Two new species of the genus Klimeschiopsis Povolny, 1967 from southern Siberia discovered as a result of study cryptic diversity in K. discontinuella (Rebel, 1899) (Lepidoptera: Gelechiidae)

Klimeschiopsis varia Sumpich & Bidzilya, sp. n. and Klimeschiopsis confusella Sumpich & Bidzilya, sp. n. are described as new species for science based on differences from congeners in external appearance, genitalia of both sexes and genetic data. Klimeschiopsis varia is most similar to Klimeschiopsis discontinuella (Rebel, 1899) and Klimeschiopsis maritimaealpina Nel & Varenne, 2011 but can be distinguished by the genitalia characters. Klimeschiopsis confusella resembles Klimeschiopsis kiningerella (Duponchel, [1843]) and Klimeschiopsis terroris (Hartig, 1938) by absence of yellowish suffusion on forewings, but the coloration of new species is not so much contrasting, and the species is unmistakable according to the genitalia. Both new species occur sympatricaly in Russian Altai Mountains, Tuva and Buryatia.

Oligophlebia hibiscivora sp. nov., a new species from south-eastern China (Lepidoptera, Sesiidae)

A new species, Oligophlebia hibiscivora Yu, Kallies & Arita sp. nov., is described from south-eastern China. Superficially, it is similar to Oligophlebia insurgia Kallies, 2020 but it differs by external features of the abdomen as well as the male genitalia characters. The larva of this new species feed in Hibiscus tiliaceus L. (Malvaceae) and was found in the urban area of Xiamen (Fujian Province) and in Hongkong. Images of male and female specimens, genitalia and pupa of the new species are provided as well as the image of the female genitalia of Oligophlebia minor Xu & Arita, 2014. An updated catalogue of the species of the genus Oligophlebia Hampson, 1893 and a key of Chinese species are provided.

First report of Garella musculana (Erschov, 1874) (Lepidoptera: Nolidae) in Italy with insights into its identity

AbstractThe Asian walnut moth, Garella musculana (Erschov, 1874) (Lepidoptera: Nolidae), is a major pest of walnut. Native to Central Asia, it was found to be invasive in 2008 in Sevastopol (Crimea) and nowadays widespread in Turkey, Bulgaria, Romania and Russia. Here, we account for the finding of G. musculana in NE Italy (Veneto region) in 2021, where adults were found in a light lamp, representing the first record of the Asian walnut moth for this country and Western Europe. Adult specimens were identified morphologically on both external characters and genitalia features. G. musculana larvae and damage were also observed on a plantation of Juglans regia L. (Fagales: Juglandaceae) located in Veneto in October 2021. A COI‐barcoding analysis was performed to attain a molecular characterization of our specimens and probate our morphological identification. However, because no sequence of G. musculana was present in major gene databases and the similarity of our sequences with those attributed to Garella ruficirra (Hampson, 1905) (Lepidoptera: Nolidae) made clear that these taxa deserved further scrutiny regarding their specific distinction. Some subtle differences in the male terminalia could be found between them and their vast geographic distributions, but the strong similarity in most features calls for further morphological and genetical insights on a broad set of samples to assess whether they represent two closely related, substantially parapatric species, or a unique, geographically varying entity. Solving this issue may turn out crucial in the identification and proper management of walnut moths of the genus Garella.

Early stage of evolution of Gonomyia (Diptera: Limoniidae), new significant discoveries in the Cretaceous Iberian and Kachin amber

New Complex of Cryptic Species Discovered in Genus Biblis (Papilionoidea: Nymphalidae: Biblidinae) in Mexico.

Our research focuses on demonstrating the existence of cryptic species named under Biblis aganisa Boisduval.We used COI sequences to delimit Biblis species for Mexico using species delimitation analyses and examined phylogenetic relationships with sequences from Mexico, Costa Rica, Argentina, USA, and Guana Island using a Bayesian inference tree. We performed a discriminant analysis with quantitative traits using female and male wing and genitalia, and a tree of maximum parsimony based on 39 qualitative characters of wings, head, and male genitalia. The results were congruent in the three analyses. Three groups were formed based on DNA, ECO 01 + DHJ02, ECO 02 + DHJ01, and ECO 03. The characters that contributed over 50% separation were for wings: wing length, anal margin length, and distance from the band to the outer margin; for male genitalia, angle of the integument, uncus, and the length of the hypandrium, while for females, it was the angle of the anteapophysis and the length of the abdomen. For the analysis of qualitative characters, a tree of maximum parsimony was obtained where 20 characters were informative. We confirmed the existence of three cryptic Biblis species in Mexico, two not yet described, and one corresponding to B. aganisa (ECO 02), which is sympatric in Oaxaca and Sinaloa (ECO 03) and in the Yucatan Peninsula (ECO 01).

