Two New Species

Andeogryllus n. gen. including two new species from the inter-Andean slopes and valleys of the Magdalena and Cauca rivers of Colombia are described. This new genus is similar to Zebragryllus in their habitus, differed by not have white stripes on the body or antennae and by a modified pseudoepiphallic sclerite. The genus Atsigryllus (Atsigryllae group) is located in the subtribe Anurogryllina, highlighting the secondary reduction of the median lobe. An updated key is provided for the genera of the subtribe Anurogryllina and the species of the new genus.

Abstract The phylogenetic study of the deep-sea genus Bentheogennema is based on four molecular markers and 79 morphological characters. All four previously recognized species and two new species of Bentheogennema, representatives of all other genera and species groups of Benthesicymidae, and three outgroups were included in the analyses. We have examined and coded six major groups of morphological characters related to the carapace (three characters), the pleon and the telson (14), the mouthparts (nine), the armature of the pereopods (five), the thelycum (27) and the petasma (21). Results of morphological and molecular analyses were similar. Two species were transferred from Bentheogennema to other genera (for one of them a new genus was erected) and two new species of Bentheogennema were described. Three pelagic genera (Gennadas, Bentheogennema and a new genus) created a robust clade. The divergence of this clade is linked to ‘smoothening’ of the body (reduction of the branchiostegal spine on the carapace, reduction and loss of the dorsolateral spines and the end-piece on the telson) and elaboration of the copulatory structures. We provide amended diagnoses of these three pelagic genera and key to species of Bentheogennema.

AbstractThe new genus Deleyia gen. n., including two new species, D. poinari gen. n., sp. n. and D. aspiculata gen. n., sp. n., is described from terrestrial material (rotting wood and moss) in Ukraine. The new genus is inter alia characterised by the outer cuticular layer being defoliated along most of the body, except for labial region and tail posterior to phasmid, forming a cuticular sheath around the body and a vulval cuticular sac in females, and reduced stoma and basal bulb. Deleyia poinari gen. n., sp. n. is separated from D. aspiculata gen. n., sp. n. by a shorter body (L = 600-831 vs 756-945 μm), a shorter PUS (7-18 vs 44-69 μm), longer tail in both females and males (40-50 vs 32-38 μm and 37-48 vs 35 μm, respectively), and presence vs absence of spicules and gubernaculum. The phylogenetic position of Deleyia gen. n. and its relationships to the genera Daubaylia and Myolaimus are discussed.

Shape Pattern

Literature about Mesitiinae Kieffer, 1914 has not been treated extensively from a taxonomic viewpoint in comparison with other subfamilies in Bethylidae Latreille, 1802. Our research on species of Metrionotus Móczár, 1970, Clytrovorus Nagy, 1972 and Sulcomesitius Móczár, 1970 revealed a new hypopygium shape pattern, namely a ‘star-shaped’ hypopygium, which is characteristic of a new genus, Astromesitius gen. nov., with two new species Astromesitius thionyi gen. et sp. nov. and Astromesitius olavoi gen. et sp. nov. The descriptions of both new species are based on male specimens collected in Thailand and the United Arab Emirates. Astromesitius quatei (Móczár, 1977) gen. et comb. nov. is designated as type species for the new genus, which is erected for a total of seven species. The main diagnostic characteristics are the head longer than wide; a clypeus with a median lobe quadrate; an antenna with distinct long setae, with pedicel caliciform, and with flagellomeres long and caliciform; pronotum and anteromesoscutum with longitudinal sulcus indistinct or absent; metapectal-propodeal complex with posterior projection hardly distinct or absent; hypopygium star-shaped; genitalia with aedeagus slender and fusiform.

Two new species, including a new genus of rhigonematid nematode, are described from Archispirostreptus tumuliporus (Spirostreptida; Diplopoda) from Malawi. Brumptaemilius justini n.sp. resembles Brumptaemilius sclerophorus, the type species, and Brumptaemilius oschei in the form of the area rugosa in the male. It differs from male B. sclerophorus in having a caudal appendage which is longer and supports the last pair of caudal papillae; this pair is anterior to the caudal appendage in B. sclerophorus. Male B. justini differ from those of B. oschei in having a shorter caudal appendage, distinctly set off from the rest of the body, and in possessing a field of tiny bosses on either side in the anal region. Waerebekeia n.gen., with type species Waerebekeia simoni n.sp., resembles Brumptaemilius since males have a urceolate buccal cavity with three prominent pennate cuticular projections and three trifid teeth at its base. The genera are distinguished by the shape of the oral opening in the male (laterally elongate in Waerebekeia; subtriangular in Brumptaemilius), by the absence of an area rugosa and by the more dorsal position of the third papilla pair in male Waerebekeia.

Near Future

In the body-cavity of a Racket-tailed Drongo (Dissemurus paradiseus) which died at the Calcutta Zoological Gardens, and the blood of which was teeming with two species of microfilariae, were found males of two new species of filariae, together with a single female specimen. In a Hunting Cissa (Cissa chinensis), which died at about the same time, males of one of the species discovered in the Drongo were found again, accompanied by a single female different from that found before. Since this cissa also harboured two species of microfilariae in its blood, the identity of either of the females is doubtful. In another specimen of hunting cissa a single male specimen of an entirely different species, which I have made the type of a new genus, was found. Here again two species of microfilariae were discovered so that it is not possible to say which is the offspring of the adult found. It had been hoped that more infected specimens of these birds might be obtained so that the confusion as regards relationships of the females and offspring to the males might be cleared up, but there appears to be little hope of more being obtained in the near future.
