Abdomen (including appendages) 30 mm. HW 48 mm.</p> <p>Differential diagnosis. Among the known species of the genus Ophiogomphus, the new species shares the following characters with O. longihamulus, O. minimus and O. sinicus, i.e. large pincer-like appendages with cerci curving posteroventrally and epiproct curving posterodorsally, with apex notched (Figs 10, 12).</p> <p>Ophiogomphus phantoani can be distinguished from the other congeners by the following characters: In the male, the cornua of glans has two long, acute widely separated, V-shaped flagella (Fig. 25), whereas they are relatively short, U-shaped flagella in O. longihamulus (Fig. 21), O. minimus (Fig. 23) and O. sinicus (Fig. 27); anterior hamulus of O. phantoani with well-developed developed posterior shoulder (Fig. 24) shoulder smaller in O. longihamulus (Fig. 20), O. minimus (Fig. 22) and O. sinicus (Fig. 26).</p> <p>In the female, the occiput of O. phantoani has a projection with two prominent dorsally microserrated branches (Fig. 32), more widely branched than in O. longihamulus (Fig. 28), O. minimus (Fig. 30) and O. sinicus (Fig. 34); the vulvar lamina of O. phantoani differs from the other species by a pointed tip (Fig. 33), which is incised apically but not widely opened as in the other species (Figs 29, 31, 35).</p> <p>Habitat and ecology. Ophiogomphus phantoani was found on a small, slowly running, densely vegetated stream (about 1–2 m wide) within pristine forest. The stream originates from a marsh with muddy bottom. The new species shares the same habitat with Coeliccia schorri Phan &amp; To, 2019; C. scutellum Laidlaw, 1932; Rhinocypha watsoni van Tol &amp; Rozeendal, 1995; Burmargiolestes sp.; Mnais mneme Ris, 1916; Orthetrum glaucum (Brauer, 1865); Anotogaster chaoi Zhou, 1998; Lamelligomphus camelus Martin, 1904 and Merogomphus pavici Martin, 1904.</p> <p>Distribution (Fig. 36).
