260087F9FFBE3245FF6DF8B3FE5FF807.taxon	discussion	Remarks. In Koekotroides gen. nov., gnathopod 1 lacks the lobes covered in palmate setae that are present on gnathopod 1 of males and females of most other Arcitalitridae. They are, however, also absent in the type genus Arcitalitrus Hurley, 1975, in Insulariator Lowry & Myers 2019, in Solitroides Suzuki, Nakano, Nguyen, Nguyen, Morino & Tomikawa 2017 and in Myanmarorchestia Hou & Zhao, 2017. The single known species of Insulariator from Tasmania differs from Koekotroides gen. nov. in lacking spear-like robust setae on the propodus of gnathopod 1 and in the form of the pleopods that in Insulariator have broad peduncles and have rami with partial articulations. It also has a large eye, epimeron 3 without a concavity on the distal margin and an extraordinary elongate gnathopod 2 in both sexes. Koekotroides gen. nov. shares many character states with Arcitalitrus, but differs markedly in the form of the pleopods. In Arcitalitrus, the pleopod peduncles are broad and setose, the rami are articulated and heavily setose and pleopod 3 is very reduced, sometimes vestigial. Koekotroides gen. nov. is quite similar to the Vietnamese genus Solitroides. It shares with that genus the arcuate maxilliped exopodite, the spear-like robust setae on the gnathopod 1 propodus, the pleopods without setae on the peduncles and with rudimentary indication of articles on the rami and in the small, terminally setiferous oostegites. It differs from it in the broad, round termination of the exopodite of the maxilliped, the evenly convex ventral margin of epimeron 3 and the lack of long marginal robust setae on the telson. Myanmarorchestia is very different from Koekotroides gen. nov. in the form of the maxilliped which does not have an arcuate exopodite, its peculiar gills with their numerous filamentous projections, the nonbulbous uropod 3 peduncle and the telson lacking long marginal robust setae. Because of the unique gills, this genus could be placed in a new monophyletic family within the Protorchestoidae. For the moment, we retain it in the Arcitalitridae, which currently incorporates all the known world simplidactylate forest hoppers. Koekotroides gen. nov. has three autapomorphies that differentiate it from all other Arcitalitridae, the bulbous peduncle of uropod 3, the concave distal margin of epimeron 3 and the smooth margins of the pleopod rami with no indication of even rudimentary articulations. Koekotroides gen. nov. consists of two species groups. Group 1 (K. moowhitihauuru sp. nov., K. taapinea sp. nov., K. tewhaarua sp. nov. and K. maene sp. nov.) occurs on the Three Kings Islands, North Cape, Poor Knights Islands and in Auckland and Whanganui, while Group 2 (K. pekehau sp. nov. and K. ngaokiroa sp. nov.) is limited to Te Paki, Ahipara and Maungataniwha Ecological Districts (Fig. 1). Group 1 retains the more ancestral character state, having a distinct article 4 on the maxilliped palp. This character state is shared by all other world Arcitalitridae and Protorchestiidae except for the species in Group 2 of Koekotroides gen. nov. in which article 4 is lost. The loss of the maxilliped article 4 in Koekotroides gen. nov. is a homoplasy. It is not a synapomorphy with this character state in the Talitroidae.	en	J. - P, Olivier, Myers, Alan A., Shepherd, Lara D.

260087F9FFB9324FFF6DFF0FFAABFD3B.taxon	discussion	Remarks. Koekotroides moowhitihauuru sp. nov. is most closely related to K. taapinea sp. nov. It differs from that species in the structure of epimera 2 and 3. In K. moowhitihauuru sp. nov., the posterior margin of epimeron 2 is nearly straight along the distal half, with or without a small process at the posterodistal corner. In K. taapinea sp. nov., the posterior margin is evenly concave, and the posterodistal margin is drawn out into a long subacute process. The concavity along the ventral margin of epimeron 3 is also more strongly defined in K. moowhitihauuru sp. nov. than in K. taapinea sp. nov. Koekotroides moowhitihauuru sp. nov. is also similar to K. tewhaarua sp. nov., but that species has epimeron 3 with a distinctly crenulate posterior margin, and a much longer distolateral robust seta.	en	J. - P, Olivier, Myers, Alan A., Shepherd, Lara D.

260087F9FFB13249FF6DFE1FFBB8F8FB.taxon	etymology	Etymology. Te whārua is a valley hollow or depression, referring to the concavities and depressions of epimeron 3. As well as representing concavities, depressions, valleys and hollows, Whāwhārua also represents descent from a female ancestor in the whakapapa (genealogy). Te whārua, a mokopuna (grandchild) of Papatūānuku (our Earthmother) creates everlasting symbiotic relationships within our ecosystem that lead to maintaining a healthy and thriving environment. Te whaarua, the valleys of life, where natural features are created by the embracing energies of Papatūānuku (Earth mother) and Ranginui (Sky father) to bring forth a complementary state of balance in our environment and in humanity. From the mountains to the valleys to the rivers to the oceans, te waiora (waters of life), flow unceasingly through the channels of te whaarua.	en	J. - P, Olivier, Myers, Alan A., Shepherd, Lara D.

