Two new genera and six new species of flat mites (Prostigmata: Tenuipalpidae) from Goodeniaceae (Asterales) in Australia

JENNIFER J. BEARD — 2025-05-21

We describe two new genera, Goodeniacarus gen. nov. and Inglacarus gen. nov., based on five and one new species, respectively: Goodeniacarus leiperi sp. nov., G. reticulatus sp. nov., G. rosulatus sp. nov., G. uri sp. nov., G. wondul sp. nov.; and Inglacarus jonesi sp. nov. These represent a radiation of flat mites on the primarily Australian plant genus Goodenia (Goodeniaceae). Both new genera show strong affinities with the enigmatic genus Amblypalpus, but we argue that the new genera are a convergently regressive lineage with likely sister groups elsewhere within the Tenuipalpidae. We provide a key to these new species.

**Expanded morphological description of the Pawang Bent-toed Gecko Cyrtodactylus disjunctus of Thailand and a new country record for Malaysia**

MOHD ABDUL MUIN MD AKIL — 2025-05-21

Reported here is the first record of Cyrtodactylus disjunctus from Peninsular Malaysia. The specimen was collected in a limestone forest at Tasik Meranti, Perlis, approximately 13 km southeast of its type locality in Thailand. The specimen is an adult male which provides us the opportunity to not only add to the variation of this species but document sexually dimorphic characters. This report underscores how much remains undiscovered, even in areas as well-surveyed as Perlis State Park.

Uncovering Brazilian Otiocerinae (Hemiptera: Fulgoromorpha: Derbidae): description of three new species and first records for the tribes Sikaianini Muir, 1913 and Patarini Emeljanov, 1995

MURILO VICTOR SILVA BITAR — 2025-05-21

Despite the subfamily Otiocerinae being the largest in Derbidae by a great margin, there was only one recorded species in Brazil to date. A survey conducted by the authors at the Coleção Entomológica Padre Jesus Santiago Moure of the Universidade Federal do Paraná (UFPR) revealed a considerable number of undescribed Brazilian otiocerines, as well as other derbid species. Here, we describe three new species of Brazilian Otiocerinae: Mula flamma sp. nov., from Mato Grosso State; Otiocerus shamshir sp. nov., from Paraná State; and Patara paladinae sp. nov., from states of Paraná and Santa Catarina. Each species belongs to a different subtribe: Sikaianini Muir, 1913, Otiocerini Muir, 1917, and Patarini Emeljanov, 1995, respectively. The wing venations are described in detail, and hypotheses regarding vein identity are discussed.

**A contribution to the Odonata fauna of Moala Island, Fiji. Part I: erection of three new species in genera Nesobasis Selys, 1891 and Nikoulabasis Ferguson et al., 2023 (Odonata: Coenagrionidae)**

MILEN MARINOV — 2025-05-21

This study records the first members of Nesobasis Selys, 1891 and Nikoulabasis Ferguson et al., 2023 from Moala Island, Fiji. Three new species were erected for the following endemics: Nesobasis delai, sp. nov. (holotype male, headwater system, a tributary of Waitabu Lake), Nesobasis malokuensium, sp. nov. (holotype male, tributary of Wailevu Creek above Maloku village) and Nikoulabasis pauta, sp. nov. (holotype female, section of Wailevu creek about 500 m above Maloku village up to the Savukaratu waterfall). Three discussion points are outlined for future studies: phenology, female bias sexual ratio and biogeography.

**New data on Asianopis (Aranei: Deinopidae) in Southeast Asia**

MIKHAIL M. OMELKO — 2025-05-21

Three new species, Asianopis lini sp. nov. (♂), A. naumenkoi sp. nov. (♀), and A. apo sp. nov. (♀) are described from Malaysia (Borneo), and Philippines (Luzon, Mindanao). Asianopis liukuensis (Yin, Griswold & Yan, 2002) is reported from Borneo for the first time and its male redescribed. The record of the A. liukuensis is the easternmost for its whole range. A new species group, the Asianopis apo-group, is proposed. Detailed descriptions, digital photographs and a distributional map are provided.

**On the genus Megabahita Linnavuori & DeLong, 1978 (Hemiptera: Cicadellidae): new species, redescriptions, key to species, and a synonymy**

BEATRIZ M. CAMISÃO — 2025-05-21

The Neotropical genus Megabahita is reviewed and redescribed. A new species from Minas Gerais, Brazil, is described and illustrated. Megabahita cipoensis sp. nov. can be distinguished by the male pygofer without dorsal processes and with ventral processes spatulate, and the aedeagus with atrium relatively robust and without apical processes. Megabahita gigantea Linnavuori & DeLong, 1978 is redescribed and illustrated. Megabahita stylata DeLong, 1984 is considered a junior synonym of Sanestebania rotundiceps Linnavuori & DeLong, 1978, syn. nov. Megabahita patula DeLong, 1982 is transferred to Frequenamia, making the new combination Frequenamia patula (DeLong) comb. nov. A taxonomic key to species of Megabahita is provided for the first time.

