Among approximately 70 known <em>Lymanopoda</em> species, only five exhibit blue colour on the upperside of their wings, with no evidence of close relationships among them. The new species superficially resembles <em>L. samius</em> Westwood which occurs parapatrically at slightly lower elevations and belongs to a distantly related lineage within the genus. Remarkably, external morphology and male genitalia suggest a strong similarity of the new species to <em>L. hazelana </em>found in southern Ecuador and northernmost Peru—over 1300 km away. Molecular analysis using COI barcoding confirms that <em>L. hazelana</em> and a few other closely related species also found in southern Ecuador are the closest known relatives of <em>L. chysquyco </em><strong>sp. nov.</strong> This substantial geographic disjunction is unlikely to be a sampling artefact, as intermediate páramo regions of the Eastern and Central Colombian Cordillera and central Ecuador have been extensively surveyed. The origin of <em>L. chysquyco</em> <strong>sp. nov.</strong> in northern Colombia remains unclear, and two possible scenarios—long-distance dispersal or vicariance accompanied by large-scale extinction in intervening areas—are considered.</span></span></span></p> <p> </p> TOMASZ W.

Three new species from Trindade Island in the genera <em>Colomastix</em> Grube, 1861 (Colomastigidae Chevreux, 1899), <em>Pariphinotus</em> Kunkel, 1910 (Phliantidae Stebbing, 1899) and <em>Eusiroides</em> Stebbing, 1888 (Pontogeneiidae Stebbing, 1906) were recently described, bringing the number of amphipod species from TMV to thirteen.

Whereas the two species of <em>Mentophilus </em>are restricted to the western coast of the country, the 13 species of <em>Tesserodon </em>are much more widespread. The taxonomy and biogeography of these and other Australasian groups have been scrutinized over the past 50 years, but nomenclatural issues still persist. Here, we address them and conclude that: (1) the name “<em>Mentophilus hollandiae</em> Castelnau, 1840”, in use since 1974, is actually unavailable and the valid name for the species is <em>Mentophilus carinatus</em> (Reiche, 1841); (2) under Article 23.9.1 of the Code, precedence between the objective synonyms <em>Aulacium </em>Dejean, 1833, <em>nomen oblitum</em>, and <em>Mentophilus</em> Castelnau, 1840, <em>nomen protectum</em> (type species: <em>Aulacium carinatum</em> Reiche, 1841), is reverted, and the validity of <em>Mentophilus </em>is so preserved; (3) the grammatical gender of <em>Tesserodon </em>is masculine, not neuter as treated since the mid-20<sup>th</sup> century, and adjectival specific names in the nominative case must change their endings accordingly; (4) the name “<em>Anisodon </em>Hope, 1837” (<em>nec </em>Lartet, 1851, in Mammalia, <em>nec </em>Rosen, 1905, in Serpentes) is unavailable for failing to comply with Articles 11.5 and 11.6, and so does not threaten the validity of its synonym <em>Tesserodon</em>; (5) the correct original spelling is <em>Tessarodon</em>, a justified emendation established by the original author in an erratum, <em>Tesserodon </em>being formally an incorrect original spelling, thus invalid. To preserve stability, a Case is to be submitted to the International Commission on Zoological Nomenclature for the conservation of the incorrect spelling; in the meantime, prevailing usage is to be respected. A checklist is presented for all the species of <em>Mentophilus </em>and <em>Tesserodon </em>including information on synonymy, name-bearing types, type localities, and distribution.</span></span></span></p> <p> </p> MARIO CUPELLO PATRICE BOUCHARD MAXIMILLIAN HART MAXWELL V.L.

Despite a recently reported new collection from the type locality, knowledge about the species remains limited. During our recent field surveys in the state of Arunachal Pradesh, India, we collected new populations of <em>Gracixalus</em> frogs from Tale Valley Wildlife Sanctuary and Tiwarigaon. These were identified as belonging to <em>G. medogensis</em> based on external morphology and genetic evidence, constituting the first record of the species from India. Our matrilineal genealogy further recovers <em>G. medogensis</em> as having a deeply divergent phylogenetic position distinct from all other congeners. Additionally, we present a detailed morphological redescription of the species using multiple specimens. We also provide first insights into the male vocal repertoire in the species and compare it with call properties of other studied congeners. Furthermore, we report additional locality records in Namdapha National Park for <em>G. patkaiensis</em>, which was so far known as the sole representative of the genus in India. We also expand the knowledge on this species’ morphology, including colour variations, natural history, and habitat use. Our study additionally documents an interesting observation of green blood and turquoise bones in <em>G. patkaiensis</em>, making it the first report of this unique characteristic in a species of frog from India. Finally, our findings highlight the need to further investigate not only the diversity of <em>Gracixalus</em> in the northeastern region of India, but also the phylogenetic relationships among members, particularly of <em>G. medogensis</em>, and of <em>Gracixalus</em> sensu lato at large.</span></span></span></p> <p> </p> TAGE TAJO RADHAKRISHNA UPADHYAYA K.

However, analysis of their raw data revealed mostly double peaks at each nucleotide position, indicating ambiguity in the DNA sequence. These likely arose from a combination of factors, including irregular PCR efficiencies and slight primer mismatches. Zhang <em>et al.</em> (2008) likely misinterpreted these double peaks as evidence of distinct subspecies. This resulted in an inflated number (56) of variation sites. Their interpretation was further confounded by potential issues with their primers, designed from a sequence of <em>F. peregrinus</em> with a one-nucleotide difference. To address these limitations, we sequenced the full mtDNA control region (1,266bp) of 38 Common Kestrel samples using newly designed primers. This analysis yielded clean, single-peak profiles for each sequence, confirming that all samples belonged to <em>F. t. interstinctus</em>. We therefore propose reclassifying these populations as a single subspecies, <em>F. t. interstinctus</em>. Erroneous barcode sequences can distort subspecific identification and population structure, leading to inaccurate data and misleading phylogenetic inferences. Our study underscores the critical need for robust methods to minimize barcode sequencing errors. This would not only ensure accurate phylogenetic inferences for Common Kestrels but also support reliable population genetic studies across diverse taxa. </span></span></span></p> <p> </p> JIN-WOO SEONG JONG-GIL PARK DONG-HA NAM Copyright (c) 2025 2025-07-07 2025-07-07 5659 4 536 546 10.11646/zootaxa.5659.4.4 <strong>An off-key anuran singer: an unusual male release call in invasive cane toads in Hawaiʻi</strong> https://www.mapress.com/zt/article/view/zootaxa.5659.4.8 FRANK ALVIN GOZON BAGUIO THAYNARA MENDES MACHADO BRENDEN STEPHEN HOLLAND LUÍS FELIPE TOLEDO Copyright (c) 2025 2025-07-07 2025-07-07 5659 4 589 592 10.11646/zootaxa.5659.4.8 <strong>First record of the genus <em>Piratula</em> Roewer, 1960 from India, with the description of a new species (Araneae: Lycosidae: Zoicinae)</strong> https://www.mapress.com/zt/article/view/zootaxa.5659.4.9 PUTHOOR PATTAMMAL SUDHIN PRADEEP M.
