A new species of skink, Trachylepis gonwouoi sp. nov. is described from Cameroon and the Republic of the Congo. It differs from all other species of Trachylepis in Central-West Africa by a combination of number of keels on dorsal scales (3-5); moderate SVL (maximum size of 80 mm); number of scale rows at midbody (28-34); number of supracilliaries (6-10); a well defined lateral white stripe, bordered by black, extending from under the eye to the insertion of the hind limb; and a ventral color in life of bright blue-green. Trachylepis gonwouoi sp. nov. was found in association with disturbed forest at elevations from 50 to 1050m. This species is syntopic with T. affinis and T. maculilabris. In order to aid in the identification of Trachylepis in West and Central Africa with the addition of T. gonwouoi sp. nov., we provide an updated key to the Trachylepis found from Mauritania through the Democratic Republic of the Congo. This key combines previous literature that treated Western and Central African taxa separately and represents the most comprehensive key for Trachylepis in West-Central Africa to date.
一种新的石龙子物种，即贡武奥氏糙鳞石龙子（Trachylepis gonwouoi sp. nov.）在喀麦隆和刚果共和国被发现并得以描述。它与中西非的所有其他糙鳞石龙子物种不同，其特征组合包括：背鳞的棱数（3 - 5）；中等的体长（最大80毫米）；身体中部的鳞片行数（28 - 34）；眉上鳞片数（6 - 10）；一条清晰的白色侧条纹，边缘为黑色，从眼睛下方延伸至后肢插入处；以及活体时腹部为亮蓝绿色。贡武奥氏糙鳞石龙子（Trachylepis gonwouoi sp. nov.）发现于海拔50至1050米的受干扰森林中。该物种与亲缘糙鳞石龙子（T. affinis）和斑唇糙鳞石龙子（T. maculilabris）同域分布。为了在新增贡武奥氏糙鳞石龙子（T. gonwouoi sp. nov.）的情况下，帮助鉴定西非和中非的糙鳞石龙子，我们提供了一份从毛里塔尼亚到刚果民主共和国发现的糙鳞石龙子的更新检索表。这份检索表整合了之前分别处理西非和中非分类群的文献，是迄今为止中西非糙鳞石龙子最全面的检索表。
