In order to clear up confusion and explain problems related to coral taxonomy, such as drastic revisions in the taxonomic classification and Japanese names of the zooxanthellate scleractinian corals and problems in coral species identification, we have started a series of articles as “Topics on current taxonomy of corals”. To begin with, we will focus on the problem of “KUSHIHADA-MIDORIISHI / NANYOU-MIDORIISHI”, whose Japanese names are often confused. As a result of morphological, genetic and taxonomic analysis, all the Acropora hyacinthus-like populations in Japan should be treated as a “species complex” rather than a species unit, and should be referred to as the “Acropora hyacinthus species complex” (simplified version: Acropora hyacinthus complex) and as “KUSHIHADA-MIDORIISHI SHU-GUN” for Japanese name. However, as the “species complex” is generally not used in many cases, it is recommended that “Acropora hyacinthus” and “KUSHIHADAMIDORIISHI” are used instead of the “Acropora hyacinthus species complex” and “KUSHIHADA-MIDORIISHI SHU-GUN” as a coping strategy until the revision and nomenclature of all species of this species complex is completed.

ハナヤサイサンゴ科の3種のサンゴ，ハナヤサイサンゴ，トゲサンゴ，ショウガサンゴは，多くの海域でプラヌラ幼生を一年のうちの長い期間，月に1回の頻度で産出すること，産出の期間は低緯度ほど長く，高緯度になるにつれて短くなることが知られている（Harrison and Wallace 1990）。沖縄にもこれらのサンゴは生息し，しかも沖縄が分布の北限に近い（西平・Veron 1995）。沖縄県瀬底島（26°40′N, 127°50′E）において（1993年9月～1995年5月に3種を，1995年4月～1996年6月にショウガサンゴを飼育観察した結果，ハナヤサイサンゴは，自然温度（常温）下では，冬季（1～3月または2月～4月）には幼生産出がなく，その間に26℃に暖めると幼生産出し，温暖期でも22℃または20℃に冷やすと幼生産出がなくなることがわかった。20℃では，最初のひと月だけ幼生産出をおこない，以後死亡した。トゲサンゴとショウガサンゴは常温では，5月～9月及び10月の間に幼生を産出した。ショウガサンゴについては，1995年4月～1996年6月に，常温と定温（26℃）下で飼育観察した。常温では，6月～8月に幼生産出し，定温（26℃）ではそれ以外の季節でも幼生を産出した。この結果から3種のサンゴの幼生産出は水温に依存し，ハナヤサイサンゴの幼生産出の下限は20℃，トゲサンゴとショウガサンゴのそれは24℃と推測できる。これは，これらのサンゴの分布の北限とも関連する。西平・Veron（1995）によると，ハナヤサイサンゴの分布は串本（34°N, 年平均水温22.0℃），トゲサンゴは奄美大島（28°N, 24.5℃）（環境省・日本サンゴ礁学会 2004），ショウガサンゴは天草（32°N, 13-27℃）である。海水の温度は Yeemin et al. （1990）に拠った。ちなみに沖縄島は26°N, 25℃である。
花菜珊瑚科的三种珊瑚，花菜珊瑚，刺珊瑚，生姜珊瑚，在许多海域以一年中的较长时间，每月一次的频率出产幼体，出产时间越低纬度越长，众所周知，随着纬度越高纬度越短(Harrison and Wallace 1990)。冲绳也有这些珊瑚，而且冲绳接近分布的最北端(西平，Veron 1995)。1993年9月~ 1995年5月在冲绳县濑底岛(26°40′N, 127°50′E)饲养观察了3种珊瑚，1995年4月~ 1996年6月饲养观察了生姜珊瑚，结果发现花蔬菜珊瑚为:在自然温度(常温)下，冬季(1 ~ 3月或2月~ 4月)无幼体产出，在此期间将温度调至26℃就有幼体产出，即使在温暖期，温度调至22℃或20℃也无幼体产出。在20℃下，只有头一个月产幼，以后死亡。刺珊瑚和生姜珊瑚在常温下，5月~ 9月及10月间产幼。生姜珊瑚于1995年4月~ 1996年6月在常温和恒温(26℃)下进行饲养观察。常温下，6月~ 8月产幼仔，恒温(26℃)下，其他季节也产幼仔。由此可以推测，三种珊瑚的幼体产出取决于水温，花珊瑚幼体产出下限为20℃，刺珊瑚和生姜珊瑚为24℃。这也与这些珊瑚分布的北限有关。根据西平·Veron(1995)，花珊瑚的分布是串本(34°N，年平均水温22.0℃)，刺珊瑚是奄美大岛(28°N, 24.5℃)(环境省·日本珊瑚礁学会2004)，生姜珊瑚是天草(32°N, 13-27℃)。海水的温度依据Yeemin et al.(1990)。另外，冲绳岛为26°N, 25°c。
