An annotated catalogue of the scorpion types held in the Zoological Museum Hamburg - Part I



Scorpions have been collected for several centuries and fortunately many collectors have deposited the specimens into museum collections. The Zoological Museum in Hamburg (ZMH) holds one of the largest and most significant scorpion collections in the world. Lionel Monod and co-workers have now published an annotated catalogue of the ZMH scorpion collections. The current paper covers the parvorder Iurida Soleglad & Fet, 2003. Especially interesting is the documentation of type specimens of 89 species, many illustrated with pictures.

Abstract:
Scorpions have always inspired fear and fascination because of the potency of their venoms. Although this ancient arachnid group is relatively small (ca. 2400 species) and has been continuously studied for the past century, the taxonomy is still in a state of flux and the correct identification of species often remains difficult. With more than 725 species and 9000 specimens, the Zoological Museum in Hamburg (ZMH) holds one of the largest and most significant scorpion collections in the world. This collection also contains many historical types described by Karl Kraepelin in the early 20th century. In order to contribute to a more stable scorpion taxonomy and to assist future scorpion researchers, we present an illustrated and annotated catalogue of the ZMH scorpion collections. The type specimens of 89 species belonging to 10 families are documented, imaged and assessed alongside their primary data. For practical reasons, only the taxa belonging to the parvorder Iurida Soleglad et Fet, 2003 are presented here whilst the Parvorder Buthida Soleglad et Fet, 2003 will be catalogued in a second publication.

A new species of Catalinia from California, USA



Riolando Teruel and Brandon Myers just published a new article with the description of a new species in the small genus Catalinia Soleglad, Ayrey, Graham & Fet, 2017 (Vaejovidae) from southern California, USA.

Catalinia ayreyi Teruel & Myers, 2019

Abstract:
Herein we describe a new species of the vaejovid scorpion genus Catalinia Soleglad, Ayrey, Graham & Fet, 2017. It was collected in a single locality of the northwestern foothills of the Santa Ana Mountains. It is most closely related to both Catalinia andreas (Gertsch & Soleglad, 1972) and C. minima (Kraepelin, 1911), but is clearly distinguished by tegumentary sculpture, morphometric ratios and pectinal tooth counts. The new species is described and illustrated in detail, with some ecological data included; moreover, a minor correction is introduced to the diagnosis of the genus.

A new vaejovid genus from USA and Mexico


Michael E. Soleglad and co-workers have recently published an article presenting a new genus in the family Vaejovidae from USA and Mexico. Four species have been included in the new genus.

Catalinia Soleglad, Ayrey, Graham & Fet, 2017 (New genus).

Catalinia andreas (Gertsch & Soleglad, 1972) (Previously Pseudouroctonus andreas (Gertsch & Soleglad, 1972)).

Catalinia castanea (Gertsch & Soleglad, 1972) (Raised from subspecies status. Previously Pseudouroctonus minimus castaneus (Gertsch & Soleglad, 1972)).

Catalinia minima (Kraepelin, 1911) (Previously Pseudouroctonus minimus minimus (Kraepelin, 1911)).

Catalinia thompsoni (Gertsch & Soleglad, 1972) (Raised from subspecies status. Previously Pseudouroctonus minimus thompsoni (Gertsch & Soleglad, 1972)).

The habitat and biogeography of the new species is discussed. An identification key is also provided.

Abstract:
Genus Catalinia, gen. nov. (Scorpiones: Vaejovidae) is described from southern California, USA and Baja California, Mexico. The genus is composed of four species formerly placed in Pseudouroctonus: Catalinia minima (Kraepelin, 1911), comb. nov. (type species), C. andreas (Gertsch et Soleglad, 1972), comb. nov., C. castanea (Gertsch et Soleglad, 1972), comb. nov., and C. thompsoni, comb. nov. (Gertsch et Soleglad, 1972). Major diagnostic characters of Catalinia include a carapace with a very weak anterior indentation, a very stout metasoma with little or no tapering from segment I to V, and a mating plug with two partial bases. Evidence is presented suggesting that Catalinia is closely related to the “apacheanus” species group of Pseudouroctonus.
