Worker Caste

The formicine ant genus Prenolepis is here revised for the first time. Thirteen extant species are recognized of which four are described as new. A key for the worker caste is provided, and the worker of each species is imaged, with males and queens imaged in species where they are known. Worker-based characters were used to construct a species-level phylogeny of Prenolepis. Both maximum parsimony and Bayesian inference methods were used for the phylogenetic analyses. A morphological diagnosis for the genus is provided, with a discussion of useful morphological characters for separating Prenolepis from other genera in the Prenolepis genus-group. Major taxonomic changes are proposed. The new species are: P. darlena, P. fustinoda, P. mediops, and P. shanialena. Prenolepis jerdoni subopaca is elevated to full species. Three species are excluded from Prenolepis and transferred to Nylanderia and Paratrechina as new combinations: N. emmae, N. flaviabdominis, and P. umbra. Two species are excluded from Paratrechina and transferred to Nylanderia and Paraparatrechina as new combinations: N. guanyin and P. kongming. One species, Z. darlingtoni, is excluded from Nylanderia and transferred to Zatania as a new combination. Several synonyms are proposed: Prenolepis sphingthoraxa = Nylanderia flaviabdominis; P. imparis arizonica, P. imparis colimana, P. imparis coloradensis, and P. imparis veracruzensis = P. imparis; P. melanogaster carinifrons and P. nigriflagella = P. melanogaster; P. longiventris and P. magnocula = P. naoroji; and P. septemdenta = Nylanderia opisopthalmia.

AbstractThe eastern Mediterranean basin hosts a remarkably high plant diversity. Historical connections between currently isolated areas across the Aegean region and long-distance dispersal events have been invoked to explain current distribution patterns of species. According to most recent treatments, at least two Cymbalaria species occur in this area, Cymbalaria microcalyx and C. longipes. The former comprises several intraspecific taxa, treated at different ranks by different authors based on morphological data, evidencing the need of a taxonomic revision. Additionally, some populations of C. microcalyx show exclusive morphological characters that do not match any described taxon. Here, we aim to shed light on the systematics of eastern Mediterranean Cymbalaria and to propose a classification informed by various sources of evidence. We performed molecular phylogenetic analyses using ITS, 3’ETS, ndhF and rpl32-trnL sequences and estimated the ploidy level of some taxa performing relative genome size measures. Molecular data combined with morphology support the division of traditionally delimited C. microcalyx into C. acutiloba, C. microcalyx and C. minor, corresponding to well-delimited nrDNA lineages. Furthermore, we propose to combine C. microcalyx subsp. paradoxa at the species level. A group of specimens previously thought to belong to Cymbalaria microcalyx constitute a well-defined phylogenetic and morphological entity and are described here as a new species, Cymbalaria spetae. Cymbalaria longipes is non-monophyletic, but characterized by being glabrous and diploid, unlike other eastern species. The nrDNA data suggest at least two dispersals from the mainland to the Aegean Islands, potentially facilitated by marine regressions.

