Etymology.
The name refers to the
type
locality.
Diagnosis.
The epigynum with an overhanging projection resembling a human epiglottis is distinctive. This is also the smallest
Lapsias
known.
Notes.
This species is placed provisionally in
Lapsias
, as its body form is unremarkable (like
Lapsias
) and there is no other genus where it is more justified. Phylogenetic studies may very well revise its placement.
Description.
Female
(
holotype
). Carapace length 1.3; abdomen length 1.5. Carapace relatively square, high. PME small. Chelicerae with 2–3 promarginal and 2 retromarginal teeth. Palp with tarsal claw. Tibia of first leg with 3 pairs of ventral macrosetae; first metatarsus with 3 pairs. Epigynum (
Fig. 24
) with a central depression, over which is an epiglottis-shaped projection. Colour (
Figs 21–23
): Dark brown; abdomen with faint chevrons.
Natural history.
The one specimen was collected from a small patch of moist forest. The forest was somewhat disturbed — less than
10 m
from where the specimen was found was a highway; on the other side was a river within
50 m
.
Although the exact location and microhabitat where the specimen was found is not known, the primary microhabitats searched were leaf litter and mossy tree trunks. When walking, the second pair of legs are waved periodically, as seen in
Thrandina
and many other basal salticids (Maddison, 2006, 2009). A video of the living
holotype
is available at http://www.youtube.com/watch?v=eGfizPH1LoU.