On a collection of stomatopod Crustacea in the Fishery Survey of India, research cruises from the northeast coast of India

KRISHNAN SILAMBARASAN — 2025-05-21

The stomatopod fauna in Indian waters is relatively well documented, with 76 species recorded to date. This report is based on collections from exploratory fishery resources surveys conducted by the Fishery Survey of India during research cruises from 2019 to 2020. A total of 14 species were recorded during these surveys along the northeast coast of India. Among these, four species are reported as new records for the region: Clorida bombayensis (Chhapgar & Sane 1967), Carinosquilla lirata (Kemp & Chopra, 1921), Lophosquilla tiwarii Blumstein, 1974 and Squilloides leptosquilla (Brooks, 1886).

**Further additions to the rare dark sac spider genus Messapus Simon, 1897 (Araneae: Corinnidae)**

CHARLES R. HADDAD — 2025-05-21

In this paper, a new species of the spider genus Messapus Simon, 1897 is described, M. mygaloides sp. nov. (♀ ♂, Mozambique and Tanzania). We also provide the first description of the male of M. tigris Haddad & Mbo, 2015 based on a specimen collected from the type locality and record the species from Zimbabwe for the first time too. The type species, M. martini Simon, 1897, is recorded from Eswatini for the first time. An updated identification key to the genus is also presented.

**A new landhopper, Manawataawhiorchestia uruone gen. nov., sp. nov. (Amphipoda: Talitroidea: Talitridae) from Manawatāwhi/Three Kings Islands, New Zealand**

ALAN A. MYERS — 2025-05-21

A new genus and species of landhopper in the family Talitridae, Manawataawhiorchestia uruone gen. nov., sp. nov., is here described from the Three Kings Islands, New Zealand. Until recently, all native landhoppers in New Zealand had been attributed to the family Makawidae. Following the transferral of Dallwitzia simularis (Hurley, 1957) to the Talitridae Manawataawhiorchestia uruone gen. nov., sp. nov. becomes the second species of talitrid landhopper identified from New Zealand. All other New Zealand species in the family Talitridae have been classified as beachhoppers and sandhoppers.

**Description of the last instar larva of Acanthallagma caeruleum Williamson & Williamson, 1924 (Odonata: Coenagrionidae)**

KAREN LINEKE ALVAREZ-ALVAREZ — 2025-05-21

The last larval instar of Acanthallagma caeruleum Williamson & Williamson, 1924 is described and illustrated for the first time based on a reared female collected in the Colombian Amazon region (Caquetá department). This is the first larva known for this genus. The general aspect of the larva resembles that of some Oxyagrion Selys, 1876 and Acanthagrion Selys, 1876 species and presents the following unique combination of features: 1 pair of premental setae, stout spines mounted on elevated sockets in body and legs, caudal lamellae lanceolate and 0.86–0.90 the length of abdomen, with marked nodus and sulcus.

Shanaya: A new leafhopper genus of the tribe Mukariini (Cicadellidae: Deltocephalinae) with two new species discovered and described from India

NERNAKALLU N. RAJGOPAL — 2025-05-21

A new genus, Shanaya gen. nov., is proposed within the tribe Mukariini, based on the discovery of two new species from India that could not be assigned to any previously described genera. Detailed morphological descriptions and photographic illustrations are provided for both species: Shanaya spatulata gen. et sp. nov. (Type species, India: Himachal Pradesh) and Shanaya abeeri gen. et sp. nov. (India: Karnataka). Morphological evidence supports their classification under this new genus. A distribution map, along with identification keys to the genera of Mukariini of India and species of the new genus, are included. Its tribal placement, as well as similarities and differences with related genera, are also discussed. DNA barcodes (partial mitochondrial COI sequences) were generated for Shanaya spatulata gen. et sp. nov. and submitted to NCBI GenBank. All type specimens are housed in the National Pusa Collection (NPC), ICAR–Indian Agricultural Research Institute, New Delhi, University of Agricultural Sciences, Bengaluru (UASB) and National Insect Museum, ICAR–National Bureau of Agricultural Insect Resources, Bengaluru (NIM).
