Aposphragisma kolleri Thoma View in CoL , sp. nov.

( Figs. 26–27 View FIGURE 26 View FIGURE 27 )

Type material. HOLOTYPE: male ( PBI_OON 00031373 ), Sarawak ( MALAYSIA), Bako National Park [01°42′N 110°27′E; inf.], 30.III.1985, lowland forest, litter, leg. C. Deeleman, deposited at RMNH GoogleMaps . PARATYPE: 1 male ( PBI_OON 00031386 ), collected together with holotype, deposited at RMNH GoogleMaps .

Etymology. The species epithet is dedicated to Markus Koller-Furrer (*1958), a Swiss teacher, naturalist and conservationist who promoted the first author’s ornithological and natural history skills from an early age.

Diagnosis. A. kolleri 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 one pair of spikes (csp) ( Figs. 26 View FIGURE 26 C–D); carapace margin with blunt denticles, sluice restricted to posterior margin ( Fig. 26D View FIGURE 26 ). The new species resembles A. brunomanseri sp. nov. and A. dentatum sp. nov. but differs from A. brunomanseri sp. nov. among others by the lack of a second pair of spikes on the carapace, by the sternum shape and the pointed embolic spine (esp) ( Fig. 27C View FIGURE 27 ), from A. dentatum sp. nov. among others by the shape of the carapace margin denticles, shorter claws (almost as long as tarsi in A. dentatum sp. nov.) and greater body length.

Description. Description based on 2 males.

MALE. With the characters of the genus except as noted. Body length 2.08–2.16 mm, carapace length 0.96 mm. Sclerotized parts uniformly coloured red-brown, approaching colour 32 ‘chestnut’; legs paler, orangish. Habitus: Figs. 26 View FIGURE 26 A–C.

CEPHALOTHORAX. Carapace: surface of elevated portion of pars cephalica smooth, sides strongly reticulate ( Fig. 26D View FIGURE 26 ); posterior edge of pars cephalica with one pair of spikes (csp) ( Figs. 26 View FIGURE 26 C–D); carapace margin with sluice restricted to posterior margin, with blunt denticles ( Figs. 26 View FIGURE 26 D–E). Eyes: posterior eye-row straight from above, procurved from front ( Figs. 26D, F View FIGURE 26 ); 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 finely ornamented except smooth median stripe ( Fig. 26E View FIGURE 26 ); posterior margin with narrow single extension, covered with blunt denticles ( Fig. 26E View FIGURE 26 ; cf A. brunomanseri sp. nov.). Pleura: surface smooth with pairs of large pits dorsally of each coxa I, II and III. 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 bulge; promargin with row of flattened setae, distally extending into a short inwards pointing tooth-like projection (tlp) ( Fig. 26F View FIGURE 26 ); posterior face with a pair of long, spatulate setae.

ABDOMEN. Book lung covers (bc) large, elongated, elliptical to rather dumbbell shaped (sides concave), about 4–5 times longer than wide ( Fig. 26G View FIGURE 26 ). Epigastric scutum dorsally with widely oval subterminal ridge (sr) ( Fig. 26G View FIGURE 26 ); scuto-pedicel region with slightly swollen hair bases. Postepigastric scutum long, semicircular, with long posteriorly directed lateral apodemes ( Fig. 26H View FIGURE 26 ). Dorsal abdominal setae shorter than in A. brunomanseri sp. nov. ( Fig. 26G View FIGURE 26 , cf fig. 9C).

GENITALIA. Epigastric region: sperm pore situated between anterior and posterior spiracles ( Fig. 26H View FIGURE 26 ). Palp: basal segments as well as bulb and cymbium lighter in colour than rest of body; bulb stout ( Figs. 27 View FIGURE 27 A–B). Embolus (em) medially with longitudinal ridges on prolateral surface, tip spatulate ( Fig. 27C View FIGURE 27 ); embolic spine (esp) with pointed tip ( Fig. 27C View FIGURE 27 ). Conductor (con) with broad tip (appearing ‘snout’-like in lateral view; Fig. 27C View FIGURE 27 ). Embolusconductor-complex as long as bulb.

Intraspecific variation. Body size variable (see above); male paratype slightly paler and with slightly longer spikes on carapace.

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