Abstract

A unique type of mate guarding behavior is discovered in the araneid spider Caerostris sumatrana Strand, 1915: the male waits for the female's maturity while staying tied to the dorsal surface of her abdomen. The species is redescribed in detail. General appearance of the male and its fine structures are illustrated by scanning electron microscopy for the first time. Genital emasculation in the male of this species is reported for the first time.

摘要

1915年，在苏门答腊金蛛（Caerostris sumatrana Strand）中发现了一种独特的配偶守护行为：雄性蜘蛛会在雌性成熟前一直附着在其腹部背侧。对该物种进行了详细的重新描述。首次通过扫描电子显微镜展示了雄性蜘蛛的整体外观及其精细结构。首次报道了该物种雄性蜘蛛的生殖器阉割现象。
