ABSTRACT:
Among populations of Oliarus polyphemus FENNAH, a troglobitic species found in numerous lava tubes on Hawaii Island, a high degree of behavioral differentiation concerning the intraspecific communication signals has been observed (HOCH & HOWARTH 1993). HOCH AND HOWARTH (1993) hypothesized that some of these populations were likely to represent species in statu nascendi or even reproductively isolated species. In order to qualitatively and quantitatively survey the discontinuities between the populations variance and discriminance analyses were carried out based on morphological and ethological characters of individuals from 10 caves. According to the statistic species criterion as proposed by R. REMANE (1968), nine populations must be regarded at least as subspecies, while one population is likely to have acquired species status.
