Fig. 5: Pristomyrmex schoedli sp.n. , habitus, dorsal view (Matthias Buch pinxit).
Diagnosis of worker: Ventral surface of clypeus with strongly prominent tooth at centre. Clypeus without median carina, anterior margin usually with seven (rarely five) small denticles. Pronotum with pair of very long spines (PSL1 0.38 - 0.44), which are much longer than propodeal spines (PSL2 0.09 - 0.13). Dorsum of head and alitrunk smooth and polished; dorsum of head with scarce punctures (hair pits). Frontal carinae posteriorly faded; antennal scrobes indistinct. Anterior face of petiolar node distinct from dorsal surface of peduncle. Petiolar node with two or three pairs of hairs.
Measurements: Holotype worker: TL 4.44, HL 1.04, HW 1.15, CI 110, SL 1.17, SI 102, EL 0.22, PW 0.70, AL 1.05, PPW 0.30, PPL 0.32, PPI 94. - Paratype workers (n = 10): TL 4.19 - 3.41, HL 0.99 - 1.10, HW 1.12 - 1.23, CI 113 - 121, SL 1.19 - 1.28, SI 103 - 107, EL 0.21 - 0.26, PW 0.72 - 0.75, AL 1.04 - 1.16, PPW 0.29 - 0.32, PPL 0.30 - 0.37, PPI 104 - 118.
Figs. 6 - 7: Pristomyrmex schoedli sp.n. (6) Head, full face view; (7) habitus, lateral view.
Description of worker: Head (Fig. 6): Mandibles smooth and shiny, with or without a few longitudinal rugae. Masticatory margin of mandible with four teeth: strongest apical + second strongest preapical + long diastema + two small basal teeth of similar size. Basal margin of mandible almost straight, lacking tooth. Clypeus short, without median longitudinal carina. Anterior clypeus margin with short median tooth and three (rarely two) pairs of short lateral denticles. Ventral centre of clypeus with prominent tooth. Palp formula 1, 3. Frontal carinae anteriorly strongly developed, posteriorly indistinct and extending caudad at most to level of posterior eye margins, but usually shorter. Antennal scrobes indistinct, laterally not delimited. Frontal lobes absent; antennal insertion entirely exposed. Frons anteriorly with very fine median impression, variably reduced to short longitudinal groove. Antennal scapes, when lying on dorsum of head, slightly surpassing occipital margin of head. Eyes containing c. 10 - 12 ommatidia in longest row. Profile shape of alitrunk and pedicel segments as in Fig. 7. Pronotum with pair of long spines, PSL1 0.38 - 0.44. Propodeum with pair of short spines, PSL2 0.09 - 0.13, distinctly shorter than distance between apices. Dorsum of alitrunk somewhat flattened, behind pronotal spines almost straight in lateral view. Metapleural lobes almost rectangular, with acute or weakly rounded apex. Petiole in profile with long peduncle; peduncle distinct from anterior surface of node; node with weakly developed angles, anterodorsal one on slightly higher level than posterodorsal one. Postpetiole in profile rounded dorsally, in dorsal view slightly broadening from front to back. Dorsum of head smooth and polished, with some very fine hair pits; scrobal areas anteriorly with few transverse wrinkles. Dorsum of alitrunk smooth and polished, with only a few, very fine hair pits. Petiole, postpetiole, and gaster smooth and shiny. Dorsal surfaces of head and alitrunk with numerous long erect or suberect hairs. Dorsum of petiolar node with 2 - 3 pairs of hairs; dorsum of postpetiole with several pairs. First gastral tergite lacking erect or suberect hairs. A few pairs of forward projecting hairs present near anterior clypeal margin. Scapes and tibiae with numerous erect to suberect hairs. Colour reddish-brown.
Comparative notes: This species is similar to P. curvulus, but differs in the absence of a median carina on the clypeus and in the reduced frontal carina. From P. longispinus this species differs in the shape of the petiole, in the relatively short propodeal spines and in shorter pilosity. The cephalic index of P. schoedliHNS sp.n. (113 - 221) is slightly larger than in P. curvulusHNS and P. longispinusHNS (97 - 105 and 103 - 109; data from Wang 2003).
