Amphiphala Roberts and Sabourin, new genus (Lepidoptera: Tortricidae), is proposed for three new species: A. liatriana Roberts and Sabourin, new species; A. landryana Brown, new species; and A. carolana Sabourin, new species. The genus is recorded from the eastern part of North America from Ontario, Canada south to South Carolina, and west to Manitoba and Mississippi. Owing to its superficial similarity to the banded sunflower moth, Cochylichroa hospes (Walsingham, 1884), Amphiphala remained hidden in North American Lepidoptera collections. Amphiphala liatriana has been reared from northern blazing star, Liatris scariosa (L.) Willd. (Asteraceae), in Maine.

The genus Elmomorphus Sharp, 1888 is redescribed based on morphological characters. Elmomorphus bryanti Hinton, 1935, E. montanus (Grouvelle, 1913), E. prosternalis Hinton, 1935, and E. striatellus Delève, 1968 are redescribed based on type material. Elmomorphus nepalensis Satô, 1981 is redescribed based on material collected in the vicinity of the type locality. Eighteen species of Elmomorphus were known so far world-wide, and only five species have been recorded from the study area (India, Nepal, Bhutan, Myanmar, China, Thailand, Laos, Cambodia, and Vietnam). In the present revision, 45 new species are described: E. auratus sp. nov. (China), E. auripilosus sp. nov. (Vietnam), E. bispinosus sp. nov. (China), E. calvus sp. nov. (China, Vietnam), E. catenatus sp. nov. (China), E. comosiclunis sp. nov. (China), E. corpulentus sp. nov. (China), E. cuneatus sp. nov. (Thailand), E. curvipes sp. nov. (China, Vietnam), E. dentipes Kodada, Selnekovič & Jäch sp. nov. (China, Laos, Myanmar, Thailand, Vietnam), E. depressus sp. nov. (China), E. donatus Kodada, Selnekovič & Jäch sp. nov. (China, Vietnam), E. ellipticus sp. nov. (China), E. elmoides sp. nov. (Vietnam), E. fusiformis sp. nov. (China), E. glabriclunis sp. nov. (China), E. globosus sp. nov. (China), E. hamatus sp. nov.

(China, Laos, Malaysia, Myanmar, Thailand, Vietnam), E. parvulus sp. nov. (Thailand), E. punctulatus sp. nov. (China), E. reticulatus sp. nov. (China), E. sausai Kodada, Selnekovič & Jäch sp. nov. (Vietnam), E. schillhammeri sp. nov. (China), E. schoenmanni sp. nov. (China), E. siamensis Kodada, Selnekovič & Jäch sp. nov. (Cambodia, Laos, Myanmar, Thailand, Vietnam), E. similis sp. nov. (China, Laos, Vietnam), E. simplex sp. nov. (China), E. simplipes sp. nov. (Vietnam), E. superficialis sp. nov. (China), E. sulcatus sp. nov. (China), E. umphangicus Kodada, Selnekovič & Jäch sp. nov. (Thailand), E. vietnamensis sp. nov. (Vietnam), and E. yunnanensis Kodada, Selnekovič & Jäch sp. nov. (China). The genus Elmomorphus is recorded for the first time from Bhutan, Cambodia, Myanmar, and Laos. In China (31 spp. from Anhui, Fujian, Guangdong, Guangxi, Guizhou, Hainan, Hong Kong, Hubei, Hunan, Jiangxi, Shaanxi, Yunnan, Zhejiang) and Vietnam (16 spp.), this genus is especially diverse.
In this study, we describe two new species of Mesobiotus based on morphological data collected through light and scanning electron microscopy. Descriptions include DNA sequences of four commonly used molecular markers (18S rDNA, 28S rDNA, ITS-2, and COI). Mesobiotus efa sp. nov. was discovered in North-West Russia and belongs to the group of species with smooth cuticle, harmsworthi-type OCA, typical Mesobiotus claws IV with unindented lunules, and egg chorion with reticulated processes in form of ‘sharp wide cones’ or ‘cones with long slender endings’, egg process bases with well-developed crone of dark thickenings without finger-like projections, and egg shell surface between the processes with ridges without reticulation, areolation or semi-areolation. It can be distinguished from all know species of this group by a unique combination of morphological and morphometric characters. Mesobiotus vulpinus sp. nov. was found in the Russian Far East, and is similar to Mesobiotus mauccii by having an egg chorion with polygonal relief. The new species can be distinguished from M. mauccii by having a narrower buccal tube, by details of oral cavity armature, and by longer egg chorion processes. Furthermore, we provide results of the phylogenetic analyses of the genus Mesobiotus conducted in this study.
Four new species of the genus Catonidia Uhler, 1896, C. triangula sp. nov., C. saccata sp. nov., C. trilobata sp. nov. and C. uncinata sp. nov. from China (Fujian, Guizhou, Yunnan and Hainan provinces), are described and illustrated, giving the genus 14 species in total. A checklist and key to all known species of Catonidia are provided, as well as a map of their geographic distributions.

