Description
Summary:Neblinichthys peniculatus is described from specimens collected in the r&#237;o Carapo (r&#237;o Paragua - r&#237;o Caroni drainage), which drains the southern flank of Cerro Guaiquinima in southeastern Venezuela. Neblinichthys peniculatus differs from all congeners by having mottling on the caudal peduncle consisting of dark spots and dashes (vs. caudal peduncle all about the same color or light below and dark above) and by having spots on the head (spots less conspicuous in nuptial males as the head is darker; vs. no spots). Uniquely among Neblinichthys for which nuptial males are known, the hypertrophied odontodes on the snout are rather short, none as large as the eye diameter.<br>Se describe una nueva especie, Neblinichthys peniculatus, con espec&#237;menes colectados del r&#237;o Carapo (cuenca del r&#237;o Paragua-rio Caron&#237;), que drena el flanco sur del Cerro Guaiquinima en el sureste de Venezuela. Neblinichthys peniculatus difiere de todos sus cong&#233;neres en tener un patr&#243;n de pigmentaci&#243;n moteado en el ped&#250;nculo caudal, que consiste de puntos y l&#237;neas cortas oscuras (vs. ped&#250;nculo caudal m&#225;s o menos uniformemente pigmentado, m&#225;s oscuro dorsalmente y m&#225;s claro ventralmente) y por tener puntos en la cabeza (los puntos son menos conspicuos en los machos nupciales; vs. cabeza sin puntos). Los odontodos hipertrofiados del hocico son cortos en los machos nupciales y ninguno es tan largo como el di&#225;metro del ojo, una condici&#243;n &#250;nica entre las especies de Neblinichthys de las cuales se conocen los machos nupciales.
