Male: The specimen shows details of a nearly complete insect (Figs 1–5). A pair of forewings is almost symmetrically arranged, but hindwings are obscure. Head: Oviform in dorsal view, mouthparts opisthognathous or possibly hypognathous. Eyes large, widely separated. Between eyes, frons and clypeus well-developed. Proboscis ca. 6.8 mm long (proboscis length of paratype, 5.8 mm), straight, composed of indistinct labrum proximally and mostly labium, the latter with a distinct, fleshy pseudolabellum apically; mouth ellipsoidal and subterminally placed (Figs 7–8). Proboscis siphonate, stylets absent; covered with annulate dense hairs or microtrichia. Antennae distinctly longer than proboscis, flagellum multiarticulate, with annulate hairs. Thorax: Pronotum small; meso- and metanotum more or less similar to each other; both scutum and scutellum not discernible. Legs: Coxae smaller than those in typical scorpionflies. The legs entirely covered with annulate pubescence. Tarsi 5-segmented. The fore- and midlegs short, almost equal to antennae in length; their basitarsus distinctly shorter than remaining four segments combined in length. The hindlegs somewhat longer and slender, almost equal to forewing in length, with at least 1 apical spur; the basitarsus longest, almost equal to remaining four segments combined in length. All pretarsi with a pair of distinct claws, each developing a reduced and thickened pulvillus (Fig. 9). Wings: Forewing slender (length/width ratio about 3.5:1); apical margin obscure, probably rounded; membrane delicate. A humeral vein present at the base of costal area. Sc long, reaching wing margin almost at same level as the MA bifurcation, with three inclined anterior branches; Sc area with some circular pale spots. Pterostigma probably absent. Both Rs and MA with two endings at or near the apical wing margin; Rs forking later than MA; MP forking later than where MA originates from Rs, with 4 long branches. Thyridium
untraceable. Anal area broadened distinctly; A1 well developed. Forewing venational details is depicted in Fig. 6; hindwing untraceable. Abdomen: elongate, tapering apically, with 9 visible segments. Basitergum (T1) small and closely associated with the metathorax; segments 2–6 distinctly longer. Segments 7–8 more slender than 2–6 (Figs 2, 5); segments 9–11 obscure but enlarged, indicating male sex. Cerci unknown.
