Two New Species

The mysid Surinamysis rionegrensis sp. nov. is described from Rio Negro, a large freshwater tributary of the Amazon. A supplemented description is given for the freshwater species S. robertsonae Bamber & Henderson, 1990, and its known distribution within the Amazon system is amended. A further representative of this genus, S. aestuaria sp. nov., is described from brackish waters within the estuary system of Rio Quatipuru on the NE coast of Brazil. These three species share large statoliths mineralized with vaterite, a metastable polymorph of crystalline calcium carbonate. Among the three flagella of the male antennula, the median, ventral one is identified as an accessory flagellum, as opposed to the Old World genera Mesopodopsis and Limnomysis, where the inner flagellum or lobe is accessory. The distinctive characters of Surinamysis and its five species are presented. The diagnosis of this genus is modified and a key to its species is given.

Abstract Supplemented descriptions are given for the genus Parvimysis Brattegard, 1969, and its freshwater species P. pisciscibus Henderson & Bamber, 1983, from the Amazon system upstream of the Rio Negro-Solimões confluence. Six new species are described from this range, based on differences regarding eyes, antennae, modified spines in the foregut, fourth male pleopod, and telson. A total of nine freshwater Mysidae species are now known from the Amazon Basin, revealing this system among world’s most species-rich in freshwater mysids. At least five species have the static bodies mineralized with vaterite, a metastable polymorph of crystalline calcium carbonate. The oostegites of at least six Parvimysis species show few setae but are exceptional in exhibiting discoidal structures for the attachment of eggs and larvae. A key to the Mysidae of Amazonia is provided, including keys to all currently known species of Parvimysis and Surinamysis Bowman, 1977.

Odontostilbe pulchra, previously considered species inquirenda in Cheirodontinae and doubtfully assigned from the río Orinoco basin, is redescribed with the rediscovery of two syntypes. Originally described to the Island of Trinidad, O. pulchra is widespread in Venezuela, the río Orinoco basin, in smaller coastal drainages of northern South America, in the Lake Valencia system, and río Essequibo basin. A punctual occurrence in the upper rio Negro, near southernmost headwaters of the río Orinoco, extends its distribution to the Amazon basin. Additionally, two new species of Odontostilbe from the río Orinoco basin are described.

Two New Species

Since the publication of the previous paper (Leeson, 1953), additional information has been accumulated on the geographical distribution of some of the Old World ticks of the genus Ornithodoros and two new species (zumpti and arenicolous) have been described. Much of this additional matter has been communicated to me by correspondents who have been kind enough to give permission for its publication here. Their names are enclosed in brackets after the new data to indicate the source and to these workers I tender my sincere thanks.

The subfamily Ticoplinae is Afrotropical, Oriental and Palaearctic in distribution with six species in two genera (Eosmicromyrmilla Lelej & Krombein, 2001 and Hindustanilla Lelej in Lelej & Krombein, 2001) known from the Oriental Region. Two new species, E. subbuka sp. nov., and E. balakrishnani sp. nov. were recently discovered in India (Western Ghats). Keys to the Old World genera of tribe Smicromyrmillini and species of Eosmicromyrmilla are provided. An updated diagnosis for males of Eosmicromyrmilla and photos of male genitalia for the genus are given. A new combination is proposed for E. margalla (Lelej & Ullah, 2007), comb. nov. The genus Eosmicromyrmilla is newly recorded from the fauna of Pakistan instead of the genus Smicromyrmilla Suárez, 1965, which is excluded from that fauna.

Two New Species

A tubiferous cirripede Tetraclitella judiciae sp. nov., previously known only from two isolated and incomplete shell wall plates identified as Tetraclitella sp. cf. T. purpurascens (Wood, 1815), is described from the early Miocene of Victoria, Australia; a further taxon, Tetraclitella purpurascens miocenica subsp. nov., occurs in the late Miocene-Pliocene of Victoria, and specimens from the early Miocene of New Zealand, previously recorded as Tetraclitella sp. cf. T. purpurascens (Wood, 1815) are redesignated as Tetraclitella nodicostata sp. nov. Tetraclitella is the first cirripede genus known to have had tubiferous walls. Incorporation of chitinous stringers within the shell wall of early tetraclitids (e.g. Epopella) may have facilitated the development of the tubiferous shell wall, which permitted sessile barnacles to maximise the shell strength to calcite ratio: in doing so, these chitinous stringers not only reduced the diversion of energy required to extract calcium carbonate from seawater, but improved the effectiveness of the shell wall in resisting predators. It is also argued here that the presence of chitin within the shell increased resistance to both corrasion and corrosion, the latter becoming an increasing problem for calcareous shelled organisms following a drop in the pH of seawater after the PalaeoceneEocene Thermal Maximum.

