A taxonomic revision of the genus Lasianthus Jack. (Rubiaceae) from Thailand

A taxonomic revision of the genus Lasianthus Jack. from Thailand is made based on specimens in BKF, BK, L, AAU, K, BM, E, P, KEP, SING and PSU etc. Three species and three varieties are described as new; a new combination, L. trichophlebus subsp. barbellatus ( Ridley) H. Zhu, is made; eight species and five varieties are found to represent new records to Thailand; seven species, i.e. L. brevidens Craib, L. densifolius Miq., L. incomptus Craib, L. scalaris Craib, L. penicillatus Craib, L. virgatus Craib and L. zambalensis Elmer, axe reduced to synonyms; two species, L. brevipes Craib and L. lowianus King et Gamble are moved to the genus Saprosma; the delimitation of some species is clarified. As a result, fifty-two species, one sub-species and twelve varieties are recognized in the genus Lasianthus from Thailand.

A revision of the Mediterranean gobiid genus Chromogobius (Teleostei-Perciformes)

The Mediterranean gobiid genus Chromogobius (Teleostei-Perciformes) is redefined with additional information on lateral-line system and skeleton. The value of meristic features, colouration, squamation, and relative number of cephalic lateral-line papillae is shown for species and subspecies definition. Two species are recognized and described, the mediolittoral Ch. quadrivittatus (Steindachner, 1863) (type species) and the more offshore Ch. zebratus (Kolombatovic, 1891), with the latter being divided into the two subspecies Ch. z. zebratus (from Split, Adriatic Sea) and Ch. z. levanticus subsp. n . (Mediterranean coast of Israel; possibly Tyrrhenian Sea). Osteological confirmation for placing Chromogobius in the Gobiidae is provided, and Chromogobius shown to have affinity with certain South African species (Gobius nudiceps, G. caffer, G. natalensis, G. agulhensis, and Acentrogobius multi-fasciatus), as well as occupying an intermediate position between the Mediterranean Zebrus zebrus and Didogobius bentuvii.     

Phylogeny and species boundaries in the gobiid genus Gnatholepis (Teleostei: Perciformes)

Species of the goby genus Gnatholepis Bleeker, 1874, are common inhabitants of shallow tropical seas worldwide. In this study, mitochondrial DNA sequence (ND2 gene), from 349 Gnatholepis individuals sampled from across the South and Central Pacific and Caribbean, is used to infer phylogeny and determine species boundaries. Seven species of Gnatholepis are recognized: the Indo-Pacific G. anjerensis (Bleeker, 1851) [ G. cauerensis (Bleeker, 1853) is a synonym]; G. scapulostigma Herre, 1953; G. davaoensis Seale, 1910; G. knighti Jordan & Evermann, 1903; G. gymnocara Randall & Greenfield, 2001; G.  sp. Randall & Greenfield, 2001; and the Atlantic/Caribbean G. thompsoni Jordan, 1904. Results from the molecular phylogeny are compared with a previous morphology-based revision of the genus in order to establish which morphological characters diagnose species in correspondence with the molecular phylogeny.  © 2004 The Linnean Society of London, Zoological Journal of the Linnean Society , 2004, 142 , 573–582.

Cryptic diversity of the eel goby, genus Taenioides (Gobiidae: Amblyopinae), in Japan

The eel goby, genus Taenioides (Gobiidae: Amblyopinae), inhabits muddy bottoms of estuaries or shallow areas of seas in the Indo-Pacific Ocean. Among congeners, T. cirratus ( Blyth, 1860 ) has been thought to be distributed in Japan, but taxonomic confusions remain as to which scientific names are applicable to Japanese Taenioides species, or more fundamentally, how many Taenioides species are distributed in Japan, due in part to the rarity of this group in museum collections and the morphological similarity among species. To clarify the species diversity of the genus Taenioides in Japan, we conducted phylogenetic analysis on the basis of partial mitochondrial DNA sequences and morphological observation of more than 100 specimens. As a result, four distinct species were distinguished from each other, on the basis of both genetic divergences (2.9-5.7%, 16S rRNA gene) and morphological differences (i.e., degree of development of dermal folds on the head, numbers of barbels and vertebrae). Although the identifications of four species need additional verifications, they were identified as T. anguillaris, T. snyderi, T. gracilis and T. cf. kentalleni, and the species name T. cirratus does not seem to be appropriate to any of four detected species. Museum collections indicate that the two species, which are distributed in the main islands of Japan, were collected frequently and treated as a single species. The other two were each collected only from a single locality of Okinawa Island in this study, of which one seems to be uncommon worldwide as well.     

