Etymology
. The specific name is the Spanish form of the word scimitar, a
type
of sword used by several eastern peoples, especially by Muslim warriors, alluding to the shape of the RTA.
Diagnosis
. Males of
Syspira cimitarra
are easily distinguished from other Dominican species by the shape of the retrolateral tibial apophysis elongated and curved at tip, and by the filiform apical projection of the embolar base (
Figs 1A −B
,
2B −F
). Females resemble those of
Syspira jimmyi
sp.nov.
by the enlarged atrium, but can be distinguished by the larger epigynal plate with moderately projected anterior margins of posterior plates, and longer copulatory ducts (
Figs 1C −D
,
2I
).
Description
.
Male
(
Holotype
). Coloration: carapace orange with two dark grey paramedian bands, spanning from anterior border to posterior border of carapace. Chelicerae red brown with median frontal black narrow stripe. Labium, endites, sternum and venter of coxae yellowish. Legs orange with metatarsus and tarsus dark orange. Abdomen gray with two longitudinal dorsal rows of white spots. Total length 9.3, carapace length 4.2, width 3.3. Eye diameters: AME 0.16, ALE 0.16, PME 0.21, PLE 0.21. Chelicerae 1.6 long, with 3 promarginal and 2 retromarginal teeth (

). Leg measurements: femur I—3.8; II—3.7; III—3.5; IV—4.5. Leg spination: I—tibia
