Abstract
Plant bugs, species of Miridae (Heteroptera), are not well known in the Neotropics, and Colombia is not an exception. Based on data from the available systematic catalog (Schuh 2002–2013) fewer than 150 species are recorded from the country, clearly an underestimation. Recent fieldwork has resulted in several new interesting taxa from Colombia. Carvalhomiris Maldonado & Ferreira, 1971, contains three described species from Colombia and Ecuador. From specimens collected in Jardín, Antioquia, Carvalhomirishenryisp. n. is described. Images of the dorsal habitus and the male and female genitalia are provided. Based on morphological examination of the new species and published information, morphological characters were coded to construct a phylogenetic matrix for a cladistic analysis in which the phylogenetic position of the new species is assessed. Carvalhomirishenryisp. n. is the northernmost species of the genus and noteworthy because it is the first record of any species of the genus in the Western Cordillera: all other species are known from the eastern flank of the Andes (Ecuador) or the Eastern Cordillera (Colombia). Natural history observations of the new species, including associations with composites (Asteraceae) are provided. It is speculated that the mirid might be predacious.
Highlights
Miridae are the most diversified family of Heteroptera with more than 11,000 described species (Ferreira et al 2015, Wheeler and Krimmel 2015, Henry 2017)
Species of Carvalhomiris are rather homogeneous in external morphology, but their male genitalia are distinct (Forero 2009)
Carvalhomiris henryi sp. n. is more closely related to C. brachypterus and C. truncatus, than to C. bifurcatus based on characters of the male and female genitalia
Summary
Miridae are the most diversified family of Heteroptera with more than 11,000 described species (Ferreira et al 2015, Wheeler and Krimmel 2015, Henry 2017). In the Neotropics, taxonomic efforts to reveal the family’s diversity were carried out most notably by José Candido de Melo Carvalho and colleagues (Carvalho and Froeschner 1987, 1990, 1994, Henry and Wheeler 1995). The Orthotylinae comprise six tribes (Schuh 2002–2013), one of which is the paraphyletic Orthotylini (Cassis and Schuh 2012). Within this tribe, Schuh (1974) recognized several informal generic groupings, one of which is the Zanchius group, which includes Carvalhomiris Maldonado & Ferreira, 1971 (Forero 2009). The generic composition of the Zanchius group has varied through time (Schuh 1974, Henry 1995, Forero 2009), but a phylogenetic analysis for the group is not yet available
