Phlebotomus (Legeromyia) multihamatus subg. nov., sp. nov. from Gabon (Diptera: Psychodidae)

During a research project aimed at the study of the Culicinae fauna of Gabon and carried out in the National Park of La Lopé, we captured an unknown sandfly male specimen (genus Phlebotomus) by CDC miniature light trap belonging to a new species for Science. Furthermore, the originality of his genitalia does not allow us to include this species in one of the existing subgenus, thus in this paper we propose the creation of a new subgenus, as Phlebotomus (Legeromyia) multihamatus sp. nov., subg. nov. described from the National Park of La Lopé, through one male captured with CDC miniature light trap. A new species and a new subgenus of sandfly is characterised by a short style with three spines, a paramere wearing a basal hook as well as a basal pouch and the absence of basal lobe on the coxite. The originality of the genitalia of the male gives way to discussion about potential primary homologies between P. multihamatus sp. nov. and Phlebotomus (Abonnencius) fortunatarum, Phlebotomus (Anaphlebotomus) stantoni and Phlebotomus (Euphlebotomus) argentipes, which should be verified for future studies. The discovery of this new species in Gabon must encourage the study of sandflies in this country.     

Trichodorus elefjohnsoni n. sp. (Nemata: Trichodoridae) from Undisturbed Appalachian Forest

A new species of Trichodoridae, Trichodorus elefjohnsoni, is described from undisturbed regions of Great Smoky Mountains National Park, United States. It resembles T. orientalis De Waele &Hashim, 1984, T. persicus De Waele &Sturhan, 1987, and T. taylori De Waele, Mancini, Roca, '' Lamberti, 1982 in arrangement of ventromedian cervical papillae and posterior preanal supplements, but differs by combinations of the following characteristics: body length 516-731 μm; spicule length 33-50 μm, spicules densely striated, constricted medially; vaginal sclerotizations ovate; one pair of lateral body pores near vulva.     

Taxonomic revision of the genus Callimerus Gorham s. l. (Coleoptera,Cleridae). Part I. latifrons species-group

The latifrons species-group (=Brachycallimerus sensu Chapin 1924, Corporaal 1950; = flavofasciatus-group sensu Kolibáč 1998) of Callimerus Gorham is redefined and revised. Five species are recognized including one new species Callimerus cacuminis Yang & Yang sp. n. (type locality: Yunnan, China). Callimerus flavofasciatus Schenkling, 1902 is newly synonymized with Callimerus latifrons Gorham, 1876. Callimerus trifasciatus Schenkling, 1899a is transferred to the genus Corynommadius Schenkling, 1899a. Callimerus gorhami Corporaal, 1949 and Callimerus pallidus Gorham, 1892 are excluded from the latifrons species-group (their assignment to a species-group will be dealt with in a subsequent paper). A key to species of the latifrons species-group is given and habitus of each type specimen, male terminalia, and other diagnostic characters are illustrated.     

Three New Species of the Super Family Neotylenchoidea (Nematoda: Tylenchida) from Pakistan

Three new species in the super family Neotylenchoidea collected in Pakistan during 1979-80 are described. New species Nothotylenchus gohleni is related to N. affinis Thorne, 1941 but is differentiated by its longer, more robust body with tine cuticular annules, a more posterior vulva, inconspicuous basal knobs of the stylet, and poorly developed metacorpal area. N. geraerti and N. tuberosus are also close to this undescribed species, hut they have a more developed metacorpal area and a larger post uterine sac. Boleodorus zaini n.sp. is distinguished by its excretory pore open at a level with the base of the posterior esophageal bulb and by six distinct lines in the lateral field. Paurodontella sohailai n.sp. is closely related to P. densa (Thorne, 1941) Hussain &Khan, 1967 and P. minuta Hussain &Khan, 1967 but differs from them by its larger body, shape of tail, and seven incisures in the lateral field.     

A revision of the New World species of Gymnoclasiopa Hendel (Diptera,Ephydridae)

