Treatment

Aposphragisma retifer Thoma View in CoL , sp. nov.

( Figs. 36–37 View FIGURE 36 View FIGURE 37 )

Type material. HOLOTYPE: male (PBI_OON 00016080), Sarawak ( MALAYSIA), Gunung Gading National Park near Lundu, primary forest, 250–500 m [01°41′17′′N 109°51′05′′E; prov.], 30.V.–1.VI.2007, leg. A. Schulz, deposited at MHNG GoogleMaps . PARATYPE: 1 female ( PBI_OON 00032177 ), collected together with male holotype, deposited at MHNG .

Etymology. The species epithet, a noun in apposition, is a combination of the Latin words for net (retis) and carry (ferre), referring to the net-like reticulation of the carapace surface.

Diagnosis. A. retifer 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) reaching from posterior margin to level of coxa I ( Fig. 36D View FIGURE 36 ); epigastric scutum in females posterolaterally with a row of longitudinal ridges. It closely resembles allopatric A. hausammannae sp. nov. but see there for differentiation.

Description. Description based on 1 male and 1 female.

MALE. With the characters of the genus except as noted. Body length 1.57 mm, carapace length 0.74 mm. Sclerotized parts uniformly coloured orange brown, close to colour 123A ‘cinnamon’; legs slightly paler than body. Habitus: Figs. 36 View FIGURE 36 A–C.

CEPHALOTHORAX. Carapace: surface of elevated portion of pars cephalica smooth, sides strongly reticulate, partly interrupted by small smooth areas ( Fig. 36G View FIGURE 36 ); posterolateral surface without spikes ( Figs. 36D, G View FIGURE 36 ); posterior edge of pars cephalica with slightly stronger modified hair bases, appearing as small denticles; carapace margin with sluice (slu) reaching from posterior margin to level of coxa I, with blunt denticles ( Fig. 36D View FIGURE 36 ). Eyes: posterior eye-row straight from above, procurved front; ALE largest, separated by less than their radius; ALE-PLE touching; PME touching throughout most of their length; PLE-PME touching. Sternum finely ornamented except smooth median stripe ( Figs. 36 View FIGURE 36 E–F); posterior margin with broad single extension. Pleura: surface smooth with pairs of large pits dorsally of each coxa I, II and III ( Fig. 36G View FIGURE 36 ). Mouthparts: chelicerae promargin with row of flattened setae, distally extending into a short inward pointing tooth-like projection (tlp) ( Fig. 36E View FIGURE 36 ); paturon anterior face in lateral view subbasally with angular indention (ind) ( Fig. 36G View FIGURE 36 ).

ABDOMEN. Book lung covers large, elongated ovoid (sides almost parallel), about 3 times longer than wide ( Fig. 36H View FIGURE 36 ). Epigastric scutum dorsally with widely oval subterminal ridge (sr) ( Fig. 36H View FIGURE 36 ). Postepigastric scutum long, semicircular, with short posteriorly directed lateral apodemes (lap) ( Fig. 37A View FIGURE 37 ).

GENITALIA. Epigastric region: sperm pore situated between anterior and posterior spiracles ( Fig. 37A View FIGURE 37 ). Palp: colouration of basal segments about as rest of body but bulb and cymbium lighter ( Fig. 37C View FIGURE 37 ); bulb rather stout ( Figs. 37 View FIGURE 37 C–D). Embolus (em) tip spatulate ( Fig. 37E View FIGURE 37 ); embolic spine (esp) with fringed tip ( Fig. 37E View FIGURE 37 ). Conductor (con) with broad tip (appearing ‘snout’-like in lateral view; Fig. 37E View FIGURE 37 ). Embolus-conductor-complex about as long as bulb ( Figs. 37 View FIGURE 37 C–D).

FEMALE. As in male except as noted. Body length 1.69 mm, carapace length 0.75 mm. Colouration darker, close to colour 136 ‘raw sienna’. Epigastric scutum posterolaterally with a row of longitudinal ridges (as in A. helvetiorum sp. nov., Fig. 23H View FIGURE 23 ).

Intraspecific variation. Body size and colour variable (see above).

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