Abstract— A new species, Espeletia ocetana (Asteraceae), from about 3500 m a. s. l. in Páramo de Ocetá, Mongua, Boyacá department, Colombia, is described and illustrated. The new species exhibits a caulescent rosette habit (0.7‐1.8 m tall), sessile leaves, elliptic leaf laminae with greyish indumentum, robust bracteate thyrsoid capitulescences spreading laterally from rosette, each holding 16‐37(‐69) capitula, external phyllaries 14.2‐31.1 mm long, and ray florets 13.9‐21.3 mm long arranged in 2.0‐2.9 series. It is markedly different from the majority of other members of the genus, and only slightly similar to E. jaramilloi, from which it can be easily distinguished by its taller stems, wider leaves with a smaller length/width ratio, and longer sheaths. Furthermore, E. ocetana has capitula with ray florets arranged in fewer series, and with longer phyllaries, ray corollas, ray corolla limbs, ray styles, ray style branches, disc florets, and disc styles. In addition, E. ocetana is distributed allopatrically in regard to E. jaramilloi, and differs as well in its ecological preference for humid to very humid shrubby páramos. Espeletia ocetana is rather abundant in its type locality, which is a relatively well-conserved páramo located within the limits of Parque Natural Regional Siscunsí-Ocetá. However, it is absent from road margins, abandoned agriculture fields, and other areas impacted by human activities. Further studies will be necessary to know appropriately the extent of the geographic distribution of E. ocetana, its ecological requirements and its phylogenetic affinities with other species.

Calathea gentryi H. Kenn., and C. yawankama H. Kenn., both endemic to Amazonian Peru, are described as new. Calathea gentryi occurs in Department Loreto in both Maynas and Alto Amazonas Provinces. Calathea gentryi is characterized by all basal leaves, a single, relatively small (4.5–7 × 1–2.5 cm) narrowly ellipsoid to subcylindric inflorescence of 12 to 19 spirally arranged small (1.1–1.5 × 0.9–1.2 cm) bracts, and three bracteoles per flower pair, two lateral, membranous, and a medial, claviculate, one. Calathea gentryi shares a similar habit and inflorescence morphology with C. barbata Peters. and C. schunkei H. Kenn. Calathea yawankama, known only from the type locality in Department Amazonas, is characterized by the relatively broad (length: width ratio 1.15–2.23:1), all basal leaves, leaves with the blades patterned with a light green band along the midrib adaxially, purple abaxially, and small (2–2.5 × 2–2.7 cm), globose, inflorescence of 12 to18 spirally arranged bracts, the presence of claviculate bracteoles and white flowers. Calathea yawankama shares a similar inflorescence morphology with C. compacta S. Suárez & Galeano and C. pearcei Rusby.

A New Species

Phytoseiid mites have received considerable world wide attention because of their potential as natural enemies of phytophagous mites (McMurtry, 1984). The Amblyseius obtusus group Chant  is the largest species group in the genus Amblyseius. Chant & McMurtry (2004) divided the group into seven subgroups based on spermathecal morphology. The andersoni subgroup of Chant & McMurtry, 2004 is characterized by a spermatheca with the calyx dish-, cup-, bell-, or V-shaped, with the length/width ratio at the mid-point of the calyx < 3:1. A total of 24 species of the andersoni subgroup are known from the Neotropical region, 13 of these from Brazil (Moraes et al., 2004). A new species of this subgroup, Amblyseius paulofariensis sp. nov., is described and illustrated in this paper, from specimens collected in the semi-deciduous forest area of “Estação Ecológica de Paulo de Faria”, a protected natural area in the State of São Paulo, southeastern Brazil, on three species of Euphorbiaceae: Acalypha diversifolia Jacq., Actinostemon communis (Müll. Arg.) and Alchornea glandulosa Poepp. & Endl.. In the region where this mites was found, the climate is of the type Cwa-Aw of Köppen, with two distinct seasons: one wet, from October to March, and the other dry, from April to September. The annual mean temperature is 25°C, with a maximum mean of 30°C and a minimum mean of 20°C (Barcha & Arid, 1971; Arid & Barcha, 1973).

