A revision of the Asian and European species in the subgenus Amiota Loew (Diptera, Drosophilidae) and the establishment of species-groups based on phylogenetic analysis Author Chen, Hong-Wei Author Toda, Masanori J. text Journal of Natural History 2001 2010-12-06 35 10 1517 1563 http://dx.doi.org/10.1080/002229301317067665 journal article 10.1080/002229301317067665 1464-5262 Amiota ( Amiota ) kamui sp. nov. (gure 15) Diagnosis . Gonopods separated medially, heavily sclerotized, each anteriorly forming sword-like, vertical process (gure 15C); parameres fused basally, slightly asymmetric: left one shorter than right one (gure 15D). Fig. 15. Amiota ( Amiota ) kamui sp. nov. , a paratype from Hokkaido , Japan : (A) epandrium and cercus; (B) surstylus and tenth sternite; (C) hypandrium and gonopo d (ventral view); (D) parameres and aedeagal apodeme (ventral view); (E) parameres and aedeagal apodeme (lateral view); (F) ejaculatory apodeme (scale-line =0.1 mm ) . Description. Male: Ocellar triangle and upper half of frontal vitta brownish black; lower half of frontal vitta and fronto-orbital plate dark brown. Antenna brown. Face dark brown on upper half. Gena pale brown. Wing with 24–26 minute, peg-like spinules on ventral surface of costal vein between R and R . 2+3 4 +5 Legs: Mid tarsus with a row of minute cuneiform setulae on posteroventral surfa ce. Male terminalia: Epandrium constricted more than one-half width mid-dorsally, with 17–18 setae near posterior to ventral margins (gure 15A). Surstylus lacking pubescence, not expanded at posteroventral corner, with about seven prensisetae increasing downward in size on distal margin, many relatively long setae on distal inner surface, and some small ones on ventral margin and outer mesal surface gure 15B). Tenth sternite entirely fused to surstyli laterally; lateral lobe-like process elliptical (gure 15B). Anteromedial portion of hypandrium slightly broadened gure 15C). Paramere lobe-shaped, weakly sclerotized, with about ve sensilla medially (gure 15D, E). Aedeagus lost or indistinguishably fused to paramere gure 15D, E). Ejaculatory apodeme: apical plate with four pits per side; stalk thick, about 2.5 times as long as plate (gure 15F).
