Four new Mouse Spider species (Araneae,Mygalomorphae, Actinopodidae,Missulena) from Western Australia

Four new species of the Mouse Spider genus Missulena Walckenaer, 1805 (family Actinopodidae) are described from Western Australia based on morphological features of adult males. Missulena leniae sp. n.(from the Carnarvon and Yalgoo biogeographic regions), Missulena mainae sp. n. (Carnarvon), Missulena melissae sp. n. (Pilbara) and Missulena pinguipes sp. n. (Mallee) represent a broad spectrum of morphological diversity found in this genus and differ from other congeners by details of the male copulatory bulb, colour patterns, eye sizes, leg morphology and leg spination. Two of the species, M. pinguipes sp. n. and M. mainae sp. n., are characterised by swollen metatarsi of the fourth legs in males, a feature not previously recorded in the family. A key to males of all named Missulena species from Australia is presented and allows their identification based on external morphology.     

Metallopolia, a new subgenus of Polia (Noctuidae,Noctuinae, Hadenini), with the description of two new species and a new subspecies

A new subgenus of Polia, Metallopolia subgen. n., two new species (Polia (Metallopolia) dysgnorima sp. n. and P. (M.) metagnorima sp. n.) from China (Sichuan, Yunnan, Gansu), and a new subspecies, P. (M.) subviolacea kanchenjunga ssp. n. from Nepal and SE Tibet (Sikkim) are described. Habitus, antennae, male and female genitalia of all Metallopolia species are characterised, depicted and compared with the related species.     

Two new species of Mediomastus (Annelida,Capitellidae) from Tokyo Bay,Japan

Two undescribed species of polychaetes in Mediomastus (Annelida: Capitellidae) were collected from intertidal to shallow habitats in Tokyo Bay, Japan. These are M. duobalteus sp. n. and M. hanedaensis sp. n. Mediomastus duobalteus sp. n. is distinguishable from all congeners by the following characters: 1) segments 3, 4, 8–11 stainable with methyl green, 2) thoracic capillary chaetae unilimbate, 3) abdominal capillary chaetae absent, 4) paddle-like chaetae in the thorax absent, and 5) abdominal hooded hooks not flared. Mediomastus hanedaensis sp. n. is similar to M. warrenae Green, 2002, but differs from the latter in the shapes of the thoracic capillary chaetae and the abdominal hooded hooks, and the staining pattern with methyl green. In addition, a key to all Mediomastus species is provided.     

Two new species of Myxobolus (Myxozoa: Myxobolidae) infecting the gill and scales of the smallmouth bass,Micropterus dolomieu (Centrarchiformes: Centrarchidae) in the French Broad River Basin,North Carolina

Two new species of Myxobolus Bütschli, 1882 (Bivalvulida: Myxobolidae) are described from the gill and scales of smallmouth bass (Micropterus dolomieu Lacepède, 1802 [Centrarchiformes: Centrarchidae]) from the Watauga River, French Broad River Basin, North Carolina, United States. Myxobolus intralamina n. sp. infects the lumen of the lamellar arterioles and Myxobolus infrabractea n. sp. infects the inner surface of the scale. They differ from all congeners by a combination of myxospore dimensions, polar tubule coil count, and the presence or absence of an iodinophilic vacuole in the sporoplasm and an intercapsular process. A phylogenetic analysis of the small subunit ribosomal DNA (SSU rDNA) recovered M. intralamina n. sp. sister to Myxobolus lepomis and Myxobolus branchiarum and M. infrabractea n. sp. sister to Myxobolus micropterii in a clade composed of five Myxobolus spp. infecting centrarchids and Henneguya spp. (Myxobolidae) infecting percids. Histological sections of infected gill revealed intra-lamellar plasmodia of M. intralamina n. sp. within the lumen of the lamellar arterioles and plasmodia of M. infrabractea n. sp. developing beneath the scales. These new species comprise the first species of Myxobolus reported from a black bass (Micropterus Lacepède, 1802) in the Southeast United States.     

New and little known species of the planthopper genus <Emphasis Type="Italic">Mycterodus</Emphasis> Spinola (Homoptera,Issidae) from the Eastern Mediterranean

Three new species of the genus Mycterodus Spinola are described: M. phoenicicus sp. n. from Lebanon and M. syriacus sp. n. from Syria, both belong to the subgenus Aegaeum Gnezdilov, and M. marki sp. n. from Turkey, belongs to the subgenus Aconosimus Dlabola. Figures of the described species and of the holotype of M. anaticeps Puton are given. M. efesicus Dlabola is for the first time recorded from Greece (Samos I.); M. alatus Logvinenko, M. caucasicus (Melichar), and M. johannesi Gnezdilov &; Drosopoulos are new to the fauna of Turkey.     

New species of Triplocania Roesler (Psocodea, ‘Psocoptera’, Ptiloneuridae), from Brazil and Ecuador

Four species of Triplocania, three with M3 simple, based on male specimens and one with forewing M3 forked, based on male and female specimens, are here described and illustrated, namely: Triplocania bravoi sp. n. (Napo: Ecuador), Triplocania erwini sp. n. (Napo: Ecuador), Triplocania trifida sp. n. (Mato Grosso and Rondônia: Brazil) and Triplocania lamasoides sp. n. (Rondônia: Brazil). They differ from all the other species in the genus, in which the males are known, by the hypandrium and phallosome structures. The female is first described for the M3 forked group. The identification key for males of the M3 forked group is updated.     

