Abstract

The availability of many topotypic specimens of the deepsea shrimp Glyphocrangon stenolepis Chace, 1984 (Caridea: Glyphocrangonidae) recently collected off of Pratas Island (Dongsha), northern South China Sea, enabled us to establish the true identity of this species. Material previously identified as Glyphocrangon stenolepis from Taiwan and Japan is found to actually represent a species new to science. The new species, Glyphocrangon latens sp. nov., differs from G. stenolepis by the more clearly divided first (submedian) carinae on the carapace in females, better developed carinae on the pleon tergites, and high degree of genetic divergence inferred from the barcode segment of the mitochondrial COI gene.

台湾和日本的深海珠形虾的鉴定和对浅纹虾的描述

近年来在南海北部东沙岛收集到大量的深海对虾(glyphhocrangon stenolepis Chace, 1984)的形态标本，使我们得以确定该物种的真实身份。来自台湾和日本的一种先前被认定为窄纹草的材料被发现实际上代表了一种新的科学物种。新种Glyphocrangon latens sp. nov.与G. stenolepis的不同之处是，雌性甲壳上的第一(亚中位)隆突更清晰，多角体上的隆突更发达，线粒体COI基因的条形码片段推断出了高度的遗传差异。

期刊介绍： The Bulletin of Marine Science is a hybrid open access journal dedicated to the dissemination of research dealing with the waters of the world’s oceans. All aspects of marine science are treated by the Bulletin of Marine Science, including papers in marine biology, biological oceanography, fisheries, marine policy, applied marine physics, marine geology and geophysics, marine and atmospheric chemistry, meteorology, and physical oceanography. In most regular issues the Bulletin features separate sections on new taxa, coral reefs, and novel research gear, instrument, device, or system with potential to advance marine research (“Research Tools in Marine Science”). Additionally, the Bulletin publishes informative stand-alone artwork with accompany text in its section "Portraits of Marine Science."
