In Colombia, detailed knowledge of the geographic distribution of gymnophthalmid lizards is scarce. This paper presents the first confirmed records of Leposoma rugiceps and provides additional records of Gymnophthalmus speciosus from Department of La Guajira, in the Colombian Caribbean Region. These records extend the geographical distribution of both species and support their wide distribution in the lowlands of north of Colombia. Furthermore, we provide an updated distribution map with known occurrences of these species in Colombia.

<p>Remnants of the Caribbean Large Igneous Plateau (C-LIP) are found as thickened zones of oceanic crust in the Caribbean Sea, that formed during strong pulses of magmatic activity around 90 Ma. Previous studies have proposed the Galápagos hotspot as the origin of the thermal anomaly responsible for the development of this igneous province. Particularly, geochemical signature relates accreted C-LIP fragments along northern South America with the well-known hotspot material.</p><p>In this research, we use 3D lithospheric-scale structural and density models of the Caribbean region, in which up-to-date geophysical datasets (i.e.: tomographic data, Moho depths, sedimentary thickness, and bathymetry) have been integrated. Based on the gravity residuals (modelled minus observed EIGEN6C-4 dataset), we reconstruct density heterogeneities both in the crust and the uppermost oceanic mantle (< 50km).</p><p>Our results suggest the presence of two positive mantle density anomalies in the Colombian and the Venezuelan basins, interpreted as the preserved plume material which migrated together with the Proto-Caribbean plate from the east Pacific. Such bodies have never been identified before, but a positive density trend is also observed in the mantle tomography, at least down to 75 km depth.</p><p>Using recently published regional plate kinematic models and absolute reference frames, we test the hypothesis of the C-LIP origin in the Galápagos hotspot. However, misfits of up to ~3000 km between the present hotspot location and the mantle anomalies, reconstructed back to 90 Ma, is observed, as other authors reported in the past.</p><p>Therefore, we discuss possible sources of error responsible for this offset and pose two possible interpretations: 1. The Galápagos hotspot migrated (~1200-3000 km) westward while the Proto-Caribbean moved to the northeast, or 2. The C-LIP was formed by a different plume, which – if considered fixed - would be nowadays located below the South American continent.</p>

Acanthonus armatus Günther, 1878 is reported for the first time in the southwestern Caribbean region, off Colombia. Remote Operate Vehicle videos and towed camera still photographs captured 13 images of A. armatus between 2215 and 2564 m. These are the first records of the species in the Caribbean continental coast of Colombia, representing a range extension to the southwestern Caribbean region, since previous records are from the northeastern Caribbean. Some photos of the specimens and the current distribution of the species in the Caribbean region are provided and reviewed.

We describe a new genus and species of remipede crustacean from an anchialine cave on the Turks and Caicos Islands in the Caribbean region. Kaloketos pilosus is a medium-sized species of robust build that occurs in sympatry with other remipedes, and is recognized as a new genus of the family Speleonectidae. Kaloketos is distinguished from other genera of Remipedia by several unique characters that include dense fields of short, feathered setae on most maxillary and maxillipedal segments, and distinctly expanded rami of the larger trunk limbs.

Two new species of Brazilian Psychoda Latreille are described, and Psychoda alternata Say and P. zetoscota Quate are recorded for the first time from Brazil. Psychoda divaricata Duckhouse, already described from southern Brazil, was recorded in the northeastern part of that country, as well as in the eastern Amazon region. The supraspecific classification proposed for the species of Psychoda according to Quate (= Psychodini of Jeñek) are discussed. A new classification is suggested that considers only one genus, Psychoda, divided into 12 subgenera: subgenus Psychoda Latreille, subgenus Copropsychoda Vaillant, subgenus Falsologima Jeñek & Harten, subgenus Psychodula Jeñek, subgenus Psychomora Jeñek, subgenus Psychana Jeñek & Harten, subgenus Logima Eaton, subgenus Tinearia Schellenberg, subgenus Chodopsycha Jeñek, subgenus Ypsydocha Jeñek, subgenus Psychodocha Jeñek, and subgenus Psycha Jeñek. A list of the Psychoda species from Latin America and the Caribbean region is presented.

Our data show that this species has a wide geographical distribution, including the Pacific versant of the Cordillera Occidental, the inter-Andean valley of the Magdalena River, and the Caribbean lowlands of northern Colombia.

The rarely reported Asioplax dolani (Allen) is newly documented from the Austroriparian ecological region of Texas. Leptohyphes zalope Traver, known from the southwestern United States and much of Central America, is newly documented from the Caribbean Islands of Grenada and Tobago. This represents only the second leptohyphid mayfly known from both Continental America and the Caribbean region. Additional Caribbean records of Allenhyphes flinti (Allen) are also given.

While earlier works have shown that the operculum is inserted in the position of the first or second branchial radiole in serpulimorph taxa, the present paper shows that it is inserted independently of the branchial radioles of both sides in the genera Galeolaria and Pyrgopolon. Although both genera possess several characters in common with the group consisting of Pomatoleios, Pomatoceros and Spirobranchus, a cladistic analysis revealed that they form two distinct clades, as sister groups to each other. Extant species of Pyrgopolon occur mainly in the Caribbean region, and of Galeolaria in eastern Australia and New Zealand. However, there is palaeontological evidence indicating that fossil species of Pyrgopolon had a wider geographical distribution, having existed in Europe during geological times.

Colombia is a mega-biodiverse country and rich in ecosystems as different as the Amazon and the Andes. Much is known of the vertebrate fauna, however there is still an information-gap for many arthropod groups including the arachnids. Here, we compile all the information available for pseudoscorpions (Arachnida: Pseudoscorpiones) recorded from Colombia and include several new records and distribution extensions. For each described species, we present information on taxonomic history, type localities, global and local distributions, repository of Colombian specimens, and collection numbers when available. We document 12 families, 45 genera and 65 species of pseudoscorpions for Colombia and most species belong to the families Chernetidae (27 species) and Olpiidae (8 species). We record Beierolpium venezuelense Heurtault, 1982, Geogarypus amazonicus Mahnert, 1979, Sathrochthonius venezuelanus Muchmore, 1989, and Semeiochernes armiger (Balzan, 1892) for the first time for Colombia. We further extend the known ranges of Parachernes melonopygus Beier, 1959 and Paratemnoides nidificator (Balzan, 1888). The data suggest that the Caribbean region of Colombia has the highest number of records. Total numbers are not complete and many other new pseudoscorpion species are expected.
