Ancylosis larissae Bidzilya, Budashkin & Yepishin, 2019

( Figs 10–13 , 18 , 23 )

Ancylosis larissae Bidzilya, Budashkin & Yepishin, 2019: 449 ; Bidzilya et al., 2020: 468 .

Diagnosis. Ancylosis larissae is characterized by the elongate and apically curved gnathos ( Fig. 18 ) in the male genitalia; the broad elongate funnel-shaped antrum, the relatively short ductus bursae, and the large pear-shaped corpus bursae with numerous cone-shaped signa scattered medially in the female genitalia ( Fig. 23 ).

Variation. The ground color of the forewing is light brown, with or without pink fasciae ( Bidzilya et al. 2019). The forewings of our specimens vary from yellow mottled with or without pink scales ( Figs 10–13 ), yellow with or without a longitudinal pink band, or completely pink. However, the white or dirty white costal band is stable. In addition, the stability of the male and female genitalia features can also insure its one-species status ( Figs 18 , 23 ).
