In thecourseof revising theAsian Ciidae, I found out an interestingspecies
belongingtothegenusCls,whichwascollectedbythelateDr.M. SAToinThailand.
Inthefollowinglines,thisnewspeciesisdescribedunderthenameofCissatoi,whose
specificepithet isgiveninhonorofhim.
Uptothepresent,twospecies,ClsaslatlcusLAWRENCE(1991)andRhopa1odontus
1awrenceiRuTA(2003),havebeenrecordedfromThailand,andthisnewspeciesseems
tobeathirdrepresentativeofthefamilyfromThailand.
The abbreviations employed in thispaper are thesameas thoseexplained in
previouspapersofmine.
Beforegoingfurther, IwishtoexpressmyheartythankstoDr.MasahiroSAKAI,

要 約
川那部 真: タイ国で発見されたッツキノコムシ科の1新種c、lssatoi (コウチュウ目ツッキノ
コムシ科ツツキノコムシ亜科). - 佐藤正孝博士により, 1987年にタイのPiTanで採集され
たッッキノコムシ属の1種を記載し, これを2006年8月9日に69歳で亡くなった先生に捧げ
て, C.satoiM. KAwANABEと命名した.
この新種は,日本に分布するニツコウッツキノコムシCisnikkoenslsNoBucH1,1960に似ている
が, 雄の頭部突起がより大きく顕著に反り返ることや, 前胸と上翅の幅が広いことなどによって
容易に区別できる.
