**Phenotypes, natural history and barcodes unveil cryptic species within the Caribbean Metalmark Dianesia carteri (Holland) (Lepidoptera: Riodinidae)**

Tue, 26 Aug 2025 00:00:00 +1200

The butterfly genus Dianesia Harvey & Clench, 1980 is the only known representative of the family Riodinidae in the West Indies with a single described species containing two subspecies, represented by rare, little-known populations occurring only in the Bahamas and Cuba. Until now, the genus has been regarded as monotypic, but differences in morphology, DNA barcodes and life history suggest that it contains multiple cryptic species. Our assessment led to recognize the existence of at least nine species within Dianesia: Dianesia carteri (Holland, 1902), Dianesia ramsdeni (Skinner, 1912) (previously regarded as a subspecies of the first), Dianesia galindoensis Barro, Hernández & Torres, 2025, and the newly herein described Dianesia aberrans sp. nov., Dianesia sheylae sp. nov., Dianesia alayoi sp. nov., Dianesia flammata sp. nov., Dianesia abscondita sp. nov. and Dianesia serpentinicola sp. nov. These species remained unnoticed due to their superficial resemblance and lack of information about their biology, but can be differentiated by a combination of their DNA barcodes, wing length and shape, and elements of the color pattern, particularly the forewing postdiscal white band. Genitalia, habitat, host plant, and larval morphology also serve to differentiate the species. Bayesian and maximum likelihood COI gene trees recovered a similar topology in which all species are reciprocally monophyletic except for D. alayoi nested inside D. flammata. Species delimitation analyses supported the described species, including those that are not monophyletic, and suggested the presence of three additional species, but we regard them as artifacts produced by specimens with slightly different barcodes. Future research employing more genetic and ecological data is necessary to clarify the relationships among these species, as well as to understand their biogeographical history, ecology, and behavior, and to provide baseline knowledge for their conservation.

**Taxonomic and faunistic comments on European Parydra Stenhammar, 1844 (Diptera: Ephydridae) with new species from Finland and Jordan**

JENS-HERMANN STUKE — Tue, 26 Aug 2025 00:00:00 +1200

Parydra hautalai spec. nov. (Finland), Parydra kahanpaai spec. nov. (Finland) and Parydra cryptica spec. nov. (Jordan) are described. Four new synonyms are proposed: Parydra stagnicola (Robineau-Desvoidy, 1830) = Parydra coarctata (Fallén, 1813) (syn. nov.), Parydra danensis Stuke 2012 = Parydra flavitarsis (Dahl, 1964) (syn. nov.) and Parydra ralloi Canzoneri & Meneghini 1978 = Parydra albifacies (Duda 1942) = Parydra hecate (Haliday, 1833) (syn. nov.). A new subgenus position is proposed for Parydra (Chaetoapnaea) flavitarsis (Dahl, 1964), Parydra (Chaetoapnaea) nubecula Becker, 1896, Parydra (Chaetoapnaea) quinquemaculata Becker, 1896 and Parydra (Chaetoapnaea) undulata Becker, 1896. Parydra unicolor (Becker, 1926) is treated as a nomen dubium. A lectotype is designated for Parydra nigritarsis Strobl, 1893. Parydra articulata Canzoneri & Meneghini is reported from Europe for the first time. New faunistic country records are listed from Croatia, Cyprus, France, Georgia, Greece, Jordan, Kyrgyzstan, Morocco and Portugal (Madeira). A key to European Parydra species is presented. Illustrations are provided of the habitus and male terminalia for most European Parydra species. All European Parydra species are listed with their synonyms. A short diagnosis and summaries of the European distribution and known biology are also presented for all European Parydra species.

**Completing the fantastic quartet of Bennarellini in Brazil: First record and description of a new species of Noabennarella Holzinger & Kunz, 2006 (Hemiptera: Fulgoromorpha: Cixiidae)**

EDUARDA FERNANDA GOMES VIEGAS, ROSALY ALE-ROCHA — Tue, 26 Aug 2025 00:00:00 +1200

The third species of Noabennarella Holzinger & Kunz is described, Noabennarella franciscoi sp. nov., and represents the first record of the genus for Brazil. A key to genera and species of Bennarellini is provided.

New solenofilomorphids (Solenofilomorphidae: Acoela) from the northwest Atlantic

MATTHEW D. HOOGE, CHRISTIANE TODT, SETH TYLER — Tue, 26 Aug 2025 00:00:00 +1200

Myopea calleum sp. nov. and Solenofilomorpha crezeei sp. nov. are newly discovered species of interstitial acoels and the first species of the acoel family Solenofilomorphidae to be described from the NW Atlantic. Both species have rather robust reproductive organs compared to their congeners. M. calleum sp. nov. is distinctive for its prominently glandular penis encompassed in an elongate, thick-walled seminal vesicle readily visible in squeeze preparations, as well as for its red coloration and lateral chordoid tissue. S. crezeei sp. nov. is similarly distinct from other species of Solenofilomorpha in having a more muscular, thick-walled seminal vesicle and thick, muscular sheath enclosing both seminal vesicle and penis, but also in having a sclerotized cone capping the penis. The cone is formed by converging necks of actin-rich cells encircling the muscular sheath where it joins the antrum.

Sophronia pseudosagittans sp. nov. (Lepidoptera, Gelechiidae), a new species from the Iberian Peninsula and Tunisia

OLEKSIY V. BIDZILYA, OLE KARSHOLT, JAN ŠUMPICH — Tue, 26 Aug 2025 00:00:00 +1200

Sophronia pseudosagittans sp. nov. is described from Portugal, Spain and Tunisia. The morphological and molecular differences between the new species and the closely related S. sagittans Meyrick, 1923 and S. humerella ([Denis & Schiffermüller], 1775) are discussed. Adults and the male and female genitalia of the newly described and related species of Sophronia are illustrated.

**A new Orzolina Machado, 1987, from the Canary Islands (Coleoptera: Carabidae: Bembidiinae)**

ANTONIO MACHADO — Tue, 26 Aug 2025 00:00:00 +1200

Orzolina kratkyi sp. nov. is described from the island of Tenerife, in the Canarian archipelago. This endemic genus was known before from a single species in the eastern islands, Orzolina thalassophila. Both species live similarly, on the intertidal zone and are covered by the sea at full tide. A description and images of the imago and aedeagus are provided. The new species is characterized by its smaller size, more transverse pronotum and uniformly oval elytra. The mtCOI genetic distance between both species is 12.8%.

**Description of the males of Glolarnaca flata Luo, Zhang & Bian, 2024 and Glolarnaca carinata Pang & Bian, 2023 for the first time (Gryllacrididae)**

WENQING LV, BINGYU REN, FUMING SHI — Tue, 26 Aug 2025 00:00:00 +1200

This paper describes the males of Glolarnaca flata Luo, Zhang & Bian, 2024 and Glolarnaca carinata Pang & Bian, 2023 for the first time. The species occur in Yunnan, China. Morphological illustrations of examined specimens are provided.
