( Figs 1, 4 View FIGURES 1 – 6 , 7–24 View FIGURES 7 – 15 View FIGURES 16 – 24 )

Holotype: India: Churachandpur, Manipur, 09.ix.2011, coll. K. K. Sharma, Malvaviscus penduliflorus (Malvaceae) , 1 slide (1 adƤ) (NPC). Paratypes: Data same as holotype, 2 slides (6 adƤ) (NPC); 1 slide (4 adƤ) (IINRG-R); 1 slide (3 adƤ) (ANIC) and 1 slide (3 adƤ) (BME).

Adult female

Unmounted material ( Figs 1, 4 View FIGURES 1 – 6 ). Lac test light brown, soft, resinous. Tests occur in aggregations; live mature females crimson. Unmounted cleaned female shown in Figure 4 View FIGURES 1 – 6 .

Mounted material ( Figs 7–24 View FIGURES 7 – 15 View FIGURES 16 – 24 ). Body globular, 1.15–1.59 mm long, 0.84–1.13 mm wide at apex, 1.05–1.52 mm wide at middle and 0.65–0.95 mm wide at base (n=10).

Dorsum: Brachia sessile, clubbed in shape and slightly sclerotized, 200–270 µm long. Brachial plate circular, diameter 165–225 µm; brachial crater shallow, sub-rectangular, 115–160 µm wide, with a defined rim, dimples small, obscure, 4 in number. Anterior spiracle 170–340 µm long and 140–185 µm wide, 35–125 µm away from brachial crater. Ratio of distance of anterior spiracles from crater rim to width of brachial plate 1:0.19–0.69. Ratio of length of anterior spiracle to width of brachial plate 1:0.94–1.80. Dorsal spine well developed 155–300 µm long and 80–130 µm wide at base; pedicel small, square, slightly sclerotized, 75–120 µm long; spine 80–195 µm long and sclerotized, with 1 or 2 spinosities at its base. Ratio of length of pedicel to spine 1:0.38–0.94. Ratio of total length of dorsal spine to width of brachial plate 1:0.84–1.58. Anal tubercle abbreviated, well developed; pre-anal plate membranous, 240–480 µm long, 280–330 µm wide; supra-anal plate heavily sclerotized, hispid near apex 210–320 µm long, 250–300 µm wide, ratio of length of supra-anal plate to width of plate 1:0.84–1.14. Ratio of length of supra-anal plate to length of brachia 1:1.0–1.19. Anal fringe plates short, fringe maximum length 45.0–80.0 µm. Anal ring 6 sectored with 10 setae. Dorsal duct clusters present as a row of ducts on both sides between dorsal spine and base of anal tubercle, each cluster with 5–10 tubular ducts along with dorsal setae and spermatoid ducts.

Venter: Antennae 20–30 µm long, 3 segmented, segmentation obscure, apical segment slightly pointed with 3 long fleshy and 2 short hairy setae. Clypeolabral shield 240–290 µm long, 120–160 µm wide. Labium 2 segmented. Pre-oral lobes elongated, membranous, and present along sides of clypeolabral shield. Post-oral lobes each 140–190 µm long, membranous, dome-shaped. Legs present and vestigial, each small and one-segmented, with a rudimentary claw. Posterior spiracles each 70–80 µm long, smaller than anterior spiracles, born on a sclerotized plate, with 46–70 spiracular pores present along one side of spiracle. Marginal duct clusters distinct, 6 in number, each cluster arranged in a convoluted line consisting of 43–49 ducts without any surrounding sclerotization. Perivulvar pore clusters: 12–14 on each side of anal tubercle, circular in shape, each pore with 5–10 loculi. Ventral duct clusters irregular in shape, totalling 3 pairs: first pair anterior to mouthparts, second pair anterolateral to mouthparts, and third pair postero-lateral to posterior spiracle. Star pores: 5–19 present near mouthparts.

Comments. Kerria manipurensis is very similar to Kerria javana (Chamberlin) in having: (i) the supra-anal plate abbreviated and hispid, (ii) brachia short and indistinct, and (iii) brachial plate quadrate/rectangular with 4 or 5 indistinct dimples. However, it differs in having (character states in K. javana in brackets): (i) antennae three segmented with 3 long setae (single segmented with 4 long setae); (ii) the dorsal spine is 1.16x longer than the width of brachial plate (as long as width of brachial plate); (iii) each anterior spiracle is 1.31x longer than the width of brachial plate (length smaller or equal to width of brachial plate); and (iv) the distance of anterior spiracle from crater rim to width of brachial plate is 1.38x greater in K. manipurensis than that of K. javana .

Etymology. This species is named after its locality of collection, i.e., Manipur.
