Hexanchorus bifurcatus sp. nov., a new tepui riffle beetle (Coleoptera: Elmidae: Larainae) from Tafelberg, Suriname. - Zootaxa
Here we present the first published record of a laraine elmid from Suriname, which represents a new species - Hexanchorus bifurcatus sp. nov. Specimens were collected from the summit of Tafelberg, a table mountain near the Wilhelmina Range of Suriname. This species can be distinguished from all other Hexanchorus by the bifurcate elytral apices and median projection of the third abdominal ventrite of the female, as well as the distinctive male genitalia. Habitus photos, illustrations of the genitalia, a distribution map, notes on habitat, and comparative diagnoses are provided. 
Review of the Lutrochidae (Coleoptera) of the Guianas and Lesser Antilles, with description of four new species. - Zootaxa
The species of Lutrochidae from the Guianas, and the Lesser Antilles are reviewed, including the first reports of the family from Guyana, Suriname, and Grenada. Four species are described as new: Lutrochus funkae n. sp. and L. wao n. sp. from Guyana and French Guiana, L. grenadensis n. sp. from Grenada, and L. leeanneae n. sp. from Suriname. Photographs, genitalia illustrations, and distribution maps are provided for all species, and habitat photos and notes are presented for the species for which they are available.
A new genus of egg case-carrying water scavenger beetle from the Guiana Shield (Coleoptera: Hydrophilidae: Acidocerinae). - Zootaxa
Radicitus gen. n. is described to accommodate three new species of water scavenger beetles from the Guiana Shield region of South America: R. ayacucho sp. n. (Venezuela), R. granitum sp. n. (Venezuela), and R. surinamensis sp. n. (Suriname). The genus is placed in the subfamily Acidocerinae, and likely shares an affinity with the genus Helochares Mulsant and its relatives. It is characterized by its convex body form, short maxillary palps, partially glabrous hind femora, and complete fifth abdominal ventrite. All collections of the new genus were made from root mats and debris from seepages over rock outcrops or, rarely, root mats from streams. Individual females of all three species were observed to adhere their egg case to the venter of the abdomen.
Clade age and diversification rate variation explain disparity in species richness among water scavenger beetle (Hydrophilidae) lineages. - PloS one
Explaining the disparity of species richness across the tree of life is one of the great challenges in evolutionary biology. Some lineages are exceptionally species rich, while others are relatively species poor. One explanation for heterogeneity among clade richness is that older clades are more species rich because they have had more time to accrue diversity than younger clades. Alternatively, disparity in species richness may be due to among-lineage diversification rate variation. Here we investigate diversification in water scavenger beetles (Hydrophilidae), which vary in species richness among major lineages by as much as 20 fold. Using a time-calibrated phylogeny and comparative methods, we test for a relationship between clade age and species richness and for shifts in diversification rate in hydrophilids. We detected a single diversification rate increase in Megasternini, a relatively young and species rich clade whose diversity might be explained by the stunning diversity of ecological niches occupied by this clade. We find that Amphiopini, an old clade, is significantly more species poor than expected, possibly due to its restricted geographic range. The remaining lineages show a correlation between species richness and clade age, suggesting that both clade age and variation in diversification rates explain the disparity in species richness in hydrophilids. We find little evidence that transitions between aquatic, semiaquatic, and terrestrial habitats are linked to shifts in diversification rates.
Ciimaerocyon gen. nov., a morphologically aberrant myrmecophilous genus of water scavenger beetle (Coleoptera: Hydrophilidae: Sphaeridiinae). - Zootaxa
Anew hydrophilid genus Chimaerocyon gen. nov. containing two species, C. shimadai sp. nov. (Malaysia: Pahang) and C. sumatranus sp. nov. (Indonesia: Sumatra), is described. Specimens of C. shimadai were collected from brood cells in anest of Pheidole singaporensis Özdikmen, 2010. The biology of C. sumatranus remains unknown. A molecular phylogeny based on four genes (cox1, cox2, 18S and 28S) supports the placement of the genus as deeply nested within the Cercyon-group of the tribe Megasternini. This position is supported by the subdistal position of the median spur in the hind wing (unique to Megasternini) and the presence of sucking disc on male maxilla (unique for Megastemini+Sphaeridiini). The remaining external morphology differs substantially from other representatives of Megasternini. The hypothesis that the aberrant morphology of Chimaerocyon gen. nov. is a consequence of myrmecophily is discussed.
