Diversity of Stilicoderus and Stiliderus

Including the new species described below, Stilicoderus now includes 111 species. Forty-three of them are distributed in the Australian, the remainder in the southern East Palaearctic and Oriental regions. In the Australian region, 31 species have been recorded from New Guinea (13 from West Papua, 17 from Papua New Guinea, and one from both), twelve from Australia, and one from Solomon Islands. In the Oriental and East Palaearctic regions, the countries with the greatest diversity are China (27 species), India (18), Indonesia exclusive of West Papua (14), Thailand, and Burma (13 species each), followed by Nepal (7), Laos (6), Malaysia (6), Vietnam (5), Taiwan (5), Japan (2), Bhutan (1), Singapore (1), and the Philippines (1).

In China, the province with, by far, the greatest number of species is Yunnan (19 species). Significantly fewer species have been reported from Sichuan (6), Shaanxi (5), Gansu (4), Hubei (4), Fujian (2), Guangxi (1), Hainan (1), Henan (1), and Zhejiang (1).

Stiliderus currently includes 52 species mainly distributed in the Oriental region, with some species also occurring in the extreme south of the East Palaearctic regions and one probably adventive species reported from the Comoro Islands. The country with the greatest diversity is Indonesia (22 species), followed by the Philippines (15), Thailand and India (13 species each), Malaysia (5), China (3 species, all of them confined to Yunnan), Laos (2), Burma (1), Hong Kong (1), Vietnam (1), Singapore (1), Japan (1), Sri Lanka (1), and Nepal (1).
