An adult male of Alloscorpiops wongpromi Kovařík et al., 2013 was raised from birth, and its five exuviae (instars 2 through 6) were compared to the resulting adult. This adult was contrasted with the original holotype male specimen, which was determined to be only a subadult after the fifth ecdysis. The hemispermatophore of A. wongpromi is illustrated and described here for the first time. In addition to morphological analysis we also describe the karyotype of Alloscorpiops wongpromi (2n=95). Based on comparative analysis of pectinal tooth counts, it is determined that the holotype of A. troglodytes Lourenço & Pham (2015) represents a juvenile.
