Geogarypus sagittatus Beier, 1965

( Figs 3A‒K )

Material examined. 1 ♀ ( HNHM Pseud-1993), Angoram , Papua New Guinea, 13 Aug. 1969, collected by knocking trees in the rainforest alongside paths and at the forest edge.

Supplementary description (female). General appearance as in Fig. 3A . Carapace granulate, with small clavate setae ( Fig. 3B ), two smaller clavate and two longer spear-shaped setae near anterior margin ( Fig. 3C ). Cheliceral setation typical for the genus ( Fig. 3D ). Two subterminal teeth on fixed cheliceral finger, no teeth visible on movable finger. Galea simple. Serrula exterior with 13‒14 blades, distal 2 enlarged and pointed, proximal 2 enlarged, of which the distal one is clavate and the proximal one hooked ( Fig. 3E ). Pedipalpal femur ( Fig. 3F ) with normal granulation, no enlarged tubercles present, setae clavate and acuminate ( Figs 3G, H ). Chelal fixed finger ( Fig. 3I ) with 17 widely spaced teeth, pointed and backwards-curved in distal quarter, then becoming conical. Retrolateral face of fixed finger with 9 accessory teeth between est and et. Movable finger with 22 slightly spaced teeth, which are inclined backwards in distal half but become flattened in the proximal half. Retrolateral face of fixed chelal finger with 4 pit-like structures. Female genital region: sternite II with 3+3 microsetae and two lyrifissures, sternite III with 2 microsetae and 2 lyrifissures near genital opening. One pair of elongated lateral cribriform plates and a medial cribriform plate present, but these are weakly visible. Median setae of sternites show no differences from the other setae. Legs ( Figs 3J, K ) diplotarsate and without tactile setae, surface mostly granulate. Claws simple. Arolia slightly longer than claws.

Dimensions (in mm, ratios in parentheses). Body 1.43; carapace 0.51/0.63 (0.81×). Chelicera 0.15/0.09, movable finger 0.10. Pedipalpal trochanter 0.23/0.16 (1.43×); femur 0.51/0.15 (3.42×); patella 0.36/0.14 (2.57×). Chela (with pedicel) 0.81 (3.24×); pedicel 0.05; hand 0.35/0.25 (1.4×); fingers 0.44. Leg I trochanter 0.11/0.10 (1.10×); femur 0.21/0.08 (2.64×); patella 0.14/0.10 (1.41×); tibia 0.15/0.06 (2.49×); basifemur 0.12/0.05 (2.40×); patella 0.12/0.03 (4.02×). Leg IV trochanter 0.20/0.12 (1.67×); basifemur 0.12/0.07 (1.71×); patella 0.29/0.12 (2.42×); tibia 0.226/0.07 (3.71×); metatarsus 0.16/0.05 (3.19×); tarsus 0.13/0.04 (3.25×).

Remarks. The characters of this specimen from Papua New Guinea correspond well with the original description ( Beier 1965), including the coloration, which fully matches Beier’s figure ( Beier 1965: fig. 7). However, since the original description does not include several characters of taxonomic importance, some supplementary features are described here from the new specimen. Beier (1965) described the species as a member of the subgenus Indogarypus ( Beier 1965) , but it was later excluded from Indogarypus when Harvey (1986) elevated it to genus level, because the prolateral constriction of the chelal hand near the base of the fingers is much weaker than in the type species of the genus, I. indicus (Beier, 1930) (Beier 1930; Harvey 1986). Geogarypus sagittatus has been reported from Papua New Guinea and West Papua ( Beier 1965, 1982), and is probably endemic to the island of New Guinea.
