More on the genera Hadrurus and Hoffmannihadrurus

Michael Soleglad and Victor Fet have recently published a paper with further observations on the genera Hadrurus Thorell, 1876 and Hoffmannihadrurus Fet & Soleglad, 2004 (both Caraboctonidae).

Multiple populations of Hadrurus pinteri from Baja California Sur, Mexico have been examined. It is demonstrated that the southern populations of this species have a larger number of accessory trichobothria (neobothriotaxy) than the northern populations, numbers exceeding the maximum currently recorded for the genus. Examination of carapace and chela coloration and its patterns show a close affinity between H. pinteri and the dark phase of H. concolorous. A new morphometric ratio of the carapace is defined that distinguishes Hadrurus from Hoffmannihadrurus, further supporting the monophyly of the latter genus.
