Bioacoustics of Kerivoula papillosa

Remarks: K . malayana was described based on a specimen collected at the Selangor-Pahang border in Peninsular Malaysia [ 8 ]. Two forms of K . papillosa which are different in forearm length and acoustic characters were reported from Krau Wildlife Reserve, Peninsular Malaysia [ 177 ]. However, Douangboubpha et al. [ 170 ] reported five morphological forms within three distinct clusters based on COI mtDNA ( K . papillosa A, Band C) in Thailand . K . papillosa A corresponds with K . p . malayana based on the size a larger skull and higher braincase and is 6.97% divergent from K . papillosa Bwhich comprises two morphological forms. The smaller K . papillosa B (forearm length: 42.1–42.3 mm and length of skull: 17.0–17.1 mm) and the larger K . papillosa B (forearm: 39.4–40.2 mm and length of skull: 16.6–17.0 mm) are only 1.99% divergent and may or may not represent a further undescribed species. K . papillosa Cis only 0.55% divergent from K . lenis collected in Peninsular Malaysia with morphological variation, and is 13.06% and 14.86% divergent from K . papillosa Aand Brespectively (see Fig 9 in [ 170 ]). Our NJ analysis ( Fig 6 ) revealed three clusters of DNA barcodes recorded as K . papillosa corresponding to three BINs, BOLD:AAC9527, BOLD:AAC9528 and BOLD:AAC9529. It is likely that BIN, BOLD:AAC9529 (as K . papillosa Small in [ 169 ] and as K . papillosa A [ 170 ]) with DNA barcodes recorded as K . papillosa and K . cf. papillosa represent K . p . malayana based on type locality. We conservatively retained K . papillosa in our checklist and propose further research be conducted to address the suggestion that “ malayana ” to recognised as a distinct species.
