Fiorinia pinicola Maskell, 1897

Field characteristics.

First-instar exuviae overlapping second-instar exuviae. With indentation formed between attachment of first- and second-instar exuviae. Second-instar exuviae oval, convex marginally; medium to dark brown; longitudinal ridge conspicuous. Posterior end of adult female within second-instar exuviae rounded. Heavily infested leaves with white secretion (Suppl. material 1: Fig. S1).

First-instar nymph.

Described in Howell (1977).

Second-instar female.

Median lobes broad, as wide as or wider than medial lobule of second lobe, projecting ca. same amount as medial lobule of second lobes. With five pairs of marginal macroducts. Swelling of body margin adjacent to macroduct usually pointed. With four large gland spines on margin of each side of body from abdominal segments II-V; usually without small gland spine on each side of abdominal segment VI; with small gland spines on margin or submargin of abdominal segment I. With one microduct on each side of head. Longitudinal line of microducts present submarginally on venter of abdominal segments II-VI, normally with one microduct on each side of each segment. Cicatrices absent.

Notes.

We have been unable to find characters that consistently separate second-instar females of F. japonica and F. pinicola . The swelling of the body adjacent to the abdominal macroducts is usually pointed in F. pinicola and is usually rounded in F. japonica , but we have too few specimens to understand the possible variation in this character.

Second-instar male.

One duct cluster on each side of body, composed of several small ducts and two communal ducts. Three longitudinal lines of microducts on venter of abdomen (one medial and two submarginal). Cluster of small microducts with sclerotized orifice laterad of anterior spiracle absent. Five or more gland spines on each side of body between anterior and posterior spiracles. Antennae each with one enlarged seta.
