Idiocerus quinquepunctatus Melichar 1903: 146 .

Amritodus brevistylus Viraktamath 1976: 234–235, figs 1–5. Viraktamath 1997: 115, figs 15–21, 27; Xue & Zhang 2020: 1447–1448, figs 5A–N, 14A–G. Syn. nov.

Diagnosis. Very similar to A. atknsoni in coloration, but male style apex not curved, dorsal surface with short thin numerous setae. Aedeagus with shaft about as long as preatrium, with pair of short spine-like basal processes on ventral surface. Female sternite VII 3× as wide as long medially, lateral margins narrowed posteriorly, posterior margin between lobes concave with median concave exaction (Fig. 60K).

Material examined. HOLOTYPE ♀, SRI LANKA: Ceylon, Peradeniya, Jan 1902, leg. Dr Uzel, Dr. Melichar, 5punctatus, det. Melichar, Idiocerus quinquepunctatus Melichar 1903, L. Melichar det. (MMB). INDIA: several male and female specimens from Karnataka, Kerala, Tamil Nadu (UASB).

Remarks. Melichar (1903) described Idiocerus quinquepunctatus based on a single female specimen (holotype, Fig.12A–F) with collection data “Peradeniya, im Jänner 1902 von Dr. Uzel”. Distant (1908) synonymized this species with Idiocerus atkinsoni Lethierry. However, examination of the female sternite VII of the holotype suggests that it is a senior synonym of Amritodus brevistylus Viraktamath. Gnaneswaran et al. (2007) studied several males and females of A. brevistylus from different parts of Sri Lanka including Peradeniya, suggesting that the species concerned is A. quinquepunctatus . The distribution pattern of A. brevistylus, a species found only in southern parts of peninsular India and continuing in Sri Lanka suggests that the species concerned is A. quinquepunctatus, and hence the synonymy. Viraktamath (1976, 1997) adequately described and illustrated the species and Xue et al. (2020) diagnosed and illustrated the male and female genitalia under the name A. brevistylus . It differs from the other three species of Anritodus in having a pair of short spine-like processes on ventral surface of aedeagal shaft at base (Fig. 11H). This species occurs in Karnataka, Kerala, Tamil Nadu and Sri Lanka. It has the same habit as A. atkinsoni and breeds on young leaves and inflorescence of mango. During off-season, the adults are found resting on trunks of mango (Fig. 73B) and neighbouring trees.
