Description of adult female.

Appearance in life (Fig. 4 ). The adult female secretes powdery white wax covering over the dorsal surface of the body. Living on woody parts of the host plant, commonly attended by ants of the genus Dolichoderus Lund ( Formicidae ).

Slide-mounted adult female (values of holotype followed by range of 3 paratypes in parentheses) (Figs 5 , 6 ). Body broadly oval, sometimes almost rotund, membranous, largest specimens 2.5 (2.5–2.9) mm long and 1.7 (1.7–2.2) mm wide. Anal lobes moderately developed, each ventral surface bearing a stout apical seta 84 (80–88) μm long arising from a large circular-to-oval sclerotized area, 76 (76–80) μm wide, on ventral margin of abdominal segment VIII, occupying much of lobe. Antennae each 390 (390–410) μm in total length, with 7 antennomeres; antennal setae mostly short. Individual antennal antennomere lengths (in μm) are as follows: antennomere I – VI, each 310 (310–320); and VII (apical antennomere), 90 (90–100) long and 30 (30–40) wide. Apical antennomere with 4 fleshy setae, each 50–55 μm long, and an apical seta 34 (34–38) μm long. Clypeolabral shield 345 (345–425) μm long and 388 (388–393) μm wide. Labium unusually long and pointed, longer than clypeolabral shield, 3 segmented, 210 (210–300) μm long, with basal segment 123 (123–128) μm wide. Anterior spiracles each 138 (138–143) μm long and 70 (70–75) μm wide across atrium; posterior spiracles each 138 (138–143) μm long and 70 (70–88) μm wide across atrium. Legs well developed; hind leg segments measuring (in μm): coxa, 307 (307–313); trochanter + femur, 378 (378–400); tibia + tarsus, 238 (238–253); and claw, 55 (55–70), without a denticle. Ratio of lengths of hind tibia + tarsus to trochanter + femur 0.63: 1; ratio of lengths of tibia to tarsus 1.4 (1.2–1.4): 1; and ratio of length of trochanter + femur to greatest width of femur 3.3 (3.3–3.8): 1. Hind leg with more than 300 translucent pores on coxa only (Fig. 6 A ). Tarsal digitules setose, each 53–60 μm long; claw digitules each minutely dilated distally, about 28–38 μm long. Anterior and posterior ostioles well developed, each containing a total of 62 (60–100) trilocular pores across both lips and 7 (5–9) setae. Circulus situated between abdominal segments III and IV, 155 (150–193) μm wide and divided by an intersegmental line. Anal ring about 100 (100–120) μm wide, situated on dorsum about 1.0–1.5 times its length from apex of abdomen; with 2 rows of cells and bearing 6 setae, each 75 (75–80) μm long. Cerarii numbering not distinct, with many intermediate conical setae, tending to merge. Anal lobe cerarii each normally containing 6 or 7 conical setae of different sizes, largest about 27.5 μm long and 6.3 μm wide at base, and a small compact group of trilocular pores. Anterior cerarii similar to anal lobe cerarii but with largest conical setae slenderer, and each cerarius often subdivided into 2 or 3 smaller cerarii: additional conical setae also present, so that cerarii appear to be continuous on some parts of margin.

Dorsum. Slender, stiff setae present, mostly each about 12.5–20.0 μm long; long setae flanking anal ring fairly numerous, each 77.5–87.5 µm long, similar length to or shorter than an anal ring seta (each ring seta 75–100 µm long). Two pairs of long stout setae present just to posterior to anal ring, each about 105–113 µm long, longer and wider than an anal ring seta (Fig. 6 B ). Trilocular pores abundant. Discoidal pores fairly numerous, each slightly smaller than a trilocular pore.

