Ordo: Coleoptera
Familia: Staphylinidae
Genus: Taiwanophodes
Name
Taiwanophodes minor Hlaváč, 2002 – Wikispecies link – Pensoft Profile
Type locality
China, Taiwan, Nantou.
Material examined
(2 ♂♂, 3 ♀♀). 2 ♂♂, labeled ‘CHINA: Hainan Prov. / Yinggeling, Nankai / Daoyin–Mohao / ca. 335 m, 15.iv.2010 / Mei-Ying Lin leg.’; 3 ♀♀, labeled ‘CHINA: Hainan Prov. / Wuzhishan Mt. / Guzhandao / ca. 640 m, 30.xi.2009 / 18.86657°N, 109.68285°E / Mei-Ying Lin leg.’.
Measurements
Male (female): BL 2.78–2.87 (2.68–2.74), HL 0.56–0.57 (0.57–0.58), HW 0.53–0.54 (0.52–0.54), PL 0.57–0.58 (0.58–0.60), PW 0.55–0.57 (0.53–0.58), EL 0.82–0.84 (0.67–0.69), EW 1.11–1.15 (1.06–0.10), AL 0.83–0.88 (0.86–0.87), AW 1.13–1.16 (1.16–1.22), length of aedeagus 0.50.
Diagnosis
Male. Reddish brown; medium-sized (Fig. 5); postocular margins rounded; each eye composed of about 40 facets; antennomeres X modified, ventrally concave at apical half (Fig. 6A); pronotum with angulate anterolateral margins; robust and short metaventral processes with hook-like apices (in lateral view) (Fig. 6B); protrochanters spinose ventrally; protibiae with small apical spur (Fig. 6D); tarsomeres II extending to mid-length of tarsomeres III (Figs 6D–F); aedeagus asymmetric, median lobe elongate, parameres largely reduced (Figs 6G–I).
Female. Similar to male in general; each eye composed of about 30 facets; lacking antennal modification; lacking metaventral process; apices of protibiae simple.
Distribution
South China: Taiwan, Hainan (New Province Record).
Comparative notes
Readily distinguished from the only other congener Taiwanophodes magnus Bekchiev, 2010 by the smaller size, antennomeres X being less modified, pronotum being angularly expanded anterolaterally, profemora and protibiae being simple, different conformation of the metaventral processes, and aedeagus with more elongate median lobe and reduced parameres.
Comments
Taiwanophodes minor was originally described from central Taiwan (Hlaváč, 2002). It is somewhat surprising that this species also occurs in the Hainan Island, suggesting geographic affinities between the two islands.
