The spider genus Ariadna Audouin, 1826 currently comprises 102 of 127 described species of Segestriidae. Its distribution comprises all continents (except Antarctica), but it is mostly found on the tropical and subtropical regions. We present a comprehensive taxonomic revision of Ariadna in the American continent, including 2,519 specimens (i.e., type and non-type) from 30 arachnological collections. We present 31 nominal species, among which eight species are new to the science: Ariadna reginae n. sp. from Central America; Ariadna aurea n. sp., Ariadna caparao n. sp., Ariadna gaucha n. sp., Ariadna ipojuca n. sp., Ariadna lemosi n. sp. and Ariadna ubajara n. sp. from Brazil; and Ariadna lalen n. sp. from Chile. Nine species are proposed as junior synonyms: A. pragmatica Chamberlin, 1924 and A. scholastica Chamberlin, 1924 with A. bicolor (Hentz, 1842), A. gracilis Vellard, 1924 and A. conspersa Mello-Leitão, 1941 with A. obscura (Blackwall, 1858), A. murphyi (Chamberlin, 1920) with A. tarsalis Banks, 1902, A. pusilla (Nicolet, 1849) and A. ashantica Strand, 1916 with A. maxima (Nicolet, 1849), A. dubia Mello-Leitão, 1917 with A. boliviana Simon, 1907, and A. spinifera Mello-Leitão, 1947 with A. mollis (Holmberg, 1876). Ariadna comata O. P.-Cambridge, 1898 is revalidated. Two species became nomina dubia: Ariadna solitaria Simon, 1892 and A. tubicola Simon, 1893. The allotype of A. crassipalpa described by Camargo (1950) and the paratype of A. levii described by Grismado (2008), were identified as A. mollis and A. maxima, respectively and have been considered as misidentifications. The male of A. cephalotes and A. comata, and the female of A. calilegua are described for the first time.

The Neotropical thread-legged bug genus Ghilianella Spinola, 1850 is the most diversified within Metapterini. A taxonomic revision of Ghilianella is presented, in which seventy seven species are recognized as valid, with twenty-one described as new: Ghilianella berengeri sp. nov.; Ghilianella bifurcata sp. nov.; Ghilianella bolivari sp. nov.; Ghilianella caldensis sp. nov.; Ghilianella dilatata sp. nov.; Ghilianella embera sp. nov.; Ghilianella fernandezi sp. nov.; Ghilianella ferruginosa sp. nov.; Ghilianella gilsantanai sp. nov.; Ghilianella goliath sp. nov.; Ghilianella gracilis sp. nov.; Ghilianella huaorani sp. nov.; Ghilianella jaguar sp. nov.; Ghilianella laticauda sp. nov.; Ghilianella maricruzae sp. nov.; Ghilianella quimbaya sp. nov.; Ghilianella scimitarra sp. nov.; Ghilianella tica sp. nov.; Ghilianella urbanoi sp. nov.; Ghilianella ventrimaculata sp. nov.; and Ghilianella weirauchae sp. nov. For the first time a female specimen is described for Ghilianella atriclava Bergroth, 1911, Ghilianella colona McAtee & Malloch, 1925 and Ghilianella pachitea McAtee & Malloch, 1925. Three new synonyms are recognized: Ghilianella bulbifera Champion, 1898 (=Ghilianella pendula McAtee & Malloch, 1925 syn. nov.; Ghilianella inflata Maldonado, 1981 syn. nov.) and Ghilianella strigata McAtee & Malloch, 1925 (=Ghilianella fenestrata Maldonado, 1960 syn. nov.). Eleven species are considered nomina dubia and one species nomen nudum. A key to species and digital images of the external morphology and genitalic structures for each species are provided. Additionally, we offer the first phylogenetic hypothesis of relationships within Ghilianella, using cladistic methods. Based on the phylogenetic results we dismiss all subgenera in Ghilianella and discuss the complex evolution of the abdominal expansions.

Phyxioschema raddei Simon, 1889 is revised. A re-examination of type specimens confirms the synonymy of P. raddei and Ischnothele strandi Spassky, 1937, but the synonymy of Afghanothele lindbergi Roewer, 1960 and A. striatipes Roewer, 1960 cannot be confirmed due to the immature state of their types. The copulatory organs of the female holotype and other females from different localities are illustrated for the first time. Variation in morphological characters is shown. New records are given for Iran, Turkmenistan, Uzbekistan, Kazakhstan and Tajikistan. Phyxioschema females from Pakistan cannot be attributed to any nominal species and are left unnamed. A new species, P. roxana, is described from male and female specimens collected at eight localities in southern Uzbekistan and western Tajikistan. Relationships between Central Asian and Southeast Asian species are discussed. A summary of relevant morphological characters of all Phyxioschema species is given.

