Redescription.
Length 10.76 mm [10.60-10.87] (n = 3)
Head
(Fig.
8A-D
).
Thorax
(Fig.
8G-K

Acrostichal setae = 0 + 1, dorsocentral setae = 0 + 1, intra-alar setae = 0 + 1, post postpronotal lobe setae = 1 long and 1 short, outer post postpronotal lobe seta present, supra-alar setae = 2, marginal scutellar setae = 3, discal scutellar setae = 0, proepisternal setae = 2, proepimeral seta = 0. Proepimeron, proepisternum, anepimeron, anepisternum, katepisternum and inferior half of postpronotal lobe covered with dense yellow microtomentum (Fig.
8J, K
); meron also covered, but with microtomentum lighter, anepisternal setae = 2 anterior to an extra dense row of yellow hairs (Fig.
8J, K
).
Wing
. Tegula and basicosta black-brown, outer margin along costal vein light infuscate, lower calypter yellow and slightly longer than broad.
Legs
(Fig.
8J, K

Abdomen
(Fig.
8E
. F). Yellow-orange, longer than broad.
Male
(n = 2).
Head
(Fig.
8A, C
). Eye bare, inner facets moderately enlarged but not demarcated from outer ones. Eyes separated by 0.04 times width of head [0.04-0.04] (at narrowest point between 1.10 to 1.30 times anterior ocellus width); eye length 3.51 times height of gena [3.49-3.54]. Postpedicel length 2.52 times length of pedicel [2.44-2.61], ocellar setae well-developed, inner vertical seta present, outer vertical seta absent, 8-10 frontal setae, palpus width in broadest area around 2.50 times width of postpedicel.

8J
). Fore tibia with 2-3 anterodorsal setae; mid-tibia with 1 anterodorsal seta, 1 posterodorsal seta; hind tibia with 3 anterodorsal setae (row-like), 3 posterodorsal seta (row-like), 2 anteroventral setae.
Abdomen
(Fig.
8E, J
).
Terminalia
(Fig.
9
). Medial lobe 0.5 times width of sternite 5, posterior margin straight or almost straight and less sclerotised, area that connects with outer lobes densely covered by black hairs (Fig.
9F
). Outer lobes longer and narrow, curved in proximal direction (like an open
'C'
), terminal area round, covered by long and thick black setae, surrounded by a lighter halo with yellow vestiture (Fig.
9F
). Sustylus rectangular (Fig.
9A, B
), thinner and more slender than in
F. albitarsis
(Fig.
6A, B
), posterior area darker (Fig.
9A, B
), ventrally and dorsally with black setae (Fig.
9A, B
), in lateral view (Fig.
9B
) slightly curved inwards at ventral posterior region and proximally pointed (Fig.
9B
). Cercus slender and fused, covered with long black setae, forming an inward hook apically (Fig.
9B
). Phallus as in Fig.
9C-E
, ventral plate in ventral view as in Fig.
9E
; postgonite and pregonite as in Fig.
9C-E, G
.

Discussion.
We were not able to examine the type material of
Fainia elongata
or
Idiella major
, but
F. elongata
is a well-defined species, properly described by
Bezzi (1908)
and diagnosed by
Peris (1952)
and
Zumpt (1958)
. The synonymy was first published by
Peris (1952)
and seems reliable.
