MATERIAL EXAMINED. 1♂, 1♀, Morocco: Fahs-Anjra , Rmel, 27.II.2020, 35°38´57.4´´N, 5°35´41.4´´W, 372 m, M. Nourti leg.

HABITAT. The same as that of Sybistroma parvula ( Parent, 1927) (see below).

NOTES. The species was described from the Sierra Morena mountain range in southern Spain and was probably never reported again until recently. Outside Spain, it was found only in Morocco, on river banks, marshes and dune marshes in Rif Mountains [ Nourti et al., 2019a]. A thorough investigation of the newly collected material has shown that the species morphology corresponds entirely with the generic concept of Ortochile as described by Brooks [2005]. It has proboscis as long as head is high; vein M beyond crossvein dm-m with weak anterior bend before middle, convergent with R 4+5 and ending well above wing apex, close to apex of R 4+5. O. morenae is the fourth known species of the genus and the second species in Morocco. At present it is distributed in Morocco and Spain.

DIAGNOSIS. Ortochile morenae is close to O. nigrocoerulea Latreille, 1809 , differing in shorter proboscis, at most as long as height of head in male, broad palpus, morphology of hypopygium (see key below). The synonymy of O. nigrocoerulea and O. unicolor Loew, 1850 [ Yang et al., 2006; Grichanov, 2007] needs confirmation.
