A new species of <Emphasis Type="Italic">Dioscorea</Emphasis> (Dioscoreaceae) from Central Cuba

Dioscorea pseudocleistogama from the Guamuhaya Massif in central Cuba is described and illustrated. The species is assigned to Dioscorea section Rajania. It can be distinguished from other species of section Rajania by its staminate inflorescences possessing racemes of sessile to subsessile cymes bearing narrowly-tubular staminate flowers with strongly imbricate ligulate tepals, and pollen with the exine rugulate.     

A new <Emphasis Type="Italic">Maxillariella</Emphasis> (Orchidaceae: Maxillariinae) from Costa Rica and Panama

Maxillariella prostrata, a new species from Costa Rica and Panama is described and illustrated. This species is similar to M. acervata but differs in having a prostrate habit, elliptic leaves up to 2 cm long, pseudobulbs with two unequal apical leaves, one larger and the other smaller, a red-spotted lip, the column apex entire, and the pollinarium made up of two small globose pollinia on an oblong stipe. Maxillariella prostrata also resembles M. dichaeoides from Ecuador and Peru but differs in having yellow to white flowers spotted with red, and the lip with a well-defined callus.     

<Emphasis Type="Italic">Myrcia incompleta</Emphasis> (Myrtaceae), a new species from Amazonian Brazil

Myrcia incompleta, from the northern Brazilian states of Amazonas and Rondônia, is described and illustrated. This species is apparently related to Calyptranthes paniculata and C. speciosa, from which it is distinguished mainly by its narrower leaves with midvein strongly raised adaxially and shorter, pauciflorous inflorescences. Conservation status for the species is proposed.     

Revision of the <Emphasis Type="Italic">Serrulati</Emphasis> species of <Emphasis Type="Italic">Penstemon</Emphasis> section <Emphasis Type="Italic">Saccanthera</Emphasis> subsection <Emphasis Type="Italic">Serrulati</Emphasis>

A revision of Penstemon sect. Saccanthera subsect. Serrulati includes a new species (P. salmonensis), a new variety (P. triphyllus var. infernalis), and the elevation of a subspecies to species (P. curtiflorus), bringing the total number of species to eight, which are keyed and described, complete with nomenclature and type citations.     

Three new species of <Emphasis Type="Italic">Davilla</Emphasis> (Dilleniaceae) from Bahia,Brazil

Three new species of Davilla (Davilla sessilifolia, Davilla minutifolia and Davilla aymardii) from Bahia, Brazil, are described and illustrated. Affinities and diagnostic characteristics of each species are discussed. The new species belong to Davilla sect. Homalochlaena.     

New and little-known crickets of the subfamily Phalangopsinae (Orthoptera,Gryllidae). 11. The genus <Emphasis Type="Italic">Parendacustes</Emphasis> (Part 2)

Discussions concerning the composition of the genus Parendacustes Chop., in particular, its subgenus Minizacla Gor., are continued. Eleven new taxa of this subgenus are described: P. trusmadi sp. n., P. mulu sp. n., P. brevispina sp. n., P. modispina sp. n., P. longispina sp. n., P. forficula sabah subsp. n., P. doloduo sp. n., P. buton sp. n., P. pallescens sp. n., P. kendari sp. n., and P. lindu sp. n. New data on P. makassari Gor. are also provided.     

Two new species of <Emphasis Type="Italic">Gentianella</Emphasis> (Gentianaceae) from Peru

Two new species of Gentianella (Gentianaceae, Gentianeae, Swertiinae), G. grantii and G. wayqecha, are described from Departamento Cusco, Peru. These two species differ from other Peruvian species of Gentianella in a combination of stems 10–100 cm long; no rosette of basal leaves; cauline leaves 10–75 mm long; flowers in thyrses; and corollas 14–26 mm long, campanulate, and adaxially glabrous. The leaves of G. grantii consist of an appressed pseudopetiole and a spreading, narrowly elliptic-oblong to linear blade; the corollas are lavender; and the corolla lobes are 0.6–0.7× as long as the tube. Gentianella grantii is similar to G. lythroides, of Bolivia, but differs in having more closely spaced leaves and less deeply lobed corollas. The leaves of G. wayqecha are sessile, lanceolate to ovate; the corollas are rose-violet; and the corolla lobes are 0.75–1.35× as long as the tube. Gentianella wayqecha is similar to G. rapunculoides, of Colombia and Ecuador, and G. ruizii, of Peru, but differs from both in its adaxially glabrous corollas and from G. rapunculoides in its less deeply lobed corollas. Both G. grantii and G. wayqecha grow in moist habitats near tree line, and are known only from a area northeast of the city of Cusco.     

