce nuevas combinaciones taxonómicas: (Agametrus) apure (García), P. bordoni gregarius intermedius meridensis mildredae milla pineiroi...
