Pseudaulacaspis latiloba (Takagi and Kawai)

( Figures 7–12 )

Phenacaspis latiloba Takagi and Kawai, 1966: 112 . Type data: Japan, on Carpinus laxiflora .

Description. Field Characters. Adult female cover white, oyster-shell shaped; shed skins marginal, yellow to brown. Male not examined by author.

Slide-mounted Characters. Adult female with 2 or 3 pairs of well developed lobes, third lobes reduced or represented by series of low points. Median lobes prominent, robust, broadly rounded with medial yoke, divergent, with minute notches; second lobes with 2 lobules smaller than median lobes, rounded, much shorter than median lobes. Gland spine formula usually 0–1–1, with about 6 gland spines near each body margin from segments 5 to 7. Macroducts on pygidium about same size without duct between medial lobes, with 8–10 macroducts on each side of body on segments 5 to 7; submedial ducts on segments 3 to 4, with 6 to 7 ducts each; submarginal ducts on segments 2 to 4, with 10 to 14 ducts each. Perivulvar pores in 5 groups, about 77 pores. Perispiracular pores usually with 3 loculi, anterior spiracles each with 13–27 pores, posterior spiracles each with 6–10 pores. Anal opening located at upper of pygidium. Antennae each with 1 conspicuous seta; usually separated by more than maximum width of median lobes. Body robust fusiform with prepygidial segments little convex laterally. Only found on Carpinus plants.

Material examined. Korea. JN: Wando-arboretum, 11 adult females on three slides, on Carpinus laxiflora (Betulaceae) bark, 10-v-2007 (S.J. Suh); Jirisan, 2 adult females on one slide, same host, 3-vi- 2011 (S.J. Suh).
