This group of eight species was characterised by Schoof (1942: 95) based on "the presence of one femoral tooth, but a second feeble tooth (denticle) is usually present in [C.] cribicollis (Say); relative length of first and second funicular segments of antennae variable; prothorax wider than long, longitudinally carinate or not carinate; mesoscutellum from lateral aspect abruptly declivent basally; elytral intervals 3, 5, 7, 9 acutely costate, feebly convex or flattened; costae, when present, usually complete, intervals never with abrupt elytral elevations; vestiture of recumbent setae, scales or scale-like setae; suberect to erect setae usually present on elytral intervals and sometimes in prothoracic punctures; recumbent setae not condensed in a broad postmedian band; metasternum in males never grooved from meso-to metacoxa; male sometimes with dentiform metaunci; aedeagus with a dorsal membrane (except in [C.] crataegi Walsh), frequently with an apical process and with the transfer apparatus a complex of sclerotised bars.". Of the species from North America north of Mexico, Conotrachelus lobatusis most similar to C. posticatusBoheman, C. cariniferCasey and C. nasoLeConte. These species all have a longitudinal median prothoracic carina (Figs 3b, 4b, 11b); mesosternum with anterolateral angles truncate and prominent. Conotrachelus naso, however, can easily be distinguished from other members of this group by the absence of a profemoral tooth (e.g. presence: Figs 3e, 4b). Size 5.5 mm. Conotrachelus cariniferis distinguished by the presence on the pronotum of cavernous, punctations with raised, thin edges (Fig. 11).  Conotrachelus lobatusresembles C. posticatusin the presence of white to fulvous setae concentrated in a few scattered patches, but mainly in a narrow, posteriorly curved, postmedian elytral band (on the declivity) (Figs 3b, 4b, 7). Male Conotrachelus lobatus, which have elongate fulvous setae ventrally on the fore femur and insertion of antennae subapically on the rostrum (Fig. 3a, c, d), can immediately be distinguished from other male Conotrachelushere treated, by the presence of a well-developed, spatulate metauncus at the distal apex of the hind tibia (Fig. 3e). Conotrachelus lobatusfemales do not posses a spatulate metauncus, instead females have the typical apically narrowing uncus (Figs 4a, b, 7b). Conotrachelus scoparius, instead of a spatulate metauncus, has a fulvous aggregation of elongate setae apically on the hind tibia. Male C. posticatushave a dentiform metauncus and are readily distinguished from other Conotrachelusspecies by having the first and second elytral intervals (interstices) costate anterior to the apical declivity (Fig. 9a, b). On the other hand, female C. posticatushave the first interval costate, yet usually less prominent than in the male, (Figs 7a, 10b). Sexual dimorphism is minimal in C. lobatuscompared to C. posticatus. As in the majority of Conotrachelus, the rostrum in the female is longer, the antennae are located more proximad and the sternum is not concave. Conotrachelusfemales are more challenging than the males to distinguish.  Distribution Mexico BMNH, Entomology, B.
