The monophyly of Theraphosinae is supported by both morphological and molecular phylogenies. However, intergeneric relationships often show polytomies and branches with low support. A previous phylogenetic study proposed an intergeneric relationship for the subfamily based on molecular data and divided it into three tribes: Grammostolini, Hapalopini and Theraphosini. However, not all genera of Theraphosinae were sampled, and some relationships were inferred based on morphological similarities. Regarding the Hapalopini from Brazil, the relationships of some genera are still uncertain, such as Kochiana, Catanduba, and Munduruku. In this paper, we describe four new species of Hapalopini from Brazil: Cyriocosmus paresi sp. nov., Hapalopus akroa sp. nov., H. guidonae sp. nov., and K. fukushimae sp. nov. In addition, we propose an updated diagnosis for these three genera and for the species K. brunnipes and M. bicoloratum.

A new species of Liolaemus is described from southwest of the town of Añelo, Neuquén Province, Argentina. Integrative evidence methodology of external morphological characters and molecular phylogenetic analyses of mitochondrial DNA (cyt-b) is used to place the new species to the species group of Liolaemus boulengeri. The new species is phenotypically close to L. mapuche. The new Liolaemus is medium to large in size (males 77.64–83.98 mm, females 72.88–78.58 mm), with evident sexual dichromatism. Genetic distances of the mtDNA (cyt-b) between the new species and its closest relative species are greater than 3% (L. cuyanus 7.48–12.02%; L. josei 7.56–9.60%; L. puelche 8.23–9.93%; L. mapuche 8.51–9.79%). Molecular and morphological phylogenetic results show L. mapuche as the sister species of the new one. The new species is larger than L. mapuche. Dorsal and ventral scales are more numerous in the new species than in L. mapuche, precloacal pores in females are present in L. mapuche and absent in the new species. It has strict psammophilic habits, using sand mounds and sheltering, under Alpataco (Neltuma alpataco) bushes. The L. boulengeri group now contains 75 species distributed in Argentina, Bolivia, Brazil, Chile, Paraguay, Peru and Uruguay.
The genera Aneflomorpha Casey, 1912 and Neaneflus Linsley, 1957 (Coleoptera: Cerambycidae) are revised for the species occurring in the United States. Examination of all primary types has necessitated redefinition of several species that were defined originally and subsequently on erroneous character descriptions. Two new species of Aneflomorpha are described from Arizona: Aneflomorpha crypta Lingafelter, new species and A. paralinearis Lingafelter new species. One subspecies, Aneflomorpha rectilinea yumae Giesbert and Hovore, 1976 is elevated to species, new status. Six species are synonymized: Aneflomorpha citrana Chemsak, 1960 is a new synonym of A. rectilinea Casey, 1924; Aneflomorpha parowana Casey, 1924 is a new synonym of Aneflomorpha linearis (LeConte 1859), along with its synonyms A. testacea Casey, 1924, A. elongata Linsley, 1936, and A. californica Linsley, 1936; Aneflomorpha arizonica Linsley, 1936 is a new synonym of Aneflomorpha unispinosa Casey, 1912; Aneflomorpha parkeri Knull, 1934 is a new synonym of Aneflomorpha gilana Casey, 1924; Aneflomorpha texana Linsley 1936 is removed from synonymy with A. seminuda Casey, 1912 and found to be conspecific with A. werneri Chemsak, 1962, new synonym. Aneflomorpha opacicornis Linsley, 1957 is transferred to Neaneflus as N. opacicornis (Linsley), new combination, and Neaneflus brevispinus Chemsak, 1962 is a new synonym. With this revision, there are eighteen species of Aneflomorpha and two species of Neaneflus recognized for the United States. All species are presented with new diagnoses, illustrated characters, updated distributional and host information, and an illustrated identification key.

Four new species of the spider genus Physocyclus Simon, 1893 are described from Mexico. Two species are described based on male and female adult specimens: Physocyclus mariachi sp. nov. and P. sikuapu sp. nov. Two species are described only with female adult specimens: P. lyncis sp. nov. and P. pocamadre sp. nov. The biogeographical province with the highest diversity of species is the Balsas Depression, located in the Mexican Neotropic, with 12 species. Physocyclus lyncis sp. nov. belongs to the dugesi species group, whereas the other three new species belong to the globosus species group. The total number of species of Physocyclus is increased to 37, distributed in North America (mainly Mexico) and Central America, with one cosmopolitan species: P. globosus. Updated taxonomic identification keys for males and females are provided.
An interesting new taxon of scarabaeoid beetle is described from western Texas, USA.

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.
A new genus, Cicatrisphaerion Lingafelter, Morris, Skillman, and Santos-Silva (Coleoptera: Cerambycidae), and three new species of the same authorship, C. wappesi from Quintana Roo, Mexico, C. rileyi from Chiapas, Mexico, and Eupogonius wappesi from Quintana Roo, Mexico, are described. New records and clarification on the distribution of Psyrassaforma janzeni Chemsak, 1991 and P. nitida Chemsak, 1991 are provided. Ameriphoderes amoena (Chemsak and Linsley, 1979) is redescribed based on four male specimens and a new country record from Guatemala is documented. New distributional records are provided for Estola flavobasalis Breuning, 1940 (including a new country record for Bolivia) and Estola vittulata Bates, 1874. A redescription and new distributional record are provided for Eupogonius flavovittatus Breuning, 1940 based on a female specimen.
Nothochodaeus marsupialis Paulsen, new species (Coleoptera: Ochodaeidae), is described from Aceh Province, Indonesia, on the island of Sumatra. The species possesses deep abdominal cavities behind a shield-like central process, as well as rows of conical tubercles laterally on the second and third ventrites. These structures have not been found in any other members of the genus or family.
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 species Canthidium alvarezi Martínez and Halffter, 1986 (Coleoptera: Scarabaeidae: Scarabaeinae) is transferred to the genus Ateuchus Weber, 1801, becoming Ateuchus alvarezi (Martínez and Halffter), new combination. Its relationship with other species in the genus is briefly discussed. The validity and ranking of the genus Lobidion Génier, 2010, originally described from a single female, is discussed based on the discovery of male specimens, which lead us to reclassify it as a monotypic subgenus of Ateuchus, becoming Ateuchus (Lobidion), new rank, with the only included species becoming Ateuchus (Lobidion) punctatissimus (Génier, 2010) new combination.
