Nine new species of the collembolan genus Salina MacGillivray from South America are described and illustrated. Two Neotropical species were recorded for the first time from Brazil: S. dedori s Mari-Mutt and S. tristani Denis. Salina was previously known to occur in three Brazilian states, and this is now updated to include 19 states with 12 recorded species. A new proposal of morphological character description and illustration, and an identification key for the celebensis group are provided. A hypothesis for the phylogenetic relationships among 34 species of Salina (about 50% of the 72 described species) allowed three main pursuits: (a) a reevaluation of Salina species groups; (b) the first explicit interpretation of how morphological characters of these springtails may have changed during the course of the diversification of the taxon; and (c) an evaluation of the historical biogeographic connections of Salina , with an emphasis on the celebensis group distribution to the New World.
描述并说明了来自南美洲的九种新属。在巴西首次记录到2个新热带种:s. dedori s Mari-Mutt和s. tristani Denis。以前已知的盐林娜发生在巴西的三个州，现在更新到包括19个州和12个记录的物种。提出了一种新的形态特征描述和图解方法，并给出了一种新的识别钥匙。对34种盐藻(约占已描述的72种中的50%)的系统发育关系进行了假设，主要有三个方面:(A)对盐藻物种群的重新评估;(b)首次明确解释了这些弹尾在分类群多样化过程中形态特征的变化;(c)对Salina的历史生物地理联系进行评估，重点是celebensis群体在新大陆的分布。

The tribe Sisyphini sensu stricto Mulsant, 1842 comprises only three genera, the widespread Sisyphus Latreille, 1807 and Neosisyphus Müller, 1942, and the Mauritius endemic, Nesosisyphus Vinson, 1946. In southern Africa, Sisyphus and Neosisyphus are represented by five species groups in each genus. Together, they comprise a total of 33 valid species, of which six are new: Sisyphus auricomus sp. n; Sisyphus australis sp. n ; Sisyphus bicuariensis sp. n; Sisyphus inconspicuus sp. n; Sisyphus swazi sp. n; and Neosisyphus tembyi sp. n. A further Southern African species, Sisyphus crispatus Gory, 1833, is proposed as a nomen dubium. Sisyphus natalensis Balthasar, 1968 (syn. n), and Sisyphus bornemisszanus Endrödi, 1983 (pars) (syn. n) are made synonyms of Sisyphus sordidus Boheman, 1857. Lectotypes and paralectotypes are designated for Sisyphus costatus (Thunberg, 1818); Sisyphus seminulum Gerstaecker, 1871; Sisyphus nanniscus Péringuey, 1901; Sisyphus transvaalensis Péringuey 1901; Neosisyphus spinipes (Thunberg, 1818) and Neosisyphus barbarossa (Wiedemann, 1823). Diagnoses, photographs of habitus and male genitalia, lists of examined material and distribution maps are presented for all species. An identification key to the southern African sisyphine species is provided.

This study focuses on the Brazilian species of the genus Purenleon Stange (Neuroptera: Myrmeleontidae). A total of five species are herein reported to Brazil: Purenleon clavatus (Navás), Purenleon fernandezi Miller & Stange (first record for Brazil), Purenleon cautus (Walker) comb. n., and two new species: Purenleon limeirai sp. n. and Purenleon rafaeli sp. n. The taxonomical status of other two species was reevaluated: Formicaleo bipunctatus Navás was synonymized under P. cautus and Feinerus nebulosus Navás was revalidated and transferred to Purenleon. A key to the South American species of Purenleon is also presented.

We present herein the first phylogenetic analysis of the genus Chelidura and the taxonomic revision of the genus Chelidurella, stat. restit., based on DNA sequences. The results confirm the generic status of Chelidurella Verhoeff, 1902 and Mesochelidura Verhoeff, 1902, and they are removed from the synonymy with Chelidura and reinstated as valid genera. Many individual Chelidurella species are defined based on the combination of a few variable characters on the pygidium and forceps, and the systematics and phylogeny of this genus are unclear. The validity of most of the species is revisited here by molecular phylogenetic analyses, and individual morphological characters are evaluated for their relevance in the identification of all described species. We describe two new species to science, Chelidurella galvagnii Kirstová & Kočárek, sp. nov. from Austria, and C. pseudovignai Kočárek & Kirstová, sp. nov. from Italy and Austria; two species, C. guentheri Galvagni, 1994 and C. tatrica Chládek, 2017 are newly synonymized. Critical diagnostic characters are illustrated, and an identification key for males of Chelidurella is provided.

