(Figs. 16–17)
Type material. HOLOTYPE: male (PBI_OON 00015669), Pahang (MALAYSIA), Tioman Island, westside of Mount Kajang, 2 km E of Kampung Genting, 400 m [02°47′N 104°08′E; prov.], 2.VII.2001, leg. A. Schulz & K. Vock, deposited at MHNG. PARATYPE: 1 female (PBI_OON 00031385), collected together with holotype, deposited at MHNG.
Etymology. The species epithet is a Latin adjective meaning ‘to be descended from a dragon’. It refers to a legend saying that Tioman Island, on which lies the type locality, represents a resting dragon princess.
Diagnosis. A. draconigenum sp. nov. 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, sluice (slu) reaching from posterior margin to level of coxa I (Fig. 16D); epigastric scutum dorsally with a widely oval subterminal ridge (sr) (Fig. 16G), sides posterolaterally with a pair of single curved ridges (cr) (in female only; Fig. 17B) and a distally widened spinneret scutum (in male only; Fig. 16H). It highly resembles allopatric A. confluens sp. nov. but can be distinguished among others by smaller posterior eyes, broader posterior extension of the sternum and smaller body size.
Description. Description based on 1 male and 1 female.
MALE. With the characters of the genus except as noted. Body length 1.08 mm, carapace length 0.52 mm. Sclerotized parts uniformly coloured yellow-brown approaching colour 121C ‘mikado brown’; legs slightly paler than body. Habitus: Figs. 16 A–C.
CEPHALOTHORAX. Carapace: surface of elevated portion of pars cephalica smooth, sides finely reticulate (Figs. 16 C–D); 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. 16D); non-marginal pars thoracica setae present but sparse and scattered. Eyes: posterior eye-row straight from above, procurved from front; 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 tiny and circular, separated by less than PME radius. Sternum completely finely ornamented (Figs. 16 E–F). Pleura: surface smooth with pairs of large pits dorsally of each coxa I, II and III. Mouthparts: chelicerae promargin distally extending into a short inwards pointing tooth-like projection (tlp) (Fig. 16E); anterior face of paturon in lateral view subbasally slightly indented (Fig. 16C).
ABDOMEN. Book lung covers (bc) large, elongated elliptical, with parallel sides, about 3 times longer than wide (Fig. 16G). Epigastric scutum dorsally with widely oval subterminal ridge (sr) (Fig. 16G). Postepigastric scutum long, semicircular, with long posteriorly directed lateral apodemes (lap) (Fig. 17A). Pedicel tube finely ribbed. Spinneret scutum distally widened (Fig. 16H).
GENITALIA. Epigastric region: sperm pore situated between anterior and posterior spiracles (Fig. 17A). Palp: basal segments as well as bulb and cymbium lighter in colour than rest of body; bulb stout (Figs. 17 C–D). Embolus (em) tip elongated and spatulate (Figs. 17 C–D); embolic spine not observed. Conductor (con) with slender tip (Figs. 17 C–D). Embolus-conductor-complex slightly shorter than bulb.
FEMALE. Body length 1.19 mm, carapace length 0.54 mm. As in male except as noted. Lighter coloured than male, more yellowish, close to colour 123B ‘clay colour’. Proximal part of chelicerae posterior margin of inner surface upfolded to a ridge, covering about 2/3 of margin-length, distally ending in tooth-like projection (not possible to be examined in male). Epigastric scutum posterolaterally with a pair of single curved ridges (cr) (Fig. 17B). Postepigastric scutum with short posteriorly directed lateral apodemes (lap) (Fig. 17B). Spinneret scutum distally not widened (Fig. 17B).
Intraspecific variation. Body size variable (see above). Body colouration variable (see above).
Distribution. Tioman Island, MALAYSIA (Fig. 49).
