Four aleyrodid species, Aleuroclava montanus (Takahashi), Asterobemisia atraphaxius (Danzig), Pentaleyrodes

 yasumatsui Takahashi, and Rhachisphora styraci (Takahashi) are newly recorded in the Korean fauna of 

whiteflies (Aleyrodidae).

Introduction

Whiteflies (Aleyrodidae) of about 1556 species belonging to 161

genera worldwide have been listed (Evans, 2008; Martin and

Mound, 2007). Even though they are a small group, aleyrodids have

recently become one of the most economically important groups of 

insect pests on crops and ornamental plants. Due to the increase in

importation of plant materials from various countries, Korean

agriculture may be threatened by the introduction of invasive

whitefly species. The proper evaluation of the potential threat of a

whitefly species intercepted on imported products and the

determination of the appropriate response or action that needs to

be taken, require the knowledge of which species of whiteflies are

already known to occur in Korea. Twenty species in 13 genera of 

whiteflies have been documented from Korea (Lee et al., 2005; Suh

and Hodges, 2005).This paper records the occurrence of additional species of 

whiteflies, namely, Aleuroclava montanus (Takahashi), Asterobemisia

atraphaxius (Danzig), Pentaleyrodes yasumatsui Takahashi, and Rha-

chisphora styraci (Takahashi) in Korean fauna, and provides

illustrations, brief descriptions and information on the distribution

and hosts of each species. An asterisk (⁎

 Aleuroclava montanus (Takahashi) (Figs. 1–3)

Taiwanaleyrodes montanus Takahashi 1939

Diagnosis

Black puparium, not very sclerotised on the median area of dorsum

(Fig. 1). Submargianl area without markings, which are parallel to the

mesal wavy margin (Figs. 1 and 2). Caudal furrow distinct, slightly

narrowed towardsthe hindend. Vasiformorifice rather large andcircular.

Anterior marginal area of the vasiform orifice expanded (Fig. 3)

(Takahashi, 1939).

Specimens examined

Korea. Jejudo: Seongpanak, 3 puparia (on the underside of leaf), on

Daphniphyllum teijsmanni, 20.x.2005 (S.J. Suh).

Distribution

⁎Korea and Taiwan.

Host plants

⁎Daphniphyllum teijsmanni Zollinger ex Kurg (Daphniphyllaceae).

An unidentified species of Lauraceae was listed as the host of this

species in Taiwan (Takahashi, 1939).

 Asterobemisia atraphaxius (Danzig) (Figs. 4–6)

Neobemisia atraphaxius Danzig 1969

Diagnosis

Black puparium. Transverse moulting suture curved, directed

anteriorly, joined at the anterior end of body to form a closed

figure (Fig. 4). Abdominal segmentation distinct, rhachis faint

and forming short ridges (Fig. 5). Caudal furrow undeveloped

(Fig. 6).

Specimens examined

Korea. Chungcheongnamdo: Anmyeondo, 9 puparia (on the

underside of leaf), on Polygonum sp., 15.ix.2006 (S.J. Suh).

Distribution

Iran, ⁎Korea, Russia and Europe.

Host plants

Polygonum sp. (Polygonaceae). In addition twelve different plant

families were listed as hosts (Evans, 2008).

 Pentaleyrodes yasumatsui Takahashi (Figs. 7–10)

Pentaleyrodes yasumatsui Takahashi 1939

Diagnosis

Black puparium. Prominent paler areas at the ends of the

transverse suture between the thorax and abdomen, with 2 pairs

of pale patches on the cephalothorax (Figs. 7 and 8). Dorsum with

16 pairs of long fine setae, arising from a very small-tubercle,

arranged in a single row along the entire submargin (Figs. 8 and

9). Caudal furrow long, very narrow, expanded at the base

(Fig. 10).

Specimens examined

Korea. Jeollanamdo: Wando-arboretum, 6 puparia (on the

underside of leaf), 1 female and 1 male adults (reared), on Per-

sea japonica, 1.vi.2007 (S.J. Lee); Bogildo, 1 puparium (on the

underside of leaf), on P . japonica, 18.iv.2008 (S.J. Suh); same
