Etymology.
The species epithet is a noun in apposition and is the general term for a sword with a curved blade. It refers to the species’ very long and curved abdominal apodemes.
Diagnosis.
A. scimitar
sp. nov.
does not belong to the stripe clade and thus shows a completely ornamented sternum. It can be distinguished from other species with a completely ornamented sternum by the combination of the following traits: carapace margin without denticles, sluice reaching from posterior margin to level of coxa I (
Fig. 44D
); epigastric scutum dorsally without subterminal ridge. The very long and curved postepigastric lateral apodemes (lap) seperate this species from all congeners (
Fig. 44H
).
Description.
Description based on
2 males
.
MALE.
With the characters of the genus except as noted. Body length
1.71–1.77 mm
, carapace length
0.75–0.78 mm
. Sclerotized parts uniformly coloured pale orange-yellow, very close to colour 123C ‘yellow ocher’; legs only very slightly paler than body. Habitus:
Figs. 44
A–C.
CEPHALOTHORAX. Carapace: surface of elevated portion of pars cephalica smooth, sides finely reticulate (
Figs. 44D, F
); posterolateral surface without spikes; non-marginal pars cephalica setae not originating from pits; carapace margin with narrow sluice reaching from posterior margin to level of coxa I, without denticles (
Fig. 44D
); few scattered non-marginal pars thoracica setae. Eyes: ALE well developed, PLE and PME tiny (
Fig. 44D
); posterior eye-row straight from above, recurved from front; ALE separated by less than their radius; ALE-PLE separated by less than ALE radius; PME touching for less than half their length; PLE-PME separated by less than PME radius. Sternum completely finely ornamented (
Fig. 44E
); posterior margin with broad and short single extension (
Fig. 44E
). Pleura: surface smooth, presence of pits could not be assessed on stereomicroscope level. Mouthparts: chelicerae anterior face of paturon in lateral view subbasally with strong indention (ind) (
Fig. 44F
).
ABDOMEN. Cylindrical in dorsal view, rounded posteriorly. Book lung covers (bc) large, ovoid (i.e. sides convex;
Fig. 44G
). Epigastric scutum dorsally without subterminal ridge (
Fig. 44G
). Postepigastric scutum long, almost rectangular (
Fig. 44H
), posteriorly directed lateral apodemes (lap) very long, slightly curved, almost reaching posterior margin of postepigastric scutum (
Figs. 44B, H
). Pedicel tube finely ribbed.
GENITALIA. Epigastric region: sperm pore situated at level of anterior spiracles (
Fig. 44H
). Palp: basal segments as well as bulb and cymbium only very slightly lighter in colour than rest of body; bulb stout, only slightly longer than cymbium (
Figs. 45
A–B). Embolus (em) distal half very narrow, tip spatulate (
Fig. 45B
); embolic spine (esp) with pointed tip (
Fig. 45C
). Conductor (con) with very narrow distal part and pointed tip (
Figs. 45
A–B). Embolus-conductor-complex about as long as bulb.
Intraspecific variation.
Body size variable (see above);

very pale.
