038E5C07FFD44923FF1FFED762AB68AE.taxon	description	Description. Head. Antennae bipectinate in both sexes, with long rami in male and short rami in female. Frons white, not protruding. Labial palpi about 1 / 3 – 1 / 2 extending beyond frons; first segment white and third segment black in both sexes; second segment white ventrally and black dorsally in male, white or mixed with black dorsally in female. Vertex, patagium and tegula white. Thorax. Thorax with dorsal side white. Two black spots on prothorax and one black spot at middle of metathorax. Hind tibia not dilated, without hair-pencil, with two pairs of spurs in both sexes. Wing pattern. Forewing length: male 27 – 32 mm; female 30 – 32 mm. Both wings with apex rounded. Forewing with outer margin almost straight; anal angle gently rounded. Hindwing with outer margin rounded, slightly projecting on vein M 3 end. Wings whitish, semi-transparent. Costa of forewing and terminal half of both wings scattered with greyish black spots. Base of forewing tinged with pale yellow, a black spot present, without fovea; grey patches between veins forming an oblique middle band on forewing. Hindwing with basal half totally grey, margin of grey area almost parallel to outer margin. Fringes white. Underside identical to upperside. Abdomen. Abdomen with dorsal side whitish; a black spot present at middle of the first to the fifth segment respectively. Third sternite of male abdomen without setal comb. Eighth sternite unmodified. Male genitalia (Fig. 7). Uncus broad basally, narrow centrally, inflated apically with upper half narrower than lower half, slightly concave at apex. Socii absent. Gnathos with median process hook-like, bearing a cluster of small spines apically. Valva broad, blunt terminally, slightly concave on ventral margin near apex; densely setose on sacculus, apex, ventral margin and distal half of costa. Coremata present. Transtilla a pair of slightly sclerotized processes. Juxta pocket-like basally, with a pair of strongly sclerotized and symmetric furcae; furca gradually broadened to a distinctly hooked and tapering apex, small spines restricted to the apex of each arm. Aedeagus with anterior half broad, bifurcate anteriorly, posterior half columniform and narrow, middle part much narrower, without cornutus. Female genitalia (Figs 13 – 14). Papillae analis short and oval. Apophyses anteriores short, about 1 / 5 as long as apophyses posteriores. Sterigma undeveloped. Ductus bursae very narrow, as long as corpus bursae. Corpus bursae globular; signum an irregular, incomplete sclerite on a circular base (Fig. 13), or sometimes a semicircular base (Fig. 14).	en	Cui, Le, Xue, Dayong, Zhang, Chuntian, Han, Hongxiang (2014): A new species of the genus Genusa (Lepidoptera, Geometridae, Ennominae) from China.

038E5C07FFD44923FF1FFED762AB68AE.taxon	diagnosis	Diagnosis. On wing pattern, the new species is less marked than G. simplex (Fig. 6), and faintly marked as G. bigutta (Figs 3 – 4) and G. dohertyi (Fig. 5). In the male genitalia, the new species shares a similar valva and gnathos to the other three species in Genusa, but can be distinguished by the distinctive furca. The apex of each arm of the furca is strongly hooked and tapering in G. hollowayi, less hooked in G. bigutta (Fig. 8) and G. dohertyi (Fig. 9), rounded and blunt in G. simplex (Fig. 10). In addition, the spines on the furca are restricted to the apex in G. hollowayi, G. dohertyi and G. simplex, but spread down the shaft in G. bigutta. The uncus is also different, being apically inflated in G. hollowayi, but simply stick-like in G. bigutta, G. simplex, and slightly pointed in G. dohertyi. The species from Thailand and Burma (probably destituta), mentioned above, has arms of the furca relatively straight, and a narrower uncus (Fig. 11). In the species from Luzon (Fig. 12), the arms of the furca are hooked, but the shape of the uncus is much narrower.	en	Cui, Le, Xue, Dayong, Zhang, Chuntian, Han, Hongxiang (2014): A new species of the genus Genusa (Lepidoptera, Geometridae, Ennominae) from China.
