“…Such a placement is also indicated when using Anderson's (2002) key to the North American genera of Entiminae. Nevertheless, our knowledge of the phylogenetic limits of these tribes is judged too incomplete and the available character support too weak to warrant a tribal reallocation of Apotomoderes at this time (see also Marvaldi 1997;Franz 2010;Franz and Girón 2009). Likewise, the herein presented phylogeny should not be interpreted as a strong hypothesis about the relationships among the outgroup taxa.…”

Th e weevil genus Apotomoderes Dejean, 1834 (Curculionidae: Entiminae: Geonemini) is revised, including a redescription of the only previously known species, A. lateralis (Gyllenhal, 1834), and descriptions of fi ve new species: A. anodontos sp. n., A. menocrater sp. n., A. sotomayorae sp. n., A. chariedris sp. n., and A. hadroprion sp. n. Th e monophyly of Apotomoderes is supported by multiple synapomorphic character states including the two-segmented labial palps, a postocular constriction on the head, a sexually dimorphic, globular pronotum in males, and the presence of setae in the dorsal subapical region of the aedeagus. In addition, all species of Apotomoderes except A. anodontos have a large, knife-like cuticular tooth on the profemur and a toothed ridge along the anteromesal margin of the protibia. Illustrations of external and internal morphological traits are provided, along with a key to the six constituent species. A cladistic analysis of 12 taxa (6 outgroup, 6 ingroup) and 22 characters yielded a single most parsimonious cladogram (L=33, CI=75, RI=90) with the topology (A. anodontos, (A. menocrater, (A. sotomayorae, (A. lateralis, (A. chariedris, A. hadroprion))))). A species of Artipus Sahlberg (Naupactini) was placed as the most immediate relative of Apotomoderes; however, the state of phylogenetic knowledge of Caribbean entimine weevil is still too incomplete to warrant any higher level rearrangements. All species of Apotomoderes occur on Hispaniola with the exception of A. sotomayorae which is endemic to Mona Island, Puerto Rico. A historical biogeographic reconstruction yielded the taxon-area cladogram (southwestern Dominican Republic, (eastern Dominican Republic, Mona Island)), suggesting two successive eastbound colonization events in the Miocene/Pliocene, originating from the southern Hispaniola peninsula. Reliable host plant records are unavailable although adults of A. menocrater have been found on allspice (Pimenta Lindley; Myrtaceae) and lignum vitae (Guaiacum Linnaeus; Zygophyllaceae).

“…Although the taxonomic novelty of these inclusions had been recognized by systematists for nearly ten years, the challenge of placing them confidently into existing classifications has precluded their formal naming and description (Steven R. Davis and Michael S. Engel, personal communication). This circumstance has changed after the publication of revisionary and phylogenetic treatments, including Franz and Girón 2009, Franz 2010a, Girón and Franz 2012, Zhang et al 2017, and an unpublished, multi-locus molecular phylogenetic analysis of Neotropical entimine weevils with nearly 250 terminals (in preparation). In particular, novel integration of the amber-preserved specimens with the morphological cladistic analysis of reveals their genus-level identity and uniqueness in relation to the therein recognized extant lineages and terminals.…”

“…The description of Scelianoma compacta [FZ2017] from Hispaniola is indicative of a more widespread historical range of Scelianoma [FZ2017] than reflected in the extant, southwestern Puerto Rican Scelianoma elydimorpha Franz and Girón 2009 sec. Franz and Girón (2009). The presence of Diaprepes anticus [FZ2017] in Hispaniola during the Early Miocene suggests an eastward directed process of island colonization and likely speciation of members of Diaprepes [FZ2017], given that most extant relatives occur throughout the Lesser Antilles.…”

BackgroundUsing syntactic and semantic conventions of the taxonomic concept approach (Franz et al. 2015), we describe three newly recognized fossil broad-nosed weevils (Coleoptera: Curculionidae: Entiminae) preserved in Early Miocene amber (ca. 20.4-16.0 mya) from the Dominican Republic: Scelianoma compacta sp. n. sec. Franz & Zhang (2017) (henceforth abbreviated as [FZ2017]), Tropirhinus palpebratus sp. n. [FZ2017], and Diaprepes anticus sp. n. [FZ2017]. The taxonomic assignment of the amber inclusions is grounded in a preceding phylogenetic analysis by Franz (2012). As many as 88 of the 143 therein identified characters were coded for the fossils, whose traits are largely congruent with those present in extant congeners while also differing in ways that justify their new nomenclatural and taxonomic status.New informationWe present detailed images, descriptions, and phylogenetically informed diagnoses for the three new species-level entities, along with logically consistent Region Connection Calculus (RCC-5) alignments of the amended genus-level classifications for Scelianoma Franz and Girón 2009 [FZ2017], Tropirhinus Schoenherr 1823 [FZ2017], and Diaprepes Schoenherr 1823 [FZ2017] - in relation to 2-4 preceding classifications published in 1982-2012. The description of Scelianoma compacta [FZ2017] from Hispaniola is indicative of a more widespread historical range of Scelianoma [FZ2017] than reflected in the extant, southwestern Puerto Rican Scelianoma elydimorpha Franz and Girón 2009 sec. Franz and Girón (2009). The presence of Diaprepes anticus [FZ2017] in Hispaniola during the Early Miocene suggests an eastward directed process of island colonization and likely speciation of members of Diaprepes [FZ2017], given that most extant relatives occur throughout the Lesser Antilles. The herein presented data will facilitate more reliable reconstructions of historical biographic processes thought to have played a prominent role in the diversification of the West Indian and Neotropical mainland broad-nosed weevil lineages.

The genus Lachnopus Schoenherr (Coleoptera : Curculionidae : Entiminae : Geonemini Gistel), with 66 species described to date, is the largest and most widespread entimine weevil genus in the Caribbean region. The monophyly and internal phylogenetic composition of Lachnopus are tested, using a cladistic analysis of 61 adult morphological characters of 31 ingroup species and five outgroup taxa representing the genera Diaprepes Schoenherr, Exophthalmus Schoenherr, Pachnaeus Schoenherr (all Eustylini), Ischionoplus Chevrolat (Geonemini) and Apodrosus Marshall (Polydrusini). The analysis produced two most parsimonious cladograms with a length of 167 steps, a consistency index of 36 and a retention index of 73. According to the strict consensus and preferred character state optimisations, the examined species of Lachnopus do not form a monophyletic entity, even though most species are placed in a major L. coffeae–L. guerinii ingroup clade, which stands in sister relationship to Ischionoplus. This major clade is constituted by at least three well-recognisable subgroups, each associated with a particular geographic range in the Caribbean region: (1) a widely distributed L. coffeae–L. lineicollis ‘grade’; (2) the Hispaniolan L. proteus–L. mercator clade; (3) and the L. hispidus–L. guerinii clade with species from Cuba, Florida and Jamaica. This study provides a sound phylogenetic basis for future revisions of Lachnopus and related geonemine genera.
