Figs 1–20
Differential diagnosis
Pneumia fuehzulii sp. nov. resembles P. canescens (Meigen, 1804) in body size, as well as wings, and less distinctly visible characters, such as the shape of aedeagal complex. It clearly differs by stronger CuA 2 (Fig. 13), M 3, CuA 1 and CuA 2 not touched basally. Hypandrium with two swellings in the middle and a deep cleft between them (Figs 8, 16). Gonostyli almost straight (Figs 8, 17–18), distiphallus straight, pointed, extending a little beyond the parameres (dorsal view). Parameres sickle-shaped (Figs 19–20). Apertures of the epandrium small, circular. Remainders of ventral epandrial plate V-shaped, conspicuous (Figs 7, 15). Pneumia canescens is readily distinguishable by CuA 2 not strengthened (Jung 1956: 235, fig. 128). M 3, CuA 1 and CuA 2 touched basally. Hypandrium broader in the middle (Jung 1956: 235, fig. 130; Vaillant 1979: tab. lxxxiv, fig. 9). Gonostyli bent (Vaillant 1979: tab. lxxxiv, fig. 9), distiphallus straight, pointed, as long as the parameres, not sickle-shaped. Basal two apertures of epandrium conspicuous (Vaillant 1979: tab. lxxxiv, fig. 9). Remainders of ventral epandrial plate not detected.
Etymology
This species is named in honour of the famous medieval Turkish-Azerbaijan poet Məhəmməd Süleyman oğlu Füzuli.

Description
Male
HEAD. As long as broad (Fig. 1); vertex conically inflated with numerous setae, alveoli almost irregularly spaced over its entire surface, with 3–4 supraocular bristles on dorsal margins of eyes on extreme lateral sides of head. Horizontal border of setae above the upper apices of the eyes developed, slightly convex in the middle. Eyes separated (Figs 1, 9); interocular suture conspicuously sclerotized, inverted V-shaped, sclerotized parts gradually tapering from eyes to median, not fused medially, connected by thin ligament. Eye bridge with 5 facet rows (Fig. 9), divided by the approximate width of 4 facet diameters. Ratio of distance of apices of eyes (tangential points) to minimum width of frons approximately 3.5:1. Frontoclypeus (Fig. 1) with a large almost oval central patch of irregular insertions of setae with narrow medial lobe prolonged to interocular suture. Antennae with scape, pedicel and 14-segmented flagellum (Figs 2, 10) haired. Sensory filaments (ascoids) not observed. Scape a little prolonged, barrel-shaped, 1.2 times as long as ovoid pedicel. Both parts with many narrow scales (for size, see Fig. 2). First flagellomere cylindrical (1.1 times as short as pedicel), medial flagellomeres decreasing in size, spindleshaped. Apical progressively bulbous, with a globular apiculus (digit), excentric, 2.1 times as short as the bases bearing them. Mouthparts hardly extend beyond basal palp segments. Length ratios of palpus segments 1.0:1.0:1.2:1.8; last palp segment annulate (Fig. 3). For the terminal lobes of labium, as shown in Fig. 4, lines of spines between both lobes are developed, tongue protuberances in between distally are inconspicuous. Cibarium proximally with a pair of conspicuous bent sclerotized arms, ratio of maximum length of cibarium to length of epipharynx 2.4:1 (Fig. 11), labrum pointed.
THORAX. Anepisternum setae patch almost semicircular between spiracle and wing insertion (Fig. 5). Spiracles set high on mesothorax. No thoracic allurement organs, anepimeron with triangular setose patch. Wings (Fig. 13) ovoid, 3.3 mm long in holotype, 3.0– 3.1 mm in paratypes, rounded distally, inconspicuously expanded at posterior margin. Membrane of wing generally clear; however, sometimes distal part of cell, fork areas, ends of all veins excl. Sc and middle part of CuA 2 clouded. Strengthened parts of veins: Sc, R 1 (not the start), R 2+3, basal cell, R 5, whole CuA 2 and almost all wing veins distally. Radial and medial forks arise at the same level, both forks conspicuously in a basal position to end of CuA 2. R5 ends slightly beyond wing apex. Bases of M 3, CuA 1 and CuA 2 are not connected. Wing index (wing length to width) 2.5. Halteres (Fig. 12) stick-shaped, symmetrical in longitudinal axis, bent and haired, with mass of sensory scales subapically. Ratio of maximum length of halteres to their maximum width 2.7:1. Length ratios of femora, tibiae and first tarsomeres: P 1 2.1:2.3:1.0, P 2 2.3:2.8:1.1, P 3 2.7:3.5:1.2. Paired tarsal claws of P 1 conspicuously backward hooked (Fig. 6) with ventral teeth.
MALE GENITALIA. Basiphallus of the male aedeagal complex (Figs 8, 19–20) straight from dorsal view (incl. some small differences – Fig. 19), proximally spoon-shaped, triangular, narrowed and edging distally (Figs 8, 19), with longitudinal rib proximally, a little arched in lateral view (Fig. 20). Spatula modified from two broad rectangular bases to a parallel inner deep cleft (Figs 8, 19). Distiphallus straight, pointed, bent dorsally in lateral view (Fig. 20), extending a little beyond the parameres (however, distiphallus sometimes two times longer – see paratype Cat. No. 34953 and Inv. No. 26010 from AZE Loc. 25). Parameres sickle-shaped (Figs 19–20). Ratio of length of gonocoxites to length of aedeagal complex (incl. basiphallus) 1:1.9. Gonocoxites cylindrical (Figs 8, 17), approximately as long as the gonostyli from dorsal view. Gonostyli with circular base, almost straight, waving subapically (Fig. 18), pointed. Epandrium (Figs 7, 14) approximately quadrilateral, caudal half with numerous setae on both sides. Basal two apertures circular, divided, conspicuously bordered by sclerotized folds. Remainders of ventral epandrial plate V-shaped (Figs 7, 15), sclerotized laterally on both sides, with an approximately oval soft part inside, distally with two conspicuous external protrudent corners and near base of the epipropct with two miniature ones. Hypandrium narrow in connection with epandrium; however, the former broad, bar-shaped, with two swellings in the middle and a deep cleft between them (Figs 8, 16). Epiproct relatively small, with an almost semicircular caudal ending or fold, covered with short microsetae (Figs 7, 14–15). Hypoproct large, triangular or tongue-shaped, 0.4 times as long as the epandrial appendages, haired caudally (Figs 7, 14–15). Epandrial appendages (Figs 7, 14) about 1.8 times as long as the epandrium, curved slightly in the middle, and tenacula (numbers 9–12 are stable) restricted to clusters near the rounded apex, gradually becoming shorter towards top of epandrial appendages. Tenacula endings not fringed.
Female
Unknown.
Bionomics
