Lineagona chisosi ( Loomis, 1963) new combination

Cleidogona chisosi Loomis, 1963: 121 , figs 5–7 – Shear (1972: 223, figs 288–293).

This species was described by Loomis (1963) from a single male taken at Pulliam Ridge in the Chisos Mountains, Big Bend National Park, Texas. The species has not been collected since. A few errors of observation in the original description were corrected by me in 1972, and I also provided new illustrations. The gonopods are much simpler than those of Lineagona culmenicola , n. sp., in that the lateral (posterior) branch of the angiocoxite is not subdivided and lacks the tiny filaments seen in that species. The male ninth leg telopodites have only four podomeres, the distalmost minute (see Shear (1972: fig 291) The Chisos Mountains at higher altitudes are relatively well-watered and forested, in contrast to the surrounding desert and semidesert terrain.
