摘要
记述采自中国四川省洞穴钩虾属1新种,奇异钩虾Gammarus praecipuus sp.nov.(图1～56)。新种与钩虾属其它物种的区别在于:眼睛缺失;第1小颚外叶具有31个齿,明显多于其它钩虾属物种的11个齿;第1尾肢内、外肢无侧刺或毛;第3尾肢内肢为外肢长的一半。
A new cave Gammarus species, Gammarus praecipuus sp. nov., from Sichuan, China, is described. This new species can be distinguished from other Gammarus species by eyes absent; the outer plate of maxilla 1 with 31 robust serrated apical spines, distinctly more than commonGammarus species with 11 spines ; both rami of uropod 1 bare; and inner ramus of uropod 3 reaching 0. 5 times the length of outer ramus. Type specimens are deposited in the Institute of Zoology, Chinese Academy of Sciences （ IZCAS）, Beijing.
