Jumping bristletail (Insecta: Apterygota: Microcoryphia) records in the southeastern United States
(2020)
Few records of Microcoryphia exist for the southeastern United States, with named species being reported only from Arkansas, Tennessee, and the mid-Atlantic states, and with an unnamed species being reported from Georgia. Records are here provided from 291 specimens housed in the Mississippi Entomological Museum, including ten new species-level state records. This is also the first published report of the order Microcoryphia from Alabama and Mississippi. Species include the machilids Pedetontoides atlanticus Mendes in Alabama, Arkansas, Georgia, Mississippi, and North Carolina; Pedetontus cf. atlanticus in Kentucky; Pedetontus (Verhoeffilis) gershneri Allen in Arkansas; and Pedetontus (Pedetontus) saltator Wygodzinsky and Schmidt in Mississippi and North Carolina; and the meinertellid Machiloides banksi (Silvestri) in Alabama, Arkansas, Mississippi, and North Carolina.
Ancognatha aymara Mondaca, 2016 (Coleoptera: Scarabaeidae: Dynastinae: Cyclocephalini), a species previously known only from Chile, is recorded for the first time in northern Argentina. The new records are based on male specimens collected in the provinces of Jujuy and Salta. Illustrations of the habitus and male genitalia of the species are presented in color photographs. A map with its current distribution in Chile and Argentina is included.
Matsucoccus krystalae Ahmed and Miller, new species, (Hemiptera:Coccomorpha: Matsucoccidae) is described based on morphological characters of adult females and third-instar males. We designate the lectotype of Matsucoccus alabamae Morrison. Matsucoccus alabamae Morrison and M. gallicolus Morrison are redescribed, also based on adult females and third-instar males. Detailed illustrations and descriptions are presented for each species and an identification key for the five species occurring in the eastern U.S. is provided. Analysis of 18S, 28S D2/D3, and 28S D10 loci were performed to support morphological determination. Barcodes using 5′ COI of M. alabamae and M. krystalae were generated, the first such data from authoritatively identified Matsucoccus species. Of particular interest is that most of the specimens in the study were taken in Lindgren funnel traps.
The present checklist covers the fauna of the Trichopteran family Rhyacophilidae Stephens, 1836. Based on extensive surveys done during 2003–2019 and previous species records, we find that the family Rhyacophilidae is represented by two genera and 184 species in India. The genus Rhyacophila Pictet contains 165 species in India while the genus Himalopsyche Banks contains 19 described species. The Indian Himalayan region is inhabited by more species than the rest of India.
Psyllids are an economically important group of insects. Several species are serious emerging pests with regulatory significance. About 20 adventive species have been discovered in Florida in the past 20 years, including several pests. Additionally, five species new to science have been found. We provide an annotated checklist of Florida species with taxonomic information and identification tools, including keys to Florida genera and known species. Seventy species of Psylloidea currently are reported from Florida. Forty-one are native to Florida, with 12 endemic to the state. Twenty are adventive, the majority being from the Neotropics. One was introduced deliberately for biological control, seven represent temporary populations (eradicated, reared in quarantine), and one is a dubious record. Craspedolepta euthamiae Burckhardt and Halbert, new species, Katacephala wineriterae Burckhardt and Halbert, new species, Pseudophacopteron gumbolimbo Burckhardt and Halbert, new species, Nothotrioza longipedis Burckhardt and Halbert, new species, and Trioza myresae Burckhardt and Halbert, new species are described from Florida and are native endemic species. Aphalara persicaria Caldwell is redescribed and separated from similar species. Aphalara persicaria var. cubana Caldwell is confirmed as a junior synonym of Aphalara persicaria. The Florida records of Craspedolepta spp. are revisited and revised, including Craspedolepta euthamiae Burckhardt and Halbert, new species. Bactericera nigrilla (Crawford), new combination, revived status is recognized from Florida, redescribed, and distinguished from similar species. Rhinopsylla caldwelli Tuthill is transferred to Kuwayama Crawford and becomes Kuwayama caldwelli (Tuthill), new combination.Trioza maritima Tuthill is transferred to Leuronota Crawford and becomes Leuronota maritima (Tuthill), new combination. Species of Bactericera Puton on Salix L. (Salicaceae) in North America are reviewed. Bactericera flori (Crawford), new combination, new status. is determined to be the correct name for Trioza assimilis Crawford nec Flor (= Trioza flori Crawford, replacement name, = Trioza pomonae Aulmann, replacement name), and Trioza dubia Patch, new synonym. Lectotypes are designated for Trioza marginata Crawford, Trioza minuta Crawford, Trioza minuta similis Crawford, and Trioza nigra Crawford.
The genus Parasogata Zhou, Yang & Chen, 2018 is here reported from India represented by the new species Parasogata sexpartita sp. nov. collected in a recent exploration and survey of delphacids from Nagaland in northeastern India. A second species of Eoeurysa Muir, 1913 from India, the new species Eoeurysa sagittaria sp. nov., was found in Rampur, Una, Himachal Pradesh. Both new species are described with illustrations, and a molecular identification is given with the mtCOI gene sequence. A modified key to species of the genera is also provided.