260087F9FFAF3251FF6DFA8EFB54FA0F.taxon	etymology	Etymology. Pekehau refers to jumping or leaping in the wind. Pekehau expresses the strength and vitality of the species to survive in the taiao (natural environment) while being critical contributors to the ongoing health and wellbeing of our ecosystems. Pekehau utilises the natural forces of the hau (winds) to carve pathways of life through the habitats of this species, which include Unuwhao (whao — carve), the misty environs of Kohuroa (kohu — mist, roa — long) and beyond to Haupātōtō (the beating wind).

260087F9FFAB325DFF6DFA76FB35FBEF.taxon	description	Description. Adult female 6.0 – 8.0 mm. Head. Antenna 1 extending to at least half of the way along peduncle article 5 of antenna 2; article 3 of peduncle subequal in length with article 2; flagellum consisting of 4 – 5 articles. Antenna 2 as long as head and first 2.5 – 3.5 pereonites combined, article 4 length 2.5 times breadth; article 5, 1.7 times length of article 4; flagellum subequal to or a little longer than peduncle, consisting of about 12 – 15 articles. Maxilliped strongly splayed; endopodite apex subacute, inner margin weakly arcuate; exopodite distally arcuate with subacute apex; palp article 2 without distomedial lobe; article 4 absent. Pereon. Gnathopod 1 coxa sub-trapezoidal, anterior margin nearly straight; basis slightly broadening distally; merus posterior margin without lobe covered in palmate setae; carpus elongate, posterior margin evenly convex, without lobe covered in palmate setae; propodus, about 0.6 – 0.7 times length of carpus, anterior margin nearly straight, posterior margin convex, posterior margin with 3 long, straight or weakly curved, spear-like robust setae, palm simple. Gnathopod 2 basis slender, 3.5 times as long as broad; merus produced posterodistally into a lobe covered in palmate setae; carpus stout, posterior margin lobed, covered in palmate setae; propodus moderately slender and mitten-shaped in both sexes (femipod), slightly longer than carpus, distal lobe apically rounded, covered in palmate setae; dactylus very short. Pereopod 3 – 4 parallel-sided in lateral view, anterior margin concave distally in frontal view. Pereopod 5 basis broad medioproximally, narrower distally; carpus and merus subequal in length; propodus approximately 1.4 times longer than carpus. Pereopod 6 basis subelliptical to subrectangular, anterior margin convex, posterior margin weakly convex to nearly straight; propodus approximately 1.3 times length of carpus. Pereopod 7 basis orbicular to weakly elliptical, almost, as broad as long, posterior margin with small serrations each with a small seta; merus, carpus and propodus each progressively a little longer than the preceding article. Pleon. Epimeron 1 shortest, posterior margin nearly straight; posteroventral corner nearly a right angle. Epimeron 2 ventral margin nearly straight to weakly convex, deepest posteriorly; posteroventral corner with or without small subacute process; posterior margin nearly straight along distal half, widest medially. Epimeron 3 as deep as epimeron 2 at anteroventral corner; ventral margin convex anteriorly, concave posteriorly; posteroventral corner with or without small, rounded or subacute process; posterior margin weakly notched, sinuate. Pleopods 1 – 3 biramous; exopodites usually slightly shorter than endopodites. Pleopod 1 endopodite 0.4 times length of peduncle. Pleopod 2 approximately 0.8 times length of pleopod 1, endopodite 0.4 times length of peduncle. Pleopod 3 shortest and narrowest, endopodite 0.4 times length of peduncle. Uropod 1 peduncle longer than subequal rami, outer margin with 2 dorsal robust setae distally; distolateral robust seta approximately 0.5 times length of exopodite; exopodite without dorsal robust setae; endopodite with 2 – 3 dorsal robust setae. Uropod 2 peduncle subequal in length with endopodite; endopodite a little longer and stouter than exopodite, with 2 – 3 marginal robust setae; exopodite without marginal robust setae. Uropod 3 peduncle bulbous, with 1 very long lateral robust seta; ramus approximately 0.3 times length of peduncle, with 1 long apical seta, sometimes with an additional short seta. Telson as broad as long, undulate, not incised apically, deep longitudinal furrow present ventrally, 1 large apical robust seta and 3 large dorsal robust setae on each side.	en	J. - P, Olivier, Myers, Alan A., Shepherd, Lara D.

260087F9FFAB325DFF6DFA76FB35FBEF.taxon	discussion	Remarks. Koekotroides ngaokiroa sp. nov. shares with K. pekehau sp. nov. the complete loss of article 4 on the maxilliped palp and the presence of 3 dorsal setae on the telson. It can be distinguished from K. pekehau sp. nov. by the simple palm on the propodus of gnathopod 1 in both sexes (parachelate in K. pekehau sp. nov.).	en	J. - P, Olivier, Myers, Alan A., Shepherd, Lara D.
