Calophya praestigiator Burckhardt sp. nov.

( Figs. 31, 33, 35 )

DESCRIPTION

Adult. As C. terebinthifolii .

Fifh instar immature ( Fig. 31 ). Coloration. Dorsal surface of body yellow to ochreous. Antenna greyish brown. Membranes yellowish. Ventral body surface and legs white to light yellow.Tip of rostrum black.

Structure. Body ( Fig. 31 ) almost circular, 1.04 to 1.07 as long as wide. Anterior margin of head forming 2 relatively flat lobes ( Fig. 33 ). Antenna ( Fig. 33 ) 1-segmented, with large, irregularly subrectangular base and digitiform apex; bearing 4 diamond-shaped setae along antero-median margin as well as 3 rhinaria and 1 diamond-shaped seta along antero-lateral margin. Tarsi with each 1 small claw about as long as arolium which is almost circular and 1 claw which is reduced to a short spine ( Fig. 35 ). Forewing pad 0.71 to 0.72 times as long as body; anterior margin of humeral lobe ending distal to anterior eye margin, subacute. Abdominal dorsum without median row of horns. Caudal plate length to width ratio 0.42 to 0.44. Circumanal ring near posterior abdominal margin, oval, consisting of a single row of oval pores; on each side of circumanal ring with 1 very long simple seta and with a pair of short normal setae between posterior margins of circumanal ring and caudal plate. Marginal setae as follows (1 side only): head ( Fig. 33 ) with 10 to 13 (11.75 ± 1.26) densely spaced short diamond-shaped setae, forewing pad ( Fig. 31 ) with small, widely spaced lanceolate setae, and caudal plate ( Fig. 31 ) with 32 to 36 (34.25 ± 1.71) densely spaced short diamond-shaped setae.

Measurements in mm: range (mean ± standard deviation) (2 immatures). Body length 0.87, antenna length 0.14, forewing pad length 0.62 to 0.63 (0.62 ± 0.01), caudal plate length 0.22 to 0.29 (0.26 ± 0.04).

ETYMOLOGY

From Latin praestigiator = impostor, cheat, deceiver, referring to the close morphological resemblance to C. terebinthifolii .

COMMENTS

Adults of C. praestigiator are almost identical to those of C. terebinthifolii ( Fig. 7 ) and no stable characters could be found to separate them. They differ from C. latiforceps and C. lutea , whose body color is yellow ( Figs. 6, 8 ), in the dark head and thorax (see key).

The immatures of C. praestigiator ( Fig. 31 ) differ in their entirely yellow body from those of C. therebinthifolii ( Fig. 32 ) which bear 2 dark obliquely longitudinal submedian stripes and a dark abdominal tip. The fore margin of the head forms relatively flattened lobes in the former ( Fig. 33 ) and more arcuate lobes in the latter ( Fig. 34 ). The outer basal part of the antenna is small and more rectangular bearing a thick lanceolate seta in the former ( Fig. 33 ), and larger and subtrapezoidal bearing a slender lanceolate seta in the latter ( Fig. 34 ). The number of marginal diamond-shaped setae on the caudal plate (1 side only) ranges in C. praestigiator from 32 to 36 (34.25 ± 1.71) and in C. terebinthifolii from 40 to 43 (41.00 ± 1.41). Immature C. praestigiator differ from C. latiforceps with which they share the lack of a dark color pattern in the longer apical process of the antenna ( Fig. 34 versus Fig. 29 ) and the smaller number of marginal lanceolate setae on the caudal plate: C. praestigiator 32 to 36 (34.25 ± 1.71), C. latiforceps 40 to 44 (41.75 ± 1.71). Calophya praestigiator and C. terebinthifolii immatures share the presence of a seta on the outer side of the antenna, which is lacking in C. latiforceps and C. lutea , the presence of marginal lanceolate setae on the wing pads in the former species pair which are inconspicuous and rod shaped in the latter, as well as only 1 fully developed claw rather than both claws equally developed as in the latter species pair. Calophya praestigiator differs from the other pit gall inducing Calophya species associated with Schinus as indicated in the key below.
