Colour:
Pale yellowish.
Body:
“Rather flattened dorsal surface is shagreened with closely packed hairs with swollen bases. These hairs resemble exaggerated Indian clubs, or chianti bottles, and they form marked fringes around the nota” (
Hynes (1978)
description as
D. arenaria
, page 46). Often “fuzzy” in appearance as early instar. Broad and swollen robust setae give a scale-like appearance to dorsal surface and legs.
Head:
Dorsal surface covered in swollen setae. Central area of head with a swollen V-shape; ocelli with a weltlike appearance. Antennal segments as broad at pedicle for approximately 30, then taper for 5 or so until segments are typical of the genus (thin and elongate).
Thorax:
Thorax as long as abdomen; distinct and broad. Pronotum with posterior corners produced to points. Meso- and meta-nota with wing pads produced into points (juvenile), widely rounded in later instars. Anterior area and margins of pro- and meso-nota with long fine setae (often curled). Pronotum with a dense fringe of long, robust and broad sickle-shaped setae along all margins. Meso- and meta-nota with long, robust and broad sickle-shaped setae on posterior margin and margins of wingpads.
Legs:
Inner margin of femora and outer margin of tibiae with long and broad robust setae. Outer margin of femora with scattered swollen setae.
Abdomen:
Cerci tiny, segments very thin and elongate, first 5 segments more robust. Tergite X much longer than wide (length:width = 2). Hind margin of tergite with long and broad robust setae. Tergites 2–8 with two medio-lateral spots. Sternites with swollen robust setae present, more densely posteriorly. Paraprocts triangular and long.