All extant species of the planthopper genus Limois Stål (Hemiptera: Fulgoromorpha: Fulgoridae) were studied. One new species, Limois sordida sp. nov., is described and illustrated from China. Six known species are re-described and photos and illustrations of male genitalia are provided. A key to all extant species of this genus is also given.
Species are often presumed to be apparent in nature, but in practice they may be difficult to recognise, especially when viewed across continents rather than within a single site. Coalescent-based Poisson-tree-process (PTP) models applied to fast-evolving genes promise one quantitative criterion for recognising species, complete with the estimates of uncertainty that are required of a scientific method. Such methods face challenges especially in discerning between widespread polytypic species and complexes of closely related, restricted-range species. In particular, ‘over-sampling’ of many closely related individuals within one species could risk causing groups of less closely-related individuals within other species appearing relatively more distinct and consequently could risk them being interpreted falsely as separate species. Some of the most persistent taxonomic problems among bumblebees (genus Bombus Latreille, 1802) are within the subgenus Melanobombus von Dalla Torre, 1880. For a global revision of Melanobombus species, we use COI barcodes and seek to reduce the risk from localised over-sampling by filtering the data to include only unique haplotypes. Unique haplotypes give more conservative results than unfiltered data, but still increase the number of species in comparison with recent morphological treatments. After integrative assessment of COI coalescents in comparison with morphological groups, the number of accepted species shows a non-linear increase with sample size that plateaus to an increase of 47% (to 25 species) compared with a previous estimate (of 17) based on morphology alone. For the most widespread and variable species-complexes, our revised species improve the match to the patterns expected of species, both for genetic divergence-with-distance and for sympatry, leading to three main inferences. (1) The particularly widespread polytypic Bombus sichelii Radoszkowski, 1859, is a single species. (2) We detect two candidates for species within previous broad concepts of each of the former B. lapidarius (Linnaeus, 1758), B. miniatus Bingham, 1897, and B. rufofasciatus Smith, 1852. Within B. lapidarius s. lat. we find insufficient evidence to corroborate the candidate species, with no coalescent or morphological support for a recent claim for a separate species, B. bisiculus Lecocq, Biella, Martinet & Rasmont, 2019 described from southern Italy, but rather we find a weak and uncorroborated coalescent for a different and much broader group of samples from across southeastern Europe but excluding Turkey. Within the former broad concepts of B. miniatus s. lat. and B. rufofasciatus s. lat. the coalescent evidence is stronger and subtle evidence from morphology corroborates recognising B. miniatus s. str. and B. eurythorax Wang, 1892 stat. rev. as separate species as well as B. rufofasciatus s. str. and B. prshewalskyi Morawitz, 1880 stat. rev. as separate species. (3) Our coalescent and morphological results ‘split’ more clearly what has long been interpreted as a single polytypic B. keriensis Morawitz, 1887, s. lat., by supporting novel concepts of the restricted-range species: B. alagesianus Reinig, 1930 stat. rev., B. incertoides Vogt, 1911 stat. rev., B. keriensis s. str., B. qilianensis sp. nov., B. separandus Vogt, 1909 stat. rev., and B. tibeticus sp. nov. A lectotype is designated for the name B. keriensis and a neotype is designated for the name B. alagesianus. We estimate the phylogeny of Melanobombus species by including three slower-evolving genes to provide more evidence for deeper relationships, to estimate the time calibration of this phylogeny, and to estimate ancestral distributions, all within a Bayesian framework. We provide the first keys for identifying all of the species of Melanobombus.
Based on samples collected during the BIOICE project off Iceland, four species of marine annelids belonging to the family Pectinariidae were identified: Amphictene auricoma (O.F. Müller, 1776), Cistenides granulata (Linnaeus, 1767), Cistenides hyperborea Malmgren, 1865 and Lagis koreni Malmgren, 1866. Taxonomic remarks and data on geographical and bathymetric distribution are presented. The distribution of each species off Iceland was evaluated and two patterns were defined: C. granulata and C. hyperborea were mainly found in waters off the northeast coast, while A. auricoma and L. koreni were found on the southern coast. Several body characters with taxonomic value in this family were reviewed under the stereo microscope and scanning electron microscope, with special emphasis on the neuropodial uncini. Remarks on these special chaetae are included in the diagnoses.
The spider genus Bistriopelma Kaderka, 2015 is endemic to Peru and includes three species known to date: Bistriopelma lamasi Kaderka, 2015, B. matuskai Kaderka, 2015 and B. titicaca Kaderka, 2017. The present contribution diagnoses, describes and illustrates two new species of Bistriopelma from Peru: B. peyoi sp. nov. and B. kiwicha sp. nov., both based on male and female. The male of B. peyoi sp. nov. is provided with a remarkable thoracic horn, and the species is the first horned tarantula for this genus. An updated distribution map for all known species is presented.
