On 30 March 2008, a specimen of the blob sculpin P. phrictus (297 mm LT) was caught off the Guerrero coast, Mexico (17°45&#8242;24&#8243;N, 101°59&#8242;04&#8243;W). The blob sculpin was taken at a depth of 1,100 m within a temperature range of 3.88-4.25 °C, where hypoxic (0.57-0.39 mg/l) conditions prevailed; the specimen was captured over a muddy bottom using a benthic sledge. Representatives of this species had never been reported off the Mexican Pacific coast; our new record extends the known southernmost range by 1,733 km, from 33°19&#8242;N to 17°45&#8242;N for the American coast. Although high variations in morphometric and meristic values are known for the 4 species of the genus Psychrolutes (P. paradoxus, P. phrictus, P. sigalutes, and P. sio) from the eastern Pacific Ocean, a combination of traits and species distribution allow us to identity this specimen as P. phrictus.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen: Psychrolutes phrictus es un pez bentónico de profundidad, que se distribuye en el Pacífico Norte. El 30 de marzo de 2008 se capturó un espécimen del pez gota P. phrictus (297 mm LT) frente a las costas de Guerrero (17°45&#8217;24&#8221; N, 101°59&#8217;04&#8221; W), a una profundidad de 1,100 m, temperatura de 3.88 a 4.25 °C, donde las condiciones de hipoxia prevalecen (0.57-0.39 mg/l); el arrastre se realizó con un patín béntico sobre un fondo fangoso. A la fecha no se había documentado ningún ejemplar de esta especie en las costas de México, por lo que este nuevo registro extiende el intervalo más sureño de distribución 1,733 km de 33°19&#8217; N a 17°45&#8217; N para la costa americana. Aun cuando las variaciones merísticas y morfológicas son grandes en las 4 especies del género Psychrolutes (P. paradoxus, P. phrictus, P. sigalutes y P. sio) en el océano Pacífico oriental, una combinación de caracteres y de su distribución permiten determinar el espécimen en cuestión como P. phrictus.]]></p></abstract>
