Diagnosis. Neoacanthoneura subapicalis is very similar to N. apicalis in having the wing pattern with a triangular hyaline spot within the subbasal band and by the anterobasal margin of the apical spot perpendicular to the longitudinal veins rather than oblique and reaching at least R2+3 either as a dark streak or as the proximal margin of the whole spot, differing by the shape of the apical spot in the male, which is a C-shaped band, as in females of both species, whereas in N. apicalis it covers the entire apex of the wing. Both ♂ and females of N. subapicalis have wing pattern almost identical to that in females of N. apicalis , differing from females of that species by the anterior margin of the discal crossband covering the apical 0.55–0.7 of the pterostigma length and forming a short perpendicular shoulder at the anterobasal margin of the Γ-shaped discal crossband, whereas in N. apicalis it is conspicuously narrower, with the dark spot covering only apical 0.3–0.5 of cell sc.
Description. Male. Head yellow length: height: width ratio 1: 1.3: 1.5, with compound eye 1.4 times as high as long and frons 1.45 times as long as wide. Head setae and appendages as in N. apicalis . Thorax brown with partly yellow pleura, otherwise as in N. apicalis . Legs yellow with black setae and setulae, hind leg mostly brown.
Wing ( Fig. 39 View FIGURES 27 – 40 ) with pattern as described for N. apicalis female. Costal vein evenly arcuate, with ventral row of setulae not thicker than setulae of dorsal row. Pterostigma narrow, as long as costal cell. Vein R1 dorsally setulose along mostly whole its length, mostly subparallel to costa. Vein R2+3 slightly undulate. Vein M ratio m3: m2: m4 = 1: 8: 7.2; vein R4+5 bare. Wing length 2.3–3.2 mm.
Male abdomen and epandrium not dissected, externally as in N. apicalis .
Female similar to male, mid and hind legs mainly brown; wing ( Fig. 40 View FIGURES 27 – 40 ) as in female of N. apicalis , except pterostigma as long as costal cell, dark brown in apical 0.55–0.7 of length, with dark spot conspicuously wider than crossband posterior of it and forming Г-like shoulder; vein M ratio m3: m2: m4 = 1: 7–8: 5–6.5; vein R4+5 bare. Wing length 3.2–4.0 mm. Female terminalia not dissected.
Etymology. The name is from the Latin prefix sub - (below, near, almost) and apicalis , reflecting its similarity to N. apicalis new species.
