Etymology. The species epithet is dedicated to Bruno Manser (*1954, missing, presumed dead), a Swiss environmental activist and ethnologist, most famous for his support of the nomadic indigenous Penan people against the destruction of pristine rain forest in the Malaysian state of Sarawak (see www.bmf.ch).

Diagnosis. A. brunomanseri 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 with two pairs of spikes ( Figs. 9 View FIGURE 9 E–F); carapace margin with pointed denticles (den) and sluice (slu) restricted to posterior margin ( Figs. 9F View FIGURE 9 , 10A View FIGURE 10 ); epigastric scutum in females posterolaterally with a single curved ridge (cr) ( Fig. 11C View FIGURE 11 ). It resembles A. dayak sp. nov. and A. kolleri sp. nov., but A. dayak sp. nov. (only known from one female) lacks spikes and shows a row of longitudinal ridges on the epigastric scutum. Among other differences A. kolleri sp. nov. only has one pair of spikes, differs in sternum ornamentation and shows a pointed embolic spine.

Description. Description based on 5 males and 8 females.

MALE. With the characters of the genus except as noted. Body length 1.80–1.90 mm (n=5), carapace length 0.86–0.88 mm (n=5). Sclerotized parts uniformly coloured red-brown, approaching colour 32 ‘chestnut’; legs more orangish coloured, paler than rest of body. Habitus: Figs. 9 View FIGURE 9 A–C.

CEPHALOTHORAX. Carapace: surface of elevated portion of pars cephalica smooth, sides strongly reticulate (dorsal part more striated; Figs. 9 View FIGURE 9 D–F); posterior edge of pars cephalica with one pair of spikes (csp) ( Figs. 9 View FIGURE 9 C–F); carapace margin with pointed denticles (den), sluice (slu) restricted to posterior margin, posterolateral corners with one pair of spikes (msp) ( Figs. 9 View FIGURE 9 E–F, 10A). Eyes: posterior eye-row recurved from above, procurved from front ( Fig. 9E View FIGURE 9 ); 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 smooth median stripe and broadly smooth edges (ornamentation arranged in an ovoid band; Figs. 9 View FIGURE 9 G–H); posterior margin expands into narrow single extension, posteriorly with a knob-like apophysis (ka) ( Figs. 9H View FIGURE 9 , 10C View FIGURE 10 ); setae appearing slightly plumose at SEM level. Pleura: (pl) surface smooth with pairs of large pits dorsally of each coxa I, II and III ( Fig. 10B View FIGURE 10 ). Mouthparts: chelicerae posterior margin of inner surface proximally modified to a ridge with grooved surface (ri), covering about 2/3 of margin length, distally ending in a rounded knob ( Fig. 10D View FIGURE 10 ); promargin with row of flattened setae (rfs) in combination with plumose setae, distally extending into a short inwards pointing tooth-like projection (tlp) ( Figs. 10 View FIGURE 10 D–E); base of tooth-like projection posteriorly with a large plumose seta (lps) (about as long as fang; Fig. 10E View FIGURE 10 ). Endites: inner margin distally with a brush of special wing-like setae (ws) ( Figs. 10 View FIGURE 10 G–H); outer margin subdistally with a pair of rather long, inward bent plumose setae (ebs) ( Figs. 10 View FIGURE 10 F–G).

ABDOMEN. Book lung covers large, elongated elliptical to dumbbell shaped (i.e. sides concave), about 5–6 times longer than wide. Epigastric scutum dorsally with widely oval subterminal ridge (sr) ( Figs. 11 View FIGURE 11 A–B, D). Postepigastric scutum long, semicircular, with short posteriorly directed lateral apodemes (lap) ( Fig. 11A View FIGURE 11 ). Setae appearing slightly plumose at SEM level ( Fig. 11C View FIGURE 11 ); dorsal abdominal setae very long (lds) ( Figs. 9 View FIGURE 9 C–D, 11D).

GENITALIA. Epigastric region: sperm pore situated between anterior and posterior spiracles ( Fig. 11A View FIGURE 11 ). Palp: basal segments as well as bulb and cymbium lighter in colour than rest of body; bulb stout ( Figs. 12 View FIGURE 12 A–B). Embolus tip spatulate ( Figs. 12 View FIGURE 12 C–E); embolic spine with fringed tip (esp) ( Fig. 12C View FIGURE 12 ). Conductor (con) with pronounced lateral comb (lc) and broad tip ( Figs. 12C, E View FIGURE 12 ). Embolus-conductor-complex about as long as bulb.

FEMALE. As in males except as noted. Body length 1.88–2.21 mm (n=8), carapace length 0.88–0.97 mm (n=8). Epigastric scutum posterolaterally with a curved ridge (cr) ( Figs. 11 View FIGURE 11 B–C, 12F). Postepigastric scutum almost semicircular ( Fig. 11B View FIGURE 11 ).

GENITALIA. Dorsal view ( Figs. 12 View FIGURE 12 F–G): receptaculum (re) triangular shaped with rounded posterior edge, laterally framed by short almost rectangular sclerites (apodemes; lap) and containing a triangular sac-like structure (sa); globular appendix (gap) lying dorsally of receptaculum short, only about 1/4 of receptaculum length; lateral and median part of receptaculum dorsally covered with papillae (pap); a transverse sclerite (tsc) lies anteriorly to the receptaculum and bears medially a nail-like structure (na) (the latter being superimposed by globular appendix and therefore hardly visible on the figures).

Intraspecific variation. Body size variable (see above); except for two yellowish coloured females body colour shows only very slight variation; the following characters are slightly variable as well: size of ‘spikes’ at posterior edge of pars cephalica, number of denticles on carapace margin, extension of smooth median stripe on sternum.

Distribution. W-Sarawak, MALAYSIA ( Fig. 49 View FIGURE 49 ).
