Osmylidae is a small family of Neuroptera with a worldwide distribution. Only four subfamilies and five genera of Osmylidae have been reported to date for the Neotropical region, with a total of 16 species, whilst 200 species are known in the world. In this study three new species are described-Isostenosmylus bifurcatus n. sp., I. irroratus n. sp. and I. julianae n. sp. Moreover, species of Gumilla Navás, 1912 and Paryphosmylus Krüger, 1913 are redescribed; additionally one larva of Isostenosmylus sp. and the female of Isostenosmylus fasciatus Kimmins, 1940 are described. Images of type specimens of Neotropical species of Osmylidae are provided. New records of known species are reported and a distribution map is presented. An updated checklist and a key for Neotropical species of Osmylidae are provided.
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.e., head, prothorax, grasping forelegs, as well as integumentary specializations) is presented. Also, wing venation for these groups is reinterpreted, and new homology hypotheses for wing venation are proposed based on tracheation and comparative analyses. Given the high morphological divergence on the genital sclerites within the Mantispoidea, plus the confusing previous usage of neutral terminology and terms referring to appendages across taxonomic and morphological studies, we attempt to standardize, simplify, and situate terminology in an evolutionary context under the “gonocoxite concept” (multi-coxopod hypothesis). The remarkable morphological similarity of the genital sclerites of Symphrasinae and Rhachiberothidae (sensu U. Aspöck & Mansell 1994) with the Nallachinae (Dilaridae) was taken as a starting point to understand the morphology of other Mantispidae subfamilies. Based on these morphological comparisons, we provide a revised phylogenetic analysis of Mantispoidea. This new phylogenetic analysis supports a sister group relationship between the family Rhachiberothidae, comprising Rhachiberothinae and Symphrasinae, and the family Mantispidae, including the subfamily Mantispinae and its sister taxa Drepanicinae and Calomantispinae, which may represent a single subfamily. Based on these analyses, raptorial condition probably evolved a single time in these insects and subsequently became diversified in the two sister clades of the raptorial Mantispoidea.
Approximately 340 species of ten families of Neuroptera have been recorded from Mexico. The Tacaná volcano, reaching an elevation of 4092 m a.s.l., is the northernmost representative of the Central American Nucleus volcanic range. Recent survey efforts of the Neuroptera diversity of the Tacaná volcano, Chiapas, along an altitudinal gradient, increased the known fauna of this order in Mexico by 31 species and two genera: Biramus Oswald, 1993 (Hemerobiidae), and Titanochrysa Sosa & Freitas, 2012 (Chrysopidae), with extension of the known distributional range of 25 species of five families. Most of the new country records are from species previously known only from Central and South America. The lacewing fauna of Chiapas is updated from 91 to 147 species. The Neuroptera of the Tacaná volcano is mostly Neotropical with some taxa of Nearctic affinity restricted to medium and high elevations. More than 80% of the Tacaná volcano lacewing species also occur in the Brazilian subregion, especially the Mesoamerican and Pacific domains. Neuropteran species were recorded from 650 to more than 3500 m a.s.l. A higher species richness was present between 600 and 1700 m, with a few species occurring at altitudes above 3000 m. A species checklist and an identification key to the genera of Neuroptera of the Tacaná volcano are provided.
The genera of the lance lacewing family Osmylidae (Neuroptera) and extinct allied families (Archeosmylidae, Saucrosmylidae) are reviewed. A key to living Osmylidae genera of the world is presented. Each genus is diagnosed and figured with a checklist of species included for each. New, revised or support for previous taxonomic changes include the following: Nuddsia Menon & Makarkin, 2008 (= Burmaleon Myskowiak et al., 2016 syn. nov.); Kempynus Navás, 1912 (= Clydosmylus New 1983a syn. nov.); Osmylus Latreille, 1802 (= Hyposmylus McLachlan; Dictyosmylus Navás, 1910; Plesiosmylus, Makarkin, 1985; Plethosmylus Krüger, 1913a); Parosmylus Needham, 1909 (= Mesosmylus Krüger, 1913c; Phlebosmylus Navás, 1928 syn. nov.); Thaumatosmylus Krüger, 1913a (= Glenosmylus Krüger, 1913a syn. nov.). New classification changes include: Mesomylidus Jepson, 2012 and Petrushevkia Martynova, 1958 are transferred to Protosmylinae; Lahulus Navás, 1930 is placed in Osmylinae; Stenosmylina Jepson et al., 2009 is transferred to Eidoporisminae. Cratovoluptia Martins-Neto & Rodrigues, 2009 is removed from Osmylidae and transferred to Ithonidae, while Cratosmylus Myskowiak et al., 2015 is transferred to Nymphidae. Idiastogyia Lin, 1986 and Yanosmylus Ren in Ren et al., 1995 are excluded from Osmylidae and placed as incertae sedis in Neuroptera.
