Lepidoptera

A new species of Enosis Mabille, 1889 (Lepidoptera, Hesperiidae, Hesperiinae) from southern Brazil and notes on Enosis angularis (Möschler, 1877).

A new species of Enosis Mabille, 1889 from southern Brazil, E. ester Lemes, Mielke Casagrande sp. nov, is described and illustrated. The new species is closely related to Enosis angularis (Möschler, 1877) but can be distinguishable by a set of characters on wings and male genitalia. An updated geographic distribution for E. angularis is given and illustrations of the female genitalia are provided for the first time.
Taxonomic notes on the Ectoedemia suberis and angulifasciella species groups in Japan (Lepidoptera: Nepticulidae).

Diagnoses and notes on biology and distribution of Japanese species of the suberis and angulifasciella groups of the genus Ectoedemia Busck, 1907 are given. Two species, E. chasanella Puplesis, 1984 and E. ortiva Rocienė Stonis, 2013, are reported for the first time from Japan and their morphology is redescribed. In addition, we provide molecular identification of the two species and their relatives based on COI barcode sequences and the nuclear gene (EF1-α) sequences. The female of E. chasanella is described for the first time. We confirm that E. chasanella utilizes Quercus species (Fagaceae) as its hostplant: Q. dentata, Q. serrata, Q. crispula, and Q. acutissima. Ectoedemia ortiva was formerly placed in the suberis group, and its host plant was unknown. We move this species to the angulifasciella group and provide evidence that it utilizes Ulmus sp. (Ulmaceae) as its host plant.
A new Euchalcia Hübner, [1821] from Qinghai, China (Lepidoptera: Noctuidae.

The Palaearctic genus Euchalcia Hübner, [1821] is a member of the subfamily Plusiinae, family Noctuidae. Currently it includes 53 valid species and 6 subspecies (Ronkay et al. 2008; Volynkin et al. 2014). The E. gerda species-group includes E. gerda (Püngeler, 1907), E. caelestissima Hreblay Ronkay, 1998, E. serraticornis Dufay, 1965 and E. bea Hreblay Plante, 1998 (Ronkay et al. 2008). During examination of more than 80 specimens identified as E. gerda collected in several localities in the Chinese province of Qinghai and deposited in the collections of Péter Gyulai (Miskolc, Hungary), Alessandro Floriani (Milan, Italy) and World Insect Gallery (Joniškis, Lithuania), we found two strange looking specimens having more elongated forewings with a well-developed pinkish suffusion. Despite the wide range of an individual variability being characteristic for species of the E. gerda species-group, these two specimens showed morphological differences from E. gerda as well as from other related species, and thus proved to be new for science. The description of this new species is given below.


A large hornet mimic clearwing moth of the genus Lamellisphecia Kallies amp; Arita, 2004 (Lepidoptera, Sesiidae) from Nanling, Guangdong, southern China.

We here describe a new species, Lamellisphecia minwangi Arita Kallies sp. nov., from Nanling, Guangdong, southern China. Furthermore, we provide new records of Lemellisphecia Kallies Arita, 2004 species from south-east Asia, with L. champaensis Kallies Arita, 2004 recorded for Laos and L. haematinea Kallies Arita, 2004 recorded for Myanmar for the first time.
A DNA-based description of a new carpenter moth species (Lepidoptera: Cossidae) from Morocco.

We used a combination of morphological data (genitalia structure) and a molecular marker (a 658bp fragment of the COI gene) to demonstrate that carpenter moth populations from central and southern Morocco, previously identified as Cossus cossus (Linnaeus, 1758) based on external morphology, represent a new species, described herein as C. romantsovi Yakovlev Shapoval, sp. n. The genetic divergence of the new species with respect to other members of genus Cossus is significant and includes at least 23 fixed nucleotide substitutions in the 658 bp of the COI barcode.

Contribution to the knowledge on the genus Barsine Walker, 1854 from mainland China and Indochina, with description of a new species (Lepidoptera, Erebidae, Arctiinae, Lithosiini).

A new species of the genus Barsine, viz. Barsine fangchenglaiae Huang, Volynkin, Černý Wang sp. nov. from SW China, N Thailand and N Vietnam is described. The following six taxa are confirmed as new records to China: B. pretiosa Moore, 1879, B. defecta defecta Walker, 1854, B. gratissima (de Joannis, 1930), B. flammealis Moore, 1878, B. mactans Butler, 1877 and Barsine vinhphucensis Spitsyn et al., 2018. The new synonymy is established: Barsine pretiosa Moore, 1879 = Barsine pseudomactans Volynkin Černý, 2016, syn. nov. Adults and genitalia of all species aforementioned are illustrated.


