Matronoides View in CoL

Just one larval specimen of this monotypic genus is known ( Orr & Price 2022). Matronoides cyaneipennis Förster is endemic to altitudes over 900 m in North Borneo and in some localities may occur together with Neurobasis longipes Hagen (R.A. Dow pers. comm.). The adults are reliably seen on Silau Silau Creek in the Kinabalu National Park, Sabah, and presumably diligent searching among leaf packs and submerged bankside root masses would produce more material. The larva is of a heavier build than those its sister genus Neurobasis , but the prementum is relatively longer and narrower than in any known Neurobasis species ( Fig. 29 View FIGURES 27–34. 27 ). There is also heavier serration on the outer rib of the external caudal lamellae.
