Key to species of Microthalestris Sars, 1905 As pointed out above, Brady’s (1910) description of M. gracilis is rudimentary, his illustrations are far from precise and the armature formula of P2–P5 is misleading. The species is consequently omitted from the key and the reader is advised to consult the original description. The same applies to M. littoralis which is only known from the female and for which no information on swimming leg armature exists. 1. P3–P4 exp-1 without inner seta, exp-3 with eight and seven spines/setae, respectively; P 5 ♀ exopod with elements; P5 exopod ♂ 1-segmented with seven elements........................................ M. forficuloides (Scott & Scott, 1894). – These characters not combined..........................................................................2. 2. P2–P3 enp-1 without inner seta; P3 endopod ♂ with inner seta on enp-3 [0.1.12 + apo]; caudal ramus seta IV with distinctly bulbous, basal swelling..................................................... M. bulbosa (Gee, 2006) comb. nov. – P2–P3 enp-1 with inner seta; P3 endopod ♂ without inner seta on enp-3 [1.1.02 + apo]; caudal ramus seta IV not modified.3. 3.