This paper presents a taxonomic revision of 28 described species of the genus Sirthenea Spinola, 1837 (Hemiptera: Heteroptera: Reduviidae: Peiratinae) distributed in the Afrotropical, Oriental, Palearctic, Oceanian and Australian zoogeographical regions. The following new synonymies are proposed: Sirthenea africana Distant, 1903 = S. rapax Horváth, 1909, syn. nov. = S. leonina Horváth, 1909, syn. nov. = S. bequaerti Schouteden, 1913, syn. nov. = S. leontovitchi Schouteden, 1931, syn. nov.; Sirthenea picescens Reuter, 1887 = S. atrocyanea Horváth, 1909, syn. nov.; S. rodhaini Schouteden, 1913 = S. collarti Schouteden, 1931, syn. nov. = S. angolana Villiers, 1958, syn. nov.; S. flavipes (Stål, 1855) = S. clavata Miller, 1948, syn. nov. = S. bharati Sucheta & Chopra, 1988, syn. nov. = S. koreana Kerzhner & Lee, 1996 syn. nov. = S. melanota Cai & Lu, 1990, syn. nov. = S. nigripes Murugan & Livingstone, 1990, syn. nov.; S. obscura (Stål, 1866) = S. glabra (Walker, 1873), syn. nov. A neotype is designated for S. picescens Reuter, 1887. Three species, S. erythromelas (Walker 1873), S. fulvipennis (Walker, 1873) and S. sobria (Walker, 1873), are excluded from the genus Sirthenea. Two new species from the Oriental Region, S. kali sp. nov. (India) and S. setosa sp. nov. (Malaysia) are described. Identification keys are provided for the subgenera and species from each zoogeographical region treated. Drawings of dorsal habitus and genitalic structures, drawings and images of selected morphological characters, and distribution maps of all valid species are presented.

Two New Species

Direct evidence bearing on identification of the two new species of Gangetic stingrays named Raia fluviatilis and R. sancur by Hamilton, 1822 comprises 1) the first written account by Hamilton (then Buchanan) of his encounters with Gangetic stingrays in 1807–1813, written at the time in manuscript, but not published until 1877; 2) Hamilton's accounts of Raia fluviatilis and Raia sancur published in 1822; 3) Hamilton drawing IV 7 in the archives of the Asiatic Society of Bengal (never published, original now lost); and 4) Hamilton drawing IV 65 in the same archives (published by Hora, 1929, original now lost; this drawing is not a copy or a version of drawing IV 7). The description of R. sancur clearly is based on a species of the genus Pastinachus. Drawing IV 7 presumably is the unfinished drawing of R. sancur mentioned by Hamilton, 1822, and is therefore also of a Pastinachus. Drawing IV 65, not mentioned by Hamilton, a complete drawing with dorsal and ventral views of a newborn male Pastinachus with an intact sting, is identified as based on Raia fluviatilis. Pending revision of the genus Pastinachus, the Gangetic species is tentatively identified as P. sephen (Forsskål, 1775). Identification of Raia fluviatilis with a large freshwater species of Gangetic Himantura advocated by Annandale, 1910; Chaudhuri, 1912; Compagno and Cook, 1996; and Zorzi, 1996 is based on unwarranted assumptions. There is no definite evidence that Hamilton ever saw a Gangetic Himantura. Himantura chaophraya Monkolprasit and Roberts, 1990 is the only available name applicable to huge large tropical Asian freshwater stingrays of the dasyatid genus Himantura. No specimens of Gangetic Himantura exist in present museum collections.
