Soractellus Evans 1966: 225. Type species: S. brunneus
Description. Body length. Male 2.2−2.3 mm, female 2.5−3.4 mm.
Coloration: general coloration yellowish with brown markings.
Head: Head longer than pronotum; vertex produced medially, slightly concave, longer than width, rounded to face in lateral view; gena incised with single fine erect seta near to lateral frontal suture; lateral frontal suture reaching ocellus and directed mesad of ocelli; frontoclypeus length longer than wide; clypellar suture slightly arcuate and complete; clypellus width wider than lorum at base, slightly tapered from base to apex, not extending beyond gena with apical margin straight; lorum widely distant from gena margin; ocelli located at anterior margin of head; antenna inserted near lower corner of eye in facial view.
Thorax: Pronotum wider than long, sides short without a carina, anterior margin convex and posterior margin slightly concave. Scutellum shorter than pronotum, with transverse suture.
Wings: Macropterous or brachypterous; with three closed anteapical cells; appendix restricted to anal margin.
Legs: Profemur row AM with AM1, one intercalary row with more than six fine setae gradually reduced apically, two dorsoapical setae; protibia with dorsal surface rounded, setal row formula 1+3, AV row with numerous macrosetae gradually decreasing in size basally; mesofemur AV row with stout and short setae, two apical setae; mesotibia setal row formula 3+3, AV row with numerous macrosetae; metafemur setal formula 2+2+1; metatibia PD row with long and short macrosetae, AD row with macrosetae and one smaller intercalary setae between each pair; AV row with numerous macrosetae extending nearly to base, gradually increasing in size apically; metatarsomere I as long as tarsomeres II plus III combined.
Male genitalia: Pygofer with well-developed macrosetae distally; genital valve triangular; subgenital plate parallel sided, rounded apically, with numerous fine moderately long setae near margin; connective loop-shaped with stem short or absent; style narrow; aedeagal shaft membranous with a pair of basal ventral processes.
Female genitalia: Pygofer with few macrosetae; first valvula with overlapping scale-like sculpture to dorsal margin (Fig. 3D); second valvulae blade-shaped with numerous fine teeth in distal half following anteriorly a dorsal hyaline and sclerotized region (Figs 3E, F).
Distribution. Two species, one (S. brunneus) from Australia and the other (S. nigrominutus) from the Southern Palaearctic and throughout the Old World tropics.
