? Martensiellus n. g. spp.

Figs 18–22

Two females from other parts of Borneo possess the same characteristics in somatic morphology (tarsal formula 1­1­2­2, leg tarsi/tarsomeres fairly large, a tarsal pore present on legs I and II) that place M. tenuipalpus n. sp. apart from all other described oncopodid species. I assume that these females also belong to Martensiellus n. g. and represent two undescribed species distinct from M. tenuipalpus n. sp. However, generic placement without conspecific males is uncertain and I therefore refrain from formally describing and naming them.

1. female (MHNG): Eastern Malaysia, Sarawak, Mulu National Park, near headquarters (4°00’N, 114°49’E), 200 m, collected on 19–24 August 2003 from rain forest leaf litter by A. Schulz. Different from the males of M. tenuipalpus n. sp. by: Body distinctly smaller (2.75 mm long); eye tubercle more conical (Fig. 18); legs more slender and palpal tibia thicker; carapace­opisthosoma bridge present, divided; tiny process on palpal trochanter; distinct ventral process on proximal article of chelicera (Fig. 18); tarsus of leg II relatively longer (Fig. 19).

2. female (collection of C. Deeleman­Reinhold; mentioned in Martens & Schwendinger 1998: 548): Indonesia, Central Kalimantan Province, Kaharian (2°02’S, 113°40’E), collected from the leaf litter of a swampy primary forest on 2–16 October 1985 by S. Djojosudharmo. Different from males of M. tenuipalpus n. sp. by: Body much larger (5.19 mm long); eye tubercle broadly rounded; carapace­opisthosoma bridge present, undivided (Fig. 20); legs more slender and papal tibia thicker; process on palpal trochanter large, bifid (Fig. 20); chelicera more robust, with distad­directed dorsodistal process on proximal article and ventrodistal process on second article (Fig. 21). Tarsus of leg II (Fig. 22) similar to that of M. tenuipalpus n. sp. (Fig. 7).
