description: Aposphragisma confluens Thoma, sp. nov.
(Fig. 13)
Type material. HOLOTYPE: female (PBI_OON 00015238), Sarawak (MALAYSIA), E of Kapit, Tr. Narwin at confluence of Suan Oyen River and Mujong River, 150 m [02°02′N 113°01′E; inf.], 19.V.1994, secondary mixed dipterocarp forest along ridge, sifting of vegetational debris, leg. I. Löbl & D. Burckhardt, deposited at MHNG.
Etymology. The species epithet is a noun in apposition meaning ‘confluence’ in Latin. It refers to the type locality at the confluence of Suan Oyen River and Mujong River on Borneo.
Diagnosis. A. confluens sp. nov. is only known from one female and does not belong to the stripe clade and thus shows a completely ornamented sternum. It can be distinguished from other species with a completely ornamented sternum by the combination of the following traits: carapace margin with blunt denticles (Fig. 13D), sluice (slu) reaching from posterior margin to level of coxa I (Fig. 13C), epigastric scutum dorsally without a widely oval subterminal ridge and sides posterolaterally with a single curved ridge (cr) (Fig. 13H). It highly resembles allopatric A. draconigenum but can be distinguished among others by the larger posterior eyes and the larger body size.
Description. Description based on 1 female.
FEMALE. With the characters of the genus except as noted. Body length 1.65 mm, carapace length 0.74 mm. Sclerotized parts uniformly coloured yellow-brown, very close to colour 123A ‘cinnamon’; legs only slightly paler than body. Habitus: Figs. 13 A–B.
CEPHALOTHORAX. Carapace: surface of elevated portion of pars cephalica smooth, sides finely reticulate (Figs. 13C, E); posterolateral surface without spikes; 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. 13C); non-marginal pars thoracica setae scattered. Eyes: posterior eye-row straight or slightly procurved from above, procurved from front (Figs. 13C, F); ALE largest, separated by less than their radius; ALE-PLE separated by less than ALE radius; PME touching for less than half their length; PLE-PME separated by less than PME radius. Sternum completely finely ornamented (Fig. 13D). Pleura: surface smooth with pairs of large pits dorsally of each coxa I, II and III (Fig. 13E).
ABDOMEN. Book lung covers (bc) large, elongated elliptical to slightly pear-shaped (i.e. sides concave), about 4 times longer than wide (Fig. 13G). Epigastric scutum dorsally without widely oval subterminal ridge (Fig. 13G), posterolaterally with a single curved ridge (cr) (Fig. 13H). Postepigastric scutum long, semicircular, with short posteriorly directed lateral apodemes (lap) (Fig. 13H).
Distribution. Central Sarawak, MALAYSIA (Fig. 49).
