Rohde (♀ holotype) ( RBINS) .

Remarks. P. shoutedeni was described from only one female. According to Griffini (1908) it differs from P. adeps Karsch, 1896 by the number of veinlets branching off from the radial vein of tegmina ( Figs 14A, 14B ). They are three, all placed after the centre of tegmina; however, in P. adeps this character is variable, generally there are three, but some specimens may have two or four. The fastigium of vertex of P. shoutedeni is ca. two times as large as the first antennal segment ( Fig. 14C ), while in most P. adeps it is three times as large as the first antennal segment ( Fig. 14D ); however, this character may be also variable and some specimens of P. adeps may present a fastigium less large. Also the ovipositor of the two species resulted very similar ( Figs 14E, 14F ). For these reasons it is here that a new synonymy is proposed: Plangiopsis shoutedeni Griffini, 1908 = Plangiopsis adeps Karsch, 1896 .
