General Appearance

As part of a taxonomic revision of Rhodocodon, five new species are here described based on distinct syndromes of morphological characters and biogeographical patterns. Rhodocodon petrae resembles R. calcicola but differs in flower morphology and leaf size. Rhodocodon viridans is related to R. intermedius but differs in its proliferous bulb, synanthous leaves, green flowers and long style. Rhodocodon rubescens shows affinities to R. rotundus and R. campanulatus in general appearance but the former shows a different vegetative habit, thicker peduncle, shorter pedicels and larger flowers. Rhodocodon perrieri and R. siederi are related to R. mascarenensis but the two new species differ by the number and morphology of leaves, and flower morphology. A complete morphological description for all new species is provided, including data on biology, ecology and distribution. Furthermore, an identification key for all currently known Rhodocodon species is presented to facilitate future taxonomic work in this genus.

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.

N. brzeskii n. sp. is characterised by a body length of 774–922 µm, lateral fields with four incisures, delicate, short stylet (7–8 µm) with small rounded knobs, pyriform, offset or slightly overlapping basal pharyngeal bulb, posterior vulva position (V = 83.4–84.4), short PUS (5–10 µm), spicules 20.5–23 µm long, and thick tail with rounded to dull terminus. N. siddiqi n. sp. is characterised by a body length of 573–645 µm, six to nine incisures in lateral fields, delicate, short stylet (6.5–7.5 µm) with rounded knobs, pyriform or slightly elongate and offset basal pharyngeal bulb, V = 79.3–81.0, PUS = 26.5–40 µm, short spicules = 14.5–16.5 µm, and tail with rounded terminus. Morphometric data of the studied species are presented and intraspecific variation of their morphometrics and morphological characters is discussed. The list of world Nothotylenchus species is updated, and a dichotomous identification key and an updated tabular compendium for 41 valid species are provided.

As part of a taxonomic revision of the genus Massonia, a new species, M. obermeyerae is here described from South Africa. This species is at first sight similar to M. depressa, but it differs in the inflorescence and flower morphology, as well as its distribution. A complete morphological description of the new species and data on biology, habitat, and distribution are presented. Comments on typification of Massonia grandiflora, a name that has been misapplied to M. obermeyerae, are also presented, including the identification of a previously designated lectotype and a newly selected epitype.

AbstractThe monophyly of the family Lobalgidae comprising the genera Lobalges, Echimytricalges and Coendalges is tested using morphological characters and the maximum parsimony approach. Representatives of all subfamilies of the family Psoroptidae, the families Pyroglyphidae (Paralgopsis) and Psoroptoididae (Psoroptoides), and most families of the superfamily Sarcoptoidea were used as close outgroups, with Ptiloxenus (Ptiloxenidae) and Acarus (Acaridae) selected as distant outgroups. The analysis revealed polyphyly of the family: the two lobalgid genera Lobalges and Echimytricalges appear as sister groups, whereas the genus Coendalges is a member of a clade comprising genera of the psoroptid subfamily Psoralginae. The composition of the family Lobalgidae is here limited to these two genera, and the genus Coendalges is placed in the subfamily Psoralginae (Psoroptidae). A taxonomic revision of the family Lobalgidae is given, including descriptions of two new species, Echimytricalges lonchothrix sp.n. and E. proechimys sp.n. We also validate the species Echimytricalges whitakeri Fain and Ritzi, which had previously been a nomen nudum.

Syntypes of Peliosanthes bakeri and four varieties (var. clarkei, var. minor, var. princeps and var. violacea) of P. violacea were reexamined to review their identities. As a result, it turned out that the syntypes of P. bakeri comprise two species, P. griffithii and P. subspicata sp. nov., and those of P. violacea include at least six species, P. griffithii, P. khasiana sp. nov., P. macrostegia, P. subspicata, P. teta, and P. violacea. The two new species, P. khasiana from NE India and P. subspicata from Bangladesh and NE India are described and illustrated. The other four species recognised are taxonomically revised as to their identity, circumscription and distribution. In this connection, lectotypes for five taxa are designated. An identification key for the six species recognised is also provided.

An attractive and interesting new species, Muscari savranii Uysal & Doğu (Asparagaceae) is described and illustrated from central Anatolia, Turkey. A complete morphological description, detailed photographs, and a distribution map are reported for the new species, including an identification key for related species. Muscari savranii grows on the inclined limestone slopes in the province of Kayseri, Turkey. The closest species appears to be Muscari tenuiflorum Tausch, a member of the subgenus Leopoldia (Parl.) Rouy. In this study, diagnostic micro-macro morphological characters are discussed and compared with related taxa. Moreover, M. savranii is characterized in terms of its chromosomal features and a comparison with its relatives is given.

River Drainages

The taxonomic revision of the genus Lamontichthys Miranda-Ribeiro, based on the examination of 164 specimens of different river drainages throughout the Amazon basin, revealed the presence of six species of which two are new. Lamontichthys filamentosus occurs in the upper and middle portions of the rio Amazonas basin; L. llanero in the río Orinoco basin; L. maracaibero in the lago Maracaibo basin; and L. stibaros in the upper río Amazonas basin. Lamontichthys avacanoeiro, new species, occurs in the upper rio Tocantins basin; and L. parakana, new species, in the lower rio Tocantins basin. The new species represent a considerable extension in the so far known distribution of the genus. A parsimony analysis, including 87 osteological and external morphological characters from Lamontichthys and related taxa (total of 16), resulted in three most parsimonious trees with 194 steps (CI = 0.73 and RI = 0.78). The hypothesis of monophyly of Lamontichthys is corroborated and supported by six derived characters. Within Lamontichthys two monophyletic assemblages are recognized, one includes L. avacanoeiro and L. stibaros, the other includes L. maracaibero and the clade formed by L. filamentosus and L. llanero. The relationships of Lamontichthys parakana, a species that was not included in the phylogenetic analysis is discussed. The monophyly and relationships of the monotypic genus Pterosturisoma microps are also discussed.
