Further Brazilian “pachylines” absorbed into the DRMN clade: The genus Gyndoides Mello-Leitão, 1927 revisited (Opiliones, Gonyleptidae)

The ongoing depletion of the diversity of Pachylinae, the largest subfamily within Gonyleptidae, is progressing. The unranked clade DRMN continues to expand, now incorporating two additional genera – Gyndoides Mello-Leitão, 1927, and Sertaneja Saraiva, Hara & DaSilva, 2021 – previously classifie...

Description
Summary:The ongoing depletion of the diversity of Pachylinae, the largest subfamily within Gonyleptidae, is progressing. The unranked clade DRMN continues to expand, now incorporating two additional genera – Gyndoides Mello-Leitão, 1927, and Sertaneja Saraiva, Hara & DaSilva, 2021 – previously classified under Pachylinae. Through a cladistic analysis, with an expansion of the morphological dataset used in previous works, our research reveals that both Gyndoides and Sertaneja are separately placed within DRMN. As DRMN is not a formal Linnean taxon, both genera are herein called Gonyleptidae incertae sedis to avoid the establishment of new monogeneric subfamilies. A new species of Gyndoides is described from the state of Paraná, marking the first record for the genus from this state. The other two species, from Santa Catarina state, are herein redescribed, and an emended diagnosis is provided for the genus.
