Philonthus longicornis Stephens

( Figs. 19 , 45 )

Diagnosis (based on Chani-Posse, 2010). 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).
