**Eight new species of Yoyetta Moulds (Hemiptera: Cicadidae: Cicadettinae) from eastern Australia**

LINDSAY W. POPPLE — 2026-03-18

Eight new cicada species from the eucalypt forests of eastern Australia are described in the genus Yoyetta Moulds, 2012. Yoyetta argentea sp. nov. is found in the central highlands of Queensland; Y. burwelli sp. nov. is widespread in south-eastern Queensland and also occurs in far northern New South Wales; Y. clara sp. nov. occurs in the central highlands and in inland south-eastern Queensland; Y. eastwoodi sp. nov. is found in subcoastal central and south-eastern Queensland; Y. longirostra sp. nov. is restricted to south-eastern Queensland; Y. penetrans sp. nov. is known from coastal north-eastern New South Wales; Y. wrightae sp. nov. is distributed patchily through coastal and inland south-eastern Queensland; Y. zagona sp. nov. occurs in inland southern Queensland, inland New South Wales and north-western Victoria. The new species are broadly all allied to Y. tristrigata (Goding & Froggatt) and males of all species produce simple ticking or clicking songs and generally remain inconspicuous in the canopy. Within each species a description, as well as a section on distinguishing features, distribution, habitat and behaviour, and calling song structures are provided and illustrated where available. A revised key to species for the genus Yoyetta Moulds is also provided.

**First report of the genus Colastomion Baker, 1917 (Hymenoptera: Braconidae) from the Indian mainland and Andaman Islands with description of two new species**

ANKITA GUPTA — 2026-03-18

The relatively uncommon and small genus Colastomion Baker, 1917 is recorded for the first time from the Indian mainland as well as from the Andaman group of islands. Two new species, Colastomion indominutus Gupta, sp. nov. and Colastomion indosubequalis Gupta, sp. nov., are described and illustrated. Both the newly described species are compared with the other similar appearing Colastomion species known from the Oriental region.

**Recognition and revision of the Phelister panamensis group (Histeridae: Histerinae: Exosternini)**

MICHAEL S. CATERINO — 2026-03-18

Here we establish the Phelister panamensis species group, revising the eight included species (two of which are described as new). The nominate species is widely distributed in the Americas, from the US south to Argentina, and has probably expanded its distribution in association with domestic cattle, in whose dung it is often found. The group’s monophyly is strongly supported by unique hooks on the apex of the male 8^th sternite. Based on previous analyses, their affinities appear to be reasonably close to other ‘core’ Phelister, including the P. haemorrhous (which holds the type of the genus) and P. pusio groups. The P. panamensis group contains the following species: Phelister panamensis J.E. LeConte 1859, Phelister acoposternus Marseul 1853, Phelister amplistrius Schmidt 1893, Phelister brevistrius Marseul 1854, Phelister pumilus Erichson 1834, Phelister muscicapa Marseul 1870, Phelister apurimac sp. nov., and Phelister foveisternus sp. nov. We also designate lectotypes for Phelister omissus Schmidt (=P. panamensis), Phelister atrolucens Casey (=P. panamensis), Phelister amplistrius Schmidt, Phelister brevistrius Marseul, Phelister muscicapa Marseul, Phelister acoposternus Marseul, Phelister parvulus Erichson (=P. acoposternus), Phelister pumilus (Erichson), and Phelister confuseanus Marseul (=P. pumilus).

**Cryptic diversity within Nyctixalus (Anura: Rhacophoridae): a new species, a resurrection, and a redescription**

JENNIFER A. DEVER — 2026-03-18

The examination of molecular markers confirms hidden diversity and reveals a new species within the Nyctixalus pictus (Peters, 1871) complex. Three genetically distinct clades were recovered: one from the Thai-Malay Peninsula; one from Sumatra, Indonesia; and one from Sarawak, Borneo, East Malaysia. Voucher specimens from each region were compared, and significantly different mean values were found through morphological analyses. The populations also differ significantly in morphospace, as determined by PCA, DAPC, and MFA analyses. The Thai-Malay Peninsula individuals have a distinct, rounded and slightly elongated snout shape compared to the other two clades. Based on these combined data, these three clades are recognized as distinct species. The name N. anodon is reinstated for those from Sumatra, Indonesia. The type locality of Sarawak, East Malaysia for N. pictus restricts the distribution of the species to Borneo. The type specimen of N. pictus was lost (pers. communication, G. Doria), and no lectotype or syntypes were described; thus, a specimen from Sarawak, Borneo, in the collection of the Field Museum of Natural History, Chicago (FMNH), is designated here as the neotype of N. pictus.

