The status of Longior alius García & Coy, 1994 (Nematoda: Thelastomatoidea: Hystrignathidae) is discussed on the basis of new material obtained from its type host Antillanax pertyi (Kaup, 1869) (Coleoptera: Passalidae) from Limonar, Guantánamo province, Cuba, near the type locality. Based on morphological and molecular studies L. alius is considered synonymous with L. longior Morffe & García, 2011. L. longior and L. similis Morffe, García & Ventosa, 2009 are redescribed and illustrated with the aid of SEM. New locality records for both species are given. The conspecificity of females and males of both species is supported by comparison of the D2-D3 segment of the 28S LSU rDNA. The inter-specific differences and phylogenetic position of L. longior and L. similis are discussed.

Morphological And Molecular Characterization

The females of Xyo pseudohystrix Travassos & Kloss, 1958 (Nematoda: Oxyuridomorpha: Hystrignathidae) are redescribed and illustrated with the aid of SEM. New features of the cephalic end, arrangement of the cervical spines and genital tract were observed. The taxonomic status of the species is discussed on the basis of discrepancies with the generic diagnosis of Xyo Cobb, 1898. Due to the lack of proper information on the genus the status of incertae sedis is proposed. The identity of the males was confirmed by molecular studies and the morphology of the specimens previously assigned by Christie (1932) as males of Hystrignathus rigidus Leidy, 1858 correspond to the current species. New locality records are given for the states of Georgia and Ohio, USA. The phylogenetic position of the species is inferred on the basis of the D2-D3 segment of the LSU rDNA and SSU rDNA.

A New Species

A new species, Pseudodactylaria brevis, is described, illustrated and compared with other Pseudodactylaria and Dactylaria-like taxa. Evidence for the new species is provided by morphological comparison and sequence data analyses. Pseudodactylaria brevis can be distinguished from other Pseudodactylaria and Dactylaria-like species by its short hyaline conidiophores and fusiform, 1-septate hyaline conidia. Phylogenetic analysis of LSU and ITS sequence data was carried out to determine the phylogenetic placement of the species and confirm the taxonomic status of Pseudodactylariaceae.

Taxonomic Assignments

Two rare and endemic psammophines (Serpentes: Psammophiinae) occur in Angola. The taxonomic status of Psammophylax rhombeatus ocellatus Bocage, 1873 and Psammophis ansorgii Boulenger, 1905 have long remained problematic, with both having varied past and present taxonomic assignments, and whose distributions may therefore present zoogeographic anomalies. Little was known of their biology, habitat associations, or phylogenetic relationships. New material was collected during biodiversity surveys of the Humpata Plateau, near Lubango, Angola. It allowed fuller descriptions of scalation and live coloration for both species, and resolution of their taxonomic status. Genetic analysis confirms that both are distinct at the specific level. In addition, within Psammophis, Jalla’s Sand Snake (Psammophis jallae Peracca, 1896), of which P. rohani Angel, 1925, remains a synonym, is sister to P. ansorgii, and Boulenger’s comment on similarities with P. crucifer are not supported. The status of an unusual skaapsteker from Calueque, Cunene Province, Angola, is discussed and its assignment to Ps. ocellatus is provisional and requires additional material for taxonomic resolution. The new P. ansorgii records from Tundavala represent a range (+400 km southwest) and altitude (1800 m to 2286 m a.s.l) extension from the previous only known precise locality of Bela Vista (= Catchiungo), Huambo Province, whilst that for Ps. ocellatus doubles the known altitude from 1108 m to 2286 m a.s.l and extends the range about 122 km to the northwest from historical material from the plateau of Huíla and Cunene provinces.

Morphological And Molecular Data

Several collections of Amanita species from section Vaginatae have been reported to be strictly associated with Helianthemum plants growing in grasslands, a still largely under-explored ectomycorrhizal habitat. The main aim of this study was to investigate the taxonomic status and phylogenetic position of strictly Helianthemum-associated Amanita sect. Vaginatae taxa, informally named Amanita “helianthemicola”. Collections from Italy, England and France were included in this study. The morphologically closely related species complex A. lividopallescens was also examined. Analyses were carried out based on both morphological and molecular data (phylogenetic analysis of the nrITS sequences). All investigated Amanita collections, which are strictly associated with Helianthemum nummularium, turned out to be conspecific with A. simulans. Amanita simulans was recently described from Sardinia (Italy) from Populus nigra habitats based on morphological characters only. As the holotype of A. simulans was lost, a neotype is designated here based on a voucher from the original collecting area. Amanita simulans is re-described, and an extensive discussion on the morphological variability, host species range, distribution and related taxa is provided. Amanita lividopallescens was confirmed as a good species, and re-delimited based on our phylogenetic analysis; moreover, it was epitypified with a recent and well-documented collection from Corse (France). Amanita stenospora is a synonym of A. lividopallescens, being a colour form of the latter without taxonomic value.

