Fangfangia spinicleithralis, new genus, new species, is described from peat swamp forest habitats in Kalimantan Tengah, Borneo, Indonesia. It differs from all other cyprinids in having the anteroventral tip of the left cleithrum projecting into a strong anteriorly directed spine and a pointed posteriorly directed spine at the posteroventral aspect of each cleithrum. In addition, it can be diagnosed by the following characters: the base of the dorsal hemitrich of the first pectoral-fin ray with serrated margin, multicuspid pharyngeal teeth, ventrally directed lateral processes on vertebra 1, the high number of procurrent caudal-fin rays (14-18 dorsally, 11-15 ventrally), absence of scales with the exception of six or seven tubular lateral line ossicles, and the greatly elongated middle radials in the anal fin, which may reach half the length of proximal radials.
Fangfangia, new genus
Etymology. The new genus is named after the late Fang Fang, a passionate and productive cypriniform researcher, who left us too early, honouring her contribution to danionine taxonomy and phylogeny. Gender feminine.
Fangfangia spinicleithralis, new species
Distribution.Fangfangia spinicleithralis is presently known only from the type locality in Sebangau peat swamp forest, Kalimantan Tengah, Borneo, Indonesia.
Etymology. The species name spinicleithralis, an adjective, is derived from the Latin words spina, thorn, and cleithralis, belonging to the cleithrum(the main element of the dermal shoulder girdle). It refers to the unique pointed anterior and posterior spines on the cleithrum of this species.

Vanmanenia orcicampus, new species, is described from the Nam Ngum drainage on the Plain of Jars, central Laos. It is distinguished from its congeners by its colour pattern consisting of a midlateral row of six blotches, a middorsal row of six saddles and vermiculations between the rows of blotches and saddles and on the rest of the flank. Furthermore, it has a slender caudal peduncle (depth 1.5 times in its length, 2.5 times in body depth) and 12-14 branched pectoral-fin rays.

A new species of hypogean swamp eel, Monopterus rongsaw, is described from the Khasi Hills in Meghalaya, India. It was discovered while digging rock-strewn and moist soil close to a small stream during attempts to find caecilians. The new species differs from other synbranchids by the combination of absence of skin pigmentation, the eyes being tiny and covered by skin, and a count of 92 precaudal and 69 caudal vertebrae.

Hypostomus latirostris was originally described by Regan (1904) from “River Jungada [= rio Jangada], Matto Grosso and Goyaz”; however, the species is rarely mentioned in taxonomic works on Hypostomus from Paraguay. Herein, the two syntypes of Plecostomus latirostris were examined showing critical differences between them. After the analysis of a large sample of recently collected specimens from the upper rio Paraguay basin we concluded that the two syntypes from the rio Jangada indeed belong to different species. Hypostomus latirostris is redescribed and a lectotype is designated herein. The other syntype (now a paralectotype of H. latirostris) is designated as paratype of Hypostomus renestoi, new species. Hypostomus renestoi can be differentiated from H. latirostris by having robust teeth (vs. slender); by having 28-77 teeth on the premaxilla (vs. 79-111) and 25-64 on the dentary (vs. 79-109); by having small and more conspicuous dark spots (vs. larger and less conspicuous dark spots); by having dorsal and mid-dorsal series of plates with moderate hypertrophied odontodes (vs. lacking hypertrophied odontodes on lateral series of plates); and usually by attaining a smaller size.

Distribution and habitat.Hypostomus latirostris is known from several localities along the rio Cuiabá basin (Fig. 4). Regan (1904) pointed out the rio Jangada as the type locality. Records of H. latirostris were made in all the extension of the rio Manso and also in the rio Cuiabá basin. The rio Manso and the rio Cuiabazinho are the formers to rio Cuiabá. The rio Cuiabá basin is mainly located upstream the Brazilian Pantanal. Most specimens were collected before and after the construction of the Manso Reservoir. The rio Cuiabá basin has clear water, with rocky and sandy substrate, and variable remnant riparian vegetation. The individuals were collected whether in rapids or in lentic environments. Juveniles were usually collected in oxbow lakes in the rio Cuiabá basin and streams. Specimens of H. latirostris were collected co-occurring with H. boulengeri, H. cochliodon, H. khimaera, H. latifrons, H. piratatu, H. regani, H. ternetzi, H. peckoltoides, and H. mutucae.

