Kampimodromus, Nesbitt, 1951

Notes on the identification key for the genus Kampimodromus View in CoL View at ENA

The identification key provided in this study for 16 species of Kampimodromus is based on the previous key by Döker et al. (2017). However, in the present study, we resurrected K. adrianae to valid species status and included it in the key due to the distinct differences in its dorsal setal length especially for dorsocentral setae and serrations on j4, j5, j6, J2, Z5, Z1 and S5. Tixier et al. (2006) suspected that K. adrianae is a junior synonym of K. hmiminai McMurtry and Bounfour, 1989 based on COI sequences from populations collected from Salix canariensis Chr. Sm. ex Link ( Salicaceae ) in the Canary Islands and Ficus carica L. ( Moraceae ) in Meknes, Morocco. The same authors stated that the genetic distance between these two species was similar to the distance between two populations of K. aberrans which were collected from Celtis australis L. ( Ulmaceae ) and Quercus pubescens Willd. ( Fagaceae ) in Montpellier, France. However, Döker et al. (2018) used four species of Kampimodromus to construct a phylogenetic tree based on their ITS sequences and the sequences available in the GenBank database. The phylogenetic tree of Döker et al. (2018) showed that the sequence, HQ404798 View Materials , deposited as K. aberrans , originating from a population collected from C. australis in Montpellier, France is identical to K. corylosus . Therefore, at least one of the two K. aberrans populations identified by Tixier et al. (2006) is likely to be K. corylosus . This situation appears to negate the argument of Tixier et al. (2006) that the genetic difference between K. hmiminai and K. adrianae is the same as that between two populations of K. aberrans . In that light, we propose the reinstatement of K. adrianae as a valid species due to the distinct differences in its dorsal setal lengths, until more accurate morphological and molecular studies, and possibly cross-breeding experiments, are conducted.
