description: Key to laophontid genera with reduced P2 endopod There are no published descriptions of male <i>Coullia</i> [<i>sensu</i> Hamond (1973)], but referring to personal observations of several undescribed species of <i>Coullia</i>, Fiers (1992a) confirmed that the sexual dimorphism in the P3 endopod and the armature pattern in the male P5 are exactly the same as in <i>Hemilaophonte</i> and <i>Phycolaophonte</i>. Fiers (1992a–b), Lee and Huys (1999) and, more recently, Gómez and Boyko (2006), recognized a close relationship between <i>Coullia</i>, <i>Phycolaophonte</i>, <i>Hemilaophonte</i>, <i>Robustunguis</i> Fiers, 1992 and <i>Psammoplatypus</i> Lee &amp; Huys, 1999, based on the reduced P2 endopod (smaller than P3 endopod), the swimming leg sexual dimorphism (P3 endopod ♁) and the ovate shape of the female P5 exopod. McCormack (2006) added a new genus <i>Carraroenia</i> McCormack, 2006 which appears to be most basal in this lineage. The five genera currently recognized in this lineage can be differentiated as follows: 1 P1 excessively enlarged with arched claw; reaching to posterior end of caudal rami; equivalent to about two-thirds of body length............... <i>Robustunguis</i> – P1 not excessively enlarged......................................................................... 2 2 P4 exp-2 with inner seta in both sexes; ♁ P3 endopod 3-segmented........... 3 P4 exp-2 without inner seta in both sexes; ♁ P3 endopod 2-segmented......4 3 P2 exp-2 with inner seta; P3 exp-3 with 6 setae/spines; P5 exopod &amp;female; with 6 elements.................................................................................... <i>Carraroenia</i> – P2 exp-2 without inner seta; P3 exp-3 with 5 setae/spines; P5 exopod &amp;female; with 4 elements.......................................................................... <i>Psammoplatypus</i> 4 P4 exopod 2-segmented....................................................... <i>Hemilaophonte</i> – P4 exopod 3-segmented.................................................................... <i>Coullia</i>
