Li, Wen-Chao & Wu, San-An, 2014, A new species and a new record of the genus Balanococcus Williams (Hemiptera: Coccoidea: Pseudococcidae) from China, Zoological Systematics 39 (2), pp. 269-274 : 270-272

3.1 Balanococcus zhejiangensis sp. nov. ( Fig. 1 )

Body of adult female on slide elongate oval, sides almost parallel, about 2.05–3.12 (2.10) mm long and 0.66–1.25 (0.66) mm wide. Anal lobes prominent, each with ventral surface bearing an apical seta 110–130 (120) μm long, 1.9 times as long as seta on anal ring. Antennae each about 280–300 (280) μm long, with 7 segments, apical segment longest, with 2 fleshy setae. The ratio of length for each segment: I-12; II-16; III-12; IV-17; V-12; VI-13; VII-34. Eye spot present. Labium with 1 segment, 80–100 (90) μm long, 7/10 of length of the clypeolabral shield, each side with 5 stout setae. Legs developed, 2 setae present under end of tibia, claw slender, without denticle, both tarsal digitules and claw digitules knobbed, longer than claw. Hind coxa 60–100 (90) μm long, larger than fore or middle coxa, with translucent pores on anterior and posterior surfaces and derm anteriorly next to hind coax, forming pore plate; hind trochanter and femur 160–190 (190) μm long, nearly equal to length of tibia and tarsus (190–200 (200) μm); ratio of lengths of hind tibia to tarsus 1.6. Circulus small and almost circular, 30–40 (30) μm in diameter, lying between abdominal segments III and IV. Ostioles with anterior and posterior pairs, each lip with 3–4 trilocular pores. Anal ring present at the end of body, 70 μm wide, with 2 rows of cells and 6 setae, each seta 60–70 (60) μm long. A pair of cerarii on anal lobes only, each containing 2 conical setae and 2–3 trilocular pores, situated on a membranous area.

Dorsum. Dorsal surface with flagellate setae, but fewer than those on ventrum, each side of abdominal segments V–VII with 1 stout flagellate seta on margin. Multilocular disc pores in groups present on submarginal areas of abdominal segments V–VIII. Trilocular pores present, evenly and widely spaced. Oral collar tubular ducts of one size, 6.0 μm long and 2.5 μm wide, present on submarginal areas of abdominal segments V–VII.

Ventrum. Flagellate setae on ventrum longer than those on dorsum, each side of abdominal segments V–VII with 1 long flagellate setae on margin. Multilocular disc pores, froming marginal band from prothorax to the end of the abdomen, transverse row or band across posterior edges of abdominal segments V–VIII, and sometime a few present interior to hind

Oral collar tubular ducts of 2 sizes, the large one, 6.0 μm long and 4.0 μm wide, forming longitudinal band along margin; the small one, same as those on dorsum, forming narrow transverse band on abdominal segments IV–VII.

Holotype ♀, China, Zhejiang Province, Lin’ an City (30°14′N, 119°42′E), under the leaf sheath of Phyllostachys praecox , 9 April 1999, San-An Wu leg. Paratypes 4 ♀♀, same data as holotype .

Host plant. Phyllostachys praecox .

Remarks. The new species is similar to B. kwoni Pellizzari & Danzig, 2007 , but hind coxae each are extremely wider than fore or middle coxae; only the same size of ducts present on the dorsal surface.

Etymology. This new species is named after the province name of its collecting locality.
