Three new species of Scorpiops from India

 

Shubhankar Deshpande and co-workers have recently described three new species of Scorpiops Peters, 1861 (Scorpiopidae) from India based on morphological and molecular analysis.

Abstract:
The scorpion genus Scorpiops Peters, 1861 exhibits significant diversity and high endemism. Our extensive arachnological surveys, species delimitation analyses and an integrative taxonomic approach revealed three new species of Scorpiops in peninsular India. Furthermore, we tested the phylogenetic placement of Scorpiops pachmarhicus Bastawade, 1992 and give the first description of a male specimen of the species. Additionally, we provide a detailed account of the hemispermatophore morphology in Scorpiops species from the maharashtraensis, satarensis, and tenuicauda clades for the first time.

A revision of the enigmatic genus Charmus from India and Sri Lanka with a couple of taxonomic updates

 

Charmus Karsch, 1879 (Buthidae) is a genus that is rarely encountered in the field and in collections. The few species in the genus are also very similar. Mihir Joshi and several co-workers have recently published a systematic review of this genus and have made a couple of taxonomic decisions.

Charmus indicus Hirst, 1915 is synonymized with Charmus laneus Karsch, 1879.

Abstract:
India and Sri Lanka are known to exhibit high levels of biological diversity with many endemic taxa, such as the enigmatic scorpion genus Charmus Karsch, 1879. Members of this genus are rarely encountered in the field and are also known to be morphologically very similar, which impedes their systematic assessment. Our dedicated efforts towards sampling the members of the genus resulted in the collection of important material, which allowed us to carry out a thorough systematic revision of the genus using an integrated taxonomic approach. We propose several taxonomic changes based on the results of a detailed morphological study supported by molecular data. Charmus indicus Hirst, 1915 is synonymized with Charmus laneus Karsch, 1879, owing to the lack of morphological differences and low genetic divergence between the two taxa. We designate a neotype for Charmus sinhagadensis Tikader and Bastawade, 1983, and describe a new species from Sirumalai (Tamil Nadu, India). Moreover, we provide the first molecular phylogeny of Charmus based on Cytochrome c Oxidase subunit I (COI), 16S rRNA (16S) and 28S rRNA (28S) genes. The phylogenetic position of the genus within the family Buthidae C. L. Koch, 1837 is also tested using an independent genome-wide dataset (Ultraconserved Elements). Topological congruence and discrepancies between the phylogenies generated with Sanger sequences and the Ultraconserved Elements are commented on, and the reliability of these datasets when evaluating phylogenetic relationships at different hierarchical levels is further discussed.
