Etymology. This species is named for one of the collectors of the holotype, Stephen E. Thorpe.

Diagnosis. This species can be distinguished from the other species of the hirtalis speciesgroup by the following combination of characters: antennomere 1 elongate, approximately 3 times longer than wide; antennomere 4 elongate, approximately 1.5 times longer than wide; posterior frontal fovea elongate; eye small, one-third length of temple; hind wings well-developed; shape of genitalia unique to species.

Description. Length 2.7–3.2 mm. Body brown, elytra, legs, and maxillary palpi paler ( Fig. 3i ). Head: As long as wide, widest across eyes ( Fig. 3i ). Antennomere 1 approximately 3 times longer than wide, 2–3 subquadrate, 4 elongate, 5–6 longer than wide, 7–9 subquadrate, 10 transverse. Frontal sulcus deep and reaching behind eye from end of frontal rostral lobes. Anterior frontal fovea oval, posterior frontal fovea oval. Eye small and prominent, one-third length of temple. Thorax: Prosternum as long as wide, widest at one-third length. Elytra rectangular ( Fig. 3i ). Hind wings well-developed. Meso- and metathorax trapezoidal, longer than wide. Abdomen: Tergite IV with pair of transverse, reaching middle, patches of microtrichia. Aedeagus: Median lobe longer than parameres with semicircular apical lobe ( Fig. 4i ). Phallobase of median lobe asymmetrical and triangular ( Fig. 4i ). Left paramere divided into 2 branches from base, with minor branch divided into 2 branches apically ( Fig. 4i ).

Distribution. Coromandel ( Fig. 6 : black squares).

Habitat. Specimens were collected using yellow pan, Malaise, and pitfall traps.
