Description

Description of Adult Female Appearance in life: scale cover fairly flat, more or less broadly oval with central or subcentral exuviae. Secreted scale material thin, flexible, mid-brown, blending into color of ripe fruit skin. Exuviae more yellow to reddish brown than secreted material. First instar exuviae surrounded by a raised circle of dark grey secretion, but this sometimes gets rubbed off the scale cover. Adult female beneath scale cover pale creamy yellow; pygidium yellowish brown, darker towards apex. Slide-mounted adult female (Fig. 1) broadly oval, length of holotype1378, range (n= 10): 846–1378, mean 1140.5; maximum width of holotype: 1045; range (n= 10) 649–1078, mean 886.6. Pygidium: Lobes — posterior margin with 3 pairs of well-sclerotized lobes; median lobes (L 1) large, convergent, each hoof-shaped, with inner border short and straight, outer border long and curved with small indentation at base, sometimes with several small teeth along posterior margin. Second lobe (L 2) shorter than L 1, often wider than long, usually with 3 or 4 small teeth along outer margin. Third lobe (L 3) sometimes slightly longer than wide, usually with 2 or 3 teeth along outer margin. Paraphyses —4 pairs of paraphyses present (formula 2 - 2 -0): (1) L 1 with a medium-sized paraphysis (PL 1) with a clubbed inner end originating at anterolateral base; (2) L 2 with a slightly smaller paraphysis (PL 2), similar in shape to PL 1, originating at L 2 anteromesad base; (3) a smaller paraphysis (PL 3) present between L 2 and L 3; and (4) a small paraphysis (PL 4) originating at anteromesad base of L 3. Ventral area anterior to L 1 with large, triangular basal sclerotization arising from mesad half of lobe, longer than wide, longest on mesad margin, laterad margin often rather irregular. Plates — two slender plates present between L 1, each about as long as L 1 (these appear to have pointed apices, often obscured by convergent L 1); 2 plates with fringed apices present between L 1 and L 2 on each side, each slightly longer than L 1, much longer than L 2; 3 plates with fringed apices present between L 2 and L 3 on each side, each plate about 2 to 3 x as long as L 3; plates anterior to L 3 each with a median internal microduct and base wider than an interlobular plate, with a lateral tine on either side of microduct, each tine slightly fringed along the margins. Ducts —11 or 12 pairs of macroducts present on dorsum in submarginal and marginal areas of segments 5 and 6. Anal opening — small, slightly longer than wide (12.2 μm long x 10.6 μm wide in holotype), located about 1.7 x its diameter from anterolateral base of L 1. Perivulvar pores — absent, but sclerotized frame surrounding vulva present, longer than wide.

Prepygidium: dorsum with ducts of 2 sizes; macroducts along dorsolateral margin each about 2 x as long as microducts sometimes present on submargin; abdominal segments 1 – 3 each with 1 – 5 macroducts on each lateral margin. Cephalothorax: each posterior spiracle with 2 microducts situated on medial and lateral sides, and 2 or 3 microducts on ventral lateral margin laterad of the spiracle. Each anterior spiracle with one or two microducts laterad of the spiracle, and about 8 microducts on dorsolateral margin between anterior spiracle and apex of head; pores absent from near spiracles. Setae along margin long and slender with pointed apices. Eyes very small, round and inconspicuous; antennae each bearing 1 conspicuous seta. Specimens examined Type material is deposited at the following institutions: Museo Nacional de Historia Natural, Mexico City, Mexico (MCM); National Museum of Natural History, Washington, D.C., U.S.A. (USNM); California State Collection of Arthropods, Sacramento, California, U.S.A. (CSCA); Florida State Collection of Arthropods, Gainesville, Florida, U.S.A. (FSCA); University of California at Riverside, California, U.S.A. (UCR); and The Natural History Museum, London, U.K. (BMNH). Voucher specimens from the DNA study by Morse et al. (in preparation) have a DNA extraction number given in [square parentheses]. Paratype specimens are mounted individually on slides unless specified otherwise.
