title: First record of the family Calliopiidae (Crustacea, Malacostraca, Amphipoda) from Korean waters, with description of new species Calliopius ulleungensis sp. nov.

description: This dataset contains the digitized treatments in Plazi based on the original journal article Kim, Kyung-Won, Kim, Young-Hyo (2024): First record of the family Calliopiidae (Crustacea, Malacostraca, Amphipoda) from Korean waters, with description of new species Calliopius ulleungensis sp. nov. ZooKeys 1221: 297-307, DOI: 10.3897/zookeys.1221.139066AbstractA new species of the family Calliopiidae was collected from the East Sea of Korea. Calliopius ulleungensis sp. nov. is similar to C. columbianus Bousfield & Hendrycks, 1997 in having numerous calceoli on the posteromedial margins of antennae and a weakly carinate body. However, the new species can be distinguished from C. columbianus by the shorter process on peduncular article 3 of antenna 1, subrectangular eyes, and fewer articles in the antenna flagellum. This species, along with C. ezoensis Shimoji et al. 2020, occurs in the Western Pacific. The females of the two species are morphologically very similar, but the males of C. ezoensis are easily distinguishable, as the gnathopod 1 is larger than gnathopod 2. The new species is fully illustrated and extensively compared with related species. In this paper, both Calliopius and Calliopiidae are reported from Korea for the first time. A key to species of Calliopius is also provided.

This species is distinguished from all other congeneric species in China due to having a unique body coloration, comprising 20-25 transverse black bars on the dorsum and upper part of the flank. Other characteristics, though not exclusive to this species, include an indistinct blackish mid-dorsal stripe from the nape to the caudal-fin base, a lower jaw fully covered by the lower lip; 17-20 black vertical bars on the lower part of flank, a short suborbital spine with a shorter processus latero-caudalis that is less than one-fifth the length of the processus medio-caudalis, and seven branched dorsal-fin rays. The validity of the new species is corroborated by its monophyly, as evidenced by phylogenetic analysis based on the mitochondrial cytochrome b gene.

Excipulariopsis has non-cupulated superficial conidiomata arising directly from stroma surrounded by thick walled dark brown subulate setae. The conidia are dark brown, broadly fusoid, having thick septa and truncate base. Phylogenetic analyses using ITS, LSU, TEF1α and RPB2 sequences positioned Excipulariopsis allied to Speiropsis in the family Wiesneriomycetaceae, as a sister family to Tubeufiaceae within Tubeufiales. This study resolved a long-standing ambiguity about the phylogenetic status of this unique sporodochial setose hyphomycetes from India.

title: Two new Periconia species (Pleosporales, Ascomycota) in China

description: This dataset contains the digitized treatments in Plazi based on the original journal article Tian, Xing-Guo, Han, Jia-Jun, Hongsanan, Sinang, Lu, Yong-Zhong, Karunarathna, Samantha C., Bao, Dan-Feng, Tibpromma, Saowaluck (2025): Two new Periconia species (Pleosporales, Ascomycota) in China. MycoKeys 125: 307-324, DOI: 10.3897/mycokeys.125.173913AbstractDuring an investigation of fungal diversity in Guangxi and Yunnan provinces, two interesting hyphomycetes were collected and isolated. Based on morphology, these hyphomycetes were similar to Periconia - like taxa. To confirm their classification, morphological characterization and multigene phylogenetic inference (using LSU, ITS, SSU, and tef 1 - α) were employed. Based on phylogenetic analyses, our two collections clustered within Periconia (Periconiaceae) as distinct two taxa, and morphological analyses also confirmed that they are new species of Periconia. Periconia guangxiense sp. nov. formed a well-supported monophyletic lineage (92 % ML / 1.00 PP) sister to P. variicolor, but morphologically, it is distinguishable by its branched, micronematous to semi-macronematous conidiophores. While Periconia xishuangbannaensis sp. nov. formed a distinct lineage closely related to P. guangxiense; it is distinguished by its macronematous conidiophores and dark brown conidia. This study highlights the role of unique habitats in driving fungal diversity and contributes to the taxonomic refinement of the Periconia genus.

title: P=NP is True _ the python script

description:  

This work documents the proof that the complexity class NP is equivalent to the class P. Using the Pezzotti Method, i demonstrate that decision and search problems deemed “exponential” can be solved in polynomial time O(n^k). The key to the solution lies in Rank Saturation: by identifying the constraint order and operating in finite fields \mathbb{F}_p, the system instantly detects the fertility (solution) or sterility (impossibility) of the variety of constraints.

Acta Entomologica Musei Nationalis Pragae 55 (2): 513-538, DOI: 10.5281/zenodo.5303773Abstract. Two new species of the large pantropical jumping plant-louse genus Pseudophacopteron Enderlein, 1921 (Hemiptera: Psylloidea: Phacopteronidae) are described from dry woodland habitats in the Midwest, Southeast and South of Brazil. Pseudophacopteron aspidospermi sp. nov. is associated with Aspidosperma australe, P. longicaudatum sp. nov. has been found on Aspidosperma macrocarpon and A. tomentosum (Apocynaceae). Both species induce intralaminar lenticular galls on the leaves of their host trees which have been the subject of several structural, histochemical and ecological publications. Adult males and females, fifth instar immatures and galls are illustrated including diagnostic morphological details, and compared with other Neotropical and Old World species of Pseudophacopteron and Phacopteronidae. The distribution of Pseudophacopteron in the Neotropical Region is briefly discussed.
