Albunea holthuisi Boyko & Harvey 1999
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

Japan (type locality: Honshu Island), Taiwan, Philippines, Singapore, Malaysia, Vietnam, Australia (Queensland, Victoria) and India (present study).</p> <p> <b>Remarks</b>. The key morphological characteristics of the specimens in identifying them as <i>A. groeningi</i> are as follows: CG11 absent, and anterior margin of carapace with 8–11 spines on both sides of ocular sinus; CG1 to CG10 show the same pattern as in the holotype. The rostrum, triangular ocular plate and distal peduncular segment with cornea at tip are present. The pereopod III dactylus has the base to heel deeply concave, heel to tip with a broadly concave indent and slightly concave indent present at the midpoint of the proximal margin, tip acute, and tip to base smoothly convex. The telson of the male specimen is elongated with the length greater than width and the distal tip rounded with a median indentation. Additional measurements of a male 6.30 mm CL and 7.43 mm CW include: right pereopod I length 4.50 mm, width 5.48 mm; pereopod II length 5.46 mm, pereopod III length 6.87 mm, telson length 2.85 mm, abdominal somite I dorsal length 7.74 mm, abdominal somites II–VI dorsal (combined) length 5.71 mm (Figs. 1, 2).</p> <p> <i>Albunea groeningi</i> is very similar to <i>A. symmysta</i> and <i>A. okinawaensis</i> Osawa & Fujita, 2007 but all three species can be distinguished on the basis of their carapace groove pattern, pereopod I–III shape and telson structure (see Osawa & Fujita 2007). The present specimens of <i>A. groeningi</i> are smaller than many previously reported; males are known up to 14.4 mm CL. The species was previously reported from southern Japan southward to Western Australia and Victoria down to 45.7 m depth (Serene & Umali 1965; Boyko 2002) but was unknown west of this range. In general, albuneids are uncommonly collected and poorly known due to their peculiar burrowing habits (Boyko 2002; Osawa & Fujita 2012). Only three species (<i>A. symmysta, A. occulta, A. thurstoni</i>) were previously reported from the Indian coast (Henderson 1893; Serene & Umali 1965; Subramoniam & Panneerselvam 1985; Roy & Mitra 2010; Marimuthu <i>et al.</i> 2015; Reshmi <i>et al.</i> 2017; Kumar <i>et al.</i> 2018) and <i>A. groeningi</i> is newly recorded from India, specifically from West Bengal on the east coast. Additional surveys and taxonomic studies are required to better ascertain the true diversity of sand crabs in India.</p>Published as part of <i>Yogesh Kumar, J.

DISTRIBUTION. — Known only from Sicyonia truncata (Kubo, 1949) and S. curvirostris Balss, 1913, from the vicinity of New Caledonia. Depth: between 260 and 522 m. DESCRIPTION Female (Figs 1; 2) Based on holotype. Body length 4.43 mm, maximal width 3.15 mm, head length 1.05 mm, head width 1.20 mm. Pereon somewhat sinuous but essentially straight, one side distinctly longer than other. All body regions and pereomeres distinctly segmented. Head broad, weakly produced with strong anterior lamina equal to half length of head (Fig. 1A). Eyes absent. Antenna and antennule of three articles each (Fig. 2A). Maxilliped (Fig. 2B) with thin distally rounded spur; upper margin subovate with subdistal, broad, rounded, non-articulating palp and fringe of short setae. First oostegite proximal lobe ovate, distal lobe subtriangular, distally tapering and rounded, internal ridge smooth (Fig. 2C, D). Pereon composed of seven pereomeres, broadest across pereomere III, tapering anteriorly and posteriorly. Coxal plates well developed on longer side, clearly separated from pereomeres on I-V, indistinctly separate on VI and VII; elongateovate in shape on pereomeres I-III, narrowing and becoming longer on IV and V, tapering and bladelike on VI and VII. Dorsolateral bosses clearly demarcated and larger on longer side. Oostegites enclosing only approximately half of marsupium. Pereomeres II-VII with pronounced tergal projections on shorter side. Pereopods V- VII longer than I-IV (Fig. 2E, F). Outer margin of propodus, carpus, and merus with “serrate” region (acute scales along margin). Basis of all pereopods bearing pronounced rounded medial boss having scales on distal half. First pair of pereopods surrounding head region; pereopods I-V evenly spaced, VI and VII closely approximated. Pleon with five distinct pleomeres plus pleotelson; contours of all pleomeres sinuous (Fig. 1A). Pleomeres I-V with biramous pleopods and uniramous lateral plates; short side of body with lateral plates short and thin on pleomeres I-III, becoming shorter