description: Paramorganiella adventurosa Tonnoir 1929   
Tonnoir 1929: 606.  
 Remarks on identification. We identified our specimens on the basis of the male description by Tonnoir (1929), which includes a figure of the unmistakable mouthparts (text fig. 5). It is important to note that the wing figures 14 and 15 in Tonnoir´s paper were mistakenly inverted, and the Paramorganiella wing is actually shown in fig. 14, not 15. We did not study the holotype of P. adventurosa, which according to Bugledich (1999) is allocated in the Australian National Insect Collection, Canberra.   
 Male redescription. Head. Fourth flagellomere 1.8 times as long as wide. Clypeus elongate ovate, on basal half convex, with large setae, on distal half clearly concave, basket-shaped, with sparse fine setae (Fig. 2A). Surface of stipes with microtrichia arranged in lines, lateral setae; stipites fused anteriorly, forming Ushape, with sclerotized longitudinal axis. Lacinia, if correctly identified, present as sclerotized rib between stipes and base of second maxillary palpus segment (Fig. 4C). Palpus 5-segmented, segments 1–4 more or less strongly modified (Fig. 2C–E, 4C). Segment 1 fused medially with proboscis, large setae dorsally, subtriangular process apically to receive segment 2. Segment 2 swollen, largest of all, short setae dorsomedially, 6–7 sensilla coeloconica arranged in line ventromedially. Segment 3 short, inserted subapically on segment 2, 2 short stiff setae medially and long sclerotized process dorsally which bears 4–5 setulae apically, otherwise bare, without specialized sensilla. Segment 4 with 6–7 long stiff setae medially, 2 sclerotized processes, dorsal process broad, with 3–4 large setae, otherwise bare, margin occasionally irregularly serrate, lateral process narrow, dagger-shaped, bare. Segment 5 elongate, slightly club-shaped, 10– 12 stiff setae on apical half. Prementum very large, bilobed, lobes separate medially, densely microtrichose (Fig. 2B). Premental apodemes touching each other medially, forming X-shape. Basal segment of labellum asetose, apical segment setose (Fig. 4C).   
 Wing (Fig. 3). Length 2.3–2.8 mm. Slightly fumose in the distal region of R1 and R5. Halter whitish.   
 Legs. Tarsomere 4 of fore leg with crest of 3–4 short stiff setae ventrolaterally, tarsomere 5 with 2 setae of same kind but shorter, both groups of setae together forming clamping apparatus when tarsomeres are folded (Fig. 3B).   
 Terminalia. St 9 fused with gonocoxites, identifiable as sclerotized rib close to basal margin of gonocoxites (Fig. 4B). Tg 9 subrectangular, densely setose, apical margin slightly emarginate (Fig. 4B). Gonocoxites largely fused ventrally, on apical half separated by narrow cleft, short ventral and longer lateral setae, on apical margin 2 pairs of processes, lateral pair hook-like, medial pair short subtriangular (Fig. 4B). PostGA convoluted, fringed apically, with finger-like medial process tipped by one thick macroseta (Fig. 4A). AntGA very large, rounded (Fig. 4A). Gonostylus directed medially, slender, tapered towards apex, with a few short setae including 4 strong, stiff setae in line on ventral margin, and 2 subapical setulae (Fig. 4A). Parameres fused to form short tegmen with deeply notched apical margin, strongly sclerotized, parameral apodemes large, rounded (Fig. 4A). Hypoproct slightly shorter than cerci (Fig. 4B), separate apicomedially, with dense large microtrichia and a few apical setae. Cerci separate medially (Fig. 4B), dense microtrichia, setae of various sizes including several thick stiff setae pointing ventrally.   
 Female description. Head. Antenna much shorter than in male, fourth flagellomere 1.4 times as long as wide. Clypeus convex (Fig. 3A). Lacinia style-like (Fig. 3A). Palpus segment 2 thicker than other segments, segment 3 without sensilla cochleariformis (Fig. 3A), which are usually present in Mycetophilidae (Søli 1997).   
 Thorax. Shallower than in male. Wing. Length 2.8 mm. As the male (Fig. 3C).   
 Preabdomen. St 4–7 with numerous short stiff blunt-tipped setae among ordinary setae. Terminalia. In accordance with the mycetophilid ground pattern (cf. Søli 1997: fig. 37B). Disticercus somewhat shorter than basicercus.
