Aedeagus (aed) strongly curved, perhaps 100 µm long, with parallel sides when viewed dorsally, widening at both ends, distal end rather shovel-like; anteriorly, aedeagus bends ventrally and fuses with a short sclerotised basal rod (bra).

are typical rhizoecine males, differing from those of other species seen here in having the following combination of character states: (i) tarsal digitules probably capitate, (ii) antennae long, with some segments bottle-shaped and most setae appearing to be in whorls, (iii) trochanter with 3 pairs of campaniform pores; (iv) trochanter with strong Y-shaped sclerotisations; (v) aedeagus broadening at apex, and (vi) shape and structure of the penial sheath, particularly the ventral internal extension.