and rounded on IV and V; long side of body with lateral plates greatly elongated and bladelike on pleomeres I and II, thinner and shorter on III, short and rounded on IV and V; edges and surfaces of all lateral plates smooth; pleopodal exopodites and endopodites ovate and subequal with lightly tuberculate surfaces, all pairs proportionally longer on long side of body; pleopods only slightly decreasing in size posteriorly; uropods uniramous, slightly larger than, but similar in shape to lateral plates of pleomere V. A B Male (Figs 3; 4) Based on allotype. Length 2.14 mm, maximal width 1.05 mm, head length 0.23 mm, head width 0.60 mm, pleon length 0.38 mm. Head subovate, widest medially, distinct from first segment of pereon (Fig. 3A). Eyes absent. Antenna of three articles, distally setose; not extending beyond margin of cephalon; antennule of two articles; antennae and antennule with long thin setae on distal margins of segments (Fig. 4A). Pereomeres III-V broadest, tapering anteriorly and posteriorly. All pereomeres directed laterally, distolateral margins rounded. No detectable pigmentation. Pereopods (Fig. 4B, C) all subequal, all articles distinctly separated, palm of propodus with “serrate” region on surface and outer margin, outer margin and distal tip of carpus with long thin setae. Pleon with all five segments plus pleotelson fused into single segment, tapering posteriorly with sinuous margins and rounded tip. No midventral tubercles, pleopods or uropods. VARIATIONS The tergal projections on the pereon of the female are variable, sometimes being very indistinct; the frontal lamina is either smooth on the anterior margin or with a few faint indentations; the degree of closure of the marsupium is variable but never approaching fully closed; the medial region of the pleomeres is distinctly bulging dorsally in some specimens (probable artifact of preservation); and the shape of the anteriormost pleopods is variable from ovate to elongate-ovate, but never as tapered as those of A. kempi n. comb. (Chopra 1923: text-fig. 4a). The pleotelson of the male sometimes exhibits residual suture marks from pleomere fusion (Fig. 5); the lateral shape of the pereomeres varies from rounded to bluntly angled, but not acute or subacute. REMARKS Asymmetrorbione drepanopleon n. gen., n. sp. can be separated from its only congener, A. kempi n. comb., by numerous female characters such as the width of the anterior lamina of the cephalon (half of head length in A. drepanopleon n. gen., n. sp., less than half head length in A. kempi n. comb.), presence of eyes (only in A. kempi n. comb.), number of articles in the antenna (three in A. drepanopleon n. gen., n. sp., five in A. kempi n. comb.), scales on the maxilliped (only in A. kempi n. comb.), strong angle on the outer margin of the posterior lobe of the first oostegite (only in A. kempi n. comb.), coxal plates of pereomeres VI and VII distinctly longer and narrower than I-V (A. drepanopleon n. gen., n. sp.), tergal projections on pereomeres (A. drepanopleon n. gen., n. sp.), pleomeres indistinctly separated (A. kempi n. comb.) vs well separated (A. drepanopleon n. gen., n. sp.), lateral plates of pleomeres I-III on long side of body elongate ovate with rounded tips (A. kempi n. comb.) or lamellar and blade-like with acute tips (A. drepanopleon n. gen., n. sp.), pleopodal exopodites and endopodites lamellar (A. kempi n. comb.) or ovate (A. drepanopleon n. gen., n. sp.), and uropods nearly two times longer than lateral plates of pleomere V (A. kempi n. comb.) or subequal to lateral plates of pleomere V (A. drepanopleon n. gen., n. sp.). The males present only minor differences, such as the presence of eyes (only in A. kempi n. comb.) and the number of articles of the antennule (two in A. drepanopleon n. gen., n. sp., three in A. kempi n. comb.). Asymmetrorbione drepanopleon n. gen., n. sp. is also known from two different host species and at considerably greater depths than A. kempi n. comb.Published as part of Boyko, Christopher B., 2003, A new genus and species of bopyrid isopod (Crustacea, Isopoda, Bopyridae, Orbioninae) parasitic on Sicyonia (Crustacea, Decapoda, Penaeoidea) from New Caledonia, pp. 593-600 in Zoosystema 25 (4) on pages 595-599, DOI: 10.5281/zenodo.468952

