Introduction

The aphid genus Parathoracaphis was erected by Takahashi (1958), with Thoracaphis setigera Takahashi, 1932 as the type species, based on the morphological characters that head and thorax are completely fused with abdominal segments I–VII, dorsum lacks pustules but bears spine-like submarginal setae, and siphunculi absent. Thoracaphis elongata Takahashi, 1941 and Thoracaphis kayashimai Takahashi, 1950 were also assigned to this genus (Takahashi 1958). Eastop and Hille Ris Lambers (1976) subsequently included two other species, Thoracaphis cheni Takahashi, 1936 and Thoracaphis gooti Takahashi, 1950, under Parathoracaphis. Ghosh (1988) considered HoplothoracaphisPramanick, Samanta & Raychaudhuri, 1983 as a synonym of Parathoracaphis, and consequently referred Hoplothoracaphis manipurensis Pramanick, Samanta & Raychaudhuri, 1983 to Parathoracaphis.

Herein, a new species Parathoracaphis spinapilosa sp. n. is described, found on Quercus sp. and an unidentified species of Fagaceae in Fujian and Yunnan, China. Therefore, the genus Parathoracaphis now includes seven species: P. cheni (Takahashi), P. elongata (Takahashi), P. gooti (Takahashi), P. kayashimai (Takahashi), P. manipurensis (Pramanick, Samanta & Raychaudhuri), P. setigera (Takahashi), and P. spinapilosa sp. n.

Materials and methods

Morphological description. Aphid terminology in this paper generally follows Takahashi (1958) and Ghosh (1988). The unit of measurements is millimetres (mm). In Table 1, the following abbreviations are used: Ant.IIIBD, basal diameter of antennal segment III; URS, ultimate rostral segment; BW URS, basal width of ultimate rostral segment; 2HT, second hind tarsal segment; BW Cauda, basal width of cauda.

Parathoracaphis Takahashi, 1958: 13. Type species: Thoracaphis setigera Takahashi, 1932; by original designation.

Hoplothoracaphis Pramanick, Samanta & Raychaudhuri, 1983: 1. Type species: Hoplothoracaphis manipurensis Pramanick, Samanta & Raychaudhuri, 1983; by monotypy.

Parathoracaphis Takahashi: Ghosh and Raychaudhuri 1973: 486; Eastop and Hille Ris Lambers 1976: 336; Ghosh 1988: 194; Tao 1990: 71; Blackman and Eastop 1994: 799; Remaudière and Remaudière 1997: 188; Tao 1999: 22; Nieto Nafría et al. 2011: 305.

Generic diagnosis

In apterae, body elongate oval, oval, or subcircular, aleyrodiform, and strongly sclerotized. Prosoma consisting of fused head, thorax, and abdominal segments I–VII, abdominal segment VIII free. Dorsum of prosoma reticulated, corrugated, convoluted, or with wax pores. Submarginal setae on dorsal prosoma distinctly spine-like, pointed or somewhat blunt at apices, sometimes arising from tuberculate bases. Dorsal spinal setae on prosoma minute, long and fine, or spine-like. Abdominal tergite VIII with 4 setae, similar to submarginal setae on dorsal prosoma. Eyes 3-faceted. Antennae concealed under head, 2–4-segmented. Legs short, concealed under body; tarsi small, unsegmented or 2-segmented; claws small, normal, or absent. Siphunculi absent. Cauda knobbed and constricted at base. Anal plate bilobed.

Distribution

China, India, Japan, Malaysia, and Thailand.

Host plants

Fagaceae (Castanopsis, Cyclobalanopsis, Lithocarpus, and Quercus) and Lauraceae (Litsea).

Comments

Only apterous viviparous females are known. The life cycles of most species are unknown. Parathoracaphis is related to Neohormaphis Noordam, 1991 in sharing the consolidated head, thorax, and abdominal segments I–VII and spine-like submarginal setae on prosoma.

Parathoracaphis cheni (Takahashi, 1936)

Thoracaphis cheni Takahashi, 1936: 21.

Parathoracaphis cheni : Eastop and Hille Ris Lambers 1976: 336; Blackman and Eastop 1994: 799; Remaudière and Remaudière 1997: 188; Tao 1999: 22.

