Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335); earina: Name from Latinized form of the Greek adjective 'earinos' meaning 'the color of spring', which is green; referring to the pale green color of this species in life.

生態學
海洋 礁區魚類; 深度上下限 60 - 116 m (Ref. 59379). 熱帶; 9°N - 21°S, 129°E - 178°W
Western Pacific: from Puluwat westward to Palau; south to Papua New Guinea, Vanuatu and Fiji; also Indonesia. It was not observed at Rarotonga (Cook Islands), Kiritimati (Line Islands), nor American Samoa during brief surveys of deep reefs at these localities.
西太平洋: 從 Puluwat 向西到帛琉; 南至巴布亞新幾內亞，萬那度與斐濟; 也印尼。 它是在這些地點在深礁的簡短調查的時候在拉羅東加 (科克群島) ， Kiritimati(列島群島) 也不美屬薩摩亞群島沒有被觀察到。

Maturity: Lm ? range ? - ? cm
Max length : 6.6 cm SL 雄魚/尚未辨別雌雄; (Ref. 59379)
背棘 (總數) : 12 - 13; 背的軟條 (總數) : 11 - 12; 臀棘: 2; 臀鰭軟條: 12. This species is distinguished by the following characters: Dorsal rays XII-XIII, 11-12, usually XIII, 12; anal rays II, 12; pectoral rays 17-18, usually 18; spiniform caudal rays 3; tubed lateral-line scales 13-15, rarely 16; gill rakers 6-8 + 18-21 (total 26-28, rarely 25); body depth 1.65-1.9 in SL. The color when fresh is pale slate blue (bright pale green in life) with a white spot (sometimes two white spots) roughly the size of a scale mid-laterally on the body; malachite green area above orbit and in inter-orbital space and nape; the dorsal and anal fins with bright distal border of pale turquoise blue (Ref. 59379).
這種被藉著下列的特徵區別: 背鰭鰭條 12 XIII 的, 11-12, 通常 XIII, 12; 臀鰭鰭條 2,12; 胸鰭鰭條 17-18, 通常 18; spiniform 尾部的鰭條 3; 管狀的側線鱗片 13-15, 很少地 16; 鰓耙 6-8+18-21;(總數 26-28, 很少地 25) 體高 1.65-1.9 分之一標準體長。 顏色新鮮時是灰白的暗藍灰色藍色 (明亮的灰綠色活著時) 在身體上側面中央地概略地具有一個白色的斑點 (有時二個白色的斑點) 鱗片的大小; 在眼窩上面的孔雀石綠色區域與在眼窩之間的空間與後頸; 背鰭與臀鰭有亮的灰白藍綠色的藍色的末梢部邊緣。 (參考文獻 59379)
Adults inhabit steep outer reef slopes and drop-offs with rocky outcrops and small caves and holes, often in association with limestone talus; usually observed in pairs or small groups, feeding low in the water column, and are generally abundant where they are found (Ref. 59379). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
這種居住於陡峭的外礁斜坡，而且海峭壁有岩石的露頭與小的洞穴和孔洞, 常見於鄰近石灰石碎石堆中; 通常觀察成對或形成小群魚群, 進食低的在水團, 而且通常豐富在那裡它被發現.(參考文獻 59379)
