Philodoria View in CoL sp. A near P. lysimachiella

Figs. 26G View FIGURE 26 , 56H View FIGURE 56 .

Material examined. 6♀, 1 (sex unknown), Halehaku, Ko'olau Gap, Maui, 9.viii.2014 (stored), K. Bustamente leg., 20.7767N, 156.2076W, host: Lysimachia sp., CJ346a–e [CJ346a / SK 753♀ & ♀, CJ346b / 2 ♀, CJ346d / sex unknown (no abdomen)]; deposited in BPBM. Seven specimens were examined, all of which have parts of their body missing. Because specimens are incomplete, we refrain from formally describing this species until a complete specimen becomes available. What remains of seven specimens are: 1 specimen with only 75% of forewing and hindwing remaining, wings without mountant under a coverslip ( CJ346 a / SK753); 5 specimens with only wings and abdomen remaining; sample CJ346d which has wings unmounted and damaged in four separate vials ( CJ346 a– e). The head, antenna, thorax, and legs for all samples were sacrificed for molecular analysis GoogleMaps .

Diagnosis. The forewing pattern is similar to P. lysimachiella ( Fig. 26G View FIGURE 26 ), but Philodoria sp. A is distinguished by a bronze color band ( bb 2) interrupted at middle by an orange patch and female genital characters are differed by the trapezoid lamella antevaginalis rather narrowing at posterior part and shorter cup-shaped antrum and short spines on signa ( Fig. 56H View FIGURE 56 ).

Adult ( Fig. 26G View FIGURE 26 ). See Material examined and diagnosis sections.

Male genitalia. Unknown.

Female genitalia ( Fig. 56H View FIGURE 56 ) (n=1). 1520 µm long. Ostium bursae large; antrum short, cup-shaped; lamella antevaginalis 360 µm, trapezoid, rather narrowing at posterior part, inflexed on the posterior margin. Corpus bursae 700 µm long; paired signa each with a short linear spine.

Distribution. Maui.

Host plants. Primulaceae : Lysimachia sp. This host plant may be a new species discovered by Keahi Bustamente and Hank Oppenheimer (K. Bustamente & H. Oppenheimer pers. comm.)

Biology. Unknown.

Remarks. We observed Philodoria leaf mines on L. remyi in Iao Valley on West Maui ( Fig. 80C, F View FIGURE 80 ). These larvae form white linear mines with a dark brown frass line on the adaxial leaf surface, similar to that of P. molokaiensis . Unfortunately, adults did not emerge from our rearing efforts, and therefore cannot confirm for certain that these were the mines of P. lysimachiella .
