Geckos of the genus are widely distributed in the sand deserts of the Arabian Peninsula. Three species of this genus are currently recognized, with a fourth one, , which placement within has been tentatively suggested, but not yet confirmed. We present a phylogenetic analysis of the genus with new specimens collected in central Saudi Arabia and southern Jordan. New genetic data has been generated from three mitochondrial markers to investigate the phylogenetic relationships of all species of the genus and to assess the putative generic assignment of . Our results confirm that indeed belongs within , branching as a sister lineage to all other species of the genus. The new samples cluster within , thus confirming the genetic homogeneity of the species across its large and seemingly inhospitable range. The new specimen collected in southern Jordan represents the first record for the country and a considerable range extension to the northwest from all previously reported localities. Our findings and discovery of a new species for Jordan highlight the need of more field surveys to be carried out in the underexplored parts of Jordan and northern Saudi Arabia, as these places still hold a potential for new discoveries and are crucial for understating the biogeography of the Arabian herpetofauna.

The small-sized cervid Procervulus is considered as the most basal member of the Cervidae and one of the earliest ruminants bearing antler-like appendages. The Iberian Miocene record of this stem-cervid is extensively documented and largely overlaps with the Miocene Climatic Optimum (MCO), a transient period of global warming of particular interest when comparing present and near future conditions. Despite receiving a substantial amount of attention, histological studies on Procervulus are very scarce and only limited to postcranial remains of Procervulus praelucidus from Germany (MN3).

The Indian subcontinent has emerged as a natural habitat to several cyanobacterial taxa which have been explored and described in the past few years using a polyphasic approach. Various new genera and species of Nostoc morphotypes, heteropolar unbranched as well as branched heterocytous cyanobacteria, have been described from various parts of India such as the central mainland, temperate hill stations of extreme northern India, and the biodiversity hotspots of northeast India. Konkan, a small strip of land bounded by Arabian sea on the west and Sahyadri mountains on the east, has various habitats such as coastal beds, old monuments, freshwater lakes, and rivers; however, this region has been less charted in modern cyanobacterial systematics, relative to others.

Introduction: Nonhuman primates (NHPs) can transmit zoonotic diseases to humans because of their close genetic relationship, facilitating the cross-species transmission of certain pathogens. In Thailand, Macaca is the most common NHP genus and their inhabits area are in close proximity of human, particularly in urban and suburban areas, where frequent interactions with humans increase the risk of pathogen transmission. The risk is influenced by factors such as the type of pathogen, the mode of transmission (e.

Background: Freshwater fish are affected with much parasitic diseases, among the most common are Henneguyosis caused by myxozoans of the genus Henneguya, which exhibit great diversity in fish from South America, particularly in the Brazilian Amazon.
Purpose: In this present study, we describe the morphological and phylogenetic aspects of the small ribosomal subunit (SSU rDNA) of two new species of Henneguya infecting the gills from Hypophthalmus marginatus, a freshwater catfish from the Amazon.
Methods: In 148 specimens, has been observed cyst formation in different regions of the gills, intrafilamentary and intralamellar.

Purpose: Fish are susceptible to various parasitic infections, with Myxozoa emerging as a major group. A taxonomic study of Myxozoa is essential for the rapid diagnosis of species potentially responsible for epizootic diseases.
Methods: The studied fish was collected from the Kadey River, a tributary of the Sangha River in the Congo Basin in Cameroon, and parasitologically dissected.
