Common name. One-spotted delicate lacewing.
Type material. Holotype male INDIA: Kerala State: Palakkad District, Pudunagaram, elev. 104m, (coordinates: 10.6853, 76.6858), Bijoy. C., 20.XI.2020 (specimen Reg. No. ZSI/ WGRC / IRINV15593).
Diagnosis. Forewing and hind wing with single dark infuscate pustule; forewing with single row of cross-veins between subcostal veinlets in basal half of wing, absent in distal half wing; relatively few cross-veins in posterior margin of wing and never in multiple rows.
Description. Male: Forewing length: 29.5 mm; hind wing length: 29.9 mm. Overall colouration when live dark to pale green with dark red markings on head, and dark bands on abdomen (Fig. 1); wing membrane hyaline except for distinct round pustules and darkening of gradate-like cross-veins (Fig. 3). Head. Dark green, clypeus, frons and vertex dark red, green posteriorly; antennal scape dark red; pedicel yellow with small dark mark; flagellum uniform yellow, longer than wing. Thorax. Prothorax uniform light green; mesothorax and metathorax entirely dark green, unmarked; legs very pale whitish-green, unmarked, tarsi light brown; forewing hyaline, venation pale green, except for several irregular series dark cross-veins corresponding to gradates and distally on Psm, single round dark-brown pustule located on basal-most gradate series close to RP, single row of cross-veins joining subcostal veinlets in basal half of forewing, cross-veins lacking in distal half; single row of cross-veins connecting veinlets along entire posterior marginal area; hind wing similarly hyaline with pale green venation, cross-veins arranged in series in distal part of wing, single row of cross-veins connecting veinlets in posterior marginal area; single small round dark-brown pustule on basal gradate series close to RP. Abdomen. Uniform light to dark-green, brown band present on tergites 2–6; end of abdomen slightly bulbous. Terminalia (Fig. 5). Typical of apochrysines; not dissected.
Female: unknown.
Etymology. The species name is derived from the Latin— unus, one; maculatus, spot, stain, referring to the single pustule in each wing.
Comments. The male specimen was collected at lights in a village household. The surrounding habitat is semiclosed coconut plantation (Fig. 2) and is typical habitat for members of this subfamily. The single dark spot in each wing and the single row of cross-veins connecting subcostal veinlets in the basal half of the forewing is distinctive for this species. As noted by previous authors (Brooks & Barnard, 1990; Winterton & Brooks, 2002; Winterton & Gupta, 2020) the male genitalia are remarkably similar throughout the entire subfamily. Unfortunately, only the holotype of J. unimaculata sp. n. is known, and considering the expected lack of specific morphological characters therein, it was not dissected.
