Australorchestia Serejo & Lowry 2008
No full textAustralorchestia Serejo & Lowry, 2008 Australorchestia Serejo & Lowry, 2008: 163. Type species. Australorchestia occidentalis Serejo & Lowry, 2008, original designation. Included species. Australorchestia includes 2 species: A. occidentalis Serejo & Lowry, 2008; A. tantabiddyensis sp. nov. Diagnostic description (based on male). Head Eyes medium (greater than 1 / 5 to 1 / 3 head length). Antenna 1 short, not longer than article 4 of antenna 2 peduncle. Antenna 2 peduncular articles slender to slightly incrassate ; peduncular article 3 without ventral process; final flagellar article large, cone-shaped, forming virgula divina. Mandible left lacinia mobilis 4- 5 -dentate . Maxilliped palp article 2 distomedial lobe well developed; article 4 reduced, button-shaped. Gnathopod 1 chelate; posterior margin of carpus and propodus each with lobe covered in palmate setae . Gnathopod 2 subchelate; merus and carpus free; dactylus attenuated distally. Pereopods 3–7 cuspidactylate. Pereopods 5–7 without setae along posterior margin of dactylus. Pereopods 6–7 not sexually dimorphic; without row of short setae along posterior margin of dactyli. Pleonites 1–3 without dorsal spines. Pleopods all well developed, biramous . Epimera 1–3 without vertical slits. Uropod 1 rami without apical pear-shaped setae; outer ramus slender, with marginal robust setae. Uropod 3 well developed; ramus subequal in length to peduncle. Telson apically incised, as broad as long or longer than broad with 5–6 robust setae per lobe. Remarks. In the original description of Australorchestia occidentalis the male antenna 2 is considered to be slightly incrassate, the left lacinia mobilis has 4 cusps, the male gnathopod 1 is considered as subchelate and the male pereopod 7 is considered to be slightly expanded. In the new species, A. tantabiddyensis, male antenna 2 is slender to slightly incrassate, the left lacinia mobilis has 5 cusps, in the male gnathopod 1 the palm of the propodus is acute but then forms a sharp angle to become obtuse so that the gnathopod is considered as chelate, and the pereopod 7 has the merus and propodus slightly expanded as in A. occidentalis. The generic diagnosis has been amended to document these changes. The relationship of Australorchestia to other talitrid genera is unclear. The obtuse palm on gnathopod 1 is unusual among talitrids. Australorchestia is most similar to Africorchestia Lowry & Coleman, 2011. Both genera have a reduced, button-shaped maxillipedal palp article 4, palmate lobes on the carpus and propodus of male gnathopod 2, well developed pleopods, robust setae on the outer ramus of uropod 1 and 5–10 robust setae per lobe on the telson. They differ in the chelation of gnathopod 1, the distal shape of the dactylus of male gnathopod 2, the sexual dimorphism of pereopods 6 and 7 and the condition of the dorsum of pleonites 1–3. Both genera are considered to be post-Gondwanan.Published as part of Lowry, J. K. & Springthorpe, R.

No full textTropicorchestia gen. nov. Type species. Tropicorchestia derbyensis gen. nov., sp. nov. Included species. Marsh-hopper. Tropicorchestia includes two species: T. derbyensis sp. nov.; T. glasbyi sp. nov. Etymology. The name refers to its geographic location in tropical Australia. Diagnostic description (based on male). Eyes medium (greater than 1 / 5 to 1 / 3 head length). Antenna 1 short, slightly longer than article 4 of antenna 2 peduncle. Antenna 2 peduncular articles slender; peduncular article 3 without ventral process; final flagellar article large, cone-shaped, forming virgula divina. Mandible left lacinia mobilis 4 -dentate. Maxilliped palp article 2 distomedial lobe well developed; article 4 reduced, button-shaped. Gnathopod 1 subchelate ; posterior margin of merus, carpus and propodus each with lobe covered in palmate setae. Gnathopod 2 subchelate ; merus and carpus free; dactylus attenuated distally. Pereopods 3–7 cuspidactylate. Pereopods 5–7 without setae along posterior margin of the dactylus. Pereopods 6–7 not sexually dimorphic, without row of short setae along posterior margin of dactyli. Pleonites 1–3 without dorsal spines. Pleopods all well developed . Epimera without slits just above ventral margins. Uropod 1 rami without apical spear-shaped setae; outer ramus slender; without marginal robust setae. Uropod 3 well developed; ramus shorter than peduncle. Telson entire, with 3–6 robust setae per lobe. Remarks. The Indo West Pacific genera Tropicorchestia gen. nov., Floresorchestia Bousfield, 1984 and Lanorchestia Miyamoto & Morino, 2010 appear to be very similar. They share nearly all generic-level characters (Lowry & Bopiah 2012). Floresorchestia differs from Tropicorchestia and Lanorchestia in having epimeral slits. Lanorchestia differs from Floresorchestia and Tropicorchestia in having long first antennae and slightly shortened third pleopods.Published as part of Lowry, J. K. & Springthorpe, R.

Antenna 2 peduncular article 2 cone gland reaching at least to end of peduncular article 3; article 4 subequal to article 5. Mandible palp article 1 about as long as broad, inner margin produced distally; article 2 subequal to article 3. Pereon.

Pereopod 7 basis expanded, posterior margin convex and tapering distally. Habitat. Marine epibenthic, living among coral rubble, sponges, sand and low algal turf in 10 to 20 m depth. Remarks. Dulichiella pacifica has four spines on the distolateral crown of male gnathopod 2 and a 7-7-7- 5-4/6-2 pleonite/urosomite formula. Four other species share these characters: D. appendiculata; D. fresnelii; D. lecroyae; and D. cuvettensis. Dulichiella pacifica is most similar to D. cuvettensis and D. fresnelii. It differs from D. cuvettensis in having one accessory spine on the dactyli of pereopods 5 to 7 (two accessory spines in D. cuvettensis) and in having bunches of long, slender setae on the carpus and propodus of male pereopods 6 and 7 which are absent in D. cuvettensis. Dulichiella pacifica differs from D. fresnelii in the posterior margin of the basis of pereopod 6 which is concave in D. pacifica and straight in D. fresnelii and in the posterior margin of the basis of pereopod 7 which is straight in D. pacifica and tapering distally in D. fresnelii. Dulichiella pacifica is a common shallow-water species in Singapore, New Guinea, New Caledonia, the Solomon Islands and north-eastern Australia. Dulichiella has not been reported from Micronesia (J.L. Barnard 1965) or Fiji (Myers 1985).

Type locality. North side of Cape Sorell, about 400 m outside Hannants Bight on a line toward large bluff of Ocean Beach, Tasmania, Australia (42°11.4’S 145°11.08'E), 30 m depth. Etymology. Named for the Macquarie Harbour pilot boat that put out on 23 July 1830 to guide the Government brig Tamar through the difficult harbour entrance known as 'Hells Gates'.
