Description of adult female.

Appearance in life. Adult females produce a powdery white wax covering the dorsal surface of the body. Living on woody parts of its host plant (Fig. 1 ), commonly attended by ants of the genus Dolichoderus Lund ( Formicidae ) (not visible in Fig. 1 ).

Slide-mounted adult female (values of holotype followed by range of 3 paratypes in parentheses) (Figs 2 , 3 ). Body broadly oval, sometimes almost rotund, membranous, largest specimens 2.13 (2.13–2.25) mm long and 1.62 (1.62–1.73) mm wide. Anal lobes weakly developed, each ventral surface bearing a stout apical seta 80 (80–88) μm long arising from a large circular-to-oval sclerotized area, about 57–79 μm wide, on ventral margin of abdominal segment VIII; small sclerotized areas present also on ventral margins of segments VII and VI. Antennae each 340 (340–360) μm in total length, with 7 antennomeres; antennal setae mostly short. Individual antennal antennomere lengths (in μm) are as follows: antennomere I – VI, each 260 (260–270); and VII (apical antennomere), 80 (80–90) long and 40 (40–45) wide. Apical antennomere with 4 fleshy setae, each 30–38 μm long, and an apical seta 36 (36–90) μm long. Clypeolabral shield 258 (258–263) μm long and 245 (245–250) μm wide. Labium unusually long and pointed, longer than clypeolabral shield, 3 segmented, 280 (280–300) μm long, with a basal segment 150 (150–155) μm wide. Anterior spiracles each 110 (110–113) μm long and 58 (58–60) μm wide across the atrium, while the posterior spiracles are 110 (110–113) μm long and 65 (50–65) μm wide across the atrium. Legs well developed (Fig. 3 A ); hind leg segments measuring (in μm): coxa, 213 (213–215); 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 0.69 (0.69–0.7): 1; ratio of lengths of the tibia to tarsus 1.5 (1.2–1.5): 1; and ratio of length of trochanter + femur to the greatest width of femur 3.1 (3.1–3.2): 1. Hind legs with only about 10–20 translucent pores, by anterior margin of coxa only (Fig. 3 B ). Tarsal digitules setose, each 48–50 μm long, claw digitules also setose, each about 28–30 μm long. Anterior and posterior ostioles well developed, each containing a total of 62 (60–70) trilocular pores across both lips and 14 (14–25) setae. Circulus situated between abdominal segments III and IV, 140 (140–150) μm wide and divided by an intersegmental line. Anal ring about 108 (100–108) μm wide, situated on dorsum at about 1.0–1.5 times its length from apex of abdomen; with 2 rows of cells and bearing 6 setae, each 78–83 μm long. Cerarii numbering not distinct, with many intermediate conical setae, merged to form a marginal band of trilocular pores and enlarged conical setae. Anal lobe cerarii each normally containing 6 or 7 conical setae of different sizes, largest about 25 μm long and 7.5 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 form a continuous band around margin.

Dorsum with slender, stiff setae, each about 20–25 µm long, present around margins and across abdominal segments (Fig. 3 C ). Setae flanking anal ring longer than other dorsal setae, longest 78–88 µm long but mostly each 45–50 µm long, each seta shorter than or same length as an anal ring seta (each ring seta about 75–88 µm long). Apparent cisanal and obanal setae stout, each 100–113 µm long, displaced onto dorsum, situated immediately posterior to anal ring. Multilocular disc pores absent. Trilocular pores abundant, evenly distributed. Discoidal pores fairly numerous, each only slightly smaller than a trilocular pore.

Venter with normal flagellate setae present, mostly slender and each longer than a dorsal seta, each 33–58 µm long. Ventral sclerotized patches present on anal lobes and on margins of abdominal segments VI and VII (Fig. 3 D ). Multilocular disc pores, each 7.5–8.8 μm in diameter, few, numbering only 6–10 by posterior medial edge of abdominal segment VII only (Fig. 3 E ). Trilocular pores numerous but less abundant than on dorsum. Discoidal pores same size as on dorsum, scattered. Vulva becoming heavily sclerotized at maturity, 100–113 μm long and 88–100 μm wide. Trilocular pores same as those on dorsum, each 2.5–3.8 μm wide, scattered throughout. Oral collar tubular ducts of 2 sizes: larger ducts each 10–13 μm long and 3.8 μm wide, few, with 2 or 4 situated marginally on abdominal segments VII and VIII; smaller ducts each 7–8 μm long and 2.5 μm wide, intermingled with a few large ducts, forming a submarginal-to-marginal cluster of 10–14 ducts on each marginal area between segments VII and VIII, a few also present in medial area of abdominal segment VI.

Etymology.

The species is named after Prof. Dr. Edhi Martono, an Indonesian entomologist who has dedicated his work to Integrated Pest Management (IPM) and the toxicology of insecticides.

Host plants.

Unidentified forest tree ( Rubiaceae ) (Fig. 1 ).

Distribution.

Indonesia (Kalimantan, East Kalimantan Province, Sepaku).

Comments.

Paraputo martonoi is most similar to P. carnosae (Takahashi) in having: (i) large oral collar tubular ducts on abdomen only, each over 1.5 times as wide as a trilocular pore; (ii) a large circulus divided by an intersegmental line; (iii) setae on each side of anal ring, of similar length or a bit shorter than an anal ring seta, and ventral submarginal setae on abdominal segments V – VIII shorter than an anal ring seta; and (iv) ventral sclerotized patches present on anal lobes, also on ventral margins of abdominal segment VII, and sometimes VI. However, P. martonoi can be readily distinguished from P. carnosae by having (character state for P. carnosae given in parentheses): (i) dorsal surface with slender, stiff setae, each about 20–25 µm long (with minute setae, stiff and pointed, mostly each about 7.5 µm long); (ii) legs stout (slender); (iii) translucent pores present on hind coxa only (translucent pores present on hind coxa and tibia); (iv) oral collar tubular ducts present on abdominal segments VII and VIII (present on segments V – VIII); and (v) multilocular disc pores present by posterior medial edge of abdominal segment VII only (present by posterior medial edges of segments VI – IX).

Paraputo martonoi also resembles P. latebrae Williams in possessing large oral collar tubular ducts present between anal lobes. However, P. martonoi can be readily distinguished by having (character states for P. latebrae given in parenthesis): (i) large oral collar tubular ducts absent on head (present on head, usually between antennal bases); (ii) ventral sclerotized patches present on margins of abdominal segments VI and VII (present only on margins of abdominal segment VII); (iii) cisanal setae slender, much shorter than anal ring setae, each 20–30 µm long (cisanal setae stout, similar to anal ring setae and about same length, each 70–75 µm long); and (iv) multilocular disc pores present on medial edge of abdominal segment VII only (present across medial areas of abdominal segments VI and VII and sometimes represented on segment V and vulva).
