description: <i>Dicranomyia (Dicranomyia) globosa</i> sp. nov. urn:lsid:zoobank.org:act: 4AC026D2-6A76-463B-AD74-A3DBE6A918DF Figs 29–32 <b>Holotype</b> &amp;male;, Australia, New South Wales, Ku-Ring-Gai Chase, McCarrs Creek by Upper Gledhill Falls off McCarrs Creek Rd (33.663°S 151.250°E), 25 Sep 2017, Z. Billingham &amp; G. Theischinger, AM (K.394963). <b>Description</b> &amp;male; (&amp;female; unknown). <i>Head.</i> Antenna and palpus greyish brown. Antenna of moderate length, extending back to the prescutal pit, pedicel and flagellomeres 1–11 distinctly rounded, spherical, ultimate segment more conical. <i>Thorax</i> (Fig 29). Thoracic segments dorsally all dark brown, posterior areas of scutal lobes and scutellum a little lighter. Pleurites mostly uniform brown, propleuron and anepisternum a little darker. Coxae brownish, trochanters yellowish brown. Femora, tibiae, and first tarsal segment yellowish brown, darkening to greyish black at the tips, remaining tarsal segments greyish black. <i>Wing</i> (Fig. 30): brownish grey, extensively variegated with hyaline patches, veins brownish. Sc extending to nearly &amp;frac13; length of Rs, sc-r some distance before its tip in alignment with the fork of Rs, m-cu situated a little more than half its length before the base of the discal medial cell. Halter with stem deep greyish, knob lighter grey. <i>Abdomen:</i> greyish brown. <i>Terminalia</i> (Figs 31, 32). Hypopygium largely yellowish brown, lobes of inner gonostylus lighter yellowish white. T9 apically shallowly bilobed. Ventral lobe of gonocoxite rounded, about ½ the length of gonocoxite. Inner gonostylus approximately equal in length to gonocoxite, lobe rounded, globe-shaped, rostral prolongation of moderate length, lightly arched, tapering to a blunt tip, bearing two long spines at about &amp;frac23; length of the prolongation. Outer gonostylus a strongly arched rod, narrowing gradually to a sharp tip. Aedeagus a little shorter than gonocoxite, the tip faintly bilobed, parameres about ¾ the length of the aedeagus, lateral lobe low and rounded, mesal lobe gradually tapering to a sharp curved tip. <i>Dimensions.</i> Body length 6.8 mm, wing length 7.3 mm. <b>Etymology</b>. This species is named with reference to the globose lobe of the inner gonostylus. <b>Discussion</b>. <i>Dicranomyia (D.) globosa</i> is closely allied to numerous morphologically similar species around <i>D. (D.) saxatilis</i> Skuse, 1890 (see Theischinger 1994 for more details on these species). <i>Dicranomyia (D.) globosa</i> most closely resembles <i>D. (D.) saxatilis</i>, especially in the wing patterning, but is readily distinguished from <i>D. (D.) saxatilis</i> and other similar species by the long spines on the rostral prolongation of the outer gonostylus.