Species of the shore-fly genus Gymnoclasiopa Hendel from the New World are revised, including Gymnoclasiopa grecorum sp. n. (Alaska. Juneau: Gastineau Channel, Thane Road (S Juneau; 58°16.9''N, 134°22.4''W)) and Gymnoclasiopa matanuska sp. n. (Alaska. Matanuska-Susitna: Palmer (Matanuska River; 61°36.5''N, 149°04.1''W)). We also clarify the status of previously described species, including those now discovered to have Holarctic distributions and/or for which sexual dimorphism was not appreciated and the species was described twice, including Gymnoclasiopa montana (Cresson) as a syn. n. of Gymnoclasiopa bohemanni (Becker). Two species, Gymnoclasiopa bella (Mathis), comb. n., and Gymnoclasiopa chiapas (Mathis), comb. n., are transferred from Ditrichophora to Gymnoclasiopa, and Gymnoclasiopa cana Cresson stat. rev. and Ditrichophora canifrons Cresson, stat. rev. are returned to Ditrichophora, the genus in which Cresson originally described them. A neotype is designated for Gymnoclasiopa tacoma to stabilize the nomenclature of this species. The two excluded species, Ditrichophora cana and Ditrichophora canifrons, are diagnosed and distributional data are also provided. For all known New World species of Gymnoclasiopa, structures of the male terminalia are described for the first time and are fully illustrated. Detailed locality data and distribution maps are also included. To provide context and also to facilitate identification, diagnoses are included for the tribe Discocerinini and genus in addition to a key to the genera and species occurring in the New World.     

Hymenopteran parasitoids of the ant-eating spider Zodarion styliferum (Simon) (Araneae,Zodariidae)

Calymmochilus dispar Bouček & Andriescu (Hymenoptera, Eupelmidae) and Gelis apterus (Pontoppidan) (Hymenoptera, Ichneumonidae) are newly recorded as parasitoids of the ant-eating spider Zodarion styliferum (Simon) (Araneae, Zodariidae). The larvae of both parasitoid species fed on juvenile spiders. The final instar larva and pupa of Calymmochilus dispar and the male of Gelis apterus are described for the first time. Both species represent new distribution records for Portugal. The biology and host associations of the parasitoids are discussed.     

A new species of Haplothrips from southern Iran (Thysanoptera,Phlaeothripidae)

Haplothrips herajius sp. n. is described from leaves and flowers of a species of Suaeda in the south of Fars Province, Iran. This is the second Iranian species of Haplothrips with the unusual character state of extra setae on the metanotum. Information on variation in color and structure of the new species is provided. The similarities and host plant associations of this new species and Haplothrips kermanensis are discussed,as both are phytophagous on species of Chenopodiaceae.     

Description of Trilineellus clathrocutis n.g., n.sp. (Tylenchorhynchinae: Tylenchida Thorne, 1949) with a Key to Species and Observations on Tylenchorhynchus sensu stricto

TrilineeIlus clathrocutis n.g., n.sp. is described and illustrated. It was found as an associate of corn (Zea mays) in Stockton, Georgia, USA, and is related to a group of Tylenchorhynchus sensu lato species having three lines in nonareolated lateral fields. This new species is closely related to Tylenehorhynehus divittatus Siddiqi 1961, T. sculptus Seinhorst 1963, and T. triglyphus Seinhorst 1963 (syn. T. chonai Sethi & Swarup 1968) Tarjan 1973. It differs from these species primarily by having longitudinal striae on the body. These four species are differentiated from Tylenchorhynchus sensu stricto by having three lateral lines instead of four. They differ from Uliginotylenchus Siddiqi 1971 by having nonareolated lateral fields, fewer than 25 annules on conoid rounded tails, differently shaped gubernacula, nonattenuated stylets, and other distinctive characters. They differ from Triversus Sher 1973 by having the male tail enclosed by the bursa and by having rounded female tails. SEM observations of T. clathrocutis reveal a cuticle deeply cut by longitudinal and horizontal striae and bearing wide (> 2.0 μm) annules. Trilineellus is proposed to accommodate the new species and the three-incisured species still within Tylenchorhynchus. Tylenchorhynchus is thereby the repository for species within Tylenchorhynchinae having four lines in the lateral field, no conspicuous labial disc, and bursa enclosing the male tail.     

Neosteinernema longicurvicauda n. gen., n. sp. (Rhabditida: Steinernematidae), a Parasite of the Termite Reticuldermes flavipes (Koller)

A nematode isolated from the termite Reticulitermes flavipes (Koller) was identified and described as a new genus and species, Neosteinernema longicurvicauda. Primary distinguishing characters, by contrast to members of the genus Steinernema, were females having prominent phasmids, a curved tail longer than the body width at the anus, a spiral shape in juvenile-bearing females, and juveniles becoming infective-stage juveniles before emerging from the female; males having prominent phasmids, a digitate tail tip, a characteristic shape of the spicules (foot-shaped with a hump on the dorsal side), and 13-14 pairs of genital papillae, with eight pairs preanal; and infective juveniles having prominent phasmids and a filiform curved tail as long as the esophagus. Adult nematodes are found outside the termite cadaver. Diagnosis of the family Steinernematidae was emended to accommodate the new species.     

