MARESTE GAMMARIDEAN AMPHIPODA

Figure 24. — Lepechinellidae: a, accessory flagellum [see Pleustldae, Ampeliscidae]; b, 



coxae 1-4, left to right, note acumination [see Atylidae, Ampeliscidae]; c, urosomites 1-3, 



left to right, note amalgamation of segments 2-3, presumably occurring in all lepechinel- 



Hds [see Pleustidae, Paramphithoidae]; d, telson. 



Presumably all lepechinellids have coalesced inner lobes on the lower lip and thus differ 



from Paramphithoidae. Kuriidae, Dexaminidae, and Prophliantidae lack mandibular palps,
