Remarks. 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   ).
