Agnoea (Tubuliferodes) digitiella Kim, 2020

( Figs 3 , 7 , 9 )

Agnoea digitiella Kim in Kim & Lee, 2020: 184 . Type locality: Korea, Chungbuk Prov., Goesan, Yeonpung .

Diagnosis. Kim & Lee (2020) distinguished this species from Agnoea josephinae , based on differences in the external appearance and the male genitalia, and the divergence in the COI sequences. The female genitalia of Agnoea digitiella differ from ones of A. josephinae in having the longer ductus bursae: ca. 5× longer than corpus bursae in A. digitiella but 4× in A. josephinae ( Fig. 9 vs. 10).

Description. Forewing length 6.3–7.9 mm (average 7.08 mm, n=10). External appearance of females same as that of males.

Female genitalia ( Fig. 9 ). Papillae anales small, oblique distally, narrowed apically, setose.Apophysis posterioris 2× longer than apophysis anterioris; apophysis anterioris curved at basal 1/3. Ostium bursae small. Ductus bursae ca. 5× longer than corpus bursae, narrow; antrum columnar, strongly sclerotized laterally, 1/4 as long as apophysis anterioris. Corpus bursae obovate, with signum at caudal 2/5; signum subrhomboidal, scobinate, less sclerotized longitudinally at middle.

Material examined. 4♂, Gyonggi Prov., Dongducheon, Mt. Soyosan , 13 VII 1998 (JC Sohn), [ GSN] SJC-770 ; 1♂, Gangwon Prov., Taebaeg, Mt. Maebongsan , 11 VII 1998 (JC Sohn), [ GSN] SJC-577 ; 3♂ 2♀, Gangwon Prov., Inje, Mt. Jeombongsan , 7 VII 2006 (JC Sohn), [ GSN] SJC-1199 (♀) ; 1♀ , Jeonnam Prov., Gurae, Sandong, Mt. Jirisan , Nogodan (N35°17′35.4″ E127°31′41.1″, alt. 1344 m), 20 VII 2004 (JC Sohn), [ GSN] SJC-547 .

Distribution. Korea (endemic).

Remarks. This species was described on the basis of only one male specimen. Female characters are described for the first time in the present study. Additional collecting localities are provided for Agnoea digitiella , expanding its distributional range.
