| Studies on the reproductive biology of Dorstenia species are scarce. We analyzed the sexuality, floral biology, and diaspore dispersal of Dorstenia arifolia and D. bonijesu, including their breeding systems and pollinators, in natural populations from Minas Gerais state, southeastern Brazil. We report here, for the first time, the occurrence of both unisexual (male) and bisexual coenanthia on the same individuals of Dorstenia arifolia, while only bisexual coenanthia were observed in D. bonijesu. In both species all coenanthia were long-lived and bisexual coenanthia were protogynous. We observed the occurrence of self-compatibility and myophily in Dorstenia arifolia, a species which was pollinated by small Lauxaniidae flies. Those insects not only used... |

| The genus Physoclypeus Hendel, 1907 has its distribution restricted to the Neotropical region. In this study, its species have been redescribed, three new combinations have been proposed, three lectotypes have been designated, seven new species have been described, and an identification key to the species is presented. An updated list of species of Physoclypeus is presented as: P. annulatus Hendel, 1925; P. coquilletti (Hendel, 1908); P. farinosus (Hendel, 1925); P. flavus (Wiedemann, 1830); P. hendeli sp. nov. (Type locality, Jamaica, N. Irish Town); P. lineatus (Williston, 1896) new comb.; P. montanus (Becker, 1919) new comb.; P. plaumanni sp. nov. (Type locality, Brazil, Santa Catarina); P. risaraldensis sp. nov. (Type locality, Colombia, Risaralda); P.... |
