Two new species of pselaphine staphylinids in the genus Batrisodes are described: B. (Declivodes) dorothae Ferro and Carlton from Feliciana Preserve, Louisiana; and B. (Babnormodes) spretoides Ferro and Carlton from Great Smoky Mountains National Park, Tennessee. They differ from all other described Batrisodes species in secondary male characters, especially details of the frontal region of the head. These two species bring the total diversity of the genus in North America to 88 species. Specimens were imaged using light microscopy, scanning electron microscopy, and X-ray microtomography (micro-CT) techniques. Utility of multiple imaging techniques, especially micro-CT, is discussed.
Two new species and a new genus of Cerambycidae are described from South America: Cotyclytus arriagadai sp. nov., from Bolivia; and Lembu dieguezi, gen. nov., sp. nov., from Paraguay. Orthomegas irroratus (Lameere, 1915) is redescribed, based on the second and third known specimens, and its distribution is expanded to include Ecuador. The male of Jamesia fuscofasciata Dillon and Dillon, 1952 is described and illustrated for the fi rst time, and the distribution of the species is expanded to Peru. Thirty-two new country records (twelve for Paraguay, fi fteen for Peru, two for Ecuador, three for Bolivia) and one new province record (Argentina) are presented.
The aquatic biodiversity of springs and groundwater systems of North Africa remains largely unexplored. In an earlier field survey of Tunisian springs, a new gastropod genus, Bullaregia, was discovered as a phylogenetically independent lineage of uncertain position within the family Hydrobiidae. Here, we provide taxonomic and phylogenetic assignments for three newly collected populations of hydrobiids from springs in northern Tunisia based on morphological, anatomical and genetic (mtCOI and 18S) data. Among these and specimens of Bullaregia, major differences were observed in male and female genitalia as well as in mtCOI sequences (divergence 8.0–9.1%). Based on these findings, we describe two new genera and three new species: Belgrandiellopsis chorfensis gen. et sp. nov., Belgrandiellopsis secunda gen. et sp. nov. and Biserta putealis gen. et sp. nov. In all our phylogenetic analyses, these three new species were well resolved as a monophyletic group together with Bullaregia tunisiensis. Unexpectedly, this clade emerged as sister to the European valvatiform genera Corbellaria and Kerkia and not to the recently discovered clade of groundwater, conchologically similar, species living in Bulgaria (Balkan Peninsula). These Tunisian species are each locally endemic and form part of a newly discovered clade which in future systematic studies could eventually be identified as a distinct hydrobiid subfamily.
Adults of three known species of Ochodaeus Dejean (Coleoptera: Scarabaeoidea: Ochodaeidae) in Madagascar have a strongly granulate pronotum. Three new species are described herein that have a smooth or weakly granulate pronotum: Ochodaeus modopunctatus, O. polypollicatus, and O. meandrus. A key to the species of Ochodaeus from Madagascar is provided.
The salticid genera Bristowia Reimoser, 1934, Habrocestum Simon, 1876 and Macaroeris Wunderlich 1992 are reported from Sri Lanka for the first time. One new species of Bristowia, B. gandhii sp. nov. (♂♀), and three new species of Habrocestum, H. hantaneensis sp. nov. (♂♀), H. kodigalaensis sp. nov. (♂♀) and H. ohiyaensis sp. nov. (♂), are described and diagnosed. The male of Macaroeris nidicolens Walckenaer, 1802 is redescribed and illustrated, based on new material from Sri Lanka.
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 authors collected caddisflies in the Dabie Mountains in 2014 and 2015. Three species of Psilotreta Banks, 1899 were found: Psilotreta daidalos Malicky, 2000, P. furcata sp. nov., and
P. brevispinosa sp. nov. The species were collected by light sheet traps or hand nets near streams in mountainous forests. All the species are described and illustrated, and the species groups to which they belong are discussed. Some variation within P. daidalos is described and the species is newly recorded from the Anhui and Hubei Provinces.
The Indochinese to southern Chinese millipede genus Tylopus currently comprises 62 species, including eight new ones: T. flavolineatus sp. nov., T. hongkhraiensis sp. nov. from central and northern Thailand, respectively, T. moniliformis sp. nov., T. retusus sp. nov., T. acuminatus sp. nov., T. dorsalis sp. nov., T. thunghaihin sp. nov., all from Laos, and T. punctus sp. nov. from northern Myanmar. A new record of T. baenzigeri Golovatch & Enghoff, 1993, from northern Thailand is given. All these species are richly illustrated, and a modified key to all known species of the genus is also provided.
