  First Description of the Male of Zelotes sindi Caporiacco, 1934 (Araneae: Gnaphosidae) With Its Phylogenetic Placement Abstract The male of Zelotes sindi Caporiacco, 1934, previously unknown to science, is documented for the first time based on specimens collected from the Kashmir Himalayas, India. Detailed description and illustrations of the habitus and the palp are provided. Genomic DNA was extracted from a spider leg, and the barcode sequence is available in GenBank under the accession number PQ763483 and the Barcode Index Number BOLD: AGP6100 in Barcode of Life Data Systems. Phylogenetic analysis supported its genetic distinctiveness and was in congruence with current morphological identification. Zehbi, N., Yousuf, M., & Ganai, B.A. (2026).

Resurrection of the erigonine spider Ceratinopsis tybeensis (Araneae: Linyphiidae) with the first description of the male

Abstract 

The erigonine linyphiid spider Ceratinopsis tybeensis Chamberlin & Ivie, 1944 was described from a single female collected in Savannah Beach, Georgia, USA. Subsequently, it was declared a junior synonym of Masonetta floridana (Ivie & Barrows, 1935) by Ivie (1967). However, recent multiple collections of females of M. floridana with specimens of an undescribed erigonine male has thrown this synonymy into question. Recent new research using morphological and molecular evidence supports our hypotheses that the synonymy proposed by Ivie is erroneous and the new male is the previously undescribed male of C. tybeensis. Herein, we resurrect C. tybeensis, provide the first description of the male, redescribe the female, and document increases to the known ranges of C. tybeensis and M. floridana.
