Distribution in Iran . Golestan ( Abd-Rabou & Ghahari 2006 ). General distribution. Nearctic; introduced to some regions of the Palearctic. Comment. This species was identified upon only a single specimen caught in semi-desertic conditions on Abutilon theophrasti (Malvaceae) ( Abd-Rabou & Ghahari 2006 ). J. spinosus has a more restricted area in USA and feeds mainly on panic grasses ( Panicum spp., Poaceae ) ( Wheeler & Henry 1981 ). Another species, J. wickhami Van Duzee 1906, is a polyphagous bug, widely distributed in America and Mexico and more probably in some regions of the Palearctic. Additionally, the metacanthine berytids, including Jalysus species, develop mainly on well-glanded, pubescent hosts, feeding preferentially on glandular hairs or on arthropods entrapped by plant secretions ( Wheeler & Schaefer 1982 ; Wheeler 1994 ). Many stilt bugs have greatly developed ostiolar processes that may extend upward and well above the hemelytra. The ostiolar process in the metacanthine genus Jalysus ends in a sharp spine, whereas these processes in Metacanthus and Pneustocerus extend outward, then curve posteriorly before ending in a rounded apex ( Schaefer 1972 ; Henry 1997a ).
