Redescription.

Length 10.76 mm [10.60-10.87] (n = 3) Head (Fig. 8A-D View Figure 8 ). Thorax (Fig. 8G-K View Figure 8 ). 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 View Figure 8 ); meron also covered, but with microtomentum lighter, anepisternal setae = 2 anterior to an extra dense row of yellow hairs (Fig. 8J, K View Figure 8 ). 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 View Figure 8 ). Femora yellow, tibiae yellow to brown. Abdomen (Fig. 8E View Figure 8 . F). Yellow-orange, longer than broad. Male (n = 2). Head (Fig. 8A, C View Figure 8 ). 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. Thorax (Fig. 8G, J View Figure 8 ). Legs (Fig. 8J View Figure 8 ). 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 View Figure 8 ). Terminalia (Fig. 9 View Figure 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 View Figure 9 ). 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 View Figure 9 ). Sustylus rectangular (Fig. 9A, B View Figure 9 ), thinner and more slender than in F. albitarsis   (Fig. 6A, B View Figure 6 ), posterior area darker (Fig. 9A, B View Figure 9 ), ventrally and dorsally with black setae (Fig. 9A, B View Figure 9 ), in lateral view (Fig. 9B View Figure 9 ) slightly curved inwards at ventral posterior region and proximally pointed (Fig. 9B View Figure 9 ). Cercus slender and fused, covered with long black setae, forming an inward hook apically (Fig. 9B View Figure 9 ). Phallus as in Fig. 9C-E View Figure 9 , ventral plate in ventral view as in Fig. 9E View Figure 9 ; postgonite and pregonite as in Fig. 9C-E, G View Figure 9 . Female (n = 1). Head (Fig. 8B, D View Figure 8 ). Eyes separation 0.20 times width of head, eye length 3.12 times height of gena. Postpedicel 2.08 times length of pedicel; frontal vitta subparallel-sided; fronto-orbital plate 0.60 times as wide as frontal vitta at tip of ocellar triangle; ocellar setae well-developed and proclinate, 11 frontal setae, 5 or more proclinate orbital setae, 1 reclinate orbital seta; palpus width more than 2.00 times postpedicel width in broadest area. Thorax (Fig. 8H, K View Figure 8 ). Legs (Fig. 8K View Figure 8 ). Fore tibia 2 anterodorsal setae; mid-tibia 1 anterodorsal seta, 1 posterodorsal seta, 1 anteroventral seta, 2 posteroventral setae; hind tibia 2 anterodorsal setae, 2 posterodorsal setae, 2 anteroventral setae. Abdomen (Fig. 8F, K View Figure 8 ). Tergite 5 with a triangular middle incision (Fig. 8F View Figure 8 ).

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.
