Micropholcomma longissimum is remarkable for the exaggerated length of the male embolus (see Forster and Platnick 1984 , fig. 369) and the concomitantly extreme development of the female insemination ducts, the latter of which are very tightly coiled around the fertilisation ducts (Fig. 15E). There are, however, a number of undescribed species of Micropholcomma in both eastern and south-western Australia that share a very similar, ‘super-coiled’ genitalic morphology, as well as several species (e.g. M. linnaei , M. turbans ) with a somewhat intermediate morphology between M. longissimum and those taxa with a simple, looped embolus (e.g. M. bryophilum ).
