Tonnoiriella filistylis Vaillant & Moubayed, 1987 : Annales de Limnol 23 (2): 124–125.

Material: Holotype, 1♂ collected near Hermel , Lebanon, collected near the spring of a small affluent of the Orontes river at 650 m a.s.l. (17 May 1982) leg. Moubayed (specimen not in the collection Vaillant, probably lost).

Wing length 2.1 mm; relation length by width 2.95

Male terminalia ( Fig. 42 ) with hypandrium linguiform prolonged in the middle. Gonocoxites approximately 1.8x longer than wide; gonostyli longer than gonocoxites, almost straight, apical section suddenly thinner, flattened and with of 4 setae bases in line that are in contact to each other ( Fig. 41 ).

Epandrium rhomboid, apically converging; epandrial processes basally swollen, apically with 3 feathered tenacula, one long and 2 short.

Distribution: Lebanon, known only from the type locality Hermel, collected on the bank of a small tributary of the Orontes river in May 1982.
