Mynott, Julia H, Suter, Phillip J & Theischinger, Gunther, 2017, Revision of the genus Dinotoperla Tillyard, 1921 (Plecoptera: Gripopterygidae) using morphological characters and molecular data: Establishes two new genera, three new species and updates the larval taxonomy, Zootaxa 4224 (1), pp. 1-76 : 29-30

Dinotoperla hirsuta McLellan

( Fig. 14 A–D)

Larva. Remarks. McLellan (1971) described the adult male of D. hirsuta . Hynes (1974) synonymised D. hirsuta with D. eucumbene . Hynes (1978) briefly described the larva of D. hirsuta under the name D. eucumbene . The association of life stages is suggested as being by location, as Hynes (1978) states that he was unable to rear or collect freshly emerged adults. Theischinger (1982) re-instated D. hirsuta and synonymised D. arenaria Hynes (1974) with D. eucumbene .

Material examined: New South Wales: Kosciuszko National Park: 2 x larvae: Eucumbene River at crossing Snowy Mountains Highway . -35.88553, 148.51383. Collected: 5-Jan-13, Collectors: J Mynott & M Carey, Accession numbers: JMH1248, JMH1249.

Length: 6.5–7 mm.

Colour: Light brown; dark mottling on head. Meso- and meta-nota with darker areas and pale bosses at base of wingpads.

Body: Robust; head and pronotum subequal; abdomen longer than thorax.

Head: Pronounced mottling on posterior area of head. Smooth welt-like areas medial to antennae base. Antennae long, darkening in the last third.

Thorax: Pronotum wider than long but not wider than head; dorsal surface with scattered dark spots. Surface of nota with robust setae present, less so on wingpads.

Legs: Outer surface of femora with two dark longitudinal stripes, weaker stripe present on tibiae (usually visible in distal half); inner surface of femora with a dark patch present; tibiae with single dark band in proximal area. Femora and tibiae without fringes of long fine setae on outer margin, some scattered fine setae may be present. Robust setae present on all surfaces excluding inner surfaces.

Abdomen: Sternites 2–6 with reddish spots present (four or two), not always visible. Two dark spots on dorsal surface of tergites, lateral area may have one or two present. Long robust setae present on surface and hind margins of tergites. Paraprocts triangular, long and broad. Gill tuft dense, gills orange. Cerci short, segments elongated from approximately segment 10.
