Spiracles subequal in size, each peritreme 42–60 Μm long, 31–50 Μm wide, each sclerosis about 50 µm long. Quinquelocular pores each 5 Μm diameter: with 8–11 between mesothoracic spiracles and submarginal band of tubular ducts, and 10–13 in a broad band medially between metathoracic spiracles, plus 2–4 laterad to each metathoracic spiracle; also in a single, complete submarginal band of about 50–70 pores, band one pore wide. Bilocular pores each about 3 Μm wide, with 103–135 per side, dispersed within submarginal tubular duct band. Multilocular pores, each 7–8 Μm diameter with 9–10 loculi: in groups of 3 or 4 between each metathoracic and mesothoracic spiracles; in transverse bands across abdominal segments as follows; segment II with 12–24, III with 14–28, IV with 15–35, V with 18–25, VI with 12–19, VII with 2–3 on each side of vulva.

Anal ring ventral, diameter 27–35 Μm, composed of 2 semi–circles, each half with 10–12 pores and 3 spinose setae each 65–75 µm long.
Comments. Bodenheimer’s (1941) original description of N. balachowskii is incomplete, lacking such details as presence of: (i) dorsal microtubular ducts; (ii) 8–11 quinquelocular pores between mesothoracic spiracles and submarginal band of tubular ducts, and 10–13 quinquelocular pores between metathoracic spiracles; (iii) bilocular pores interspersed between tubular ducts on venter; (iv) microspines on abdominal segments on venter; and (v) presence of eyes.
The adult female of N. balachowskii shares with N. japonica and the type species, N. pulvinata , the following characters: (i) one-segmented antennae; (ii) legs absent; (iii) seta-pore clusters absent; (iv) anal ring ventral; and (v) anal ring setose, with pores. Nidularia balachowskii can be easily separated from N. pulvinata by the presence of quinquelocular pores lateral to each anterior spiracle and medial to each posterior one in N. balachowskii but lying within each peritreme in N. pulvinata ). Nidularia balachowskii differs from N. japonica in the absence of tubular ducts dorsally (present on thorax and abdominal segments on venter of N. japonica ). The adult female of N. balachowskii differs from K. greeni , K. nahalali and K. spatulatus (characters of the latter in brackets): (i) onesegmented antennae (six-segmented antennae); (ii) legs absent (legs fully-developed); (iii) seta-pore clusters on venter absent (present); (iv) tubular ducts on both venter and dorsum of Type 2 (Type 1 and Type 2); (v) anal ring ventral (dorsal); and (vi) anal ring setose, with pores (absent).
However, along with N. balachowskii , two Israeli species, K. echinatus and K. hermonensis , and two Palaearctic species, K. quercus ( Podsiadlo, 2012) and K. vermilio ( Pellizzari et al., 2012) , share the following traits: (i) one-segmented antennae or with indistinct segmentation; (ii) seta-pore clusters absent; (iii) legs absent or reduced to three-segments; (iv) only Type 2 tubular ducts present on venter; (v) anal ring ventral; and (vi) anal ring setose and with pores.
Third-instar female ( Fig. 42; Plate 6 View PLATE 6 , fig. b). General appearance. Body oval, soft and flat, 0.5–0.8 mm long, 0.4–0.5 mm wide; dorsum brownish and venter yellowish-white; dorsal surface covered with 5 longitudinal rows of rectangular wax plates, median row with 11 plates, mediolateral rows with 9–11 plates and marginal rows with 7–9 plates. Wax plates largest medially.
Mounted specimen. Body oval; 0.7–0.8 mm long, 0.4–0.5 mm wide.
Margin. Marginal setae spinose, each 10 µm long, 5 µm wide at base, in a complete single line of 21–30 on each side.
Dorsum. Setae and tubular ducts absent. Microtubular ducts with a circular opening about 2 Μm diameter, inner ductule about 1 Μm long and outer ductule 0.5 Μm long; in 4 longitudinal rows, each with 9 pores.
Venter. Eyes circular, each 5 µm diameter, lateral to each scape. Antennae 1 segmented, 25–30 µm long; with 2 fleshy setae on apical tip. Legs reduced to stumps that appear to be 1 segmented, each 15–20 µm long; occasionally with a round sclerotized area on apex. Tentorium 120–125 µm long, 87–95 µm wide. Labium 3 segmented, triangular, 62–80 µm long, 45–50 µm wide; labial setae setose: basal segment with 1 pair about 5 µm long, median segment with 1 pair 17–20 µm long and with 3 pairs of apical setae, each 8–13 µm long. Spiracles subequal in size, each peritreme 13 Μm long, 8 Μm wide; crescent-shaped sclerosis 28–35 µm long; each spiracle with quinquelocular pores anterolaterally, each 3 µm diameter, each anterior spiracle with 2 pores and each posterior spiracle with 1 pore. Tubular ducts of Type 2 only, with inner ductule 5–8 µm long, inner cup about 5 µm wide and outer ductule 8–13 µm long, arranged in a complete submarginal band 2–3 ducts wide; ducts also scattered medially on head and thorax. Ventral setae of two types: (i) setose setae: with 3 pairs anterior to tentorium, each 8 µm long; abdominal segments II–VII with medial and submedial setae, each 10 µm. Also with a pair just anterior to anal ring, about 7 µm long, plus a pair posterior to anal ring 12 µm long; (ii) tack-like setae, each 3 µm long, with 2 medial to each coxa, and also submarginally in abdominal segments II–VII. Microspines, each 2 µm long, in groups of 1–8 over entire body but in 2–5 transverse rows on abdominal segments. Anal ring ventral, diameter 25 µm, circular with a posterior gap, each half with 3 spinose setae, each 25 µm long, and 5–8 pores. Anal lobes barely developed, each with 2 spinose setae on apex, one 10 µm long and other 12 µm long, each similar in shape to marginal setae, plus a long setose apical setae 48–50 µm long.
Comments. The third-instar female of N. balachowskii can be distinguished from those of Kermes species by its narrow submarginal band of ventral tubular ducts (only one to two ducts wide). All other third-instar nymphs of Kermes species that have been described have a wider submarginal band, five to ten ducts wide. Nidularia balachowskii also resembles K. echinatus , K. hermonensis and K. vermilio in having (characters of K. greeni , K. nahalali and K. spatulatus in brackets): (i) leg segmentation reduced (legs fully developed); (ii) anal ring ventral (dorsal); (iii) tubular ducts of Type 2 on venter (Types 1 and Type 2 on venter); and (iv) sclerotized anal lobes absent (present).

