The present study tries to focus on describing two new species belonging to genus Gammarus from western Iran along the Zagros Mountains range. The most remarkable feature of Gammarus hegmatanensis sp. n. is the shape of epimeral plate 3, which is sharply pointed posteriorly with a distinct lobate anterior margin. This species has some similarities with and differences from some other species of Gammarus pulex–group such as G. parthicus and G. syriacus. The other species, G. sirvannus sp. n. with elongated eyes is similar to G. duebeni, G. lobifer, G. balutchi and G. loeffleri, but it shows prominent morphological differences and a distinct geographical distribution from these species. These new findings shed more light on the information available on amphipod fauna of Iran.

Twenty six species of Scaphopoda, included in 12 genera and five families were identified. Within these, Fustiaria stenoschiza (Pilsbry & Sharp, 1897), Gadila pocula n.comb. (Dall, 1889); G. simpsoni n.comb. (Henderson, 1920) and G. pandionis (Verril & Smith in Verril, 1880) are recorded for the first time for Brazil and two new species of the genus Cadulus are here described. Besides that, six species previously recorded from north and northeast Brazil have their geographical range expanded southward: Antalis circumcincta (Watson, 1879), Episiphon didymum (Watson, 1879), Ep. sowerbyi (Guilding, 1834), Entalina platamodes (Watson, 1879), Gadila dominguensis (Orbigny, 1853) and Compressidens pressum (Pilsbry & Sharp, 1897). In the other hand, Paradentalium infractum n.comb. (Odhner, 1931) has its geographical distribution extended northward to the state of Maranhão (02ºS). Gadila acus (Dall, 1889) is proposed as junior synonym of G. dominguensis (Orbigny, 1853).

Two new morphospecies of the rotifer genus Testudinella (Rotifera, Monogononta, Testudinellidae), T. bicorniculata sp. nov. and T. elongata sp. nov., are described from marine psammon collected in the Mediterranean. T. bicorniculata sp. nov. is characterized by two antero-lateral lorica projections; dorsal and ventral anterior margins undulate with shallow median sinus; foot opening sub-terminal, inverted U-shaped; distal foot pseudosegment short; fulcrum with proximal opening. T. elongata sp. nov. is characterized by its strongly elongate and striate lorica; dorsal anterior margin tri-lobed; ventral margin projecting, almost straight; foot opening sub-terminal, inverted U-shaped; distal foot pseudosegment long; fulcrum with proximal opening. The new species are related to T. obscura Althaus, 1957, which is redescribed. Brief descriptions of the external morphology and trophi, as well as biogeographical information are provided for the other Testudinella species reported from marine and brackish environments. T. pseudoclypeata Bērziņš, 1943 is synonymized with T. elliptica (Ehrenberg, 1834).

Two new species of Aricidea Webster, 1879 (Paraonidae), Aricidea (Acmira) anusakdiisp. nov. and Aricidea (Aricidea) thammapinanaesp. nov. were collected from 10–26.5 m depth, in soft bottoms with mud mixed with sand and shells at Songkhla Sea, the Gulf of Thailand between 2011–2018. Aricidea (Acmira) anusakdiisp. nov. is clearly distinguished from other species of the subgenus Acmira by having a rounded bilobed prostomium divided by a slight notch on the anterior margin; red pigments on the subdistal to the tip of each branchia (new character); two prebranchial chaetigers; 48–68 pairs of branchiae; and modified neurochaetae as strong curved spines with blunt shafts surrounded by pubescence from chaetigers 19–44. On the other hand, Aricidea (Aricidea) thammapinanaesp. nov. can be separated from other members of the subgenus Aricidea by the presence of a biarticulated median antenna; distinctive notopodial lobes as broad triangular with short distal protuberances on chaetiger 3, 4–8 pairs of branchiae; and modified neurochaetae as bidentate neurochaetae with a long pubescent subterminal arista on the concave side.

AbstractRamalina europaeaGasparyan, Sipman & Lücking andR. labiosorediataGasparyan, Sipman & Lücking, two species of theR. pollinariagroup, are described here as new to science.Ramalina europaea, widely distributed in Europe, can be distinguished by small, punctiform, often terminal soralia starting out on small, spine-like branchlets, whereasR. labiosorediatafrom North America differs fromR. pollinarias. str. andR. europaeain the almost exclusively terminal soralia formed on the tips of normal lobes, originating from the underside and becoming irregularly labriform. Morphological characters, chemistry, ecology and geographical distribution are discussed and a key to the species of theRamalina pollinariagroup is provided. The topology of a maximum likelihood tree based on ITS shows the presence of three well-supported clades, corresponding to the morphological differences of the three species. The status of several historical names variously placed in synonymy with or described as infraspecific entities ofR. pollinariais reassessed and a new neotype and an epitype are designated forLichen pollinarius, a neotype forL. squarrosus, making it a synonym ofR. farinacea, and lectotypes forR. pollinariavar.elatior, making it a synonym ofR. pollinarias. str., and for var.humilis, a taxon of yet unknown affinity.

