In this study, we describe two new Halamphora species (Halamphora subfontinalis and H. hezhangii) and identify three species newly recorded in China (H. elongata, H. submontana and H. tenella) and two others previously recorded from China (H. montana and H. dusenii), as well as make preliminary observations on three interesting and unnamed Halamphora species. For all ten taxa observations were made using light microscopy and for the new taxa scanning electron microscopical observations were also made. Comparisons of morphological features are made with similar, previously-described taxa. All of these Halamphora species were found in alkaline waters (7.2 < pH < 9.7) in the mountainous regions of southwest China, including Tibet, Yunnan and Guizhou Provinces. In addition, we list in Halamphora twenty taxa previously recorded from China in the genus Amphora, resulting in two new combinations.

The plant bug tribe Cylapini (Hemiptera: Heteroptera: Miridae: Cylapinae) is diagnosed and a worldwide key to the genera of the tribe is provided. The taxonomic review of the New World Cylapini genera Amapacylapus Carvalho & Fontes,1968 and Cylapus Say, 1832 is provided, including a key to species, diagnoses and redescriptions of genera and most included species, and descriptions of two new species, Amapacylapus unicolor sp. nov. (Ecuador) and Cylapus luridus sp. nov. (Brazil). Illustrations of the male genitalia, color photographs of the adult and scanning electron micrographs of the selected species are provided. The genus Cylapocerus Carvalho & Fontes, 1968 syn. nov. is proposed as a junior synonym of Cylapus with all species currently placed in Cylapocerus transferred to Cylapus. The following new combinations are established: Cylapus amazonicus (Carvalho, 1989) comb. nov., Cylapus antennatus (Carvalho & Fontes, 1968) comb. nov., and Cylapus tucuruiensis (Carvalho, 1989) comb. nov. Peltidocylapus labeculosus (Bergroth, 1922) is transferred to the genus Amapacylapus as Amapacylapus labeculosus (Bergroth, 1922) comb. nov. Male neotype is designated for Cylapus tenuicornis Say, 1832. The following new country records are provided: Amapacylapus amapariensis Carvalho & Fontes, 1968 (Ecuador, Guyana); Cylapus amazonicus (Bolivia, Ecuador); Cylapus antennatus (Ecuador); Cylapus citus Bergroth, 1922 (Bolivia, Brazil, Guyana, Peru); Cylapus marginicollis (Distant, 1883) (Nicaragua, Panama); Cylapus ruficeps Bergroth, 1922 (Brazil, Colombia, Ecuador); Cylapus tenuicornis (USA); Cylapus tucuruiensis (Venezuela).

Two new species of Gomphonema Ehrenberg are described based on light and scanning electron microscopical observations. These are Gomphonema kallarense sp. nov. found in India and G. kezlyae sp. nov. found in India and Vietnam. We also report and document the morphology and variability of G. doonense from Vietnam, a species previously described from India based on a limited number of valves. Both G. doonense and G. kallarense have striae composed of doubly-punctate striae that are without occlusions, while G. kezlyae has striae with single rows of areolae that have external occlusions giving the impression of C-shaped openings. Our investigation shows that India and Vietnam share some species in common, adding additional evidence that the biogeography of freshwater diatoms from the tropics warrants future investigation.

The genus  Herschelia (Disinae, Orchidaceae) is revised. Sixteen species, one subspecies and one variety are recognized. Two new species from tropical Africa (H. chimanimaniensis Linder and H. praecox Linder) and a new variety from the Cape Province H. lugens (H. Bol.) Kraenzl. var. nigrescens Linder are described. Three new combinations are made by transferring the two species of Forficaria and  Disa sect. Microperistera (one species) to Herschelia. Thirteen species are illustrated, and the nomenclature and the available information about the habitats of the taxa are discussed. The species are grouped into two subgenera, one of which is further divided into two sections and four series. This classification is based on the putative phylogeny, as determined by the method devised by Wagner (1962).

