Os artrópodes (Arthropoda) dos arquipélagos da Madeira e das Selvagens

Os artrópodes terrestres (e.g. aranhas, ácaros, outros aracnídeos, crustáceos, centopeias, diplópodes, insectos, etc.) são o grupo de animais dominante na Terra. Nos arquipélagos da Madeira e das Selvagens, este grupo é também o mais diverso e inclui espécies associadas a uma grande variedade de ecossistemas. 2. Com base na revisão detalhada da bibliografia existente e de outros registos não publicados, foram listados 3891 taxa (espécies e subespécies) de artrópodes terrestres, que pertencem a 462 famílias e 2118 géneros. O subfilo Hexapoda (no qual estão incluídos os insectos) é o mais diverso de todos os subfilos de artrópodes, com 3394 taxa, o que corresponde a 87% de todos os artrópodes.ABSTRACT: Terrestrial arthropods (e.g. spiders, mites, other arachnids, crustaceans, centipedes, millipedes, insects, etc.) are the dominant life form on Earth. In the archipelagos of Madeira and Selvagens this group of animals is also the most diverse and includes species associated to a wide variety of ecosystems. 2. Based on a detailed literature survey, including both published and unpublished records, 3,891 taxa (species and subspecies) of terrestrial arthropods belonging to 462 families and 2,118 genera were recorded for Madeira and Selvagens. The subphylum Hexapoda, which includes highly diverse insects, is by far the most diverse of all arthropod groups with 3,394 taxa (i.e. 87 % of all arthropods)

Distributional Patterns of Pseudacteon Associated with the Solenopsis saevissima Complex in South America

Classical biological control efforts against imported fire ants have largely involved the use of Pseudacteon parasitoids. To facilitate further exploration for species and population biotypes a database of collection records for Pseudacteon species was organized, including those from the literature and other sources. These data were then used to map the geographical ranges of species associated with the imported fire ants in their native range in South America. In addition, we found geographical range metrics for all species in the genus and related these metrics to latitude and host use. Approximately equal numbers of Pseudacteon species were found in temperate and tropical regions, though the majority of taxa found only in temperate areas were found in the Northern Hemisphere. No significant differences in sizes of geographical ranges were found between Pseudacteon associated with the different host complexes of fire ants despite the much larger and systemic collection effort associated with the S. saevissima host group. The geographical range of the flies was loosely associated with both the number of hosts and the geographical range of their hosts. Pseudacteon with the most extensive ranges had either multiple hosts or hosts with broad distributions. Mean species richnesses of Pseudacteon in locality species assemblages associated with S. saevissima complex ants was 2.8 species, but intensively sampled locations were usually much higher. Possible factors are discussed related to variation in the size of geographical range, and areas in southern South America are outlined that are likely to have been under-explored for Pseudacteon associated with imported fire ants

Presence of Crumomyia glacialis (Meigen, 1830) (Diptera: Sphaeroceridae) in the Sierra Nevada and Sierra de Guadarrama National Parks (Spain): first record from the Iberian Peninsula, and evidence of its presence in the Mesovoid Shallow Substratum

The sphaerocerid Crumomyia glacialis (Meigen, 1830) is recorded from the Iberian Peninsula for the first time. The specimens were captured in two Spanish National Parks (Sierra Nevada N. P. and Sierra de Guadarrama N. P.). Most of the specimens (6 out of 7) were captured in the Mesovoid Shallow Substratum by means of subterranean sampling devices (SSD), and only one with epigean pitfall traps. In addition to this first record, the implications of the presence of this species in the high mountain MSS are discussed

Catalogue of the Diptera (Insecta) of Morocco- an annotated checklist, with distributions and a bibliography.

The faunistic knowledge of the Diptera of Morocco recorded from 1787 to 2021 is summarized and updated in this first catalogue of Moroccan Diptera species. A total of 3057 species, classified into 948 genera and 93 families (21 Nematocera and 72 Brachycera), are listed. Taxa (superfamily, family, genus and species) have been updated according to current interpretations, based on reviews in the literature, the expertise of authors and contributors, and recently conducted fieldwork. Data to compile this catalogue were primarily gathered from the literature. In total, 1225 references were consulted and some information was also obtained from online databases. Each family was reviewed and the checklist updated by the respective taxon expert(s), including the number of species that can be expected for that family in Morocco. For each valid species, synonyms known to have been used for published records from Morocco are listed under the currently accepted name. Where available, distribution within Morocco is also included. One new combination is proposed: Assuaniamelanoleuca (Séguy, 1941), comb. nov. (Chloropidae)