REMARKS: Markham (1985a) transferred the type species of Paraphrixus, Phryxus subcaudalis Hay, 1917, to Eophrixus, synonymizing the two genera. However, Markham (1990, 1992a) continued to use the combination Paraphrixus brevicauda while admitting (1990) that “ Paraphrixus is no longer a valid name, but revision of the genus is not appropriate here.” It is clear that, based on current data, Hemiarthrus brevicauda must be placed in Eophrixus, as this is the genus with which it shares the most characters and, as a synonymized genus, it cannot be used as a valid name. Rediscovery of E. brevicauda is desirable in order to determine whether it really belongs in Eophrixus, as Chopra’ s (1923) description is incomplete and the type specimens are inaccessible.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 67, DOI: 10.1206/amnb-921-00-01.1, http://zenodo.org/record/461250
Concept FAITH as a value postulate of idiostyle V. S. Boyko
No full textСтаттю присвячено вивченню концепту ВІРА в мовосвіті В. С. Бойка як відомого майстра поетичного слова. Проаналізовано структуру концепту. Виокремлено ядрову, приядрову та периферійну зони. Описано художньо-семантичні наповнення мікроконцептів. Визначено авторську позицію щодо існування особистості у світі, а також індивідуально-авторські потрактування концепту ВІРА у мовомисленні митця.The article is devoted to the study of the concept of FAITH in the idiostyle of V. S. Boyko, as a famous master of the poetic word. The structure of the concept is analyzed. The nuclear, near-nuclear and peripheral zones are highlighted. The artistic and semantic content of micro- concepts is described. The author's position on the existence of a person in the world, as well as individual author's interpretations of the concept of FAITH in the idiostyle of the artist of the poetic word are determined. Whatever paths humanity has taken, this path has always been accompanied by faith. No matter what historical epoch we are talking about, no matter what country we talk about, it is difficult to disagree with the fact that faith has greatly influenced and is influencing the lives of millions of people. And it is not only about faith in higher powers, but also faith in a happy future, faith in yourself, in your people, in the triumph of moral values and the victory of good over evil. Faith is an important spiritual existential value that encourages a person to move on. Accordingly, the study of the linguistic expression of the concept of FAITH will allow to penetrate deeper into the peculiarities of individual language thinking, to determine the author's priority guidelines. Linguistic expression of the concept of FAITH in the poetic linguistics of V. S. Boyko finds in the words faith, to believe, prayer, icon, angel, orthodox, catholic, pagan, saint, temple, church, resurrection, apostle, paradise, cross, mantis, as well as in names of Оrthodox holidays and biblical names, because for the poet is close to the Christian, Orthodox worldview. The poetic picture of the artist's world is broader than dictionary interpretations, so the concept of FAITH acquires a broader artistic and semantic content

O. Sars, 1871, <i>Hemilamprops cristatus</i> (G. O. Sars, 1870) (Hansen 1916).</p> <p> <b>Remarks:</b> Nierstrasz & Brender à Brandis (1931) noted similarities between the females of the nebaliacean parasite <i>Apocumoechus paranebaliae</i> Nierstrasz & Brender à Brandis, 1931 and <i>Cumoechus insignis</i> Hansen, 1916 and placed both species in Cabiropidae, although with hesitation and noting that the cabiropids represented a heterogenous grouping. Danforth (1970) proposed a new subfamily of Cryptoniscidae, Apocumoechinae, to contain the nebaliacean parasite and another new subfamily, Cumoniscinae, to include <i>Cumoniscus</i> Bonnier, 1903 and <i>Cumoechus</i>; this work was not published (i.e., not recognized by the ICZN) and there were no characters provided to differentiate these taxa. These subfamily names were also mentioned by Adkison (1990) in his unpublished dissertation. Trilles (1999) placed <i>Cumoechus</i> in Apocumoechinae without comment and, again, provided no characters to differentiate Apocumoechinae from other taxa. Trilles (1999) also mentioned Cumoniscinae but it appears that he considered it to be a synonym of Apocumoechinae. Although Apocumoechinae has never been made available, Cumoniscidae is an available name from Nierstrasz & Brender à Brandis (1923; see Boyko & Boxshall 2018) but the type genus <i>Cumoniscus</i> is a tantulocaridan, not an epicaridean, and <i>Cumoechus</i> does not belong to this family.</p> <p> It is clear from the characters of the females, cryptoniscus larvae/males, and epicaridium larvae of <i>Cumoechus insignis</i>, that this genus and species does not belong in Cabiropidae (see Boyko 2013). We consider the characters of <i>C</i>. <i>insignis</i>, in particular those of the cryptoniscus larva, to indicate that this genus and species belongs in its own family, Cumoechidae <b>n. fam.