Taxonomic Changes

A checklist of all described species of Philonthina, a subtribe of the staphylinid tribe Staphylinini, known to occur in Central and South America (CASA) is presented. Included for each species, and for synonyms known from CASA, is a reference to the original description, type locality and type depository, and for each species the known distribution within and outside CASA. Type material was sought in the main European and American collections where it is deposited (BMNH, MNHUB, IRSNB and FMNH) and is summarized for all indigenous CASA species, with lectotypes designated for 16 names and confirmation of holotypes and prior designation of lectotypes when necessary. Based on recent phylogenetic work in Philonthina and our revision of types of CASA species of Philonthus Stephens, 1829 and Belonuchus Nordmann, 1837, some taxonomic changes are proposed. Thirty-one species of Philonthus are transferred to Belonuchus (16), Gabrius Stephens 1829 (14), and Bisnius Stephens 1829 (one) resulting in the following new combinations: B. abnormalis (Sharp 1885), B. celatus (Sharp 1885), B. corticalis (Sharp 1885), B. extremus (Sharp 1885), B. infimus (Sharp 1885), B. iteratus (Sharp 1887), B. latecinctus (Sharp 1885), B. lucilius (Sharp 1885), B. muticus (Sharp 1876), B. optatus (Sharp 1885), B. platypterus (Sharp 1885), B. rufiventris (Sharp 1887), B. rufocaudus (Sharp 1885), B. rufopygus (Sharp 1885), B. serraticornis (Sharp 1876), B. supernus (Herman 2001), G. approximans (Sharp 1885), G. armatipes (Sharp 1885), G. atricolor (Sharp 1885), G. championi (Sharp 1885), G. dampfi (Bernhauer 1929), G. elegans (Sharp 1885), G. forsterianus (Scheerpeltz 1960), G. misellus (Sharp 1885), G. nugax (Sharp 1885), G. ovaticeps (Sharp 1885), G. peruvianus (Bernhauer 1916), G. planulatus (Sharp 1885), G. rusticus (Sharp 1885), G. serpens (Sharp 1885) and Bi. subaeneipennis (Bernhauer 1916). Endeius nitidipennis Solier 1849 is transferred to Gabrius, resulting in the following new combination, G. nitidipennis (Solier 1849). Leptopeltus carchiensis Chani-Posse & Asenjo 2013 is proposed as junior synonym of Philonthus divisus Sharp 1891, which is transferred to Leptopeltus Bernhauer 1906 resulting in a new combination: Leptopeltus divisus (Sharp 1891). Belonuchus penetrans Silvestri 1946 is transferred to Pridonius Blackwelder 1952 as a new combination. Lectotypes are designated for Atopocentrum mirabile Bernhauer 1906, Philonthus armatipes Sharp 1885, Ph. atricolor Sharp 1885, Ph. championi Sharp 1885, Ph. misellus Sharp 1885, Ph. planulatus Sharp 1885, Ph. rusticus Sharp 1885, Ph. serpens Sharp 1885, Ph. abnormalis Sharp 1885, Ph. celatus Sharp 1885, Ph. infimus Sharp 1885, Ph. latecinctus Sharp 1885, Ph. muticus Sharp 1876, Ph. platypterus Sharp 1885, Ph. rufocaudus Sharp 1885 and Ph. rufopygus Sharp 1885. Of the 543 currently known species of Philonthina reported from CASA, at least 14 are believed to be adventive from elsewhere, 56 may occur naturally elsewhere, and 473 (87%) are evidently endemic to this region. Of the 31 genera represented by these described species, 20 (65%) are endemic to CASA. One genus, Gabronthus Tottenham 1955, is adventive. However, the actual philonthine fauna of CASA will undoubtedly be much larger, and the generic composition highly modified, when the fauna is fully explored and studied within a phylogenetical framework.

Taxonomic Changes

Extant genera and subgenera of the Trogidae (Coleoptera: Scarabaeoidea) are reviewed. Contemporary classifications of this family have been based exclusively on morphological characters. The first molecular phylogeny for the family recently provided strong support for the relationships between morphologically defined genera and subgenera. On the basis of morphological, molecular and biogeographical evidence, certain taxonomic changes to the genus-level classification of the family are now proposed. The family is confirmed as consisting of two subfamilies, Omorginae Nikolajev and Troginae MacLeay, the former with two genera,OmorgusErichson andPolynoncusBurmeister, and the latter with two genera,TroxFabricius andPhoberusMacLeaystat. rev.Phoberusis restored to generic rank to include all Afrotropical (including Madagascan endemic) species;Afromorgusis confirmed at subgeneric rank within the genusOmorgus; and the monotypic Madagascan genusMadagatroxsyn. n.is synonymised withPhoberus.The current synonymies ofPseudotroxRobinson (withTrox),ChesasBurmeister,LagopelusBurmeister andMegalotroxPreudhomme de Borre (all withOmorgus) are all accepted to avoid creating speculative synonyms before definitive phylogenetic evidence is available. New combinations resulting from restoringPhoberusto a monophyletic genus are listed in Appendix A.

