description: Key to species of Paratachardina Balachowsky based on adult females
1. Each brachial plate with about 200 pseudospines, occupying most of plate. Legs vestigial, each composed of a membranous tubercle-like area with a sclerotized claw (Fig. 6) ...... P. morobensis Williams & Watson
– Each brachial plate with fewer than 100 pseudospines, not occupying most of plate. Legs usually absent, if present vestigial, represented by a sclerotized claw or small sclerotized plate, not attached to a membranous tubercle-like area................................................................................................................................. 2
2. Antennae 4 segmented, each segment moderately sclerotized (Fig. 3); brachial plates each equilateral triangular; outer row of microducts of each marginal duct cluster composed of medium-sized microducts only ............................................................................................................................. P. decorella (Maskell)
– Antennae 2 or 3 segmented, each segment entirely membranous and delineated by a small sclerotized area (vignettes Figs 4–7, 10–12); brachial plates variable, usually subcircular, oblong, or subquadrate; outer row of microducts of each marginal duct cluster either all composed of large-sized microducts or a combination of 2 size classes (lsm + msm), usually with at least some large-sized microducts........................... 3
3. Brachial plates each with 9–15 pseudospines; each brachial plate less than 60 µm (47–58 µm) long ......... ...................................................................................................................................... P. minuta (Morrison)
– Brachial plates each with 20–60 pseudospines; each brachial plate more than 60 µm (usually 70–120 µm) long .............................................................................................................................................................. 4
4. Body with 4 distinct lobes, even if anterior lobes smaller, with a clear indentation or constriction anteriorly on head. With a ventral duct cluster (vdc-2) close to mouthparts on each side........................................... 5
– Body trilobate to broadly pear-shaped, with a round contour on head. Without a ventral duct cluster close to mouthparts on each side (i.e., vdc-2 closer to mdc-ii or mdc-iii)............................................................ 7
5. Pair of ventral duct cluster 1 (vdc-1) divided into 2 distinct clusters, distance between these 2 clusters equal to or greater than width of tentorial bridge (Fig. 1 N); ventral duct clusters totalling 4 pairs; each lobe of lac test smooth, with no or very faint ridges at most (Fig. 2 B) ................. P. pseudolobata sp. nov.
– Pair of ventral duct cluster 1 (vdc-1) merging or almost touching, distance between these 2 clusters less than width of tentorial bridge (Fig. 1 O & P); ventral duct clusters totalling 5–7 pairs; each lobe of lac test with well-defined ridges (Fig. 2 D & E)....................................................................................................... 6
6. Pair of ventral duct cluster 1 (vdc-1) with 24–40 microducts combined (Fig. 1 O); lac test orange, or wine red to dark reddish brown with tinges of orange (Fig. 2 D) ..................................... P. silvestri Mahdihassan
– Pair of ventral duct cluster 1 (vdc-1) with 49–80 microducts combined (Fig. 1 P); lac test purplish red to dark brown in colour, without tinges of orange (Fig. 2 E) ..................................... P. mahdihassani sp. nov.
7. Pygidial apodemes well-developed. Second ventral duct cluster (vdc-2) close to second marginal duct cluster (mdc-ii). ........................................................................................................ P. ternata (Chamberlin)
– Pygidial apodemes absent. Second ventral duct cluster (vdc-2) close to third marginal duct cluster (mdciii) ...................................................................................................... P. mithila Varshney / P. t h e a e (Green)