Antennae segmentation indistinct, appears to be 3-segmented, each about 55 µm long; with 1 short seta on basal segment and a setose seta and 2 fleshy setae on apex. Legs reduced to 2 or 3 segments, segmentation indistinct; each leg 30–55 µm long; sometimes with claw on tip, about 3 µm long. Tentorium 70–100 µm long, 70–75 µm wide. Labium 3 segmented, triangular, 60–70 µm long, 40–50 µm wide; labial setae setose: basal segment with 2 pairs about 5 µm long, median segment with 1 pair 17–25 µm long and apical segment with 4 pairs 8 µm long. Spiracles subequal in size, each peritreme 20–25 Μm wide, each crescent-shaped sclerosis 30–50 µm long. Tubular ducts of Type 2 only, with an inner ductule 6–10 µm long, inner cup 5 µm wide and outer ductule 8–10 µm long, arranged in a submarginal band 1 or 2 ducts wide from cephalic apex to anal ring. Quinquelocular pores each 4 µm diameter; with 2 pores anterior to each anterior spiracle; 1 pore anterior to each posterior spiracle. Ventral setae of two types: (i) setose setae: 3 pairs of setae anterior to tentorium, each about 15 µm long; abdominal segments II–VII with setae in medial rows about 8 µm long, and in submedial rows about 5 µm long; 1 seta medial to each coxa 8 µm long.

