Diagnosis. G. maritima is closely related to G. gaudialis Diakonoff &Arita, 1976 , by similar pattern of forewing, general morphology of the male genitalia, also by setaceous rounded lobes of postvaginal plate and large funnel-shaped antrum in the female genitalia. It can be differed by narrower forewing at whole, forewing with pale yellow transverse band at 1/5 of length, which narrower overall and especially constricted in dorsal half ( Fig. 4 View FIGURES 1–10 ). It differs by valva somewhat longer than aedeagus, vinculum with ventrolateral angles ventrally and relatively longer saccus, about half of aedeagus length in the male genitalia. Also, it is distinguished by setaceous lobes of postvaginal plate directed medially, antrum with large triangular notch on dorsal side and small thorns in its bottom arranged in ring with two lateral aggregations, narrow and long ductus bursae, approximately equal to corpus bursae in length and by corpus bursae more or less oval, without signa in the female genitalia ( Figs 31, 32 View FIGURES 28–32 ).

The related species G. gaudialis has broader forewing, which with yellow transverse band wider overall and not constricted in dorsal half. Its male genitalia with valva shorter than aedeagus, vinculum with rounded ventrolateral angles and relatively shorter saccus, 3.8 times shorter than aedeagus length in the male genitalia. Its female genitalia with lobes of postvaginal plate slightly flattened on apex and directed caudally, antrum without large notch on dorsal side, ductus bursae short, about 1/13 of corpus bursae length and corpus bursae elongated oval, with neck and two signa.

Adult, female. Wingspan 11.2 mm, forewing length 5 mm. The appearance of female corresponding to that of male described by Diakonoff (1979). The only differences in light yellow spot at 2/3 of dorsum: in female this spot Y-shaped, namely deeply emarginated similar to that in G. gaudialis , illustrated by Diakonoff (1986) ( Figs 4 View FIGURES 1–10 , 16 View FIGURES 11–17 ).

Female genitalia. Ovipositor relatively short, membrane between 9 th and 8 th abdominal segments about 1/3 of papillae anales length. Segment 8 th with sclerotised posterior margin. Apophysis posterioris slightly shorter than apophysis anterioris; each apophysis posterioris expanding into oval basal sclerotised plate distally, apophysis anterioris curved inwards in basal half. Setaceous lobes of postvaginal plate spaced and with rounded apex directed medially. Ostium large, rounded. Antrum sclerotised, funnel-shaped, with large triangular notch on dorsal side, and with ring of mainly singly located small thorns near bottom, some of which collected in 2 small lateral groups. Ductus bursae very thin, membranous, wrinkled in posterior part, almost equal to corpus bursae in length. Corpus bursae membranous, oval, without signa ( Figs 31, 32 View FIGURES 28–32 ).

Host plant. Unknown.
