Other leg segments with spinose and flagellate setae; tarsi each with a sensory pore. Claws without a denticle. Anterior and posterior spiracles each with a large group of five-locular pores in atrium; width of anterior peritreme 26 µm. Multilocular pores each 5 µm in diameter, with 5–9 loculi (usually 5), scattered medially on posterior abdominal segments and head, and also in a wide submedian band on all segments. Abdomen with a few flagellate setae medially, plus a marginal band of large spines and several spinose setae in a submarginal band. Cruciform pores absent. Microtubular ducts few, in a fairly narrow submarginal band. Macrotubular ducts few, present in a submarginal band and medially on thorax and head; each duct with inner ductule shorter than outer ductule; inner ductule with a flower-like terminal gland. Spinulae present only on abdomen. Vulva unclear.

Segment VII with weak submedian sclerotization.

Dorsum. Dorsal setae conical and spinose, of two sizes: largest setae along margin, robust, with 2 on each abdominal segment, each 41–52 µm long, intermixed with smaller setae, each about 21 µm long; also with long and short setae in a longitudinal median band, with 4 to about 14 setae on each segment, each seta 19–43 µm long; some small spinose setae also present submedially on head and thorax. Shorter, less strongly spinose setae, each 12–16 µm long, sparse on most segments. Macrotubular ducts each 18–25 Μm long, 2–3 Μm wide, abundant throughout. Microtubular ducts each 14 µm long and less than 1 Μm wide, with a bilocular inner end, scattered among dorsal setae, and sometimes with 1 or 2 present at base of a few large spinose setae. Anal ring unclear, 48 Μm wide, 52 Μm long, with a sparse row of pores along outer margin; with 8 flagellate setae, each about 125 µm long. Anal lobes large, sclerotized, 156 µm long and 127 µm wide, with a spinose seta on both inner and outer margins, inner seta 36 Μm long, outer seta 41 µm long, and a longer apical seta, 50 µm long. Anal lobes with dorsal surface covered with sclerotized protuberances, each protuberance with a microtubular duct; inner margin of lobes with sclerotized teeth. Spinulae present only on last abdominal tergites. Cauda present medially at base of anal lobes, 17–25 µm wide, and about twice as long as wide. With two areas of dense sclerotisation submedially on segment VII, each with strong protuberances and an associated microduct.

Comment. For comparison with P. m a r t i n i, see under that species.

Etymology. The new species is named after the late Professor Dr. János Balogh from Hungary, in acknowledgement of his collecting efforts that have yielded several important new Eriococcidae , including the present species.

Anterior and posterior spiracles each with a large group of five-locular pores in atrium; width of anterior peritreme 15 µm. Multilocular pores each with 5–9 loculi (mostly 5-locular), 4 µm in diameter, scattered medially on posterior abdominal segments and head, and also forming a longitudinal submedian band on all segments. Abdominal margin with a row of robust spines; lanceolate setae present on midventer, plus several small spinose setae in a submarginal band. Cruciform pores absent. Microtubular ducts few, in a submarginal band associated with spinose setae. Macrotubular ducts absent. Each anal lobe with a large spinose suranal seta 53 Μm long, a shorter ventral spinose seta medially 24 Μm long, and a long seta in a submarginal position (broken). Segment VII with an area of weak sclerotization submedially. Dermal spinules present on abdominal segments.

Dorsum. Dorsal setae conical and spinose, of two sizes: largest setae robust, in a line along margin, with 1 seta per segment on abdomen but more on anterior segments, each 31–37 µm long; also with 2–8 medially on each segment in a longitudinal band, each 14–17 µm long. Shorter setae each 7–9 µm long, present in a sparse row on most segments. Macrotubular ducts absent. Microtubular ducts each 11 µm long, and less than 1 Μm wide, with a bilocular inner end; scattered among dorsal setae, and sometimes with 1 or 2 at base of some larger spinose seta. Anal ring unclear, 28 Μm wide, 32 Μm long, with a sparse row of pores along outer margin; with six flagellate setae, each 98 µm long. Anal lobes large, sclerotized, 77 µm long, 77 µm wide, each with a spinose seta on both inner and outer margins, inner seta 22 µm long, outer seta 19 Μm long, plus a spine in apical position (broken). Anal lobes with dorsal surface covered with sclerotised protuberances, each with a microtubular duct; inner margin of lobes with serrate sclerotized teeth. Cauda present medially at base of anal lobes, 12–22 µm wide, about twice a long as wide. Area of strong sclerotisation present submedially on segment VII. Dermal spinules absent on dorsum.

Comment. The 2nd -instar female nymphs of P. baloghi differ from those of P. m a r t i n i in having (characters states on P. martini in brackets): (i) both setae on trochanter flagellate (one spinose and one flagellate), (ii) metacoxae without translucent pores (present), and (iii) protuberances on dorsal surface of anal lobe and VIIth abdominal segment with associated microtubular ducts (absent).