Two new diatom species from the Gomphonema subtile species complex were found in Đả Tiên reservoir, near the Town of Ðà Lạt, Lâm Đồng Province, Vietnam, as well as in the River Nam Leuk, Phou Khao Khouay, Laos. These new species include Gomphonema dalatica Glushchenko, Kulikovskiy & Kociolek sp. nov. and Gomphonema prowsei Glushchenko, Kulikovskiy & Kociolek sp. nov. Additionally, G. pantropicum Reichardt, a species known from the tropical zone, was found in our material. We provide light and scanning electron microscopical observations for all taxa, and offer formal descriptions for the two new species. Distribution of these three species is discussed.

Summary Two new species of philometrid nematodes (Philometridae), Barracudia notabilis n. sp. and Philometra consimilis n. sp., are described from males found in the ovary of the hound needlefish Tylosurus crocodilus (Péron et Lesueur) (Belonidae) from off the Atlantic coast of Florida, USA. Both species are described and illustrated based on light and scanning electron microscopical examinations. Barracudia notabilis n. sp., the first representative of this genus from fishes in the Atlantic Ocean, can be differentiated from other congeners by the body length of the male (2.69 mm), the length of the gubernaculum (57 μm) and spicules (81 μm), and by the shape of the gubernaculum. Philometra consimilis n. sp. differs from all congeners mainly in the unique structure of the distal tip of the gubernaculum (bearing two smooth dorsal barbs) and the species is also characterized by the length of spicules (111 μm) and the length of the gubernaculum (84 μm). Further studies are needed to discover and describe so far unknown gravid females of Barracudia spp.

Five species of the terrestrial diatom genus Luticola D.G.Mann were found during a taxonomic survey of two small volcanic islands, Ile Amsterdam and Ile Saint-Paul (Southern Indian Ocean). Apart from the two already known Luticola species L. beyensii Van de Vijver et al. and L. subcrozetensis Van de Vijver et al., two new species are described: L. ivetana Chattová & Van de Vijver sp. nov. and L. vancampiana Chattová & Van de Vijver sp. nov. Finally, one, up to now unknown, Luticola species is briefly discussed and illustrated. Detailed morphological descriptions of these taxa are provided based on both light and scanning electron microscopy observations. Morphological features of the new species are compared to morphologically similar taxa, and notes on their ecology and biogeography are added.

Two new species of Gomphonema Ehrenberg are described on the basis of light and scanning electron microscopical observations. These are Gomphonema kallarensis sp. prov., a species found in India, and G. kezlyae sp. prov., which have been found in India and Vietnam. We also document the morphology and variability of G. doonensis B. Karthick, R. Nautiyal et Kociolek from Vietnam. This species was described originally from India based on a limited number of valves. Both G. doonensis and G. kallarensis have biseriate striae composed of areolae without occlusions, while G. kezlyae have striae with single row of areolae that have external occlusions giving the impression of C-shaped openings. Our investigation shows that India and Vietnam share some species in common, and adding additional evidence that the biogeography of freshwater diatoms from the Tropics warrants future investigation.

Two new araphid diatom (Bacillariophyta) species, Pseudostaurosira oliveraiana sp. nov. and Staurosira catamarcensis sp. nov. are described from fossil material taken from the saline Laguna Colorada (Argentinian Altiplano). The morphology of the new species is studied using both light (LM) and scanning electron microscopy (SEM) and is compared to that of similar taxa. Pseudostaurosira oliveraiana sp. nov. is different from other species of Pseudostaurosira by its linear to lanceolate valve outline, with apices usually subcapitate and cuneate. Staurosira catamarcensis sp. nov. is unique because it has short striae that are restricted to the valve margins, delimiting a wide and lanceolate sternum, which resembles some species of Pseudostaurosira. Also, it is the first species described in Staurosira lacking apical pore fields, expanding the high morphological variation that already exists within this genus. Additionally, two new combinations are proposed: Pseudostaurosira santaremensis comb. nov. and Staurosirella canariensis comb. nov. based on information at the SEM and LM level presented in the literature.
