The Filistatidae in the Caribbean region, with a description of the new genus Antilloides, revision of the genus Filistatoides F. O. P.-Cambridge and notes on Kukulcania Lehtinen (Arachnida, Araneae)

Abstract

A synopsis of Caribbean filistatid diversity is recorded herein. A new genus, Antilloides, is proposed for five new species exclusively found in the Antilles: A. abeli n. sp., A. cubitas n. sp., and A. mesoliticus n. sp. from Cuba; A. haitises n. sp. from the Dominican Republic; and A. zozo n. sp. from the U. S. Virgin Islands and Puerto Rico. The genus Filistatoides is revised and includes four species: the type species F. insignis F.O.P. Cambridge, which occurs only in Guatemala; the female is described here for the first time; F. polita Franganillo sp. reval., comb. nov., which occurs only in Cuba; F. xichu n. sp. described from Mexico; and F. milloti (Zapfe) which does not appear to belong to the genus based on morphological structures. Additionally, Kukulcania isolinae Alayón is synonymized with Kukulcania hibernalis (Hentz), and new records of its distribution are included for the Greater and Lesser Antilles.

Phylogeny and biogeography of the ancient spider family Filistatidae (Araneae) is consistent both with long‐distance dispersal and vicariance following continental drift

“…This species remained the only South American member of Filistatoides (a genus restricted only to North America and the Antilles). The phylogenetic results indicate unambiguously it belongs in Pikelinia , as previously suggested (e.g., Brescovit et al., 2016b). The species has not had its genitalia illustrated in the literature and will be properly redescribed and illustrated in an upcoming revision of the genus.…”

“…In the ensuing decades, several regional taxonomic reviews were carried out, and in many of them new generic names were proposed: Wang (1987; China, Tricalamus ), Zonstein (1990; former Soviet Union, Microfilistata ), Gray (1994; Australia, Wandella and Yardiella ), Ramírez and Grismado (1997; Argentina, Lihuelistata and Misionella ) and Brescovit et al. (2016b; Caribbean, Antilloides ). Finally, during the beginning of the 21st century, researchers working on Pholcidae discovered two genera of Filistatidae had been erroneously described in that family and proposed their transfer to the correct family ( Pholcoides Roewer, transferred by Huber, 2009; Mystes Bristowe, transferred by Huber et al., 2014).…”

Contribución al conocimiento de las arañas (Arachnida: Araneae) en Sonora, Noroeste de México

“…La determinación a nivel genérico o específico se realizó usando un microscopio estereoscópico ZEIZZ Stemi DV4 y apoyándose en los trabajos de Pickard-Cambridge, F. O. (1902) para Deinopidae, Brescovit et al (2016) Gertsch (1958) para Plectreuridae, Platnick & Penney (2004) para Prodidomidae y Platnick y Shadab (1974) para Trachelidae. Los especímenes juveniles se determinaron a nivel genérico o hasta especie previa corroboración de las características somáticas con los adultos.…”

“…Los especímenes aquí examinados corresponden a una nueva especie en proceso de descripción. (Brescovit et al, 2016). Por otra parte, las hembras de Filistatoides se diferencian de otros géneros por presentar la base de cada espermateca larga, que se estrecha anteriormente, formando un receptáculo distal redondo (Brescovit et al, 2016).…”

Revision of recluse spiders (Araneae: Sicariidae: Loxosceles) preserved in Dominican amber and a total-evidence phylogeny of Scytodoidea reveal the first fossil Drymusidae

“…This is certainly more probable for specimens described in Holocene copal or Defaunation resin from the Dominican Republic (e.g., Wunderlich 1986) since these resins can have an age of only 60 years BP (conventional radiocarbon age) (Solórzano- Kraemer et al 2020). For some families, this hypothesis has been confirmed, such as for Filistatidae, initially known from Hispaniola by fossil specimens (Penney 2005) but later showed to include extant Dominican taxa endemic to the island (Brescovit et al 2016). Some families with extant Hispaniolan taxa have hitherto not been recorded in amber, such as Drymusidae, which includes Drymusa simoni Bryant, 1948 from Haiti (see WSC 2022) and unidentified species from the Dominican Republic (Solanlly Carrero, pers.…”
