A group of 15 species from the genus Euphylidorea (Alexander, 1972) is identified based on distinct morphology and described as the new subgenus Neophylidorea. Characters of the aedeagus and male genitalia in general allow for unequivocal recognition of this subgenus. Comparisons among other species-groups within Euphylidorea and Neophylidorea subgen. n. Petersen are made. A new species, Neophylidorea vannimwegeni Petersen is described based on two male specimens collected in Michigan, USA. This species can be distinguished by the unique structure of the ventral parameres in the male hypopygium.

Dichagyris is a diverse genus with a Holarctic distribution. Only a few taxa of the subgenus Albocosta Fibiger & Lafontaine, 1997 occur in the northwesternmost part of the Oriental region. The genus is most diverse in Turkey, Iran and the Central Asiatic high mountains. However, there is a distinct Sino-Tibetan group of species, possibly representing an undescribed subgenus. However, this idea is provisional and awaits revision of the genus. For present purposes, we assign these species to the subgenus Dichagyris. They share the following putative synapomorphies: black, dark brown or dark greyish forewing ground colour (with one exception), with obscure, reduced wing pattern and a broad-based, short, conical harpe in the male genitalia. Species of this group can be subdivided to two species-groups. In the astigmata-group which was mentioned for the first time by Hreblay et al. (1998) but without description or diagnosis from the minuta-group, the vesica is elongate and tubular (males), the appendix bursae and corpus bursae are long, sack–like, almost equal in size (females). In the minuta-group, the vesica is more ample than in the astigmata-group, and coiled, and the appendix bursae is globular and much shorter than the corpus bursae. The astigmata-group includes Dichagyris astigmata (Hampson, 1906), D. gansuensis Hreblay & Ronkay, 1998, D. geochroides (Boursin, 1948) and D. vargazoli (Gyulai & Ronkay, 2001). The minuta-group comprises D. minuta Hreblay & Plante, 1998 and D. kormos Gyulai & Ronkay, 2001. During a research expedition in Sichuan in 2019, the existence of a third species in the minuta-group was recognized, which is described here. In addition, the female and its genitalia of D. gansuensis, which was described by Hreblay & Ronkay (1998) based on a single male, are illustrated here for the first time.

AbstractA new species of Forcipomyia from Singapore is described in all stages. Although the female adult could be placed in Lepidohelea Kieffer (1917) by the possession of scales in addition to bristles and hairs, the male genitalia are distinctive. A new subgenus, Schizoforcipomyia, is erected to accommodate this species whose larva has a bilobed anal pseudopod and whose male genitalia are intermediate between Forcipomyia s. str. and Proforcipomyia.

The Afrotropical genus Pegylis Erichson, 1847 (Coleoptera: Scarabaeidae: Melolonthinae: Pegylini) was recently treated by Lacroix (2015), who keyed and figured most of the known species and divided the genus into six species groups based on the number of antennomeres, shape of male genitalia and number of teeth on the protibia. Unfortunately, Lacroix (2015) overlooked two earlier papers by Harrison (2014a, 2014b). Harrison (2014a, 2014b) provided a phylogenetic analysis of the tribe, synonymised Hypopholis Erichson, 1847 with Pegylis, and redescribed the three known South African species of Pegylis. Based on these papers, the genus Pegylis currently contains 37 species.

The discovery of a new species of satyrine butterfly, Magneuptychia louisammour Benmesbah & Zacca, sp. n., that is phenotypically similar to a sympatric species widely known as Magneuptychia ocypete (Fabricius, 1776), led to a review of the taxonomic status of M. ocypete. A neotype for Papilio ocypete Fabricius, 1776 is designated and its redescription is provided. Neonympha sabina C. Felder & R. Felder, 1867 and Euptychia helle var. olivacea Aurivillius, 1929 are treated as junior subjective synonyms of P. ocypete and a lectotype is designated for each name. A neotype for the preoccupied name Papilio helle Cramer, 1779, and its replacement name Magneuptychia fugitiva Lamas, [1997], is also designated, and a redescription of this name and discussion of its taxonomic status are provided. We describe an additional phenotypically similar species, Magneuptychia kamel Benmesbah & Zacca, sp. n. from the western Amazon and raise the name Magneuptychia opima sheba Brévignon & Benmesbah, 2012 to species rank (stat. rev.) on the basis of morphological and DNA sequence evidence. We also discuss the difficulties regarding taxonomic and geographical delimitation in these complex species groups. Observations on Euptychiina behaviour are also provided. Finally, based on external characters and male genitalia, a proposed preliminary arrangement of two species groups is proposed, including other species of Magneuptychia Forster, 1964 and Cissia Doubleday, 1848.

