Diplolepis tecturnarum (Kinsey)

Andricus tecturnarum Kinsey [Per the recent 2023 publication re-establishing the genus Feron, all reports of F. tecturnarum from the United States are very likely to actually refer to the new species F. tetyanae, and F. tecturnarum is only known from Mexico presently]

This species was described from an unknown oak from San Luis Potosi, Mexico. The writer found the galls very abundant on Q. undulata at Tijeras, N. Mex., in April, 1918, and again on November 1, 1921 (adults emerging by hundreds February 20 to March 9, 1922). Galls on this oak were seen also in Blue Canyon and Nogal Canyon near Socorro, at Hillsboro and Kingston, in the Burro Mountains and in Arizona at Hackberry and Ashfork (flies emerg- ing February 14). The galls were also very common on Q. grisea at Magdalena, N. Mex., in November, 1921, the flies emerging in large numbers February 20 to March 8. Galls were seen at Williams, Ariz., also. One cluster of the galls was collected on Q. gambelii near Magdalena, flies emerging February 4r-20. At Oracle, Ariz., a few galls occurred on Q. arizonica, adults emerging March 9. Here the galls are hard to distinguish from nubila when seen up in the tree, but in hand the difference in structure is at once apparent. At Las Vegas Hot Springs galls on an unknown oak contained pupae on October 12 and adults emerged January 13, February 20, and March 8. At Shoemaker, Rowe, Glorieta, Tijeras, and Magdalena galls were seen on what may have been Q. fendleri. The galls were also seen at Fierro and in Arizona in the Huachuca and Patagonia Mountains and about Prescott.
