Parlatoria menglaensis  sp. n. Figures 1-9

Material examined.

Holotype and 30 paratypes, adult female. China: Yunnan Province. Mengla city, longitude 101.57, latitude: 21.48, on Cinnamomum camphora  (L.) Presl., 30.vii.2017, coll. Minmin Niu.


Female scale. Adult female cover convex, circular dark green/grey; exuvia on front end. Male scale. Not recorded.

Adult female. Body elongate-ovate, the broadest in first abdominal segment or thoracic region; segmentation distinct.

Antenna composed of two stout tubercles and a seta, located midway between frontal margin and mouthparts, interantennal distance being equal to width of mouth-parts. Prosomatic tubercles absent. Anterior spiracle with 1-2 parastigmatic pores; posterior spiracle without pores. Derm pocket absent between the posterior spiracle and body margin. Submarginal duct tubercules arranged as follows: 1-2 on cephaloprothoracic sternum, 3-5 on the mesothorax, and 4-8 on the metathorax.

Pygidium rounded, with 3 pairs of well-developed lobes. The median lobes distinctly notched once on each side, the second and third usually notched once distinctly on outer side. Fourth lobes replaced by a fimbriate plate, similar to adjacent fimbriate plates in form. Fimbriate plates present throughout pygidium, mostly as long as lobes, and two between median lobes, two between the median and second, three between the second and third; pygidial marginal macroducts largest closer to median lobes, arranged as follows: absent between the median lobes, one in each interlobar space, two outside the third lobe. Submarginal dorsal ducts on prepygidium numerous, 60-70 ducts on each side. Submedian ducts absent. Ventral microducts few, scattered on pygidium. Anal opening small, positioned about centre of pygidium. Perivulvar pores present in five groups; 3-4 in the median group, laterocephalic group with four pores, and the laterocaudal group with four pores.


This species is very similar to P. machilicola  ( Takahashi 1933) in body shape, but differs in having (character-states on P. machilicola  in brackets): (i) perivulvar pores present in five groups (perivulvar pores present in four groups); (ii) dorsal macroducts absent (dorsal macroducts present); (iii) marginal macroducts only four on each side (marginal macroducts more than four on each side).

The new species also resembles P. tsujii  Tanaka, 2010, in the shape and spiracles. However, it differs from P. tsujii  by the following characters (character-states on P. machilicola  in brackets): (i) perivulvar pores present in five groups (perivulvar pores present in four groups); (ii) derm pocket absent (derm pocket present); (iii) marginal macroducts absent between the median lobes (marginal macroducts present between the median lobes).

Host plant.

Cinnamomum camphora  (L.) Presl ( Lauraceae  ).


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