A New Species

Dasybranchetus pacifica, collected in Concepcion Bay, Baja California Sur, Gulf of California, is described as a new species. In addition, the type species of the genus, Dasybranchetus fauveli Monro, 1931, is redescribed based on type material. The new species differs from D. fauveli in the absence of branchiae, the begining of the mid-dorsal lobe from chaetiger 2 instead of chaetiger 9, abdominal segments with well-developed neuropodial lobes, and hooded hooks with a main fang and three rows of subapical teeth in the following arrangement: 4 teeth in the basal line, 3 in the middle line, and 2 in the apical line.

Gobiesox lanceolatus is described from a single specimen collected from 300 meters depth in the Los Frailes submarine canyon in the southwestern Gulf of California. The "Canyon Clingfish" is unique within Gobiesox in having a lanceolate caudal fin, with the central rays longer than those above and below them. It is also distinguished by 14 dorsal-fin rays (first tiny and unsegmented), 11 anal-fin rays, 28 pectoral-fin rays, anus slightly closer to anal-fin origin than to posterior margin of pelvic disc, and dorsal-fin origin in front of vertical from anus. It is most similar to Gobiesox eugrammus, known from Isla Guadelupe, the coast of outer Baja California and southern California. This is the deepest record for a species of Gobiesox and only four other species of clingfishes are known from greater depths.

A New Species

AbstractThe type material of most European nominal species previously placed in Rhoptromeris and of some other species is studied. Notes are given on the type material, 10 lectotypes are designated and the identity of the species is discussed. Three valid Rhoptromeris species are found: R. heptoma (Hartig) [type species], R. villosa (Hartig) and R. rufiventris (Giraud) n.comb. The latter is the type species of Hexamerocera Kieffer which is synonymized with Rhoptromeris. The genus Rhoptromeris is described and compared with related genera. The three species found to be valid are figured and redescribed, and also a new species, R. nigriventris, is described from Sweden. R. heptoma is an important parasitoid of Oscinella frit (L.) (Dipt.: Chloropidae).

A New Species

The harvestman genus Bonea Roewer, 1914 and its type species B. sarasinorum Roewer, 1914 are redescribed based on the type material. In addition, two new species of Bonea from Hainan Island, China, are described and illustrated: B. zhui sp. nov. and B. tridigitata sp. nov. A new species of Lomanius Roewer, 1923 from Yunnan Province, China, is also described and illustrated: L. bulbosus sp. nov.. Keys to the 10 species of Bonea and the six species of Lomanius are provided. Paralomanius Goodnight & Goodnight, 1948 is revalidated from the synonymy of Lomanius, carrying as junior synonym Eulomanius Roewer, 1949, and containing two species from Micronesia (Paralomanius longipalpus Goodnight & Goodnight, 1948) and Philippines (Paralomanius mindanaoensis (Suzuki, 1977) new status). Bonea is transferred from the Ibaloniinae to Podoctinae. These are the first records of named species of Podoctidae from China.

A new species of Polynema Haliday from the newly defined pallidiventre species group of Polynema (Doriclytus Foerster), P. (D.) nupogodi sp. n., is described from Argentina and the only other species in this new group, P. (D.) pallidiventre (Ogloblin), is redescribed. A key to the two species of this group is provided.

A New Species

A new species of the spider genusLoxoscelesHeineken & Lowe, 1832,Loxoscelesmalintzisp. n., is described from the states of Puebla, Morelos and Guerrero, in the central region of Mexico. The description is based on adult males and females with morphological and ultra-morphological images. Updated distribution maps are provided for the 39 species recorded from the Mexican territory (including the new species). The states with the greatest diversity are Baja California Sur, Baja California and Sonora, with five species each. A total of 441 records for the 39 species, based on arachnological collections, data bases and literature, were used to update the distribution maps.LoxoscelesbonetiGertsch, 1958 is the species with the highest number of records in Mexico, with a total of 58 records from different localities. The states with the most records so far are Guerrero, with 55 records, Morelos, with 35 records, and Baja California Sur, with 30 records.Loxoscelesrufescens(Dufour, 1820), an introduced species, is recorded for the second time in Mexico, from the state of Chihuahua, being the first well-documented record for the country. Mexico has the greatest diversity of species ofLoxoscelesworldwide, with 39 (two introduced species) of the 134 described species. Additionally, biogeographical comments for the species from Mexico are provided.
