(Figs. 44–45)
Type material. HOLOTYPE: male (PBI_OON 00016129), Kalimantan (INDONESIA), 1 km N of Camp Pemantus, 45 km W of Sotek [01°12′S 116°12′E; inf.], 23.XII.1980, leg. J. Aoki & H. Harada, deposited at MZT. PARATYPE: 1 male (PBI_OON 00016133), Kalimantan (INDONESIA), Sotek [01°11′S 116°35′E; inf.], 31.XII.1980, leg. J. Aoki & H. Harada, deposited at MZT.
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); paratype very pale.
Distribution. E-Kalimantan, INDONESIA (Fig. 49).
