(Figure 9)– Figure 12 (d))
Puparium (n = 10, 5 female, 5 male)
Broadly elongate oval (Figure 9)); female usually symmetrical; male generally asymmetrical; median and submedian area transversely pigmented on prothorax to metathorax and from abdominal segment III–VI and median anterior and posterior area (Figure 10)); sexually dimorphic, female puparia larger than male puparia, female 1960–2050 µm long, 1150–1400 µm wide; male 1560–1690 µm long, 840–1120 µm wide. Anterior marginal setae absent. Posterior marginal setae 30 µm long, 320– 367 µm apart.
Margin
Finely crenulate (Figure 10)); each crenulation accompanied by a submarginal papilla at base, 10–11 crenulations in 0.1 mm.
Dorsum
Granular, faintly tuberculate. Median length of cephalothorax 830–880 µm in female, 700–760 µm in male, abdomen 1130–1170 µm long in female, 860–940 µm long in male. Longitudinal moulting suture reaching margin and transverse moulting sutures reaching submargin. Pro-mesothoracic suture reaching subdorsal area, thereafter cuticle becomes unpigmented towards margin. A pair of lateral longitudinal furrows extend from cephalus to abdominal segment VII on submedian area. Eye spots present on lateral longitudinal furrows (Figure 10,g)). Four pairs of tuberculate arms, little wider than segment sutures, extending from lateral longitudinal furrows to submargin, 1 pair each in extension of abdominal segment sutures from III/IV to VI/VII. Submedian depressions present, faint. The median length of the cephalothorax was greater than that of the abdomen in both male and female puparia. The median length of the mesothorax and metathorax was 130–152 µm and 82–100 µm, respectively, in the female, and 110–130 µm and 80–100 µm, respectively, in the male. The median length of the mesothorax was greater than that of the metathorax. Median length of abdominal segments I–VIII in the female: I 95–100, II 100–102, III 107–112, IV 115–120, V 110–112, VI 100–105, VII 50–67, VIII 62–80 µm long; and in the male: I 75–85, II 75–85, III 82–95, IV 82–95, V 85–90, VI 70–82, VII 25–37, VIII 62– 75 µm (including pockets 15–20 µm long) long. The median length of abdominal segment IV is the greatest, segments III and V subequal, segment VII the smallest, segment VIII longer than VI, segment VI smaller than segments III and V and subequal to segments I and II. Median lengths of abdominal segments I–VIII: IV> III = V> VIII> VI = II = I> VII. Median area of abdominal segments II–V unpigmented in transversely oval shape (Figure 9), Figure 10 (c)). Distance from posterior end of vasiform orifice and caudal tracheal pore opening area 325–360 µm in female, 262–295 µm in male. Abdominal segment sutures usually reaching subdorsal area; intersegmental sutures of abdominal segments II/III to VII/VIII extending to submargin-margin. Thoracic and caudal tracheal furrows absent. Geminate pores scattered over dorsal surface, a row on submargin, 48–50 pairs. Submarginal and subdorsal setae present. Pockets discontinuous.
Vasiform orifice
Subcordate (Figure 10 (e,f)), 60–70 µm long, 62–65 µm wide in female; as long as wide in male, 57–62 µm long and wide; operculum subrectangular, covering nearly half the length of the orifice, 32–35 µm long, 52–55 µm wide in female, 30–47 µm long, 42– 47 µm wide in male. Lingula exposed, not reaching beyond posterior margin of the vasiform orifice, 15–32 µm long in female, 12–20 µm long in male. A pair of setae present subapically near tip of lingula, 7 µm long.
Venter
With wax glands or impression of tubercles. A pair of ventral eighth abdominal setae present, 20–30 µm long, 60–70 µm apart in female, 15–22 µm long, 40–60 µm apart in male. Antennae 145–150 µm long in female, 130–137 µm long (including keel 2 µm long) in male, extending to outside of prothoracic legs (Figure 9)). Spiracles present, first pair of spiracles located posterior of pro-mesothoracic suture and outside the lateral longitudinal furrows, second pair anterior of meso-metathoracic suture, third pair lateral of abdominal segment suture II/III and the eighth abdominal spiracle posterior lateral of vasiform orifice (Figure 10)). Apical pads present.
Chaetotaxy
Anterior marginal setae absent. Posterior marginal setae 30–32 µm long, 320–367 µm apart in female; 27 µm long, 295–327 µm apart in male. Six pairs of subdorsal setae, 2 pairs each anterior and posterior area and 1 pair each on meso- and metathorax. Cephalic, first and eighth abdominal, submarginal and subdorsal setae 15–17 µm long.
Adult male (n = 1)

Wings bluish green in life. Upper and lower lobes of compound eyes not connected (Figure 11)). Antennae 7-segmented, segment V smallest, segment VI longest, segment IV longer than V but smaller than VII. Antennal segments III–VII observed as: VI> III> VII> IV> V.

Host plant
Papillionaceae: Dalbergia candenatensis (Dennst) Prain (= Dalbergia torta A. Gray).
Material examined
Holotype ‘puparium’; West Malaysia, Pahanng Province, Tiomen Island, Kampung Tekek, 6 puparia (2 female, 4 male on slide 1) under one coverslip, 16 March 1984, J.H. Martin (NHM 4268). The female puparium, the farthest to the right of the three in the third row,is selected as the holotype.
Paratypes
Data same as for the holotype. Thirty-five puparia on four slides (4 males on slide 2; 6 male puparia on slide 3; 8 puparia (2 female, 6 male) on slide 4), 16 March 1984, J. H. Martin (NHM 4268); 5 puparia (4 male, 1 female) under one cover slip, three adults (2 females, 1 male) under one cover slip, on Dalbergia torta, new growth, one female puparium, 4 male puparia, 17 February 1985, J.H. Martin (NHM 4504) and 5 (1 female, 4 male) with the holotype (4268).
Distribution
Malaysia.
Etymology
This species is named in honour of Jon H. Martin, a whitefly taxonomist at the Natural History Museum, London, for his valuable contributions to this group of insects.
Remarks
Puparia of this species are similar to those of A. sulawesiensis Dubey sp. nov. in shape but differ in the pattern of pigmentation, more pronounced cephalothoracic furrows, the eye spots, and the number of dorsal setae.
