Specimens of a bark beetle, Crypturgus hispidulus Thomson, 1870, were discovered in New England, U.S.A. This is the first record of this species established in North America. Misidentified specimen ...records were found from multiple states in different years, confirming establishment of the species in the Northeastern United States. The morphology is presented and a modified key to Crypturgus in North America is provided to facilitate species identification.
Diagnostic characters for all 11 valid genera of Euchromadorinae are presented with taxonomic key on the basis of morphology of male copulatory apparatus, cuticular pattern, amphideal fovea, and ...buccal onchia. The key to the species of Trochamus spp. is also constructed with the description of T. timmi sp. n. from the mud-flat of Sundarban, India. The newly described species is different from other Trochamus spp. on the basis of the appearance of lateral differentiation of cuticle, long curved spicule, simple gubernaculum and the presence of pre-cloacal modification in male.
Estudos com chave de identificação dendrológica e o comportamento fenológico aliado ao conhecimento das espécies ameaçadas de extinção da flora arbustivo-arbórea do Cerrado no Estado do Tocantins ...ainda são escassos ou incipientes, promovendo assim uma lacuna de informações técnicas e científicas. Portanto, esta pesquisa visa respaldar o estabelecimento de prioridades para futuras estratégias de conservação e planos de manejo de espécies botânicas do Cerrado. Diante do contexto, objetivou-se elaborar uma chave dicotômica, baseada em caracteres vegetativos das espécies arbustivo-arbórea de uma área de cerrado sensu stricto em Gurupi – TO. Foram alocadas, sistematicamente, cinco parcelas permanentes de 20×50m, ou seja, 1000 m² cada, sendo as mesmas distanciadas 10 m entre si. Amostrou-se todos os indivíduos arbustivo-arbóreos, com circunferência a 1,30 m do solo (CAP) maior ou igual a 10 cm. Os materiais botânicos das espécies foram herborizados seguindo as técnicas convencionais. Para a elaboração da chave de identificação, foi realizada uma seleção dentre as 106 espécies amostradas, considerando apenas as espécies que possuíam densidade absoluta maior ou igual a 5 indivíduos, desta forma foram selecionadas 54 espécies. Cabe ressaltar que essa seleção teve como objetivo incluir apenas as espécies de maior recorrência no cerrado sensu stricto, com finalidade de viabilizar a funcionalidade da chave. A chave de identificação baseada em caracteres vegetativos foi composta por 54 espécies arbustivo-arbóreas de eudicotiledôneas e angiospermas basais, distribuídas em 47 gêneros, incluídos em 26 famílias botânicas. A confecção da chave de identificação dendrológica demonstrou-se uma ferramenta funcional, ou seja, permitiu uma rápida e fácil identificação das espécies vegetais amostradas.
The Polycentropus confusus Species Group (Trichoptera: Polycentropodidae) comprises 19 nominal species occurring throughout the eastern Nearctic Region. This group has never been comprehensively ...treated, prompting its full revision here. Males of all 19 species are redescribed and illustrated, and the 14 known females of the group are described and illustrated, including the original descriptions and illustrations for the females of P. alabamensis Hamilton, Harris, and Lago, 1990, P. carolinensis Banks, 1905, and P. chelatus Ross and Yamamoto, 1965. Neotypes are designated for P. alabamensis and P. elarus Ross, 1944, and dichotomous keys to males and females are provided. New state and province records are reported, one new country record is reported, erroneous records are corrected, biological notes are provided, and the known distribution of each species is summarised.
The present study provides the morphotaxonomic-based identification of the world species of the subgenus Oligonychus (Oligonychus) Berlese. In this lieu, five diagnostic keys were erected to identify ...Oligonychus (O.) species belonging to five subgroups; smithi, peruvianus, subnudus, aceris, and coffeae. In addition, taxonomic notes on some Oligonychus (O.) species, either briefly described or closely related, were provided, and intraspecific variations were highlighted.
