【时代图集】巴布亚新几内亚又现新物种

A group of scientists discover 200 new species of frogs, rodents, and other critters

一个科学家团队在巴布亚新几内亚发现了200个新物种，其中包括蛙类、啮齿类和其他各种小动物。

Feather-tailed

羽尾毛皮兽

Not much is known of this furry critter, who was previously seen in 1985, but whose distinction from other species has only recently established. It still remains unnamed.

关于这种小巧的毛皮动物，我们知道得不多，人类上一次发现它还是在1985年，而且直到最近才确立了它和其他类似物种之间的区别。科学家们还没有给它正式命名。

Bright

鲜艳的蛙类

With a coloring pattern that varies considerably, these frogs are extremely difficult to spot in foliage in Papua New Guinea's Muller Range Mountains. Males make a soft ticking sound to attract mates nearby.

这些蛙类生活在巴布亚新几内亚的穆勒·兰格山（Muller Range Mountains）中，由于身上覆盖着变化多端的彩色图案，研究人员很难发现这种趴在叶片上的小生灵。这种雄性青蛙会通过产生柔和的滴答声来吸引附近的雌性前来交配。

Pink-eyed

粉眼螽斯

This group of leaf katydids are relatively unstudied and very little is known about them so far. Scientists believe that they feed on flowers found high in the trees of the forest.

人类较少研究这种叶片螽斯（leaf katydids），到目前为止对它们知之甚少。科学家们认为这种螽斯会爬到林木的高处寻找花朵为食。

First-of-its-Kind

墨绿螽斯

The dark emerald coloration of this new species of Mossula is unique and has never been observed in other katydids.

这只蝈蝈新品种身上的墨绿色非常独特，以前从未在螽斯家族中发现过这样的体征。

Loud and Clear

嗓门响亮的蛙类

Living 30 meters above the ground in the forest canopy, this large bright green frog was more often heard than seen. The males make a loud croaking sound that can be heard during the night.

这种体型硕大的亮绿色青蛙生活在距地面30米高的林冠之上，通常是只闻其声，不见其踪。其雄性蛙类会发出响亮的聒噪声，彻夜不息。

Furry Rodent

皮毛啮齿兽

Although this montane mouse resembles the prehensile-tailed tree mice of Papua New Guinea, it has been discovered to have no close relatives and represents a new genus.

尽管这种山鼠的外表与巴布亚新几内亚卷尾树鼠（prehensile-tailed tree mice）很相似，但实际上它与后者之间一点亲缘关系也没有，它代表了一种全新的物种。

Bugging Out

阿内蛛新品种

This spider is one in four new species of Anelosimus.

这种蜘蛛是阿内蛛属（Anelosimus）四个新品种中的一种。

Adaptable

适应性极强的蚂蚁

This ant species holds the record for the highest altitude for an ant in Papua New Guinea. They are able to live in both wet and cold conditions partly because they move slowly and have a slow metabolism that allows them to survive on a minimal food supply.

这种在巴布亚新几内亚发现的蚂蚁保持了蚂蚁界的生存记录：它们生活在海拔最高的地区。这种在潮湿阴冷条件下生存的能力部分取决于它们缓慢的行动能力和代谢能力，代谢缓慢意味着只需要很少的食物供应就可以存活。

Tree-huggers

奇特的蛙类

Found only in the highest elevations of the Nakanai Mountians, this species of frog is unlike many others in that they lay their eggs on land or in trees and hatch into frogs without ever becoming a tadpole.

科学家们只在最高的纳卡奈山（Nakanai Mountians）上发现了这种青蛙，它们和一般青蛙的不同之处在于，它们在陆地或树上产卵，并直接孵出小青蛙，无需经历蝌蚪阶段。

Big-headed

巨颚蚂蚁

The large major of this type of spiny ant, right, has a much larger head than that of the workers, left. Their powerful mandibles are used to crush food that workers bring back to the nest.

图中右边个头较大的刺蚁个体长着一个比左边工蚁要大得多的头部。它们强有力的颚部用来切碎食物，以便让工蚁搬回巢穴之中。
