- <p><b><i>Brevitobrilus larae</i> sp. nov.</b></p><p>(Figs 5– 9)</p><p><i>Holotype.</i> Female, <b>Vietnam</b>, <i>Kon Tum Prov</i>., Kon Plong Distr., Kon Chu Rang Nature Reserve, pond in forest, 1077 m a.s.l., 14°35′22″N, 108°25′04″E, 10 Oct. 2018, coll. L. Iogansen. Microscope slide No. A-9195, ZISP.</p><p><i>Paratypes</i>. 6 females, same data as for holotype.</p><p><i>Description.</i> Females. Morphometric descriptions of the holotype and paratypes are given in Table 2. Cuticle thin, in total about 2 µm thick in middle of body. Outline of head round and not offset. Head with six distinct lips, each with one small papilla. Longer cephalic setae 6–8 µm, shorter setae about 4 µm. Width of head 19 µm. Buccal cavity 8–10 (9) µm wide and 10 µm long; total depth of stoma (buccal cavity and pockets) 20–26 (23) µm; two pockets separated by short isthmus, each pocket with one teeth, distance between tops of teeth 9 µm. Amphid openings at level of bottom of buccal cavity or at level of first pocket; amphid diameter 4 µm, approximately one-sixth part of corresponding body width. Reproductive system didelphic, amphidelphic; ovaries reflexed, oocytes arranged in double rows in germinal zone; only two females with mature eggs in uterus. Depth of vagina corresponding to one-third – half of body width. Tail elongate-conoid, spinneret 1–2 µm long; subterminal setae absent.</p><p>Male not found.</p><p><i>Comparision.</i> The new species <i>Brevitobrilus larae</i> <b>sp. nov.</b> most closely resembles <i>B. orientalis</i> Tsalolikhin, 2013, which was described from Kazakhstan (Tsalolikhin, 2013). The new species differs from <i>B. orientalis</i> by longer body (851−1048 µm <i>vs</i> 788−871 µm), longer (6−8 µm <i>vs</i> 5−6 µm) and thinner, not hornlike cephalic setae, in longer tail (111−147 µm <i>vs</i> 77−82 µm) and absence of subterminal setae.</p><p><i>Note</i>: All absolute measurements are in µm and the form: range and mean ± error of mean.</p><p><i>Note</i>: All absolute measurements are in µm and in the form: range and mean ± error of mean.</p><p><i>Etimology</i>. The species is named after the herpetologist Larissa (Lara) Iogansen, who collected material for me in the jungles of Vietnam.</p>