**Report of colour polymorphism and range extension in two poorly known species of Indian Rhinophis (Squamata: Uropeltidae)**

GOVINDAPPA VENU — 2026-03-18

We report new scalation, colour-pattern, and distributional data on two poorly known species of Rhinophis from India’s Western Ghats region. We report the first phenotypic data for a population of R. sanguineus from Ambalavayal in Wayanad, Kerala, India, including a highly distinct colour polymorphism. This polymorphism is characterised by syntopically occurring conspecifics of R. sanguineus having either the typical pattern of a uniform dorsum or a previously unreported distinctly cross-banded form. We observed multiple cross-banded morphotypes as young and adults, as well as males and females. We also report on a new population of R. karinthandani from Bhagamandala, in the Kodagu Plateau, nearly 70 km north of the previously known range in the Wayanad Plateau. This finding opens the prospects for inferred presence of R. karinthandani in a few of the intervening massifs as well. Our new finding of R. karinthandani also provides an extended range in known numbers of ventral scales for the species. Taken together, these findings underscore the incomplete knowledge on Indian Rhinophis, both old and recently described species, regarding multiple facets of natural history.

**Revision of Zapatodes Orlandin, Piovesan & Carneiro, 2025 (Lepidoptera: Bombycoidea, Apatelodidae) with description of seven new species**

ELTON ORLANDIN — 2026-03-18

Zapatodes is a Neotropical genus of apatelodid moths (Lepidoptera, Bombycoidea) that was proposed to encompass seven species previously placed in Apatelodes Packard, 1864 and Olceclostera Butler, 1879. The dissection of specimens with similar habitus revealed consistent morphological differences in the genitalia, suggesting the presence of several undescribed species and prompting a taxonomic revision of the genus. In this study, we describe seven new species in this genus: Zapatodes amada Orlandin & Piovesan sp. nov., Zapatodes chorotega Orlandin & Simões sp. nov., Zapatodes kambeba Orlandin, Piovesan & Carneiro sp. nov., Zapatodes miranha Orlandin, Piovesan & Carneiro sp. nov., Zapatodes mundurukania Orlandin, Piovesan & Carneiro sp. nov., Zapatodes pimenteira Orlandin & Piovesan sp. nov., and Zapatodes sullivani Orlandin & Simões sp. nov. Additionally, to ensure unambiguous identification of names, a neotype was designated for Zapatodes ennomoides (Walker, 1865). This revision doubles the number of known species in the genus to 14, significantly expanding our knowledge of the diversity, distribution, and biology of Apatelodidae.

Studies on Neotropical crickets: A new slender and silent cricket genus (Orthoptera: Phalangopsidae) from the Magdalena Valley of Colombia

OSCAR J. CADENA-CASTAÑEDA — 2026-03-18

A new genus and a new species of phalangopsid crickets (Orthoptera: Phalangopsidae) are described from the inter-Andean valley of the Magdalena River, between the departments of Santander and Antioquia, Colombia. Silenszara magdalenensis gen. nov. et sp. nov. is distinguished by the absence of a stridulatory apparatus on the tegmina, the presence of metanotal glands, and conspicuously modified male genitalia, suggesting predominantly chemical communication and a complex sexual behavior. The current state of knowledge of luzarines in Colombia is discussed, emphasizing the need for further studies to document their taxonomic and behavioral diversity.

Three new species of Gastropoda from the Red Sea deep waters

ANTONIO BONFITTO — 2026-03-18

The discovery of three gastropod species (Mollusca) in biogenic sediments dredged from mesophotic and bathyal habitats off the coasts of Yemen and Sudan marks a noteworthy contribution to the inventory of marine biodiversity in the poorly studied Red Sea deep waters. These newly described species, Marginodostomia alibardii sp. nov., Miralda coronata sp. nov. and Iphitus marisrubri sp. nov., are currently known only from empty shells. The identification of adult Iphitus specimens in the Red Sea is particularly remarkable, given that members of this genus have previously been reported only from cold-water bathyal environments, in stark contrast to the present-day warm deep-water conditions of the Red Sea.

**New species of Chorizococcus McKenzie, 1960 and Spilococcus Ferris, 1950 (Hemiptera: Coccomorpha: Pseudococcidae) from India**

SUNIL JOSHI — 2026-03-18

Two new mealybug species (Hemiptera: Coccomorpha: Pseudococcidae) are described from India. The genus Spilococcus Ferris is recorded from India for the first time, with description and illustration of the new species, Spilococcus gullanae Joshi, Churi & Amembal, sp. nov., which is most similar to S. geraniae (Rau). Characters distinguishing S. gullanae from the other Spilococcus species recorded from the same host family in the same geographical area are discussed. A second new species is described and illustrated in the closely related genus, Chorizococcus McKenzie: C. watsonae Joshi, Pai & Deepthy, sp. nov. A key is provided to separate the adult females of Chorizococcus occurring in the Oriental region.

One new genus and species of Typhlocybini (Hemiptera: Cicadellidae: Typhlocybinae) from China

MENGYANG LI — 2026-03-18

A remarkable new genus of the leafhopper tribe Typhlocybini with significantly elongated style, Prodorsostyla gen. nov., is described based on a new species P. jinzishiensis sp. nov. found on Cinnamomum camphora from China. Habitus photos of the new species and its host plant as well as the photos of the male genitalia are provided.
