Geotrupes (Onthotrupes) pecki Howden, 1974   Figs 6, 9 a–b, 10b

Geotrupes pecki   : Howden (1974: 572, Plate II), Trotta-Moreu et al. (2008: 43, 47, 50, 51), Trotta-Moreu and Lobo (2010: 46).

Remarks.

This species has been recorded only once in the literature, more than 40 years ago, when Howden described it in 1974 in the Sierra Sur (Sierra de Miahuatlán). Using the only two known distribution records reported by Howden (1974), Trotta-Moreu et al. (2008) performed an analysis of the known and potential distribution of G. pecki   in the state of Oaxaca using the MaxEnt prediction model ( Phillips et al. 2006). For G. pecki   , Trotta-Moreu et al. (2008) estimated a potential distribution area of 5254 km2 and mean values for altitude (1862 m), rainfall (1524 ± 287 mm), and temperature (18.5 ± 5 °C). With the present collecting localities, we can recalculate and correct the Trotta-Moreu et al. (2008) too low mean value for altitude for this species.

Below, an updated key for the genus Geotrupes   in Oaxaca is presented. G. truncaticornis   Howden is not included in the key; because it is known only from Guerrero. Trotta-Moreu et al. (2008) erroneously reported it from Oaxaca (Kohlmann in press).