In this paper we describe the new subgenus Baeticoharpalus Serrano & Lencina and a new species Harpalus (Baeticoharpalus) lopezi Serrano & Lencina, based on a unique character combination that includes the pubescence of temples, frons, pronotum and elytra, the lack of mentum tooth, the shape of mouth parts and the male genitalia. The new taxon was collected in Sierra Morena (Pico de Almadén, central Betic Mountains, south Spain) and is geographically isolated from related taxa. Distribution data suggest that this is a relict species. The taxonomic position of the new taxon is discussed in relation to the other Iberian subgenera of Harpalus and the related genera Pangus, Pseudoophonus, Ophonus, etc. A key to Iberian Harpalus and related taxa is included; it illustrates the abundance of homoplasic characters within these taxa and the difficulties to develop a ‘natural’ key for identifying them.

During a DNA barcoding campaign of leaf-mining Gracillariidae from the Asian part of Russia, a new species ofPhyllonorycterHübner, feeding on the Siberian pea shrub,CaraganaarborescensLam. (Fabaceae) was discovered in Siberia. Here, this taxon is described asPhyllonorycterivanisp. n.Among Fabaceae-feedingPhyllonorycter, so far onlyP.caraganella(Ermolaev) has been known to develop onCaragana.PhyllonorycterivaniandP.caraganellashow a large divergence in morphology (external and male genitalia) and barcode region of the mtDNA-COI gene (8.6%). They feed on different host plants species and have different ranges in Russia. We show that DNA barcode data weakly supports the Fabaceae-feeding species groups. In addition, we show that morphologically (strongly) and genetically (weakly),P.ivanihas affinity to thehaasispecies group, a West Palearctic group with asymmetrical male genitalia.

A new species of the genus Neopseustis Meyrick, 1909, Neopseustis chentangensis S.Y. Huang & Chen sp. nov., which was confirmed by both morphological and molecular methods, is described from Xizang, China. This is currently the westernmost species in Asia of the primitive lepidopteran family Neopseustidae. The new species is externally reminiscent of N. moxiensis Chen & Owada, 2009; however, it can be easily distinguished from the latter by comparison of the male genitalia and is further distinguished by the large genetic distance in DNA barcodes (COI). The adult and genitalia of the new and similar species have been illustrated. Utilizing our new data, a new classification of the genus is provided, with its members subdivided into four species groups: the meyricki-group, the moxiensis-group, the bicornuta-group, and the chentangensis-group, which are supported by both molecular and morphological evidence. A checklist of the genus and a key to the species groups are also provided.

Two new species-groups of the cantharid genus Stenothmeus Bourgeois are defined, S. laterophysus species-group and S. notaticollis species-group. The S. laterophysus species-group is composed of two species, including S. laterophysus Švihla, 2004 and a new species, S. nigritibius Y. Yang et H. Liu, sp. nov., and characterized by the pitch black elytra and bicolored legs, the subrounded pronotum with widely rounded anterior angles and projecting posterior angles, male genitalia with slender ventral processes of parameres which are slightly bent inwards at apical parts, laterophyses tilting ventrally at an angle of more than 45° with dorsal plates, compressed at apical parts, as well as the slender spermathecal duct, extremely long spermatheca and diverticulum. The S. notaticollis species-group consists of five species, including S. notaticollis (Gorham, 1895), S. bourgeoisi Wittmer, 1974, S. tamil Švihla, 2011 and two new species, S. parameratus Y. Yang et S. Ge, sp. nov. and S. acutiapicis Y. Yang et X. Yang, sp. nov., which is differentiated from the S. laterophysus species-group by the more variable body coloration, elytra pitch black or black brown or pale-yellow, male genitalia with thick or flattened ventral processes of parameres which are diverging apically, laterophyses parallel to dorsal plates, expanded at apices, as well as the stout spermathecal duct, moderately long spermatheca and diverticulum. The above species are illustrated with photographs of habitus, male genitalia, abdominal sternites and internal genitalia of female. A key for the identification of these species is provided and a distribution map is presented.