Diagnosis. Hypostomus renestoi is distinguished from the species of the H. cochliodon group (sensu Zawadzki & Hollanda Carvalho, 2015) by having viliform teeth and angle between dentaries usually larger than 80° (vs. spoon- or shovel-shaped teeth and angle between dentaries about 80°); from H. affinis, H. ancistroides, H. arecuta, H. argus, H. aspilogaster, H. borellii, H. boulengeri, H. carinatus, H. careopinnatus, H. carvalhoi, H. commersoni, H. crassicauda, H. delimai, H. derbyi, H. dlouhyi, H. faveolus, H. formosae, H. hemiurus, H. interruptus, H. itacua, H. laplatae, H. niceforoi, H. nigrolineatus, H. nigropunctatus, H. paucimaculatus, H. piratatu, H. plecostomus, H. pantherinus, H. punctatus, H. pusarum, H. scabryceps, H. seminudus, H. subcarinatus, H. tapijara, H. variostictus, H. velhochico, and H. watwata by lacking keels on median lateral series of plates (vs. having moderate or strong keels along lateral series of plates); from H. alatus, H. albopunctatus, H. chrysostiktos, H. fluviatilis, H. francisci, H. margaritifer, H. luteomaculatus, H. lexi, H. luteus, H. margaritifer, H. meleagris, H. microstomus, H. multidens, H. myersi, H. niger, H. regani, H. roseopunctatus, H. scaphyceps, H. sertanejo, H. strigaticeps, H. tietensis, and H. variipictus by having dark spots on a clearer background (vs. pale spots or vermiculations on a darker background); from H. asperatus, H. brevicauda, H. goyazensis, H. heraldoi, H. hermanni, H. iheringii, H. kuarup, H. lima, H. luetkeni, H. macrops, H. mutucae, H. nigromaculatus, H. paulinus, H. topavae, H. unae, and H. wuchereri by having dorsal and mid-dorsal series of plates with moderate hypertrophied odontodes (vs. lacking conspicuous odontodes on lateral series of plates); from H. angipinnatus, H. agna, H. isbrueckeri, H. laplatae, H. latifrons, H. nigropunctatus, H. uruguayensis, and H. vaillanti by having one plate bordering supraoccipital (vs. three to seven); from H. bolivianus, H. fonchii, and H. perdido by having bicuspid teeth (vs. unicuspid teeth); from H. peckoltoides by having dark large spots on body and fins (vs. wide dark transverse bars on body and bands on fins); from H. ternetzi by having ventral unbranched caudal-fin ray length smaller to equal to predorsal length (vs. unbranched caudal-fin ray length clearly larger than predorsal length); from H. latirostris by having: robust teeth (vs. slender); by having 28-77 teeth on premaxilla (vs. 79-111) and 25-64 on dentary (vs. 79-109); small and more conspicuous dark spots (vs. larger and less conspicuous dark spots); dorsal and mid-dorsal series of plates with moderate hypertrophied odontodes (vs. lacking conspicuous odontodes on lateral series of plates); and usually by attaining a smaller size.
Ecological notes. Sometimes very small black dots due to encysted metacercariae on trunk, belly and fins (Figs. 5, 7).
Distribution and habitat. Hypostomus renestoi was mainly collected in the rio Cuiabá and its tributaries (Fig. 8). As a small- to medium-sized species, the specimens were collected in small- and medium-sized streams, with ranges from 1.5 to 6 m wide, as well as records were also from the margins or shallow stretches of the larger Cuiabá and Manso rivers. The area sampled presented varied vegetation of degraded areas by mining practices, recreation, pasture, agriculture, and often a small riparian vegetation. The streams usually had as substrate sand, clay, gravel and rocks. Several specimens were collected in rapids on mouth of the tributaries to the rio Manso. With the construction of Manso Reservoir the lower stretches of some tributaries of the rio Manso are nowadays flooded by the lake reservoir.
Etymology. The specific epithet renestoi is in honor of the professor Erasmo Renesto, Brazilian ichthyologist, due to his contributions to the genetic field of the Neotropical fishes.