We morphologically validate the genus Schausiana Viette, 1950 as a monophyletic group comprising five species—S. phalerus (Druce, 1887) comb. n. and S. trojesa (Schaus, 1901) from Mexico, S. chalciope sp. n. and S. maishei sp. n. from Guatemala and S. pharus (Druce, 1887) comb. n. from Mexico to Costa Rica. Potential morphological monophyly of the genus is supported by the unique shared presence of specialized scales spine-like, elongate spinous, or piliform, located along the forewing veins. We investigate possible close phylogenetic relationships of this genus with the Mexican and Central American genera Pallas C. Mielke & Grehan, 2015, and Phassus Walker, 1856, and the southeastern Brazilian genus, Phthius C. Mielke & Grehan, 2017. Also discussed are the shared presence of several characters supporting the morphological monophyly of Schausiana, Phassus, and Pallas as ‘phassine’ Hepialidae. The distribution range of Schausiana is bounded in its northwestern range by the Guerrero terrane. Other than the widespread S. pharus with a disjunct record from Costa Rica, the southern distribution boundary corresponds to the Motagua-Polochic Fracture Zone in Guatemala. We suggest that the ancestral range of Schausiana did not include the Guerrero terrane and was possibly also absent from the Chocos Block (Honduras, El Salvador, Nicaragua) and the Costa Rica-Panama arc of Central America. Further divergence of Schausiana is predicted to have been influenced by tectonic events during late Cretaceous or early Cenozoic time. Colour photos are presented for all species for the first time. Holotypes of S. maishei, sp. n., and S. chalciope, sp. n., are deposited in the Universidad del Valle de Guatemala, Guatemala.

The Epicauta vittata group are commonly known as striped blister beetles and was defined by previous authors to include 32 species, 18 from North America, Central America and northern South America, and 14 from southern South America. In the present revision we revised 22 species from South America, excluding the following southern South American species: E. borgmeieri Denier, 1935; E. floydwerneri Martínez, 1955; E. franciscana Denier, 1935; E. fulginosa (Oliver, 1795); E. purpureiceps (Berg, 1889); E. rutilifrons Borchmann, 1930; and E. zebra (Dohrn, 1876) because they do not have the diagnostic characters of the group. The species of the E. vittata group from southern South America are: E. bosqi Denier, 1935; E. clericalis (Berg, 1881); E. grammica (Fischer, 1827); E. leopardina (Haag-Rutemberg, 1880); E. luteolineata Pic, 1933; E. missionum (Berg, 1881); E. monachica (Berg, 1883); E. rutilifrons Borchmann, 1930; plus two more species E. excavata (Klug, 1825); and E. semivittata (Fairmaire, 1875) until now not included in other groups. We provide a complete diagnosis of the E. vittata group from southern South America, redescribing and illustrating all included species. Detailed descriptions and illustrations of female and male genitalia are presented for the first time for these species. Finally, we provide an identification key for the ten species presently included in the E. vittata group, and update the geographic distribution of each species.

Citharexylum L. belongs to the recently circumscribed tribe Citharexyleae of the Verbenaceae, along with Rehdera Moldenke. It comprises around 50 to 60 species of trees and shrubs growing in the Neotropics. A complete taxonomic revision of Citharexylum in South America is here provided for the first time. Thirty taxa are present in South America, 27 of these are endemic, and three of them also grow in Central America. Detailed morphological descriptions are given for each taxon, as well as a key for their identification; illustrations, photographs, or iconography; updated synonymy; geographic distribution maps and ecological notes; list of selected specimens; and discussion about the relationship among closely related taxa. A new status, C. poeppigii Walp. var. anomalum (Moldenke) N. O’Leary, and a new combination, C. dentatum D. Don var. canescens (Moldenke) N. O’Leary, are proposed. Thirty-five new synonyms are suggested, and lectotypes are designated for C. fruticosum L. var. brittonii (Moldenke) I. E. Méndez, C. laurifolium Hayek, and Rauvolfia spinosa Cav.

A taxonomic revision of the stygobiont microsnails from north-western Transcaucasia (Krasnodar Krai, Russia) is presented. Two new genera—Schapsugia gen. n. and Tachira gen. n. are established. It is shown that the genus Paladilhiopsis does not occur in this area, and the snails previously assigned to this genus belong to Schapsugia gen. n. Two nominal species Paladilhiopsis orientalis Starobogatov, 1962, and P. subovata Starobogatov, 1962 are considered junior synonyms of Sch. pulcherrima (Starobogatov, 1962), based on a re-examination of their conchological variation. In addition, two more species of Schapsugia are described: Sch. kudepsta sp. nov. and Sch. occultata sp. nov. The anatomical structure of another species, Geyeria valvataeformis Starobogatov, 1962 was studied for the first time. It is revealed that it should be placed in a separate genus (Tachira gen. n.). Thus, the previously proposed placement of the microsnails from north-western Transcaucasia in hydrobiid genera from the Balkan Peninsula (Geyeria, Paladilhiopsis) is rejected.

Three new species of Otostigmus Porat, 1876 from Brazilian Atlantic Forest are described. Otostigmus beckeri sp. n. andO. lanceolatus sp. n. are described from the state of Bahia and O. giupponii sp. n. from the state of Espírito Santo. InBrazil, the otostigmine scolopendrid genus Otostigmus comprises 22 species. A summary of Brazilian Otostigmus speciesis presented with new distribution records, taxonomic remarks when appropriate and an identification key. Otostigmus sul-catus Meinert, 1886 is recorded for the first time from Brazil; the Andean Otostigmus silvestrii Kraepelin 1903, previouslyrecorded from Brazil, is here considered not to be present in this country. Eight nominal species are regarded here as newsynonyms. Five of them—Otostigmus pradoi Bücherl, 1939, O. longistigma Bücherl, 1939, O. longipes Bücherl, 1939,O. langei Bücherl, 1946 and O. dentifusus Bücherl, 1946—are based on females of O. tibialis Brölemann, 1902. O. latipesBücherl, 1954 is conspecific with and is considered a junior synonym of O. sulcatus Meinert, 1886; O. limbatus diminutusBücherl, 1946 is a junior synonym of O. limbatus Meinert, 1886 and O. fossulatus Attems, 1928 is a junior synonym of O. goeldii Brölemann, 1898. A lectotype is designated for O. goeldii.
