Pyramica deyrupi

Identification
Bolton (2000) - A member of the Strumigenys pulchella-group. In addition to the comparative features noted under Strumigenys creightoni, Strumigenys deyrupi differs from Strumigenys metazytes as the latter has distinctly smaller and narrower spongiform lobes on the waist segments. As well as the character noted in the key, the petiole of metazytes in profile has the maximum length of the lateral lobe less than half the length of the node; in deyrupi this lobe is distinctly greater than half the node length. The size difference in clypeal pilosity between the hairs located mid-dorsally and those that fringe the lateral margins is obviously different in deyrupi and Strumigenys abdita, and easily discerned even under low magnification.

P. deyrupi bears a striking resemblance to Strumigenys talpa, but in the latter species all the hairs on the leading edge of the scape are curved toward the scape apex.

Worker
Holotype. TL 1.9, HL 0.52, HW 0.33, CI 63, ML 0.09, MI 17, SL 0.26, SI 79, PW 0.22, AL 0.48. Anterior clypeal margin almost transverse in full-face view. Dorsum of clypeus with numerous small short spatulate hairs that are somewhat elevated and curved anteriorly; these hairs tiny by comparison with the long, laterally projecting, anteriorly curved spatulate to narrowly spoon-shaped hairs that fringe the lateral clypeal margins. Dorsolateral margin of head with a flagellate apicoscrobal hair. Cephalic ground pilosity curved and narrowly spatulate, elevated; vertex near occipital margin with a pair of longer erect flagellate hairs. Pronotal humeral hair very long and fine, flagellate. Pronotal dorsum with 1 pair of erect flagellate hairs; mesonotum with a pair of flagellate hairs. Hairs on first gastral tergite very fin e and flagellate ; similar hairs present on waist segments. Hind basitarsus with a fine flagellate hair projecting from the dorsal (outer) surface close to its base. Basigastral costulae coarse, strongly developed, extending over the basal quarter of the tergite.
