No full textUnaspis fanjingensis sp. n. (Figs 8–16) Material studied. Holotype female: CHINA, Guizhou Province, Tongren city, Fanjing Mountain, on Berberidaceae and Litsea (Lauraceae) leaves, coll. Zeng, 18.viii.1996 (at NWAFU; first specimen at the left end of a row of 4 adult females, clearly mapped on the slide label). The other 3 specimens are paratypes. Paratypes female: CHINA, same data as holotype (at NWAFU; a total of 12 adult females, as follows: 3 specimens on the slide containing the holotype; 2 slides each containing 4 adult females; and 1 slide containing 1 adult female). Description of slide-mounted adult female: the figures provided below are for the holotype specimen, and (holotype + 8 paratype specimens, range and mean value). Body fusiform, widest at abdominal segments I and II. Antennae tuberculate, each with 1 seta and two cusps. Anterior spiracles each with 28–31 parastigmatic pores; posterior spiracle without associated parastigmatic pores. Conical duct tubercles present on metathorax and abdominal segments I–III (each side with 1 on mesothorax, 1–4 on metathorax, 7–11 on segment I, 9 or 10 on segment II, and 7 or 8 on segment III). Prepygidial abdominal segments each with gland spines (4 on segment II, 5 on segment III and 3 on segment IV). Pygidium rounded, with 3 pairs of well-developed lobes. Median lobes with basal parts of median margins connected by a sclerosis and inner and outer margins serrate. Second and third lobes much smaller than median lobes, each deeply bilobed with outer lobule smaller than inner lobule. Fourth lobes reduced, very small. Marginal macroducts larger than dorsal ducts, absent from between median lobes; each side with 7: with 1 between median and second lobes, 1 between second and third lobes, 1 between lobules of third lobe, 2 by fourth lobe and 2 on segment IV. Pygidium with four single marginal gland spines on each side, 1 between median and second lobes; 1 between second and third lobes, 1 between third and fourth lobes, and 1 lateral to fourth lobe. Dorsal macroducts scattered on segments as far forward as mesothorax, numbering 60–80 over entire body. Dorsal macroducts located in the lateral margin on metathorax and segments I and II and arranged on submarginal and submedian areas of segments III, IV and V. Ventral microducts scattered over entire body, numbering 90–100 on entire body. Anus rounded, rather small, situated near centre of pygidium. Perivulvar pores present in 5 groups; with about 16 in median group, 24–29 in each anterolateral group, and 18–20 in each posterolateral group. Host. Berberidaceae, Litsea (Lauraceae). Etymology. The specific epithet is formed by a combination of Fanjing Mountain, the type locality, and the Latin “- ensis ”, meaning “from”. Distribution. China (Guizhou Province). Comments. Unaspis fanjingensis sp. n. is very similar to U. mediforma but di?ers in having (character-states on U. mediforma in brackets): (i) anterior spiracle with 28–31 parastigmatic pores (5–8 pores); posterior spiracle without parastigmatic pores (2–4 pores); (ii) gland spines on pygidium between pygidial lobes each with single point at apex (each with apex split into 2 or 3 points).Published as part of Niu, Minmin & Feng, Jinian, 2019, Two new species of the genus Unaspis MacGillivray, 1921 (Hemiptera: Coccomorpha: Diaspididae) from China, pp. 573-580 in Zootaxa 4555 (4) on page 576, DOI: 10.11646/zootaxa.4555.4.8, http://zenodo.org/record/258536