A global synonymical checklist of the species and higher taxa of the insect order Megaloptera is provided. The checklist includes both extant and extinct taxa, and recognizes 2 families, 4 subfamilies, 48 genera, 425 species, and 6 subspecies. Both families (Corydalidae and Sialidae), and three of the four subfamilies (Corydalinae, Chauliodinae, and Sialinae) are known from both extant and extinct species; the Sharasialinae (Sialidae) is entirely extinct. Country-level geographic distribution data are provided for all species and subspecies. Synoptic type data are provided for taxa in the family and genus groups. Summary data are given for the numbers of megalopteran species currently known to occur in each of the major biogeographical regions of the world, and for the world fauna. Increase of knowledge about the diversity of the world Megaloptera fauna is summarized in counts of valid species described per decade and in a global taxonomic description curve. An updated set of keys to the world families, subfamilies, and genera of the Megaloptera is also provided.
In recent years many studies have been undertaken on the species of the genus Dilar Rambur, 1838 that occur in Asia, these have greatly increased the knowledge of Dilaridae in that region. Dilar has 69 valid species distributed in the Palaearctic and Oriental regions. In this paper we describe a new species Dilar aspoeckorum sp. nov. from Vietnam and a new female (probably Dilar harmandi (Navás, 1909)) from Nepal.
Two subfamilies and three genera of Coniopterygidae have been reported to date for Brazil, with a total of 44 of species. In this paper two new Brazilian species are described from the genera Coniopteryx Curtis, 1834 and Incasemidalis Meinander, 1972-C. (Scotoconiopteryx) letardii sp. n. and Incasemidalis brasiliensis sp. n. -increasing the number of reported genera for Brazil to four and the number of Brazilian species to 46. This is the first report of Incasemidalis for Brazil. Moreover, in the case of C. (C.) callangana Enderlein, 1906, C. (Scotoconiopteryx) flinti Meinander, 1975, C. (S.) tucumana Navás, 1930, Semidalis nimboiformis Monserrat, 1989 and S. normani Meinander, 1982 some additional characteristics are given to the original descriptions or earlier redescriptions, with new records increasing their known distribution. An updated checklist of the Coniopterygidae from Brazil is provided, as well as a key for the Brazilian species of the family.
Coffea canephora (Conilon coffee) has great economic importance for the state of Acre, in northern Brazil. The use of insecticides in this crop has increased considerably in recent years. In order to find species of green lacewing (Chrysopidae, Neuroptera) with potential for use in biological pest control in coffee plantations, we sampled green lacewings during one year in an experimental plantation of Conilon coffee in Acre, in order to assess the diversity, abundance and seasonal occurrence of Chrysopidae species. Samplings were carried out weekly using an entomological net. Overall, 1079 specimens of seven green lacewing species were collected: Ceraeochrysa cincta, Ceraeochrysa claveri, Ceraeochrysa cubana, Ceraeochrysa everes, Chrysoperla externa, Leucochrysa (Nodita) cruentata and Leucochrysa (Nodita) marquezi. Ceraeochrysa cubana was the dominant and constant species, comprising 97% of the sampled specimens and occurring in 82% of the weekly samples. The abundance and constant presence of C. cubana, which preys upon several agricultural pests and has shown resistance to various insecticides, make this species a potential candidate for future programs of biological control in Conilon coffee plantations in the southwestern Brazilian Amazon region.
