External characters. Wing span 12–14mm. Frons, labial palpi, maxillary palpi and antennae orange-brown. Thorax and abdomen pale yellow; legs yellow-brown. Forewing silvery white; medial line fuscous, from middle of costa to discocellulares, then bent to inner margin; submarginal line fuscous, from costa to vein M1 then bent inwards to anal angle; marginal area suffused with orange-yellow longitudinal fasciae along the veins and a black spot between M3 and Cu1; a black marginal line from apex to middle of outer margin; cilia silvery white, suffused with dark brown. Hindwing white; cilia white, male with a tuft of yellow-brown cilia at anal angle.
Male genitalia. Uncus strong, the apex pointed, ventral with a tuft of thick setae; gnathos tapering pointed, slightly curved to dorsal; tegumen triangular, elongate; valva with basal broad and apical contracted, costal arm longer than valva, apart from valva, the apex pointed, sacculus strongly sclerotized; juxta long oval-like, with two lobe-like processes at apex; aedeagus round at apex, with four spine-like cornuti.
Female genitalia. Anal papillae weakly fused, with dense setae; apophysis posterioris little shorter than apophysis anterioris; ostium bursae bifid, slightly sclerotized; ductus bursae long, swollen and sclerotized at middle; corpus bursae elliptic, with two spine-like signa.

Distribution. China (Guangdong, Guangxi).
Remarks. This species is similar to G. bilineata sp. nov., but can be distinguished by following: in external characters, forewing of this species with one submarginal line and without the fuscous spot at the lower angle of cell, while the latter with two submarginal lines and with a fuscous spot at the lower angle of cell; in male genitalia, this species with 4 spine-like cornuti in aedeagus while a row of spine-like cornuti in latter; in female genitalia, this species with the bifid ostium bursae different with G. bilineata.
Etymology. The name is derived from the Latin “ quadr ” and “ spinula ”, corresponding to the 4 spine-like cornuti in aedeagus.
