Discussion. This species is an arboreal Palaearctic faunal element. It has been reared from mosses covering a log at a lake margin and from wet soil (present observation). Records based on females from England ( Edwards 1926) and Zaire ( Goetghebuer 1933b) are doubtful. The occurrence of this species in Hungary, reported by Zilahi-Sebess (1940), was confirmed by Remm (1973b).

Goetghebuer (1934a) and Remm (1988) synonimized Prokempia halobia with D. flaviventris (subgenus Prokempia ) while Borkent & Wirth (1997) placed it among synonyms of D. flavoscutellata (subgenus Pseudoculicoides ). According to the original description, it is similar to D. flaviventris but the latter species was never collected in saline habitats. It is possible that D. halobia from saline habitats (types lost) actually belongs to the subgenus Pseudoculicoides as suggested by Borkent & Wirth (l.c.) (see also D. halobia among nomina dubia).