Venter. Normal flagellate setae present, mostly slender and each longer than a dorsal seta, 10–35 µm long. Ventral sclerotized patches present on anal lobes only. Cisanal and obanal setae slender, each 38–40 µm long, displaced to dorsal surface between anal ring and apex of abdomen. Multilocular disc pores each 10.0–12.5 μm in diameter, present on abdominal segments, distributed as follows (numbers): segment V: 3–5, VI: 31–38, VII: 30–32, and VIII: 8–10. Trilocular pores numerous but less abundant than on dorsum. Discoidal pores same size as on dorsum, scattered. Vulva becoming heavily sclerotized at maturity, 163–175 μm long and 88–100 μm wide; with a pair of noticeable sclerotized internal pockets, base of each 70–75 μm long and 30–38 μm wide (Fig. 6 D ). Oral collar tubular ducts of 3 sizes: (i) largest ducts each 10.0–12.5 μm long and 7.5 μm wide, distributed on abdominal segments (numbers): VII: 6–8, and VIII: 2–4; (ii) slightly smaller ducts, each 7.5–10.0 μm long and about 5 μm wide, varying in number, present posterior to vulva and across medial posterior edges of abdominal segments V – VIII; and (iii) minute ducts, each 7.5–8.0 μm long and about 2.5 μm wide, few, with 5 or 6 situated medially on abdominal segments V and VI.

Etymology.

The species is named after Prof. Dr. Aunu Rauf, an Indonesian entomologist who is interested in the conservation of native insects of Indonesia.

Host plants.

An unidentified forest tree ( Meliaceae ) (Fig. 4 ).

Distribution.

Indonesia (Kalimantan, East Kalimantan Province, Sepaku).

Comments.

Paraputo raufi is most similar to P. spatholobi Williams in possessing large oral collar tubular ducts present on margins of abdominal segment VI and ventral sclerotized patches absent from margins of abdominal segments VII and VI. However, P. raufi can be readily distinguished by having (character states for P. spatholobi given in parenthesis): (i) ventral sclerotized patches present on anal lobes (absent); (ii) multilocular disc pores present on abdominal segments V – VIII (present on abdominal segments VI – VIII); and (iii) vulva with a pair noticeable sclerotized internal pocket (without a pair of noticeable sclerotized internal pocket).

Paraputo raufi also resembles P. latebrae Williams in having: (i) large oral collar tubular ducts present on abdominal segment IV only, each duct over 1.5 times as wide as a trilocular pore, in distinct groups, even if only 1 or 2 present; (ii) circulus large, divided by an intersegmental line; and (iii) setae on each side of anal ring, of similar length to or a bit shorter than an anal ring seta, and ventral submarginal setae on abdominal segments V – VIII shorter than anal ring setae. However, P. raufi can be distinguished from P. latebrae in having (character states for P. latebrae given in parentheses): (i) setae flanking anal ring noticeably longer than other dorsal setae (setae flanking anal ring short, about same length as other dorsal setae); (ii) two pairs of long stout setae present just to posterior to anal ring (absent) (iii) ventral sclerotized patches present on margins of abdominal segment VIII only (ventral sclerotized patches present on margins of abdominal segments VII and VIII); (iv) cisanal setae slender, shorter than an anal ring seta (cisanal setae stout, similar in length to an anal ring seta); (v) translucent pores present on coxa only (translucent pores present on hind coxa and tibia, sometimes also on hind femur); and (vi) large oral collar tubular ducts absent from head (sometimes present on head).

It is also similar to P. acehicus Williams in having: (i) setae flanking the anal ring noticeably longer than other dorsal setae; (ii) two pairs of long stout setae present just to posterior to anal ring, all longer and wider than anal ring setae; (iii) cisanal setae slender, shorter than anal ring setae; (iv) translucent pores present on coxa only; and (v) large oral collar tubular ducts absent from head. However, P. raufi can be distinguished from P. acehicus in having (character states for P. acehicus given in parentheses): (i) large oral collar tubular ducts present (absent); (ii) ventral sclerotized patches present on margins of abdominal segment VIII (absent); and (iii) vulva with a pair of noticeable sclerotized internal pockets present (absent).
