Neosclerus atsushii SHIBATA, 1992 ( Figs 125-133)

Neosclerus atsushii SHIBATA, 1992: 184 ff.

Type material examined:

Paratypes: 1 , 1 : "( Lushan Wenchuan ), Nantou Hsien, Taiwan (1200 m), July 28th, 1983, Y. Shibata leg. / [Paratype] Neosclerus atsushii , , Y. Shibata 1992." (cShi, cAss) .

Comment:

The original description is based on a male holotype, a female allotype, and seven paratypes from " Lushan Wenchuan , about 1,200 alt., Nantou Hsien, Taiwan " (SHIBATASHIBATA 1992) .

Redescription:

Body length 3.5-4.0 mm. Habitus and forebody as in Figs 125-126. External characters as in N .. bifidus .

: posterior margin of sternite VII distinctly concave in the middle, near this concavity with cluster of numerous slender setae ( Fig. 127); sternite VIII anteriorly with relatively broad and short carina with several setae, posteriorly extending into a short bifid process, posterior excision not distinctly V-shaped, its depth approximately 1/5 the length of sternite ( Figs 128-130); aedeagus with ventral process similar to that of N .. bifidus , but apical portion in lateral view shorter and broader, and in ventral view more slender ( Figs 131-133).

Comparative notes:

The similar external characters and the similarly derived shape of the ventral process of the aedeagus suggest that N .. atsushiiatsushii is the adelphotaxon of N .. bifidus , from which it is distinguished by the shape and chaetotaxy of the anterior carina of the male sternite VIII (broader, shorter, presence of several setae in the middle, posteriorly less strongly extended), the less deep posterior excision of the male sternite VIII, and the slightly differently shaped apex of the ventral process of the aedeagus ( Figs 133-134).

Distribution and bionomics:

This species is known only from the type locality in Nantou Hsien, Taiwan, where the type specimens were collected at an altitude of 1200 m (SHIBATASHIBATA 1992) .
