RESUMO
Anaulacomera currently contains 147 valid species, of those 50 are recorded from Brazil. The genus is further divided into six subgenera, which can be distinguished on characteristics of the male terminalia. A new Brazilian species is presently proposed, Anaulacomera (Anallomes) curvata sp. nov., based on three males and one female collected at Parque Nacional de Itatiaia, Itatiaia, Rio de Janeiro State. It can be distinguished from all other species because of the pair of cerciform projections of the tenth male abdominal tergite and a combination of shape and size of the male cerci.

The status of the genus Phelene stat. resurr., previously synonymized under Chiriquia is revalidated. The genus is redescribed and Phelene turgida stat. rev. a lectotype and paralectotypes are designated for this species. Tetrix laticeps is proposed as nomen dubium and its described a new additional species Phelene maroon n. sp. The diagnosis of the subfamily is adjusted with the characters of the new taxa included and an updated key of genera and species is provided.

Raggophyllum Nickle, 1967 is a monotypic genus, including Raggophylluym spinosum, and recorded in Peru and Bolivia. In this work, Raggophyllum is redescribed and assigned to the Microcentrini, based on the type species Raggophylluym spinosum. Raggophyllum rubrofemoratum sp. nov. in described from Brazil, Acre and Amazonas, and it is the first record for the genus in Brazil. The male genitalia and the stridulatory file morphology are described for the first time. A distribution map, notes on the habitat, and commentaries on their distribution among Amazonian endemism areas are included.

The New World Jerusalem crickets currently consist of 4 genera: Stenopelmatus Burmeister, 1838, with 33 named entities; Ammopelmatus Tinkham, 1965, with 2 described species; Viscainopelmatus Tinkham, 1970, with 1 described species, and Stenopelmatopterus Gorochov, 1988, with 3 described species. We redefine the generic boundaries of these 4 genera, synonymize Stenopelmatopterus under Stenopelmatus, and synonymize Viscainopelmatus under Ammopelmatus. We then discuss, and illustrate, all the types of the species of Stenopelmatus, all of which only occur south of the United States' border. We recognize as valid the following 5 described Mexican and Central American species: S. ater, S. piceiventris, S. sartorianus, S. talpa, and S. typhlops. We declare the following 13 described Mexican and Central American Stenopelmatus taxa as nomen dubium: S. calcaratus, S. erythromelus, S. guatemalae, S. histrio, S. lessonae, S. lycosoides, S. mexicanus, S. minor, S. nieti, S. sallei, S. sumichrasti, S. toltecus, and S. vicinus. We designate a neotype for S. talpa and lectotypes for S. ater, S. guatemalae, S. histrio, S. lessonae, S. mexicanus, S. minor, S. nieti, S. sallei, S. sumichrasti, and S. toltecus. We assign a type locality for S. piceiventris. We concur with the previous synonymy of S. politus under S. sartorianus. We describe 14 new species of Stenopelmatus from Mexico, Honduras and Ecuador, based on a combination of adult morphology, DNA, calling song drumming pattern, distribution, and karyotype: S. chiapas sp. nov., S. cusuco sp. nov., S. diezmilpies sp. nov., S. durango sp. nov., S. ecuadorensis sp. nov., S. faulkneri sp. nov., S. honduras sp. nov., S. hondurasito sp. nov., S. mineraldelmonte sp. nov., S. nuevoleon sp. nov., S. perote sp. nov., S. saltillo sp. nov., S. sanfelipe sp. nov., and S. zimapan sp. nov. We transfer the following 16 described United States taxa, plus S. cephalotes from the "west coast of North America", from Stenopelmatus to Ammopelmatus: A. cahuilaensis, A. californicus, A. cephalotes, A. fasciatus, A. fuscus, A. hydrocephalus, A. intermedius, A. irregularis, A. longispinus, A. mescaleroensis, A. monahansensis, A. navajo, A. nigrocapitatus, A. oculatus, A. pictus, and A. terrenus, along with the Mexican taxon A. comanchus: these species will be discussed in a subsequent paper (Weissman et al. in prep). We believe that all new Jerusalem cricket species descriptions should include, at a minimum, calling drum (most important) and DNA information.

Species of Temnomastax have wide morphological similarities, and differentiation is usually based on male and female genitalia. In this study, we tested whether morphometric differences contribute to differentiation of species of Temnomastax, proposed an identification key for males, and morphometrically studied the sexual dimorphism of Temnomastax hamus and Temnomastax ricardoi. Analysis was performed using 204 specimens belonging to six species; fifteen morphometric variables were used. We used MANOVA and ANOVA to test the morphometric differences among species and Discriminant Analysis for sexual distinction. Temnomastax sp. nov. 1 had the highest values in â of all analyzed variables used for morphometric distinction of males, followed by Temnomastax latens, T. ricardoi and Temnomastax sp. nov. 2, and T. hamus and Temnomastax tigris. Two groups were formed by the MANOVA, with length of body, length of hind femur, and length of tegmen as the main variables that distinguished them. Overall, females of T. hamus and T. ricardoi presented higher averages for measurement values used in morphometric distinction between sexes than conspecific males and based on discriminant analysis we found significant differences between sexes. There are significant differences in morphometric variations and the ratio between body length and tegmen length provided reliable evidence for differentiation among species, which can be used as a valid tool that complements the identification of Temnomastax species.

The tribe of the giant katydids Steirodontini is reviewed, its relationship with other groups of Phaneropterinae from the Old and New World is discussed, and an updated key to genera is presented. Nicklephyllum n. gen. is established to accommodate one species described as Stilpnochlora acanthonotum Nickle, 1985 from Colombia. Cnemidophyllum tani n. sp. from the Colombian Amazon is described. Another new combination and two synonymies are proposed: Steirodon (Frontinus) emsleyi (Piza, 1979) n. comb., Steirodon (Posidippus) parastahli Piza, 1979 n. syn. (of Steirodon (Steirodon) ponderosum Stål, 1873), and Steirodon (Posidippus) tricenarius (Piza, 1974) n. syn. (of Steirodon (Frontinus) rufolineatum Emsley, 1970). Finally, Steirodon (Posidippus) rarospinulosum (Brunner von Wattenwyl, 1891), only known from Peru, is reported from the Colombian Amazon.

The first record of the Orthoptera species Lerneca inalata for Brazil is presented here. The taxon is represented by a new subspecies Lerneca inalata beripocone subsp. nov. (Phalangopsidae, Luzarinae), collected in the Pantanal of Poconé, Mato Grosso, Brazil. This work includes morphological and morphometric data as well as descriptions of female genitalia and calling song. The new subspecies has as diagnostic features the male genitalia with six ventral spines on the B sclerite, the first spine having a subtle bifurcation; the mid-region of the strongly sclerotized pseudepiphallus; inclination of C sclerite with slightly concave curvature; tegmina-length ratio and the speculum (syn. mirror) width approximately three times the length of the apical area. The description of the female genitalia and the calling song is presented for the first time for the species Lerneca inalata. A distribution map covers the local occurrence of its subspecies.