A revision of the Lutrochidae (Coleoptera) of Venezuela, with description of six new species. - Zootaxa
The species of Lutrochidae occurring in Venezuela are revised. The only previously recorded species, Lutrochus acuminatus Grouvelle, is redescribed and a lectotype is designated. Lutrochus vestitus Sharp, is recorded from Venezuela and French Guiana for the first time. Six new species Lutrochus gustafsoni n. sp., L. cauraensis n. sp., L. maldonadoi n. sp., L. meridaensis n. sp., L. minutus n. sp., and L. violaceus n. sp. are described. Notes on habitat and habits for most species are provided, as well as a key to the eight species of Lutrochidae occurring in Venezuela. The family is reported from hygropetric habitats for the first time.
New species and new records of the hygropetric water beetle genus Oocyclus Sharp from South America (Coleoptera: Hydrophilidae). - Zootaxa
Three new species of Oocyclus Sharp, 1882 are described from tropical South America: O. maluz sp. n. (Venezuela), O. miza sp. n. (Venezuela), and O. brunneus sp. n. (Bolivia). New distributional records are provided for O. andinus Short & García, O. coromoto Short & García (newly recorded from Suriname), O. floccus Short & García (newly recorded from Guyana and Suriname), O. iguazu (Oliva), O. meridensis Short & García, O. petra Short & García (newly recorded from Guyana and Suriname), O. trio Short & Kadosoe (newly recorded from Guyana), O. trujillo Short & García, and O. yubai Clarkson & Short (newly recorded from Paraguay). Updates to the keys of the Brazilian and Venezuelan Oocyclus species are provided.
Review of the Berosus Leach of Venezuela (Coleoptera, Hydrophilidae, Berosini) with description of fourteen new species. - ZooKeys
The species of the water scavenger beetle genus Berosus Leach occurring in Venezuela are reviewed. Thirty-six species are recorded, including fifteen new species, fourteen of which are described here as new: Berosus araguasp. n., Berosus asymmetricussp. n., Berosus capanaparosp. n., Berosus castaneussp. n., Berosus corozosp. n., Berosus ebeninussp. n., Berosus garciaisp. n., Berosus humeralissp. n., Berosus jolyisp. n., Berosus llanensissp. n., Berosus megaphallussp. n., Berosus ornaticollissp. n., Berosus repertussp. n., and Berosus tramidrumsp. n. The fifteenth new species, known from a single female, is left undescribed pending the collection of males. Twelve species are recorded from Venezuela for the first time: Berosus ambogynus Mouchamps, Berosus consobrinus Knisch, Berosus elegans Knisch, Berosus geayi d'Orchymont, Berosus ghanicus d'Orchymont, Berosus guyanensis Queney, Berosus holdhausi Knisch, Berosus marquardti Knisch, Berosus olivae Queney, Berosus reticulatus Knisch, Berosus wintersteineri Knisch, and Berosus zimmermanni Knisch.
Discovery of the water scavenger beetle genus Brownephilus Mouchamps in Turkey (Coleoptera, Hydrophilidae, Hydrophilini. - ZooKeys
The recently described Hydrochara major Ä°ncekara, Mart, Polat, & Karaca, 2009 from Turkey is transferred to the genus Brownephilus Mouchamps. New records and habitat information are given for the species, as well as diagnostic features for separating it from the only other described member of the genus, Brownephilus levantinus Balfour-Browne. The discovery of Brownephilus in Turkey marks the first time the lineage has been found since its original description more than seventy years ago.
Congenital hypopituitarism associated with hyperammonemia. - Indian journal of pediatrics
Neonatal onset hypopituitarism is a life threatening but potentially treatable metabolic condition. However, in the majority of cases it can be fatal due to the metabolic disturbances. We report a newborn with profound symptomatic hypoglycemia and hyperammonemia who initially was thought to have an inborn error of metabolism (IEM). After an initial falsely reassuring magnetic resonance imaging (MRI) brain scan, further endocrine investigation eventually led to the correct diagnosis and treatment.
