We report the range expansion of the Gulf Coast Toad, Incilius valliceps (Wiegmann, 1833), from tropical moist forests to tropical wet forests and towards southeastern Costa Rica. We evaluated erroneous reports of this species in databases on the web. Also, we discussed that movements to areas with wet conditions for a species known from humid and xeric habitats can be explained by the trends in deforestation and increments of the dry conditions during recent decades in the country.

The fossorial snake genus Anomalepis Jan 1860 currently comprises four species with distribution restricted to the Neotropics, occurring from Nicaragua to trans-Andean Peru. Species of Anomalepis occur on the mainland from sea level to about 2,700 m elevation in habitats that range from xerophyte vegetation to tropical wet forests (Kofron 1988; McDiarmid et al. 1999; Uetz et al. 2019; Wallach et al. 2014). Kofron (1988) performed a taxonomic review of the genus Anomalepis, recognizing two phenotypic clusters of species: the A. mexicanus Jan 1860 composed exclusively by its nominal form, and the A. aspinosus Taylor 1939 group consisting of the former species, A. colombia Marx 1953 (Fig. 1) and A. flavapices Peters 1957. While Anomalepis aspinosus occurs in xerophytic formation from 500–2700 above sea level (asl hereafter) along the Peruvian Andes (Kofron 1988; McDiarmid et al. 1999; Wallach et al. 2014), and Anomalepis flavapices is found in the coastal rainforest plains of northwestern Ecuador (Kofron 1988; Wallach et al. 2014), Anomalepis mexicanus presents the most widespread distribution amongst its congeners, occurring in northeastern Honduras, Nicaragua, Costa Rica and Panama from sea level to 725 m altitude. Even though this species has previously been recorded for Peru (Kofron, 1988), it seems unlikely that this specimen belongs to A. mexicanus due to its distinct meristic features (see Kofron 1988) and its outlandish record (see Fig. 2). Marx (1953) described Anomalepis colombia based on a single specimen collected in 1946 by Kjell von Sneidern at La Selva (05º25’23N, 74º57’44W; 1700 m asl), municipality of Pueblo Rico, department of Caldas, Colombia. As far as we know, since its original description, no additional specimen of A. colombia has been reported in literature (cf. Kofron 1988; McDiarmid et al. 1999; Wallach et al. 2014).

Geographic Distributions

Throughout the last century, climate change has altered the geographic distributions of many species. Insects, in particular, vary in their ability to track changing climates, and it is likely that phenology is an important determinant of how well expands can either expand or shift their geographic distributions in response to climate change. Grasshoppers are an ideal group to test this hypothesis, given that co-occurring confamilial, and even congeneric, species can differ in phenology. Here, I tested the hypothesis that early- and late-season species should possess different range expansion potentials, as estimated by habitat suitability from ecological niche models. I used nine different modeling techniques to estimate habitat suitability of six grasshopper species of varying phenology under two climate scenarios for the year 2050. My results support the hypothesis that phenology is an important determinant of range expansion potential. Early-season species might shift northward during the spring, while the modeled geographic distributions of late-season species were generally constant under climate change, likely because they were pre-adapted to hot and dry conditions. Phenology might therefore be a good predictor of how insect distributions might change in the future, and conservation efforts might focus most heavily on early-season species that are most impacted by climate change.
