In order to establish an updated checklist of terrestrial gastropod from Tunisia, a revision of the species of Sphincterochilidae is presented, using bibliographic and museum records and the results of our own field work. As a result, only two species, Sphincterochila candidissima and Sphincterochila tunetana, are accepted to occur in Tunisia, and their type specimens are illustrated. The study...
The mature larvae of the rove beetles (Coleoptera: Staphylinidae) Lathrobium lineatocolle Scriba and Tetartopeus quadratus (Paykull) are described for the first time, and the larva of Paederus littoralis Gravenhorst is redescribed. Detailed illustrations of their structural features are provided. The description of T. quadratus is the first for that genus. Diagnostic larval, morphological chara...
A review of previously published cladistic analyses of Polistes is presented. The two most recent analyses of Polistes are shown to be largely consistent phylogenetically. Although the taxonomy implied by each differs, this difference is shown to be mostly due to taxon sampling. After the review, a phylogenetic analysis of Polistes — the most data-rich yet undertaken — is presented. The analysi...
We examined the genera Tibiodrepanus Krikken, 2009 (four Oriental and one Palaearctic species) and Sulcodrepanus Krikken, 2009 (one Afrotropical species), using type specimens and non-type specimens, in order to assess the systematic consistency of the two taxa. Within this framework, we also considered the genera Afrodrepanus Krikken, 2009 (two species) and Drepanocerus Kirby, 1828 (two specie...
DNA from 14 Pythium species, Verrucalvus flavofaciens and Zoophagus insidians was characterized by CsCl-bisbenzimide density gradients in order to investigate its taxonomic potential. A few incomplete analyses were made for other species. All clearly assignable Pythium species produced three DNA bands in the gradient. Pythium undulatum along with Verrucalvus and Zoophagus produced only two band...
As a component of a larger study of the West Indian Matelea subgenus Ptycanthera, this study sought to critically examine patterns of morphological variation within the embedded M. bayatensiscorrellii-tigrina complex. Resolution of species-level circumscriptions are necessary before larger issues of subgeneric and generic circumscription can be adequately addressed. Morphological characters wer...
The family Coreidae is composed of some the larger terrestrial Heteroptera, with showy colors and expansions on legs, antenna or pronotum. Among Neotropical fauna, tribe Acanthocephalini Stål, including 18 genera, recognized by strongly deflexed juga, conspicuously projecting tylus. In same work in which Stål established tribe, he described two new subgenera to genus Acanthocephala Laporte (cur...
Phylogenetic relationships were investigated in the mushroom genus Coprinus based on sequence data from the nuclear encoded large-subunit rDNA gene. Forty-seven species of Coprinus and 19 additional species from the families Coprinaceae, Strophariaceae, Bolbitiaceae, Agaricaceae, Podaxaceae, and Montagneaceae were studied. A total of 1360 sites was sequenced across seven divergent domains and i...
