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.
Two new species of the millipede genus Anamastigona are described, A. cypria sp. nov. and A. strasseri sp. nov., both from the island of Cyprus. The new species are considered to be most similar to A. terraesanctae Golovatch & Makarov, 2011 from Israel, the three of them forming a species group which is briefly characterized. An updated key to all 20 recognized species of the genus Anamastigona is provided and a short overview of the taxonomy of the genus is given.
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.
Three families in the superfamily Calopterygoidea occur in China, viz. the Calopterygidae, Chlorocyphidae and Euphaeidae. They include numerous species that are distributed widely across South China, mainly in streams and upland running waters at moderate altitudes. To date, our knowledge of Chinese species has remained inadequate: the taxonomy of some genera is unresolved and no attempt has been made to map the distribution of the various species and genera. This project is therefore aimed at providing taxonomic (including on larval morphology), biological, and distributional information on the superfamily in South China.
The Antillean fauna of Mantispidae (Neuroptera) consists of six species in four genera, all in the subfamily Mantispinae. Two new species are here described: Leptomantispa antillesensis Hoffman, n. sp., is described from Puerto Rico, Anguilla, British Virgin Islands (Grand Camanoe, Guana, Tortola), United States Virgin Islands (St. Croix, St. John, St. Thomas), Dominica, and Guadeloupe, and Leptomantispa hispaniolaensis Hoffman, n. sp. is described from Hispaniola (Dominican Republic). Mantispilla zayasi Alayo is synonymized under Leptomantispa pulchella (Banks), new synonomy, and Mantispilla taina Alayo is synonymized under Zeugomantispa minuta (Fabricius), new synonomy. Climaciella cubana Enderlein is recorded for the fi rst time from Hispaniola (Dominican Republic). Dicromantispa sayi (Banks) is newly reported from the Cayman Islands (Cayman Brac and Little Cayman), and Hispaniola (Dominican Republic). Zeugomantispa minuta (Fabricius) is now recorded from the Bahamas (Andros) and Hispaniola (Dominican Republic).
The genus Brachypsectra LeConte, 1874 (Coleoptera: Brachypsectridae) in the Palaearctic Region
(2017)
We summarize all information regarding the genus Brachypsectra (Coleoptera: Brachypsectridae) in the Palaearctic Region. New material of B. kadleci Hájek, 2010 is reported from western and southern Iran and its intraspecific variability in coloration and morphology is described and figured. Brachypsectra jaechi sp. nov. from southern Turkey is described from males, and an unassociated Brachypsectra species from Cyprus is reported, including the descriptions of its female and larva. These findings are the first records of this genus as well as of the family Brachypsectridae for Turkey and Cyprus. Additionally, a diagnostic key to the adult males and larvae of all Brachypsectra species is updated.
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 genus Bembidion Latreille (Carabidae: Bembidiini) is reviewed for New Zealand. Thirty-six species-group taxa are recognized. Seven species are described as new: Bembidion (Zecillenus) karikari new species, Bembidion (Zecillenus) puponga new species, Bembidion (Zecillenus) tepaki new species, Bembidion (Zecillenus) waimarama new species, Bembidion (Zemetallina) bullerense new species, Bembidion (Zemetallina) mangamuka new species, Bembidion (Zemetallina) waiho new species. The taxonomic status of two species-group taxa is changed (valid names listed after equal sign): Bembidion (Zeactedium) orbiferum giachinoi Toledano, 2005 = Bembidion (Zeactedium) giachinoi Toledano, 2005; Bembidion (Zeperyphodes) nesophilum Broun, 1886 (previously synonymized with Bembidion (Zeperyphodes) callipeplum Bates, 1878) is resurrected from synonymy. A new synonymy is established (valid name listed after equal sign): Bembidion (Ananotaphus) rotundicolle eustictum Bates, 1878 = Bembidion (Ananotaphus) rotundicolle Bates, 1874. A concise review of the taxonomy of all taxa is provided.
