The species of Charaxwere reviewed by Lucena (1987) who a little later (1989) added three new species to the genus. Examination of recently collected specimens from museum collections documented the more extensive geographic distribution for most species and revealed the existence of a new species in which superficial neuromasts were discovered and are herein described. These skin structures were also detected in C. metae Eigenmann, 1922. Anal- and pelvic-fin hooks previously observed only on the anal-fin of one species of the genus are described herein in some other species. Charax unimaculatus Lucena is considered a junior synonym of C. michaeli Lucena. All the species are redescribed and the new species described.

A new shallow-bodied species of Moenkhausia is described from the upper Rio Negro, Amazon basin, Brazil. The new species is diagnosed from all congeners by the combination of a body depth not surpassing 33% in SL in adult specimens, seven scale rows between dorsal-fin origin and lateral line, five scale rows between pelvic-fin insertion and lateral line, a single conspicuous vertically elongated humeral blotch, and a conspicuous caudal peduncle blotch extending to the distal margin of the median caudal-fin rays. The new species was collected together with Jupiaba zonata, with which it shares a very similar color pattern. The similarity between these two taxa is interpreted as an additional case of Batesian mimicry between Moenkhausia and Jupiaba.

A New Species

A new species of Cyphocharax, Curimatidae, apparently endemic to the blackwater upper rio Negro of the Amazon basin in northern Brazil, is described.The new species is readily distinguished from its congeners by the presence of a distinctly longitudinally elongate, posteriorly vertically expanding patch of dark pigmentation along the midlateral surface of the caudal peduncle, with the patch extending from the base of the middle caudal-fin rays anteriorly past the vertical through the posterior terminus of the adipose fin. The new species additionally differs from all congeners in details of body and fin pigmentation and meristic and morphometric ratios. Evidence for the assignment of the species to Cyphocharax and the occurrence of other species of the Curimatidae apparently endemic to the upper rio Negro catchment is discussed.

The harvestman genus Bonea Roewer, 1914 and its type species B. sarasinorum Roewer, 1914 are redescribed based on the type material. In addition, two new species of Bonea from Hainan Island, China, are described and illustrated: B. zhui sp. nov. and B. tridigitata sp. nov. A new species of Lomanius Roewer, 1923 from Yunnan Province, China, is also described and illustrated: L. bulbosus sp. nov.. Keys to the 10 species of Bonea and the six species of Lomanius are provided. Paralomanius Goodnight & Goodnight, 1948 is revalidated from the synonymy of Lomanius, carrying as junior synonym Eulomanius Roewer, 1949, and containing two species from Micronesia (Paralomanius longipalpus Goodnight & Goodnight, 1948) and Philippines (Paralomanius mindanaoensis (Suzuki, 1977) new status). Bonea is transferred from the Ibaloniinae to Podoctinae. These are the first records of named species of Podoctidae from China.

Priocharax nanus, new species, is described from the rio Negro, Brazil. It is a miniature fish that retains as an adult the larval rayless pectoral fin, a diagnostic character of the genus. Priocharax nanus possesses fewer reductive features compared to congeners, P. ariel and P. pygmaeus, from which it can be distinguished by the presence of i,6 pelvic-fin rays (vs. i,5), the presence of the claustrum (vs. claustrum absent) and the presence of two postcleithra (vs. postcleithra absent). An updated list of 213 species of miniature Neotropical freshwater fishes is presented. The greatest diversity among them is represented by the Characiformes with 87 miniature species.

