D5B1B2B4F58F5E5F8A5140154175ADD4.taxon	description	Description. Body (Fig. 1). Total length of holotype 1.25 mm; allotype 1.5 mm; male length, 1.1 - 1.6 mm; female length, 1.0 - 1.8 mm. Body elongated, segments slightly widen towards posterior margin; head about as long as broad. Pleotelson with one plumose ventro-lateral seta on each side. All drawings are of the (male) holotype except for the female ThVIII and second article of the antennule, which were drawn from the female allotype. Antennule (Fig. 2 A). Seven-segmented; first three articles slightly longer than the other four; first two articles similar in length and the third is the longest; sexual dimorphism manifested by the presence of a well-developed antennal organ on the inner distal margin of the second article in males (Fig. 2 A), organ represented as a protrusion with a smooth, moderately long seta in its middle lateral area. On the female antennule, only a short seta is present in the homologous position as the male antennal organ (Fig. 2 C); inner flagellum almost square; fourth article slightly longer than the fifth, with two aesthetascs, which is the smallest of all the articles at half the length of the seventh, which is slightly longer than the penultimate articles; sixth and seventh articles each with three aesthetascs, which are placed sub-terminally on the last article; setation pattern as shown in Fig. 2 A. Antenna (Fig. 2 B). Seven-segmented; approximately 70 % the length of AI; first three articles small, all similar in size to the fifth and about 50 % the length of the fourth article, which is similar in size to the last two articles; distal article with four setae, one of which is plumose. Setal formula: 0 / 0 / 1 + 0 / 1 + 1 / 0 + 2 / 4 (1). Labrum (Fig. 2 D). Almost flat with eight main teeth, with the two central teeth that are slightly different from the others, more rounded, plus two lateral teeth on each side. Ventral surface ornamented with rows of fine spinules. Mandible (Fig. 2 E). Pars incisiva with four teeth and a well-developed triangular tooth on the ventral edge; pars molaris with five claws, one strongly modified distal claw that is slightly separated from the rest, with small denticles, and four claws (the two proximal ones are joint) with fine long setules; mandibular palp one-segmented, with a distal seta that does not exceed the length of the pars incisiva. Maxillule (Fig. 2 F). Proximal endite with four long serrulate claws; distal endite with seven claws, the basal one very thin, the two distal ones smooth and the other five with denticles, and with three sub-terminal smooth setae on the outer distal margin. Maxilla (Fig. 2 G). Four-segmented, first two articles with an elongated endite, with two and four setae, respectively, one setae on each endite plumose; third article rectangular with one strong claw and eight smooth setae; fourth article reduced with five setae. Setal formula: 2, 3 + 1, 9, 5. Thoracopods I-VII (Fig. 3 A-G). Well developed, gradually increasing in length from ThI to ThV, last two thoracopods similar in length; ThI without epipod, ThII-VII with large epipod, each about the same length as the corresponding basipod; basipod of ThI-VII with one smooth seta on inner distal corner. Exopod of ThI one-segmented, two-segmented in ThII-VII; exopod longer than first two endopod articles in ThII-VI and equal in length in ThVII; two barbed setae on each exopodal article and with one group of strong ctenidia at the base of the inner setae. Endopod four-segmented; first article short, second and third long and similar in length, both with a cluster of strong spinules along the outer margin; fourth article reduced, with two smooth, strong claws of similar length and one seta; pair of smooth inner setae on first article present only on ThI; inner setae on article two always barbed; outer small seta on third article of ThI-VII smooth; outer distal setae on second article of all Ths plumose. Setal formula of endopod as follows: Thoracopod I 2 + 0 / 2 + 1 / 1 + 1 / 3 (1) Thoracopod II 1 + 0 / 2 + 1 / 1 + 1 / 3 (1) Thoracopod III and IV 0 + 0 / 2 + 1 / 1 + 1 / 3 (1) Thoracopod V to VII 0 + 0 / 1 + 1 / 1 + 1 / 3 (1) Thoracopod VIII (Fig. 4 A, B). Almost square; basal region of the penial complex with three lobes: inner lobe (I. Lb.), outer lobe (O. Lb.) and dentate lobe (D. Lb.); rectangular inner lobe completely integrated into basal region, a little shorter than dentate lobe; trapezoidal outer lobe as dentate lobe; endopod (Endp.) integrated on basipod, with one long smooth seta; reduced exopod, with two spinules; basipod very large, square, slightly recurved caudally, with a distal row of small denticles, with two lobes on the frontal side, one of which is recurved inwards (crest-like protuberance), without setae. The ThVIII of the type species, S. laorsriae, is shown for comparison (Fig. 4 C). Thoracopod VIII female (Fig. 4 D). One-segmented with two long smooth setae and two small denticles at the base. First pleopods. Absent. Uropod (Fig. 4 E). Sympod five times as long as wide and twice as long as endopod, with nine barbed spines about equal in length except the distal-most, which is twice as long as the others, occupying the distal half; exopod 30 % longer than endopod, with four barbed setae, two terminally and unequal in length; distal outer corner of endopod forming a spinose process, with two row of setules and one strong spine that is 20 % longer than the endopod, with setules, one plumose seta near the base and two small barbed terminal setae of different lengths. Pleotelson (Fig. 4 F). With one small, plumose ventro-lateral seta on each side close to the insertion of the furca. Anal operculum slightly concave. Furca (Fig. 4 F). Rectangular, with three barbed spines, outer two spines twice as long as the innermost one; two equally long dorsal plumose setae; lateral furcal organ " cork " - like.	en	Camacho, Ana I., Leclerc, Philippe (2022): A new species of the genus Siambathynella Camacho, Watiroyram & Brancelj, 2011 (Crustacea, Bathynellacea, Parabathynellidae) from a Thai cave.

She was head of the Groundwater Hydrobiology and Ecology Laboratory (UMR CNRS 5023, Laboratoire d'Ecologie des Hydrosystemes Fluviaux, Hydrobiologie et Ecologie Souterraines) at Universite Claude Bernard Lyon 1 in France. She worked in various international programs on subterranean biodiversity and groundwater ecology from the perspective of environmental sustainability, particularly in the project " Protocols for the ASsessment and Conservation of Aquatic Life In the Subsurface (PASCALIS) ". She was also a member of the biospeleological team that led Expedition Thai-Maros in 1985 and was highly active in the sampling of the caves, especially Tham Chiang Dao.	en	Camacho, Ana I., Leclerc, Philippe (2022): A new species of the genus Siambathynella Camacho, Watiroyram & Brancelj, 2011 (Crustacea, Bathynellacea, Parabathynellidae) from a Thai cave.
