title: Morphological ontogeny of Phauloppia nemoralis (Acari, Oribatida, Oribatulidae) with comments on Phauloppia Berlese

description: This dataset contains the digitized treatments in Plazi based on the original journal article Seniczak, Anna, Seniczak, Stanisław (2022): Morphological ontogeny of Phauloppia nemoralis (Acari, Oribatida, Oribatulidae) with comments on Phauloppia Berlese. Zootaxa 5187 (1): 69-94, DOI: 10.11646/zootaxa.5187.1.7AbstractThe morphological ontogeny of Phauloppia nemoralis (Berlese, 1916) is described and illustrated. The adult of this species is most similar to Ph. incomperta (Pérez-Íñigo et Peña, 1996), but differs from it mainly by the shape of bothridial seta, porose areas Aa and A1, and location of porose area A1 and seta ad 3. In the juveniles of Ph. nemoralis, the prodorsal setae ro, le and in are of medium size or long, ex is short, and the bothridial seta is of medium size and clavate, with barbed head. The larva has 12 pairs of gastronotal setae, the nymphs have 14 pairs; all are of medium size and barbed. In this species, the basal excentrosclerites occur, at setae c 2, h 1 and l -series in the larva, and c 2, p 1 and l - and h -series in the nymphs. In all nymphs, solenidion ω 2 on tarsus I is longer and thinner than ω 1, and seta ft'' is relatively long and located posterior to solenidion ω 2.

description: This dataset contains the digitized treatments in Plazi based on the original journal article Duckett, Catherine N. (2003): A new species of flea beetle, genus Pedilia Clark (Coleoptera: Chrysomelidae: Galerucinae), from Osa Pennisula, Costa Rica. Zootaxa 158: 1-8, DOI: 10.11646/zootaxa.158.1.1, URL: https://biotaxa.org/Zootaxa/article/view/zootaxa.158.1.1AbstractA new species of Pedilia Clark, P.sirena, from Costa Rica is described and illustrated. This species is monophagous on Passiflora pittieri HBK, and known only from the Sirena area of Parque National Corcovado, Costa Rica, for which it is named. Previous scientific reports mentioning this species are discussed, specifically those treating its ecological interaction with Heliconius hewistoni Staudinger, (Lepidoptera: Nymphalidae). This species is also notable for the two distinctly textured areas of its mandibular mola.

title: Distribution and geographic variation pf Comaroma simonii Bertkau, 1889 (Arachnidae, Araneae, Anapidae)

description: This dataset contains the digitized treatments in Plazi based on the original journal article Kropf, C. (1998): Distribution and geographic variation pf Comaroma simonii Bertkau, 1889 (Arachnidae, Araneae, Anapidae). Biosystematics and Ecology Series 14: 315-331, URL: http://antbase.org/ants/publications/Kropf1998/Kropf1998.pdfAbstract: The Central European anapid, Comaroma simonii Bertkau, shows a disjunct distribution area. The main area is situated in Austria and Slovenia. A second, northwestern population occurs in Belgium, the Netherlands, western Germany and western Switzerland. In addition, isolated findings are known from Bohemia, Slovakia, northern and central Italy and Montenegro. The few north-western specimens known up till now, differ morphologically from those of the main area by the number of eyes, the structure of female copulatory organs and by their female biased sex ratio. Specimens from Montenegro differ from all other populations in body colouration and in the number of chemosensitive hairs on tibia IV. The data indicate that specimens from the north-western area represent a separate, morphologically differentiated population as compared to specimens from the main area. However, the morphological data reveal no species differentiation between populations of C. simonii at present. Because of poor faunistic knowledge about the Balkan peninsula, it cannot be decided if this is also true for specimens from Montenegro.

This species is morphologically and phylogenetically (ITS and nLSU) close to Neomensularia crocitincta, distributed in Central America, Cuba and Jamaica, but can be distinguished by its larger basidiomata, a duplex context featuring a distinct black line, and golden yellow basidiospores. Additionally, an updated identification key for Neomensularia species worldwide is provided.

