Distribution.

India (Uttar Pradesh, West Bengal); Thailand (Chiang Mai, Nakhon Sri Thammarat) ( Beaver and Gebhardt 2006). New to China (Sichuan, Yunnan).

Diagnosis.

The male appears to be related to S. reticulatus which has a similar prosternum (compare figures 1K and 1L in Beaver and Gebhardt 2006). The females are also very similar, but the female of S. reticulatus lacks the typical mycangial pore on the pronotum.

Host.

Recorded from species of Alnus ( Betulaceae ), Cornus ( Cornaceae ), and Prunus ( Rosaceae ) ( Beeson 1961), Cinnamomum ( Lauraceae ) ( Beaver and Browne 1975), and Acrocarpus ( Leguminosae ) ( Saha and Maiti 1996). Evidently polyphagous. In Thailand, the species was found in smaller branches (1-2 cm diameter) of Cinnamomum iners Reinw. ex Bl. than those attacked by S. raja and S. pubescens ( Beaver and Browne 1975).
