Philippiphonte Huys & J. Lee 2018

The genus is placed in the subfamily Laophontinae based on the following synapomorphies: (a) male antennule with up to three segments distal to geniculation, (b) mandible without discrete exopod, (c) maxilliped with maximum two setae on syncoxa, (d) P1 enp-1 without inner seta, (e) P2 enp-2 without outer spine, (f ) proximal outer setae of female P5 exopod with distinctly separated insertion sites, and (g) absence of cup-shaped transformed pores on legs, somites or caudal rami. Unique autapomorphies that define the genus Philippiphonte include (a) the extremely dorsoventrally flattened, porcellidiid-like body shape in both sexes, (b) the inverted trapezoid shape of the rostrum, (c) the flattened caudal rami with elaborate spinular ornamentation along inner and outer margins, (d) the remarkably slender antennules in the ?, characterised by a very elongate third segment, (e) basal seta of mandibular palp originating from small articulating socle, (f ) P1 exp-1 with long outer spine, extending beyond distal margin of exp-3 and bearing stiff spinules, (g) legs 2–4 with widely separated members connected by narrow intercoxal sclerites and with transversally elongate bases, becoming progressively longer from P2 to P4, and (h) P5 baseoendopod subcylindrical, elongate, backwardly recurved and fused at base to pleural wall of supporting somite in both sexes.
