摘　　要：2018年8月下旬,在河南省南阳市桐柏山采集到11号石龙子科(Scincidae)蜥蜴标本。经形态比较鉴定,该批标本均为刘氏石龙子(Pleistiodon liui),是河南省爬行动物分布新记录种,也是该物种在长江以北地区首次被发现。通过形态学分析,发现刘氏石龙子可能存在雌雄性二态。基于COI基因658 bp序列的系统发育分析显示,大渡石龙子(P. capito)和黄纹石龙子(P. tunganus)聚在一起,然后再与刘氏石龙子聚成一支系,支持先前基于形态数据的黄纹石龙子种组的单系性。During the survey on the amphibian and reptile diversity in Henan Province in late August 2018, eleven individuals of skinks (Scincidae) were captured at the suburb of Tongbai Mountains, Nanyang City. Through morphological analyzing, all of them were identified as Liu’s skink, Plestiodon liui, which is the first record in Henan Province, and the first record in the north region of Yangtze River. Moreover, the characteristics of sexual dimorphisms of the Liu’s skink were clarified. The DNA barcoding COI gene sequences (658 bp) were used to evaluate the phylogenetic placement of P. liui. Examination of phylogenetic analyses recovers the monophyly of the P. capito group, and suggests that P. liui is the sister taxon to P. capito plus P. tunganus.