Microspines, each about 2 µm long, in groups of 1–8 in 5–8 rows on entire body. Anal ring ventral, diameter 35–45 µm, composed of 2 semi-circles, each half with 3 spinose setae about 30 µm long, and 8–12 pores. Anal lobes well-developed and somewhat rounded, with 2 spinose setae about 13 µm long, similar to marginal setae, with 1 on each inner margin and another on apex of each lobe, plus a long thin apical seta 50–65 µm long.
Comments. Among the Palaearctic species, the only other described second-instar females are those of K. bytinskii ( Sternlicht, 1969) , K. williamsi ( Sternlicht, 1970) , K. quercus ( Podsiadlo, 2012) , and K. vermilio ( Pellizzari et al., 2012) . That of N. balachowskii most closely resembles K. echinatus , K. hermonensis , K. quercus and K. vermilio in having reduced antennae and leg segments. However, N. balachowskii has three-segmented antennae and three-segmented legs, whereas K. echinatus has one-segmented antennae and one-segmented legs, K.
hermonensis has five or six-segmented antennae, K. quercus View in CoL has six-segmented antennae and three-segmented legs and K. vermilio View in CoL has three-segmented antennae and one-segmented legs. Also, second-instar female N. balachowskii View in CoL (and K. vermilio View in CoL ) lack frontal lobes, and, like K. echinatus View in CoL , K. hermonensis and K. vermilio View in CoL , N. balachowskii View in CoL , lacks quinquelocular pores ventrally on the abdomen. Other Israeli species, i.e. K. greeni View in CoL , K. nahalali View in CoL and K. spatulatus View in CoL , have six-segmented antennae and well-developed legs, as also found on several Nearctic species, including, K. cockerelli View in CoL , K. concinnulus View in CoL and N. iselini View in CoL and O. secunda ( Baer & Kosztarab, 1985) View in CoL .

Tentorium well-developed, 75–90 Μm long, 63–75 Μm wide. Labium 3 segmented, triangular, 82–100 Μm long, 35–38 Μm wide; labial setae setose, as follows: basal segment with 2 pairs 10–15 Μm long, median segment with 1 pair on dorsal surface 10–20 Μm long, apical segment with 4 pairs 12–17 Μm long. Spiracles subequal in size, each peritreme 3–5 Μm wide, each crescent-shaped sclerosis 15– 25 Μm long. Bilocular pores oval, each 2 Μm long and 1 Μm wide; with 1 pore present between margin and each spiracle.

Comments. There is no unique set of characters that distinguishes the first-instar nymphs of Nidularia from the Palaearctic Kermes examined in this study. Those of N. balachowskii can be distinguished from other Nidularia species by the sharply spinose, apically pointed and slightly curved marginal setae, each 9–15 Μm long; N. pulvinata has setose setae ( Koteja, 1980) and N. japonica has setose setae, somewhat conical at their base ( Kuwana, 1918; Liu et al., 1997).

Comments. The major feature distinguishing the adult male of N. balachowskii from the other five Israeli and Nearctic species is body size. The adult male of N. balachowskii is only 0.8–1.1 mm long and 0.2–0.3 mm wide at metathorax whereas the other species are 1.5–2.0 mm long and 0.4–0.5 mm wide. Nidularia balachowskii can be distinguished from N. japonica by the absence of setae on the prosternum ( N. japonica has eight setae) and the presence of one pair of dorsal setae on the abdominal segments ( N. japonica has two pairs) ( Liu et al., 1997).

As in all known kermesid pupae bar K. hermonensis , the pupa of N. balachowskii lacks quinquelocular pores anterior to each spiracle. Also N. balachowskii has membranous anal lobes, as in all described kermesid pupae apart from K. greeni and K. spatulatus , which have sclerotized anal lobes.

Comments. The prepupa of N. balachowskii is greyish-brown in life, similar to K. nahalali and K. spatulatus but unlike the other Israeli kermesids, K. greeni is orange and K. echinatus and K. hermonensis is red. The prepupa of N. balachowskii has a single quinquelocular pore anterior to each spiracle, while those of K. echinatus and K. hermonensis have two pores. The other Israeli kermesids ( K. greeni , K. nahalali and K. spatulatus ) and the Nearctic species A. kingii ( Hamon et al., 1976) and E. gillettei ( Miller & Miller, 1993) lack spiracular pores.

Comments. The second-instar males of the other two Nidularia species, N. japonica and N. pulvinata , have not been described. Nidularia balachowskii lacks the anal lobes found on K. greeni and K. nahalali and has no frontal lobes, as found in Kermes echinatus , K. hermonensis and K. vermilio ( Pellizzari et al., 2012) . In addition, what distinguishes N. balachowskii from other Israeli kermesids is the presence of three quinquelocular pores associated with each spiracle. All the other species have more or fewer than three pores: K. echinatus (4) K. greeni (five), K. hermonensis (eight), K. nahalali (eight), K. quercus (4–9) ( Podsiadlo, 2012), K. spatulatus (five) and K. vermilio (two) ( Pellizzari et al., 2012). The Nearctic second-instar males of K. cockerelli , K. concinnulus and K. rimarum differ in having long, setose marginal setae and, unlike N. balachowskii which only has quinquelocular pores on the venter, have them scattered on both the dorsum and venter ( Baer & Kosztarab, 1985).
