The female of Leptagrion jeromei Lencioni, Vilela & Furieri, 2021 is described, illustrated, and diagnosed based on a specimen collected in epiphytic bromeliads at the Federal University of Sergipe ( (B0545), BRAZIL, Federal University of Sergipe, So Cristvo, -10.92707, -37.10100, 30 m asl, 6.x.2023, A.B.S. Farias & J.C. Santos leg.). Additionally, we provide information on its biology, ecology, and taxonomic notes, along with illustrations of the collected males.

Odontogryllini is a tribe of ground-dwelling crickets exclusive to America. After several taxonomic rearrangements, this tribe has five genera and 23 species now placed in the subfamily Landrevinae. These crickets have dorsoventrally depressed bodies and are moderately to densely covered with bristles. The males may bear tegminal, metanotal, or tergal glands. In this contribution, we discuss the taxonomic status and the morphological features of Odontogryllini and the other two tribes of Landrevinae: Landrevini and Prolandrevini. The presence of dorsal spines between the outer spurs of the hind tibia distinguishes Odontogryllini from Prolandrevini, and the straight or slightly arcuate but never S-shaped stridulum from Landrevini. We also propose the enlarged and plate-like rami as a diagnostic characteristic to distinguish Odontogryllini from Landrevini. Additionally, we describe a new species of the genus Xulavuna de Mello & Campos from the Brazilian Amazon Rainforest, named Xulavuna krenakore sp. nov..

Chaetophloeus flourensiae new species, is described from the Chihuahuan Desert from Arizona and western Texas and Hylocurus incognitus new species is described from Texas, Oklahoma and Louisiana. New synonymies include: Chramesus mimosae Blackman, 1938 (= Chramesus varius Wood, 1969); Hylocurus rudis (LeConte, 1876) (= Hylocurus binodatus Wood, 1974; Hypothenemus seriatus (Eichhoff, 1872) (= Stephanoderes multidentatus Hopkins, 1915, Stephanoderes nitidifrons Hopkins, 1915, Hypothenemus hopkinsi Browne, 1963); Hypothenemus pubescens Hopkins, 1915 (= Hypothenemus sparsus Hopkins, 1915, Hypothenenus similis Hopkins, 1915, Stephanoderes tridentatus Hopkins, 1915); Phloeotribus scabricollis Hopkins, 1916 (=Phloeotribus pseudoscabricollis Atkinson, 1989; Pseudothysanoes yuccae (Wood, 1956), (=Pseudothysanoes yuccavorus Wood, 1971); and Thysanoes texanus Blackman, 1943 (=Thysanoes mexicanus Wood, 1956). Hylocurus schwarzi Blackman, 1928, is redescribed including the first description of the female. New locality and host records that significantly extend the respective ranges are included for 30 species from the border region of the United States and Mexico.

Dentoluzara spatulatus n. gen. et n. sp., from the middle lands of the Colombian Andes, is described. This new phalangopsid cricket is distinguished by its asymmetrical mandibles with a basal prolongation in the left one, which is why it is recorded as the first Tusked Cricket. This rare morphological structure has only been observed in some species of anostostomatids and a couple of genera of tettigoniids, but never in crickets. Furthermore, D. spatulatus n. gen. et n. sp., has the ps. p2, from the male genitalia, spatula-shaped, deriving its specific epithet from there. Finally, the new genus peculiar mandibular morphology and the subfamily Luzarinaes taxonomy are commented and discussed.

We describe here a new species of terrestrial earthworm Eutyphoeus rihnimensis sp. nov. (family Acanthodrilidae) from specimens collected at Khawrihnim, a village in Mizoram, Northeast India. The new species is distinguished from its congener members in E. gigas group in having an outgrowth that branches into four finger-like projections from the male porophores, five pairs of supra-intestinal glands in 8188 segments, typhlosole that begins from segment 25, ventral intestinal caeca 10 that covers segments 33-34, a bidiverticulate spermathecae with a short and stout duct, and very short lateral and median diverticula among other characters. Sequence analysis based on mitochondrial cytochrome c oxidase subunit 1 (CO1) gene further warrants its distinction from known species of Eutyphoeus.

Two new species, Repetekiodes serratalis sp. nov. and Repetekiodes turanella sp. nov. are described from Central Asia. The described species are well distinguished from their congeners by the genitalia and forewing pattern. A brief overview of the genus Repetekiodes Amsel, 1961 is given and original data on the distribution of Repetekiodes species are provided. DNA barcode data are presented for several species of the genus.

Aberrations involving the metasoma in Hymenoptera are well-documented, with one notable teratological case being the fusion of metasomal terga, named symphysomery. This aberration, characterized by the fusion of the second and third terga, has been observed in various species groups of Hedychridium, spanning from Southern Africa to Central Asia. Similar aberrations were noted in Prochridium Linsenmaier from Mongolia and Anachrysis Krombein from Southern Africa. The monotypic genus Oligogaster Soliman & Kimsey is distinguished by two visible metasomal terga. However, the sole specimen of Oligogaster kimseyae Soliman, the type species of the genus, is here considered an aberrant specimen affected by symphysomery, exhibiting the fusion of the second and third metasomal terga. Consequently, Oligogaster Soliman & Kimsey is here synonymized with Hedychridium Abeille de Perrin.

Bronchocela celebensis Gray, 1845 is one of the rarest species of the genus, known only from less than 20 museum specimens collected from northern Sulawesi. It is often confused with its similar congener, B. cristatella, which occurs widely throughout the Indonesian Archipelago and Peninsular Malaysia, except on the Sulawesi mainland. Here, we examine the morphology of B. celebensis based on 46 museum specimens including freshly collected individuals, and redescribe the species based on the holotype (by monotypy). We studied the characters of B. celebensis with morphometric comparison to its allopatric congener B. cristatella from the adjacent islands of southern Sulawesi in Indonesia. Based on the current distribution pattern and the apparent threats, we update the conservation status of B. celebensis using the IUCN Red List Criteria and propose that it be considered as a Vulnerable (VU) species endemic to Sulawesi.

A new species of Itara (Phormincter) is described from Mindanao in the Philippines: Itara (Phormincter) mindanao Tan, Grumo, Gono & Bahoy, sp. nov. This represents the first record of this subgenus in the Philippines, having previously known only from Borneo, Java, Malay Peninsula and Sumatra; as well as only the second species of Itara known from the Philippines and the first from Mindanao Island. The male calling song of the holotype was also recorded and is described here. Additionally, the male calling song of another congener, Itara (Singitara) singularis Gorochov, 1997 from Sabah, is described here. A new species of Itara (Bornitara) is also described from Sabah in Borneo: Itara (Bornitara) tenompok Tan, Japir & Chung, sp. nov.

Lankascincus fallax is an endemic, but widespread species of skink distributed throughout Sri Lanka, including all bioclimatic zones (elevations from 0 to 1,200 m a.s.l.). After thoroughly comparing morphology and morphometry between populations in different bioclimatic zones, we recognize it as a single morphospecies. We revise the systematics of Lankascincus fallax based on molecular and morphological data providing a comprehensive re-description of the adult syntype collected from either Ratnapura or Trinkomalee (sic), Sri Lanka. We provide the first-ever constructed phylogeny of Lankascincus representing five species (out of nine) based on GenBank data. In addition, we examined all the type specimens of the two synonymized species, Sphenomorphus rufogulus and Lankascincus deraniyagalae. We also provide a comprehensive discussion on the distribution of L. fallax.
