Eight new species of Neotropical Zanthoxylum L. (Rutaceae) are here described based upon their morphological characters. Zanthoxylum amplicalyx Reynel, which belongs to Zanthoxylum sect. Tobinia (Desv. ex Ham.) Griseb., has the largest calyx segments for its section. The others, Z. brisoferox Reynel, Z. chocoense Reynel, Z. impressocordatum Reynel, Z. magnifructum Reynel, Z. mauriifolium Reynel, Z. sambucirhachis Reynel, and Z. tingana Reynel, belong to the most speciose section, Macqueria Comm. ex Triana & Planch., and are distinguished by a variety of characters. Zanthoxylum magnifructum has the largest fruits of any species in the genus in the New World. Of the newly recognized species, four have a geographical distribution in Ecuador, three in Colombia, and one in Cuba.

Comprehensive Account

Since the publication of the comprehensive account of the genus Nicotiana by Goodspeed and his collaborators (1954), extensive collecting by the author has revealed the existence of a number of undescribed species and has resulted in the compilation of data which allow a better understanding of specific relationships between those previously known. In this paper the morphological characters by which species can be recognized are discussed, and five new species and two new subspecies are described. Two of the new species proved to have 23 pairs of chromosomes, thus filling a gap in the series of from 16 to 24 pairs which, with the exception of 17 pairs, has now been recorded for the Australian taxa. Notes on the relationships, the more important morphological features, and the geographical distribution are provided for all previously recognized species.

A New Species

Morphological characters of well-established taxonomic utility are infrequently examined for their relative phylogenetic consistency. Second only to characters of reproductive anatomy, jaw morphology and dentition commonly are employed as diagnostic characters for hirudiniform leeches, yet these features are highly variable across the group. Patterns of change were investigated for number of jaws and number of denticles per jaw in a phylogenetic context across 17 hirudiniform leeches representing three families. Phylogeny reconstruction employed 16 morphological characters, as well as two nuclear and two mitochondrial loci, and was evaluated with parsimony and likelihood. Rather than constrain the ancestral number of denticles to extant states, this meristic was optimised with squared-change parsimony. The degree to which dentition patterns were explained by phylogenetic relationships was assessed against a null distribution defined by permutation of extant states across terminals. Dentition was found to be non-randomly explained by phylogeny and, thus, corroborative of relationships among hirudiniform leeches as well as of the uniqueness of a new species of Oxyptychus described here from the Peruvian Amazon.

Species Groups

The taxonomy of the New World species of Polyplectropus (Ulmer, 1905a) is revised to include detailed male and female diagnoses, descriptions, illustrations, distribution records, and keys to males of all species and species groups. A phylogenetic analysis based on 59 morphological characters, 89 of 92 (97%) New World Polyplectropus species, and 2 outgroup taxa was inferred using parsimony and Bayesian methods, which resulted in minor topological differences. Conflicting estimates of relationship among and within most species groups led to a less resolved Bayesian tree (vs. parsimony tree) due to high variation in rates of change among characters and an overall low number of characters. A new classification for New World Polyplectropus is proposed with revised characterization of 10 recognized species groups, 6 newly established. Four species remain unassigned to species group. A key to genera of New World Polycentropodidae, including a redescription of Polyplectropus is provided. The homology of the male genitalia of Polyplectropus is discussed. Ninety-two species are treated. The following 39 new species are described: Polyplectropus adamsae (Peru), P. alatespinus (Brazil), P. amazonicus (Brazil), P. andinensis (Argentina, Bolivia), P. blahniki (Venezuela), P. bolivianus (Bolivia), P. brasilensis (Brazil), P. brborichorum (Ecuador), P. cressae (Venezuela), P. colombianus (Colombia), P. corniculatus (Peru), P. cuzcoensis (Peru), P. ecuadoriensis (Ecuador), P. flintorum (Venezuela), P. gaesum (Brazil), P. guyanae (Guyana, Venezuela), P. hollyae (Brazil), P. hystricosus (Brazil), P. insularis (Panama), P. juliae (Brazil), P. kanukarum (Guyana), P. maculatus (Venezuela), P. manuensis (Peru), P. matatlanticus (Brazil), P. minensium (Brazil), P. novafriburgensis (Brazil), P. peruvianus (Peru), P. petrae (Brazil), P. pratherae (Brazil), P. puyoensis (Ecuador), P. robertsonae (Bolivia), P. rodmani (Brazil), P. rondoniensis (Brazil), P. tragularius (Brazil), P. tripunctatum (Peru), P. venezolanus (Venezuela), P. woldai (Panama), P. zamoranoensis (Honduras), and P. zuliae (Venezuela). Polyplectropus buchwaldi (Ulmer, 1911) is designated as a nomen dubium.Key words: phylogeny, taxonomy, Neotropics, Nearctric, Bayesian methods, parsimony, classification, cladistics, morphology, Trichoptera, Polycentropodidae, Polyplectropus, new speciesThe polycentropodid caddisfly genus Polyplectropus Ulmer contains 219 species found primarily in the tropical and subtropical regions of the world, with 125 species recorded from the Oriental biogeographic region, 53 from the Neotropical region (6 species extending their ranges into the Nearctic region), 37 from the

