Description

Worker

Eguchi 2001. Fig. 7. Lectotype and paralectotype of Pheidole inscrobiculatus Viehmeyer: A, major, head in full-face; B, same, head in profile; C, same, alitrunk and waist in profile; D, minor, head in full-face view; E, same, alitrunk and waist in profile.


Eguchi (2001) - Major (lectotype). Measurements: TL 2.9 mm; HL 1.22 mm; HW 1.02 mm; 5L 0.51 mm; FL 0.73 mm; CI 84; 51 50; FI 72. Head broadest at about midlength of head (Fig. 7 A), in profile slightly impressed on vertex (Fig. 7B); anteroventral margin of cranium bearing 3 median processes (median one smallest). Clypeus without a median longitudinal carina. Eye situated at about 1/3 distance of head (from anterior margin of clypeus to posterior margin of occipital lobe). Frontal carina and antennal scrobe only present around antennal insertion. Antenna with a 3-segmented club; scape reaching about midlength of head; terminal segment 1.3 times as long as preceding two segments together. Masticatory margin of mandible with apical and preapical teeth, and a distinct denticle in front of basal angle. Promesonotum forming a high dome, in profile (Fig. 7C) with a slight prominence on its posterior declivity; dorsal portion of the dome weakly produced laterally. Mesopleuron without a transverse impression. Propodeal spine triangular, ca. 2.5 times as long as diameter of propodeal spiracle. Petiole ca. 2 times as long as postpetiole (excluding helcium); petiolar node in posterior view hardly emarginate at apex. Postpetiole ca. 1.8 times as broad as petiolar node. Frons longitudinally rugose; dorsal and dorsolateral faces of occipital lobe reticulate, with very weakly punctured enclosures; dorsum of promesonotal dome very weakly punctured with several weak rugae; lateral face of the dome largely smooth and shining; the remainder of alitrunk, and waist and first gastral tergite weakly punctured.

Minor (paralectotype). Measurements: TL 1.6 mm; HL 0.52 mm; HW 0.48 mm; SL 0.50 mm; AL 0.74 mm; FL 0.57 mm; CI 91; SI 105; R 119. Head in full-face view slightly concave posteriorly (Fig. 7D); occipital carina weak. Clypeus without a median longitudinal carina. Eye situated just in front of midlength of head. Frontal carina and antennal scrobe present only around antennal insertion. Antenna with 3-segmented club; in full-face view scape extending beyond posterior border of head by a little more than its 1/6 length; terminal segment ca. 1.1 times as long as preceding two segments together. Promesonotum in profile convex, without any prominence on its posterior declivity (Fig. 7E). Mesopleuron without a distinct transverse impression. Propodeal spine ca. 2.5 times as long as diameter of propodeal spiracle. Petiole 1. 7 times as long as postpetiole (excluding helcium). Postpetiole in dorsal view subhexagonal, 1.6 times as broad as petiolar node. Head and promesonotum smooth and shining; the remainder of alitrunk weakly punctured at least partly; petiolar pedicel weakly punctured laterally; the remainder of petiole, and postpetiole and gaster smooth and shining.

Type Material

Eguchi (2001b) - Gunong Angsi, Malacca. Two syntypes (1 major and 1 minor Berlin Museum für Naturkunde der Humboldt-Universität) were examined, of which the major is designated as the lectotype.
