Quedius (Raphirus) filiolus View in CoL sp. n.
( Figs. 10–15 View FIGURES 1 – 10. 1 – 9 View FIGURES 11 – 22. 11 – 15 )
Type locality. People’s Republic of China: Yunnan: Nujiang Lisu Aut Pref. Salween side valley 5 km S Fugong, road SS 228, km 223.
Type material. Holotype (male), allotype (female): China: CHINA (Yunnan) Nujiang Lisu Aut Pref. Salween side valley 5 km S Fugong , road SS 228, km 223 (creek bank, litter sifted) 8.VI. 2007 D.W. Wrase [25] . Holotype in the Smetana collection, Ottawa, Canada, to be eventually deposited in the Museum d’histoire naturelle de Genève, Switzerland. Allotype in the Schülke collection, Berlin, Germany.
Description. In all character states quite similar to Q. muscicola and different mainly by the differently shaped aedoeagus.
M a l e. First four segments of front tarsus not appreciably different from those of Q. muscicola . Sternite 8 with two long setae on each side, apical margin with moderately wide and deep, obtuse medioapical emargination, small triangular area before emargination depressed and smooth ( Fig. 10 View FIGURES 1 – 10. 1 – 9 ). Genital segment with tergite 10 small, markedly narrowed toward narrowly subtruncate apex, with three long setae at apex, otherwise quite sparingly setose on middle portion ( Fig. 11 View FIGURES 11 – 22. 11 – 15 ). Aedoeagus ( Figs. 12–14 View FIGURES 11 – 22. 11 – 15 ) moderately large, narrow and elongate, median lobe vaguely, evenly narrowed anteriad into moderately long apical portion with subacute apex ( Figs. 12, 13 View FIGURES 11 – 22. 11 – 15 ), on face adjacent to paramere, when paramere removed, with fairly long medial carina ( Fig. 13 View FIGURES 11 – 22. 11 – 15 ) forming a distinct hook in lateral view. Paramere narrow, elongate, narrowly fusiform with narrowly arcuate apex not reaching apex of median lobe; four minute setae at apical margin, median setae somewhat longer than lateral ones, two similar setae at each lateral margin below apex; sensory peg setae on underside of paramere numerous, forming two long rows at each side of midline ( Fig. 14 View FIGURES 11 – 22. 11 – 15 ).
F e m a l e. First four segments of front tarsus simple, not dilated. Tergite 10 of genital segment small, markedly narrowed toward arcuate apex, with two long setae at apex and a few shorter setae in front of them, otherwise very sparingly setose ( Fig. 15 View FIGURES 11 – 22. 11 – 15 ). Female tergite 10 of Q. muscicola is narrower, and differently setose ( Figs. 9 View FIGURES 1 – 10. 1 – 9 , 15 View FIGURES 11 – 22. 11 – 15 ).
Length 4.8–4.9 mm
Geographical distribution. Quedius filiolus is at present known from the type locality in northwestern Yunnan at Salween river near Fugong.
Bionomics. The specimens of the original series were taken by sifting debris on a creek bank.
Recognition and comments. Quedius filiolus may be distinguished from Q. muscicola only by the markedly different aedoeagus ( Figs. 4 View FIGURES 1 – 10. 1 – 9 , 12 View FIGURES 11 – 22. 11 – 15 ) and tergite 10 of the female genital segment (see above). Sternite 9 of the male genital segment of the holotype was accidentally destroyed, therefore no description of it could be given.
Etymology. The specific epithet is the Latin noun filiolus , - i, m (a little son), a noun in apposition. It refers to the similarity of the species with Q. muscicola .
