Diagnosis

R. bushi is distinguished from other tabellaria group species by a suite of morphological characters, unique DNA sequences, and distinct host fruit association. Morphological characters that diagnose R. bushi are shown in Table 2; wing pattern with subbasal and discal bands separated; anterior apical band reaching wing margin in cell r 4 + 5; the lateral scapular seta is not concolorous with the principle thoracic setae; tarsomere four and five are the same color as the rest of the tarsus; the midtibia does not have a distinct posterodorsal row of setae; in males, the basiphallic vesica is absent; the phallic apodeme is finger-like with a 90° bend anteriorly at the midpoint; the distiphallus has a unique triradiate appendage arising from the tip, whereas in females, the oviscape has two pairs of subapical dorsal setae, and three spermathecae are present, one of which is definitively smaller than the other two. Additionally, DNA sequences from each of the genes used in the present analysis (COI, CAD, period, AATS, or 28S) will distinguish R. bushi from all other Rhagoletis . Within these genes, there are autapomorphic nucleotides that diagnose R. bushi (Supp Table 4 [online only]).