A Review of the Fauna of the Planthopper Family Lophopidae (Homoptera,Fulgoroidea) from Vietnam with Descriptions of New Genera and Species and with Taxonomic Notes

Six new species are described from Vietnam, Apia simplexsp. n., Bisma angulatasp. n., Pitambara trypetoidessp. n., Sarmatoca cathemerinagen. et sp. n., Maracota soulieraegen. et sp. n., and Serida castaneasp. n., and Zeleja thoracalissp. n. from Malaysia. Two new genera, Maracotagen. n. (type species M. soulierae sp. n.) and Sarmatocagen. n. (type species S. cathemerina sp. n.), and a new subgenus Zelomachasubgen. n. (type species Zeleja thoracalis sp. n.) in the genus Zeleja are erected. The genus Binaluana Soulier-Perkins et Stroiński is downgraded to a subgenus of Zeleja Melichar. The genus Silvispina Wang et Soulier-Perkins with an uncertain systematic position is attributed to the subfamily Lophopinae and the tribe Lophopini. The placement of the genus Elasmoscelis Spinola (and, correspondingly, the tribe Elasmoscelini) in the subfamily Menoscinae, the genus Epiptyxis Gerstaecker in the tribe Menoscini, and the genus Jivatma Melichar in the tribe Lophopini is substantiated. New records of 11 species are given from Vietnam, some being first records for this country.     

New Taxa and Host Associations of the Weevil Subfamily Ceutorhynchinae (Coleoptera,Curculionidae) from Thailand

A new subgenus of Mecysmoderes Sch., Enzoellus Korotyaev, subgen. n. (type species Mecysmoderes carinatus Faust), two new genera of the tribe Hypohypurini Colonnelli, Siamohypurus Korotyaev, gen. n. (type species S. samuelsoni Korotyaev, sp. n.), Glikmanellus Korotyaev, gen. n. (type species G. rosti Korotyaev, sp. n.) and eleven new species of the weevil subfamily Ceutorhynchinae are described: Mecysmoderes (Memecyderes) sarukhanovi Korotyaev, sp. n. from Thailand, M. (Enzoellus) gressitti Korotyaev, sp. n. from Thailand and Laos, M. (Enzoellus) muratovi Korotyaev, sp. n., Megahypurus oroszi Korotyaev, sp. n., Cyphohypurus suppantschitschi Korotyaev, sp. n., Siamohypurus samuelsoni Korotyaev, sp. n., S. attilai Korotyaev, sp. n., Glikmanellus rosti Korotyaev, sp. n., all from Thailand; G. baloghi Korotyaev, sp. n. from Sri Lanka; G. obrieni Korotyaev, sp. n. and G. louisae Korotyaev, sp. n., both from India. A key to three species of Megahypurus from Thailand is given. Host plants are determined for Megahypurus alexandri Kor. and Glikmanellus rosti sp. n. from Koh Kood Island in southern Thailand, which were repeatedly collected from a tree of the family Rubiaceae.     

A new long-leaved species of <Emphasis Type="Italic">Asplundia</Emphasis> (Cyclanthaceae) from Colombia

A new species of Asplundia from the Cordillera Central in Colombia is described and illustrated. Asplundia callejasii is placed in A. subg. Asplundia, based on the morphology of the staminate flowers. The most distinctive characteristic of A. callejasii is its long leaves, with the blade unicostate, oblanceolate, shallowly divided, and very lustrous, with the plicate nerves forming roughly 45° angles with the midrib. These features give it a unique aspect that sets it apart from any other species within the family.     

