Minutaleyrodes whisper
sp. nov.
(
Figs 4, 5
,
57–71
)
Puparium.
In life, puparium dusky white (
Fig. 4
); suboval; female
590–600 µm
long,
510–530 µm
wide; male
480– 520 µm
long,
420–430 µm
wide; broadest from metathorax to abdominal segment II region; constricted at thoracic tracheal pore and abdominal segment VI region; found singly on lower surface of leaves; 1 or 2 puparia per leaf.
Margin.
Irregularly crenulate; narrow marginal/submarginal area with 2 or 3 rows of polygonal grooves (
Figs 57
,
61, 62
). Thoracic and caudal tracheal pores indicated as C-shaped emargination (
Fig. 58
,
63
); thoracic tracheal pore sometimes overlapped with reticulated submarginal polygonal grooves and obsolete. Anterior and posterior marginal setae
12–25 µm
and
17–27 µm
long, respectively.
Dorsum.
Submargin not differentiated from the dorsal disc; submarginal papillae visible only on the anterior and posterior margins. Prothorax, metathorax and abdominal segment I (
Figs 60, 64
) each with one pair of tubercles. Longitudinal moulting suture reaching margin (
Fig. 5
) and transverse moulting suture turning anteriorly and reaching near thoracic tracheal pore opening. Cephalothorax length greater than abdomen length; in female
295–320 µm
and
280–295 µm
long, respectively, in male
237–270 µm
and
240–243 µm
long, respectively. Mesothorax
35 µm
long, metathorax
25 µm
long. Abdominal segments I–VIII (A1–A8, n= 6): A1: 27–37, A2: 25–30, A3: 25–30, A4: 20–25, A5: 20–25, A6: 20–23, A7: 12–17, A8:
32–40 µm
long, respectively. Thoracic tracheal furrows absent. Caudal tracheal furrow narrow, deep, without any striations (
Fig. 65
), furrow
47–48 µm
long in female and
37–42 µm
long in male. Geminate pores present (
Fig. 66
).
Vasiform orifice.
Subcordate; posterior opening narrowed, funnel-shaped (
Figs 59
,
66
);
35–40 µm
long,
30–33 µm
wide in female;
32 µm
long,
25–27 µm
wide in male; operculum subcordate, filling the orifice and obscuring the lingula.
Venter.
Imprints of leaf epidermis prominent (
Fig. 67
). Submarginal area demarcated by a groove (
Figs 67, 68
). Thoracic (
Fig. 69
) and caudal tracheal folds indicated. Antennae reaching near base of prothoracic legs,
52–57 µm
(including keel) long (
Fig. 70
). Paired ventral eighth abdominal setae present (
Fig. 71
),
5 µm
long,
25 µm
apart. Adhesive sacs and spiracles present.
Chaetotaxy.
Cephalic setae
12–15 µm
long, eighth abdominal setae
3–5 µm
long,
40 µm
apart and caudal setae
15–20 µm
long,
22–27 µm
apart. First abdominal setae absent.

Paratypes
.
Nine puparia on nine slides, data same as of

Distribution.
India
:
Andaman and Nicobar Islands
, Little Andaman.
Etymology.
The species is named after the Whisper waterfall located in the Little Andaman from where the species was collected along the hiking trail.
Remarks:
Puparia of the new species resemble those of
M
.
minuta
(Singh)
, but differ from them in shape, presence of reticulated dorsal submargin, narrow and straight caudal furrow, and absence of submedian tubercles on abdominal segments; and from
M
.
suishanus
Takahashi
in having the reticulated submargin and the longitudinal moulting suture reaching margin.
