Diagnosis
: The complex anterior gonopods (
Fig. 1
) with a distinctive posterior branch and fimbriate regions separate this species from all others known so far.
Karagama lupus
Shear, 2004
has a basal branch, but it is subequal to the main branch and fimbriate regions are lacking. Also,
T. lupus
has broad paranota on its metazonites.
Karagama loftinae
(
Shear & Krejca, 2011
)
has the posterior branch of the anterior gonopod with a comb-like distal tip.
Etymology
: The species name is a noun in apposition referring to the
type
locality and the late Lady Bird Johnson, former First Lady of the
United States
, who had a deep interest in the preservation of natural areas.

Description
:
Paratype
male from Redwood National Park:
Length, 8.0 mm. 22 ocelli in triangular eyepatch. Metazonites with prominent shoulders on rings 6–25. Coloration pale tan, lightly marked darker brown. Legpairs one and two reduced, three to seven enlarged, basal femoral knobs on legpair four, legpair five basally swollen, otherwise pregonopodal femora not modified. Anterior gonopods (
Figs. 105, 106
,
109
) with main (mesal) branch bearing fimbriae from colpocoxal region near base, additional fimbriate region near tip, ending in short, blunt subapical process set with acute, fine cuticular projections. Posterior gonopods with distinct, band-like sternum, coxae partially fused to prefemora, prefemora with anterobasal, short process bearing few setae; posterior gonopod coxites (
Figs. 107, 108
,
110
) simple, long-triangular, with fimbriate lamellae basally, apically hooked, distal row of blunt teeth on lateral side. Legpair 10 coxae of normal size, with small glands, legpair 11 femora with blunt, dorsally directed knobs.
