Etymology. The species epithet is dedicated to Dr. Myles H. M. Menz (*1982), an Australian zoologist, botanist and conservation biologist whose friendship and scientific work is highly admired by the first author.
Diagnosis. A. menzi sp. nov. belongs to the stripe-clade and can be distinguished from other species of this clade by the combination of the following traits: carapace without spikes; carapace margin with blunt denticles, sluice (slu) restricted to posterior margin ( Fig. 28D View FIGURE 28 ); epigastric scutum in females posterolaterally with a row of longitudinal ridges (lr) ( Fig. 31F View FIGURE 31 ). It is the only species of the stripe-clade showing a completely smooth carapace surface ( Figs. 28D, H View FIGURE 28 ).
Description. Description based on 9 males and 4 females.
MALE. With the characters of the genus except as noted. Body length 1.27–1.38 mm (n=9), carapace length 0.61–0.65 mm (n=9). Sclerotized parts uniformly coloured orange-brown, close to colour 340 ‘robin rufous’; legs slightly paler than body, pale orange. Habitus: Figs. 28 View FIGURE 28 A–C.
CEPHALOTHORAX. Carapace: entire surface smooth ( Figs. 28 View FIGURE 28 A–D, H); posterolateral surface without spikes; posterior edge of pars cephalica with slightly stronger modified hair bases, appearing as small denticles ( Fig. 28D View FIGURE 28 ); carapace margin with sluice (slu) restricted to posterior margin, with blunt denticles ( Fig. 28D View FIGURE 28 ). Eyes: posterior eye-row straigth from above, procurved from front; ALE largest, separated by their radius to diameter; ALE-PLE separated by less than ALE radius; PME touching throughout most of their length; PLE-PME separated by less than PME radius. Sternum coarsely ornamented except rather broad smooth median stripe ( Figs. 28 View FIGURE 28 E–G); posterior margin with broad single extension, covered with blunt denticles ( Figs. 28 View FIGURE 28 E–G); setae appearing slightly plumose at SEM level ( Fig. 29A View FIGURE 29 ). Pleura: surface smooth with pairs of large pits dorsally of each coxa I, II and III (as in A. brunomanseri sp. nov., cf fig. 10B). Mouthparts: chelicerae posterior margin of inner surface proximally modified to a ridge with median slit, covering about 2/3 of margin length, distally ending in a rounded ‘knob’ ( Fig. 29D View FIGURE 29 ); promargin with row of flattened setae (rfs) in combination with plumose setae ( Figs. 29 View FIGURE 29 D–E), distally extending into a short inwards pointing tooth-like projection (tlp) ( Figs. 28H View FIGURE 28 , 29D View FIGURE 29 ); anterior face of paturon in lateral view subbasally with slight indention (ind) ( Fig. 28C View FIGURE 28 ). Endites distally with brush of special wing-like setae (ws) on inner margin ( Figs. 29 View FIGURE 29 B–C), outer margin subdistally with a pair of rather long inward bent plumose setae (ebs) ( Fig. 29B View FIGURE 29 ).
ABDOMEN. Book lung covers (bc) large, elliptical to dumbbell or pear-shaped (sides slightly concave), about 3–4 times longer than wide ( Fig. 29F View FIGURE 29 ). Epigastric scutum dorsally with widely oval subterminal ridge (sr) ( Fig. 29F View FIGURE 29 ). Postepigastric scutum long, semicircular, with long posteriorly directed lateral apodemes (lap) ( Fig. 29G View FIGURE 29 ). Setae appearing slightly plumose at SEM level.
GENITALIA. Epigastric region: sperm pore situated between anterior and posterior spiracles ( Fig. 29G View FIGURE 29 ). Palp: basal segments lighter in colour than rest of body; bulb rather stout, tapering apically ( Figs. 31 View FIGURE 31 A–D). Embolus (em) tip spatulate ( Figs. 31C, E View FIGURE 31 ); embolic spine (esp) with fringed tip ( Fig. 31E View FIGURE 31 ). Conductor (con) with slender tip ( Figs. 31C, E View FIGURE 31 ). Embolus-conductor-complex about half as long as bulb.
FEMALE. As in male except as noted. Body length 1.47–1.52 mm (n=4), carapace length 0.66–0.67 mm (n=4). Epigastric scutum posterolaterally with a row of longitudinal ridges (lr) ( Fig. 31F View FIGURE 31 ).
GENITALIA. Dorsal view ( Figs. 31 View FIGURE 31 F–G): receptaculum (re) triangular shaped with rounded posterior edge, laterally framed by long rectangular sclerites i.e. lateral apodemes (lap); apodemes distally weakly sclerotized and thus looking rather short in ventral view at stereomicroscope level; globular appendix (gap) lying dorsally of receptaculum about half as long as receptaculum; lateral and median part of receptaculum dorsally covered with papillae (pap); a transverse sclerite (ts) anteriorly to the receptaculum not observed, maybe lost during preparation.
Intraspecific variation. Body size variable (see above). Three males show honey-yellow colouration. Number of denticles on carapace margin varies. Extension of smooth median stripe on sternum slightly variable but never less than about 2/3 of sternum length.
Distribution. NE-Kalimantan, INDONESIA ( Fig. 49 View FIGURE 49 ).
