Two New Species

A new genus, Campodesmoides gen. nov., is described to only encompass C. corniger sp. nov., from Cameroon. This genus and species is distinguished from the few known species of the small western African family Campodesmidae, all currently in Campodesmus, by the much longer antennae and legs, the normal pore formula with ozopores borne on porosteles, and the suberect and distally twisted gonopod, coupled with peculiar horns on a few anterior postcollum segments. A new Campodesmus is also described, C. alobatus sp. nov., from Ivory Coast, which differs from congeners primarily in the lack of a dorsal/lateral lobe on the otherwise usual and strongly subcircular gonopod telopodite, albeit the latter is not directed mesad, but held subparallel to the main body axis.

Two New Species

A new genus, Lukea Gosline & Cheek (Annonaceae), is erected for two new species to science, Lukea quentinii Cheek & Gosline from Kaya Ribe, S.E. Kenya, and Lukea triciae Cheek & Gosline from the Udzungwa Mts, Tanzania. Lukea is characterised by a flattened circular bowl-shaped receptacle-calyx with a corolla of three petals that give the buds and flowers a unique appearance in African Annonaceae. Both species are extremely rare shrubs of small surviving areas of lowland evergreen forest under threat of habitat degradation and destruction and are provisionally assessed as Critically Endangered and Endangered respectively using the IUCN 2012 standard. Both species are illustrated and mapped. Material of the two species had formerly been considered to be possibly Uvariopsis Engl. & Diels, and the genus Lukea is placed in the Uvariopsis clade of the Monodoreae (consisting of the African genera Uvariodendron (Engl. & Diels) R.E.Fries, Uvariopsis, Mischogyne Exell, Dennettia Bak.f., and Monocyclanthus Keay). The clade is characterised by often conspicuous, finely reticulate quaternary nervation and incomplete or absent connective shields (in Annonaceae the connective shield is usually complete). Morphologically Lukea is distinct for its broad, turbinate, fleshy pedicel, a synapomorphy. It appears closest to the West African monotypic Monocyclanthus, sharing a trait unusual in the Annonaceae: the calyx in both genera forms a shallow bowl (calyx lobes are absent or vestigial), barely enclosing the base of the petals at anthesis, and persisting as a living, leathery disc at least until the fruit is mature. The placement of Lukea within the Uvariopsis clade is discussed.

Occigamasus n. gen., O. lindquisti n. sp. and O. makarovae n. sp. from Vancouver Island (Canada) and Oregon (U.S.A.) are described. Five other new species and their sites are noted but not enough specimens were available for adequate descriptions. Cycetogamasus californicus (Banks) sensu Hennessey and Farrier, 1988 is transferred to Occigamasus as a new combination.

Two New Species

The present paper contains descriptions of two new species and one new genus: Latinopsis patagonica gen. nov., sp. nov., and Candona quasiincarum sp. nov. Both species were collected during a two-month Franco-Chilean expedition to Madre de Dios archipelago in January and February 2006. The following new systematic arrangements are proposed: L. anisitsi (Daday, 1905) comb. nov., L. columbiensis (Mehes, 1914) comb. nov., and L. falclandica (Vavra, 1898) comb. nov. Latinopsis anisitsi is redescribed from the type material and a lectotype is designated. Two species are excluded from the subfamily Candoninae, one of which is Danielocandona albida (Sars, 1901). After examination of the type material the species is reclassified as Neocypridopsis albida (Sars, 1901) comb. nov. A checklist of the known species of Candoninae of South America and the West Indies is provided.

A new genus Loveninema gen. n., with two new species L. tubulosa gen. n., sp. n. and L. unicornis gen. n., sp. n. is de-scribed from bottom sediments collected in Skagerrak off the west coast of Sweden. Loveninema gen. n. is unique amongother genera of Plectida by possessing a midventral labial projection located on the ventral edge of the oral opening andprotruding anteriorly. Other diagnostic characters include: sclerotised labial framework in the shape of a conoid ring withthree projections extending posteriorly: one mid-dorsal, one left-subventral and one right-subventral; papilliform outer la-bial and cephalic sensilla; amphidial fovea a transverse slit located anterior to cephalic sensilla bases; excretory pore open-ing on the ventral side of the labial region; pharynx uniformly muscular, cylindrical; female reproductive systemdidelphic, amphidelphic; male reproductive system monorchic, with reflexed testis; spicules present; gubernaculum pres-ent or absent; either alveolar or tubular supplements present in males, absent in females; caudal glands and spinneret pres-ent. L. tubulosa gen. n., sp. n. is particularly characterised by the 0.66–1.12 mm long body; short midventral labialprojection; straight vagina without sclerotisations; male without alveolar and with 12–15 tubular supplements, 15.0–21.5µm long spicules, and with gubernaculum. L. unicornis gen. n., sp. n. is particularly characterised by the 0.65–0.98 mmlong body; long midventral labial projection; straight vagina without sclerotisations; male with up to 20 alveolar and without tubular supplements, 11.5–14.0 µm long spicules, and without gubernaculum.

AbstractThe Simulium sanctipauli Vajime & Dunbar subcomplex of the West African S. damnosum Theobald complex is cytotaxonomically revised for the western part of the Onchocerciasis Control Programme area. The subcomplex is defined and a chromosomal key provided for the identification of the sibling species and forms recognized. Two sibling species are newly described, S. leonense Boakye, Post & Mosha (Sierra Leone) and S. konkourense Boakye, Post, Mosha & Quilleévéré (Guinea and Sierra Leone). Detailed chromosomal data are provided as warranty for the conclusions about the specific or infraspecific status of the taxa recognized.

A list of and key to Phaneroptera from China is provided. One new species with comparatively short hind wings, Phaneroptera brevicauda sp. nov. is described. And a new small-sized genus and new species Anormalous zhangi sp. gen. & nov. is also described here. The new genus most resembles the genera in the tribe Ducetiini in shape of lateral lobe of pronotum, structure of the tympana, shape of fore tibiae, and male subgenital plate without styli, but differs by the special tegminal structure. Both new species are distributed in southwestern China. Necessary illustrations are provided.
