印度发现新品种蜉蝣

Scientists have discovered a new species of mayfly（蜉蝣） in the southern Western Ghats, a mountain range along the west coast of India. In fact, this is the first time that any mayfly belonging to the genus Labiobaetis has been collected in peninsular India. The new species, called Labiobaetis soldani, "is named in honor of Dr. T. Soldan for his substantial contribution to the understanding of the Ephemeroptera of Palaearctic and Oriental realms," according to the authors of a study that describes the new mayfly in the Journal of Insect Science.   The larvae¹（幼虫） have light-brown heads with light-yellow antennae²（天线，触须）, and they grow to be about 4-5 millimeters in length. Adults are also about five millimeters long, and the males and females both lack hind³ wings.   Labiobaetis soldani is closely related to Labiobaetis pulchellus, which has been described from Sri Lanka in the larval stage. However, it can be differentiated⁴ from all other Labiobaetis species described from the Oriental region by several morphological differences.