Description and Bionomics of Mesomermis camdenensis n. sp. (Mermithidae), a Parasite of Black Flies (Simuliidae)

Mesomermis camdenensis n. sp. is described from larvae of Simulium tuberosum (lundstroem) collected in Camden Valley Creek, Washington County, New York. This species possesses a barrel-shaped vagina, vulval flap. two short separate spicules, terminal mouth, six longitudinal chords, six cephalic papillae, large sexually dimorpbic anaphids, an esophagns of uniform width which extends for less than one-third of the body length, and a cone-shaped tail directed ventrally without appendage. Juveniles also are described and illustrated.A detailed morphological comparison with the mermithid M. flumenalis Welch is presented. The most pronounced morphological differences between these species are in the shape of the vulva, juvenile tail, and infective stage. Cross-mating trials support the integrity of the new species.The life cycle of M. camdenensis is closely synchronized with that of its primary host, S. tuberosum larvae. Infected S. tuberosum larvae were first collected in May. Emergence of postparasites from late instars took place from mid-June through mid-October. Sampling data indicate a lower susceptibility to infection among S. venuslum Say larvae.     

Ochoterenella esslingeri n. sp. (Nematoda: Onchocercidae: Waltonellinae) from Bokermannohyla luctuosa (Anura: Hylidae) in Minas Gerais,Brazil, with notes on Paraochoterenella Purnomo & Bangs, 1999

The waltonelline Ochoterenella esslingeri n. sp., a filarial parasite of the anuran Bokermannohyla luctuosa in Minas Gerais, Brazil is described. Several characters distinguish this new species from the 15 species presently included in the genus: the cuticular ornamentation of the female that is restricted to the posterior region of the body, the irregular arrangement of the small, rounded bosses, the postoesophageal vulva, the short glandular oesophagus, the size and shape of the microfilariae, the long left spicule and high spicular ratio. Irregularly arranged, tiny, rounded bosses are common in the monotypic genus Paraochoterenella from an Indonesian ranid, which is not well defined but likely valid. In the Neotropical Realm, the type hosts of the species of Ochoterenella are Hylidae (O. esslingeri n. sp.), Leptodactylidae (two species) and the remaining 13 species were described from the giant toad Rhinella marina (Bufonidae).     

Description of Hemicycliophora biosphaera n. sp. from Arizona (Nemata: Criconematidae)

Hemicycliophora biosphaera n. sp. (Nemata: Criconematidae) was found in soil from a fallow field plot within the Biosphere 2 Center, Oracle, Arizona. The nematode species is characterized by continuous and irregular breaks in transverse striae in the lateral field, smooth annules, a rounded-truncate lip region with rounded anterior margins, three lip annules, first labial annule elevated and widened laterally, dome-shaped and elevated labial disc, stylet length (76-97 (μm), VA%T value (30-59), 234-273 body annules, and tail with a terminus offset, cylindrical to slightly conoid digit. Hemicycliophora biosphaera n. sp. most closely resembles H. armandae but differs from it in body width (30-39 vs. 38-54 μm), stylet length (76-97 vs. 95-119 μm), greater number of annules between the excretory pore and esophagus base (4-16 vs. 2), length of the tail terminal spike (16-28 vs. 32 μm), lower Rvan value (9-15 vs. 16), and indistinct spetanatheca vs. distinct spermatheca.     

Description of Meloidogyne nataliei n. sp. (Nematoda: Meloidogynidae) from Grape (Vitis labrusca) in Michigan,with SEM Observations

Meloidogyne nataliei n. sp. is described and illustrated from grape (Vitis labrusca) in a declining vineyard at Mattawan, Michigan, USA. Infected grape roots exhibit no hyperplastic symptoms. Females protrude from the roots and are surrounded by a massive egg sac containing many eggs. This new species is distinguishable from other species of the genus especially by its large, striking perineal pattern with, usually, two ropelike separated striae on each side extending laterally from the vulval and anal areas. Among other diagnostic characters are the location of the female excretory pore adjacent to or near the base of the head and the heavy larval stylet averaging about 22 μm in length. Examination of males, females, and larvae with the scanning electron microscope confirmed observations made by optical microscopy and revealed diagnostic and other structures in greater detail. Of particular significance was the nature of the male head, with a massive circular labial disc on which is located a rectangular structure surrounding the oral opening, and the six distinct lips appearing as a rosette in en face view. The known distribution of this new species is presently limited to its original location in Michigan.     

