Description of the females of two species of the genus Lasaia (Lepidoptera: Riodinidae) and new records for Mexico.

Females of two species of the genus Lasaia Bates, 1868, L. arsis Staudinger, [1887] and L. pseudomeris Clench, 1972 are described from specimens deposited in entomological collections.

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.

Geographical distribution of Emesis/ Fabricius (Lepidoptera: Riodinidae) in Mexico: Updated checklist and temporal patterns.

We present a synthesis of the existing information on the genus Emesis Fabricius in Mexico concerning biogeographical patterns and taxonomical aspects. Emesis is the most diverse genus of Emesidini with 57 species and subspecies, with Mexico as the northern limit of this Neotropical genus. We analyzed 5434 specimens of the Lepidoptera Collection of the MZFC, UNAM and compared them with specimens from collections of Mexico, Central and South America.

Challenges for organismic taxonomical revisions in the age of phylogenomics: A response to Zhang et al. (2019).

Tribe Emesidini Seraphim, Freitas Kaminski (Lepidoptera: Riodinidae) is distributed in America from southwest Canada to Brazil and Paraguay, and includes 57 species and 54 subspecies (Callaghan Lamas 2004; Penz DeVries 2006; Gallard 2008; Pelham 2008; De la Maza De la Maza 2017 a,b; Kaminski et al. 2017; Seraphim et al. 2018; Trujano-Ortega et al.

Emesis planeca n. comb. (Lepidoptera: Riodinidae): a new combination revealed by molecular evidence with a description of its morphological variation.

We transfer Apodemia planeca R. de la Maza E. J.

Geographical distribution of Lasaia Bates, 1868 (Lepidoptera: Riodinidae) across the biogeographical provinces of Mexico.

Riodinidae are one of the most diverse families of Lepidoptera, mainly in the Neotropical region; however, their biology, ethology, taxonomy, systematics, and biogeography are poorly known. In Mexico, the regional and local distributions of the family are still incomplete. We review the distributional data of the genus Lasaia Bates (Lepidoptera: Riodinidae), based on records from four national and seven international collections.

Use of exochorion characters for the systematics of Hamadryas Hübner and Ectima Doubleday (Nymphalidae: Biblidinae: Ageroniini).

We studied the chorionic morphology of six species of Hamadryas, and together with previous studies, we compared our results with previously published phylogenies for the genus. Samples were obtained from 19 females collected between 2013 and 2017 whose abdomens were sectioned and preserved for later dissection. Eggs were extracted from those dissections and used for the descriptions and illustrations of the chorion.

A new species of Cyllopsis R. Felder, 1869 from the highlands of Chiapas, Mexico (Lepidoptera: Nymphalidae: Satyrinae).

A new species of Cyllopsis R. Felder, 1869, is described and illustrated from the highlands of Chiapas, Mexico. Cyllopsis tomemmeli A.

Papilionoidea (Insecta: Lepidoptera) type specimens at the Museo de Zoología "Alfonso L. Herrera" from Universidad Nacional Autónoma de México.

We list and illustrate Papilionoidea (s. l.) type specimens deposited in the Museo de Zoología "Alfonso L.

[A new subspecies of Heraclides androgeus (Lepidoptera: Papilionidae) and its biogeographical aspects].

A new subspecies of Heraclides androgeus (Lepidoptera: Papilionidae) and its biogeographical aspects. Heraclides androgeus epidaurus was described and illustrated by Godman & Salvin in 1890 based on specimens obtained in Veracruz, indicating that their distribution encompassed both the Pacific and Atlantic sides of Mexico. Later authors commented that there were morphological differences between the male wings from both populations.

A new species of Euselasia Hübner from Meso-America and Mexico with notes on the eurypus group (Lepidoptera, Riodinidae).

A new species of Riodinidae, Euselasia oaxacensis Callaghan, Llorente-Bousquets & Luis-Martinez, sp. nov. from Oaxaca State in Mexico and Costa Rica is described, including its habitat, behavior and differences with other members of the eurypus group of the genus Euselasia.

[Distribution of butterflies (Lepidoptera: Hesperioidea and Papilionoidea) from Mexico State, Mexico].

The State of Mexico is a region with great biological diversity, owing to its geographical and ecological features. Regarding Hesperioidea and Papilionoidea, 15% of the Mexican species are recorded in the State of Mexico, 17% of which are endemic to the country. A checklist of the two superfamilies for the State of Mexico was integrated, based on published literature and databases at the Museo de Zoología of the Facultad de Ciencias, UNAM.
