Twenty-six species of endogean beetles are recorded from the Marganai-Oridda-Valle del Leni area, belonging to six different families: Carabidae (Typhloreicheia holdhausi Magrini, Fancello & Casale, 2006, T. leoi pilosa Magrini & Fancello, 2007, T. tanit Leo, Magrini & Fancello, 2005), Leiodidae [Bathysciola damryi (Abeille de Perrin, 1881)], Staphylinidae [Eudesis aglena Reitter, 1882, E. minima Binaghi, 1948, Mayetia sp., Trimium amplipenne Reitter, 1908, Tychobythinus dentimanus (Reitter, 1884), Tychus sp., Pselaphostomus sp., Phloeocharis ichnusae Dodero, 1900, Octavius raymondi Saulcy, 1878, O. sardous Coiffait, 1965, four new species of Entomoculia, three new species of Leptotyphlus], Zopheridae (Langelandia reitteri Belon, 1882, Lyreus septemstriatus Fancello & Leo, 1991), Curculionidae (Torneuma sp.) and Raymondionymidae [Alaocyba carinulata Perris, 1869, Raymondiellus sardous sardous (Perris, 1869)]. One species (Langelandia reitteri) is W-Mediterranan, one is a Sardo-Corsican endemic (Tychobythinus dentimanus), the remaining 24 species are all Sardinian endemics and 16 of these are strictly localized within the study area or restricted to SW Sardinia. The following species of Staphylinidae Leptotyphlinae are described: Entomoculia villascemae sp. nov., E. carbonaria sp. nov., E. shardana sp. nov., E. melonii sp. nov., Leptotyphlus nardii sp. nov., L. minator sp. nov. and L. villacidrinus sp. nov.; all are easily distinguishable from their congeners by the structure of the male copulatory organ and female genital armature. The morphology of the copulatory organ in the newly described Leptotyphlus species indicates that the classical subgeneric categories used in Leptotyphlus are probably based on characters not reflecting a natural subdivision of the genus.

The present study reports three new species of Ostracoda, Loxoconcha damensis sp. nov., Xestoleberis vietnamensis sp. nov. and X. munensis sp. nov., from Phu Quoc Island, southwest Vietnam and Nha Trang Bay, central Vietnam. These species inhabit the coral reefs around isolated islands and can be easily distinguished from other known species based on their morphological differences, mainly in the male copulatory organ. Loxoconcha damensis sp. nov. belongs to Loxoconcha Group A, based on the distributional pattern of their pore system below the eye tubercle. Similarly, based on a combination of morphological types of pore systems, the two new Xestoleberis species belong to Xestoleberis Group A, because these species have two types of pore systems, i.e., sieve-type and lip-type. To the best of our knowledge, this study is the first report on Xestoleberididae and the second on Loxoconchidae from the Recent of Vietnam.

Neodiplectanum Mizelle & Blatz, 1941 is resurrected and emended for monogenoids from the gills of gerreid hosts from Western Atlantic: Neodiplectanum wenningeri from Eucinostomus gula (Quoy & Gaimard) [type-host] and Gerres cireneus (Walbaum); N. magnodiscatum (Fuentes Zambrano, 1997) n. comb. (syn. Diplectanum magnodiscatum Fuentes Zambrano, 1997) from Eugerres plumieri (Cuvier); Neodiplectanum gatunense (Mendoza Franco, Roche & Torchin, 2008) n. comb. (syn. D. gatunense Mendoza Franco, Roche & Torchin, 2008) from Eugerres brasilianus (Cuvier); N. mexicanum (Mendoza Franco, Roche & Torchin, 2008) n. comb. (syn. D. mexicanum Mendoza Franco, Roche & Torchin, 2008) from Diapterus rhombeus (Cuvier). Neodiplectanum is characterized for diplectanids with male copulatory organ and accessory piece non-articulated, heavily sclerotised vaginal atrium, ventral anchors with deep root twice as long as superficial root, dorsal anchors with conspicuous superficial and deep roots and squamodiscs with spinelike rodlets in the posterior rows. Darwinoplectanum n. gen. is proposed for species with male copulatory organ articulated to the accessory piece, vaginal opening sinistral, marginal or submarginal; non-sclerotised vagina atrium; and egg ovate with short filament. Here, we described three new species of Darwinoplectanum n. gen. from the gills of gerreid hosts from the Eastern and/or Western Atlantic: Darwinoplectanum figueiredoi n. gen. n. sp. [type species] from Eucinostomus argenteus Baird & Girard; D. amphiatlanticus n. gen. n. sp. from Eucinostomus melanopterus (Bleecker)[Type host] from Africa, and E. argenteus from Brazil; and D. pilittae n. gen. n. sp. from G. cireneus.

