Additional description
. Male.
Head
. Eye bridge 2 facets wide; frons between eye bridge and scape with a few bristles. Antenna short; 4th flagellomere with l/w-index of 1.4, with hairs pale, bristle-like and nearly as long as the width of the basal node; necks rather short, brownish; palpus 3-segmented; basal segment without sensory pit, with 4-5 bristles.
Thorax
. Scutum with rather short and brown central as well as lateral bristles; scutellum with 2 long and 4 shorter marginal bristles; postpronotum bare. Wing brownish; R1 = 1/2 R; R5 throughout with macrotrichia dorsally and ventrally; C = 3/4 w; y = x, with 1‒2 macrotrichia; M-fork long, posterior veins without macrotrichia. Haltere short, brownish. Legs brownish; tibial organ small, with 4‒5 fine hyaline bristles in an irregular row; spurs of middle and hind tibia equal in size, longer than the width of apex of tibia; claws missing.
Abdomen
. With rather long, dense brownish hair. Hypopygium with broad open ventral base, without lobe or patch of bristles; gonocoxite with short and sparse hairs on the inner ventral margin; gonostylus curved in the apical third, densely hairy on the apex, with 2 subapical spines as long as apical hairs, and with a long whiplash hair below; tegmen wider than long, with dark sclerotized shoulders laterally, rounded apically; aedeagus rather short, with large furca. Body length:
2.2 mm

Comments
. This species is characterized by very short flagellomeres, frons with short bristles, gonostylus with 2 short spines and a much longer whiplash hair, and a tegmen that has rather strongly sclerotized shoulders. The
type
specimens of
S. familiaris
and
S. festiva
are in rather good condition. Both are identical to
Psl.
cavatica
(
Skuse 1888
)
in all details.
