Material examined

Holotype: adult female:CHINA:Guizhou Prov., Zhenyuan County, 13. viii. 1996, Zeng (NWAFU).
Paratypes: 2 adult females: same data as the holotype (NWAFU).

Description

, n=3. Adult female. Appearance in life not recorded. Slide-mounted adult female 1755-1910 μm long (holotype 1910 μm long); 930-970 μm wide (holotype 931 μm wide), body outline fusiform, derm membranous except for pygidium. Normally widest at metathorax and abdominal segment I, lateral abdominal lobes well-developed, with large gland spines on the margin of prepygidial and pygidial segments. Cephalothorax. Antennae each with 1 long fleshy seta, distance between antennae is 111 µm. Anterior spiracle each with 12-31 trilocular pores in a cluster, posterior spiracle each with 11-17 trilocular pores. Pygidial Lobes. With 3 pairs of lobes; L1 well-developed, zygotic basally, protruding from pygidial margin, with small serrations along both margins, with a pair of setae between lobes; L2 bilobate, inner lobule rounded, much larger than outer lobule; L3 bilobate, slightly smaller than L2, inner lobule rounded, outer lobule margin serrate; L4 represented by serrations along the body margin. Gland spines. Large, arranged singly on pygidial segments VI-VIII but with 2 on segment V, 4-5 on segment IV, 5-6 on segment III, 5 on segment II, anterior spines smallest (on segment II). Gland tubercle present submarginally, with 2 on prothorax, 9-11 on mesothorax, 5-6 on metathorax, 6 on segment I. Ducts. Marginal macroducts, 2-barrel-shaped, 1 present between L1 and L2, 2 on segment VI, 1 on segment V. Dorsal macroducts on pygidium about same size as marginal macroducts, becoming slightly smaller on anterior abdomen, 2-barrel-shaped, arranged segmentally in submedian and submarginal rows; submedian: 3-6 on segment I, 4-5 on II, 4-6 on III, 7-13 on IV, 3-4 on V; submarginal: 11-14 on I, 11-12 on II, 10-11 on III, 10-11 on IV, 8-9 on V. Dorsal ducts scattered on margin of thorax, smaller than those on abdomen, 2-barrel-shaped, with 8 or 9 on prothorax, 15-17 on mesothorax, 14 or 15 on metathorax. Dorsal ducts on head as big as ventral microducts, very smaller than dorsal ducts present on thorax, scattered distribution. Ventral microductsscattered, numerous on head and with several microducts on submargin of pygidium and prothorax and submedian of abdomen, meso- and metathorax. Anal opening, small, 15-17µm in diameter, positioned 214 µm from posterior margin. Perivulvar pores in 5 groups, 31-37 in the median group, 33-44 in the anterolaterally and 45-48 in the posterolaterally.

Diagnosis

This species is similar to Pseudaulacaspis chinensis (Cockerell, 1896) in body shape and the number of pygidial lobes, but can be distinguished by the following features (those for Pseudaulacaspis chinensis in brackets): 1) dorsal macroducts absent on abdominal segment VI (present); 2) L1 prominent the pygidium (sunken into the pygidium).
Host: Spermadictyon suaveolens.

Etymology

The specific epithet is named after Zhenyuan, the type locality.

Distribution

China (Guizhou).