The genus Melissodes Latreille in the subfamily Eucerinae (Hymenoptera: Apidae) is a widespread and common group of bees. There are 129 described Melissodes species that range throughout the western hemisphere with the center of diversity in the warm deserts of southwestern North America. Despite its widespread nature and importance in agriculture, the evolutionary relationships among the species have never been investigated. Here, we present a molecular phylogeny using five loci for 89 species of Melissodes with representatives from all subgenera. We confirm all of the subgeneric delineations constructed by LaBerge, except for a paraphyletic M. (Tachymelissodes) and the placement of M. (Heliomelissodes), which renders M. (Eumelissodes) paraphyletic. We also discuss the unexpected placement of M. tristis Cockerell, M. paucipuncta LaBerge, M. dagosus Cockerell, and M. pexa LaBerge. Finally, we combine this analysis with previous data to support the placement of Melissodes within the subfamily Eucerinae.

The species Calyptra minuticornis is divided into two subspecies: C. minuticornis novaepommeraniae (Strand) and C. minuticornis minuticornis (Guenée) based on minor morphological differences, geographic distribution, and differential feeding behaviors in the adults. In this study, museum specimens were examined, including the holotypes of C. novaepommeraniae and C. minuticornis. A comprehensive distribution map was generated for C. minuticornis. A permutational multivariate analysis of variance provided some statistical evidence for minor differences between the male genitalic morphology. Additionally, the maximum parsimony analysis of the C. minuticornis subspecies complex resulted in a polytomy and did not represent natural groupings. From these results, it can be concluded that C. minuticornis novaepommeraniae and C. minuticornis minuticornis should be synonymized. A redescription of the species and a revised checklist for the genus is also provided. This includes synonymization of Wolframmeyia Behounek, Hacker & Speidel with Calyptra and evidence that Percalpe Berio is an unavailable name.

Platygerris White comprises true bugs that inhabit the surface of water in moderate to fast-flowing freshwater habitats. This genus differs from Cylindrostethus Mayr and Potamobates Champion (Gerridae: Cylindrostethinae) by having a short and flattened body; the mandibular and maxillary plates fused; and the omphalium, lateral groove, and lateral evaporatorium of the scent apparatus inconspicuous. In this paper, we redescribe Platygerris, describe two new species from Colombia, and redescribe P. asymmetricus Hungerford, P. caeruleus Champion and P. depressus White. In addition, we present an updated identification key to the species of the genus. For the first time, the cuticular structure is described for the genus based on electron microscopy.

The subgenus Canthon (Pseudepilissus) Martínez, 1954 is revised. Four valid species are redescribed: Canthon (Pseudepilissus) muticus Harold, 1867; C. (P.) lunatus Schmidt, 1922; C. (P.) planus Lucas, 1857 and C. (P.) reichei Felsche, 1910. Three species assigned to other groups are transferred in the subgenus: C. (P.) quadratus Blanchard, 1843 [previously Canthon “incertae sedis”]; C. (P.) edentulus Harold, 1868 [previously Canthon “incertae sedis”] and C. (P.) seminulus Harold, 1867 comb. nov. [previously Vulcanocanthon]. The genus Vulcanocanthon Pereira & Martínez, 1960 syn. nov. is synonymized with Canthon (Pseudepilissus). Three subspecies are raised to species level: C. (P.) tibialis Schmidt, 1922 stat. nov. [previously C. (P.) lunatus tibialis]; C. (P.) granuliceps Felsche, 1910 stat. nov. [previously C. edentulus granuliceps] and C. (P.) hendrichsi Halffter & Martínez, 1968 stat. nov. [previously C. (P.) muticus hendrichsi]. C. (P.) honsi Balthasar, 1939 syn. nov. is synonymized with C. (P.) reichei Felsche, 1910. Four new species are described: Canthon (P.) arriagadai sp. nov., Canthon (P.) bonaerensis sp. nov., Canthon (P.) vidaurrei sp. nov. and Canthon (P.) ziggy sp. nov., bringing the number of species in the subgenus to 14. Lectotypes are designated for six species C. (P.) muticus Harold, 1867; C. (P.) reichei Felsche, 1910; C. (P.) planus Lucas, 1857; C. (P.) seminulus Harold, 1867; C. (P.) granuliceps Felsche, 1910 and C. (P.) quadratus Blanchard, 1843. A detailed literature review, synonymies, description, illustration of key morphological characters, data on the studied material and geographic distribution are provided for each species.
