Description
Summary:Family Aporcelaimidae Heyns, 1965 71. Aporcelaimidae gen. spp.— {25, 55, 57, 59, 64, 65, 69} (0, 4, 23, 27; 10) Population structure and abundance. 1–5 juvenile specimens and females in each sample (up to 2 x10 3 /m2). Remarks. The taxon unites approximately three to four representatives of the family that owing to various reasons were not identified to the rank of genus or further. 72. * Aporcelinus cf. granuliferus (Cobb, 1893) Andrássy, 2009 — {55, 63, 68, 70} (0, 0, 8, 27; 6) Population structure and abundance. At site 55—21 juvenile specimens, nine females and one male (11 x10 3 /m2), at the other sites—1 to 4 juvenile specimens and females (up to 1 x10 3 /m2). Ecology and distribution. Likely an amphibiont. Dwells predominantly in wet mosses and soil but also occurs in water bodies. Considered a widespread species. Reported from all continents except for Australia and Antarctica (Andrássy 2009a). However, there are doubts concerning conspecificity of populations from different geographic regions (see Remarks). Not previously reported from Vietnam. Remarks. In 2009, Andrássy proposed for Aporcelaimidae the new genus Aporcelinus, in which he included new species and species of other genera that had been previously attributed both to this family and to Qudsianematidae (Andrássy 2009a). Aporcelinus granuliferus belongs to the latter group of species and was previously assigned to the qudsianematid genus Allodorylaimus Andrássy, 1986 (Andrássy 2009a, b). Further studies on some representatives of Aporcelinus revealed that some details of their morphology are in fact closer to the characteristics of Qudsianematidae, but molecular analysis is needed to finally solve the problem of attribution (Vinciguerra et al. 2014; Nguyen et al. 2016a). The species Aporcelinus granuliferus itself is problematic, with a complicated taxonomic history. Some populations earlier believed to represent this species most likely belong to different species (Andrássy 2009a; Peña-Santiago & Abolafia 2016). The Vietnamese females and ...