Three new species of <Emphasis Type="Italic">Passiflora</Emphasis> subgenus <Emphasis Type="Italic">Decaloba</Emphasis> (Passifloraceae) from Brazil

Three new species from Brazil are described and illustrated. Passiflora cervii, P. jiboiaensis, and P. transversalis all belong to Passiflora subg. Decaloba.     

New Data on the Taxonomy of the Weevil Subgenus <Emphasis Type="Italic">Caucasoplinthus</Emphasis>, Genus <Emphasis Type="Italic">Plinthus</Emphasis> (Coleoptera,Curculionidae)

The taxonomic composition of the subgenus Caucasoplinthus Davidian, 1995 is revised. The immunis and granulosus groups are downgraded to subgroups of the silphoides and fallax groups, respectively; the voriseki subgroup is transferred from the fallax to the fausti group. Plinthus attilai Davidian et Savitsky, sp. n. and P. ljudae Davidian et Savitsky, sp. n. are described from Turkey and Abkhazia, respectively. New data on the taxonomy, distribution, and ecology of some little-known species are presented. The following new synonymy is established: Molytes vittatus Motschulsky, 1839 (= Meleus irroratus Reitter, 1884, syn. n., = Meleus faldermanni Faust, 1884, syn. n., = Meleus difficilis Faust, 1884, syn. n.).     

Revision of the carabid genus <Emphasis Type="Italic">Meroctenus</Emphasis> Gemminger et Harold,with a new status of <Emphasis Type="Italic">Xenodochus</Emphasis> Andrewes (Coleoptera,Carabidae: Harpalini)

Originally described as a monotypical genus with unclear taxonomic position from Sudan, Meroctenus Gemminger et Harold, 1868 is treated as a polytypical genus of the Selenophori genus group with two subgenera: Meroctenus s. str. and Xenodochus Andrewes, 1941, stat. n. (the latter was previously considered a distinct genus). Within Meroctenus, two species are recognized: M. (Meroctenus) crenulatus Chaudoir, 1843 (type species) and M. (M.) mediocris (Andrewes, 1936), comb, n., transferred to Meroctenus s. str. from Xenodochus. A new subspecies M. (M.) crenulatus orientalis subsp. n. is described from Pakistan. Diagnoses of the genus Meroctenus in new interpretation as well as of its two subgenera are discussed, and a taxonomic review of the subgenus Meroctenus s. str. with a key to the species and subspecies is provided. The following synonymy is proposed: Meroctenus Gemminger et Harold, 1868 = Paregaploa Müller, 1947, syn. n.; Meroctenus crenulatus (Chaudoir, 1843) = Egaploa (Paregaploa) conviva Müller, 1947, syn. n. Lectotypes are designated for Ctenomerus crenulatus Chaudoir, 1843 and Xenodus mediocris Andrewes, 1936.     

Two new species of <Emphasis Type="Italic">Arachnothryx</Emphasis> (Rubiaceae) from Oaxaca,Mexico

Two new species of Arachnothryx (Guettardeae, Rubiaceae) from the cloud forest of the Sierra Norte of Oaxaca, Mexico are described and illustrated. Arachnothryx axillaris together with A. heteranthera are the only two species in the genus with axillary inflorescences, but otherwise they are not similar. The new species is more similar to A. capitellata, but it differs in pubescence and inflorescence morphology. Arachnothryx flores-olverae can be confused with A. buddleioides mainly because they share discolorous leaves with densely tomentose pubescence, but they differ in stipule and inflorescence morphology. With these two new species the Sierra Norte of Oaxaca becomes more evidently the main hotspot of species diversity for the genus.     

An undescribed and overlooked species of <Emphasis Type="Italic">Sloanea</Emphasis> (Elaeocarpaceae) from the Ecuadorian Amazon

A new and rare species collected in Amazonian Ecuador, Sloanea jaramilloi, is described, illustrated, and its morphological similarities with other species of Sloanea is discussed. It resembles S. geniculata but is distinguished by the absence of persistent, adaxially concave stipules in the young branchlets, 4–6 sepals not covering entirely the reproductive organs of the flower, entire leaves, and the large, rigid, stout bristles sparsely distributed on the fruits.
