description: Aposphragisma retifer Thoma, sp. nov.
(Figs. 36–37)
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. 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); 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 A–C.
CEPHALOTHORAX. Carapace: surface of elevated portion of pars cephalica smooth, sides strongly reticulate, partly interrupted by small smooth areas (Fig. 36G); posterolateral surface without spikes (Figs. 36D, G); 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). 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 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). Mouthparts: chelicerae promargin with row of flattened setae, distally extending into a short inward pointing tooth-like projection (tlp) (Fig. 36E); paturon anterior face in lateral view subbasally with angular indention (ind) (Fig. 36G).
ABDOMEN. Book lung covers large, elongated ovoid (sides almost parallel), about 3 times longer than wide (Fig. 36H). Epigastric scutum dorsally with widely oval subterminal ridge (sr) (Fig. 36H). Postepigastric scutum long, semicircular, with short posteriorly directed lateral apodemes (lap) (Fig. 37A).
GENITALIA. Epigastric region: sperm pore situated between anterior and posterior spiracles (Fig. 37A). Palp: colouration of basal segments about as rest of body but bulb and cymbium lighter (Fig. 37C); bulb rather stout (Figs. 37 C–D). Embolus (em) tip spatulate (Fig. 37E); embolic spine (esp) with fringed tip (Fig. 37E). Conductor (con) with broad tip (appearing ‘snout’-like in lateral view; Fig. 37E). Embolus-conductor-complex about as long as bulb (Figs. 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).
Intraspecific variation. Body size and colour variable (see above).
Distribution. W-Sarawak, MALAYSIA (Fig. 49).
