Abstract

The first, apparently westernmost indigenous representatives of Haplodesmidae are reported, from the Himalayas of Nepal and India. Both new species belong to a new genus, Koponenius gen. nov., with K. unicornis sp. nov., the type species from Darjeeling District, NE India, and K. biramus sp. nov., from Nepal. The new genus is superficially very similar to Prosopodesmus Silvestri, 1910, most species of which seem to be native to tropical Australia, partly also to southern Japan. However, Koponenius gen. nov. is easily distinguished in showing only 19 body segments, a special ozopore formula (5, 7-18), 4 transverse rows of setigerous isostictic tubercles per postcollum metatergum, and a clearly helicoid, twisted prefemoral portion of the gonopod so that the seminal groove runs mostly laterally, not mesally.

摘要

首次报道了来自尼泊尔和印度喜马拉雅地区的单带马陆科最西部的本土代表物种。这两个新物种都属于一个新属，即科波嫩马陆属（Koponenius gen. nov.），其中独角兽科波嫩马陆（K. unicornis sp. nov.）为模式种，来自印度东北部大吉岭地区，而双枝科波嫩马陆（K. biramus sp. nov.）来自尼泊尔。这个新属在外观上与1910年的西尔韦斯特里马陆属（Prosopodesmus）非常相似，该属的大多数物种似乎原产于热带澳大利亚，部分也分布于日本南部。然而，科波嫩马陆属很容易区分，它只有19个身体节段，有特殊的臭腺孔公式（5, 7 - 18），每个颈后后胸背板有4排横向的刚毛等节瘤，并且雄肢的股节前部明显呈螺旋状扭曲，使得精液沟大多横向延伸，而非向中线延伸。