A new West Balkanian sand-goby (Teleostei: Gobiidae)

A new species of West Balkanian freshwater sand-goby Pomatoschistus montenegrensis sp. nov. (Teleostei: Gobiidae) is described from the Morača River, southern Montenegro, and shown to be related to the euryhaline Adriatic Pomatoschistus canestrinii . The generic status of these two species is discussed with reference to the limits of Pomatoschistus (type Gobius minutus ) and the status of a subgenus [ Ninnigobius (type-species Gobius canestrini )]. The habitat and the local distribution of the new species are described.

A redescription of the gobiid fish <Emphasis Type="Italic">Taenioides purpurascens</Emphasis> (Gobiidae: Amblyopinae) with comments on,and a key to,species in the genus

The Indo-West Pacific gobiid genus Taenioides Lacépède is further defined and one of the constituent species of the genus, T. purpurascens (De Vis 1884), is redescribed. Taenioides purpurascens is known only from the southeast coast of Australia and is compared to other species in the genus: T. anguillaris, distributed from India northeastward to China, and Japan, and southward to Australia; T. gracilis, distributed along the east coast of Africa and Madagascar to India, northeastward to Japan and southward to Australia; T. kentalleni, known only from Saudi Arabia and Japan; and T. snyderi, known only from southern Japan. Taenioides purpurascens is unique within the genus in having: the fewest dorsal-fin elements (41?44 vs. 48?72); the fewest anal-fin elements (34?38 vs. 41?65); the fewest vertebrae (27 vs. 28?45); and a 2-4-2 arrangement of the barbels on the ventral surface of the head (vs. 2-2-2, 2-3-2, or 2-4-2-2). In morphometric comparisons with these other species, T. purpurascens is shown to have the shortest and deepest body. A key to these species is provided.     

Asterropteryx atripes, a new gobiid fish from the Western Pacific Ocean (Perciformes: Gobioidei)

 A new gobiid fish, Asterropteryx atripes, is described on the basis of eight specimens from Iriomote-jima Island, Ryukyu Islands, and El Nido, Philippines. It differs from its congeners by having the following combination of characters: 3rd spine of first dorsal fin long, filamentous, distal tip usually over end of 2nd dorsal fin base when appressed in both sexes; pelvic fins almost separated, innermost (=5th) segmented rays connected by rudimentary low membrane between bases, and no frenum; 4–7 short spines on posterior margin of preopercle (the uppermost spine usually just behind the cephalic sensory canal pore N); eye large, 32.3–35.8% of head length; enlarged haemal arches on 1st two caudal vertebrae; a distinct black band from posterior margin of eye to caudal fin base (indistinct in dark-phase individuals); black pelvic fin (vivid in dark-phase individuals); numerous minute bright blue spots on head and body in life; no distinct dark spots on head and body; iris entirely reddish-brown or dusky (bright white ventrally in pale-phase individuals) when alive or fresh, and entirely black in preservation, without white transverse bar on middorsal surface; hovering habit. The new species appears to be most closely related with the other only known hovering species, A. striata; the latter is readily distinguished from the former in having no long, filamentous dorsal spine; semitranslucent pelvic fin; and a series of small black spots along dorsal fin base and dorsal edge of caudal peduncle. Asterropteryx contains two distinct groups, and the monophyly of the genus is open to question. Received: March 19, 2000 / Revised: February 25, 2002 / Accepted: April 25, 2002
