Anillinus langdoni

Sokolov, Igor M., Sokolova, Yuliya Y. & Carlton, Christopher E., 2007, New species of Anillinus Casey (Carabidae: Trechinae: Bembidiini) from Great Smoky Mountains National Park, U. S. A. and phylogeography of the A. langdoni species group, Zootaxa 1542, pp. 1-20 : 11-12

Key for identification of males of the A. langdoni –species group

This key will allow determination of langdoni – group species in the southern Appalachian Mountains. This area was not covered adequately in the previous key of Sokolov et al. (2004) for this group because the diversity and distributional limits were not fully understood. Non– langdoni -group species can be identified using the earlier key.

1. Both head and pronotum totally covered with polygonal microsculpture................................................... 2

1’. At least head with areas with effaced microsculpture, occupying both frons and vertex OR only frons between frontal furrows, OR with small paramedian patches of effaced microsculpture on each side of the vertex ...................................................................................................................... (other Anillinus species)

2. Beetles from Appalachian Mountains of Tennessee, North Carolina, Virginia, and Maryland .................. 3

2’. Beetles from areas outside Appalachian Mountains (Kentucky, Indiana, Arkansas, Oklahoma) ................. ................................................................................................................................ (other Anillinus species)

3. Smaller: 1.41–1.74mm. Beetles from southern Appalachian Mountains (North Carolina and Tennessee). ............................................................................................................................4 ( langdoni -species group)

3’. Larger: 1.64–1.98mm. Beetles from the middle Appalachian Mountains (Virginia, Maryland) .................. ...............................................................................................................................( virginiae -species group)

4. Males with right paramere short and wide ( Fig. 15 c,18c). Median lobe with enlarged apex and ventral margin ( Fig. 15 a,18a) .................................................................................................................................. 5

4’. Males with right paramere elongated and narrow ( Fig. 16 c,17c). Median lobe with apex and ventral mar-

gin of normal form ( Fig. 16 a,17a) .............................................................................................................. 6 5. Beetles from Burke Co., North Carolina. Walls of median lobe with poriferous canals ( Fig. 18 a). Humeri ( Fig. 6 ), male protarsus ( Fig. 10 ), male profemur ( Fig. 14 ), aedeagus ( Fig. 18 a), spermathecae ( Fig. 22 ), and stylomers ( Fig. 26 ) as illustrated ................................................. Anillinus daggyi Sokolov and Carlton

5’. Beetles from Great Smoky Mountains National Park. Poriferous canals restricted to the apex and ventral margin of median lobe ( Fig. 15 a). Humeri ( Fig. 3 ), male protarsus ( Fig. 7 ), male profemur ( Fig. 11 ), aedeagus ( Fig. 15 a), spermathecae ( Fig. 19 ), stylomers ( Fig. 23 ) as shown ...... Anillinus cieglerae new species

6. Beetles from Swain Co., North Carolina or from south-western parts of Blount Co., Tennessee (west of Thunderhead Mountain). Dorsal sclerites with single, long prolongation basally ( Fig. 16 a). Humeri ( Fig. 4 ), male protarsus ( Fig. 8 ), male profemur ( Fig. 12 ), aedeagus ( Fig. 16 a), spermathecae ( Fig. 20 ), stylomers ( Fig. 24 ) as illustrated .............................................................................. Anillinus pusillus new species

6’. Beetles from Sevier Co. and adjacent parts of Blount Co., Tennessee. Dorsal sclerites with three, approximately equal length prolongations basally ( Fig. 17 a). Humeri ( Fig. 5 ), male protarsus ( Fig. 9 ), male profemur ( Fig. 13 ), aedeagus ( Fig. 17 a), spermathecae ( Fig. 21 ), stylomers ( Fig. 25 ) as illustrated.................... ........................................................................................................ Anillinus langdoni Sokolov and Carlton
