Explanation of Names
Apteromechus texanus Fall 1925
Numbers
4 spp. n. of Mex. (1)
Size
Body is 2.9 to 3.4 mm in length,
1.3 to 1.6 mm in maximum width at mid-length of the elytra. (Riley & King, 2009)
Range
Known Range: Brownsville area of Texas (Cameron County).
Whitehead (1979) suggests that the material cited as "A. ferratus (Say)" by Champion (1906) from Tampico, Mexico (Veracruz) is probably conspecific with A. texanus.
O’Brien and Wibmer (1982) list the range of this species as Arkansas and Texas. The Arkansas record seems unlikely, and the source for this record is not given.
We now have a BG record from ne TX, so the species' range extending to AR seems likely, and as such this sp. should be dropped from TPWD's SGCN list...
Season
Number of compiled Texas collecting events by month:
April (1), May (8), June (3), July (1), August (1), October (1). (Riley & King, 2009)
Remarks
Type Locality: Brownsville, Cameron County, Texas
Texas Parks & Wildlife considers this to be a "Species of Greatest Conservation Need" (SGCN) (2)
