Fontaria oblonga C. L. Koch 1847: 175 ; 1863: 73–74, pl. 32, fig. 64a, b. Attems 1899: 11, 151; 1938: 167. Chamberlin and Hoffman 1958: 55.

Nannaria oblonga: Hoffman 1999: 367 . Marek et al. 2014: 37.

Type specimen. Male holotype ( ZMHB) taken by unknown collector on an unknown date prior to 1847 at an unknown location in Pennsylvania.

Remarks. As with those that Shelley (2014) published of the rhinocricid spirobolidan, Spirobolus monilicornis Porat 1876 , fig. 24 is an unpublished sketch of the holotype gonopod that Dr. Hoffman made while visiting the ZMHB decades ago. The prefemoral process is substantially shorter than the acropodite and leans toward it, and a basal spur is not apparent in this view. We have not encountered this form in either the field or preserved holdings and cannot suggest a region of Pennsylvania where it may occur. All males from this state and New York that we have seen or have been illustrated possess substantially longer prefemoral processes relative to their acropodites. The proportional disparity seems significant, so we hesitate to assign samples to N. oblonga or propose new synonymies, and publish Dr. Hoffman’s sketch to benefit future workers.
