DIAGNOSIS: Recognized uniquely among its congeners by appressed, flattened black setae on dorsum; membrane pale with a faint infuscate mark at apex of cells (pl. 28); distal portion of sigmoid endosoma with very large, undulating, strongly microtrichiate sclerotized plate, left ventral edge of plate forming narrow microtrichiate ribbon; endosoma with long reflected lateral spine on dorsal margin, short reflected apical spine, and two medial spines ventrad of secondary gonopore (fig. 82, pl. 29). Endosoma with long lateral spine at midpoint, similar to S. eremophiloides , but that species with a contrasting spot on corium at inner angle of cuneus, distal microtrichiate plate of endosoma without ribbonlike extension, and a long erect spine just distad of secondary gonopore and proximad of dorsal margin of microtrichiate sclerite.

DESCRIPTION: MALE: Mean total length 2.68, mean pronotum width 0.87. COLORATION (pl. 28): Yellow, including all appendages (in preserved specimens); corium without infuscate mark adjacent to inner angle of cuneus; membrane pale with a faint dark marking at apex of cells. SURFACE AND VESTITURE (pl. 28): Dorsum clothed with appressed, black, weakly flattened setae. STRUCTURE: Head (pl. 28): Eyes in lateral view occupying two-thirds height of head; antenna inserted at ventral margin of eye, eye not emarginate; antennal segment 2 short (0.50), 0.76 times width of head; labium reaching posterior margin of mesosternum. Thorax (pl. 28): Pronotum with lateral margins nearly straight, posterior margin very weakly concave; meso ‐ scutum broadly exposed. Hemelytron: Short, corial margin weakly convex. GENITALIA (fig. 82, pl. 29): Pygophore: As in generic description. Endosoma: Sigmoid; ventral strap with short, stout bifid subapical spine, terminating at proximal margin of secondary gonopore in a fingerlike projection; dorsal strap with long reflected lateral spine at midpoint and short obscure spine apically; flattened apical plate large with undulating margin covered with strong microtrichia, left edge attenuate, forming microtrichiate strap. Phallotheca: Dorsal crest prominent; basal portion with transverse ridge on right margin. Parameres: Left paramere with dorsoposterior margin slightly elevated dorsad. Right paramere with medially placed ter ‐ minal point.

Female (pl. 28): Coloration as in male; differing from male as in generic description; mean total length 2.45, mean pronotum width 0.84.

ETYMOLOGY: From the Latin, crenulatus, “having a little rounded projection,” in reference to the structure of the phallotheca.

HOSTS: Recorded from Eremophila crenulata and E. fraseri (Scrophulariaceae) .

DISTRIBUTION ( MAP 21 ): Known from the Shark Bay area of Western Australia.
