Diagnosis. A large and robust species (body length: 16.5–20.7 mm) with greatly elongate, anterolaterally directed and apically usually recurved humeral processes ( Figs 80–83 View Figs 80–83 ). The diagnostic male terminalia ( Fig. 15 View Figs 11–19 ), paramere ( Figs 40–41 View Figs 20–44 ) and female terminalia ( Fig. 54 View Figs 52–55 ) are illustrated in the present paper.

Bionomics. Eight adults and four larvae examined by us were collected from the endemic Formosa firethorn, Pyracantha koidzumii (Hayata) Rehder (Rosaceae) during a single collecting event; the collector informed us that he has observed them to feed on the fruits (C.T. TANG, pers. comm.). ZHANG et al. (1980) reported the species from the broad bean, Vicia faba L. ( Fabaceae ) from Zhejiang but this host plant record seems doubtful.

Distribution. Acanthosoma laevicorne has been recorded from a number of localities in southern China but it is apparently rare everywhere. It was listed from Shandong by HUA (2000) but this record was based on an unclear source and it seems questionable. DISTANT (1902) recorded it from ‘North-west Provinces’ of India; we present the first precise locality from the Indian Subcontinent. The species was listed from Japan by HSIAO & LIU (1977) and subsequent Chinese authors; as no Japanese authors have ever reported it from the country these records are considered as erroneous.A single old specimen from ‘Tonkin’ was examined by us and we consider this record as the first record for Vietnam. We present the first record from Taiwan.

Remarks. Acanthosoma laevicorne was described based on an unspecified number of males and females collected at an unknown locality by Th. Hardwicke ( DALLAS 1851). A male and a female syntype were located in the BMNH, and the male ( Figs 92–93 View Figs 92–99 ) is hereby designated as lectotype.

The species is related to A. rufispinum (Distant, 1887) and A. tauriforme (Distant, 1887) ; the three species apparently form a monophyletic group (called here as the A. laevicorne group) based on the following combination of characters: head triangular, pointed (mandibular plates narrow, clypeus surpassing them apically); stongly prolonged, sword-shaped, apically recurved humeral process; similar shape of genital capsule (with an extension of the dorsal wall over the ventral infolding and a pair of protuberances on the ventral rim laterally); similar shape of paramere. Acanthosoma laevicorne differs from the other three species by the presence of a distinct tubercle on the maxillary plate anteriad and mesad of antennal insertion, the greatly produced mesosternal carina far surpassing middle of head, and its male and female terminalia. The other two species were illustrated by TSAI & RÉDEI (2015b).
