West African mangroves host seven species of sesarmid crabs; three of which belong to the recently established genus Guinearma Shahdadi & Schubart, 2017, i.e., G. alberti (Rathbun, 1921), G. huzardi (Desmarest, 1825), and G. kamermani (De Man, 1883). The last species was originally described based on a single male specimen, and no further record has been published so far. Moreover, the three species of Guinearma were previously only briefly and superficially described. Along with some new records for G. kamermani, here we newly describe and illustrate the three species of Guinearma in detail, and discuss their diagnostic key features (mostly chelar characters). To facilitate their identification in the field, the other four species of West African Sesarmidae (i.e., Armases elegans (Herklots, 1851), Chiromantes angolense (De Brito Capello, 1864), C. buettikoferi (De Man, 1883), and Metagrapsus curvatus (H. Milne Edwards, 1837)) are also illustrated and an identification key is provided.
