title: New and previously described Acleotrema species (Monogenea, Diplectanidae) parasitizing sea chubs (Centrarchiformes: Kyphosidae) in the Southeastern Pacific Ocean

description: This dataset contains the digitized treatments in Plazi based on the original journal article Santillan, Angel L., Cruces, Celso L., Mondragón-Martínez, Aarón, Rojas, Rosa Martínez-, Chero, Jhon D. (2025): New and previously described Acleotrema species (Monogenea, Diplectanidae) parasitizing sea chubs (Centrarchiformes: Kyphosidae) in the Southeastern Pacific Ocean. Zootaxa 5570 (3): 533-548, DOI: 10.11646/zootaxa.5570.3.5, URL: https://doi.org/10.11646/zootaxa.5570.3.5AbstractDuring a study on the diversity of monogeneans infecting kyphosid fishes off the coast of Puerto Santa Rosa, Lambayeque region, northern Peru, specimens of the Cortez sea chub Kyphosus elegans (Peters) and the brassy chub K. vaigiensis (Quoy & Gaimard) were examined. Five diplectanids, including a new species, were identified: Acleotrema alejandroi sp. nov. from K. vaigiensis; A. diplobulbus (Yamaguti, 1968) from K. vaigiensis; A. nenue (Yamaguti, 1968) Dominques & Boeger, 2007 from both K. vaigiensis and K. elegans; A. oliveri (León-Régagnon, Pérez-Ponce de León & Garcia Prieto, 1997) from K. elegans and K. vaigiensis; A. spiculare (Yamaguti, 1968) from K. vaigiensis. Acleotrema alejandroi sp. nov. is easily differentiated from all congeneric species by its male copulatory organ (MCO), which is J-shaped with a spatulate distal end. The middle portion of MCO is surrounded by a sclerotized sac; and the distal portion of the sac bears an elongated, sclerotized U-shaped process. Acleotrema oliveri is redescribed based on examination of the type specimen (holotype and paratypes) and newly collected specimens. In addition, new morphometric data and whole-mount drawing of A. nenue, A. spiculare and A. diplobulbus are provided. Acleotrema nenuoides (Rakotofiringa, Oliver & Lambert, 1987) is considered a junior synonym of A. nenue. The present finding brings to 13, the number of known species of Acleotrema Johnston & Tiegs, 1922, and represents the first diplectanid species infecting kyphosid fishes from Peru. Furthermore, this study represents the first record of A. spiculare and A. diplobulbus after more than 50 years.

Four species are recognized, of which one species closely related to Polyrhachis constructor Smith, 1857 is described and illustrated as new to science based on the worker caste under the name Polyrhachis longipilosa sp. nov. The queens of P. flavicornis Smith, 1857 and P. constructor, and the males of P. flavicornis and P. varicolor Viehmeyer, 1916 are described. The new species is distributed in western Thailand in the area north of the Isthmus of Kra, while P. constructor is distributed in Malaysia (West Malaysia and Sabah), Indonesia, Singapore, southern and western Thailand. Polyrhachis piliventris Smith, 1857 and Polyrhachis elii Emery, 1900 are synonymized with P. constructor. A key to the Thai species of the Polyrhachis flavicornis species group is given.

title: Understanding the color variability and resolving taxonomic confusion in the sea cucumber Isostichopus badionotus (Echinodermata, Holothuroidea): a revision of the genus Isostichopus

