there is the combination of characters: the two or three sternopleurals + shortened hind metatarsus + 2 vibrissae + bare mesopleuron which suggest me the species group or subgenus (Leriola). There are two species with such chaetotaxy: S (L.) collini Woznica 2004 with totally orange or reddish oalpus and S. (L.) brachypterna (Loew) with bicoloured palpus (blackish-yellow) ;)
