Ethiopia is known for its highly endemic and rich herpetofaunal diversity shaped by its biogeographical patterns. Here, a new species of skink, Trachylepis boehmei sp. nov., is described from the Ethiopian Highlands. It differs from its congeners in having smooth uncarinated dorsal scales, 26-29 scale rows around midbody, a slender body of small size, a relatively short tail, a low eye-snout distance and a unique colour pattern with 6-8 darkish brown dorsal stripes. Based on morphological characteristics, its biogeographical pattern and comparisons with other similar congeners this new species is closely related to Trachylepis megalura. A published new record of Trachylepis wingati for the Kafa region is re-examined and identified as T. megalura. An updated comprehensive key to the Trachylepis found in Ethiopia is provided. In the context of ongoing phylogenetic and taxonomic revisions of Trachylepis and its species complexes the presence of further cryptic taxa can be expected also for the Ethiopian biodiversity hotspots. Consequently, the need of further herpetological investigations in this region of ecological importance is stressed.
埃塞俄比亚以其高度流行且丰富的爬行动物区系多样性而闻名，这种多样性是由其生物地理模式塑造的。在此，一种新的石龙子物种，即博氏糙鳞蜥（Trachylepis boehmei sp. nov.），是从埃塞俄比亚高地描述的。它与其同属物种的区别在于具有光滑无棱的背鳞、身体中部周围有26 - 29排鳞片、体型小且细长、尾巴相对较短、眼鼻距离短以及具有独特的颜色图案，有6 - 8条深褐色的背纹。基于形态特征、其生物地理模式以及与其他相似同属物种的比较，这个新物种与巨尾糙鳞蜥（Trachylepis megalura）密切相关。对已发表的关于卡法地区温氏糙鳞蜥（Trachylepis wingati）的新记录进行了重新检查，并确定为巨尾糙鳞蜥。提供了一份埃塞俄比亚发现的糙鳞蜥的更新综合检索表。在对糙鳞蜥及其物种复合体正在进行的系统发育和分类学修订的背景下，可以预期埃塞俄比亚生物多样性热点地区也存在更多的隐性分类单元。因此，强调了在这个具有生态重要性的地区进行进一步爬行动物学研究的必要性。
