查看更多>>摘要：Meghimatium is a group of terrestrial slugs distributed in Asia. 185 specimens were collected from Taiwan, China, Okinawa (Japan), Thailand and Malaysia. Phylogenetic analyses using concatenated DNA sequences of cytochrome C oxidase subunit 1,16S ribosomal RNA and nuclear 28S ribosomal RNA genes revealed that clades in the resulting molecular phylogeny of Meghimatium are largely congruent with taxa identified on the basis of their genitalia. Four monophyletic groups, i.e., the M. fruhstorferi, M. burchi, M. uniforme and M. striatum complexes, with moderate to strong statistical supports (86/53/0.98/66, 100/100/1.00/100,100/100/1.00/100,100/100/1.00/100) were identified. M.pictum is paraphyl-etic and is clustered with M. bilineatum to constitute an additional monophyletic group (100/100/1.00/100). Body size does not show an evolutionary trend either from small to large or vice versa, based on the phylogenetic tree. A new species, M. baoshanense sp. nov., is named based on the included specimens constituting a monophyletic group, its medium size (40.1-52.7 mm in body length) and its genitalia with 10-18 papillae at the lower end of the spermathecal duct where it connects to the uterus and vagina.

The new species is characterized by absence of prominent palpebral appendages and postocular swellings, males measuring 44.2 ±2.1 mm SVL (41.1-7.3 mm) and females 56.4± 2.8 mm SVL (52.7-59.8 mm), snout rounded in dorsal ,and obtuse in lateral views, dorsal skin uniformly rugose, with no elevated warts, and tympanum defined as a depression on the skin. The new species was found in Guapore river drainage, a highly impacted area due to the construction of water dams.

The new species clearly differs from F. chacei Holthuis, 1951 by carinated dactylus of majorpereiopod II (vs. flattened in F. chacei), more robust segments and feebly developed fingers of minor pereiopod II, and proportions of the distal segments of ambulatory pereiopod III. The holotype female of F. chacei Holthuis, 1951 and specimens from the type series are re-examined and re-described, based on specimens from the Pacific coast of Panama and Columbia.
查看更多>>摘要：The Hymenosomatidae is unique among the Brachyura on the basis of spermatozoal ultrastructure and morphological characters of the adults and larvae. The location of the hymenosomatid male gonopore, always a controversial question, is here shown to besternal, not coxo-sternal. This disposition, analogous to the arrangement of Thoracotremata, contradicts all morphological characters that indicate a heterotreme affiliation, close to the Majoidea and Dorippoidea. Molecular data also support such an assignment. The multiple hymenosomatid plesiomorphies are reviewed. The exceptional male reproductive system, a new scheme for the Eubrachyura, is assumed, at least in part, to be the result of a strong car-cinisation in an ancient, deeply rooted group, at present the most ecologically diverse in Brachyura. The presence of the Hymenosomatidae on the former Gondwanan landmasses and its worldwide pattern of distribution are consistent with the hypothesis of a Gondwanan origin of the family.

The species is distinguished from its congeners by its moderate size: SVL to maximum 108.5 mm, dorsal pattern of five to seven white vertebral blotches between nape and sacrum and six to seven pairs of short white bars on flanks between limb insertions, 1-4 internasals, 30-32 ventral scale rows between weak ventrolateral folds, 14-18 precloacal pores in males, 10-14 longitudinal rows of smooth dorsal tubercles, 14-16 broad lamellae beneath digit I of pes, 17-19 broad lamellae beneath digit IV of pes, and a single transverse row of enlarged tubercles along the posterior portion of dorsum of each tail segment.

This species was not previously recorded in the Republic of Panama, although two other invasive Eleutherodactylus species, E. antillensis Reinhardt & Liitken 18631862 and E. johnstonei Barbour 1914, have established populations within Panama City (Jaramillo et al. 2010). Based on standardized mitochondrial gene fragments, we report for the first time the presence of E. planirostris in Panama.
