New species and new records of box crabs (Calappa) (Crustacea: Decapoda: Brachyura: Calappidae) from the Philippines
菲律賓的新種和新記錄種饅頭蟹屬（Calappa）螃蟹（甲殼綱：十足目：短尾類：饅頭蟹科）
摘要
The box crabs (Calappidae) of the Philippines are currently represented by only seven species. Seven more species are here added to the Philippine fauna, viz. C. capellonis, C. japonica, C. lophos, C. matsuzawa, C. undulata; two of which are desccribed as new, C. ocularia and C. liaoi. Calappa ocularia, new species, is similar to young C. bicornis but can easily be distinguished by its relatively flatter and proportionately broader carapace, more slender ambulatory meri, structure of the male abdomen and colour pattern. Calappa liaoi, new species, belongs to the C. gallus group of species, but can separated from taxa in this group by its carapace form, structure of the front and margins as well as colour in life.
並列摘要
菲律賓的饅頭蟹屬（Calappa）螃蟹原僅記錄有七種，本文另增加了七種，其中五種爲新記錄種，分別爲：C. capellonis，C. lophos，C. japonica，C. matsuzawa，和C. undulata；另有兩種爲新種，分別爲：C. ocularia和C. liaoi。Calappa ocularia和C. bicornis的幼蟹雖很類似，但不難區分。C. ocularia具有較平坦和較寬廣的背甲，以及較細長的步足長節；此外，兩種蟹的雄蟹的腹部結構也有不同，而身體的顏色也有差異。Calappa liaoi屬於C. gullus集團成員的一員，但從其背甲形態、額部和背甲側緣的結構，以及活體的顏色等方面，可將其區分出來。
