New status of Bichromomyia subspecies (Diptera: Psychodidae: Phlebotominae) based on molecular taxonomy.

The sand fly of the genus Bichromomyia (Galati, 1995) includes 3 subspecies considered vectors of Leishmania, which share high morphological similarity. Through information from the Cytochrome Oxidase Subunit I (COI) gene, we provide complementary evidence to support that Bichromomyia olmeca olmeca, and Bichromomyia olmeca bicolor, should be raised to nominal species status. We recovered specimens of Bi.

Surveillance of sand flies (Psychodidae, Phlebotominae) from Mexico: Altitudinal and climatic patterns after historical and new geographic records in endemic areas of leishmaniasis.

This study updates knowledge on historical geographic distribution of sand fly species through identifying altitudinal and bioclimatic patterns in leishmaniasis endemic areas in Mexico. We analyze and identify sand fly specimens obtained through national efforts by the Instituto de Diagnóstico y Referencia Epidemiológicos (InDRE, Mexico), collected between 1995 and 2001, 2008-2012, and 2017-2023, and add bibliographic information (427 additional records). After a principal components analysis of WorldClim variables and altitudinal ranges, variables that better explain the distribution of sand fly species were chosen (BIO6, BIO12, and BIO16, explaining 72 % of variation).

Species of the thorny lacewing subfamily Symphrasinae (Neuroptera: Rhachiberothidae) are revised. Prior to this work, 42 species were known in the genera Navás, 1909, Navás, 1928, and Westwood, 1852. Herein, the number of species is increased to 60, 23 of which are newly described.

The genus Enderlein, 1910 (Neuroptera, Mantispidae) in French Guiana.

The genus Enderlein, 1910 is a remarkable group of mantidflies (Neuroptera: Mantispidae: Mantispinae) distributed from Canada to Argentina, including parts of the Caribbean. This genus comprises nine valid extant species plus an extinct species from the late Oligocene of France. Species exhibit Batesian mimicry with vespid wasps (Vespidae).

After a decade, a new Venezuelan species of Latreille (Megaloptera, Corydalidae, Corydalinae) is discovered.

A new species of dobsonfly from Venezuela, Martins, Azevêdo, Hamada & Contreras, , was discovered a decade after the last description of a species of this genus in the country. The new species is morphologically similar to Contreras-Ramos & von der Dunk, sharing a uniform reddish coloration of body and wings and similar male genitalic structures. Likewise, it shares this particular coloration with Contreras-Ramos but the genitalic structure fits within the Contreras-Ramos species group.

The present study provides descriptions of the larvae of , as well as a description of the female of .

Aquatic beetle diversity from Volcán Tacaná, Mexico: altitudinal distribution pattern and biogeographical affinity of the fauna.

Results of an aquatic beetle survey at Volcán Tacaná, Mexico, are presented with five altitudinal levels in a monthly sampling regime, aiming to estimate both diversity and altitudinal distribution patterns of the aquatic beetle fauna. The first list of aquatic beetle species from this mountain is presented, comprising 40 species in 32 genera and nine families, with four species recorded for the first time from Mexico and six recorded for the first time from Chiapas. The aquatic beetle fauna is characterized by Elmidae with 20 species, Dytiscidae with eleven species, Dryopidae with three, and Epimetopidae, Hydraenidae, Hydrophilidae, Gyrinidae, Lutrochidae, and Noteridae with one species each.

Diversity of Lacewings (Neuroptera) in an Altitudinal Gradient of the Tacaná Volcano, Southern Mexico.

Neuroptera is an order of insects with a moderate diversity of species numbers yet a high between-family morphological diversity, which has a significant ecological role as a predator. However, there are few studies focused on describing changes in species diversity along environmental gradients. We evaluated changes in the alpha and beta diversity of species and the higher taxa in Neuroptera communities in the Tacaná Volcano in southern Mexico.

Similar pattern, different paths: tracing the biogeographical history of Megaloptera (Insecta: Neuropterida) using mitochondrial phylogenomics.

The sequential breakup of the supercontinent Pangaea since the Middle Jurassic is one of the crucial factors that has driven the biogeographical patterns of terrestrial biotas. Despite decades of effort searching for concordant patterns between diversification and continental fragmentation among taxonomic groups, increasing evidence has revealed more complex and idiosyncratic scenarios resulting from a mixture of vicariance, dispersal and extinction. Aquatic insects with discreet ecological requirements, low vagility and disjunct distributions represent a valuable model for testing biogeographical hypotheses by reconstructing their distribution patterns and temporal divergences.

Comparative morphology of extant raptorial Mantispoidea (Neuroptera: Mantispidae, Rhachiberothidae) suggests a non-monophyletic Mantispidae and a single origin of the raptorial condition within the superfamily.

Adult external morphology of the extant raptorial Mantispoidea (Insecta: Neuroptera: Mantispidae and Rhachiberothidae) is compared emphasizing the morphology of the subfamily Symphrasinae as a key group to understand the phylogenetic relationships among the members of the superfamily. Plega dactylota Rehn, 1939 is thoroughly characterized in order to exemplify the morphology of the Symphrasinae. Additionally, following a review of the literature and examination of comparative material of Dilaridae, Berothidae, Rhachiberothidae and all Mantispidae subfamilies, a new interpretation of the components of the raptorial apparatus (i.