A survey of freshwater fungi on submerged wood in China and Thailand resulted in the collection of three species in Dictyocheirospora and four species in Dictyosporium including two new species in the latter genus. Morphological characters and phylogenetic analyses based on ITS, LSU and TEF1α sequence data support their placement in Dictyocheirospora and Dictyosporium (Dothideomycetes). An updated backbone tree is provided for the family Dothideomycetes. Descriptions and illustrations of the new taxa and re-collections are provided. Four new combinations are proposed for Dictyocheirospora.

Taxonomic Studies

Some neglected genera of Palearctic Eulophidae and Pteromalidae (Chalcidoidea) are reviewed as part of ongoing preparation of keys to identification of world genera of these families. Some of these genera are represented by distinctive species which properly belong to larger genera, and some were described based on misinterpreted morphological characters. Bryopezus Erdös syn. nov. is synonymized under Deutereulophus Schulz, Danuviella Erdös syn. nov. under Diglyphus Walker, Cleolophus Mercet syn. nov. and Parpholema Szelényi syn. nov. under Hemiptarsenus Westwood, Dubiostalon Szelényi syn. nov. under Neotrichoporoides Girault, and Dudichilla Szelényi syn. nov. under Syntomopus Walker. Deutereulophus brevipennis (Erdös) comb. nov., Diglyphus subplanus (Erdös) comb. nov., Hemiptarsenus autonomus (Mercet) comb. nov., Hemiptarsenus virescens (Storozheva) comb. nov., Neotrichoporoides inusitatus (Szelényi) comb. nov., Mesopolobus fuscus (Szelényi) comb. nov., Syntomopus crassicornis (Szelényi) comb. nov. are new combinations resulting from these changes. Two species are transferred to their proper genera: the brachypterous species Necremnus collaris (Szelényi) comb. nov. from Microlycus Thomson, and Mesopolobus fuscus (Szelényi) comb. nov. from Tricolas Bouček. Neanica Erdös is discussed as a distinct and valid genus within Pteromalinae, with comparison to other genera. The replacement name Hemiptarsenus collapsus nom. nov. is chosen for Parpholema collaris Szelényi, which becomes a junior homonym of Hemiptarsenus collaris (Ashmead). Reasons for taxonomic changes are discussed with reference to distinctive features shared with species in other genera. One newly discovered morphological feature is discussed, the prepectal bulge found in some Sphegigastrini (Pteromalidae). Photographs of type specimens are provided to facilitate future recognition of these species.

Inference Methods

A new wood-inhabiting fungal species, Gloeodontia yunnanensis, is proposed based on a combination of morphological features and DNA data. The species is characterized by an annual, resupinate basidiomata with smooth hymenial surface, a monomitic hyphal system with thin-walled, clamped generative hyphae and obclavate cystidia and subglobose to globose, hyaline, thick-walled, asperulate, strongly amyloid, acyanophilous basidiospores measuring 3.3–4.3 × 2.5–3.5 µm. Sequences of ITS and 28S gene regions of the studied samples were generated and phylogenetic analyses were performed with Maximum Likelihood, Maximum Parsimony and Bayesian Inference methods. The analyses based on ITS+28S sequences showed that G. yunnanensis nested in the Gloeodontia clade and formed a monophyletic lineage with strong support (100% BS, 100% BP, 1.00 BPP).

