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 GoogleMaps . 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 GoogleMaps .

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 View FIGURE 44 ); epigastric scutum dorsally without subterminal ridge. The very long and curved postepigastric lateral apodemes (lap) seperate this species from all congeners ( Fig. 44H View FIGURE 44 ).

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 View FIGURE 44 A–C.

CEPHALOTHORAX. Carapace: surface of elevated portion of pars cephalica smooth, sides finely reticulate ( Figs. 44D, F View FIGURE 44 ); 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 View FIGURE 44 ); few scattered non-marginal pars thoracica setae. Eyes: ALE well developed, PLE and PME tiny ( Fig. 44D View FIGURE 44 ); 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 View FIGURE 44 ); posterior margin with broad and short single extension ( Fig. 44E View FIGURE 44 ). 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 View FIGURE 44 ).

ABDOMEN. Cylindrical in dorsal view, rounded posteriorly. Book lung covers (bc) large, ovoid (i.e. sides convex; Fig. 44G View FIGURE 44 ). Epigastric scutum dorsally without subterminal ridge ( Fig. 44G View FIGURE 44 ). Postepigastric scutum long, almost rectangular ( Fig. 44H View FIGURE 44 ), posteriorly directed lateral apodemes (lap) very long, slightly curved, almost reaching posterior margin of postepigastric scutum ( Figs. 44B, H View FIGURE 44 ). Pedicel tube finely ribbed.

GENITALIA. Epigastric region: sperm pore situated at level of anterior spiracles ( Fig. 44H View FIGURE 44 ). 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 View FIGURE 45 A–B). Embolus (em) distal half very narrow, tip spatulate ( Fig. 45B View FIGURE 45 ); embolic spine (esp) with pointed tip ( Fig. 45C View FIGURE 45 ). Conductor (con) with very narrow distal part and pointed tip ( Figs. 45 View FIGURE 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 View FIGURE 49 ).
