Key to species of Paratachardina Balachowsky View in CoL View at ENA 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 View FIGURE 6 ) ...... P. morobensis View in CoL 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 View FIGURE 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 View FIGURE 4 View FIGURE 5 View FIGURE 6 View FIGURE 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) View in CoL

– 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 View FIGURE 1 N); ventral duct clusters totalling 4 pairs; each lobe of lac test smooth, with no or very faint ridges at most ( Fig. 2 View FIGURE 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 View FIGURE 1 O & P); ventral duct clusters totalling 5–7 pairs; each lobe of lac test with well-defined ridges ( Fig. 2 View FIGURE 2 D & E)....................................................................................................... 6

6. Pair of ventral duct cluster 1 (vdc-1) with 24–40 microducts combined ( Fig. 1 View FIGURE 1 O); lac test orange, or wine red to dark reddish brown with tinges of orange ( Fig. 2 View FIGURE 2 D) ..................................... P. silvestri View in CoL Mahdihassan

– Pair of ventral duct cluster 1 (vdc-1) with 49–80 microducts combined ( Fig. 1 View FIGURE 1 P); lac test purplish red to dark brown in colour, without tinges of orange ( Fig. 2 View FIGURE 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) View in CoL

– Pygidial apodemes absent. Second ventral duct cluster (vdc-2) close to third marginal duct cluster (mdciii) ...................................................................................................... P. mithila View in CoL Varshney / P. t h e a e (Green)
