Ischnothyreus peltifer ( Simon, 1892) ( Figs. 2 C–D )

Ischnaspis peltifer Simon, 1892: 562 (♀).

Ischnothyreus peltifer : Platnick et al., 2012: 7 , figs. 1–99 (♂ ♀).

For full synonymy list, see WSC (2023).

Diagnosis and description. See Platnick et al. (2012).

Material examined. 1 ♀ ( ASC L17 2 PFJ), Ascension Island (-7.95, -14.35), Silicic pyroclastic deposits, pitfall trap baited with jam, 28/01/2022, coll. A. Sharp.

Distribution. Pantropical (WSC 2023), inclusive of Ascension Island (new record, introduced).

Remarks. The epigyne of the examined specimen matches well with published illustrations (Platnick e t al. 2012) and we therefore determine the Ascension specimen as I. peltifer . This species is also recorded for Saint Helena (see Benoit, 1977) but Platnick et al. (2012) express doubts about the identity of the Saint Helenian material. It is outside the scope of the current work to investigate this matter but the senior author is investigating it in the near future on another grant (Sherwood et al. in prep.).
