Pseudaulacaspis kiushiuensis (Kuwana, 1909) (Diaspididae: Pseudaulacaspis)

Nomenclatural History

• Chionaspis kinshinensis Kuwana 1909: 155. Type data: JAPAN: Kyushu, Fukuoka, on Quercus sp., 1907, by S. Kuwana. Syntypes, female, Type depository: Yokohama: Yokohama Plant Quarantine Service Station, Honshu, Japan; accepted valid name Notes: This spelling was corrected by Kuwana (1928) to kiushiuensis and since it has been the prevailing spelling (see ICZN (1999) article 33.3.1) it is accepted as a justified emendation.

• Chionaspis kinoshinensis Kuwana, 1909; Kuwana 1909: 158. misspelling of species epithet
• Phenacaspis kinshinensis (Kuwana, 1909); MacGillivray 1921: 347. change of combination
• Chionaspis kiushiuensis Kuwana, 1909; Kuwana 1928: 12. emendation that is justified (discovered by MillerBeGi2002, ). Notes: Kuwana, in the original description used the spelling kinshinensis and kinoshinensis. In 1928, he emended his original spelling to kiushiuensis. Although this could be considered an unjustified emendation because it wasn't one of the original spelling, according to ICZN article 33.3.1 when an incorrect subsequent spelling is in prevailing usage it is deemed to be a correct original spelling. Prevailing usage definitely is kiushiuensis.
• Chionaspis kiushinensis Kuwana, 1909; Kuwana 1928: 13. misspelling of species epithet

Remarks

• Systematics: Pseudaulacaspis kinshinensis is allied to Chionaspis colemani (=Unachionaspis signata) in the shape, color and texture of the scale, but is distinguished by the structure of the last abdominal segment (Kuwana, 1909).
• Structure: Adult female with dorsal macroducts in single or irregularly double segmental rows; submedian macroducts absent or few present on 2nd abdominal segment, always present on 3rd to 5th, absent on 6th. Median lobes comparatively very large, slightly divergent, minutely serrate, rounded apically, with a pair of setae between them, the basal zygosis scarcely protruding anteriorly. 2nd lobes very small, bilobulate. 3rd lobes represented by low processes (Takagi, 1961). Adult female cover white, oyster-shell shaped; shed skins marginal, yellow to brown. Male cover smaller, felted, white, elongate, with slight median carina; shed skin yellowish (Kuwana 1917).
• General Remarks: Detailed descriptions and illustrations by Kuwana (1928) and (Takagi, 1961).