Redescription of larva of the South African endemic dobsonfly genus Chloroniella Esben-Petersen, 1924 (Megaloptera, Corydalidae), with a proposed terminology for Corydalidae larval sclerites.

Chloroniella Esben-Petersen is a relict, monotypic genus of Corydalidae (Megaloptera), considered sister to the remaining dobsonfly genera (Corydalinae); it is the only genus of Corydalinae known from the Afrotropical region. The larva of its only species, C. peryngueyi Esben-Petersen, 1924, was originally described by Barnard in 1931.

Comparative study of sensilla and other tegumentary structures of Myrmeleontidae larvae (Insecta, Neuroptera).

Antlion larvae have a complex tegumentary sensorial equipment. The sensilla and other kinds of larval tegumentary structures have been studied in 29 species of 18 genera within family Myrmeleontidae, all of them with certain degree of psammophilous lifestyle. The adaptations for such lifestyle are probably related to the evolutionary success of this lineage within Neuroptera.

A new species of Adams (Neuroptera, Chrysopidae), with a key to the species from Mexico.

The genus Adams is widely distributed in the New World, from southeastern Canada to Argentina, with 15 out of 61 previously known species recorded in Mexico. In this paper, is described and illustrated from Volcán Tacaná, Chiapas, and an identification key to species present in Mexico is provided. The new species is similar to others with swollen and darkened posterior branches of the cubital vein, and it can be separated from these other species by an elongate gonapsis extending from the base of the gonosaccus; the gonapsis is slightly upturned, terminating in a rounded apex with dorsal microteeth.

Wesmaelius (Kimminsia) nanacamilpa Marquez & Contreras, , a brown lacewing from Tlaxcala state, Mexico is described and illustrated. This is the second recorded species of from Mexico, and the third from Middle America. Males of the new species may be identified by parameres separate apically, styliform sclerites directed basally, as well as a rounded gonarcus with a short entoprocessus.

Bionomics and Ecological Services of Megaloptera Larvae (Dobsonflies, Fishflies, Alderflies).

Megaloptera belong to a large monophyletic group, the Neuropteroidea, together with Coleoptera, Strepsiptera, Raphidioptera, and Neuroptera. With the latter two, this order constitutes the Neuropterida, a smaller monophyletic subset among which it is the only entirely aquatic group, with larvae of all species requiring submersion in freshwater. Megaloptera is arguably the oldest extant clade of Holometabola with aquatic representatives, having originated during the Permian before the fragmentation of Pangea, since about 230 Ma.

Description of the pupa of Climaciella brunnea (Say) (Mantispidae, Mantispinae) and a key to known pupae of mantispids from North America.

Most works about Climaciella brunnea (Say) deal with predation and parasitoidism on wolf spiders (Lycosidae), or records of populations that mimic vespid wasps (Polistes spp.). Knowledge on immature mantispids is scarce, particularly about pupae.

Cryptochrysa Freitas Penny, a generic homonym, replaced by Titanochrysa Sosa Freitas (Neuroptera: Chrysopidae).

The green lacewing genus name Cryptochrysa Freitas Penny 2001 is identified as a junior homonym of Cryptochrysa Hampson 1926 (Lepidoptera: Noctuidae). Moreover, Titanochrysa Sosa Freitas 2012 is determined to be an available junior synonym of Cryptochrysa Freitas Penny. Thus, Titanochrysa becomes the substitute name for the preoccupied generic name.

First records of adult feeding in Megaloptera (Corydalidae, Corydalinae) from Mexico and their possible relationship with the increase in life span.

Knowledge of the natural history of the order Megaloptera is incomplete. Immatures are long-lived and widely known for their role as aquatic predators (Contreras-Ramos 1998; Azevêdo & Hamada 2007), yet information on habits of the winged terrestrial adults is limited. Previously, it was thought that adults do not feed (Table 1), perhaps because of the relatively short life span of about one week to a month (Contreras-Ramos 1998, 1999; Hayashi 1993), as well as the inability of males of Corydalus Latreille, 1802 to feed due to their large mandibles.

The nature of allometry in an exaggerated trait: The postocular flange in Platyneuromus Weele (Insecta: Megaloptera).

The origin and function of exaggerated traits exhibited by a great number of species with sexual dimorphism remain largely unexplored. The usual model considered as the evolutionary mechanism for the development of these structures is sexual selection. The nature of growth of the postocular flange (POF) in three species of the dobsonfly genus Platyneuromus (Megaloptera, Corydalidae, Corydalinae) is analyzed to explore sexual size dimorphism and allometric scaling.

The phylogeny of brown lacewings (Neuroptera: Hemerobiidae) reveals multiple reductions in wing venation.

Background: The last time the phylogenetic relationships among members of the family Hemerobiidae were studied quantitatively was over 12 years ago and based exclusively on morphology. Our study builds upon this morphological evidence by adding sequence data from three gene loci to provide a total evidence phylogeny of brown lacewings (Neuroptera: Hemerobiidae). Thirty-seven species representing nineteen Hemerobiidae genera were compared with outgroups from the families Ithonidae, Psychopsidae and Chrysopidae in Bayesian and parsimony analyses using a single nuclear gene (CAD) and two mitochondrial (16S rDNA and Cytochrome Oxidase I) genes.
