Type species: Accacidia dlabolai Dworakowska, 1971 , by original designation

Description. Body usually robust and short, mostly 2.0 to 3.0 mm. Head including eyes usually as wide as or wider than pronotum, crown fore margin angulately produced or rounded apically, coronal suture visible at least basally. Ocelli rudimentary with elongated, crescent-shaped vestiges. Face somewhat convex in profile. Forewing ( Fig. 9a ) with four apical cells almost equal in length and width, AA and AP indistinct or fused. Hind wing ( Fig. 9b ) with or without RA.

Male abdominal apodemes 2S well developed, narrow to wide, extended to sternite IV–VII. Anal tube with appendages basally.

Male genital capsule usually spherical, weakly sclerotized. Pygofer lobe with spicules on distal half, with some fine setae usually near ventral margin, sometimes with several rigid microsetae near caudal margin; usually without dorsal appendage; with or without ventral appendage. Subgenital plate surpassing hind margin of pygofer lobe, slightly infuscated, widened subbasally, usually angulately produced, with about 2–3 macrosetae subbasally near outer margin, with 2 rows of stout setae on subbasal angle and continued with row of rigid microsetae to apex, with some microsetae scattered on distal disc. Style with apical part foot-like, with transverse furrows, preapical lobe well developed, usually with sensory setae both on preapical lobe and basally of middle part. Connective V-shaped, manubrium usually narrow, with or without central lobe. Aedeagal shaft tubular, with pair of thin processes apically in most species; dorsal apodeme well developed, usually narrow and long in lateral view; preatrium short, with very long preatrial process, usually with whorl-like sculptures apically; gonopore apical or subapical, on ventral side.

Distribution. Austria; Burkina Faso; Republic of Congo; Egypt; Ethiopia; Germany; India; Israel; Jordan; Pakistan; Saudi Arabia; South Africa; Sudan; Uganda; Yemen.

Diagnosis. This genus is similar to Singapora Mahmood, 1967 , but the vertex lacks a dark spot apically, the ocelli are rudimentary, the subgenital plate lacks marginal macrosetae subbasally, the style is shorter and the aedeagal shaft is fused with the preatrium.
