Pinnaspis chamaecyparidis Takagi, 1961

( Figures 1A–F )

Pinnaspis chamaecyparidis Takagi, 1961: 72–73 . Type data: Japan, on Chamaecyparis obtusa , 8-i-1955 and 16-iv-1956.

Field Characters. Adult female cover narrowly to broadly oyster-shell shaped, light to dark brown; shed skins margin, yellow brown to brown. Male cover smaller, felted, white, elongate, with slight median carina; shed skin yellowish.

Slide-mounted Characters. Adult female with 2 pairs of well developed lobes, third lobes inconspicuous; paraphyses attached to medial margin of median lobules of second lobe. Median lobes small in size, closely appressed together, slightly elongate with 1–2 deeply lateral notches, the basal zygosis robust, and distinctly produced anteriorly into apex of pygidum; second lobes with 2 lobules, medial lobules slightly expanded apically, with a pair of slender basal scleroses. Gland spine formula 1–1–1, with about 14 gland spines near each body margin from segments 5 to 7. Macroducts of 2 sizes, larger size in marginal areas on segments 4 to 7, in submarginal areas on segments 1 to 3, smaller size in submarginal and marginal areas from metathorax to segment 3. Perivulvar pores in 5 groups, 38–48 pores. Perispiracular pores usually with 3 loculi, anterior spiracles each with 3–6 pores, posterior spiracles with 1–2 pores. Anal opening located about middle of pygidium. Antennae each with 1 conspicuous seta. Body elongated fusiform with prepygidial segments each slightly convex laterally. Preanal scars absent.

Affinities. This species is most similar to Pinnaspis juniper Takahashi which is not known to occur in Korea, from which it differs mainly by the second lobes which are well developed, with the inner lobule slightly expanded apically.
