The genus Brachistosternus (Scorpiones: Bothriuridae) in Chile, with Descriptions of Two New Species

Two new scorpion species from Paposo, in the coastal desert of Taltal, Chile (Scorpiones, Bothriuridae, Brachistosternus).

Brachistosternus paposo n. sp. and Brachistosternus barrigai n. sp. are described from Paposo, in the coastal transitional desert of northern Chile. Brachistosternus paposo n. sp. is closely related to Brachistosternus roigalsinai Ojanguren-Affilastro 2002, and B. barrigai n. sp. is closely related with Brachistosternus kamanchaca Ojanguren-Affilastro, Mattoni & Prendini 2007.

New Analysis of the Genus Pseudouroctonus with the Description of Two New Species (Scorpiones: Vaejovidae)

Systematics and biology of the new genus Macrosaccus with descriptions of two new species (Lepidoptera, Gracillariidae)

The new genus Macrosaccus Davis & De Prins is proposed for three species formerly assigned to the genus Phyllonorycter: Macrosaccus robiniella (Clemens), Macrosaccus morrisella (Fitch), and Macrosaccus uhlerella (Fitch); two new, closely related species: Macrosaccus neomexicanus Davis and Macrosaccus gliricidius Davis, are also proposed. Descriptions of the adults, pupae, larvae, life histories...

The Genus Polystenus (Hymenoptera: Braconidae: Doryctinae) in China, with Descriptions of Two New Species

The species of Polystenus Foerster, 1862 (Hymenoptera: Braconidae: Doryctinae) from China are revised, and four species are recognized. Two new species, P. brevitergum sp nov. and P. taiwanus sp nov., are described and illustrated. A key to all species of the genus Polystenus is provided.

A comparative cytogenetic analysis of 2 Bothriuridae species and overview of the chromosome data of Scorpiones.

The order Scorpiones is one of the most cytogenetically interesting groups within Arachnida by virtue of the combination of chromosome singularities found in the 59 species analyzed so far. In this work, mitotic and meiotic chromosomes of 2 species of the family Bothriuridae were detailed. This family occupies a basal position within the superfamily Scorpionoidea. Furthermore, review of the cyt...
