Aposphragisma salewskii Thoma View in CoL , sp. nov.

( Figs. 42–43 View FIGURE 42 View FIGURE 43 )

Type material. HOLOTYPE: male (PBI_OON 00031387), Bukit Timah Nature Reserve ( SINGAPORE) [01°21′N 103°47′E; inf.], 21.II.1983, leg. C. Deeleman, deposited at RMNH GoogleMaps . PARATYPE: 1 male (PBI_OON 00031351), collected together with holotype, deposited at RMNH GoogleMaps .

Etymology. The species epithet is dedicated to Dr. Volker Salewski (*1964), a German biologist and naturalist, whose scientific work, attitude and friendship have been an inspiration for the first authors’ own work and life.

Diagnosis. A. salewskii sp. nov. belongs to the stripe-clade and can be distinguished from other species of this clade by the combination of the following traits: elevated portion of pars cephalica granulate ( Fig. 42F View FIGURE 42 ); carapace without spikes; carapace margin with pointed denticles, sluice restricted to posterior margin ( Fig. 42D View FIGURE 42 ).

Description. Description based on 2 males.

MALE. With the characters of the genus except as noted. Body length 1.90–1.91 mm (n=2), carapace length 0.91–0.92 mm (n=2). Sclerotized parts uniformly coloured red-brown, approaching colour 132A ‘brick red’; legs paler than body, orange-brown. Habitus: Figs. 42 View FIGURE 42 A–C.

CEPHALOTHORAX. Carapace: surface of elevated portion of pars cephalica granulate ( Fig. 42F View FIGURE 42 ), sides strongly reticulate, partly interrupted by small smooth areas ( Fig. 42D View FIGURE 42 ); posterolateral surface without spikes; posterior edge of pars cephalica with slightly stronger modified hair bases, appearing as pointed denticles; carapace margin with sluice restricted to posterior margin, with pointed denticles ( Fig. 42D View FIGURE 42 ). Eyes: posterior eye-row recurved from above, procurved from front ( Figs. 42D, F View FIGURE 42 ); 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 surface finely ornamented except smooth median stripe ( Fig. 42E View FIGURE 42 ); posterior margin with narrow single extension, covered with blunt denticles ( Fig. 42E View FIGURE 42 ). Pleura: surface smooth with pairs of large pits dorsally of each coxa I, II and III (as in A. brunomanseri sp. nov., Fig. 10B View FIGURE 10 ). Mouthparts: chelicerae promargin with row of flattened setae, distally extending into a short inwards pointing tooth-like projection (tlp) ( Fig. 42E View FIGURE 42 ).

ABDOMEN. Book lung covers (bc) large, elliptical, slightly dumbbell shaped (sides slightly concave to parallel), about 3–4 times longer than wide, much darker than surroundings ( Fig. 42G View FIGURE 42 ). Epigastric scutum dorsally with widely oval subterminal ridge (sr) ( Fig. 42G View FIGURE 42 ). Postepigastric scutum almost semicircular, with short posteriorly directed lateral apodemes (lap) ( Fig. 42H View FIGURE 42 ).

GENITALIA. Epigastric region: sperm pore situated between anterior and posterior spiracles ( Fig. 42H View FIGURE 42 ). Palp: basal segments as well as bulb and cymbium lighter in colour than rest of body; bulb stout ( Figs. 43 View FIGURE 43 A–B). Embolus (em) tip spatulate ( Figs. 43 View FIGURE 43 A–C); embolic spine (esp) with pointed tip ( Fig. 43C View FIGURE 43 ); conductor (con) with broad tip ( Fig. 43C View FIGURE 43 ). Embolus-conductor-complex about as long as bulb.

Distribution. Bukit Timah, SINGAPORE ( Fig. 49 View FIGURE 49 ).