Species Descriptions

Phytophthora Clade 5 is a very poorly studied group of species of oomycete chromists, consisting of only two known species P. castaneae (≡ P. katsurae, nom. illegit.) and P. heveae with most isolates from East Asia and the Pacific Islands. However, isolates of two important disease-causing chromists in Clade 5, one of kauri (Agathis australis) in New Zealand, the other of coconut (Cocos nucifera) in Hawaii, poorly match the current species descriptions. To verify whether these isolates belong to separate species a detailed morphological study and phylogenetic analysis consisting of eight genetic loci was conducted. On the basis of genetic and morphological differences and host specificity, we present the formal description of two new species in Clade 5, Phytophthora agathidicida sp. nov. and Phytophthora cocois sp. nov. To clarify the typification of the other Clade 5 species, an authentic ex-holotype culture of Phytophthora castaneae is designated and P. heveae is lectotypified and epitypified.

Two New Species

Two new species of Grandidierella Coutière, 1904 from Singapore waters are described based on specimens collected during the Comprehensive Marine Biodiversity Survey (CMBS) between 2010–2015. Grandidierella pawaiensis sp. nov. differs from the rest in the genus by a combination of characters; (1) gnathopod 1 carpus proximoventral corner with apically acute process, (2) inner face of carpus of gnathopod 1 proximoventral corner with curved process, (3) proximal margin of dactylus of gnathopod 1 male with excavation, and (4) gnathopod 2 basis anterior margin crenulate. Grandidierella sungeicina sp. nov. on the other hand, is distinguishable from other related species of Grandidierella found in the tropical region by its paired mid-dorsal projections on pereonites 2 to 5, 1 ventrodistal triangular projection on pereonite 4, and gnathopod 2 ischium with 1 large trapezoid projection.

Unidentified Species

The species herein described both belong to the family Menoponidae. One of these species, collected by me from a Waxbill (a passerine bird) at Onderstepoort, Pretoria, belongs to the genus Machaerilaemus Harrison, the other, taken from a Sandgrouse in the Rustenburg District, Transvaal, by Mr Powell, together with specimens of a species of Degeeriella, I am placing in a new genus, for which I propose the name Neomenopon. These two new species are extremely interesting, in that they both possess a chitinous framework extending backwards from the anterior margin of the head for the support of the mandibles, a structure previously only known to occur in the genus Eomenopon Harrison, which was established partly on account of this structure. A similar structure, however, also occurs in a small unidentified species of Menopon taken from a Little Banded Goshawk (Astur polyzonoides) at Onderstepoort. This species may eventually prove to be sufficiently distinct in other details from the type of Menopon to warrant the founding of a new genus for its reception.

Two new species of Pentacalia are described herein on the basis of morphological evidence. These new findings are the result of field work and recent herbarium studies carried out at USM. Both species are very distinctive and any confusion with the other known taxa of the genus is unlikely. Both species are hitherto only known from the type locality, one collected in Junín Department (central Peru) and the other in Amazonas Department (northern Peru). They grow in Andean humid montane forests. Pictures of the respective holotypes and a distribution map are provided. Moreover, the name P. marinii is synonymized under P. herzogii, as well as P. megaphlebia to P. oronocensis.

More than ten new species of colonial volvocine algae were described in world literature during recent years. In present review, the published data on taxonomy, geographical distribution and the species problem in this group of algae, mainly from the genera Gonium, Pandorina, Eudorina, and Volvox, are critically discussed. There are both cosmopolitan volvocalean species and species with local or disjunct distribution. On the other hand, the description of new cryptic taxa in some genera of the colonial family Volvocaceae, such as Pandorina and Volvox, complicates the preparation of a comprehensive review on their geography.

Two new species of Terebrasabella Fitzhugh & Rouse, 1999 are described from eastern Australia. Terebrasabella hutchingsae sp. nov., was found from preserved coral rock debris collected in 1977 on the outer Barrier Reef near Lizard Island, Queensland. Terebrasabella fitzhughi sp. nov., was found alive in burrows in and among spirorbin serpulid tubes on intertidal rocks in Tasmania in 1996. Both species were found in mucoid tubes, and brood their young in a manner similar to the only other described species of Terebrasabella, T. heterouncinata Fitzhugh & Rouse, 1999. Terebrasabella hutchingsae sp. nov., is exceptional as it possesses a type of thoracic neurochaetal uncinus different from the other two species, and which is similar to the notochaetal acicular “palmate hook” seen in Caobangia. Descriptions of both species are given, and the diagnosis for Terebrasabella is emended. Larval and chaetal morphology and relationships among of the three known Terebrasabella spp. are discussed.