A New Species

Hedysarum nallihanse, a new species in the Hedysareae DC. (Fabaceae) tribe, was described and illustrated from Beypazarı-Nallıhan (Ankara Province) in Turkey. It belongs to the Obscura B. Fedtsch section. The characteristic structure has greenish stems, persisting corolla during fruiting time, mostly 2–3 unarmed, segments with short adpressed hairy fruit. The new species is closely related to H. vanense Hedge & Huber-Morath (1969:36) , but it is distinguished from it by a white corolla and the appearance of a purplish point at the tip and the larger stipule. Also, it is closely related to H. hedysaroides (L.) Schinz & Thellung (1913:70) since the standard is shorter than the keel and the fruit is without thorns. However, it is distinguished by its structure with a shorter stipule in this new species, the white color of the corolla, the segmented lomentum is 2–3 (not 3–5) and the leaflets 3–5 (–6) pairs (not 6–10 pairs). This new species is one of the two species in the genus that have a white corolla. Taxonomic descriptions, other morphological characters, phenology, and the IUCN category of the new species were presented. In addition, the geographical distribution of H. nallihanse, H. vanense and H. hedysaroides was mapped.

Florida is among important marine biodiversity areas with high richness and endemism of marine taxa. Despite the economic and scientific importance of the region, knowledge on the diversity and distribution of some groups, such as calcareous sponges, is still reduced and scattered in old literature. In the present work, sponges collected in the Florida Keys were studied under an integrative perspective (traditional morphology and DNA: ITS). Three calcinean species were found: Clathrina smaragda sp. nov., C. lutea, and Ernstia rocasensis. Clathrina smaragda sp. nov. is the first Clathrina described with a green cormus. The occurrence of C. lutea in Florida was confirmed, and E. rocasensis had its geographical distribution widened from the Northeastern Brazilian waters to Florida, although Floridian individuals of this species have presented differences in morphological characters that resulted in the proposition of a new diagnosis and a discussion on morphological plasticity in Clathrinidae. A complete list of the calcareous sponges from Florida is presented and their distributional patterns are discussed.

The New World species of Craspedochaeta Czerny, 1903 are revised and the first New World representative of the C. biseta group (C. argoniae spec. nov.) is described from Ecuador and Bolivia. Ten new species (C. amazonensis spec. nov., C. apsilutea spec. nov., C. candida spec. nov., C. chela spec. nov., C. feminea spec. nov., C. melanosoma spec. nov., C. pacaraima spec. nov., C. pollostos spec. nov., C. protomis spec. nov., C. weemsi spec. nov.) are described from the C. transversa species group and eight new species (C. biloba spec. nov., C. brunneivibrissa spec. nov., C. chauliodon spec. nov., C. loreto spec. nov., C. phaios spec. nov., C. pullipleura spec. nov., C. xanthonotum spec. nov., C. zongo spec. nov.) are described from the C. concinna species group. Craspedochaeta basalis brasiliensis Sóos, 1961 syn. nov. and C. piceoflava (Sóos, 1962) syn. nov. are synonymized with Craspedochaeta annulipes (Johnson, 1913) comb. nov.; C. minuta Sóos, 1962 syn. nov., C.atra (Kertesz, 1903) syn. nov. and C. albohalteria Sóos, 1962 syn. nov., are synonymized with C. concinna (Williston, 1896). Craspedochaeta sasakawai nomen nov. is provided as a replacement name for C. pleuralis (Curran, 1936), which is a junior homonym of C. pleuralis (Williston, 1896) comb. nov. Agonistic behaviour is recorded for the first time in Craspedochaeta, with photographs showing male-male interactions in the Bolivian species C. pullipleura. A key is provided for all 31 New World Craspedochaeta species and the relationships of the C. concinna and C. transversa groups are discussed on the basis of male and female morphological characters. Species of Craspedochaeta are recorded for the first time in North America, with C. weemsi found in Florida, C. concinna found in Florida and New Mexico, and C. annulipes found in Georgia, Maryland, Mississippi, North Carolina, and Texas.

The Neotropical thynnine genus Scotaena is revised and a cladistic analysis is presented. The analysis, conducted from 75 morphological characters of 31 terminal taxa, returned a single tree under equal weighting. The monophyly of Scotaena was not recovered. Three new genera and five new species are described: Kaysara gen. nov., Pseudoscotaena gen. nov. and Pampathynnus gen. nov., Scotaena reversa sp. nov., Kaysara laterolata sp. nov., Kaysara apiciconcava sp. nov., Kaysara marginoplicata sp. nov. and Kaysara levicrenata sp. nov. Three species are transferred to other genera as follows: Eucyrtothynnus rosenbergi (Turner, 1910) comb. nov., Glottynoides genisei Kimsey, 1991 comb. nov., Ornepetes clypearis Durán-Moya, 1941 comb. nov. Scotaena now comprises four species: S. trifasciata Klug, 1810; S. horni (Turner, 1927); S. vetusta Turner, 1909; and S. reversa. An identification key and geographical distribution maps for the studied species are also provided.
