Figure 11 from: Shiraiwa K, Cong Q, Grishin NV (2014) A new Heraclides swallowtail (Lepidoptera, Papilionidae) from North America is recognized by the pattern on its neck. ZooKeys 468: 85-135. https://doi.org/10.3897/zookeys.468.8565

Figure 11 - Neck pattern, male genitalia, and morphometrics. a–d Heraclides rumiko, paratype, Mexico: Baja California Sur: Buena Vista, 1-Oct-1981, leg. D. Faulkner & F. Andrews, genitalia KS017 [SDMC] A–D Heraclides cresphontes, USA: Georgia: Clark Co. July 2009, genitalia KS009 E Morphometric measurements performed on genitalia and facies and plotted in two dimensions. Horizontal axis is a weighted average of the three genitalic measures: 0.6*"U-B Angle" + 0.2* (B−A)/(C−B) + 0.2*G/H. "U-B Angle" is measured in radians. Vertical axis is a weighted average of the four facies measures: 0.15*"YL" + 0.4*F/P + 0.4*T/V + 0.05 W/D, where "YL" is equal to 0 or 1, if yellow line on the neck is separated into spots or continuous, respectively. Measured distances are indicated on the illustrations. Each of the two (genitalic and facies) linear combinations of measures completely segregates Heraclides rumiko (red points) from Heraclides cresphontes (blue points) specimens (not from central Texas) with a hiatus. Even a single measure "U-B Angle" identifies all specimens correctly, except #12, which has a brachium strongly curved dorsad. Specimen localities: Heraclides cresphontes: 1. GA: Clark Co.; 2.

Central Texas specimens are from Bexar (33–38, 42–48), Williamson (39–41), Travis (31, 32), Bastrop (30), and Brazos (29) Counties. Voucher codes for these specimens are: 29. NVG-2236; 30. -2299; 31. -2300; 32. -2174; 33. -2192; 34. -2196; 35. -2205; 36. -2209; 37. -2210; 38. -2216; 39. -2301; 40. -2225; 41. -2229; 42. -2191; 43. -2197; 44. -2204; 45. -2208; 46. -2211; 47. -2215; 48. -2218. Species (color on the plot) is assigned to central Texas specimens by COI barcode. See Supplementary Table 1 for more data. Specimens 36 and 41 are apparent hybrids or the results of introgression.
