Isohydnocera aegra (Newman, 1840: 364)

(Fig. 37)

Original combination. Hydnocera aegra

Types. A single specimen was collected by Doubleday (Newman, 1840: 364).

Comments. There is a BMNH specimen which reads “? Type ”, but lacks any other distinctive label information (e.g., collector or locality). Another label on this specimen reads “the largest very near Evenus filiformis Spinola t38 f2” indicating a misidentification as a result of the lack of a locality label. The final label reads “ Hemipeplus marginipennis N. Amer. was on this card,” suggesting that perhaps the locality label was allocated to the Mycterid specimen. Searching through the BMNH Mycteridae, I encountered many specimenswith simple, handwritten data such as “Florida” on a small round label or “Fla” typed on a tiny label—collected in the correct timeframe from Florida. However, none read “Ent. Club” or Doubleday, and none appeared as if cut from a shared mount with the aegra specimen. Of course, the Hemipeplus may have been re-mounted, which, under the circumstances, would make matching this aegra to label data impossible. However, the handwritten labels (“ aegra ” and “ Hydnocera aegra Newm. ”) are typical of Newman’s type specimens. As such, the following specimen is here recognized as the holotype.

Series/ Type locality. East Florida.

HOLOTYPE (fixed by monotypy): aegra, Hydnocera aegra Newm,? Type, the largest very near Evenus filiformis Spinola t38 f2 [blue label], Hemipeplus marginipennis N. Amer. was on this card [upside down] (BMNH; 1, the specimen is card mounted, with the abdomen on its own card mount below the specimen).
