The primarily Palearctic Diorhabda elongata species group is established for five Tamarix-feeding sibling species(tamarisk beetles): D. elongata (Brullé, 1832), D. carinata (Faldermann, 1837), D. sublineata (Lucas, 1849) REVISEDSTATUS, D. carinulata (Desbrochers, 1870), and D. meridionalis Berti & Rapilly, 1973 NEW STATUS. Diorhabdakoltzei ab. basicornis Laboissière, 1935 and D. e. deserticola Chen, 1961 are synonymized under D. carinulata NEWSYNONYMY. Illustrated keys utilize genitalia, including male endophallic sclerites and female vaginal palpi andinternal sternite VIII. Distribution, comparative biogeography, biology, and potential in biological control of Tamarix inNorth America are reviewed. Diorhabda elongata is circummediterranean, favoring Mediterranean and temperate forestsof Italy to western Turkey. Diorhabda carinata resides in warm temperate grasslands, deserts, and forests of southernUkraine south to Iraq and east to western China. Diorhabda sublineata occupies Mediterranean woodlands from Franceto North Africa and subtropical deserts east to Iraq. Diorhabda carinulata primarily inhabits cold temperate deserts ofMongolia and China west to Russia and south to montane grasslands and warm deserts in southern Iran. Diorhabdameridionalis primarily occupies maritime subtropical deserts of southern Pakistan and Iran to Syria. Northern climatypesof D. carinulata are effective in Tamarix biological control, especially in the Great Basin desert. Diorhabda elongata isprobably best suited to Mediterranean woodlands of northern California. Northern climatypes of D. carinata may be bestsuited for central U.S. grasslands. Diorhabda sublineata, D. meridionalis, and southern climatypes of D. carinata and D. carinulata may each be uniquely suited to areas of the southwestern U.S.

Species Taxonomy

We studied the taxonomic status of the north African Agama species A. impalearis, A. castroviejoi, and A. boueti. The study of recently collected specimens and museum material, as well as phylogenetic analyses of a short 16S ribosomal RNA gene fragment, revealed the presence of an undescribed species in Adrar des Ifoghas (Mali), Aïr Mountains (Niger), Ahaggar Mountains (Algeria) and Tassili n’Ajjer (Algeria, Lybia), previously mistaken either as A. impalearis or A. agama. The new species, Agama tassiliensis n. sp., clearly belongs to the impalearis – boueti – spinosa species group but differs from these species, among other characters, by its red, reddish-orange or orange vertebral stripe in males, long and angular head, long limbs and toes (with 4 th toe usually slightly longer than 3 rd toe), long but low nuchal crest made of 10 to 15 spines (rarely 8–9 spines) and large number of supralabials (10–16, usually around 12). Interspecific uncorrected p- distances based on the 16S rDNA gene fragment are high, ranging from 3.9% between A. boueti and A. impalearis to 7.9% between A. spinosa and A. impalearis. The new species is sympatric with A. boueti at least in the Aïr Mountains and exhibits average mtDNA divergences of 6.2%, 7.4%, and 7.6% with A. spinosa, A. impalearis, and A. boueti, respectively. Agama boueti is paraphyletic relative to A. castroviejoi in the mtDNA tree, and mtDNA genetic divergences between populations of both species are lower than 1.0%, suggesting that A. castroviejoi is better treated as a junior synonym of A. boueti pending more detailed analyses. Scattered mountain ranges in the Sahara seem to have promoted lineage divergence and ultimately speciation in this group. Further work should be done to study species taxonomy and evolution in those areas.

AbstractThe species of the genus Entomacis Foerster in North America north of Mexico are revised. Nineteen species (12 new), including 8 species of the Holarctic-wide perplexa species group, are keyed, described, and figured. These taxa are E. ambigua (Brues), E. apopkaensissp. nov., E. arcticasp. nov., E. cellariasp. nov., E. cepasp. nov., E. eorariasp. nov., E. floridana (Ashmead), E. grandiclavasp. nov., E. longii (Ashmead), E. mellipetiola (Ashmead), E. parambiguasp. nov., and perplexa group members E. californica (Ashmead), E. microbipunctatasp. nov., E. notioxerasp. nov., E. oulasp. nov., E. parvasp. nov., E. perplexa (Haliday), E. sapratasp. nov., and E. subemarginata (Ashmead). Hemilexodes canadensis (Harrington) is synonymized under Entomacis mellipetiola (Ashmead) (syn. nov.). The status of Entomacis latipennis (Ashmead), E. filiformis (Ashmead), and Hemilexis jessei Mann is reviewed. New character complexes, particularly chaetotaxy, are emphasized for Diapriidae species taxonomy.

Species Taxonomy

ABSTRACTBotulinum neurotoxins (BoNTs) are produced by a diverse set of seven clostridial species, though alternate naming systems have developed over the last 100 years. Starting in the 1950s, a single-species taxonomy where any bacterium producing BoNT would be designatedClostridium botulinumwas introduced. As the extreme diversity of these strains was recognized, a secondary system of taxonomic “groups” evolved. It became clear that these groups also had members that did not produce BoNT, and in some cases, they were given formal species names. Genomic analysis now clearly identifies species affiliations whether an isolate is toxigenic or not. It is clear thatC. botulinumgroup nomenclature is no longer appropriate and that there are recognized species names for each clostridium. We advocate for the use of the scientific binomials and that the single-species group nomenclature be abandoned.

Species Inquirendae

The species of the subgenus Inaequalium are reviewed based on adult and pupal morphology. All main taxonomic characters are fully illustrated together with a key to pupae for species identification. Discussions on the species’ taxonomy and brief summaries of their distribution and biology are also provided. As a result of this study, 14 species are now included in the subgenus Inaequalium. They are placed into two species groups, the botulibranchium species group with three species and the inaequale species group with 11 species, including two that are treated as species inquirendae: S. lurybayae Smart and S. parimaense Ramírez-Pérez, Yarzábal, Takaoka, Tada & Ramírez. Simulium lurybayae Smart, S. margaritatum Pepinelli, Hamada & Luz and S. maranguapense (Pessoa, Ríos-Velásquez & Py-Daniel) are now placed in the inaequale species group. Two lectotypes are designated for the following species: S. clavibranchium Lutz and S. diversibranchium Lutz. Simulium hauseri (Coscarón & Coscarón-Arias) is regarded as an unavailable name.
