Recent phylogenetic analyses of Ocyptamus Macquart, 1834 (Diptera, Syrphidae) confirmed the paraphyly of this genus and provided evidence to divide it into several monophyletic subgroups, of which the largest is the clade traditionally treated as the Ocyptamus tristis species group. This group is here redefined, divided into the genera Pelecinobaccha Shannon, 1927 and Relictanum gen. nov., and revised along with the closely related and newly resurrected genus Atylobaccha Hull, 1949. Twenty-four new species (22 in Pelecinobaccha and two in Relictanum) are described and 35 species (27 in Pelecinobaccha, seven in Relictanum and Atylobaccha flukiella Curran, 1941) are redescribed. Pelecinobaccha is divided into four species groups (P. adspersa species group, P. brevipennis species group, P. peruviana species group and P. susio species group). An identification key, illustrations and distribution maps for all species from this study are also presented.
近期对1834年的奥西普塔姆斯属（双翅目，食蚜蝇科）进行的系统发育分析证实了该属的并系性，并提供了将其划分为几个单系亚组的证据，其中最大的一个分支是传统上被视为奥西普塔姆斯三斑种组的进化枝。在此对该组进行重新定义，将其划分为1927年的佩莱西诺巴卡属和新属残遗属，并与密切相关且新复活的1949年的阿蒂洛巴卡属一起进行修订。描述了24个新物种（佩莱西诺巴卡属22个，残遗属2个），重新描述了35个物种（佩莱西诺巴卡属27个，残遗属7个，以及1941年的阿蒂洛巴卡弗卢基埃拉种）。佩莱西诺巴卡属分为四个种组（分散佩莱西诺巴卡种组、短翅佩莱西诺巴卡种组、秘鲁佩莱西诺巴卡种组和苏西奥佩莱西诺巴卡种组）。还给出了本研究中所有物种的鉴定检索表、插图和分布图。