Coccygidium transcaspicum (Kokujev) (Hymenoptera: Braconidae) parasitizing larvae of invasive pest Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) in India.

The parasitoid Coccygidium transcaspicum (Kokujev) (Hymenoptera: Braconidae: Agathidinae) was reared from fall armyworm or Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) in maize fields in South India (Telangana) during 2019. It is the first report of a host for C. transcaspicum and the first report of C. transcaspicum as a parasitoid of S. frugiperda across the globe. The present study contains the first report from India and the Oriental region, provides morphological identification details of C. transcaspicum and comparison notes from its closely allied species C. melleum (Roman) which is basically an Afrotropical species.


A review of the genus Evonima Walker, 1865 from China with description of a new species (Lepidoptera, Nolidae, Nolinae).

Ten Chinese species of the genus Evonima Walker, 1865 are reviewed. A new species (Evonima tianmuensis sp. nov.) is described from Tianmushan Mt., Prov. Zhejiang. Adult and distribution of each species from China are illustrated. A key to species of the genus from China is provided.
Victrix svetlanae sp. n., a new species of Bryophilinae (Lepidoptera, Noctuidae) from Far East of Russia.

Victrix svetlanae sp. n. is described from Russian Far East, Khabarovsk Krai. The new species belongs to the subgenus Poliobrya Hampson, 1908. New species is most similar to V. umovii (Eversmann, 1846) and V. patula (Püngeler, 1907) but differs in both external and genital characteristics. This is the first record of the genus Victrix in the Far East.

A key to the Chinese species of the genus Diduga, with illustrations of adults and genitalia of examined species are presented.


Wrong side of the leaf: assigning some Lithocolletinae species (Lepidoptera: Gracillariidae) to their proper genera.

Cameraria Chapman and Phyllonorycter Hübner (Gracillariidae: Lithocolletinae) are two speciose genera of leaf-mining moths that were once treated as belonging to a single genus, Lithocolletis Hübner. Typically, species of Cameraria form flat mines on the upper leaf surface, whereas most Phyllonorycter species form underside tentiform mines. We reviewed North American literature records and found 15 exceptions to this generalization, with two Cameraria species reported to form underside mines and 13 Phyllonorycter species reported to form upper-surface mines. For each of these species we summarize the published data on larval biology, hostplants, and distribution, which we supplement with internet records and our own observations. Both purported Cameraria species making underside mines were misplaced in this genus by Davis (1983); we affirm the combinations Phyllonorycter affinis (Frey Boll) and P. leucothorax (Walsingham), each of which has been published once before but not formally proposed as a new combination, and thus has been ignored by subsequent authors. We have further determined P. affinis to be a junior synonym of P. mariaeella (Chambers). Three of the purported Phyllonorycter species making upper-surface mines were similarly misplaced. One of these, Anarsioses aberrans (Braun), has recently been transferred to a new genus, and we propose the new combinations Cameraria arizonella (Braun) and C. cretaceella (Braun) for the other two. Genitalia and forewing patterns are illustrated for all species whose generic placement is corrected in this paper.


Hidden Genetic Variability, Can the Olive Moth Prays oleae (Lepidoptera: Yponomeutidae or Praydidae?) be a Species’ Complex?

Prays oleae is the second most important pest in Mediterranean olive groves, causing substantial damage on olive production. We used mitochondrial [cytochrome c oxidase subunit I (COI), and NADH dehydrogenase subunit 5 (nad5)] and nuclear [ribosomal protein S5 (RpS5)] amplicons to assess the population variability in five main olive producing regions from Tunisia, to support or dismiss the existence of two non-monophyletic groups within the species, as found within Portugal. Our phylogenetic analysis with cytochrome c oxidase subunit I (COI) indeed displayed two distinct and well-supported clades of P. oleae, which were corroborated by the haplotype network reconstructed with both mitochondrial and nuclear amplicons. We were also able to dismiss the hypothesis that one of the clades would not develop on olive fruits. No correlation was observed between clades differentiation and geographic distribution. The existence of cryptic species can impact on the management of agroecosystems and on the perception of how these moths responds to environmental changes.


Mating Disruption of Helicoverpa armigera (Lepidoptera: Noctuidae) on Processing Tomato: First Applications in Northern Italy.

Helicoverpa armigera is a polyphagous and globally distributed pest. In Italy, this species causes severe damage on processing tomato. We compared the efficacy of mating disruption with a standard integrated pest management strategy (IPM) in a two-year experiment carried out in Northern Italy. Mating disruption registered a very high suppression of male captures (>95%) in both growing seasons. Geostatistical analysis of trap catches was shown to be a useful tool to estimate the efficacy of the techniqu
