Gonadryinus bicarinatus Olmi, Marletta, Guglielmino & Speranza, sp. nov., from Ranomafana National Park (Fianarantsoa Province, Madagascar) is described and illustrated. This represents the first record of Gonadryinus from the Afrotropical region. The genus was previously known only from the Neotropical region, where only one species, G. hansoni Olmi, 1991, is recorded. The new taxon is different from G. hansoni because of the palpal formula 5/3 (4/2 in G. hansoni), the occipital carina complete (incomplete in G. hansoni) and two longitudinal keels present on the dorsal surface of the metapectal-propodeal complex (no longitudinal keels in G. hansoni).
描述并图示了来自马达加斯加菲亚纳兰楚阿省拉努马法纳国家公园的双嵴性腺小蜂Gonadryinus bicarinatus Olmi、Marletta、Guglielmino和Speranza，新种。这是性腺小蜂属在 Afrotropical 地区的首次记录。该属此前仅在新热带地区被发现，在那里仅记录有一个物种，即1991年的汉氏性腺小蜂G. hansoni。新分类单元与汉氏性腺小蜂不同，因为其触须公式为5/3（汉氏性腺小蜂为4/2），后头脊完整（汉氏性腺小蜂不完整），并且在中胸后侧片 - 并胸腹节复合体的背面有两条纵向龙骨（汉氏性腺小蜂没有纵向龙骨）。
