Description

Worker

Eguchi 2001. Fig. 13. Lectotype of Pheidole rinae Emery: A, major, head in full-face view; B, same, head in profile; C, same, alitrunk in dorsal view; D, same, alitrunk in profile.

Eguchi (2001) - Major (lectotype). HL 0.99 mm; HW 0.91 mm; SL 0.47 mm; PW 0.46 mm; FL 0.63 mm; CI 92; SI 52; FI 69. Head broadest at 3/5 distance of head (from anterior margin of clypeus to posterior margin of occipital lobe) (Fig. 13A); head in profile impressed on vertex (Fig. 13B); anteroventral margin of cranium bearing 3 median processes. Clypeus without a median longitudinal carina. Eye situated at about 1/3 distance of head; distance between mandibular insertion and lower margin of eye 1.3 times as long as maximal diameter of eye. Frontal carina weak, extending to about 3/5 distance of head. Antennal scrobe present only around antennal insertion. Masticatory margin of mandible with apical and preapical tooth, and a distinct denticle in front of basal angle. Antenna with 3-segmented club; scape reaching about 2/3 distance of head; terminal segment ca. 1.2 times as long as preceding two segments together. Promesonotum forming a high dome, in profile with an inconspicuous prominence on its posterior declivity (Fig. 13D); dorsal portion of the dome weakly produced laterally (arrow in Fig. 13C). Mesopleuron with an inconspicuous transverse impression. Propodeal spine triangular, ca. 3 times as long as diameter of propodeal spiracle. Petiole ca. 1. 7 times as long as postpetiole; petiolar node in posterior view weakly emarginate at apex. Postpetiole 1.7 times as broad as petiolar node. Frons longitudinally rugose, with interspaces smooth and shining; dorsal face of occipital lobe reticulate, with enclosures punctured slightly but shining; narrow area below frontal carina weakly punctured; lateral face of head behind eye weakly rogoso-reticulate and weakly shining; dorsal face of promesonotum rugosoreticulate, with very weakly punctured enclosures; lateral face of promesonotum largely smooth and shining; the remainder of alitrunk, and petiole and postpetiole weakly punctured and dull; gaster smooth and shining.

Type Material

Eguchi (2001) - Major; type locality: Siboga, Sumatra. One syntype (major, Museo Civico di Storia Naturale, Genoa) was examined, and is designated as the lectotype.
