Abstract

Two new species of Petrobunus Sharma Giribet, 2011, (Petrobunidae) are described: P. chongqing sp. nov. (♀♂) and P. hebei sp. nov. (♀♂). Petrobunus chongqing sp. nov. is similar to P. spinifer Sharma Giribet, 2011, in having two large spines on the male sternite 7. However, the new species can be distinguished from P. spinifer by the absence of a ventral tubercle on the male femur IV, as well as the presence of three pairs of enlarged tubercles on the lateral margin of area V and free tergites I-II. Petrobunus hebei sp. nov. and P. torosus Sharma Giribet, 2011 closely resemble each other. They are distinguished by the morphology of the ocularium, in that P. torosus has a median tubercle whereas the ocularium of P. hebei sp. nov. is unarmed. The discovery and descriptions of these species greatly expand the known range of the genus Petrobunus.

摘要

描述了2011年的Petrobunus Sharma Giribet属（Petrobunidae科）的两个新物种：重庆Petrobunus（P. chongqing）新种（♀♂）和河北Petrobunus（P. hebei）新种（♀♂）。重庆Petrobunus新种在雄性第7腹节上有两个大刺，这一点与2011年的具刺Petrobunus（P. spinifer）相似。然而，新物种与具刺Petrobunus的区别在于雄性第四股骨上没有腹侧瘤，以及在区域V的侧缘和游离背板I-II上有三对扩大的瘤。河北Petrobunus新种和2011年的粗壮Petrobunus（P. torosus）彼此非常相似。它们的区别在于眼瘤的形态，粗壮Petrobunus有一个中瘤，而河北Petrobunus新种的眼瘤无武装。这些物种的发现和描述极大地扩展了Petrobunus属的已知范围。