Three New Species

Three new species of Urocleidoides Mizelle & Price, 1964 are described from the gills of characiform fishes in the Tocantins River and its tributaries. Urocleidoides boulengerellae sp. nov. is described from Boulengerella cuvieri (Spix & Agassiz, 1829) and differs from all its congeners by the dorsal bar with a long posteromedial projection; male copulatory organ with 2–3 counterclockwise rings and a base with a flange; an accessory piece comprising a robust Y-shaped unit and a sheath-like unit; and a highly sclerotized vaginal canal. Urocleidoides paratriangulus sp. nov., described from Psectrogaster amazonica Eigenmann & Eigenmann, 1889, Cyphocharax gouldingi Vari, 1992, Caenotropus labyrinthicus (Kner, 1858) and Mylesinus paucisquamatus Jégu & Santos, 1988, is most similar to Urocleidoides triangulus (Suriano, 1981) Rossin & Timi, 2016 based on the shape of the anchors and bars but differs from U. triangulus in the morphology of the projection of the dorsal bar, the number of rings of male copulatory organ, and by the smaller size of members of hook pairs 1 and 5 compared with those of the remaining pairs. Urocleidoides tocantinensis sp. nov. is easily distinguished from all other species of the genus by the morphology of the vagina, which present a vaginal vestibule with a membranous cap. Urocleidoides triangulus is reported from its type host in the Guandu River, state of Rio de Janeiro. The present study increases the number of Urocleidoides species to 37 recognized species that fit all the generic characters.

During general field surveys carried out recently to collect benthopelagic copepods from near the substrate of the shallow waters off Jeju Island, Korea, a few specimens of three new species of Stephos Scott, 1892, were collected. The new species are placed in the genus Stephos because of the following combination of features: absence of seta on the basal exite of maxillule, and male right leg 5 ending in an unarmed claw-like and/or mitten-like segment. Stephos jejuensissp. nov. can be distinguished from its congeners by body length 0.92 mm, left side of the female genital double-somite with protruding lobes, antennule that extends beyond the distal area of the genital double-somite, and the male leg 5 terminal complex. Stephos concavussp. nov. can be distinguished from its congeners by the genital double-somite with protruding lobes on both sides, and the presence of larger spinules on the distomedial margin of leg 5. Stephos fortipessp. nov. can be distinguished from its congeners by its longer body length, 1.12 mm long in the female, antennules that extend to the end of the genital double-somite, and the presence of a covered row of minute spinules on the ventral surface of the genital operculum in the female. Until now, 35 species of stephids were known worldwide.

AbstractCalydiscoides limae sp. nov. is described from the nemipterid Pentapodus aureofasciatus Russell, 2001 caught along the barrier reef off New Caledonia, South Pacific. The new species is characterised by its male copulatory organ, with a distal blade and a lateral spur, and its female sclerotised organ, with a sphere and a thin tube. Its lamellodiscs always have 7 concentric lamellae, with the 3 internal lamellae complete and the 4 peripheral lamellae progressively less and less complete; measurements of the angles occupied by the lamellae in numerous specimens showed that the lamellodisc structure shows little variation among individuals.

Platycephalotrema n. gen. (Dactylogyridae) is proposed for four new species and 5 previously described species parasitizing the gills of flatheads (Scorpaeniformes: Platycephalidae) as follows: Platycephalotrema ogawai n. sp. (type species) from Platycephalus sp. 1 (type host) and Platycephalus sp. 2, both of Nakabo & Kai (2013) (locally known as “Yoshino-gochi” and “Ma-gochi,” respectively) (Japan); Platycephalotrema austrinum n. sp. from Platycephalus endrachtensis Quoy & Gaimard (type host) and Platycephalus sp. (Australia); Platycephalotrema bassensis (Hughes, 1928) n. comb. from Platycephalus bassensis Cuvier (Australia); Platycephalotrema koppa n. sp. from Platycephalus fuscus Cuvier (Australia); Platycephalotrema macassarensis (Yamaguti, 1963) n. comb. from Platycephalus indicus (Linnaeus) (China, Macassar); Platycephalotrema mastix n. sp. from P. fuscus and P. endrachtensis (Australia); Platycephalotrema platycephali (Yin & Sproston, 1948) n. comb. from P. indicus (China) and P. fuscus (Australia); Platycephalotrema sinensis (Yamaguti, 1963) n. comb. from Cociella punctata (Cuvier) (China); Platycephalotrema thysanophrydis (Yamaguti, 1937) n. comb. from Inegocia japonica (Cuvier), Inegocia ochiaii Imamura, and Cociella crocodilus (Cuvier) (Japan, China). Other species requiring further study but potentially members of Platycephalotrema include Ancyrocephalus vesiculosus Murray, 1931, Haliotrema indicum Tripathi, 1957, Haliotrema swatowensis Yao, Wang, Xia, & Chen, 1998, and Haliotrema pteroisi Paperna, 1972. The primary features differentiating Platycephalotrema include species having: (1) tandem gonads (testis postgermarial); (2) two prostatic reservoirs, each emptying independently into the base of the male copulatory organ; (3) a dextral vaginal pore and large vaginal vestibule; (4) dorsal and ventral pairs of morphologically similar anchors; (5) a ventral bar with spatulate ends; (6) a dorsal bar with bifurcated ends, and (7) absence of an accessory piece. The new species are described, and P. thysanophrydis is redescribed based on newly collected and museum specimens.

