Table 1 in Small crickets of New Zealand (Orthoptera: Grylloidea: Trigonidiidae and Mogoplistidae), with the description of two new genera and species

Table 1. Genus Bobilla Otte & Alexander, 1983. Summary of morphological differences between adults of the two New Zealand species, Bobilla nigrova (Swan, 1972) and Bobilla bigelowi (Swan, 1972). All abbreviations used here are explained in the Material and methods section. All counts and measurements are median values, followed by minimum and maximum values in brackets. N indicates the sample size.

1 Note the discrepancy between Swan’s and this study’s measurements. After re-measuring Swan’s paratypes (N = 40) I calculated a mean ovipositor length of 5.3 mm in B. nigrova.
