摘要

Two species of Gelidium, Gelidium usmanghanii and Gelidium pusillum var. pakistanicum are reported only from Pakistan, but their taxonomic status, phylogenetic relationships, and distributions have not been assessed with molecular data. Analysis of rbcL sequences revealed that G. usmanghanii was a distinct species with a distribution extending at least to the coast of Oman. This analysis also resolved G. pusillum var. pakistanicum within a Gelidium millariana species complex that was distantly related to G. pusillum. Further analyses of rbcL and COI-5P sequences showed that G. pusillum var. pakistanicum was a distinct species in this complex, and based on these molecular, and previous morphological results, this variety is elevated to the rank of species as Gelidium pakistanicum stat. nov.

Debar: A sequence-by-sequence denoiser for COI-5P DNA barcode data

Cameron M. Nugent, Tyler A. Elliott, Sujeevan Ratnasingham, Paul D. N. Hebert, Sarah J. Adamowicz

Summary: DNA barcoding and metabarcoding are widely used for species discovery and biodiversity assessments, but high error rates can inflate estimates. The debar package utilizes a hidden Markov model to denoise COI sequences, reducing indel errors and being sensitive to true COI variation in the animal kingdom. This results in more accurate sequences and aids in characterizing species diversity.

Taxonomic revision of the Peyssonneliales (Rhodophyta): Circumscribing the authentic Peyssonnelia clade and proposing four new genera and seven new species

Edilene Maria dos Santos Pestana, Jose Marcos de Castro Nunes, Valeria Cassano, Goia de Mattos Lyra

Summary: The Peyssonneliaceae is the only family in the order Peyssonneliales, encompassing widespread red encrusting algae. Through molecular phylogenies and morphological analyses, a revised taxonomic scheme for the Peyssonneliales has been proposed, uncovering underestimated diversity in Brazilian red algae.

Two new species of Aphis (Toxoptera) Koch (Hemiptera, Aphididae) from China

Zhentao Cheng, Xiaolei Huang

Summary: Two new species of aphids were described, Aphis (Toxoptera) fafuensis and Aphis (Toxoptera) sennae, which feed on Adinandra millettii and Senna bicapsularis, respectively, in China. Morphological and molecular data supported the taxonomic classification of these new species within the subgenus Aphis (Toxoptera). A key for identifying apterous viviparous females of this subgenus was provided.
