Description

Worker

Holotype. HL, 0.61 mm.; HW, 0.41 mm.; SL, 0.38 mm.; CI, 67; SI, 93; WL, 80.0 mm.; PW, 0.30 mm.; dorsal petiole width, 0.17 mm.; petiolar node index, 57; petiole height, 0.31 mm.; petiolar node length, 0.25 mm.; lateral petiolar index, 84. General features are shown in the figures. Close to Probolomyrmex filiformis, but differing from it in the following characters: (1) Smaller size, with relatively broad head. short scapes, and narrow, shorter petiolar node- as indicated in the above dimensions. (2) Punctural element of sculpturation more distinct (shagreening developed on all body and appendage surfaces, as in filiformis). Head capsule with moderately distinct superficial punctures, about 0.005 mm. in diameter, separated by distances about equal to their average diameter; those on sides and postgenal areas most distinct. Puncturation of entire pronotum and remaining mesosomal dorsum similar to frons; punctures of mes- and metepisterna larger and more distinct. Petiole and first 2 segments of gaster with larger shallow punctures, about 0.01 mm. in diameter, separated by distances averaging about half this value. (3) Concavity of declivitous propodeal face, viewed from above, about onequarter as deep as distance separating dorsal points of propodeal lamellae. (4) Subpetiolar process lacking an acute posteroventral tooth. When viewed from above, no trace of a median emargination of the posterior flange of the node.

P. guineensis resembles Probolomyrmex filiformis in all other respects, apart from slightly paler coloration. The three apical maxillary and the terminal labial palpal segments are proportioned as in Probolomyrmex angusticeps.

Paratypes. Two paratype workers agree with the holotype in all essential characters, including details of the measurements and indices.

Type Material

Holotype worker and 2 worker paratypes, GUINEA: Nigorie, Kakoulima (Silvestri). The holotype is deposited in the Naturhistorisches Museum, Basel, paratypes in the British Museum (Nat. Hist.) and the Museum d'Histoire Naturelle, Geneva. There are differences in the original labels on these specimens. That of the holotype reads: Nigorie, Kakoulima (Silvestri); the Geneva Museum specimen has: Kakoulima 12 Ag. 1912; and the British Museum one has: French Guinea-d. F. Santschi-G. A. (presumably G. Arnold)-1914.
