Revision of the genus Menevia Schaus, 1928 (Lepidoptera,Mimallonoidea, Mimallonidae) with the description of 11 new species

The Neotropical genus Menevia Schaus, 1928 is revised to include 18 species, 11 of which are new. Two species, Menevia ostia comb. n. and Menevia parostia comb. n. are transferred from Pamea Walker, 1855 to Menevia. Four species-groups are diagnosed for the first time based on external characters and male genitalia morphology. The following new species are described: Menevia rosea sp. n., Menevia torvamessoria sp. n., Menevia magna sp. n., Menevia menapia sp. n., Menevia mielkei sp. n., Menevia australis sp. n., Menevia vulgaris sp. n., Menevia franclemonti sp. n., Menevia vulgaricula sp. n., Menevia cordillera sp. n., and Menevia delphinus sp. n.. A neotype is designated for Mimallo plagiata Walker, 1855, which has since been placed in Menevia. Mimallo saturata Walker, 1855 is interpreted to be a nomen dubium.     

A new genus and nine new species of Eugnomini (Coleoptera,Curculionidae) from New Caledonia

The genus Rasilinus gen. n. is described (type species Rasilinus tchambicus sp. n.). Nine new species: Rasilinus bicolor sp. n., Rasilinus bifurcatus sp. n., Rasilinus bimaculatus sp. n., Rasilinus grandidens sp. n., Rasilinus longulus sp. n., Rasilinus subgemellus sp. n., Rasilinus subnodulus sp. n., Rasilinus tchambicus sp. n., Rasilinus virgatus sp. n. are described from New Caledonia. Illustrations of the external morphology, male and female terminalia, dorsal habitus colour photographs of the adults, key to species and distribution map of the new genus Rasilinus are provided.     

Genomic constitution and taxonomy of the Chinese hexaploids Elymus cylindricus and E. breviaristatus (Poaceae: Triticeae)

Elymus cylindricus (2n = 6x = 42) and E. breviaristatus (2n = 6x = 42) are distributed in grasslands and deserts of northern and north‐western China. Their genomic constitution and taxonomic status are unclear. Elymus cylindricus was crossed with E. wawawaiensis J.R.Carlson & Barkworth ( StH ), Roegneria grandis Keng ( StY ) and Campeiostachys dahurica (Turcz. ex Griseb.) B.R.Baum, J.L. Y ang & C. Y en var. dahurica ( StYH ). Meiotic pairing in the hybrids E. cylindricus × E. wawawaiensis ( StH ), E. cylindricus × R. grandis ( StY ) and E. cylindricus × C. dahurica var. dahurica ( StYH ) showed on average 10.00, 11.30 and 20.92 bivalents per cell, respectively. Elymus breviaristatus was crossed with C. dahurica var. dahurica ( StYH ) and E. cylindricus. Chromosome pairing in the hybrids of E. breviaristatus × C. dahurica var. dahurica and E. breviaristatus × E. cylindricus showed on average 19.60 and 19.27 bivalents, respectively. Genomic in situ hybridization (GI SH ) revealed the presence of St , Y and H genomes in E. cylindricus and E. breviaristatus. An intergenomic rearrangement was observed in E. cylindricus using GI SH . Meiotic pairing data and GI SH indicated that both E. cylindricus and E. breviaristatus are allohexaploids containing the StYH genomes. Elymus cylindricus and E. breviaristatus should be treated as Campeiostachys dahurica var. cylindrica and Campeiostachys breviaristata, respectively.     

Genome analysis ofElymus angulatus andE. patagonicus (Poaceae) and their hybrids with N. and S. AmericanHordeum spp.

The results of genome analysis of five hybrids, viz.Elymus patagonicus ×Hordeum procerum, E. patagonicus ×H. tetraploidum, E. angulatus ×H. jubatum, E. angulatus ×H. lechleri, andE. angulatus ×H. parodii, are reported. The genomic constitution ofHordeum tetraploidum andH. jubatum is best given as H₁H₁H₂H₂, ofH. lechleri andH. parodii as H₁H₁H₂H₂H₄H₄, ofH. procerum as H₁H₁H₂H₂H₃H₃, and ofElymus patagonicus andE. angulatus as SSH₁H₁H₂H₂.

Three new species of Hagnagora Druce, 1885 (Lepidoptera,Geometridae, Larentiinae) from Ecuador and Costa Rica and a concise revision of the genus

Three new Hagnagora Druce species (Geometridae, Larentiinae) are described: Hagnagora richardi Brehm, sp. n. from Ecuador, Hagnagora hedwigae Brehm, sp. n. from Ecuador, and Hagnagora mirandahenrichae Brehm, sp. n. from Costa Rica. A checklist of taxa assigned to Hagnagora is provided. Hagnagora is provisionally divided into six clades: the anicata clade (6 species), the buckleyi clade (3 species), the croceitincta clade (3 species), the ephestris clade (3 species), the mortipax clade (4 species) and Hagnagora subrosea (1 species). Two taxa are revived from synonymy: Hagnagora catagrammina Druce, stat. rev. and Hagnagora luteoradiata Thierry-Mieg, stat. rev. Two taxa are reinstated from subspecies to species level: Hagnagora acothysta Schaus, stat. rev. and Hagnagora jamaicensis Schaus, stat. rev. Four taxa are provisionally removed from Hagnagora: “Hagnagora” ignipennis, “Hagnagora” mesenata, “Hagnagora” vittata, and “Hagnagora” ceraria. After these changes, the genus Hagnagora now comprises 20 valid species.     

Revision of the Lacinipolia vicina (Grote) complex (Noctuidae,Noctuinae, Eriopygini)

The Lacinipolia vicina (Grote) species complex, previously consisting of Lacinipolia vicina, Lacinipolia teligera (Morrison), Lacinipolia pensilis (Grote), and Lacinipolia subalba Mustelin is revised to six species: Lacinipolia vicina (eastern USA), Lacinipolia teligera (southern Great Plains), Lacinipolia pensilis (Pacific Northwest and northern Rocky Mountains), Lacinipolia acutipennis (Grote), stat. rev. (= Lacinipolia subalba syn. n.) (western North America), Lacinipolia sareta (Smith), stat. rev. (Canada and western USA) and Lacinipolia dimocki, sp. n. (California and Pacific Northwest). Lectotypes are designated for Lacinipolia vicina, Lacinipolia teligera and Lacinipolia pensilis.
