Diagnosis
Helcystogramma flavistictum sp. nov. is similar to H. hassenzanensis Park et Hodges in the male genitalia. It can be separated from the latter by the labial palpus without long scales, the forewing with yellow dots along distal quarter of costal margin and termen; the gnathos slightly shorter than one-quarter length of valva, and the valva with dorsal and ventral margins parallel sided in the male genitalia.
Description
Adult ( Figure 9E View Figure 9 ). Wingspan 13.0–14.5 mm. Head dark grey, frons greyish-yellow to yellow. Antenna with scape dark brown on dorsal surface, white on ventral surface; flagellum greyish-yellow ringed with dark brown on dorsal surface, yellow on ventral surface. Labial palpus with second segment about twice length of diameter of eye, third segment about half length of second; first and second segments yellow and mottled dark brown on outer surface, yellowish-white on inner surface; third segment dark brown except yellow apically. Thorax dark grey to brown; mesothorax with greyishyellow hair pencil arising from anepisternum in male; tegula dark brown mixed with yellowish-brown. Forewing broadened gradually from base, termen truncate; ground colour yellowish-brown, with scattered dark brown scales; costal margin with basal three-quarters dark brown; black scale tufts at middle and end of cell as well as at middle of fold, round and margined with yellowish-white; apex dark brown; with yellow dots along distal quarter of costal margin and termen; fringe yellowish-brown mixed with greyish-brown, brown to dark brown at apex and at tornus. Hindwing and fringe grey. Legs greyish-brown to dark brown except tarsomeres yellow apically on outer surface; pale ochreous on inner surface. Abdomen dark brown, ventral surface with a longitudinal pale yellow fascia mesially.
Male genitalia
Uncus about one-fifth length of valva, with a small triangular process posteriorly, median width about half of basal width ( Figure 13C View Figure 13 ). Gnathos narrowed gradually from base, slightly shorter than one-quarter length of valva; culcitula semioval. Valva with dorsal and ventral margins almost parallel, bluntly rounded at apex, longer than tegumen–uncus complex; ventral free lobes nearly semicircular, with sparse long setae. Vinculum with lobes distinctly protruding on inner margin, distal two-fifths abruptly narrowed. Saccus bluntly rounded anteriorly. Aedeagus with basal two-thirds nearly parallel sided, short tubular distally. Seventh segment of abdomen with horn-shaped posterolateral processes; eighth tergite nearly quadrate ( Figure 10N View Figure 10 ).
Female
Unknown.
Distribution
China (Gansu, Henan, Shaanxi) .
Etymology
The specific name is derived from the Latin prefix flav -, meaning yellow, and Latin stictus, meaning spotted, referring to the yellow dots along distal one-quarter of costal margin and the termen on the forewing.
