The Hermite Island Worm-lizard is a pale brown reptile growing to 9.5 cm with a broad dark stripe on either side of the neck. Its head is finely reticulated with darker brown, with three dark fine lines on the nape. Its underbody is whitish with a fine brown line on each side of the belly. It has a slender body and a relatively pointed snout (Cogger 2000).

This species is known only from Hermite I., Monte Bello Group, NW WA (Cogger et al. 1993). Collected on a single occasion in 1952, not recorded in surveys in 1914 or 1970 (Hill 1955; Burbidge 1971; Cogger et al. 1993). The first systematic surveys of the Monte Bello I. Group involved pitfall trapping in 1994. In that year 11 trap sites were established and run between 22 May and 7 June on nine islands: Hermite, Ah Chong, Alpha, Bluebell, Brooke, Crocus, Delta, North West, and Primrose. Despite this trapping and searching in litter, soil, and under debris, no specimens were found (Burbidge et al. 2000).

Storr et al. (1990) considered the Hermite specimen to be a full species (A. rostrata).

The island is comprised of highly calcareous sandstone, the higher parts are rocky with other areas consisting of flat, dried mud, like the bed of a dried-up lake (Hill 1955; Cogger et al. 1993). Triodia hummock grassland is dominant on much of the island, with shrubs, tussock grasses and herbs growing in the gullies (Burbidge 1971). Due to strong winds in the area, the tallest shrubs in open areas are limited to below approximately 120 cm in height. A common shrub in such areas is Acacia coriacea (Hill 1955).

The species has a sharply protrusive snout, which may indicate considerable time spent deep within the substrate (Wilson & Knowles 1988).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
