Issus fissala Fieber, 1876: 259, [separata 1876: 249] (Figs 9; 10 A, B)
Type material examined. Lectotype (here designated) (MNHN (EH) 7480) (specimen without abdomen), with Noualhier’s hand-written label: “ Type Fieber” (NLC).
Note. The species was based on a male (or males) from Portugal (in Fieber’s manuscript: “Aus Portugal (Fieber)”). The specimen from NLC corresponds to Fieber’s drawings and this is here designated as lectotype. I. fissala belongs to the Oriental genus Thabena Stål, 1866, redefined recently by Gnezdilov (2009), according to the features: metope with median carina crossed by transverse carina below its upper margin, fore wings narrowing apically, without hypocostal plate, clavus with cuspidal caudo-dorsal angle, hind wings well developed, bilobed. Fieber figured a very wide male anal tube which is also a characteristic feature of some species of the genus Thabena.