Specimens examined

Twelve apterous viviparous females, CHINA: Zhejiang (Huangyan), Jan 1934, on Myrica rubra, coll. F.G. Chen (NHM).

Distribution

China (Zhejiang).

Host plant

The host plant is recorded as Myrica rubra with a question mark in the original description (Takahashi 1936). We think it may be an erroneous record.

Biology

Sitting tightly on the undersides of leaves of host plant (Takahashi 1936, Blackman and Eastop 1994). The life cycle is unknown.

Parathoracaphis elongata (Takahashi, 1941)

Thoracaphis elongata Takahashi, 1941: 22.

Parathoracaphis elongata : Takahashi 1958: 14; Ghosh and Raychaudhuri 1973: 486; Eastop and Hille Ris Lambers 1976: 336; Blackman and Eastop 1994: 799; Remaudière and Remaudière 1997: 188.

Distribution

Thailand.

Host plants

Quercus sp. and other unspecified Fagaceae species.

Biology

This species occurs in large numbers on the undersides of leaves of host plant (Takahashi 1941). The life cycle is unknown.

Comments

Known only from the original description. Takahashi (1941) mentioned that the dorsal prosoma of this species has 5 pairs of spine-like spinal setae, tarsi are unsegmented, and claws are absent.

Parathoracaphis gooti (Takahashi, 1950)

Thoracaphis gooti Takahashi, 1950: 605.

Parathoracaphis gooti : Eastop and Hille Ris Lambers 1976: 336; Blackman and Eastop 1994: 799; Remaudière and Remaudière 1997: 188.

Distribution

Malaysia.

Host plant

Quercus sp.

Biology

Infesting the undersides of leaves of host plant (Takahashi 1950). The life cycle is unknown.

Comments

Known only from the original description. The figure in Takahashi (1950) indicates that the dorsal prosoma of this species has 16 pairs of spine-like submarginal setae and 5 pairs of long and fine spinal setae, a pair of submarginal setae on head dorsum located near the front end, and 2 pairs between the eyes. The original description mentioned that the antennae of P. gooti are 3- or 4-segmented, the tarsi are distinctly 2-segmented, and the claws are slender.

Parathoracaphis kayashimai (Takahashi, 1950)

Thoracaphis kayashimai Takahashi, 1950: 602.

Parathoracaphis kayashimai : Takahashi 1958: 14; Ghosh and Raychaudhuri 1973: 486; Eastop and Hille Ris Lambers 1976: 336; Blackman and Eastop 1994: 799; Remaudière and Remaudière 1997: 188.

Distribution

Malaysia.

Host plant

Quercus sp.

Biology

Feeding on the undersides of leaves of host plant (Takahashi 1950). The life cycle is unknown.

Comments

Takahashi (1950) mentioned that P. kayashimai was closely related to P. setigera, differing in ornamentation of dorsum and leg measurements. The key to Nipponaphidini species on Quercus and the figure of P. kayashimai in Blackman and Eastop (1994) indicate that submarginal setae on abdominal tergite VI of this species are much smaller than setae on other tergites.

Specimens examined

One apterous viviparous female, CHINA: Yunnan (Chuxiong City, Mt. Zixi), 22 Oct 2010, No. 24888, on Castanopsis sp., coll. X.L. Huang (NZMC); 1 apterous viviparous female, CHINA: Yunnan (Chuxiong City, Mt. Zixi), 22 Oct 2010, No. 24894, on Fagaceae, coll. X.L. Huang (NZMC).

Distribution

China (Yunnan), India.

Host plants

Castanopsis sp. and Litsea sebifera.

Biology

Forming large colonies on the undersides of leaves of host plant, attended by ants sometimes (Fig. 2). Apterous adults bear much filiform and flocculent wax (Fig. 3). The life cycle is unknown.

Figures 1–3.

Comments

Ghosh (1988) described an apterous morph on Amaranthus sp. (Amaranthaceae) as a fundatrix of P. manipurensis. However, the specimen was not collected at the type locality, no life cycle observations were conducted, and Amaranthus sp. is unlikely to be a primary host plant of Nipponaphidini species. Additionally, the presence of siphunculi suggests that it does not belong in Parathoracaphis.

In Japan, apterae occur on undersides of leaves of Quercus throughout the year (Takahashi 1958).
