Apochrysa matsumurae Okamoto, 1912: 13 — Winterton & Brooks, 2002.

Nacaura matsumurae ( Okamoto, 1912) — Navás, 1913a; Kimmins, 1952; Kuwayama, 1962; Tsukaguchi, 1995; Brooks & Barnard, 1990.

Apochrysa minomoana Nakahara, 1915: 120 .

Nacaura minomoana ( Nakahara, 1915) —Navás, 1916.

Common name. ‘Matsumura’s delicate lacewing’.

Diagnosis. Forewing with a small irregular marking midway along inner gradate series (closer to ‘ psm’ than to RA; second dark spot (smaller) on distal RA-RP cross-vein at end of inner gradate series; hind wing with small mark on pterostigma and on distal RA-RP cross-vein; forewing with one distinct outer gradate series, inner gradate series obscured by numerous irregular cross-veins throughout RP branches, especially in basal half of wing; hind wing with two gradate series; forewing RA-RP cross-veins occasionally with interconnecting cross-veins; basal half of hind wing with irregular cross-veins connecting RP branches, fewer in number than in forewing; inner gradate series of hind wing broadly curved anteriorly at midpoint, running parallel to outer gradate series; end-twigging present along most of posterior margin of both wings.

Comments. The numerous irregular cross-veins in the forewing are diagnostic for this species. This gives the impression of only a single gradate series in the forewing as the inner gradate series is obscured by surrounding irregular cross-veins. Also diagnostic is the presence of occasional interlinking of RA-RP cross-veins, although these can be relatively few in number. Apochrysa matsumurae is widely distributed throughout Japan, China, Taiwan and India (Assam). Tsukaguchi (1995) described the larva for this species. The lectotype of A. matsumurae is housed in the Hokkaido University, Entomological Institute, while the location of the type of A. minimoana is unknown.
