( Fig. 29 ) Material examined. YEMEN : AL HUDAYDAH GOV.: 1♀ , Jabal Bura valley forest NP, 14°52ʹN , 43°24ʹE , 261–600 m , 9.–11.iv.2007 , S. Kadlec leg. ( NMPC ). Notes. A single female (body length 15 mm ) cannot be identified within any of the known Dineutus species from the region. It is characterised with relatively elongate habitus with sides of elytra only weakly rounded and feeble subapical elytral sinuation; greenish lustre of dorsal surface and well visible elytral striae. Finding more specimens, especially males, is necessary for solving its classification.
