Type material

Holotype, male, (RMNH.ARA.15913), Malaysia, Borneo, west Sabah, Mt. Kinabalu National Park ; 6.15°N, 116.50°E; 5 year old secondary forest, 500–700 m, fogging canopy tree 1 Melochia umbellata , 16 February 1997, leg. A. Floren, loc 19. GoogleMaps

Etymology

This species is named after the collector Andreas Floren.

Diagnosis

Distinguished from known congeners by the distinctive E (broad base, tapering towards tip, bifurcate tip; Figure 4 View Figure 4 (a)), C (prolateral margin grooved to accommodate E, enlarged tip; Figure 4 View Figure 4 (a)) and RTA (tapered, fine tip; Figure 4 View Figure 4 (a)). Females are distinguished by the globular S, relatively longer CD and except for E. longimanus by the deeply indented anterior margins of the epigynum ( Figure 4 View Figure 4 (c, d)).

Description

Male. Total length: 3.7; prosoma length: 1.8, width: 1.5. Leg I: femur 3.0, patella 0.6, tibia 3.6, metatarsus 3.0, tarsus 1.4. Prosoma light brown/yellow, eye regions darker, without prominent markings or conspicuous setae. Opisthosoma with white spots, dorsally with a dark brown folium and spots. ALE = PLE> PME> AME. AER, PER recurved, eyes on brown-coloured mounds, but not touching. Chelicerae with 3 and 2 teeth on pro- and retromargin of fang furrow, respectively. Leg formula 1243. Palps as in Figure 4 View Figure 4 (a), femur and tibia characteristically elongated, femur as long as tibia, furnished with around 6 thick long spines and MTr. RTA present, tapered, fine tip. Bulbus ovoid, conductor prolateral margin grooved to accommodate E. E stout tip, not serrated. MA absent. Embolus stout, enlarged, bifurcate tip ( Figure 4 View Figure 4 (a)).

Female. Total length: 5.4; prosoma length: 2.2, width: 1.9. Leg I: femur 3.0, patella 0.9, tibia 3.1, metatarsus 2.1. tarsus 1.2. In general similar to male ( Figure 2 View Figure 2 (b)). Epigynum

without hood, anterior margin deeply indented, dual-chambered S connected by a C-shaped, thick-walled CD ( Figure 4 View Figure 4 (c, d)).
