Abstract Two new species of Aphanonchus are described from Germany and Ivory Coast. Aphanonchus europaeus sp. n., from Germany, is best characterised by 1.1-1.4 mm long body, presence of 50-96 lateral epidermal glands; female without neck setae, with straight vagina without sclerotisations and three to nine prevulval alveoli; male with a pair of neck setae, 15 tubular and 20 alveolar supplements, one pair of precloacal and four pairs of caudal setae, 39 μm long spicules. Aphanonchus africanus sp. n., from Ivory Coast, is characterised by 1.0-1.3 mm long body, presence of 37 to 71 lateral epidermal glands; female with a pair of neck setae, straight to slightly sinuous vagina without sclerotisations, and without alveoli; male with a pair of neck setae, 12-18 tubular and 54-80 alveolar supplements, a pair of precloacal and four pairs of caudal setae, 35.5-43 μm long spicules. Morphological data, based on specimens of A. bayensis from Costa Rica, A. multipapillatus from Colombia and Suriname, A. obesus from Ivory Coast and the type locality in Vietnam, and type specimens of A. longiceras, are presented and supplement the descriptions of these four species. An emended diagnosis and a revised classification of Aphanonchus are proposed and a key to the species of the genus is provided.

Two New Species

The Neotropical genus Himantigera James in James & McFadden, 1982, is revised. Two new species are described and illustrated—H. amauroptera nov. sp. (Costa Rica, Panama, Colombia), and H. xanthopoda nov. sp. (Mexico, Nicaragua, Costa Rica). Three species are transferred from Himantigera to Sargus Fabricius, 1798—S. dichrous (Schiner, 1868) comb. nov., S. flavoniger Lindner, 1928 comb. rev. and S. fulvithorax (Bigot, 1879) comb. nov. One species is transferred to Microchrysa Loew, 1855—M. splendens (Schiner, 1868) comb. nov. Himantigera jamesi Lindner, 1969 syn. nov. is proposed as a junior synonym of H. superba Lindner, 1949. The type species H. silvestris McFadden, 1982, as well as H. nigrifemorata Macquart, 1847 and H. superba Lindner, are herein redescribed and illustrated. Photographs of the type specimens of these three species are provided. Two unnamed species of Himantigera (sp. A and sp. B) are also described given that they have slight differences, but because we had only one specimen of each species, we did not officially describe them. This updates the total number of extant Himantigera from eight sensu Woodley (2001) to seven species. The species Merosargus apicalis Lindner, 1935, although never referred to the genus Himantigera or Himantoloba McFadden 1970, is also transferred to the genus Sargus. A key to all species of Himantigera and a map expanding geographical distribution of the genus are also presented, with the first records of the genus for Nicaragua, Colombia, Venezuela, Trinidad and Tobago, Ecuador and Bolivia.

AbstractA new species, Platydipteron balli (type locality near San José, Costa Rica), and first male specimens of Platydipteron are described. Based on these specimens, the genus is transferred from the Aenigmatiinae to the Metopininae. Male terminalia of Postoptica platypezoidea are described, and the genus is placed in the subfamily Phorinae.

AbstractThe genus Anonchus is revised. The genera Assia and Haconnus are considered to be synonymous with Anonchus on the basis of the morphological analysis. Additional descriptions of six species, viz. A. maculatus , A. mirabilis , A. millelacunatus , A. palaeotropicus , A. coomansi and A. pulcher are provided on the basis of type material or recently collected populations. The lectotype of A. monohystera is designated and described and the synonymy of this species with A. maculatus is confirmed. Two new species are described; A. winiszewskae sp. n. from Paraguay and A. venezolanus sp. n. from Venezuela. Several aspects of the morphology are described and the variability and diagnostic significance of the main morphological characters discussed. A study of intrageneric and suprageneric taxonomy of the genus Anonchus is presented. The subfamily Aphanolaiminae is reinstated for the genera Aphanolaimus, Aphanonchus and Paraphanolaimus and raised to family rank. The family Aphanolaimidae includes two subfamilies: Aphanolaiminae and Anonchinae. An emended diagnosis and a revised classification of Anonchus are proposed and a key to the species of the genus is provided.

Taxonomical and morphological notes on the species in the “cruciata-group” of Rhiginia Stål, 1859 (Heteroptera, Reduviidae, Ectrichodiinae, Ectrichodiini) are provided. Photographs of the type specimens of R. bimaculata Breddin, 1914, R. cinctiventris (Stål, 1872), R. crucifera (Stål, 1872), and R. crudelis Stål, 1862 are presented. Rhiginia lourdesae sp. nov. and Rhiginia nicholsae sp. nov. are described based on male specimens from Mexico and considered as members of the “cruciata-group”. We also provide an updated key to the New World genera of Ectrichodiinae that includes the genus Tribelocodia Weirauch, 2010 to reflect recent taxonomic changes to the classification of the subfamily.

Abstract Two known and one new species of Paraphanolaimus are described, viz. P. behningi from Germany, P. anisitsi from Paraguay and Germany and P. paraguayensis sp. n. from Paraguay. Paraphanolaimus paraguayensis sp. n. is characterised by 0.84-0.94 mm long body, presence of 37-44 lateral epidermal glands, strongly sclerotised and broad cylindrical stoma, swollen tail tip; female reproductive system with developed spermathecae, straight vagina; male without neck setae, 16-19 tubular supplements, two precloacal and nine to ten caudal setae, spicules 32-33 μm long, arcuate, with oval manubrium and fusiform shaft, platelike gubernaculum. Paraphanolaimus indicus and P.micoletzkyi are considered as species inquirendae. An emended diagnosis and a revised classification of Paraphanolaimus are proposed and a key to the species of the genus is provided. Aphanonchus bayensis (Keppner, 1988) comb. n. is proposed for Paraphanolaimus bayensis Keppner, 1988.

First Time

Many studies have focused on the taxonomy and phylogeny of the family Galaxauraceae with the use of molecular markers, allied to morphological taxonomy, providing a better understanding of the phylogenetic relationships within the family, as well assisting with the specific delimitation. For the Brazilian coast, Galaxauraceae has few studies with morphological taxonomy, but lack studies with a molecular focus. The diversity of Galaxauraceae was assessed in northeastern Brazil (Bahia state) using rbcL and COI-5P, as well as morpho-anatomical analyses. We report four species from Brazil: Dichotomaria huismanii (the first report for the Brazilian coast), D. obtusata, Galaxaura rugosa, and Tricleocarpa fragilis. Molecular and morphological data supported the establishment of two new species for Galaxauraceae: Tricleocarpa laxa sp. nov. and Dichotomaria viridis sp. nov. Tricleocarpa laxa formed a well-supported clade sister to T. natalensis (South Africa, type locality) and T. cylindrica (Australia) in both rbcL and COI-5P analyses, whereas Dichotomaria viridis, formed a moderate clade sister to D. huismanii. The Brazilian sequences of D. huismanii grouped with sequences from the type locality (Bermuda) showing no intraspecific divergence for rbcL, and very low divergence values for COI-5P. The record of D. huismanii in Brazil expands its geographical distribution to the South Atlantic Ocean. Male plants are described for the first time for this species. Even though our results are restricted to a region of northeastern Brazil (Bahia), they clearly revealed a hidden diversity of Galaxauraceae in Brazil.
