A, A. gilberti is distributed throughout the Gulf of California, Mexico to the coastal waters of California, USA. Presently, it can be distinguished from its closest relative, A. esuncula (= Albula sp. C) from the tropical eastern Pacific, solely by differences in mitochondrial DNA (cytochrome b) gene sequences. No diagnostic external morphological characters have yet been found that can reliably separate the two distinct genetic lineages although some differences in placement of pelvic-fin tip relative to vent may exist. Differences detected in counts of mer-istic characters should be tested in larger series of specimens, especially of A. esuncula. Available evidence also suggests that .4. gilberti and A. esuncula show a parapatric distribution, with an area of sympatry in the southern Gulf of California. We also provide a description ofadults of A. esuncula (the original description was based solely on two larvae), review the current nomenclature of the subfamily Albulinae, and discuss the role and justification of using molecular data for diagnosing cryptic species.

Three trematodes, Parastrigea cincta Brandes,1888; Parastrigea diovadena Dubois & Macko, 1972, and Patagifer lamothei Dronen & Blend, 2008, one ces-tode Cyclustera ibisae Schmidt & Bush, 1972 and four acanthocephalan species Hexaglandula corynosoma Travassos, 1915, Arhythmorhynchus frassoni Molin,1858, Southwellina hispida Van Cleave, 1925, Ibirhynchus dimorpha Garcia-Varela, Perez-Ponce de Leon, Aznar & Nadler, 2011, were found. Four of these species were recorded for the first time in the white ibis, raising the number of helminth species thatparasitize this bird to 57 along its distributional range. Additionally, 4 of the helminth species are recorded in Mexico for the first time.

Among 2,103 soil samples collected from 12 provinces of China during 2008-2010, nine Longidorus species were identified based on morphological characters: L. henanus Xu & Cheng 1992; L. litchii Xu & Cheng 1992; L. hangzhouensis Zheng et al. 2001; L. pisi Edward, Misra & Singh 1964; L. macromucronatus Siddiqi 1962; L. fangi Xu & Cheng 1991;L. camelliae Zheng et al. 2000; L.jonesi Siddiqi 1962; and L. fursti Heyns et al. 1987. In this study, we compile new data on the distribution and hosts of Longidorus in China and the available historical records reported from China. Longidorus henanus has the most widespread distributionin China, while L. litchii is found only in Fujian province, and L. pisi is recorded for the first time in China. The hosts of the genus Longidorus in mainland China included 39 known and 3 unknown plant genera, all of which are perennial woody plants.No records were from cultivated annual crops.

The specimens were collected during the Nodinaut expedition on board the r/vI'Atalante in the summer of 2004. The new species belongs to the genera Stenotanais (S. arenasi) and Typhlotanais (T. froufesae, T. pereosetulosa). Stenotanais arenasi is believed to be the first male Stenotanais reported. A key to the genus Stenotanaisis presented. The anterior pleopods of T, pereosetulosa were found to be dissimilar from the posterior.
查看更多>>摘要：Four new mite species from the Crimean Peninsula (Ukraine), viz. Pulaeus leonidi sp. nov., P. maslovi sp. nov., P. semi-striatus sp. nov. and Lupaeus valentinae sp. nov. are described and illustrated. The female and male of Pulaeus krama (Chaudhri, 1977) are redescribed based on Crimean specimens. Pulaeus longignathos Bu & Li, 1987 syn. nov. and P. chongqingensis Bu & Li, 1987 syn. nov. are considered as the male and the female of P. krama, respectively. P. krama is recorded from Crimea for the firsttime. New nomenclatural combinations are proposed. Keys to species of the Pulaeus and Lupaeus of the Crimea are provided.