A New Species

A new species of the genus Helmutkunzia Wells & Rao, 1976 (Miraciidae) is described from specimens collected from an intertidal sandy beach in Xiamen, Fujian Province, China. Helmutkunzia xiamenensis sp. nov. differs from its two congeners by the length/width ratio of the female P5 exopod, the number or length of the setae on the sexually dimorphic P2 endopod in the male and the relative length of the spines on the endopodal lobe of the male P5. The Chinese species is morphologically closest to H. variabilis Wells & Rao, 1987 from the Andaman and Nicobar island chain. Females of both species can readily be differentiated by the relative length of the P5 exopod while males can be differentiated by the length of the armature elements on P2 enp-2 and the endopodal lobe of P5. The genus Balucopsylla Rao, 1972 is reviewed, resulting in the proposal of Pseudobalucopsylla gen. nov. to accommodate the type species Balucopsylla triarticulata Wells & Rao, 1987 and three new Indo-Pacific species previously identified with it: P. obscura sp. nov. from the Andaman Islands, P. costaricensis sp. nov. from the Pacific coast of Costa Rica and P. mielkei sp. nov. from the Galápagos archipelago. A key to species of Pseudobalucopsylla sp. nov. is provided.

A new species of Boholina, B. ganghwaensis sp. nov. is described, based on specimens collected from burrows of the manicure crab, Cleistostoma dilatatum, in the tidal flat of Ganghwa Island in western Korea. The new species is closely similar to B. purgata and B. parapurgata by having a pointed process on the posterior angles of the second and third pedigerous somites and a similar rostrum in the female, but can be distinguished from its congeners by the following characters: in females by the genital double-somite with small hook-like process on each gonoporal plate, the setation of the distal endopodal segment of mandible, the basis and first endopodal segment of the maxillule incompletely separated, the inner distal spine/outer terminal spine length ratio on P5; and in males by the distal spine present on the posterior surface of the basis of both P5 and the length/width ratio of the endopod of the right P5. This is the first Bololina species recorded from the north-west Pacific.

A New Species

ABSTRACTObjective. The present contribution aims at the description of a new species of the genus Schizopera. Materials and methods. Water samples were collected in littoral areas with mangrove and macrophytes, and in the limnetic zone. Twenty five liters of water were taken. Water samples were filtered with a zooplankton net (45μm) and preserved in 70% ethanol. The filtered samples were concentrated to 100 ml and examined in a Bogorov camera. Copepods were separated. Observations and drawings of S. evelynae sp. nov. were made at a magnification of 1000X. Results. Schizopera evelynae sp. nov. seems to be closely related to S. giselae Jiménez -Álvarez 1988 and to S. pratensis Noodt 1958 based on the armature formula of P1-P4, but can be separated from these two species based on the relative length of P1ENP, length/width ratio of P1ENP2, relative length of the outer proximal and distal spines on P4EXP3, shape of the exopod and relative length of the exopodal setae of the female P5, shape and length/width ratio of the male P2ENP2, and male P5 baseoendopodal lobe:exopod length ratio. A key to the species of Schizopera from America is given. Conclusion. A new species of the genus Schizopera is described. The Colombian material shares most characters with S. giselae and S. pratensis.

A new species of the freshwater cyclopine copepod genus Diacyclops is described from a North American cave system in SE New Mexico, U.S.A. The new species, D. nikolasarburni n. sp., differs from its congeners by its having of a unique combination of characters including: 17-segmented antennules, three-segmented rami in legs 1-4, a basic 2333 spinal formula with a highly variable pattern, naked inner margin of caudal rami, but dorsal surface with spinules, subequal terminal spines of leg 4 endopod, and inner spine of fifth leg about as long as bearing segment. This species has also a variable length/width ratio of the caudal ramus (4.6-6.0, average 5.0); the lateral caudal seta is inserted on the distal one-quarter of ramus. The 2333 spinal formula was dominant (55%) in the population but other patterns were also present. The new species belongs to Group 1 species of Diacyclops (sensu Reid & Strayer, 1994). The local population of this stygobiotic species probably resulted from radiation-stranding processes of epigean forms of widely distributed Diacyclops and is probably endemic to this cave system.