</b></p> <p> The female of <i>C</i>. <i>insignis</i> is superficially similar to that seen in species of <i>Clypeoniscus</i> Giard & Bonnier, 1895 (Cabiropidae), particularly in the structure of the appendages: compare Hansen (1916: pl. 16, fig 5b, herein Fig. 4J) with Giard & Bonnier (1895: pl. 8, fig 22), but there are no lateral lobes in <i>C</i>. <i>insignis</i> (Hansen 1916: pl. 16, fig 5a). The cryptoniscus larva of <i>C</i>. <i>insignis</i> (slender body, elongate antennule basal segment, antennule peduncular segment 2 with large distal teeth, pereopods 1–3 prehensile, uropodal exopod and endopod slender and elongate; see Hansen 1916: pl. 16, fig 5c, e, f, i) is very different from that seen in species of <i>Clypeoniscus</i> (short, tear-drop shaped body, short antennular basal segment, antennule peduncular segment 2 without large distal teeth, pereopods 1, 2 prehensile, uropodal exopod and endopod stout and short). Likewise, the epicaridium larvae are different, with those of <i>Cumoechus insignis</i> (Hansen 1916: pl. 16, fig 5k) having the antennules as long as the body and setae on the antennules and uropods that are as long as or longer than the length of the body while the antennules, antennular setae, and uropodal setae of <i>Clypeoniscus</i> species are much shorter than the body.</p> <p> The unusual epicaridium larva of <i>Cumoechus insignis</i> superficially resembles that of <i>Scalpelloniscus vomicus</i> Hosie, 2008 (Hemioniscidae) as both have antennules, antennular setae and uropodal setae that exceed the length of the body. However, the seta on the distolateral corner of the uropodal sympod is shorter than the exopod in <i>C</i>. <i>insignis</i> and the anal tube is much shorter than the exopod while the epicaridium larva of <i>S</i>. <i>vomicus</i> have setae on the sympod that are more than three times as long as the exopod and the anal tube is as long as the exopod.</p> <p> The female of <i>Apocumoechus paranebaliae</i> is much less well described than that of <i>C</i>. <i>insignis</i> and no larval stages are known. From the limited data presented by Nierstrasz & Brender à Brandis (1931), it appears that <i>Apocumoechus</i> may be closer to <i>Clypeoniscus</i> than to <i>Cumoechus</i> but new collections and redescription of the type species are needed.</p> <p> Hansen (1916) figured specimens from three different collections and two different host species. Nielsen & Str̂mberg (1965) indicated the specimens (all syntypes) of <i>Cumoechus insignis</i> from the three different hosts might not “all belong to the same species” but this was speculative as they examined no specimens.</p>Published as part of <i>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)</i> on pages 260-261, DOI: 10.11646/zootaxa.5258.3.1, <a href="http://zenodo.org/record/7780211">http://zenodo.org/record/7780211</a>

Of these species, only <i>C. cumacei</i> was described based on a male associated with a female; all others are known only from the cryptoniscus larval stage collected in plankton samples. Cryptoniscus larvae/males of these species are characterized by their inflated heads (Fig. 4A), antennules (Fig. 4B), and pereopod morphologies (Fig. 4C–E), a unique combination of characters within Cryptoniscoidea; thus, the new family Capitoniscidae is herein erected for these two genera that were previously placed as Cryptoniscoidea <i>incertae sedis</i>. <i>Capitoniscus peruvicus</i> <b>n. comb.</b> was very incompletely described and figured but is clearly congeneric with <i>C</i>. <i>cumacei</i> and <i>C</i>. <i>australis</i>, albeit that <i>C</i>. <i>peruvicus</i> n. comb. has the most inflated head of all these species (Fig. 4F).</p> <p> The species of <i>Capitoniscus</i> and <i>Carocryptus</i> can be distinguished by the following characters of the cryptoniscus larvae: coxal plates not visible in dorsal view (<i>Capitoniscus</i>; Fig. 4A) vs. visible in dorsal view (<i>Carocryptus</i>; Fig. 4G) and pleotelson distal margin with few blunt teeth (<i>Capitoniscus</i>; Fig. 4H) vs. smooth (<i>Carocryptus</i>; Fig. 4G). The female of <i>C</i>. <i>cumacei</i> (Fig. 4I) was incompletely described and figured due to the specimen being lost after a preliminary sketch was made (Bourdon 1972).</p>Published as part of <i>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)</i> on page 260, DOI: 10.11646/zootaxa.5258.3.1, <a href="http://zenodo.org/record/7780211">http://zenodo.org/record/7780211</a>
Claustrathelges macdermotti Williams & Boyko, 2015, n. sp.
