Greeniella calophylli Williams and Miller   , sp. n.

( Fig. 3 View FIGURE 3 )

Adult female. Body about as long as wide, 0.8–0.9 mm long and 0.8 –1.0 mm wide, reniform, with pygidium projecting posteriorly beyond lobes formed by prepygidial segments of abdomen. Body membranous except for pygidium.

Pygidium with small space between median lobes, without yoke, parallel; apex of each lobe truncate, without notches. Second and third lobes similar in shape and size as median lobes. Without definite gland spines or plates, but with small swelling near marginal apex of macroduct furrows between median and second lobes, and between second and third lobes. Single gland spine on each lateral margin of segment V anterior of third lobes. Single paraphysis on each side of macroduct furrows between median lobes, median and second lobes, and second and third lobes, paraphyses sometimes fused. Macroducts slender, apparently with 2 between median lobes, 3 or 4 between median and second lobes, and 1 or 2 between second and third lobes. Microducts apparently absent. Perivulvar pores absent. Anal opening located in centre of pygidium, anterior of position of vulva.

Prepygidial dorsum with series of gland tubercles on lateral margins of areas forming prepygidial lobes; small microducts present on lateral margins of abdomen anterior of gland tubercles; longer microducts abundant in medial areas of anterior abdominal segments. Prepygidial venter with small microducts near gland tubercles and in submedial areas of anterior abdominal segments. With a few microducts laterad of mouthparts and submedially on posterior thorax.

Antennae with single conspicuous seta, fused with antennal base.

First-instar embryos unusually large, 0.3–0.4 mm long, antennae 5 -segmented, apical segment unusually long; 2 pairs of lobes.

Type material. Holotype adult female. Java, Ujung Kulon, Pulau Peucang 6 ° 45 'S 105 ° 11 'E, 17.ix. 1984, on Calophyllum inophyllum   143 - 1 ( NMV).

Paratypes. Same data as holotype. 5 adult females on 5 slides (4 females containing 1, 2, 3, and 4 embryos respectively) ( BMNH, NMV, USNM).

Notes. Adult females of species of Greeniella Cockerell   are pupillarial with the adult female remaining within the previous (second) instar after the final moult. We have had no access to second-instar nymphs of this species. Greeniella calophylli   is similar to G. javanensis (Green)   and G. mesuae (Green)   in that both have many gland tubercles on the prepygidial lobes, large embryos, and a wide body. Contrasting characters for G. javanensis   and G. m e s u a e are given in parentheses. Greeniella calophylli   differs from G. javanensis   by having 3 pairs of truncate lobes (2 pairs of narrow rounded lobes) and no processes between the lobes (long processes between the lobes). Greeniella calophylli   differs from G. mesuae   by having median lobes of the same size and shape as the second and third lobes (median lobes smaller and with rounded apex) and only a single process between lobes 2 and 3 (3 or 4 processes between lobes 2 and 3).

Etymology. This species is named after the host plant genus Calophyllum   .