A New Species

The taxonomy of several genera of the tribe Dicerurini (subfamily Porricondylinae) is revisited, induced by the discovery of 11 new species in Malaise catches of various provenances. The bulk of the specimens interpreted here is of Swedish origin. Species described as new to science are Desertepidosis grytsjoenensis sp. nov. (from Sweden), D. robusta sp. nov. (Sweden), Linnaeomyia pratensis sp. nov. (Czech Republic), Neurepidosis ekdalensis sp. nov. (Sweden), N. emarginata sp. nov. (Sweden, Czech Republic), N. hybrida sp. nov. (Sweden), Tetraneuromyia brevipalpis sp. nov. (Sweden, Slovak Republic), T. discrepans sp. nov. (Sweden), T. errata sp. nov. (Sweden), and T. lapponica sp. nov. (Sweden). A new genus, Gardenforsia gen. nov., is introduced for G. oelandica sp. nov. (Sweden), a new species with regressive male morphology. The generic definitions of Desertepidosis Mamaev & Soyunov, 1989 (including Ubinomyia Mamaev, 1990 syn. nov. as new junior synonym) and Linnaeomyia Jaschhof & Jaschhof, 2015 are revised. A key to males of Desertepidosis is presented. New information on the morphology and geographic distribution is provided for Linnaeomyia hortensis Jaschhof & Jaschhof, 2015; Tetraneuromyia bulbifera Mamaev, 1964; and T. lamellata Spungis, 1987.

The fauna of the bryocorine plant bug tribe Dicyphini in eastern Asia (including Japan, Korea, Russian Far East and Taiwan) is reviewed, with emphasis on the genus Nesidiocoris Kirkaldy, which is rediagnosed and discussed. Twelve species in six genera are now recognized. Three new species of Nesidiocoris are described from Japan: Nesidiocoris nozakianus sp. n., N. okinawanus sp. n. and N. simotukensis sp. n. Nesidiocoris poppiusi (Carvalho) is proposed as a junior synonym of N. tenuis, and N. plebejus (Poppius) is transferred to Singhalesia China & Carvalho. An annotated checklist and a key to genera and species are also provided to aid in appreciating the east Asian dicyphine fauna.

ABSTRACT A new species of Boehlkea is described from rio Japurá, Amazon basin. The new species differs from B. fredcochui by the presence of a vertically elongate humeral spot (vs. absence), complete lateral line (vs. incomplete), four rows of scales below lateral line (vs. three), and lower number of branched anal-fin rays (17-21 vs. 22-25), and from B. orcesi by the higher number of maxillary teeth (13-14 vs. 5-12), greater head length (27.9-29.9% vs. 24.3-27.5% of SL), and by the color pattern (basal half of dorsal-fin, distal portion of pelvic-fin, lower caudal-fin lobe and anal-fin with black chromatophores vs. absence of black chromatophores in the fins).

Taxonomic Review

The genus Phasmotaenia Navás, 1907 (type-species: Taeniosoma sanchezi Bolívar, 1897) is currently known only from the Philippine Islands and Taiwan, but here shown to extend eastwards as far as to the Solomon Islands, Northern New Guinea and even Fiji. A taxonomic review of the genus, and updated keys to the species are presented. The type-species of Phasmotaenia Navás, 1907, P. sanchezi (Bolívar, 1897) from Luzon, Philippines is shown to have been misinterpreted by previous authors. This has resulted in the description of the here revealed junior synonym Phasmotaenia elongata Zompro & Eusebio, 2000 (n. syn.). A survey of the intraspecific variation of P. sanchezi (Bolívar, 1897) is provided along with illustrations of the holotype. Phasmotaenia australe (Günther, 1933) from the Solomon Islands is removed from synonymy with Phasmotaenia godeffroyi (Redtenbacher, 1908) n. comb. from Micronesia and shown to be a distinct and valid species (rev. stat.). Both species are transferred to Phasmotaenia Navás, 1907. Examination of the paratypes of P. australe (Günther, 1933) has revealed these to represent two different species distinct from the holotype, one of which is described as new herein (P. guentheri n. sp.). The male of P. australe is

A New Species

A new species of Hemigrammus is described from the upper Rio Negro, Amazon basin, Brazil. The new species is distinguished from all congeners by its unique color pattern consisting of a single humeral blotch clearly spaced from a conspicuous midlateral dark stripe, which extends from fifth or sixth anteriormost vertical scale row to the basis of the middle caudal-fin rays. Comments on its putative relationships are provided.
