A checklist of the scorpion fauna of Vietnam


Dinh-Sac Pham and co-workers have recently published an updated checklist of the scorpion fauna of Vietnam.

Abstract:
A faunistic inventory is proposed for the known Vietnamese scorpion species. The aim of this contribution is to bring an up-to-date checklist of all known species in Vietnam, prior to a more detailed study of the Vietnamese fauna to be performed by one of the authors (T.- H.T.) in the context of the preparation of a doctoral degree. Final taxonomic decisions should be taken at the end of the doctoral dissertation.

An update on the genus Tityus in Hispaniola, Greater Antilles


Rolando Teruel has been able to investigate types and additional materials of Tityus C. L. Koch, 1836 from Hispaniola, Greater Antilles. The investigation showed that many of the species are highly variable morphologically, that adults belonging to different size-classes can be easily mistaken as distinct species. Because of this, several species have wrongly been given species status.The paper's conclusions are:

Tityus anasilviae Armas & Abud, 2004 is synonymized with Tityus ottenwalderi Armas, 1999.

Tityus bahoruco Teruel & Armas, 2006 is synonymized with Tityus crassimanus (Thorell, 1876).

Tityus ebanoverde Armas, 1999 is synonymized with Tityus elii Armas & Marcano, 1992.

Tityus septentrionalis Armas & Abud, 2004 is synonymized with Tityus portoplatensis Armas & Marcano, 1992.

In addition, the following fossil taxa are synonymized:

Tityus azari Lourenço, 2013 and Tityus (Brazilotityus) hartkorni Lourenço, 2009 are both synonymized with Tityus geratus Santiago-Blay & Poinar, 1988.

Abstract:
In the present paper, the taxonomic status of several Hispaniolan members of the genus Tityus C. L. Koch, 1966 is revised after examination of almost all primary types and abundant supplementary material. This resulted in six new synonymies, which involve both extant and fossil species. The extant taxa herein synonymized are Tityus anasilviae Armas et Abud, 2004 under Tityus ottenwalderi Armas, 1999, Tityus bahoruco Teruel et Armas, 2006 under Tityus crassimanus (Thorell, 1876), Tityus ebanoverde Armas, 1999 under Tityus elii Armas et Marcano, 1992, and Tityus septentrionalis Armas et Abud, 2004 under Tityus portoplatensis Armas et Marcano, 1992. The fossil taxa herein synonymized are Tityus azari Lourenço, 2013† and Tityus (Brazilotityus) hartkorni Lourenço, 2009†, both under Tityus geratus Santiago-Blay et Poinar, 1988†. Updated distribution maps are given for all extant senior synonyms.

Dangerous scorpions in Mexico and how to identify them


In the end of 2016, Javier Ponce-Saavedra and co-workers published a paper on scorpions of medical importance in Mexico. Mexico has many dangerous species, and the paper has an identification guide for species of medical importance, partly illustrated with good quality pictures. Data on distribution within Mexico is also presented. The paper also has epidemiological data for serious scorpion incidents from 1997 to 2015.

The article is in Spanish.

Abstract:
Scorpionism is one of the most important public health issues in Mexico. Intoxication by scorpion sting is in the first place among illnesses by poisonous animals and it is among the top twenty causes of mortality in the country, and in some states it is even among the top ten. An analysis of morbidity for the laps 2006-2015, and mortality during 1997-2013, by scorpion sting, is presented using data from Mexican health authorities. For each state the responsible scorpion species are reviewed, along with morbidity and mortality records. An identification key for species of medical importance in Mexico is included.

A new species of Grosphus from Madagascar


Wilson Lourenco and co-workers have recently described a new species of Grosphus Simon, 1880 from northern Madagascar.

Grosphus ganzhorni Lourenco, Wilme & Waeber, 2016

Abstract:
A new species, associated with Grosphus annulatus Fage, 1929, is described from the Akarana Massif in the north of Madagascar. Some comments on biogeographical aspects linking the new species with its possible vicariant are also included.

A new species of Opisthacanthus from South-East Madagascar


Wilson Lourenco and co-workers have investigated new hormurid materials from Madagascar and a new species of Opisthacanthus Peters, 1861 (Hormuridae) has been described from the Lavasoa forest in south-eastern Madagascar..

Opisthacanthus lavasoa Lourenco, Wilme & Waeber, 2016

The geographic distribution, biogeography and ecology of the Malagasy species of Opisthacanthus  is also discussed.

Abstract:
A new species, Opisthacanthus lavasoa sp. n., is described from the Lavasoa Forest, in south-eastern Madagascar. The new species shows affinities with both Opisthacanthus madagascarensis Kraepelin, 1894, known from the western portion of the island, and Opisthacanthus ambanja Lourenco, 2014, known only from the extreme north of the island. The new species and O. madagascarensis have similar external morphologies, whereas with O. ambanja the new species shares a similar morphology of the hemispermathophores. Moreover, O. madagascarensis is exclusively found in spiny forest thickets and svannah-like formations, whereas the new species was found in a humid forest. The total number of species in Madagascar is now raised to eleven.

The true taxonomic identity of Centruroides tenuis from Hispaniola, Greater Antilles


The title is "stolen" from a recent paper by Rolando Teruel. In this, paper the taxonomic status of Centruroides tenuis Thorell, 1876 and Centruroides zayasi Armas, 1976 from the Caribbean is investigated. The conclusion is that C. tenuis is a valid species and that C. zayasi is a junior synonym of the former.

Abstract:
The precise taxonomic identity of two taxa, Centruroides tenuis (Thorell, 1876) and Centruroides zayasi Armas, 1976, which has been the subject of prolonged controversy, is finally clarified. The study of three syntypes of the first taxon and the holotype of the second taxon has revealed that the syntypes correspond to two species which are the second taxon’s potential junior synonyms, Centruroides marcanoi Armas, 1981 and C. zayasi. One of the syntypes, the best preserved female adult, is here designated as the lectotype of C. tenuis. Consequently, the following nomenclatural change is proposed: Centrurus tenuis Thorell, 1876 = Centruroides zayasi Armas, 1976, syn. nov.

Centruroides platnicki discovered in Hispaniola, Greater Antilles


Teruel & Seiter have recently reported about the discovery of the buthid Centruroides platnicki Armas 1981 (Buthidae) in the Caribbean island of Hispaniola. C. platnicki has probably been collected from the island in the past, but have been misidentified as Centruroides nitidus (Thorell, 1876).

Abstract:
The Buthid scorpion Centruroides platnicki Armas 1981 is recorded for the first time from the Caribbean island of Hispaniola. The species was so far known only from the southern Bahamas (including the Turks and Caicos Islands). Numerous adult and juvenile specimens of both sexes were found at two localities of Montecristi province (north-western Dominican Republic), always in desert vegetation on alluvial clayey soils.
