Albunea danai. — Boyko, 2002: 276 –282, figs. 90, 91 (full synonymy).– Eldredge & Evenhuis, 2003: 16. — McLaughlin et al., 2005: 240 (list). Material examined. None. Distribution. U.S.A., Hawaii in 4.8–40.2 m depth (Boyko 2002). Remarks. The records of Albunea thurstoni reported by Titgen (1987) were overlooked previously. These actually represent records of Albunea danai and most of these specimens were designated as paratypes of A. danai (Boyko 1999).Published as part of Boyko, Christopher B., 2010, New records and taxonomic data for 14 species of sand crabs (Crustacea: Anomura: Albuneidae) from localities worldwide, pp. 49-61 in Zootaxa 2555 on pages 54-55, DOI: 10.5281/zenodo.19690

No full textAlbunea holthuisi Boyko & Harvey, 1999 Albunea symnista [sic]. — Ward, 1942: 52 (list), 63 (not Albunea symmysta Linnaeus, 1758). Albunea holthuisi. — Davie, 2002: 27. — Boyko, 2002: 290 –296, figs. 94, 95 (full synonymy). Material examined. Mascarene Islands, Réunion Island: Baie de Saint-Paul, seaward of Cap la Houssaye, soft bottom, 80–120 m, 21 °00’ 94 ’’S, 55 ° 23 ’ 82 ”E, coll. G. Hoarau, 2008: 1 male, 5.8 mm cl (FLMNH UF 18587). Distribution. Zanzibar, Madagascar, Mascarene Islands (Réunion), Seychelles, Indonesia, Malaysia, Australia (Queensland) in 9.1–120 m depth (Boyko 2002, herein). Remarks. This is not the first record of Albunea holthuisi from Réunion. Boyko (2002) suspected that the specimens of Albunea “ symnista ” [sic] reported from Réunion by Ward (1942) were A. holthuisi. The specimen listed above further strengthens that supposition and Ward’s (1942) record is included in the above synonymy list without the “?” that preceded it in Boyko (2002: 290). The collection depth of the present specimen greatly exceeds previously reported depths for this species of up to 34 m (Boyko 2002).Published as part of Boyko, Christopher B., 2010, New records and taxonomic data for 14 species of sand crabs (Crustacea: Anomura: Albuneidae) from localities worldwide, pp. 49-61 in Zootaxa 2555 on page 56, DOI: 10.5281/zenodo.19690

Material examined. Panama (Atlantic): Shimmey Beach, Ft. Sherman, 23 Jan 1971, coll. L. G. Abele: 2 males, 12.0– 13.5 mm cl (USNM 1011075); Isla Grande, 0.5 m (yabby pump), coll. A, Anker and T. Lang, 11 Jun 2006: 1 female, 12.1 mm cl (USNM 1138908); Isla Grande, south side, 0.5 m (suction pump), fine sand, coll. A, Anker, 6–7 Oct 2005: 1 male, 9.1 mm cl, 1 female, 8.8 mm cl (USNM 1138909); Bocas del Toro, Carenero, sea grass, 0.5–1 m, coll. A. Anker, 2 May 2007: 1 female, 6.1 mm cl (USNM 1138910). Distribution. From Virginia to Palm Beach Co., Florida, then from Collier Co., Florida, through the Gulf of Mexico to southern Texas; Panama (Atlantic), in up to 64 m depth (Boyko 2002, herein). Colouration. Carapace, eyes, antennae, and abdomen all generally uniform light tan with strong iridescence and lighter areas along carapace grooves and where setae inserted; antennae with alternating light and dark thin bands on flagellae; pereopods with iridescent sheen on light tan ground colour; setae dark orange in colour (Fig. 1 F, G). Remarks. Identification of the first two Panamanian specimens examined (USNM 1011075) was quite perplexing, as they appeared to be A. catherinae Boyko, 2002, despite that species’ apparent absence from outside the continental southeast United States. The carapace grooves and ocular peduncle/carapace length ratios identify these specimens as A. catherinae. Additionally, the shapes of the indents on the dactyli of pereopods II and III are also as seen in A. catherinae. The acute heel of the dactylus of pereopod IV, while not like that of typical A. paretii (smoothly curved), is not quite like the bluntly projecting dactylus of A. catherinae (Figs. 2 H-J). No other specimens examined in large series of both A. paretii and A. catherinae (see Boyko 2002: 327–330, 343 – 346 for other material examined) showed this acute shape of the heel on pereopod IV. Both of these specimens are mature males and are virtually identical to each other in all aspects. Two additional males collected in the same location on the same date were identical with typical A. paretii (see Boyko, 2002: 329), while another Panamanian ovigerous female collected nearby was likewise clearly A. paretii. Four subsequent specimens provided by Arthur Anker also key out to A. catherinae, with the same acute heel on pereopod IV dactylus, while another specimen collected nearby (see above) is clearly A. paretii. The evidence supports recognition of a highly disjunct population of A. catherinae in Atlantic Panama. The single character difference (acute heel of dactylus of pereopod IV) is not enough to consider these specimens as belonging to a new species. Genetic analysis may give further insight into the relationships between the A. catherinae of Atlantic Panama and those from the main part of the species’ range. It is possible that this disjunct population is the result of transport of larvae via ships’ ballast water from North American ports that was then discharged in the vicinity of the Canal Zone. The Panama Canal Zone Authority prohibits discharge of ballast in the canal since 1999 (Lloyd’s Register 2007), but discharge of such ballast outside the Canal Zone is apparently not restricted. Transport of non-native species from North America to Central America is not impossible, and would be less obvious when the species in question were relatively small, cryptic in habitat, and closely related to native species.Published as part of Boyko, Christopher B., 2010, New records and taxonomic data for 14 species of sand crabs (Crustacea: Anomura: Albuneidae) from localities worldwide, pp. 49-61 in Zootaxa 2555 on pages 57-58, DOI: 10.5281/zenodo.19690
Eremitione lata Boyko & Williams 2023, n. comb.
No full textEremitione lata (Shiino, 1958) n. comb. = Parapseudione lata Shiino, 1958 Distribution: Japanese and Russian sides of the Sea of Japan (Shiino 1958; Kornienko et al. 2018). Hosts: Pagurus brachiomastus (Thallwitz, 1891), P. middendorfii Brandt, 1851, P. minutus Hess, 1865, P. ochotensis Brandt, 1851 (Shiino 1958; Kornienko et al. 2018) Remarks: Parapseudione lata cannot remain in Parapseudione as that genus is synonymized with Pleurocrypta in the present work (see below). Aside from the female having four pairs of biramous pleopods and one pair of uniramous pleopods, all the characters of the females and males indicate that this species belongs to Eremitione, and we transfer it to that genus herein. Markham (1986) and Boyko & Williams (2004) suggested that P. lata might be a synonym of Pseudione hyndmanni (Spence Bate & Westwood, 1867). However, given the geographic distance between Japan and Europe, as well as several morphological differences (e.g., smooth oostegite 1 internal ridge in E. lata vs. digitate in P. hyndmanni; male without pleopods in E. lata vs. with pleopods in P. hydmanni; see Bourdon 1968), we retain E. lata as a distinct species.Published as part of Boyko, Christopher B. & Williams, Jason D., 2023, Nomenclatural and taxonomic changes in parasitic isopods (Isopoda: Epicaridea) including two new families and note on the questionable association between monogeneans and bopyrids, pp. 251-269 in Zootaxa 5258 (3) on page 259, DOI: 10.11646/zootaxa.5258.3.1, http://zenodo.org/record/778021

