Male. unknown.

Etymology.

This species is named after Camelia Lisenchi because of her great support during a collecting trip in Cyprus.

Material examined.

1♀. Cyprus: Holotype 1♀, 6 km N of Lemessos , 34.727°N, 33.05°E, 24.v.2009, leg. Popovici O. and Fusu L. (SN) (OPPC0813).

Distribution.

Cyprus (Fig. 309 ).

Diagnosis.

Fidiobia lisenchiae is similar to F. platystasioides because of the absence of epitorular carinae, the fore wings with very short marginal setae and the notauli slightly dilated posteriorly. These two species are easily separated because the mesosoma is slightly flattened in F. lisenchiae and visibly flattened in F. platystasioides . Also, T2 is transverse in F. lisenchiae and square or nearly so in F. platystasioides . The difference between these two states of T2 is reflected in the ratio of T2:T1. T2 is at most 3 times as long as T1 in F. lisenchiae and at least 4 times as long as T1 in F. platystasioides . The submarginal vein is shorter in F. lisenchiae than in F. platystasioides , with the apex of the submarginal vein hardly surpassing the posterior edge of the propodeum in F. lisenchiae and surpassing the middle of T1 in F. platystasioides . Other subtle differences between these species are the color of the scape and tibia (yellow in F. lisenchiae and dark brown in F. platystasioides ), the sculpture of the dorsal mesopleuron (with few striae and a smooth area in F. lisenchiae and with numerous, dense striae in F. platystasiodes ) and in the sculpture of the lateral pronotal area (sculptured only in dorsal third in F. lisenchiae and in dorsal two thirds in F. platystasioides ).