A new species and new records of Gnorimoschemini (Lepidoptera, Gelechiidae) from Ecuador.

Scrobipalpula onorei sp. nov. is described from Las Pampas, Ecuador.

New and little known taxa of the genera Gymnogryllus and Macrogryllus (Orthoptera: Gryllidae: Gryllinae) from Indo-Malayan and Papuan Regions

A new material on the genera Gymnogryllus Sauss. and Macrogryllus Sauss. is considered. Three new taxa from the Indo-Malayan and Papuan Regions are described: G. egorovi sp. nov. (Indonesia: Maluku Utara Province); G. vietnamensis mada subsp. nov. (Vietnam: Dong Nai Province); M. canorus sp. nov. (Malaysia: Pahang State). The first species is distinguished from all the other congeners by a few distinct features of the male tegminal venation and some important characters of the male genitalia; the second new taxon differs from the nominotypical subspecies of the same species almost only in small details of the male genitalia; and M. canorus sp. nov. is different from the only other species of Macrogryllus mainly in the male genitalia with a very characteristic shape of the ectoparameres. The male genitalia of M. ephippium ephippium (Saussure, 1877) are firstly examined, and previously unknown male of M. bicolor Chopard, 1930 is also described; for the both latter taxa, some new localities are recorded; and for M. bicolor, its calling burrow is firstly found (this burrow is very characteristic, in the shape of a ground cone with an almost vertical tunnel leading to the underground cavity, where the male is hiding during its calling song).

Rediscovery of the myrmecophilous Lucanid genus Xizangia Zhang, 1988 from southwest China (Coleoptera: Scarabaeoidea: Lucanidae).

The unexpected rediscovery of the long-lost Penichrolucanini genus Xizangia Zhang, 1988 from China reveals the ant-association of the genus, unlike the termite-association of other Penichrolucanini species from SE Asia. The newly discovered populations of Xizangia from W and S Yunnan belong to a second species of the genus: Xizangia qiuae Huang Chen, new species. Biological observations are given. Adult morphology including mouthparts, hindwing, male and female genitalia and larval morphology are described in detail for the new species. Brasilucanus alvarengai Vulcano Pereira, 1961 and Penichrolucanus copricephalus Deyrolle, 1863 are figured in previously undescribed characters of mouthparts, hindwing and female genitalia. The current state of Penichrolucanini systematics is discussed.

Potamophylax idliri sp. nov. (Trichoptera: Limnephilidae), a new species from the Jastrebac Mountains in Serbia, with molecular and ecological notes.

In this paper, we describe a new species, Potamophylax idliri sp. nov., from the Jastrebac Mountains in Serbia, which is morphologically most similar to Potamophylax coronavirus Ibrahimi, Bilalli Vitecek 2021 (in Ibrahimi et al. 2021) and Potamophylax juliani Kumanski 1999 (in Kumanski Malicky 1999). The males of the new species differ from all known species of the Potamophylax winneguthi Species Group by morphological characters of the male genitalia. The genetic distinctiveness calculated based on sequencing of the barcode region of the cytochrome c oxidase subunit I gene (COI) between Potamophylax idliri sp. nov. and other species of the Potamophylax winneguthi Species Group is on par with those of other morphologically recognized species in the group and especially the other four species of the P. winneguthi Species Cluster. Potamophylax winneguthi Species Cluster is erected for the following species: P. idliri sp. nov., P. winneguthi, P. haidukorum Malicky 1999 (in Kumanski Malicky 1999), P. juliani, and P. coronavirus, characterized primarily by the bilobed apical margins of inferior appendages with pointed corners, in lateral and caudal views. The new species was found at two localities in the Jastrebac Mountains, at 988 and 891 m above sea level. Considering the knowledge about distribution and ecology of the other species of this group, we posit that P. idliri sp. nov. is a microendemic of the Jastrebac Mountains in Serbia.

Processuridia, a new genus for two new species from China and Indochina (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

A new Nudariina genus, Processuridia S.-Y. Huang Volynkin gen. n. is erected for two new species described herein: Processuridia thangka S.-Y. Huang Volynkin sp. n. from southeastern Xizang, southwestern China and P. oreas Volynkin S.-Y. Huang sp. n. from southeastern Yunnan, southwestern China and Mt. Fansipan, northern Vietnam, with P. thangka sp. n. as the type species of the genus. Based on molecular phylogenetic analysis, the new genus is found to be sister to the clade (Asuridia Hampson + Disasuridia Fang), but it can be easily distinguished from both genera by the unique wing pattern and genitalia features. Adults and genitalia of the aforementioned taxa are illustrated.
