Diagnostic description.—
General characteristics as described above; very similar to
S. scutellaris
but distinctly larger. Tegmina surpassing apices of hind
femora
by about 1/5 of their length. Male pronotum with metazona expanded, entirely or almost entirely covering stridulatory apparatus (
Figs. 33
D, 33F). Stridulatory file of male weakly curved,
2.14 mm
long, with 202 (n=1) wide and thin teeth, maximum width of file 141 μm (
Fig. 50
H); teeth of file uniform in thickness, evenly spaced and smoothly narrowing towards proximal end. Male cercus weakly incurved, nearly as thick as long, with large apical spine (
Fig. 38
F); apices of titillators expanded and flattened, with several large teeth (
Fig. 33
G). Ovipositor distinctly curved upwards and clearly widened midlength, slightly longer than half of hind femur (ratio ovipositor/hind femur 0.64-0.75).
Coloration
.— General coloration straw brown to chestnut brown, with wide, dark band extending across the top of the head, pronotum, and posterior edges of tegmina; tegmina with irregularly distributed, small, diffused darker spots; outer pagina of hind femur with distinct reticulate pattern. No green form is known for this species.

Bioacoustics.—
Song unknown.
Distribution —
S. crassicerca
most likely occurs only in the Pacific portion of
Costa Rica
(
Map 17
).
Etymology.—
The specific epithet reflects the shape of the male cercus, which is thicker and stouter than in other members of the genus.