Both macrofossil and microfossil plant remains from the grass family (Poaceae) have been recovered from Neolithic and historic sites in China. Basing our work on the plant taxa that were previously ...recovered, we analyzed the economically significant genera for modern starch grain analysis with a focus on the important tribe Triticeae. Modern starch grains from the tribe Triticeae were compared with those from other grasses, and criteria for identification were determined. In total, 38 species within 28 genera, 13 tribes and 4 subfamilies were selected for analysis. Results demonstrate that starch grains from members of the tribe Triticeae are discernible from those of other tribes by their distinctive lenticular morphologies and surficial pressure craters. A dichotomous key covering 10 species within 7 genera of the Triticeae was created, thus allowing identification of members of the tribe to the level of genus. Application of the dichotomous key to the ancient starch assemblage recovered from lithic tools excavated from the early Neolithic site of Donghulin demonstrates that plants from the genera Hordeum and Agropyron were exploited alongside millets at this site.
•Morphological starch data are presented from 38 species in the family Poaceae.•A dichotomous key to identify wheat-related grasses in East Asia is presented.•Plants from the genus Hordeum were exploited 10,000 years ago in North China.
The Indian subcontinent is known to harbor a high level of insect biodiversity and endemism, but the grasshopper fauna in this region is poorly understood, in part due to the lack of appropriate ...taxonomic resources. Based on detailed examinations of museum specimens and high-resolution digital images, we have produced an illustrated key to 21 Pyrgomorphidae genera known from the Indian subcontinent. This new identification key will become a useful tool for increasing our knowledge on the taxonomy of grasshoppers in this important biogeographic region.
Krishnacapritermes Chhotani (Isoptera: Termitidae) is one of the endemic termite genera from the Western Ghats of India. Under the genus, only two species Krishnacapritermes maitii Chhotani and ...Krishnacapritermes thakuri Chhotani were known earlier. The present study describes two new species, Krishnacapritermes dineshan Amina and Rajmohana sp. nov. and Krishnacapritermes manikandan Amina and Rajmohana sp. nov. from the higher elevation hill ranges of Western Ghats part of Kerala. DNA barcodes based on cytochrome oxidase I genes were generated for K. thakuri and K. dineshan from multiple locations and tested for phylogenetic relationships. The paper provides a dichotomous key for the four species of Krishnacapritermes and a species distribution map, along with data on the extension of distribution range for K. maitii and K. thakuri. Comments on intracolonial variability of the hyaline lateral points or processes of the labrum in soldier caste are included. Pericapritermes travancorensis Mathew and Ipe syn. nov. is treated as a junior synonym of K. thakuri.

The enigmatic ‘y-larvae’ (Thecostraca: Facetotecta) are microscopic marine planktonic crustaceans that were discovered more than a century ago, yet to this day their adults remain unknown. Despite ...occurring locally in large diversities, and therefore presumably being of ecological importance, only 17 species have been described globally, rendering it practically impossible to identify any y-larval specimen from any locality. The fact that species have been based on different life stages (nauplii and/or cyprids) further hampers identification. Y-larvae include many forms with planktotrophic (feeding) nauplii and even more with lecithotrophic (non-feeding) nauplii. At one coral-reef locality on the shore of Sesoko Island (Okinawa, Japan), extensive fieldwork in 2018 and 2019 confirmed an enormous taxonomic diversity of y-larvae there. Here, we present morphological diagnoses and an identification key for 34 lecithotrophic y-naupliar types (or morphospecies), which will correspond minimally to the same number of species when described. As a temporary measure, all are referred to by alphabetical parataxonomic designations, except for three that have been formally described already within the genus Hansenocaris Itô, 1985. To this should be added an additional 7–9 planktotrophic y-naupliar morphospecies, which are only treated briefly. Most often, y-larval taxonomy has been based on the cyprid stage, but the large morphological diversity of y-nauplii suggests that nauplii are at least as important for taxonomy. Lecithotrophic y-nauplii display a multitude of body shapes, the form-evolution of which is discussed here with reference to a recent molecular phylogeny of Facetotecta partly based on material from the same site. An indirect estimate of the relative abundances of all 34 lecithotrophic y-naupliar morphospecies is presented, based on laboratory-reared final-instar specimens. This treatment is intended as a step towards a proper taxonomy and a revised classification of Facetotecta, which will involve detailed descriptions of both nauplii and cyprids. Until such work progresses, the present overview of the y-naupliar fauna of a single Okinawan locality known to be a hotspot of y-larval diversity is offered as a baseline for further surveys of Facetotecta elsewhere in the Indo-West Pacific and beyond.
