Squillidae is the largest family in the Stomatopoda, with 47 genera to date. Phylogenetic analyses have shown Squilla Fabricius, 1787 and Oratosquilla Manning, 1968 to be para- or polyphyletic. Two poorly documented species within these genera, Squilla parva Bigelow, 1891 (eastern Pacific) and Oratosquilla kempi (Schmitt, 1931) (western Pacific) are not closely related to the respective type species of the genera in which they are currently placed. We herein redescribe S. parva and O. kempi based on type and other material, and propose two new genera for their reception, increasing the number of squillid genera to 49.