No full textClaustrathelges macdermotti n. sp. (Fig. 4) Material examined. Australia: Mature holotype female (14.4 mm) (MV J62893), infesting Cancellus typus (fide label), inhabiting stone, San Remo Channel, Victoria, 38°32’S 145°23’E, coll. I. Kirwan, March 1978. Description. Female (Fig. 4): Holotype body length 14.4 mm, maximal width 8.2 mm, head length 2.7 mm, head width 2.6 mm, pleon length 4.1 mm. Body longer than broad; pereon not distorted. All body regions and pereomeres distinctly segmented (Fig. 4A, B). Head length and breadth subequal with nearly straight lateral margins, anterior margin slightly convex, posterior margin convex. Eyes lacking. Antennule (Fig. 4C) of three articles, setae on distal margin of distalmost two segments; antenna (Fig. 4C) of five articles, setae on distal margins of distalmost three segments. Maxilliped (Fig. 4G) with rounded anterior lobe, palp absent; posterior lobe subtriangular with short rounded spur. Barbula (Fig. 4D) of three lobes with highly digitate margins on each side. Pereon of seven pereomeres, broadest across pereomere IV, tapering anteriorly and posteriorly. Pereomeres I–IV anteriorly concave and posteriorly convex, pereomere V nearly straight, pereomeres VI, VII anterior margin convex, posterior margin concave. No oostegites extended over head or produced posteriorly (Fig. 4A, B). Oostegites completely enclosing brood pouch (Fig. 4A); posteriormost oostegite with fringe of setae on posterior margin. First oostegite anterior lobe irregularly ovate with edges folded under, dorsal surface with medial region of ridges, posterior lobe with large ovate expansion and smaller, slightly tapering mesial extension, internal ridge with numerous digitations and larger digitate mesial lobe (Fig. 4E, F). All pereopods subequal, with all segments distinct (Fig. 4B, I, J). Pereopod I anterior to head, pereopods II,III parallel to head, no large gaps between pereomeres. Pleon with five pleomeres, dorsal segmentation distinct. Pleomeres I–V (Fig. 4A, B, K) with elongate-ovate biramous pleopods and uniramous lateral plates, all arising from common peduncle; pleotelson lacking (Fig. 4K). Male: unknown. Type locality. San Remo Channel, Victoria, Australia. Etymology. This species is named in honor of John J. McDermott (Emeritus Professor of Biology, Franklin and Marshall College, Pennsylvania, U.S.A.) for his considerable contributions to the biology and systematics of numerous marine invertebrates, including bopyrids. The specific name is spelled to conform to the ICZN Recommendations on the Formation of Names, Appendix D 21(a) (ICZN 1985: 197). Due to the necessity of synonymising the species we had earlier named for him, Pseudostegias macdermotti, in this paper, we felt it only fair to name a new species after him to make up for it. The taxonomist giveth and the taxonomist taketh away. Distribution. Known only from the San Remo Channel, Victoria, Australia. Host. Diogenidae: Cancellus typus. Size Range (Length). Females: to 14.0 mm, males: unknown. Remarks. The new species can be distinguished from its closest relatives in Falsanathelges by the characters given in the generic diagnosis. Cancellus hermit crabs were previously not known to bear any bopyrids. These hermits have an unusual choice of carcinoecia in that they are typically found living in calcareous rock, pumice, and other stones (McLaughlin, 2008). These habitats would appear to be a relatively difficult type for abdominal bopyrids in regards to the high potential for scraping against the rough surface of the carcinoecia when the hermit crab abdomen is flexed.Published as part of Williams, Jason D. & Boyko, Christopher B., 2015, Abdominal bopyrid parasites (Crustacea: Isopoda: Bopyridae: Athelginae) of diogenid hermit crabs from the western Pacific, with descriptions of a new genus and four new species, pp. 33-69 in Raffles Bulletin of Zoology 64 on pages 43-4
