Summary Phasmarhabditis quinamensis sp. n. was recovered from several tropical terrestrial gastropod species collected in Cat Tien National Park in southern Vietnam with the snail, Sesara sp., designated as the type host. Phasmarhabditis quinamensis sp. n. is recognised by males and females with a lip region set off by the circle of six triangular low probolae, three bilobed, separated lips, stoma nearly as wide as long, the first genital papilla in males not incorporated into the bursa, the ensheathed dauer juveniles more than 1 mm long and with two circles of papillae at the head end and prominent amphidial apertures, a long filamentous tail and, when exsheathed, with a short, conical tail ending with two tiny spikes. The head structure of P. quinamensis sp. n. differentiates it from all nominal species of Phasmarhabditis. Phasmarhabditis quinamensis sp. n. is the second species of the genus found in Cat Tien National Park. The sympatric species P. meridionalis was also found during the present study. Phylogenetically, both species belong to different lineages within Phasmarhabditis. The molecular analysis based on partial sequences of LSU rDNA, and ITS rDNA regions showed P. kenyaensis to be the closest species to P. quinamensis sp. n.

Cat Tien National Park

The new genus Lobofemora gen. nov. is described from Vietnam to accommodate three new species: L. bachmaensis sp. nov. (Bach Ma National Park, central Vietnam), L. bidoupensis sp. nov. (Bidoup-Nui Ba National Park, central Vietnam) and L. scheirei sp. nov., the type species (Cat Tien National Park and Dong Nai Biosphere Reserve, south Vietnam). It is provisionally placed in the tribe Clitumnini Brunner von Wattenwyl, 1893. The genus is the only known Clitumnini which shows tegmina and sometimes alae in the males. Females show conspicuous foliaceous lobes on the median femora. Males and females of all species and the eggs of L. scheirei sp. nov. and L. bidoupensis sp. nov. are described and illustrated. An identification key to the species and a distribution map are provided. The definition of the tribe Clitumnini sensu Hennemann & Conle (2008) is slightly adapted to include the new genus and the tribal placement is discussed. The male of L. scheirei sp. nov. is able to stridulate by rubbing the outer margins of the tegmina against the subcostal and radial veins of the alae.

Mount Ciremai National Park has a high ecological function as a major catchment and water source areas. The objective of this research was to obtain information on floristic composition and structure in the edge forest of Seda Block, Mount Ciremai National Park. To carried out the research, the method used in the analysis vegetation was quadrat transect at an elevation of 602-614 m asl. The results showed that species composition dominated by the families of Euphorbiaceae and Moraceae, consisting of 3 stratas of heading A to C where strata A occupied by Elaeocarpus sp. (40 m) and Ficus involucrata (30 m). Ficus involucrata has the widest heading cover on the observation plot. The condition of the forest quantitative structure generally demonstrates good conditions by forming a reversed J curve, as well as a relatively moderate diversity of plant species and there are no species of plant that dominate the forest edges.

Little-known Vietnamese chydorid cladocera, Camptocercus vetnamensis Than, 1980 is redescribed on the material from Cat Tien national park, South Vietnam. Detailed morphology of limbs is described for the first time. In some features, C. vietnamensis is similar to C. uncinatus Smirnov, 1971, but can be easily differentiated from it by smaller size, morphology of postabdomen and labrum. C. vietnamensis is the only species of the genus Camptocercus strictly confined to the rheic conditions.

Holotype Male

Lyriothemis pallidistigma sp. nov. (holotype male: Cat Tien National Park, Dong Nai Prov., southern Vietnam) is described. This species is reminiscent of L. defonsekai van der Poorten, 2009 and L. elegantissima Selys, 1883, but can be separated by the shape of its secondary genitalia and its patterning. Information on its biology and ecology is provided.
