Abstract

Saridoscelis Meyrick, 1894 belongs to Yponomeutidae, with 9 described species. A new species, Saridoscelis diffusolinearum Lu & Hsu, sp. nov., is described from Taiwan, with diagnostic characters provided for both sexes herein. We also proposed that S. diffusolinearum sp. nov. is close related to S. kodamai Moriuti, 1961. The new species feeds on a subalpine bush Gaultheria cumingiana Vidal (Ericaceae) further indicating that the host plant of the subfamily Saridoscelinae may restricted to Ericaceae.

Saridoscelis diffusolinearum Lu & Hsu, sp. nov.

臺灣散紋燕白巢蛾

Diagnosis: This new species is similar to Saridoscelis kodamai Moriuti, 1961, both in external features and genitalia. The forewing upperside of S. diffusolinearum sp. nov. is dusted with gray scalings, decorated with a dark gray streak. By contrast, that of S. kodamai is without gray, with streaks paler in coloration. In male genitalia, the valva of S. diffusolinearum sp. nov. does not possess a medial hump found in S. kodamai, with the gnathos of the former longer than the latter. ...

Etymology: The name is a combination of two Latin wards diffusa and linea, meaning spread out and line respectively, because of the diffused, inconspicuous grey and ocherous scales overlaid on forewing uppersides, with presence of prominent dark streaks.

[Entomology • 2023] Rediscovering A Species not seen for a Hundred Years, Stathmopoda tacita (Meyrick, 1913) (Lepidoptera: Stathmopodidae), with its unusual Fern-spore-feeding Life History

Stathmopoda tacita (Meyrick, 1913)

in Shen et Hsu, 2023.

DOI: 10.3897/BDJ.11.e101468

Abstract

Background:

Despite being the second largest group of vascular plants, ferns are scarcely reported being fed by insects when compared to angiosperms. Within these fern-feeding insects, lepidopterans are poorly represented and are restricted only to specific groups in this speciose order. The consumers specialising on fern spores are even scarcer in the order, with the majority being consumers of vegetative structures. Amongst the fern-spore-feeding Lepidoptera, Stathmopodidae is the family with the highest species diversity, even with a subfamily, Cyprininae Sinev, 2015, specialising on fern spores. However, fern-spore-feeding habit is not restricted to this subfamily. To understand the evolution of fern-spore-feeding within this family and to increase our knowledge of insect-fern evolution, detailed studies on fern-spore feeding stathmopodids are essential.

New information:

The present study rediscovered a rare, fern-spore-feeding, stathmopodid micro-moth, Stathmopoda tacita (Meyrick, 1913), which has not been formally recorded or identified for more than 100 years. We documented the life history of this species and identified several species of Pyrrosia (Polypodiaceae, Platycerioideae) as host for the moth’s larvae. A re-description of the fern-feeding moth is also provided as the original description is obscure in terms of character diagnosis.

Stathmopoda tacita (Meyrick, 1913)

Diagnosis:

Stathmopoda tacita is similar to S. masinissa Meyrick, 1906 and S. maritimicola Terada & Sakamaki, 2011 (see Terada et al. (2011)), but can be distinguished from these two species by the colour and shape of fascia near apex of forewing. The fascia is oval, ochrous in colour in female and vestigial in male in S. tacita, whereas the fascia is creamy-white in colour and triangular in both sexes of S. masinissa. For S. maritimicola, the fascia is triangular, yellow in colour in both sexes and sometimes vestigial in male.

In genitalia, these species can be distinguished by the presence of cervix bursae. Cervix bursae are absent in S. tacita, but well-developed in the other two species.

[Entomology • 2020] Incurvaria pirinella • A New Species of the vetulella species-group (Lepidoptera, Incurvariidae) from Bulgaria, with release of DNA Barcodes for European Species of Incurvaria

[3-5] Incurvaria pirinella Junnilainen, Kaitila & Mutanen, 2020

[14] Incurvaria circulella (Zetterstedt, 1839)

in Junnilainen, Buchner, Kaitila & Mutanen, 2020.

DOI: 10.3897/nl.42.13026

Abstract

Incurvaria pirinella Junnilainen, Kaitila & Mutanen, sp. nov. is described from Bulgaria based on specimens collected by netting and artificial light from several low-elevation localities in Bulgaria. The species is morphologically and genetically most similar to I. triglavensis Hauder, 1912. Differences between these two species are present in external appearance and genitalia of both sexes. Additionally, I. pirinella shows a distance of 4.74% to its nearest neighbour I. triglavensis in the standard DNA barcoding marker (COI-5P). We provide preliminary observations of phylogenetic affinities of European Incurvaria and briefly discuss habitat preferences of some species. All species have distinct barcodes with minimum K2P divergences between species averaging 7.05% (range 1.2–12.8%). A world checklist of Incurvaria Haworth, 1828 is provided and DNA barcodes for all European species are here released. Finally, we document morphological variation in male genitalia within I. triglavensis Hauder, 1912.

Incurvaria pirinella Junnilainen, Kaitila & Mutanen, sp. nov.

Etymology: The name of the new species is derived from the Pirin mountain range, where the new species is widely distributed.

Diagnosis:

Considering similar forewing ground colour and markings, Incurvaria pirinella (Figs 3–5) is externally closest to I. circulella (Fig. 14), but is easy to separate from it by the dark grey-brown fringe and distinct white spot in the forewing fringe present in I. circulella. Incurvaria pirinella is also widely allopatric as I. circulella occurs only in northern latitudes in Europe, e.g. the northern part of Sweden and Finland.

Although I. triglavensis is rather variable externally, it is always easy to separate from I. pirinella based on its relatively narrow forewing shape, paler ground colour and differences in forewing markings (Figs 6–11); see details in Suppl. material 2.

Incurvaria pirinella is easy to separate externally from Scandinavian I. vetulella (Figs 12–13) by a white narrow dorsal spot situated 2/5 from base and extending more than halfway across the forewing in I. pirinella. North European I. vetulella also typically have a distinctly broader dorsal spot, sparser forewing scaling and usually a pale medial area in the fringe, which is always absent in I. pirinella.

...

Distribution: Known from four different localities in the south-west corner of Bulgaria around the Struma river valley and its adjacent regions, which all belong to the Blagoevgrad district and the Pirin mountain range. The elevational range is wide: 200–1200 m, at least.

Abstract

The monotypic genus Neopalpa was described in 1998 by Czech entomologist Dalibor Povolný based on two male specimens from Santa Catalina Island, California, which he named N. neonata. The female of this species was discovered recently based on a DNA barcode match and is described. In addition, a new species with marked differences in morphology and DNA barcodes from southern California and Baja California Mexico is described as Neopalpa donaldtrumpi sp. n. Adults and genitalia of both species are illustrated, new diagnosis for the genus Neopalpa is provided, and its position within Gelechiidae is briefly discussed.

Etymology: The new species is named in honor of Donald J. Trump, to be installed as the 45th President of the United States on January 20, 2017. The reason for this choice of name is to bring wider public attention to the need to continue protecting fragile habitats in the US that still contain many undescribed species. The specific epithet is selected because of the resemblance of the scales on the frons (head) of the moth to Mr. Trump’s hairstyle. The name is a noun in the genitive case.

Distribution: So far only known from Riverside and Imperial counties in southern California and Baja California in Mexico.

Biology: Specimens collected at mercury-vapour light, black-light or Malaise trap in February, April, June and August, in dry or sandy habitats. Life history and host plant unknown.
