Abstract

The Neotropical assassin bug genus Montina Amyot & Serville, 1843 (Reduviidae: Harpactorinae) is revised for Colombia. Montina has not been adequately explored taxonomically, with its last described species published in 1867. It has ten valid species distributed in tropical areas of Central and South America, but none of them have been formally recorded from Colombia. We describe three new species, M. calarca Mejía-Soto & Forero sp. nov., M. gladiator Mejía-Soto & Forero sp. nov., M. tikuna Mejía-Soto & Forero sp. nov., and report seven species as new records for the country: M. confusa (Stål, 1859), M. distincta (Stål, 1859), M. fumosa (Stål, 1867), M. lobata Stål, 1859, M. ruficornis (Fabricius, 1803), M. scutellaris Stål, 1859, and M. testacea (Stål, 1859). Montina calarca sp. nov. is distinguished by the reddish coloration with black head and legs; densely setose pronotum; connexival margin rounded on segments 4, 5, and 6 without protuberances, connexivum black with a narrow red band on margin; and translucent yellow membrane with hyaline cells and darkened veins. Montina gladiator sp. nov. is distinguished by the red coloration, with black legs, scutellum, and abdomen; connexival margin 4–5 lobed, 6 straight, segments 2–4 with acute posterior process on each segment, connexivum dark brown to black with a narrow red band on its margin. Montina tikuna sp. nov. is distinguished by the reddish-brown coloration, with black scutellum and abdomen; connexival margin nearly straight, segments 2–4 with small posterior acute process, 5–6 with obtuse process, connexivum black; ventral laterotergites only with black scattered erect setae. New characters help delimit Montina and differentiate it from Ploeogaster Amyot & Serville, 1843, its most similar genus. For all species we provide a diagnosis, images, documentation of genitalia, and distribution maps. A key to all the species of Montina is provided.

标题哥伦比亚蒙地纳(半翅目:异翅目:蒙地纳科)的分类订正及三新种描述

新热带刺虫属Montina Amyot&Serville，1843年（红蝇科：Harpactorinae）是为哥伦比亚修订的。蒙蒂纳在分类学上还没有得到充分的探索，其最后一个被描述的物种发表于1867年。它有十个有效的物种分布在中美洲和南美洲的热带地区，但没有一个在哥伦比亚被正式记录下来。我们描述了三个新物种，M.calarca Mejía-Soto&Forero sp.nov.，M.gladiator Mejía Soto&Forero sp.nova.，M.tikuna Mejí的a-Soto和Forero sp.nov.，并报告了七个物种作为该国的新记录：M.confusa（Stål，1859），M.distincta，和M.testacea（Stål，1859）。Montina calarca sp.nov.的特征是红色，头部和腿部为黑色；密被刚毛的原球茎；节段4、5和6上的连接缘圆形，没有突起，连接缘黑色，边缘有一条狭窄的红带；半透明的黄色膜，透明细胞和深色静脉。Montina角斗士sp.nov.的特征是红色，腿、盾和腹部为黑色；连接缘4-5浅裂，6直，节2-4，每个节上有锐后突，连接槽深棕色到黑色，边缘有一条狭窄的红色带。Montina tikuna sp.nov.的特征是红棕色，有黑色的盾和腹部；连接缘近直，2-4节具小的后锐突，5-6节具钝突，连接腔黑色；腹面侧龙涎香只有黑色分散直立刚毛。新的字符有助于界定Montina，并将其与1843年最相似的Ploegaster Amyot&Serville属区分开来。我们为所有物种提供诊断、图像、生殖器文档和分布图。提供了蒙蒂纳所有物种的钥匙。