Septembopyrina An & Boyko & Li 2015, n. gen.
No full textSeptembopyrina, n. gen. DIAGNOSIS: Female: Body slightly distorted, pleomeres distinct. Head fused with first pereomere medially and with well-developed frontal lamina, boundary with head obscure. Maxilliped without palp, barbula with pair of projections. Dorsolateral bosses only on first pereomere. Seven pairs of oostegites, brood pouch widely open. Oostegite 1 of left side and right side slightly different in shape, internal ridges smooth. Seventh oostegite smallest. Pleon of five pleomeres, final one very broad. Five pairs of uniramous flaplike pleopods, uropods lacking. Male: Body width about 1/3 length. Head fused with first pereomere, lateral indentations present. No midventral tubercles. Pereopods smaller posteriorly. Pleon segments distinct ventrally but fused dorsally. ETYMOLOGY: The prefix “septem” (for the seven oostegites of the female) plus the genric name Bopyrina are selected to emphasize the close relationship to Bopyrina; gender feminine. TYPE SPECIES: Septembopyrina tozeumaophila, n. sp., by original designation. OTHER SPECIES: None. REMARKS: The new genus is related to Schizobopyrina Markham, 1985, and Bopyrina in that all have unequal formation of oostegite 1, head somewhat fused with the first pereomere, uniramous pleopods and lack uropods. Markham (1985a) separated Schizobopyrina from Bopyrina and transferred 10 species from Bopyrina to Schizobopyrina. He showed that Schizobopyrina females have a maxilliped palp, elongate oostegites 2–5, and at least lateral separation of the pleomeres, but Bopy ‐ rina females lack a maxilliped palp, have tiny oostegites 2–5, and pleomere fusion on the shorter side. This new genus is most closely related to Bopyrina, but Septembopyrina, n. gen., has the female pleomeres distinct on both sides and seven pairs of oostegites. The new genus also can be distinguished from Schizobopyrina by the weakly asymmetrical body (strongly asymmetrical in Schizobopy ‐ rina), five pairs of uniramous pleopods (four pairs in Schizobopyrina), and maxilliped without palp (with palp in Schizobopyrina). The presence of seven pairs of oostegites is very uncommon and considered a primitive character state in bopyrids (Boyko and Williams, 2010); the only prior records from any bopyrines are from Bopyrinella albida and Capitetragonia elliptica, but the type species of Septembopyrina, n. gen., does not otherwise resemble these two species except in this one character.Published as part of An, Jianmei, Boyko, Christopher B. & Li, Xinzheng, 2015, A Review Of Bopyrids (Crustacea: Isopoda: Bopyridae) Parasitic On Caridean Shrimps (Crustacea: Decapoda: Caridea) From China, pp. 1-85 in Bulletin of the American Museum of Natural History 2015 (399) on page 62, DOI: 10.1206/amnb-921-00-01.1, http://zenodo.org/record/461250
