(43) Nemophora rubrofascia ( Christoph, 1882) View in CoL View at ENA

(Plate X-10)

Adela rubrofascia Christoph, 1882: 9 View in CoL (TL: Russia, Chingan and Wladiwostok); Rebel 1901: 245 (catalog).

Nemotois rubrofascia: Matsumura 1931: 1112 , fig. 2339 ( Japan and Taiwan); Matsumura 1932: 121, pl. 4, fig. 2 (list of Japan).

Nemophora rubrofascia: Hirowatari 2005b: 8 View in CoL ; Hirowatari 2013: 106, figs. 3-08-9,10; Umetsu 2014: 5, fig. 11 ( Japan, Akita Prefecture); Fukuda & Kanai 2016: 18 ( Japan, Kirishima Mt.).

Nemotois rubrifascia [sic!]: Meyrick 1912a: 8; Meyrick 1912b: 7; Meyrick 1914: 61 (Formosa [ Taiwan], Eastern Siberia).

Diagnosis. This species is easily distinguished from other species of this group by its unique metallic brass of forewing ground color with golden luster orange central fascia.

Specimens examined. Specimens from China were not available in this study.

Distribution. China (Taiwan); Russia, Japan.

Remarks. This species is also very similar to N. sakaii ( Matsumura, 1931) except for its related congeners, but it can be easily distinguished by the smooth basal antenna and asymmetrical margins of the forewing central fascia.

3.10 Nemophora divina species group

Nemophora divina View in CoL group ( Kozlov 1997e: 138)

Diagnosis. This species group can be characterized by the following features: the forewing base has a W-shaped light mark extending over 1/3 of the forewing length, or interrupted and formed into a small arcuate spot at the base and a line in the middle; the distal 1/3 of the forewing has pale light stripes that follow the direction of veins; the apical 1/3 of aedeagus is formed by the left wall only which forms a broad lobe; and the anellus with a pair of articulated carinae at the base of juxta.

Remarks. In addition to the above diagnosis, Kozlov (1997e) also characterized this species group by the basal 1/2 of female antennae with dense scale cover based on the adults of N. assamensis . However, we do not regard it as one of the diagnoses of this species group because this character is rather common in the family Adelidae , especially Nemophora .

Here, we place N. trimetrella Stringer, 1930 in the divina group because this species shares the above morphological diagnoses, especially in the male genitalia. Although the basal marking of the forewing does not form into W-shaped but a basal spot and a middle line, we consider this type to be an early evolutionary stage of the forewing pattern. In addition, we identified a new species belonging to this species group in Taiwan, China in this paper. Thus, the divina group consists of five species: N. divina ( Caradja, 1939) , N. assamensis Kozlov, 1997 , N. magnifica Kozlov, 1997 , N. trimetrella Stringer, 1930 , and N. songgangensis sp. nov. Therefore, all members of this species group are found in China.