(2024): A new species of Rhyacophila Pictet, 1834 (Trichoptera, Rhyacophilidae) from Corsica with the genomic characterization of the holotype. ZooKeys 1218: 295-314, DOI: 10.3897/zookeys.1218.132275AbstractWe describe a new species in the Rhyacophila tristis group, Rhyacophila lignumvallis Graf & Rázuri-Gonzales, sp. nov., from the island of Corsica (France) based on a single male specimen. In addition to the morphological differences between the new species and the most similar species in the group, we also provide a phylogenetic tree based on the mitochondrial cytochrome c oxidase subunit I (mtCOI), including sequences from 16 out of the 28 currently recognized species in the group. These data, together with conspecific larval sequences, support the status of the new species and shed light on an additional potential new species near Rhyacophila pubescens. Using a low-cost next-generation sequencing approach, we generated the mito- and draft nuclear genome assembly of the holotype of R. lignumvallis sp. nov. as well as that of R. tsurakiana. This genetic data represents an important additional characterization to the description of morphological features and is valuable for future investigations, such as population or phylogenomic studies.

description: This dataset contains the digitized treatments in Plazi based on the original journal article Sato, Mao, Ito, Shohei, Fujiwara, Yoshihiro, Koeda, Keita (2025): First northwestern Pacific records of the deep-sea cardinalfish Epigonus glossodontus (Teleostei, Epigonidae) from the Daito Islands, Japan. ZooKeys 1231: 1-10, DOI: 10.3897/zookeys.1231.136445AbstractThe deep-sea cardinalfish Epigonus glossodontus Gon, 1985, previously known only from the Hawaiian Islands, was observed using remotely operated vehicles (ROVs) on steep seafloors surrounding Kitadaito and Minamidaito islands, both being oceanic islands belonging to the Daito Islands, Japan in the northwestern Pacific. A total of 44 hours of ROV observations found sparse populations, each of several individuals, around or within small caves, fissures, and recesses, specifically at depths of 340–588 m within the surveyed depth of 284–1009 m. Seven individuals (36.0– 114.8 mm standard length) were successfully collected during the ROV observations around the Daito Islands. A subsequent record of the species (97.5 mm standard length) from the Kyushu-Palau Ridge indicated that the species is widely distributed. A glossy bluish-green body color with black-margined scales was revealed by the field observations, the glossy color fading immediately after death.

The new species is recognized by the following combination of characters: abdomen naked; two or three preanal plates; a bony plate before each branchial opening; seven lateral plates between the pectoral and pelvic fins; maxillary barbel short and attached to the oral disk by a fleshy fold; head dorsal surface and anterior portion of the body light or dark yellow with numerous, round black spots; posterior region of the body light or dark yellow with five black transverse bands, dorsal central area of the two anterior bands diffused. The discovery of this new species extends the distribution of the genus northwest to include the Orinoco River basin on the northern slope of the Guyana shield.Harttia merevari, uma espécie nova de bagre loricarideo é descrita com base em oito exemplares capturados no alto rio Caura, bacia do rio Orinoco, Venezuela. A espécie nova se distingue pela seguinte combinação de caracteres: abdome nu; duas ou três placas preanais; presença de uma placa óssea anterior a cada abertura branquial; sete placas laterais entre as nadadeiras peitorais e pélvicas; barbilhão maxilar curto e unido ao disco oral por uma dobra carnosa; superfície dorsal da cabeça e região anterior do corpo amarelo escuro ou marrom claro com numerosos pontos negros arredondados, região dorsal e posterior do corpo amarelo escuro ou marrom claro com cinco bandas transversais negras, as duas bandas anteriores com a parte dorsocentral difusa. A descoberta desta espécie nova estende a distribuição do gênero ao noroeste incluindo a bacia do rio Orinoco na vertente norte do Escudo das Guianas.Key Words: Taxonomy, Harttiini, Caura River, Orinoco River basin, Guyana shield, Biogeography.
