Histograms showing length ratios of some troglomorphic features among Namalycastis (boldface) and Namanereis (lightface) species. A Ratios between length of tentacular cirri (Lpt) and wide of prostomium (Wp) B Difference (Dd-v) between ratios of dorsalmost (Dm) and ventralmost (Vm) falcigers at chaetiger 10. Sorted from highest to lowest ratios; asterisks highlight stygobiont Namanereis.
