Forster & Platnick, 1984: 92, figs 360–361, 369–370, 375–376. Micropholcomma longissimum(Butler): Davies, 1985: 89. Platnick, 2009.
Typematerial. Holotypemale: Mount Donna Buang, near Warburton, Yarra Ranges, Victoria, Australia, under logs and similar places, 4080 ft, II.1931, C. Oke( NMV K103). Selectedmaterial examined. AUSTRALIA: Victoria: Yarra Ranges, Toolangi State Forest, 3 kmE. of Toolangi, 15.I.1990, D. Black, 1♀( WAMT94464); Yarra Ranges, White Hill Track No.2, 15 km ENE. of Healesville, on Acheron Way, 4.III.1990, D. Black, 2♀( WAMT94465); same data, 2♀( WAMT94466); Double Creek Nature Walk, 7 kmN. of Mallacoota, 26.X.1990, D. Black, 2♁, 1♀( WAMT94469); 10 kmENE. of Genoa, near Johnson’s Bridge, 26.X.1990, D. Black, 1♁, 1♀( WAMT94468); Great Otway National Park, track to Cora Lynn Cascades, near Lorne, 22.IV.2006, M. Rix, 1♁ ( WAMT94463); same data, 1♁ ( WAMT80018 DNA- MPE); Mount Buffalo National Park, walking tack to Eurobin Falls, 8.V.1990, D. Black, 2♀( WAMT94467).
Remarks. Micropholcomma longissimumis 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 Micropholcommain both eastern and south-western Australiathat 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. longissimumand those taxa with a simple, looped embolus (e.g. M. bryophilum).
