Concavocorona abbreviata ( Jacobi, 1944) , n. comb.

( Figs 11–20 )

Cunedda abbreviata Jacobi 1944: 51 [n.sp.]; Metcalf 1963, 6(6): 51

Description. Body length (including forewing): ♂, 7.5–8.0mm. The transverse beige patch ( Fig. 14 ) on frontoclypeus small, taking up less than 1/4 area of frontoclypeus, and no spot is enclosed.

Ventral process of pygofer ( Figs 15, 17 ) straight. Aedeagal ventral process in lateral view approximately rectangular ( Fig. 18 ). Style ( Fig. 16 ), apodeme apex acutely curved laterally in ventral view, the apophysis is of uniform width only in middle region and distally it gradually narrows. Other characteristics as shown in Figs 11–20 .

Material. 1♂ (Paratype, NMS), China, Fujian Prov., Wuyi Shan (mts.), kuatun, 2300m, 117° 40' 00" E / 27° 40' 00" N, 19. IV.1938, coll. J. Klapperich. (The original label is sample and in German, this data refer to Lampe et al. (2010), and I conjecture that kuatun should be Gua dun (117° 39' 05" E / 27° 43' 51" N).)

Remarks. The crown ( Fig. 13 ) of this species is strongly concave, which may be the reason Jacobi (1944) placed it in the genus Cunedda Distant, 1918 . However, the lamellate, elevated median longitudinal carina makes the crown concave laterally in Cunedda , but the median longitudinal carina of this species is not lamellate and elevated and the entire disc of the crown is concave; in addition, the crown is shorter than the distance between the eyes, but it is longer in Cunedda Distant. Also , the male pygofer ( Figs 15, 17 ) of this species has a slender ventral process, which is absent in Cunedda . Therefore, the species is here transferred to Concavocorona gen. n.