Blattophila peregrinata Carreno, 2017 (Nematoda: Oxyuridomorpha: Thelastomatidae) is proposed as a junior synonym of Suifunema peregrinatum (Carreno, 2017) n. comb., based on the revision of the type material of S. caudelli Chitwood, 1932, the type and only species of the genus. The revision permitted the emendation of some features of the original descriptions, namely the position of the nerve ring at level of the corpus instead the isthmus and the female genital tract didelphic-prodelphic instead didelphic-amphidelphic. The males of S. peregrinatum n. comb. are the only ones known for the genus. Thus, an amended generic diagnosis is given, including information on the males. Both S. peregrinatum n. comb. and S. caudelli differ by having a more slender body, a longer tail, and the vulva farther from the anterior end in the former. S. peregrinatum n. comb. is recorded for the first time from Pycnoscelus indicus Fabricius, 1775 (Blattodea: Blaberidae) from Japan. The specimens from Japan are morphologically consistent with other populations of the species from the USA and the Galapagos Islands of Ecuador. Only some morphometrics vary slightly, but these are within the range of the species. The phylogenetic position of the genus among the family Thelastomatidae is discussed, including sequences of the D2-D3 LSU rDNA of specimens from both the type population (Ohio, USA) and Japan.

Abstract Temnocephala axenos Monticelli, 1898 was described based on specimens from an unidentified host collected in Blumenau, Santa Catarina, Brazil. Information about type locality was imprecise and the host was later identified as Aegla laevis (Latreille, 1818). However, it is known that A. laevis is not present on the eastern side of the Andes. Also, only histological preparations from one specimen studied by Monticelli are currently available in the Museum für Naturkunde Berlin, but it showed none of the taxonomic characters needed for the characterization of the species. Although the updated description of the species based on Uruguayan specimens, neither the author nor the several previous studies about the species showed a search for the type material, a resolution for the misidentification of the type host or the imprecise type locality due to the subsequent geographical division of the municipality cited in the description. The Uruguayan specimens were not even geographically close to the type locality and a neotype was not designed to validate the species’ taxonomic status again. Specimens from Santa Catarina and Paraná States, Brazil, were studied, as well as restudied Argentinean specimens. The new data were compared with the update description of the species. The historical background and the discussion about geographical origins and hosts of the species, as well as a designation of a neotype, allow comparative material of the type locality and type host to exist, eliminating doubts about the identification of T. axenos.

The Iberian species of the genera Coscinia Hübner, [1819] and Spiris Hübner, [1819], as well as three other species from the Mediterranean area, are revised based on morphological and molecular genetic data. Our results suggest the separation into four morphologically and phylogenetically different genera: Coscinia Hübner, [1819], Lerautia Kemal & Koçak, 2006 stat. rev., Sagarriella Macià, Mally, Ylla, Gastón & Huertas gen. nov. and Spiris Hübner, [1819]. We conclude that there are eight species of the Coscinia genus group present in the studied area: Coscinia cribraria (Linnaeus, 1758), Coscinia chrysocephala (Hübner, [1810]) stat. rev., Coscinia mariarosae Expósito, 1991, Sagarriella libyssa caligans (Turati, 1907) comb. nov., Sagarriella romei (Sagarra, 1924) (= romeii sensu auctorum) comb. nov., Spiris striata Hübner, [1819], Spiris slovenica (Daniel, 1939) and Lerautia bifasciata (Rambur, 1832) comb. rev. We consider Coscinia cribraria benderi (Marten, 1957) stat. nov., Coscinia c. rippertii (Boisduval, 1834) and Coscinia c. ibicenca Kobes, 1991 stat. rev. to be subspecies of C. cribraria. COI Barcodes of C. cribraria diverge by up to 7.99%, and the investigated specimens group into six different COI Barcode BINs. Both the phylogenetic analysis of mitochondrial and nuclear DNA and the morphological examination of different specimens corroborate the changes in taxonomic status and justify the proposed taxonomic categories. We present images of adults and genitalia of both sexes, the immature stages of some of the species and the subspecies studied, as well as phylogenetic results from the analysis of genetic data. We also include data on life history, foodplants and geographical distribution.

AbstractIn this paper Steringotrema microacetabularis (Suriano et Martorelli, 1983) is redescribed and transferred to Bacciger Nicoll, 1924 in the Faustulidae Poche, 1926 based on newly collected material from the type-host, Paralichthys orbignyanus Valenciennes, 1839 and the type-locality, Mar Chiquita coastal lagoon, Buenos Aires Province, Argentina. A careful re-examination of the new specimens shows that some anatomical characteristics were ignored or incompletely described by the previous authors and they are included herein. The species is tentatively transferred to Bacciger with which it appears to have closest affinity. Despite the anatomical differences detailed in this paper, confirmation of this proposal must await further work, including molecular studies.

New Material

Four Oriental species of Aerumnosa Mohrig, 1999 (Diptera: Sciaridae), a genus previously known only from Papua New Guinea, are newly described and illustrated: Aerumnosa bituberculata sp. n. (India), A. gemmifera sp. n. (Malaysia: Sabah), A. horrifica sp. n. (Brunei, Thailand) and A. impar sp. n. (Malaysia: Sabah). On the basis of the new material, the genus is redefined. A key to the known species of Aerumnosa is presented, including four new species. An updated molecular phylogenetic analysis based on four gene markers (18S, 28S, 16S and COI) shows Aerumnosa to be a member of the subfamily Cratyninae. The monophyly of Cratyninae is well supported, which clade also includes the genera Hyperlasion Schmitz, 1919, Pnyxiopalpus Vilkamaa & Hippa, 1999 and Pseudoaerumnosa Rudzinski, 2006. According to the present phylogenetic hypothesis, the monophyly of Cratyna Winnertz, 1967 s. l. needs to be revisited. The clade including Cratyna (s. str.) ambigua (Lengersdorf, 1934) appears as the sister group of Aerumnosa.