Cochylis Treitschke in China: one new species and five new records (Lepidoptera,Tortricidae, Cochylini)

Six species of Cochylis Treitschke, 1829 are recorded for China. Among them, Cochylis triangula sp. n. is described as new; Cochylis atricapitana (Stephens, 1852), Cochylis discerta Razowski, 1970, Cochylis dubitana (Hübner, [1799]), Cochylis faustana (Kennel, 1919) and Cochylis posterana hyrcana (Toll, 1948) are recorded for the first time for China. The female of Cochylis discerta Razowski, 1970 is described for the first time. Adults and genitaliaare illustrated, a key is given for the identification of Chinese species based on male genitalia.     

Commensal Nematodes in the Glands,Genitalia, and Brood Cells of Bees (Apoidea)

Seven species of bees from the eastern United States, representing four families in the Apoidea, were dissected and examined for nematode associates. Dufour''s glands in females of Halictus ligatus, Augochlora pura mosieri, and Augochlorella gratiosa (Halictidae) from Florida were infested with dauer juveniles of Aduncospiculum halicti (Diplogasteridae). The Dufour''s glands of Colletes thoracicus (Colletidae) females from Maryland were infested with dauer juveniles of a new species of Koerneria sp. (Diplogasteridae), and abdominal glands of females of Andrena alleghaniensis (Andrenidae) from New York were infested with dauer juveniles of another new species of Koerneria. The lateral and median oviducts, Dufour''s glands, and poison sacs in females of Anthophora abrupta (Anthophoridae) from Maryland and Alabama were infested with dauer juveniles of a new species of Bursaphelenchus sp. (Aphelenchoididae). Cross sections of the nematode-infested poison sacs of A. abrupta revealed two types of humoral host defense reactions.     

Pratylenchoides hispaniensis n. sp. (Nemata: Pratylenchidae)

Pratylenchoides hispaniensis n. sp. is described and illustrated from a bisexual population found in a natural habitat at Santa Elena, Jaen, central Spain. Its main distinctive characters are very long esophageal gland lobe (81-117 μm; N'' = 51-71) overlapping the intestine 3 to 5 times the body width; lateral field with six incisures; stylet knobs sloping posteriorly; labial disc encircled by the irregular sectors of the first annule; tail cylindrical, extremity annulated, and frequently with a slight dorsal indentation of the hyaline portion at the end of the lateral field. Pratylcnchoides hispaniensis n. sp. appears closely related to P. megalobatus and P. nevadensis. It differs from the former primarily by its longer body length (761-998 vs. 430-621 μm), longer stylet length (20.5-24.4 vs. 18-21 μm), six incisures in the lateral field vs. four for P. megalobatus, and posteriorly sloping stylet knobs vs. rounded or anteriorly flattened knobs in P. megalobatus. It differs from P. nevadensis mainly by the shape of the stylet knobs (sloping in P. hispaniensis vs. rounded in P. nevadensis), length of esophageal lobe (81-117 vs. 34-82 μm), and position of esophageal gland nuclei (all posterior to esophago-intestinal junction in P. hispaniensis vs. at least one nucleus anterior to junction in P. nevadensis).     

Review of the species level taxonomy of the neotropical butterfly genus Oenomaus (Lycaenidae,?Theclinae,?Eumaeini)

Seven new species of the Neotropical hairstreak genus Oenomaus are described: Oenomaus mancha Busby & Faynel, sp. n. (type locality Ecuador); Oenomaus gwenish Robbins & Faynel, sp. n. (type locality Panama); Oenomaus lea Faynel & Robbins, sp. n. (type locality Ecuador); Oenomaus myrteana Busby, Robbins & Faynel, sp. n. (type locality Ecuador); Oenomaus mentirosa Faynel & Robbins, sp. n. (type locality Peru); Oenomaus andi Busby & Faynel, sp. n. (type locality Ecuador) and Oenomaus moseri Robbins & Faynel, sp. n. (type locality Brazil, Santa Catarina). For each new Oenomaus species, we present diagnostic characters and notes on its habitat and biology. We illustrate adults, genitalia, and distribution. New distributional and biological data are presented for 21 previously described Oenomaus species. Oenomaus melleus guyanensis Faynel, 2008 is treated as a new synonym of Oenomaus melleus melleus (Druce, 1907). Females are described and associated with males for ten species using a variety of factors, including mitochondrial COI DNA “barcode” sequences. We summarize the reasons why the number of recognized Oenomaus species has grown in the past decade from one species to 28 species. Finally, we overview the habitats that Oenomaus species occupy and note that the agricultural pest on Annonaceae, Oenomaus ortygnus, is the only Oenomaus species that regularly occurs in greatly disturbed habitats.