Systematics of the Sierra Nevada endemic earwig: Eulithinus analis (Forficulidae, Dermaptera)
(2024)
Since the description of Eulithinus analis (Rambur, 1838) the taxonomic position of this Sierra Nevada endemic earwig has been controversial. It has been subdivided in different taxa, assigned to various genera or transferred to different subfamilies. With the aim of clarifying its systematics, we performed a mitochondrial phylogeographic analysis using specimens from different localities of Sierra Nevada representing the diverse phenotypes treated as differentiated taxa until now, and a phylogenetic analysis including representatives of apparently distant, but morphologically close, relatives. The phylogenetic and phylogeographic results obtained using mitochondrial (cytb, cox1) and nuclear (ITS2) markers and the study of morphological characters, indicate that the Sierra Nevada Mountain Range harbors a single species of the genus Eulithinus. Based on these molecular data, the morphological characters used to date in the internal taxonomy of this group of earwigs, especially size and shape of the cerci, lack diagnostic validity and show a large inter- and intra-populational variability. These results imply the synonymy of Eulithinus montanus (Steinmann, 1981) with Eulithinus analis (Rambur, 1838) syn. nov. and the reconsideration of Eulithinus analis outside the subfamily Allodahliinae. We established the synonymy between Eulithinus analis (Rambur, 1838) and Forficula brevis Rambur, 1838 syn. nov., a name that must be removed from the synonymy of Forficula decipiens Gené, 1832.
Angel sharks (Squatina spp. Duméril, 1805) are a group of coastal benthic sharks distributed worldwide, currently including threatened and understudied species. Two species are formally described along the East Pacific coast, the California angel shark S. californica Ayres, 1859 and the Chilean angel shark S. armata (Philippi, 1887). The latter species occurs in the southeastern Pacific and has historically been understudied. Additionally, the original description of S. armata lacks sufficient data to confidently identify individuals of this species compared to modern descriptions, and no type specimen is currently available to ensure specimen identification. Detailed morphological descriptions for identifying species are an essential resource for solving taxonomic issues in groups of morphologically similar species and to promote the conservation of critically endangered species. Therefore, a neotype from the type locality is here designated for S. armata, and a detailed and standardized morphological characterization based on modern taxonomic works is provided. This work contributes in improving the knowledge on the Chilean angel shark taxonomy and provides an improved frame of reference for identifying angel sharks in the East Pacific, especially in areas where species may occur in sympatry.
In this study, I describe two new species of Macrobiotus based on morphological data collected through light and scanning electron microscopy. Both species are accompanied by DNA sequences from four commonly used molecular markers (18S rDNA, 28S rDNA, ITS-2, and COI). Macrobiotus ovovittatus sp. nov. was discovered in Greenland and can be distinguished from similar taxa of Macrobiotus by its continuous, solid, and clearly wrinkled egg surface, adorned with sparse, very small and irregularly spaced pores. Additionally, the terminal discs of egg processes are covered in multiple light-refracting dots, resembling crocheted napkins. Macrobiotus mileri sp. nov. was found in Israel and is characterized by unique pore arrangements in its body cuticle, expressed in two distinct animal forms: (i) forma porata with large pores arranged in five distinct patches and (ii) forma aporata with single, almost undetectable pores. It also features weakly defined convex terminal discs with smooth edges. Furthermore, the phylogenetic analyses conducted in this study offer the most updated phylogeny of superclade I within the family Macrobiotidae. This facilitates additional discussion concerning the interrelationships among species within the genus Macrobiotus and the circumscription of species groups within it.
The taxa of the subgenus Turritus of Cochlostoma (Cochlostomatidae) are analysed based on molecular and morphological data. The phylogenetic trees, based on ribosomal (16S) and nuclear (H3) DNA, indicate that the currently accepted taxonomy should be revised. Based on our data, there are 37 species in Turritus of which 5 are new to science: Cochlostoma (Turritus) pallgergelyi sp. nov., C. (T. ) muranyii sp. nov., C. (T. ) hallgassi sp. nov., C. (T. ) kontschani sp. nov. and C. (T. ) lacazei sp. nov. Of these, we describe the shells and the female genitalia and summarize the distributional data. Some samples (or set of samples) will remain undetermined for lack of data and these are reported in the appendix.
Sipuncula are marine unsegmented worms that can be found in benthic habitats, from shallow to deep-sea waters. In Mexico these worms have been scarcely studied. Among nine studies in the entire Mexican Pacific coasts, seven are from the central and northwestern Mexican Pacific. For over 80 years, only 24 species have been recorded. To improve the knowledge of the sipunculans from the central and northwestern Mexican Pacific, 501 specimens from three scientific collections of Mexico were revised. The specimens were collected by diverse methods from intertidal, subtidal, and bathyal depths (~1000 m), from 27 locations along the central and northwestern Mexican Pacific. Sixteen taxa belonging to nine genera and five families were identified. One species is recorded for the first time in the Mexican Pacific and five new species are described, one from intertidal and shallow subtidal depths: Phascolosoma (Phascolosoma) azteca sp. nov.; two from subtidal depths: Phascolion (Lesenka) salgadoi sp. nov. and Sipunculus (Sipunculus) bastidai sp. nov.; and two from bathyal depths: Apionsoma (Apionsoma) silviae sp. nov. and Apionsoma (Edmondsius) hendrickxi sp. nov.
