Laniporchestia Lowry & Myers, 2019 Platorchestia Bousfield, 1982: 26 (in part.) Platorchestia group 3 of Miyamoto & Morino, 2004: 69. Laniporchestia Lowry & Myers, 2019: 53, fig. 23. Type species. Platorchestia lanipo Richardson, 1991, monotypy. Included species. Laniporchestia contains 1 species: L. lanipo (Richardson, 1991). Ecological type. Tree/moss-hopper. Diagnostic description ( male ). Based on Richardson (1991). Head. Antenna 2 peduncular articles slender or slightly incrassate (?). Mandible left lacinia mobilis 5-cuspidate. Labium without inner lobes. Maxilliped palp slender; article 2 with distomedial lobe; article 4 reduced, button-shaped. Pereon. Gnathopod 1 sexually dimorphic; subchelate; coxa much smaller that coxa 2; posterior margin of carpus and propodus each with lobe covered in palmate setae; propodus anterior margin with 2 groups of robust setae, ���subtriangular��� with well-developed posterodistal lobe, palm transverse; dactylus dactylation unknown. Gnathopod 2 subchelate; propodus palm acute, without palmar sinuses; without proximal spine or thumb defining palm; without large projection near dactylar hinge; dactylus slightly curved, longer than palm, attenuated distally. Pereopods 3���7 dactyli bicuspidactylate. Pereopod 4 subequal or slightly shorter than pereopod 3; carpus similar in length to that of pereopod 3; dactylus homobasidactylate, similar to pereopod 3 dactylus, not thickened proximally or notched. Pereopod 6 subequal in length to pereopod 7, not incrassate; basis moderately expanded; male merus expanded, carpus slightly or not expanded. Pereopod 7 not incrassate ; basis broadly expanded, posterior margin with distinct minute serrations, each with a small seta, posterodistal lobe present, shallow, broadly rounded; merus and carpus unexpanded, subrectangular; carpus shorter than propodus; propodus slender, length 8 �� width; propodus without large distal tuft of setae. Oostegites (female) setae with simple smooth tips. Pleon. Pleopods all slightly reduced, rami not articulated, shorter than peduncles. Uropod 1 peduncle distolateral robust seta absent; exopod without marginal robust setae; endopod with marginal robust setae in 1 row. Uropod 2 exopod with marginal robust setae in 1 row; endopod with marginal robust setae in 1 row. Uropod 3 ramus shorter than peduncle. Telson apically incised, with 4 robust setae per lobe. Remarks. Laniporchestia is similar to the Japanese genus Morinoia. It differs from Morinoia Lowry & Myers, 2019 as follows: maxillipedal palp slender (broad in Morinoia); telson rounded distally (tapering distally in Morinoia). Distribution. Hawaii. Oahu (Richardson 1991).
