Explanation of Names
Microstagetus Wollaston 1861
1 sp. described in our area (M. parvulus Wollaston) from OK(1)
primarily Palaearctic and Afrotropical(2); all images posted here are from southernmost Texas
I have not received a positive ID on this beetle from anyone yet, although Andy Cline suggested it may be Microstagetus. I’ve sent gift material to him and to Mike Thomas. It is very common at one site near Brownsville –the Sabal Palm Grove. It is associated with dead palm fronds and can be found just about everywhere you can find a dead Sabal frond. This species is certainly not "native" to the area. I say this because it is so abundant now, it would have been impossible for the turn-of-the-century Brownsville collectors (Schaeffer, Barber, etc.) to have missed it. The earliest record I have seen for it is 1994. (E.G. Riley, pers. comm., 2010 to MAQ)
our only representative of the primarily Palaearctic and Afrotropical tribe Corylophini that contains one more genus (Corylophus Stephens)(2)
