Measurements

(in mm, length/width). ♂. Body length 1.57. Pedipalp: trochanter 0.22/0.16, femur 0.55/0.13, patella 0.40/0.15, chela 0.91/0.23, hand with pedicel 0.44/0.23, fixed finger length 0.51. Carapace 0.53-0.55/0.64.

Identification.

Geogarypus longidigitatus is remarkably similar to G. ocellatus Mahnert, 1978, as both possess the same pattern of carapace coloration, but the palpal patella and chela of G. ocellatus are more slender than in G. longidigitatus (e.g. patella and chela: G. longidigitatus 2.5-2.6 × longer than broad and 3.5-4.2 × longer than broad vs. G. ocellatus 3.0-3.3 × longer than broad and 4.1-4.5 × longer than broad) ( Mahnert 1978b; Harvey 2000). See Harvey (2000) for the complete redescription of G. longidigitatus and diagnosis of other geogarypid species. Newly described geogarypids found in the Asian-Australian-Pacific regions differ from G. longidigitatus as follows: G. muchmorei Novák & Harvey, 2018 differs by its larger area of brown coloration on the carapace and the swollen margin of the chelal hand; G. klarae Novák & Harvey, 2018 differs by having a white palpal trochanter and strongly curved teeth on the fixed chelal finger ( Novák and Harvey 2018); G. plusculus Cullen & Harvey, 2021 and G. facetus Cullen & Harvey, 2021 differ by the patchy coloration of the carapace and brighter palpal trochanter and femur ( Cullen and Harvey 2021).

Remarks.

The species is widely distributed in the Indo-Pacific region ( Novák and Harvey 2018; WPC 2022). Harvey (2000) assumed that the wide distribution of the species is also due to human activities.
