Etymology.
The specific name refers to the
type
locality. It is to be treated as a noun in apposition.
Diagnosis.
This species resembles
C. orellana
sp. nov.
and
C. pocone
sp. nov.
; males can be distinguished from the both above cited species by the longer epigastric apodems extending posteriorly to the spiracles (
Figs 103B
,
106B
,
110B
); females can be distinguished from both species above by the shape of the internal genitalia with reduced sclerotized wall and chitinized wall areas and a proportionally narrower anterior stalk-like projection (
Figs 105H
,
109H
,
112H
).
Description. Male
(
PBI
_OON 25611). Total length: 1.04. CEPHALOTHORAX:
Carapace
pale orange, broadly oval in dorsal view, pars cephalica slightly elevated in lateral view, surface of elevated portion of pars cephalica smooth, sides smooth; lateral margin without denticles.
Clypeus
straight in front view, high, ALE separated from edge of carapace by their radius or more, around ALE diameter.
Eyes
all subequal; ALE separated by more than their diameter, PLE-PME separated by less than PME radius.
Sternum
pale orange, fused to carapace, furrow smooth, surface smooth, microsculpture absent, anterior margin with continuous transverse groove, posterior margin not extending posteriorly of coxae IV, groove at anterior margin shallow; setae originating from surface.
Mouthparts:
Chelicerae, endites and labium pale orange. Chelicerae anterior face unmodified; retromargin without teeth; fangs without tooth-like projections; paturon inner margin with short inter-digitating setae, laminate groove absent. Labium anterior margin indented at middle. Endites anteromedian part forming a groove between serrula and the apical portion. ABDOMEN: rounded posteriorly; dorsum soft portions pale white. Book lung covers slightly elevated. Pedicel scuto-pedicel region unmodified, plumose setae absent. Dorsal scutum pale orange, middle surface smooth, sides smooth. Epigastric scutum anterior spiracles secondary openings at level of epigastric furrow in an indent. Postepigastric scutum pale orange, almost semicircular, fused to epigastric scutum, with long posteriorly directed lateral apodemes. Spinneret scutum narrow. Dorsum setae sparse.
Distribution.
Abdomen setae dorsal seta very sparse. LEGS: pale orange. GENITALIA: Epigastric region with sperm pore oval, situated at level of anterior spiracles, rebordered. Palp proximal segments pale orange. Conductor flattened laterally, with narrow and curved dorso-distal tip (
Fig. 103F
); embolar tip a translucent tube with narrow embolar distal process; embolar prolateral process narrow, with narrow translucent dorsal area (
Figs 103G
̅H, 104A̅D).
Female
(
PBI
_OON 25656). As in male except as noted. Total length: 1.15. GENITALIA: internal genitalia central portion triangular, lateral apodemes elliptic narrowing towards distal end, sclerotized wall area triangular, receptaculum cavity reduced (
Fig. 105H
).
