Synopsis of the genus Pseudoperma Dillon and Dillon, 1946 (Coleoptera: Cerambycidae), with description of a new species

A synopsis of Pseudoperma is provided. This genus mainly differs from Onocephala and Stethoperma by the antennal tubercles well separated; antennae relatively short, in the female subequal to the body length; and scape and third antennomere subequal in length. Pseudoperma includes two species, P. chalcogramma (Bates, 1887) and P. patruelis (Breuning, 1940), both from Brazil; herein we describe one new species, Pseudoperma lingafelteri sp. nov. from Brazil (Rio de Janeiro). This species differs from its congeners mainly in having the frons and occiput covered with greyish pubescence, and the sides of the elytra with several interrupted or coalescent vittae. We provide new distribution data for Pseudoperma patruelis (Breuning, 1940) from Brazil, Minas Gerais, São Paulo and Santa Catarina, as well as illustrations and a key to the species of Pseudoperma.

The Neotropical genus Cyriocosmus Simon, 1903 and new species from Peru,Brazil and Venezuela (Araneae: Theraphosidae: Theraphosinae)

Cyriocosmus peruvianus sp. nov., C. itayensis sp. nov., C. aueri sp. nov., C. giganteus sp. nov. from Peru, Loreto region, C. hoeferi sp. nov. from Brazil, C. williamlamari sp. nov. and C. nicholausgordoni sp. nov. from Venezuela are described, illustrated, diagnosed and both sexes, if known, keyed. New Peruvian species can be distinguished from all congeners, except C. bertae Pérez-Miles, 1998 and C. pribiki Pérez-Miles and Weinmann, 2009, by the uniformly coloured carapace and abdomen without stripes and by the short paraembolic apophysis in male palpal bulb. The female of Cyriocosmus ritae Pérez-Miles, 1998 is described for the first time from a known Peruvian population near Iquitos.

Additional new species of Grouvellinus Champion 1923 (Insecta,Coleoptera, Elmidae) discovered by citizen scientists and DNA barcoded in the field applying a novel MinION-based workflow

ABSTRACT

Four new species, Grouvellinus nigerquadratus sp. nov., G. cruxniger sp. nov., G. luciaensis sp. nov., and G. borneensis sp. nov., are described from Borneo and illustrated in detail. Two additional species of the genus which remain undescribed are briefly diagnosed. The material was collected during Taxon Expeditions’ field course which involved citizen scientists, students and taxonomists. Specimens were collected at altitudes between 270 m and 750 m above sea level using fine-meshed hand-nets and blacklight traps. The morphological species delimitation based on morphology was supplemented and congruent with mtDNA sequences which are the first DNA barcodes for the genus from Borneo. They were obtained in the field using a newly developed rapid and accurate MinION-based workflow. The inter – and intraspecific genetic distances and the problems regarding cryptic species delimitation are discussed.

The first Hapalotremus Simon, 1903 (Araneae: Theraphosidae) from Argentina: description and natural history of Hapalotremus martinorum sp. nov.

A new species of Hapalotremus Simon, 1903 from northern Argentina is described and illustrated. Hapalotremus martinorum sp. nov. differs from all other congeners by the colour pattern of live specimens. Males differ in the male palpal bulb morphology, with thickened and less curved embolus having a blunt subapical keel and less-developed apical keel. Females differ in the shape of the spermathecae, with the lateral bases more pronounced than the superiors and the upper edge more rounded. Specimens were captured inhabiting short burrows or crevices under stones in high cloud forests. Hapalotremus cyclothorax (Mello-Leitão 1923) is a junior synonym of Homoeomma montanum (Mello-Leitão, 1923), Hapalotremus scintillans (Mello-Leitão 1929) is a junior synonym of Pachistopelma rufonigrum Pocock, 1901, Hapalotremus exilis (Mello-Leitão 1923) and Hapalotremus muticus (Mello-Leitão 1923) are considered species inquirenda.

A new Chilean genus and species of land planarian (Platyhelminthes: Tricladida,Geoplaninae) with cephalic retractor muscle and adenodactyl

ABSTRACT

A new genus and species of land planarian, Pichidamas piru gen. nov. sp. nov., is described from Pichidamas, province of Osorno in Southern Chile. Pichidamas piru is a sub-cylindrical and slender Geoplaninae characterized by the presence of a creeping sole extending 50% of the body width, a cephalic retractor muscle, five parenchymatic muscle layers, a male atrium with proximal tongue-like fold and distal adenodactyl; and ovovitelline ducts approaching the copulatory apparatus anteroventrally. Details of the organization of the cephalic retractor muscle, the absence of sensory pits, the existence of a parenchymatic muscle layer, located to the inside of the ventral peripheral nervous plexus, and an adenodactyl in the distal portion of the male atrium are unique traits seemingly reflecting an earlier branch of Geoplaninae.http://www.zoobank.org/urn:lsid:zoobank.org:pub:04423258-DB01-4CE3-A474-EF6B563C605C     

Genus Pseudolepturges Gilmour (1957) (Coleoptera: Cerambycidae: Lamiinae): a new species from Bolivia,key to the species of the genus and first reports of a possible Pseudomyrmex ant mimic in longhorn beetles

A new species of Pseudolepturges from Bolivia is described and illustrated; a key to the species is also provided. Based on the similar body size, orange-yellowish colour, behaviour, and close co-occurrence on a Triplaris americana tree, we suggest that Pseudolepturges triplarinus sp. nov. is a mimic of the ant Pseudomyrmex triplarinus.

