A new species of armored scale insect, Aulacaspis fanjingshanensis sp. nov. is described and illustrated based on adult female specimens collected on Rosaceae plants in China. A key to the Aulacaspis species known from Guizhou Province of China is provided. Our molecular study suggests that Aulacaspis schizosoma (Takagi, 1970) is not a true member of the genus Aulacaspis; the genus Superturmaspis Chen, 1983 is revived and A. schizosoma is transferred to it as Superturmaspis schizosoma (Takagi, 1970), revived combination, based on a molecular phylogeny.
Armored scale insect, molecular phylogenetic analysis, new record, pest, taxonomy
Diaspididae, the largest family of Coccomorpha with more than 2700 species (
The genus Aulacaspis Cockerell, 1893 belongs to the Chionaspidina, within the tribe Diaspidini, in the subfamily Diaspidinae (
One hundred and fifty-one species of Aulacaspis have been recorded in the world and distributed worldwide (
Guizhou Province in China has a subtropical monsoon climate, with rich species resources (http://invest.guizhou.gov.cn/tzgz/tzgk/). Hitherto, seven Aulacaspis species are currently recorded in Guizhou Province, namely A. crawii (Cockerell), A. guiyangensis Tian & Xing, A. longanae Chen, Wu & Su, A. paralonganae Tian & Xing, A. saigusai Takagi, A. yabunikkei Kuwana and A. zunyiensis Wei (
Aulacaspis was placed in Chionaspidina by
Recently, a new species of Aulacaspis was discovered in Guizhou Province of China, and it is described and illustrated herein. And molecular study revealed the need for the resurrection of the genus Superturmaspis Chen, which was synonymized with Aulacaspis by
Samples of plants infested by the new species described in this study were collected in Fanjing Mountain (Guizhou Province, China). Permanent slide mounts of adult females from the samples were made according to
Each specimen was subjected to a joint molecular/morphological preparation protocol that resulted in genomic DNA from a single specimen and a permanent slide-mount of its cuticle (

Prosoma. Prosoma with anterior margin rounded and with sides nearly parallel; peribuccal scleroses well formed. Antennae separated by 60–67 µm; each antenna with 1 seta. Anterior spiracles each associated with 24–27 trilocular disc pores; posterior spiracles each with 3–7 disc pores. Pygidial lobes. With 3 pairs of lobes; L1 well developed, largely sunken into apex of pygidium, base of each L1 with a mesad linear extension onto ventral derm, these extensions separated from each other by a narrow space; L1 elongate and divergent, widest separation distance 19–22 µm, divergent mesal margins minutely serrate, lobe apices blunt or rounded.

Ventral microducts scattered on pygidium, few. Marginal gland spines on each side numbering 2‒4 on segment IV, and 1 on V; also, with 1 lateral to each pygidial lobe. Each side with lateral gland spines numbering 5‒7 on segment II, and 6–13 on segment III. Perivulvar pores in five groups, with 10–17 in the median group, 20–26 in each anterolateral group and 27–35 in each posterolateral group.

The specific epithet is formed by a combination of Fanjing Mountain, the type locality, and the Latin “-ensis”, meaning “from”.
China (Guizhou Province).
Aulacaspis fanjingshanensis sp. nov. is similar to other species in the Yabunikkei complex (A. yabunikkei Kuwana, 1926, A. shirodamo Takagi, 2014 and A. neolitseae Takagi, 2014) by the form of its body shape, but can be distinguished from A. yabunikkei by the following characteristics of the adult female (character-states of A. yabunikkei in brackets): (1) dorsal microducts present on abdominal segment II to head (absent); (2) marginal macroducts of abdominal segment VII scarcely or only a little extending anteriorly beyond bases of these extensions (extending); and (3) median lobes separated from each other by a narrow space (united basally).
The stable diagnostic characters that distinguish A. fanjingshanensis sp. nov. from A. shirodamo and A. neolitseae are very few. The differences are the presence of dorsal microducts that are found from the head region down to abdominal segment II and median lobes separated from each other by a narrow space.

We confirmed the non-monophyly of the genus-level relationships and taxonomy of Chionaspidina, including the genera Aulacaspis and Chionaspis (
Our phylogenetic study has demonstrated that the type species of Aulacaspis and Chionaspis (A. rosae and C. salicis) are more closely related to each other than either is to Superturmaspis schizosoma. Hence, A. schizosoma was wrongly assigned to Aulacaspis (Figs
We transferred the species back to Superturmaspis based on our molecular analysis. Superturmaspis was previously established by Chen, 1983, and included only one species, Superturmaspis schizosoma. The adult female specimens (Fig.
