附录1 —— 莱氏假虾(*P. licenti* Van Straelen, 1928)描述性统计表 ### 头胸部(cephalothorax)轮廓 #### 背腹向观 轮廓呈梨形,头部区域向前渐窄,鳃区较为宽阔;侧缘略呈弧形,长大于宽(依保存状态不同,最长可达宽的1.9倍);眼切迹(ocular incision)向前开口,后缘中部略凹、平直。 观测标本:NIGP-DYH-4、NIGP-DYH-6、NIGP-Shen-12、NIGP-Shen-16、NIGP-Shen-17、NIGP-Shen-18a、b、NIGP-Shen-19、NIGP-Shen-23、NIGP-Shen-35、NIGP-Shen-40、NIGP-Shen-42、NIGP-Shen-71、NIGP-Shen-F、NIGP-Shen-RT145、NIGP-126337、NIGP-126342、NIGP-126347、NIGP-126353、sp1、sp2、sp4、sp5、sp7-10、sp11、sp16-17、sp20、sp23、sp24-25、sp26-27、sp29、sp31、Tohoku-U-57254 #### 侧视(lateral view) 大致呈亚矩形,背缘平直,腹缘弧形,后缘呈波状,前缘被眼切迹和触角切迹截断。 观测标本:NIGP-DYH-5、NIGP-Shen-1-3、NIGP-Shen-5-6、NIGP-Shen-11、NIGP-Shen-33-34、NIGP-Shen-50-51、NIGP-Shen-62、NIGP-Shen-68、NIGP-Shen-b-c、NIGP-Shen-GM1、NIGP-126340、NIGP-126366、sp22、Tohoku-U-57272 ### 比例 宽略大于高(高/宽);除NIGP-Shen-20与NIGP-Shen-56外的所有标本,该比例基于更多背腹向压扁而非侧视的标本样本量。 ### 额剑(rostrum) 由基段与端段组成;基段较宽,长度约为额剑总长(从尖端至眼切迹)的一半略少,向远端渐窄,两侧具一对侧刺,构成眶上脊(supraorbital carina)的尖端;端段狭窄呈刀状,边缘具细脊;轴区具凹陷/宽沟。 观测标本:NIGP-Shen-1-2、NIGP-Shen-12、NIGP-Shen-32、NIGP-Shen-39、NIGP-Shen-42、NIGP-Shen-a、NIGP-Shen-GM1、NIGP-RT132、NIGP-RT143、NIGPAS-126338-126339、NIGP-126342-126343、NIGP-126346-126347、sp2、sp6、sp8、sp11、sp18、sp24-25 ### 背缘 平直,具浅沟。 观测标本:NIGP-DYH-5、NIGP-Shen-1-3、NIGP-Shen-5-6、NIGP-Shen-11、NIGP-Shen-19-20、NIGP-Shen-33-34、NIGP-Shen-50-51、NIGP-Shen-62、NIGP-Shen-68、NIGP-Shen-b-c、NIGP-Shen-GM1、NIGP-126340、NIGP-126366、sp22、Tohoku-U-57272 ### 眼切迹(ocular incision) 浅短且钝圆。 观测标本:NIGP-Shen-19-20、NIGP-Shen-33-34、NIGP-Shen-50-51、NIGP-Shen-62 ### 触角切迹(antennal incision) 短于且浅于眼切迹。 观测标本:NIGP-Shen-68、NIGP-Shen-b-c ### 鳃甲刺(pterygostomian spine) 无鳃甲刺,鳃甲角(pterygostomian angle)略圆。 观测标本:NIGP-Shen-GM1、NIGP-126340、NIGP-126366、sp22、Tohoku-U-57272 ### 腹缘 弧形,具沟,与后缘的腹/鳃区无缝衔接。 ### 后缘(具关节面) 平直,具浅沟。 ### 后缘(无关节面) 弧形,具沟。 ### 鳃区(branchial area) 原文未提供额外描述