Three new species of Parasyrisca Schenkel, 1963 belonging to the potanini-group are described from Western Mongolia: P. platnicki sp. n., P. polchaninovae sp. n. and P. szinetari sp. n. Each species description is based on both sexes. Both the male and female of P. platnicki sp. n. possess some copulatory organ characters unknown in other species of the genus. The previously unknown female and the poorly known male of P. khubsugul Ovtsharenko, Platnick et Marusik, 1995 are described and redescribed respectively, the descriptions being based on the specimens found in Arkhangai and Bayankhongor Aimags. The structures of copulatory organs in Parasyrsca potanini-group are briefly discussed.

Urocleidoides spp. are reported from the gills of 20 specimens of Parodon nasus (standard length 8.5–12 cm), from the Indiana stream, Tietê River, Upper Paraná River basin, municipality of Botucatu, São Paulo State, Brazil. Urocleoidoides tenuis and two new species were found. Urocleidoides indianensis n. sp. differs from its congeners mainly by the morphology of the vaginal sclerite that is robust, sickle-shaped, and forked at the distal end; and by the bulbous-shaped accessory piece of the male copulatory complex. Urocleidoides parodoni n. sp. resembles U. tenuis by presenting male copulatory organ with approximately 7 ½ counterclockwise rings, but differs by the morphology of the accessory piece (lobate with a small hook-like projection versus pincer-shaped), vaginal sclerite (thumb-like subterminal projection vs. presence of a distal hook), vaginal tube (conspicuously sclerotized vs. slightly sclerotized), shape of the ventral bar (bowed vs. wide V-shaped), ventral and dorsal anchors (robust base and short shaft vs. considerably less robust base and long shaft), and hooks (slender shank with a weakly sclerotized subunit at base vs. dilated shank). Sequences of the partial 28S rDNA gene of the dactylogyrids found in this study are provided. Phylogenetic analyses showed Urocledoides spp. from Parodontidae clustering together with strong support values. This study increases the number of valid Urocleidoides species to 39, and the number of species described from parodontid hosts to four.

Two New Species

Two new species, Dendromonocotyle citrosa n. sp. off Dasyatis chrysonota (Smith) from Two Oceans Aquarium in Cape Town and off Himantura gerrardi (Gray) from uShaka Sea World in Durban and D. ukuthena n. sp. off H. gerrardi and H. uarnak (Forsskal) also from uShaka Sea World in Durban, are described. These can be distinguished from previously described Dendromonocotyle species by the morphology of the distal portion of the male copulatory organ and the proximal part of the vagina. Vaginal morphology is proposed as an important diagnostic character for species in the genus. Dendromonocotyle colorni Chisholm, Whittington & Kearn, 2001 which was originally recorded from H. uarnak in Israel, was discovered on H. uarnak sympatrically with D. ukuthena n. sp. and with D. citrosa n. sp. and D. ukuthena n. sp. off H. gerrardi. Minor differences in the number of papillary sclerites, the presence of septal tripartite sclerites and in the number of eyespots were seen between D. colorni collected from H. uarnak and H. gerrardi from uShaka Sea World and those originally described off H. uarnak from Israel. We demonstrate that the position of the marginal hooklets can be used to determine the orientation of the haptor of all representative Dendromonocotyle species with or without hamuli. We conclude that Dendromonocotyle species may not be as host-specific as previously believed and that minor differences in morphology are host or geographically induced.

Abstract A new species of Loimopapillosum Hargis, 1955 is described based on specimens collected from the gills of the diamond stingray, Hypanus dipterurus (Jordan & Gilbert, 1880) (Myliobatiformes: Dasyatidae) captured off Puerto Pizarro, Tumbes Region, northern Peru. Loimopapillosum pascuali n. sp. is distinguished mainly from the type and only species, Loimopapillosum dasyatis Hargis, 1955, by its funnel-shaped male copulatory organ, with an asymmetrical base; the superficial root of the anchor with distal knobs; the deep root of the anchor with a constriction at its base; a single testis; and the number of head organs. Available sequences for members of Monocotylidae in the GenBank as well as partial sequences for the gene 28S and 18S ribosomal DNA from L. pascuali n. sp. were included in phylogenetic analyses, suggesting that Loimoinae (represented in this study by L. pascuali n. sp. and Loimosina sp.) is nested within the Monocotylidae Taschenberg, 1879. Therefore, we confirm the rejection of Loimoidae Price, 1936 and its reincorporation as a subfamily of Monocotylidae, as previously suggested. Loimopapillosum pascuali n. sp. represents the first species of this genus in South America.