A New Species

The genus Polyschides is characterized by smallto medium-sized shells with an apex divided into four lobes. We present a revision of the species of Polyschides from Brazil, with the description of a new species. Polyschides tetraschistus (Watson, 1879) and P. portoricensis (Henderson, 1920) were confirmed for Brazilian waters, with the known geographic distribution of the latter extended southward to the state of Rio de Janeiro (21ºS). Comparisons of shell morphometrics show that: (1) P. xavante n. sp. is significantly smaller and less arched than P. tetraschistus and P. portoricensis; (2) the maximum diameter, height and width of the anterior aperture, and the height and width of the apical aperture were also significantly smaller in P. xavante; (3) the maximum diameter in P. xavante n. sp. and P. tetraschistus is located closer to the aperture than in P. portoricensis. A Discriminant Function Analysis based on seven shell morphometric variables (length, maximum diameter, length to maximum diameter ratio, anterior aperture width, anterior aperture height to anterior aperture width ratio, maximum diameter to posterior aperture width and distance of point of maximum curvature from the apex to length ratio) were 100% efficient in discriminating among the three species.

Morphometrical Study

A new species of Cosmocercella as a parasite of the hylid frogs Diaglena spatulata and Triprion petasatus is herein described. The new species most closely resembles C. haberi and C. anothecae, both species distributed in Mexico. Cosmocercella diaglenae n. sp. differs from these species in the arrangement of the caudal papillae, and mainly in the presence and size of the first pair of papillae situated anteriorly to the anus, but it also differs by the distance between the second and third pairs of plectanes, by the length of the spicules and gubernaculum, by the size and form of the pharynx, as well as the esophageal bulb length-width ratio in females and finally by having larger eggs. In order to find additional taxonomic characteristics to distinguish among species, a morphometrical study was conducted.

A New Species

Species of the cyclopid genus Halicyclops are widespread in coastal, estuarine and even fluvial environments worldwide. On the Atlantic coast of South America several species have been recorded as far south as the state of São Paulo in Brazil, at about 24°25´S. Specimens belonging to this genus have been collected from plankton samples from Laguna de Mar Chiquita, a coastal lagoon on the Argentinean coast at 37°40' S, 57°19' W. These do not fit the diagnosis of any of the known species, and are here described as a new species. Both sexes of Halicyclops ramirezi sp. nov. are described and illustrated. It is distinguished by a combination of characters relating to (1) the last endopodal segment of P4, (2) shape and armature of P5, (3) size and spinulation of the spine on the basipodite of P1, and (4) length/width ratio of the fourth A1 segment. The presence of only one seta and three spines on the male P5 is also characteristic. The presence of Halicyclops glaber Rocha, 1983 is reported for the first time for Argentina in sediments of the same locality.

A New Species

The new species Pimpinella enguezekensis (Apiaceae) is described from Ağılbaşı village (Engüzek), Darende district in Malatya city (E of Turkey). It shows a unique combination of morphological characteristics concerning the size, shape and margins of leaves, the indumentum of petals and the morphology of fruits. It is related to Pimpinella species with entire leaves and yellow flower, such as P. flabellifolia, P. paucidentata, P. sintenisii and P. nephrophylla of section Reutera subsection Flabellifoliae. The new species is more closely related to P. flabellifolia, with which it shares some morphological similarities, but from which it is easily distinguished by its multi-stemmed habit, smaller rhomboid leaves with spiny dentate margins, glabrous petals, and smaller fruits lacking ribs. According to micromorphological studies, fruits of P. enguezekensis are glabrous and show reticulate striate surface. Furthermore, they also show remarkable anatomical differences with regard to fruits of P. flabellifolia, the commissure width in P. enguezekensis being more than twice smaller than in P. flabellifolia and the mericarp length/width ratio in P. enguezekensis being also smaller than in P. flabellifolia. An identification key of the yellow-flowered species with entire leaves is reported. Moreover, a distribution map for P. enguezekensis and other Turkish yellow-flowered related species is presented.
