( Figure 6 ) Material examined — Holotype female, River at km. 13, Doi Inthanon NP , Thailand , 18°31.532N 98°39.091E , alt. 465 m a.s.l. , 25-xi-2007 . Paratypes : four females , Stream W of Bankrang Camp , Kaeng Krachan NP, Thailand , 12°48.106N 99°26.786E , 20- xi-2007 . Diagnosis — Dorsal shield with a posterior extension; three platelets in dorsal furrow fused to one elongated platelet, A2 fused with dorsal shield. Description — Female: Idiosoma pale yellow, dorsally 405 (381 – 405) long and 300 (284 – 292) wide, ventrally 344 (247 – 251) long. Dorsal shield separated with a posterior extension, separated from ventral shield, and appears therefore in dorsal view as incomplete; dorsal shield 251 (247 – 251) wide. A2 fused with dorsal shield. Three pairs of glandularia lying in dorsal furrow on an elongated platelet. Postocularia lying posteromedially of dgl- 1, the latter lying close to margin of dorsal shield. Suture lines of coxae obliterated, only suture lines of Cx-III and Cx-IV present to some extent, other suture lines nearly absent. Cxgl-4 between fourth leg sockets and genital field, lying somewhat closer to genital field. Genital field 126 wide, with thee pairs of acetabula lying in a line, genital plates connected by a small strip of sclerotization. Vgl-4 lying on a small platelet, not fused to coxae. Excretory pore not lying on a small platelet, posterior to the genital field, touching postgenital sclerite but not fused. Length of P1-P5: -, 30, 22, 46, 24. Length of I-leg-4-6: 40, 46, 42 (till tip of segment. Length of IV-leg-4-6: 42, 48, 42 (till tip of segment). Swimming setae absent. Male: Unknown. Etymology — Named for the very different dorsal shield compared to other Javalbia species. FIGURE 6: Javalbia discrepans n. sp . , holotype female: A – dorsum; B – venter; C – palp. Scale bars = 50 µm. Remarks — The dorsal shield with a posterior extension is not found in any other Javalbia species. Moreover, the fused glandularia platelets in the dorsal furrow are also unique.
