Herina caribbeana Kameneva, sp. n. from Dominica is described and figured. It is related to the narytia group of species, to date represented by 4 North American species, but differs from these by the wing pattern (dark spots at apex of R1 and on the crossbands r-m and dm-cu separated, not forming crossband), as well as male genitalia (prensisetae long and close together). This is the first record of the genus Herina Robineau-Desvoidy, 1830 from the Neotropical Region. A key to the New World species is provided.
Herina arjunae Kameneva, sp. n. from mountain grasslands on volcano Arjuna (at 2000 m a. s. l.) is described and figured. It is closely related to H. orientalis (Schiner, 1868) in the very similar position of crossveins on the wing, structure of female aculeus and spermathecae, but differing by its well-developed wing pattern with brown subbasal and apical bands, and with crossvein dm-cu brown emarginated (lacking in H. orientalis). Diagnosis and key to species of Herina orientalis group are provided.
A preliminary list of the picture-winged flies known from Columbia is supplemented by 15 species based predominantly on the materials from the National Museum of Natural History, Washington, D.C., USA and now contains 28 species, including Xycores igniceps gen. & sp. n. from Venezuela and Colombia. The new genus belongs to the subfamily Otitinae and is preliminarily assigned to the tribe Cephaliini by the combination of the high clypeus, strongly widened palp, setulose vein R1, and ejaculator with short sperm pump and long fan-like apodeme. It clearly differs from other members of the tribe by the combination of elongate, narrow, apically truncated flagellomere 1, robust, mainly shining thorax with pair of microtrichose vittae, well developed proepisternal, postpronotal, acrostichal, 2 pairs of dorsocentral and scutellar setae, wing with entirely setulose vein R1 abdominal tergites devoid of microtrichia, sternites and abdominal pleura narrow, male genitalia with short epandrium, numerous (7–8) prensisetae arranged into a row along posterior margin, shallow hypandrium with pair of setulose pregonites, no postgonites or epiphallus, and an almost bare phallus with a pair of long spines submedially.