description: This dataset contains the digitized treatments in Plazi based on the original journal article Borrero-Pérez, Giomar H., Solís-Marín, Francisco A., Lessios, Harilaos (2024): Understanding the color variability and resolving taxonomic confusion in the sea cucumber Isostichopus badionotus (Echinodermata, Holothuroidea): a revision of the genus Isostichopus. European Journal of Taxonomy 949 (1): 1-96, DOI: 10.5852/ejt.2024.949.2641, URL: https://europeanjournaloftaxonomy.eu/index.php/ejt/article/download/2641/12173Abstract. Isostichopus badionotus (Selenka, 1867) is distributed in the Atlantic Ocean. It has been recognized as a species with highly variable intraspecific coloration. To clarify taxonomic confusion and show the characters for correct identification of this valuable species, mitochondrial DNA (16S and COI), color patterns, external and internal morphology, ossicles, and habitat were examined in specimens from museum collections and from original sampling. As part of the revision, I. fuscus (Ludwig, 1875) from the Eastern Pacific Ocean and I. macroparentheses (Clark, 1922) from the Caribbean Sea, the only other two species currently recognized in the genus Isostichopus, were included. It was concluded that I. fuscus and I. macroparentheses are distinct and valid species, and that I. badionotus consists of two species: I. badionotus and I. maculatus (Greeff, 1882), previously synonymized as I. baqdionotus by Clark (1922). Isostichopus maculatus includes two subspecies, the nominal I. maculatus maculatus (Greeff, 1882) and I. maculatus phoenius (Clark, 1922), described as Stichopus badionotus var. phoenius Clark, 1922. Isostichopus maculatus maculatus, distributed in the East Atlantic, is very similar to I. maculatus phoenius, but differs in DNA characters, color pattern, and the size and shape of the tables in the dorsal papillae. Isostichopus maculatus phoenius, widely distributed in the Caribbean Sea and the Gulf of Mexico, is sympatric with I. badionotus, has similar ossicles but is clearly distinguished by its DNA sequences, color patterns, and habitat preferences. For the first time, ossicles from internal organs are described for Isostichopus, enhancing original species descriptions. Distribution maps, habitat, biology, conservation status, and a taxonomic key for distinguishing these species to aid their fishery management and aquaculture are presented.

title: Revisiting and rediscovering the tarantulas (Araneae, Theraphosidae) of Culapnitan (Libmanan) Caves in the Philippines: troglomorphism, taxonomy, phylogeny and ecological niche

description: This dataset contains the digitized treatments in Plazi based on the original journal article Acuña, Darrell C., Ragasa, Lorenz Rhuel P., Santiago-Bautista, Myla R., von Wirth, Volker, Guevarra Jr, Leonardo A. (2025): Revisiting and rediscovering the tarantulas (Araneae, Theraphosidae) of Culapnitan (Libmanan) Caves in the Philippines: troglomorphism, taxonomy, phylogeny and ecological niche. Subterranean Biology 52: 143-186, DOI: 10.3897/subtbiol.52.142334AbstractIn 1892, French naturalist Eugène Simon described samples of cave-dwelling tarantula species collected from Culapnitan Caves in the Philippines, a cave system that is now part of the present-time Libmanan Caves Natural Park (LCNP). One of these is the new monotypic tarantula genus and species of that time, Orphnaecus pellitus Simon, 1892. Based on Simon’s notes and quick observation of the eyes of the syntypes, this species is highly suspected to be troglobitic. In the present study, we rediscovered O. pellitus from its reported site and investigated its troglobitic characteristics. Morphological analysis of O. pellitus shows troglomorphic characteristics which include reduced eye size, attenuated limbs, shortened tactile setae, and diminishing pigmentation. Tolerance to hypoxia and heightened sensitivity to ground movements are the other subterranean adaptations that were observed. Phylogenetic analysis revealed a cladistic relationship among tarantula morphologically identified from the genus Orphnaecus. Our findings provide evidence that O. pellitus is a true troglobitic tarantula reported worldwide, and currently the only one known from Asia. We also report two new species of Orphnaecus, Orphnaecus libmanan sp. nov. and the dwarf Orphnaecus tangcongvaca sp. nov., collected from the forest grounds of the LCNP. The ecological niche differentiation of theraphosid species in the LCNP is also provided. Our findings are supported by morphology, molecular phylogeny, and ecology.
