Erigomicronus lautus ( Saito, 1984) new combination

( Figs 5 , 10 )

Maro lautus Saito, 1984: 2 , figs 1, 2, (m, f); holotype deposited in NSMT, not examined .

Maro lautus Ono, Matsuda & Saito (2009) : 318, figs 867–868 (m, f).

Type material examined. 1 male and 2 females paratypes of Maro lautus ( NSMT, Art. 858), Japan, Oku-Ni-kko, Tochigi Prefecture, 21.V.1983, H. Saito leg.

Diagnosis. Males can easily be distinguished from its single congener, E. longembolus new combination, by

the shorter distal suprategular apophysis and the question mark-shaped distal part of the convector which looks like a lamella characteristica. The females can be separated by the shape of the protruded anterior wall of the epigynum: narrowed and rounded in E. longembolus new combination, shorter and truncated in E. lautus new combination (cp. Figs 6 and 10 , as well as cp. Fig. 10 and fig. 22 in Marusik et al. 2016)).

Description. The species was well-described by its author, Saito (1984), an additional illustration of the palp and epigynum ( Figs 5 , 10 ).

Note. The types were received on loan and examined in 2005–2006 by both late Michael Saaristo (Zoological Museum of the Turku University, Turku, Finland) and myself during our long collaboration on the taxonomy of the subfamily Micronetinae .

Distribution. Japan ( Saito 1984).
