Abstract:
UNASSIGNED: The Laophontidae is a very large and diverse family containing more than 320 species and 74 genera in the Harpacticoida. According to records published until recently, 25 species of 12 genera of Laophontidae were reported to appear in Korean waters. The most common laophontid species in Korean waters is Paralaophontecongenera (Sars, 1908). During research on the meiobenthic community in the subtidal zone near the Korean coast in the East Sea, we found an undescribed genus of the Laophontidae family. The character traits of this undescribed specimen of the Laophontidae family do not match any existing genus.
UNASSIGNED: Herein, a new genus of the interstitial marine benthic copepods family Laophontidae T. Scott, 1905 is described from the subtidal zone near Hupo Harbour on the east coast of Korea. This genus was named Strictlaophonte gen. nov. and has been classified into the family Laophontidae. This was based on the presence of seven segmented female antennules, reduced antennary exopod, first endopodal segments having no inner setae from the second leg to the fourth leg and P5 with a distinct exopod that is not fused at the basis. The distinguishing features of Strictlaophonte gen. nov. are P5 exopod having only four setae, the P1 exopod having two segments and the antenna exopod having four setae. In particular, this new genus has unique characteristics in that the caudal rami are very tightly attached to each other.
摘要:
Laophontidae是一个非常大且多样化的家族,在Harpacticoida中包含320多个物种和74属。根据直到最近公布的记录,据报道,朝鲜水域出现了12属Laophontidae的25种。韩国水域中最常见的laophontid物种是Paralaophontecongenea(Sars,1908).在对东海朝鲜海岸附近潮下带的中底栖群落的研究中,我们发现了Laophontidae家族的一个未描述的属。Laophontidae家族的这种未描述标本的特征与任何现有属都不匹配。
这里,间质海洋底栖co足类科LaophontidaeT.Scott的一个新属,1905是从韩国东海岸Hupo港口附近的潮下带描述的。该属被命名为Strictlaophontegen。11月。并被归类为Laophontidae家族。这是基于七个分段的雌性触角的存在,减少了天线外脚架,从第二支腿到第四支腿没有内刚毛的第一内足节段和具有在基部不融合的不同外足的P5。Strictlaophontegen的显着特征。11月。P5外足只有四个刚毛,P1外脚架具有两个区段并且天线外脚架具有四个刚毛。特别是,这个新属具有独特的特征,因为尾rami彼此紧密相连。
