Three New Species

Resuming published and own data, a revision of classification of Chaetognatha is presented. The family Sagittidae Claus & Grobben, 1905 is given a rank of subclass, Sagittiones, characterised, in particular, by the presence of two pairs of sac-like gelatinous structures or two pairs of fins. Besides the order Aphragmophora Tokioka, 1965, it contains the new order Biphragmosagittiformes ord. nov., which is a unique group of Chaetognatha with an unusual combination of morphological characters: the transverse muscles present in both the trunk and the tail sections of the body; the seminal vesicles simple, without internal complex compartments; the presence of two pairs of lateral fins. The only family assigned to the new order, Biphragmosagittidae fam. nov., contains two genera. Diagnoses of the two new genera, Biphragmosagitta gen. nov. (type species B. tarasovi sp. nov. and B. angusticephala sp. nov.) and Biphragmofastigata gen. nov. (type species B. fastigata sp. nov.), detailed descriptions and pictures of the three new species are presented.

Two Populations

Two new species of Austrolebias are described based on specimens collected from temporary pools located in natural grassland landscape within the Araucaria Forest domain at exceptionally high altitudes (~1000 meters a.s.l.). Austrolebias botocudo sp. n. and Austrolebias nubium sp. n. occur, respectively, in drainages of upper rio Apuaê-Inhandava (upper rio Uruguay basin) and upper rio Taquari-Antas (upper rio Jacuí, Laguna dos Patos basin), in the Meridional Plateau of southern Brazil. Despite an intensive survey conducted in the area, only two populations of each species were recorded. Both new species occurs at altitudes that are among the higher recorded for species of the genus, and both are assigned to the subgenus Acrolebias. The new species described herein are easily distinguished for its congeners by the colour pattern of males, by presence of melanophores irregularly distributed in different parts of the body, contact organs cover the body and anal fins, position of fins related with vertebrae, by preopercular and mandibular series of neuromasts united, by a series of morphometric features and by larger maximum standard length. Austrolebias botocudo and A. nubium are distinguished from each other by colour pattern of males, length of contact organs in the flank and number of contact organs in scales of lateral line, dorsal profile of head, number of neuromasts in the preopercular + mandibular series, body depth in females, and by basihyal cartilage length. Additionally, we discuss the conservation status of the new species, and provided an identification key for the species of the subgenus Acrolebias.

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.

Five new species of the genus Dichaetomyia are described from Madagascar as Dichaetomyia ambrea sp. n., Dichaetomyia besseta sp. n., Dichaetomyia doubla sp. n., Dichaetomyia montea sp. n., and Dichaetomyia ranoa sp. n. The body colour of the five species is shiny metallic blue, green or violet and the colour combinations are similar to Dichaetomyia tristis (Zielke, 1972). The species, however, differ significantly from one another in other taxonomic characteristics which are commonly used in other genera to distinguish species.

Three New Species

Three new species of Gastromyzon from Brunei Darussalam, on the island of Borneo, are described from recent collections and from older museum specimens. Gastromyzon cranbrooki, new species, is superficially similar to G. borneensis, but differs in having a distinct secondary rostrum; body brown with 9–10 grey bars, head dorsum dark brown with thin grey reticulate pattern; and 56–60 scales on lateral line. Gastromyzon aeroides, new species, is similar to G. punctulatus, but differs in having the body uniform brown, dorsum uniform brown; head dorsum with very fine cream reticulate pattern (similar to a cream head with brown spots and blotches); dorsal, caudal and anal fins blue in life; and 47–65 scales in lateral line. Gastromyzon venustus, new species, is similar to G. pariclavis, but differs in having both the body and head dorsum plain brown; dorsal, caudal and anal fins red in life; and 58–63 scales in lateral line.

By Catch

A new species of viviparous sea snake, Hydrophis donaldi sp. nov. (Hydrophiinae), is described from the Gulf of Carpen-taria, northern Australia. Molecular analyses reveal this species as a deeply divergent lineage within the Hydrophis sub-group, and separate it from all other sampled taxa by fixed nucleotide substitutions at three independent mitochondrial andnuclear loci. The new species is assigned to Hydrophis based on the current morphological diagnosis of this large but pa-raphyletic genus, and is distinguished from all other Hydrophis species and closely allied genera by a combination of mor-phological characters relating to scalation, colour pattern and osteology. Using current keys for sea snakes, H. donaldi sp.nov. might be mistaken for H. coggeri, H. sibauensis or H. torquatus diadema but it is readily distinguished from thesespecies by a higher number of bands on the body and tail, lower ventral count, strongly spinous body scales, and a wider,more rounded head. Sea snakes have been sampled intensively in the Gulf of Carpentaria due to their vulnerability to by-catch in the region’s commercial prawn-trawl fisheries. That this highly distinctive new species has evaded discovery inthe region until now is surprising, but might be explained by its habitat preferences. All known specimens of H. donaldi sp. nov. were found in estuarine habitats that are relatively poorly surveyed and are not targeted by commercial fisheries.

The author examined paratypes of Doryphoribius flavus (Iharos, 1966) (formerly Hypsibius (Isohypsibius) flavus Iharos, 1966), and the holotype and paratypes of D. citrinus (Maucci, 1972) (which is considered a junior synonym of D. flavus), furnishing new details, both qualitative and metric, to the description of the species, and providing a discussion on the synonymy. Specimens, previously attributed to these species, from Amazonia, South Africa, and Bali, were also examined and proved to belong to three species new to science: Doryphoribius amazzonicus sp. nov., Doryphoribius bindae sp. nov., and Doryphoribius solidunguis sp. nov. Doryphoribius amazzonicus sp. nov. has a reticular cuticular ornamentation with ridges forming a tubercle at each crossing; legs lacking cuticular ornamentation; buccal tube slightly longer than in D. flavus with respect to the body length, stylet supports inserted on the buccal tube in a slightly more caudal position; peribuccal papulae present; teeth and ridges appear to be absent in the buccal cavity; pharyngeal bulb with apophyses and two macroplacoids; claws slightly shorter and stouter than in D. flavus. Accessory points and smooth lunules present. No other cuticular thickening present on the legs. Doryphoribius bindae sp. nov. has a delicate reticular cuticular ornamentation formed by narrow ridges with a tiny tubercle at each crossing; a fine reticular design present on the legs; peribuccal papulae present, buccal armature with only one dorsal tooth near the medial margin of each stylet sheath. Pharyngeal bulb with apophyses and two macroplacoids. Accessory points and small lunules present. No other cuticular thickening present on the legs. Doryphoribius solidunguis sp. nov. has a very obvious reticular cuticular ornamentation with an irregular shape and size mesh (usually large) delimited by thick, sometimes protruding ridges that may form tubercles at crossings; cuticle of the legs smooth; peribuccal papulae present and two pairs of dorsal teeth lying along the anterior margins of the stylets sheaths. Pharyngeal bulb with apophyses and two macroplacoids. The claws are large and stout with very small accessory points; lunules present, those of the inner claws more evident than in similar species; a cuticular bar is present on the first three pairs of legs. Doryphoribius flavus was considered widespread, but this work exposing cryptic species indicates that the geographic distribution is more restricted.
