    Would very much appreciate copies of the first two papers. The third is open access and results in a new genus for the orange chromide.

    Zootaxa 3835(3): An extraordinary new blind catfish, Xiurenbagrus dorsalis (Teleostei: Siluriformes: Amblycipitidae), from Guangxi, China

    Xiurenbagrus dorsalis, a new cave-dwelling amblycipitid catfish species, is described based on one specimen collected
    from the Pearl River drainage in Guangxi, China. The new species can be distinguished from congeners in having a unique
    combination of features, including the absence of eyes, long barbels, dorsal-fin origin posterior to vertical line at tip of
    pectoral fins and an adipose fin confluent with caudal fin. This is the first record of a blind catfish in China.

    Zootaxa 3841(2): Paraqianlabeo lineatus, a new genus and species of labeonine fishes (Teleostei: Cyprinidae) from South China

    Paraqianlabeo, new genus, is described from the Chishui-He and Wu-Jiang rivers of the Yangtze River basin in Guizhou
    Province, South China. This new genus is distinguished from all other labeonine genera by a combination of morphological
    and molecular evidence. It is distinguished from all other Asian garrains by a unique oromandibular morphology; i.e.,
    an arched, wide, rudimentary sucker formed by raised front and lateral margins of lower lip, postlabial groove and mental
    groove between middle and lateral lobes of lower lip chevron-shaped; anteroventral margin of rostral cap arched, thin and
    papillose; rostral cap not overlying upper lip, upper lip connected with lower lip around corners of mouth; well developed
    upper lip free from upper jaw; lower lip divided into two lateral fleshy lobes and one central plate, these two lateral fleshy
    lobes small and short, median lobe of lower lip large; anterior and anterolateral edges of upper and lower lip finely papillose;
    shallow, straight groove between lower lip and lower jaw; lower jaw bears thin, cornified cutting edge. Additionally,
    scales on mid-ventral region from pectoral fins to pelvic fins subcutaneous and half-hidden; dorsal fin with 3 simple and
    7½-8 branched rays. Paraqianlabeo lineatus, new species, type species of this genus, has longitudinal dark stripe along
    side of body. Analyses of mitochondrial DNA data indicate that this new genus forms a highly diverged lineage within the
    Garraina group of Labeoninae.

    Zootaxa 3838(5): Validation of the South Asian cichlid genus Pseudetroplus Bleeker (Pisces: Cichlidae).

    The South Asian Cichlidae are composed of two clades that together represent the sister group of the Madagascan genus
    Paretroplus Bleeker. Chaetodon suratensis Bloch and Etroplus canarensis Day are retained in Etroplus Cuvier, while
    Chaetodon maculatus Bloch is allocated to Pseudetroplus Bleeker. Pseudetroplus is distinguished from Etroplus in
    having, among other characters, 11 (vs. 12–13) pleural ribs; 26–27 (vs. 28–29) vertebrae; the anterior half of the median
    suture between the lower pharyngeal jaw serrated (vs. smooth); the first 6 anal-fin pterygiophores arranged anterior to
    the first 3 (vs. 2) haemal spines; the supraoccipital-exoccipital prong extending ventrally about half-way across the
    foramen magnum (vs. not extending into the foramen magnum); and the anterior jaw teeth tricuspid, acuminate (vs.
    unicuspid, spatulate). Microgaster Swainson is a synonym of Pseudetroplus and a junior homonym of Microgaster
    Latreille in Hymenoptera.
