Philonthus longicornis may be identified by the eyes about as long as to slightly longer than temples, the antennal segment 2 shorter than preceding segment and antennal segments 4 to 10 elongate, the dorsal rows of pronotum each with five punctures and the paramere shifted toward right margin of median lobe. Length 6.5–7.0 mm. Distribution. Philonthus longicornis is currently considered a cosmopolitan species widely distributed in Central and South America ( Herman 2001 ). Bionomics. Philonthus longicornis has been frequently found in cattle manure in open pastures of North America ( Hu & Frank 1997 ) and Argentina ( Chani-Posse 2004 ), and also cited from other organic debris such as decaying plants, other animal droppings, carcasses, etc ( Smetana 1995 ). This species was also collected from pig carcasses in arid environment of Argentina ( Aballay et al . 2008 , 2012).
