We report the occurrence of the genus Bicorniphontodes George, Glatzel & Schröder, 2019 in Korean waters, with descriptions of three new species: Bicorniphontodes lacuna sp. nov., B. comptus sp. nov., and B. huysi sp. nov. Morphology analysis was carried out to reconstruct the phylogenetic relationships of Bicorniphontodes species, including the three new species. Parsimony analysis based on 41 characters revealed that the three new species are clustered together as a monophyletic clade, of which B. horstgeorgei (George & Gheerardyn, 2015) is a sister species. The monophyletic status of three new species was supported by five synapomorphies, such as the micro-morphological conditions of the exopodal segments of the first leg, coxae of the second to fourth legs, exopod of the fifth leg in the female and baseoendopod of the fifth leg in the male, and the maxillular endopod represented by two setae. These three species can be easily distinguished based on the morphology of the rostrum, cephalothoracic processes, female genital double-somite, caudal rami, and second endopodal segment of the third leg in the male. The taxonomic position of B. bicornis sensu Kim, 2013 in Korean fauna was reevaluated based on the newly collected material from Udo Islet near Jeju Island; this resulted in a synonym of B. huysi sp. nov.

A New Species

A new species of Amanita sect. Roanokenses, A. brunneofolia, from South Korea, is described based on morphological and molecular evidences. The species is characterized by medium- to large-sized basidiomata, a greenish white pileus covered with brownish, floccose pyramidal volval remnants, an appendiculate margin, reddish brown lamellae, a long radicating stipe, and ellipsoid to elongate amyloid basidiospores. Based on both nrLSU and combined dataset (nrLSU, rpb2 and tef1-α), A. brunneofolia formed a monophyletic clade and clearly separated from other Amanita species. In addition, we describe two other Amanita species in A. sect. Roanokenses, namely, A. caojizong and A. sphaerobulbosa. This is the first report of these species for South Korea.

Herein two new species of the genusSyngastesMonard, 1924 are described from South Korea, with detailed descriptions and illustrations. Both new copepods,Syngastesmulticavussp. nov. andS. pseudofoveatussp. nov., have two inner setae on the first exopodal segment of P2 and P3.Syngastesmulticavussp. nov. most closely resemblesS. gibbosusBartsch, 1999 reported from Australia, as they both have a five-segmented antennule in the female. However,Syngastesmulticavussp. nov. has a rounded body outline instead of the gibbose outline observed inS. gibbosus.Syngastespseudofoveatussp. nov. resemblesS. foveatusBartsch, 1994 in almost all aspects. However, they differ clearly in the number of setae on the first exopodal segment of P2 and P3. We also provide a key to species of the genusSyngastesworldwide. The present study is the first record of the family Tegastidae in Korean waters.

Three New Species

A consultation of the original descriptions of the genera of Scissurellidae led the author to conclude that the valid names for the genera of this family are: Scissurella d'Orbigny, 1823 (redescription by Sowerby, 1824), Anatoma Woodward, 1859, Inoisura Hedley, 1904, Scissurona Iredale, 1924, Sinezona Finlay, 1927. Scissurella and Anatoma are cosmopolites, the first generally living in shallow waters, associated to sea-weeds, while the second is found in deep waters. The three last genera are restricted to Australasia. Three new species are described from the Brazilian coast: Soissu rella alexandrei, Scissurella eleotilis and Scissurella morretesi. The internal anatomy of S. alexandrei is described. These three new species have been found in littoral shallow waters, the two first on the northeast Brazilian coast, the third on the coast of the State of São Paulo. The fourth known species of Scissurellidae from Brazil, Anatoma aedonia (Watson, 1886), was dredged by H.M.S, "Challenger", in 1873, off Pernambuco, 350 fm (640 m).

A New Species

A new species of the continental shelf hyperbenthic genus Pilarella is described, the first from the Indo-Pacific. This is the second species of Pilarella known, and the first description of a male in the genus. The new species is easily distinguished from other species of Pilarella (P. longicornis) based on: (1) short caudal rami, approximately 1.5 times longer than wide; (2) 2 setae on the mandibular endopod; (3) 6 setae on the maxillular coxal epipodite; and (4) in the female, a short left antennule reaching the posterior border of the genital double-somite. The new diagnosis of Pilarella differs from Metacalanus in the separation of ancestral segments IX–XII and XIV–XV of the antennule, and the presence of 5–6 setae on the maxillular praecoxal arthrite. Pilarella is also separated from Metacalanalis based on the absence of a seta on the third ancestral segment of the antennary exopod, the symmetry of legs 1–3, the presence of a medial basal seta on the female leg 5, and 2 lateral exopodal spines on the female leg 5. A molecular phylogenetic analysis of some representative genera of the family Arietellidae, including the present new species, recovers two arietellid clades (Metacalanus- and Arietellus-clades) as in previous studies. Dichotomous keys for the genera of Arietellidae and the species of Pilarella are included.

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.

AbstractThree new species of snapping shrimps of the genusAlpheusare described from the Persian Gulf. These belong to theAlpheus edwardsiispecies-group, which is mainly characterized by unarmed orbital hoods and the presence of dorsal and ventral notches on the palm of the major chela.Alphus ankerisp. nov. shows a close affinity toA. pacificusDana, 1852 andA. heronicusBanner & Banner, 1982 bearing no balaeniceps crests in both sexes on the dactylus of the minor chela, and the merus of the major chela of both sexes are unarmed. This species differs from the closely related species by the absence of an overhanging proximal shoulder in the major chela. The other rock crevice inhabiting species,A. mohammadpourisp. nov. is diagnosed by exhibiting sexual dimorphism in its balaeniceps crests and the armed merus of the major chela. These two characters are similar to those recorded for three sandy/rubble dwelling species:A. inopinatusHolthuis & Gottlieb, 1958,A. lobidensDe Haan, 1849 andA. australiensisBanner & Banner, 1982. This new species is distinguishable from these latter species by the shape of the minor chela and colour pattern. A coral inhabiting speciesA. abumusasp. nov. appears to be closely related toA. maindroniCoutière, 1898, showing an armed merus of the major chela and the absence of spine-like seta on the ischia of the third legs. This last new species is easily discriminated fromA. maindroniby longer antennular segments, a markedly concave frontal margin between the rostrum and orbital hood, and a different colour pattern.

Three New Species

Three annual Diascia species are described from the western Cape. Two species, D maculata K.E. Steiner and D. humilis K.E. Steiner have small flowers and are closely related.  D. maculata is characterized by a slightly gibbous corolla with no spurs or sacs, erect stamens, and a distinct patch of oil-secreting trichomes in the tube at the base of each upper and lateral corolla lobe. D. humilis is characterized by a bisaccate corolla, forward projecting stamens and oil-secreting trichomes localized in corolla sacs. The third new species,  D hexensis K.E. Steiner, is most similar to D. sacculata Benth.. but it differs from that species by its larger flowers and much longer spurs which curve downward instead of upward.
