This study delves into the diagnosis of pin nematodes (Paratylenchus spp.) in Spain based on integrative taxonomical approaches using 24 isolates from diverse natural and cultivated environments. Eighteen species were identified using females, males (when available) and juveniles with detailed morphology-morphometry and molecular markers (D2-D3, ITS and COI). Molecular markers were obtained from the same individuals used for morphological and morphometric analyses. The cryptic diversity using an integrative taxonomical approach of the Paratylenchus straeleni-species complex was studied, consisting of an outstanding example of the cryptic diversity within Paratylenchus and including the description of a new species, Paratylenchus parastraeleni sp. nov. Additionally, 17 already known species were identified comprising P. amundseni, P. aciculus, P. baldaccii, P. enigmaticus, P. goodeyi, P. holdemani, P. macrodorus, P. neoamblycephalus, P. pandatus, P. pedrami, P. recisus, P. sheri, P. tateae, P. variabilis, P. veruculatus, P. verus, and P. vitecus. Eight of these species need to be considered as first reports for Spain in this work (viz. P. amundseni, P. aciculus, P. neoamblycephalus, P. pandatus, P. recisus, P. variabilis, P. verus and P. vitecus). Thirty-nine species of Paratylenchus have been reported in Spain from cultivated and natural ecosystems. Although we are aware that nematological efforts on Paratylenchus species in Southern Spain have been higher than that carried out in central and northern part of the country, the present distribution of the genus in Spain, with about 90% of species (35 out of 39 species, and 24 of them confirmed by integrative taxonomy) only reported in Southern Spain, suggest that this part of the country can be considered as a potential hotspot of biodiversity.

A New Species

The assembly of a DNA barcode library for Australian Lepidoptera revealed that Oenochroma vinaria Guenée, 1858, as currently understood, is actually a mix of two different species. By analyzing DNA barcodes from recently collected specimens and the 150 year-old female lectotype of O. vinaria, we propose a reliable assignment of the name vinaria to one of these two species. A lectotype is designated for Monoctenia decora, a confirmed synonym of O. vinaria, and a new species, Oenochroma barcodificata sp. nov., is described. This species is only known from Tasmania and New South Wales; its biology and immature stages are described in detail.

A new species of the Mesobiotus harmsworthi group is described from Datanla Waterfall amusement park in Lâm Đồng Province, Vietnam. An integrative taxonomy approach was applied, by combining morphological and morphometric analyses using light contract microscopy (LCM)) and scanning electron microscopy (SEM) with genetic analysis (18S rRNA, 28S rRNA, ITS-2 and COI markers), to cross-verify the status of the newly discovered population as a new species. By the presence of fully developed areolation around egg processes bases and well developed oral cavity armature (OCA), with all three bands of teeth visible under (LCM), the new species, Mesobiotus datanlanicus sp. nov., is most similar to seven taxa from the harmsworthi complex: M. barbarae (Kaczmarek, Michalczyk & Degma, 2007), M. hieronimi (Pilato & Claxton, 1988), M. insanis Mapalo, Stec, Mirano-Bascos & Michalczyk, 2017, M. neuquensis (Rossi, Claps & Ardohain, 2009), M. nuragicus (Pilato & Sperlinga, 1975), M. pseudoliviae (Pilato & Binda, 1996), M. pseudonuragicus (Pilato, Binda, & Lisi, 2004), but differs from them mainly by some specific characters of the egg and adult morphology as well as by morphometrics.

Abstract Schizodon encompasses approximately 15 species of Neotropical headstanding fishes. Integrative taxonomy, combining molecular and morphometric analyses with traditional taxonomic methods, was used to investigate Schizodon vittatus and its potential new sister species. Molecular differences between the two species in the barcode are greater than intra-specific variation recovered in species of Schizodon, and the two species represent distinct lineages for approximately one million years. The two species are morphologically very similar, and the meristic data showed great overlap. Morphometric analyses also showed overlap among the putative species but indicated differences in caudal-peduncle depth, orbital diameter, and length of anal-fin rays. Color pattern seems to provide a clear diagnostic feature for the two species. Schizodon vittatus usually has four dark brown transversal bars on body, and its sister species has three conspicuous bars, with the fourth, if present, inconspicuous and dorsal to the lateral line. Schizodon vittatus is redescribed based on the type and recently collected specimens, its type locality is revisited, and its known distribution restricted to the Araguaia and Tocantins drainages. The new species, sister to S. vittatus, distributed in the Xingu and Tapajós drainages, is described. A key for the identification of the Amazon clade species of Schizodon is provided.

AbstractThe ghost shrimp Callichirus major (Say, 1818) is widely distributed in the Atlantic Ocean from ∼23°N to ∼26°S, and has also been reported from the tropical eastern Pacific. Evidence has been accumulating over many years that C. major is actually a species complex. Yet, the name C. major is widely and frequently used in many kinds of research. The current lack of clarity in the use of the name C. major has resulted in nomenclatural instability, but also in unreliability and miscommunication of the available ecological and distributional information. Existing morphological and molecular evidence is reviewed and new evidence presented for the specimens from the southern localities previously assigned to C. major s. l. actually being a new species. That new species is herein described based on morphological and molecular evidence. Additionally, a neotype is selected for C. major in order to settle the defining characters of C. major s. str. and, therefore, ensuring the correct use of this name.

AbstractThe taxonomy of Merodon dobrogensis Bradescu, 1982 (Diptera: Syrphidae) species subgroup was reviewed. Multiple data sources (morphology, geometric morphometry of wings and surstylus, molecular data, and distributional data) were used to investigate the species subgroup in the manner of integrative taxonomy. Merodon dobrogensis Bradescu, 1982 and M. puniceus Vujić, Radenković, and Pérez-Bañón, 2011 are supported as distinct species belonging to the M. dobrogensis species complex within the M. dobrogensis species subgroup. Additionally, evidence is presented for the description of a new species, M. rojoi Radenković and Vujić new species, with a distribution in mainland Greece, the Greek island Euboea, and the Peloponnese. A short diagnosis is provided for the M. aureus species group, the M. dobrogensis species subgroup, and the newly defined M. dobrogensis species complex, in addition to a description of the new species, with drawings and photographs of adult morphology.