Taxonomic Changes

Systematic relationships among Laniatores have received considerable attention during the past few years. Many significant taxonomic changes have been proposed, particularly in the superfamily Gonyleptoidea. As part of this superfamily, the basalmost Stygnopsidae is the least known family. In order to propose the first total evidence phylogeny of the family, we produced four datasets: three molecular markers – partial nuclear 28S, mitochondrial ribosomal 16S, mitochondrial protein-encoding cytochrome c oxidase subunit I; and 72 morphological characters. With these data, we performed three different phylogenetic analyses: (1) Bayesian Inference with molecular data, and (2) Bayesian Inference and (3) Maximum Likelihood using combined data. Our results are congruent: a monophyletic Stygnopsidae subdivided into two major clades: Stygnopsinae and Karosinae, subfam. nov. The following genera are redefined: Stygnopsis, Hoplobunus and Serrobunus stat. rev. The following taxa are described: Iztlina venefica, gen. nov., sp. nov. and Tonalteca, gen. nov. Additionally, the following changes are proposed: Serrobunus queretarius (Šilhavý, 1974), comb. nov., Stygnopsis apoalensis (Goodnight & Goodnight, 1973), comb. nov., Stygnopsis mexicana (Roewer, 1915), comb. nov., Stygnopsis oaxacensis (Goodnight & Goodnight, 1973), comb. nov., and Tonalteca spinooculorum (Goodnight & Goodnight, 1973), comb. nov. We also discuss the status of the genera Isaeus stat. rev. and Mexotroglinus. Finally, we discuss the evolution of male genitalia and convergence of selected homoplastic diagnostic characters.

The Family

The flat wasps, Bethylidae, are cosmopolitan and one of the most diverse families of Chrysidoidea. Bethylidae have 2,920 described extant species and almost 90 fossil species. The oldest geological record of the family is the Lower Cretaceous, from Lebanese and Spanish ambers and Transbaikalian rock fossils. Here we describe and illustrate one new fossil subfamily of Bethylidae: †Elektroepyrinae subfam. nov. represented by †Elektroepyris Perrichot & Nel from the lowermost Eocene Oise amber (France), which was cladistically assessed against all other eight subfamilies of Bethylidae. The new taxon is easily distinguished from other subfamilies by the forewing venation with the third abscissa of Cu present. Phylogenetic analyses support the monophyly of all subfamilies of Bethylidae, with a matrix with 69 morphological characters and 22 terminal taxa from where †Elektroepyrinae subfam. nov. emerged as independent lineage from all other subfamilies.

Molecular and morphological phylogenetic analyses indicate that many of the perennial endemic genera of North American Apiaceae are either polyphyletic or nested within paraphyletic groups. In light of these results, taxonomic changes are needed to ensure that ongoing efforts to prepare state, regional, and continental floristic treatments of Apiaceae reflect recent findings. Thus, six new combinations are made to accommodate the movement of five taxa from their current assignment into the genus Lomatium and the elevation of one variety of Lomatium to the level of species; Lomatium lithosolamans, Lomatium tenuissimum, Lomatium fusiformis, Lomatium linearifolium, Lomatium multifidum, and Lomatium planosum.

Abstract The Chinese Panorpa species without anal horn are normally assigned to the Panorpa davidi group. Here, we taxonomically revise the P. davidi group, which currently includes 17 known species and four new species: P. gaokaii sp. nov., P. huayuani sp. nov., P. uncinata sp. nov. and P. yaoluopingensis sp. nov. Panorpa shanyangensis Chou & Wang, 1981 and P. sexspinosa zhongnanensis Chou & Ran, 1981 are treated as junior synonyms of P. sexspinosa Cheng, 1949. We describe for the first time the male of P. stigmosa Zhou, 2006, and the females of P. curva Carpenter, 1938, P. davidi Navás, 1908, P. difficilis Carpenter, 1938, P. fructa Cheng, 1949, and P. jinchuana Hua, Sun & Li, 2001. A key to species of the group is provided. Phylogenetic analyses of maximum parsimony and maximum likelihood based on 79 morphological characters show that the newly defined P. davidi group is a well-supported monophyletic group and is sister to the genus Cerapanorpa Gao, Ma & Hua, 2016.
