Diagnosis.--Key characters: Ommatidial size coarse (Fig. 39b); prosternal process not planar, greatly expanded at apex (Fig. 18) and nearly closing procoxal cavities posteriorly; mesal antennal spines present (although much reduced); pronotum with impunctate regions, without longitudinal rugosities or uniform, large, confluent punctures; femoral carinae absent; procoxal cavities closed laterally (Fig. 24); femoral apices rounded (Fig. 26); tibial carinae absent; shape of spine on antennomere three acute (Fig. 45a, b); femora gradually enlarged (Fig. 37c); antennomere three of males and females about half length of pronotum or less (Fig. 46a); pronotal calli very poorly defined. Length: 10-13 mm.
Distribution and Diversity.--México (Revilla Gigedo Islands). Monotypic.
Discussion.--Nesodes is closely related to the clade including Enaphalodes, Orwellion, Eustromula, Gymnospyra, and Parelaphidion (Figs. 50, 56) based on the implied weighting analysis.
Nesodes strongly resembles Anelaphus and Enaphalodes. It differs from Anelaphus in having the procoxal cavities nearly closed posteriorly (open by about one-half coxal width or more in most specimens of Anelaphus). Nesodes differs from Enaphalodes in having poorly developed pronotal calli (well developed in Enaphalodes) and truncate elytral apices (moderately bispinose in Enaphalodes).
