Notes

Exploration from the cingulate cortex throughout idiopathic generalized epilepsy.
According to mitochondrial cytb sequences, both species are reciprocally monophyletic relative to other species of the A. adloffi species group, and present positive barcoding gap values. Interestingly, both new species form a grade that is closely related to Austrolebias aff. minuano 1, an undescribed species that occurs at the opposite margin of the Laguna dos Patos. Among the other evaluated species, A. bagual, A. aff. minuano 1, A. nigrofasciatus, A. pelotapes, A. pongondo, A. arachan, and A. viarius also revealed to be reciprocally monophyletic, whereas A. minuano and A. adloffi revealed to be paraphyletic in regard to A. charrua and A. aff. minuano 2, respectively, and A. nachtigalli is subdivided in two clades, one of which including A. reicherti, which points to the need of a taxonomic review of the group. In addition, we discussed the conservation status of the new species, corrected the type locality of A. pongondo, and provided a dichotomous identification key of the A. adloffi species group.Heteragrion gorbi sp. nov. (Zygoptera Heteragrionidae) is described and diagnosed based on six ♂♂ and one ♀. The specimens were collected in a stream in a Neotropical savannah fragment in São Carlos, São Paulo, Brazil. We present pictures of the holotype and the female. This is a species with blue coloration pattern, rare among its congeners.Six new epigean freshwater species of the genus Caecidotea in Mexico are described. These species were collected in waterbodies located along the Trans-Mexican Volcanic Belt (TMVB) and the eastern slope of the country Caecidotea buzwilsoni sp. nov., Caecidotea chicoensis sp. nov., Caecidotea alvarezi sp. nov., Caecidotea mintzita sp. nov., Caecidotea zacapuensis sp. nov., and one additional species Caecidotea villalobosi sp. nov. is described from the Papaloapan basin at the Atlantic Slope of Mexico. The taxonomic treatment for each species includes a detailed description, figures of characters of diagnostic importance and comments. We also provide an updated map of Caecidotea records in Mexico. This work substantially increases the number of epigean Caecidotea known to occur in Mexico to 11 species, a new total of 99 species described to North America.The genus Toxicodryas, historically included with the renowned Australasian cat-eyed snakes of the colubrid genus Boiga, currently includes two widespread species (T. blandingii and T. pulverulenta) in western, central, and eastern Africa. We leverage findings from a recent phylogenomic and historical demographic analysis of this genus (based on 2848-4471 Rad-seq loci from across the genome), with robust sampling from throughout the ranges of both species, to define two additional taxonomic units, with species boundaries corresponding to river barriers. Additional morphometric data from scores of examined museum specimens and literature records bolster the recognition of these two new cryptic species. We hypothesize that T. blandingii occurs west of the confluence of the Congo and Ubangi rivers, whereas a cryptic new species that is found east of this biogeographic barrier has significantly higher numbers of ventral scale counts in both sexes, additional significant differences in several scale counts, and lower venom toxicity. Toxicodryas pulverulenta occurs west of the Niger Delta in West Africa, whereas a cryptic new species that is found east of this biogeographic barrier has significantly higher numbers of subcaudal scale counts in both sexes. A review of published information regarding morphological variation, ecology, natural history, habitat, and venom is summarized for these four Toxicodryas species.A new species of Urostylididae from the Philippine islands (Mindanao) is herein described. This new species, similar to Urolabida bipunctata Stål, 1871, differs from the latter in the shape of the external male genitalia. Urolabida bipunctata and the new species, Urolabida graziae Roca-Cusachs, sp. nov., are extremely similar in external appearance, and fit into the (incomplete) description of genus Urolabida Westwood, 1837. The examination and comparison with the type specimens of other Urostylididae species, especially the male genital capsule, clearly separates this two species from Urolabida tenera Westwood, 1837, the type species of the genus Urolabida, however the taxonomy of this group is not resolved and needs a deep revision, therefore we refrain from description of a new genus-group taxon here. Additionally, images of the type specimens of Urolabida tenera, Urostylis histrionica Westwood, 1837, and Urostylis punctigera Westwood, 1837, are provided and discussion on the current systematics and classification of the family, and particularly of genus Urolabida are also given.The stilt bug genus Metajalysus Štusák is revised and three new species are recognized. A neotype of the type species, M. horvathi Štusák, is designated and the new species M. clavatus, n. sp. from Argentina, M. graziae, n. sp. from Argentina and Bolivia, and M. pilosus, n. sp. from Ecuador are described. Digital images of the adult male and female and male genitalia are provided and a key to the species of the genus is given.Only three species assigned to two genera of the flat bug subfamily Carventinae Usinger, 1950 are recorded to date from Costa Rica and one genus and species from Grenada. Following apterous carventine taxa are described and illustrated in the present paper Joceliaptera graziae gen. buy MELK-8a et sp. nov.; Peggicoris cahuitanus sp. nov.; Peggicoris grenadensis sp. nov. Joceliaptera gen. nov. is compared with most similar Neotropical genera. A key to species of Peggicoris is presented.Hyperbius joceliae sp. n., a new Patagonian Acanthosomatidae (Hemiptera) species is described from the north of Tierra del Fuego Island. Diagnostic characters such as color, dorsal pilosity, head and pronotal punctures, length of mandibular plates and antennae, shape and color of paratergite 9, shape and texture of gonocoxite I and II of the only known species of the genus, Hyperbius geniculatus (Signoret), are compared with the new species and discussed. Distributional patterns of the South American Acanthosomatidae and speciation of the Patagonian fauna of this family are also briefly discussed.
