  Type data:

   Holotype SAMA 21157 ♂ (coll.: 26.xi.1948), Myponga, South Australia.

Introduction

As its name implies, this is a very small species of Siphanta and it is restricted to Kangaroo Island and nearby parts of the Fleurieu Peninsula in South Australia. It belongs to a closely similar group of species, termed by Fletcher (1985) as the granulicollis group most of which can only be distinguished by examination of the male genitalia.

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. parva. Abdomen of males with tergites and sternites dark brown. Male pygofer with long narrow process extending to at least ½ length of paramere. Paramere narrow with pointed apex and incurved process perpendicular to dorsal edge of paramere. Female third valvulae triangular with pilose area ventral. Second valvulae gap U-shaped, parallel-sided (Fletcher 1985).
