Morphology
General features —Idiosoma elongated (dorsal shield L/W ratio 1.6-1.7); shoulder plates elongated (shoulder/ frontal plate L ratio 1.2-1.3); frontal margin with flat protrusions medial to the eyes; Cxgl-4 located far anteriorly, near tips of Cx-I; gnathosomal bay U-shaped; suture line of Cx-IV lightly accentuated, originating from lateral edge of genital field and extending posteriorly beyond posterior margin of genital field ( Figs. 29 View FIGURE 29 A-B); Vgl-2 posterior to excretory pore; P-2 and P-3 distal margins without pointed tips, P-4 without denticles near insertion of ventral setae. Male: medial margin of Cx-II/III relatively long; genital field subrectangular; ejaculatory complex normal in shape (proximal and distal arms and proximal chamber well developed, Fig. 30A View FIGURE 30 ); excretory pore and Vgl- 2 slightly away from the line of primary sclerotization, near posterior margin of idiosoma. Female: genital field pentagonal, anteriorly enlarged, laterally straight, tapering posteriorly ( Fig. 29B View FIGURE 29 ); excretory pore and Vgl- 2 located posterior to line of primary sclerification.
Remarks. The specimens from Borneo agree well in general morphology with Monatractides longiventris , a species originally described from Java (K. Viets 1939). The original description was restricted to the male; a first description of the female from Central Java was given by Lundblad (1971). In comparison with the holotype, specimens examined in our study are smaller, but do not differ in proportions and general idiosoma and palp morphology ( Table 1 View TABLE 1 ).
Distribution. Java (“ Atractides longiventris ” K. Viets 1939 , “ T. longiventris ” Lundblad 1971 ). New for Borneo.