Synopsis of the genus Ecoporanga Napp and Martins (Insecta: Coleoptera: Cerambycidae)

Two new taxa are described: Ecoporanga cooperi sp. nov. from Peru (Amazonas) and Ecoporanga wallacei sp. nov. from Ecuador (Tungurahua). The former differs from other species of the genus by the antennae and black legs and green elytra with metallic reflections. Ecoporanga wallacei differs from the other species by well-marked posterolateral depressions and tubercles near posterior margin of the pronotum, and apex of elytra laterally with recurved spine. A key to species of the genus is provided.

The type species of the bee genus Epicharis Klug, 1807 (Hymenoptera: Apidae)

Modern authors have treated Lutz and Cockerell’s indication of Centris umbraculata Fabricius, 1804 as the first valid type-species designation for Epicharis Klug, 1807. It is argued here, however, that Epicharis dasypoda Klug, 1807, junior synonym of Apis rustica Olivier, 1789, is the valid type species of Epicharis, as designated by Desmarest, in the article on Epicharis published in 1845 in volume 5 of d’Orbigny’s Dictionnaire Universel d’Histoire Naturelle. This overlooked designation makes Epicharana Michener, 1954, and not Xanthepicharis Moure, 1945, a junior synonym of Epicharis s.str. Therefore, Xanthepicharis should be revalidated for the group containing Epicharis umbraculata (Fabricius, 1804) and related species.

Review of the Neotropical genus Physiomorphus Pic (Coleoptera: Mycteridae: Lacconotinae), with description of the larvae of three species

The Neotropical lacconotine genus Physiomorphus Pic (Coleoptera: Mycteridae) is reviewed, and redescribed. Larvae are described and illustrated for three species, based on reared specimens. Detailed information is included on biology, rearing and habitat. New synonymies presented are: Physiomorphus Pic 1917 = Batobiomorphus Pic 1920; Laccoderus melanurus Champion 1916 = Batobiomorphus laticollis Pic 1920; Physiomorphus atricolor Pic 1917 = Physiomorphus rufotinctus Pic 1921. The following new species are described: Physiomorphus rufolineatus; P. antennatus; P. angustus; P. mimeticus, and P. subcostulatus, bringing the total number of known species to eight. Comparisons are made between larvae and adults of Physiomorphus and other described lacconotines. Details are given on Brazilian localities where Physiomorphus larvae were collected.     

Chilarboreus gen. nov., a new genus of Chilean Scirtidae (Coleoptera: Scirtoidea), with descriptions of three new species

The genus Chilarboreus gen. nov. is described from Nothofagus forests of Chile to accommodate three new species: Chilarboreus fossulatus sp. nov., Chilarboreus acuticollis sp. nov. and Chilarboreus darwini sp. nov. The genus is subdivided into two subgenera: Chilarboreus subgen. nov. (type species: C. fossulatus) and Pictarboreus subgen. nov. (type species: C. darwini). Identification keys to the genera of Chilean Scirtidae and the species in the genus Chilarboreus are provided. The state of knowledge of Chilean Scirtidae is summarized. The position of Chilarboreus within Scirtidae and the phenomenon of wing reduction in Scirtidae are discussed.     

The genus Eurycercus Baird, 1843 (Cladocera: Eurycercidae) in the Neotropics

In Brazil and Columbia, we found three different species of Eurycercus Baird, 1843 (Cladocera: Eurycercidae), belonging to two different subgenera: (1) E. (Eurycercus) cf. lamellatus (O. F. Müller, 1776), (2) E. (Bullatifrons) meridionalis sp. nov. and (3) E. (Bullatifrons) dumonti sp. nov. Appearance of the first species in Brazil could be a result of introduction due to human activities. The two other species are apparently Neotropical endemics. There is no opportunity to associate the previously described E. lamellatus var. minuta Birabén, 1939 Birabén, M. 1939. Los Cladóceros de la familia Chydoridae. Physis, 17: 651–671.  [Google Scholar] with any taxa found by us, because the type material is lost and no eurycercids are present in its type locality now; therefore this taxon is species incorrigenda with minimal chance of being re-evaluated.
