Furcilarnaca pulex ( Karny, 1928c) View in CoL

Figs. 63L View FIGURE 63 , 64E View FIGURE 64

Material examined. China, Shandong: Kiautschau * [near modern Qingdao], leg. Staudinger— 1 male (holotype) (ex coll. Karny, Wien NHMW) .

Description. Small species. Head: Face ovoid; fastigium verticis distinctly wider than scapus, separated by a weak suture (in specimen hardly visible) from fastigium frontis; ocelli indistinct; subocular furrow shallow.

Wings surpassing hind knees (in specimen tip broken, Fig. 63L View FIGURE 63 ). Tegmen: Radius with two branches, both forked near tip; MA free from base; MP absent or fused with CuA from base, CuA divides before mid-length into two veins, both simple ( Karny 1928c, tegmen broken); cubitus posterior undivided, free throughout; with 4 anal veins.

Coloration. General color uniformly light to medium brown. Face uniformly yellowish brown; eyes darker. Tegmen semi-transparent yellow; veins and veinlets yellow; hind wing semi-transparent white, main veins yellow, cross-veins light grey.

Male. Ninth abdominal tergite vaulted; hind margin rounded, entire, with a pair of small acute teeth just before margin. Tenth abdominal tergite narrow band-shaped, might be interrupted in middle; in central area, more widely separated than the teeth of ninth tergite with a pair of acute spines, each sitting on a swollen base. Subgenital plate badly damaged in type specimen: the plate is folded in about mid-length with the tip pointing anteriorly; the styli are inserted right and anteriorly-left of the fold; the apical part of the process of the subgenital plate is obviously broken or recurved a second time and lies probably inverted between the subgenital plate and the last tergites; it has the shape of a pair of dividing tubes with acute tips and the bases fused ( Fig. 64E View FIGURE 64 ).

Female unknown.

Measurements from Karny (1928c) (1 male).—body w/o wings: 9.6; pronotum: 2.3; tegmen: 10.8; hind femur: 6.8 mm.

Discussion. Karny (1928c) obviously overlooked that the subgenital plate of the type is folded and described the folding line between the styli as the end of the plate. He also did neither mention nor draw in his Fig. 9 View FIGURE 9 the large process of the subgenital plate or the pair of processes on the tenth tergite. This might have been due to the rather poor optic equipment during his time as compared to nowadays.

The male subgenital plate as figured in Li et al. (2015) looks quite different from the situation in the type at hand and from Karny's (1928) drawing. It was said that F. pulex occurs in Guizhou and Guangxi, but Karny's type is from Shandong. Thus the species listed by Li et al. (2015) probably represents a different, maybe unnamed species.

Remark: Kiautschau was a German overseas territory (trade station) before the first world war, roughly in the area of modern Qingdao [about 36°5''N 120°21'E].
