Pukapuka: fieldspecimen+photo, 3/2004, K.Salisbury, tentative ID as Ariomma brevimanus by Rudie Kuiter 12/2004, tentatively confirmed Peter Last 1/2005, "Looks like Ariomma brevimanus based on ca 50 LL scales or more (although difficult to count from photo). Ariomma evermanni is the other possibility (fewer than 45 LL scales)"; and M.Francis counted 52 LL scales.
