( Figs 4, 5 View FIGURE 2–5 , 57–71 View FIGURES 57–59 View FIGURES 60–66 View FIGURES 67–71 )
Puparium. In life, puparium dusky white ( Fig. 4 View FIGURE 2–5 ); 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 View FIGURES 57–59 , 61, 62 View FIGURES 60–66 ). Thoracic and caudal tracheal pores indicated as C-shaped emargination ( Fig. 58 View FIGURES 57–59 , 63 View FIGURES 60–66 ); 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 View FIGURES 60–66 ) each with one pair of tubercles. Longitudinal moulting suture reaching margin ( Fig. 5 View FIGURE 2–5 ) 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 View FIGURES 60–66 ), furrow 47–48 µm long in female and 37–42 µm long in male. Geminate pores present ( Fig. 66 View FIGURES 60–66 ).
Vasiform orifice. Subcordate; posterior opening narrowed, funnel-shaped ( Figs 59 View FIGURES 57–59 , 66 View FIGURES 60–66 ); 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 View FIGURES 67–71 ). Submarginal area demarcated by a groove ( Figs 67, 68 View FIGURES 67–71 ). Thoracic ( Fig. 69 View FIGURES 67–71 ) and caudal tracheal folds indicated. Antennae reaching near base of prothoracic legs, 52–57 µm (including keel) long ( Fig. 70 View FIGURES 67–71 ). Paired ventral eighth abdominal setae present ( Fig. 71 View FIGURES 67–71 ), 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.
Material examined: Holotype, India: Andaman and Nicobar Islands, Little Andaman, Whisper waterfall trail, one puparium on slide, on Psychotria andamanica , 13.ix.2018, A.K. Dubey ( ZSI).
Paratypes. Nine puparia on nine slides, data same as of holotype ( NFIC-FRI 1 ) .
Host plant. Rubiaceae : Psychotria andamanica Kurz.
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.
