   Holotype NMV T.8122 ♂ (coll.: 23.xi.1965, Neboiss), Mallacoota, Victoria.

Introduction

One of the smallest Australian flatids and a member of the granulicollis group which can only be differentiated by examination of the structures of male genitalia, particularly the apical processes of the phallosoma which extend beyond the apex of the aedeagus. The name is derived from the Greek word for "surprised", a reference to this arrangement of aedeagal processes.

Diagnosis

granulicollis Group. Head short, frons longer than widest part which is level with antennae. Vertex with apical margin evenly rounded or obtusely angulate. Apical and basal margins of vertex more or less parallel. Tegmen with apical and sutural angles rounded. Costal margin convex throughout, more strongly so on basal half, so that widest part of tegmen at about midlength. Clavus long, extending nearly to sutural angle, so branching of M1+2 well basal of claval apex. Colour green, fading to yellow or orange in dried specimens. Apex of head, fore- and mid-tibiae externally and usually tarsi, red. Tegmen usually with red border from apex of costal cell around apical margin and claval margin to apex of clavus, this border interrupted by green vein endings. Outer claval vein usually red. Tegminal granules black.
S. thambeos. Male abdomen dark. Male pygofer with blunt triangular process. Paramere narrow with prominent blunt process. Female third valvulae blunt with pilose area ventral. Second valvulae gap oval, inner margins of valvulae roundly converging apically (Fletcher 1985).
