Material. Holotype: elytrous male, MEQ, Cape Hillsborough, 20° 55’S 149° 03’E, 20m above sea level, 16 Apr 1979, G. Monteith, open forest sieved litter berlesate QM27, HILL 00044, T 228948 in QM whole in one vial.

Paratypes: 1 elytrous male, MEQ, Cape Hillsborough, 20° 55’S 149° 03’E, 10m above sea level, 16 Apr 1979, G. Monteith, open forest sieved litter, QM29, HILL 00046, T 228949 in QM on 3 slides;1 elytrous female, MEQ, 2.5km ESE Eungella, 21° 08’S 148° 31’E, 200m above sea level, 18 Nov 1981, A. Gillison, tall open woodland berlesate sample C24, HILL 00045, 20-007842 in ANIC whole in 1 vial.

Description. Male brown; frons pore in ventral surface of protruding hood, without transverse carinae below pore; ratio of lengths pronotal collar to entire pronotum 0.24–0.26; left paramere 0.39 mm, unstraightened vesica 0.32 mm long, probably not apically bifid. Female brown; frons without pore or hood, without transverse carinae; ratio lengths pronotal collar to entire pronotum 0.29; with V-shaped impression posteriorly on S7.

Etymology. The specific epithet means ‘bearing a hood’ alluding to the hood on the frons of males.