Taxonomical revision of “Arctonyx” fossil remains from the Liucheng Gigantopithecus Cave (South China) by means of morphotype and morphometrics,and a review of Late Pliocene and Early Pleistocene Meles fossil records in China

“Arctonyx” fossil remains from the Liucheng Gigantopithecus Cave, Guangxi, are redescribed and analysed in details. Detailed tooth character differences between Arctonyx and Meles are analysed. It is shown that materials from the Liucheng Gigantopithecus Cave actually belong to two species of Meles: Meles minor and Meles magnus n. sp. At the same time, a review of Late Pliocene and Early Pleistocene Meles records in China is made. During Late Pliocene, Meles are only represented by M. chiai and one archaic form. During Early Pleistocene, Meles from northern and central part of China are represented by two nearly sympatric species Meles chiai and Meles teihardi. Meles from South China are represented by M. minor and M. magnus n. sp., though the distribution of the two species is still unclear. M. magnus n. sp. is so far only known from the Liucheng Gigantopithecus Cave, whereas M. minor is probably also known from Longgupo, Chongqing in the central part of China besides Liucheng. Great diversity of Meles in Early Pleistocene in China indicates that the genus radiated earlier than previously thought. Phylogenetic analysis suggests M. magnus n. sp. is sister group to living M. leucurus, whereas M. minor and M. chiai are early branches in Meles evolution.     

Descriptions of Meloidogyne camelliae n.sp. and M. querciana n.sp (Nematoda:Meloidogynidae), with SEM and Host-Range Observations

Meloidogyne camelliae n.sp. on camellia (Camellia japonica) from Japan and M. querciana n.sp. on pin oak (Quercus palustris) from Virginia, USA, are described and illustrated. M. camelliae n.sp. is distingnishable from other species of the genus especially by its striking perineal pattern having heavy ropelike striae forming a squarish to rectangular outline with shoulders or projections, appearing sometimes ahnost starlike. M. querciana differs from other species by its characteristic perineal pattern round to oval in outline, sometimes with a low arch, and sunken vulva surrounded by a prominent obovate area devoid of striae. M. querciana shows some relationship to M. ovalis, but differs further fxom the latter by longer larvae, absence of annules on head of larvae, and rarity of males. Examination of specimens of M. camelliae n.sp. and M. querciana n.sp. with the scanning electron microscope confirmed observations made by optical microscopy and revealed diagnostic and other structures in greater detail. In greenhouse host tests, M. camelliae infected camellia heavily, showed moderate infection on oxalis, only a trace infection on tomato, and no infection on five other plants tested; and M. querciana attacked pin oak, red oak, and American chestnut heavily, but did not infect nine other test plants. In another test, pin oak seedlings did not become infected when heavily inoculated with and grown in the presence of two populations of M. incognita incognita and one of M. incognita acrita. The common names "camellia root-knot nematode" and "oak root-knot nematode" are respectively proposed for M. camelliae and M. querciana.     

Description of a New Species of the Genus Macromotettixoides Zheng (Orthoptera: Tetrigoidea: Metrodorinae) from China

A new species, Macromotettixoides lativertex Deng et al n. sp. is described with detailed illustrations of external morphology. Comparison between the species M. lativertex n. sp. and allied species is compiled into a table for identification. The distribution and an updated identification key to all known species of the genus is given.     

Meloidogyne grahami n. sp. (Meloidogynidae), A Root-knot Nematode on Resistant Tobacco in South Carolina

Meloidogyne grahami n. sp. is described and illustrated from specimens on tobacco (Nicotiana tabacum) originally from Florence, South Carolina. Considered for several years to be only a race of M. ineognita, this new species readily attacks NC-95 tobacco, a variety with resistance to the M. incognita group that is common in the major U.S. tobacco-producing areas. M. grahami n. sp. is related most closely to the three subspecies of the M. incognita group but differs from all of them, especially in its distinctive perineal pattern and larger larvae (av. 421 μm, vs. 385 μm or less). Also, the dorsal esophageal gland orifice of females of M. grahami n. sp. is further from the base of the styler (5 μm) than in M. i. incognita and M. i. acrita. Comments are given on the distribution of this new species.     

Morphological,Molecular, and Differential-Host Characterization of Meloidogyne floridensis n. sp. (Nematoda: Meloidogynidae), a Root-Knot Nematode Parasitizing Peach in Florida

A root-knot nematode, Meloidogyne floridensis n. sp., is described and illustrated from peach originally collected from Gainesville, Florida. This new species resembles M. incognita, M. christiei, M. graminicola, and M. hispanica, but with LM and SEM observations it differs from these species either by the body length, shape of head, tail and tail terminus of second-stage juveniles, body length and shape of spicules in males, and its distinctive female perineal pattern. This pattern has a high to narrowly rounded arch with coarsely broken and network-like striae in and around anal area, faint lateral lines interrupting transverse striae, a sunken vulva and anus, and large distinct phasmids. Molecular data from ribosomal IGS illustrate that M. floridensis n. sp. is different from the mitotic species M. arenaria, M. incognita, and M. javanica. Data from RAPDs confirm it and suggest that this new species lies in an intermediate phylogenetic position between the previous species and the meiotic species M. hapla, M. fallax, and M. chitwoodi. Differential host tests based on annual crops and on Prunus accessions are reported.
