Gastrothrips

This genus is found worldwide throughout the tropics. It currently includes 37 described species, and these live on dead twigs and branches. The Neotropical species usually have the tube constricted apically, whereas the Palaeotropical species usually have the tube with straight, tapering sides. Structural variation between samples is particularly difficult to interpret among these Palaeotropical species. For example, G. acutulus Okajima , recorded from southern Japan (Ryukyu Islands), Taiwan, Philippines, Sabah, Thailand and Peninsular Malaysia ( Okajima, 2006), is possibly the same species as G. falcatus Ananthakrishnan from India. The large males of this species have a remarkable prolongation posteromedially on the metanotum. Also recorded from Peninsular Malaysia is G. acuticornis Hood , a species that was described from the West Indies but is known from northern Australia and New Caledonia. The only other species recorded from Southeast Asia is G. curvidens Karny from Java.
