description: Panopides riedeli Setliff, new species   
(Figs. 10–11; 14; 37–45)  
 Diagnosis. Elytral interval 3 strongly elevated with broadened prominence, mesofemur not exceeding the elytral apex, and straight male protibia lacking a setal brush best serve to distinguish this new species from P. anticus and P. philippinicus. This distinctive species is also somewhat smaller than its congeners (6.2–6.4 mm compared to 6.8–9.0 mm), has distally carinate coxae, the middle and hind coxae closer together, tergite VIII broader than long, the aedeagus more curved and its apex more produced and acuminate, and the basal pair of endophallic sclerites are much more slender and elongate.   
 Description. Length 6.2–6.4 mm, width 2.5–2.8 mm (n 5 3). Vestiture primarily comprised of small, dark brown squamae, with oblong median macula of paler brown at base of pronotum and indistinct light brown patches at elytral humeri. Decumbent scales originating from granules on dorsum dark brown. Head. Male rostrum as long as pronotum, straight for basal two-thirds, moderately arcuate in apical third. Antennae inserted beyond middle of rostrum, club broadest subapically, subequal in length to funicular articles 1 + 2 (Fig. 44). Thorax. Pronotum as broad as long; fine medial carina obsolescent, remnant visible only at anterior margin. Scutellum ovate, larger than adjacent elytral punctures. Basal transverse row of marginal elytral punctures very deep and elongate; interspace between elytral punctures generally greater than diameter of puncture. Intervals strongly convex, coarsely granulate. Interval 3 with well developed longitudinal prominence starting near base and terminating at elytral declivity; prominence distinctly elevated above all other intervals, broad, obscuring adjacent striae, with rounded apex and four rows of closely appressed, shiny granules. Interval 5 also elevated slightly above adjacent intervals, but to much lesser extent than interval 3 (best observed in caudal view). Meso- and metacoxae separated by about one-half length of mesocoxa. Distal margin of coxae distinctly carinate, forming ridge along coxal margin with trochanter (Fig. 43). Male protibia straight, lacking setal brush on ventral margin (Fig. 14). Hind femur longer than elytral apices, mesofemur reaching but not exceeding elytral apices. Abdomen. Posterior margin of male tergite VII truncate, weakly emarginate medially, 10–11 pairs of plectral tubercles arranged in 2 oblique, glabrous, longitudinal rows on either side of midline, reaching posterior margin (Fig. 41). Intercoxal process of ventrite 1 coarsely punctate (Fig. 43). Male terminalia. Tergite VIII subquadrate, broader than long, posterior margin truncate. Sternite VIII obsolescent (Fig. 37). 96 at trochanter; 44) antenna; 45) meso- and metapleura, lateral view. Scale line 5 1.0 mm.   
Spiculum gastrale with apodeme subequal in length to aedeagal apodemes; apical arms well developed, broad, more or less symmetrical (Fig. 40). Tegminal apodeme shorter than width of tegminal ring (Fig. 42). Aedeagal body one-third as long as apodemes, somewhat curved, with apex produced, acuminate, and abruptly bent, subapically setose on dorsum. Paired, small elongate-oval sclerites near middle of aedeagal body. Endophallus with inverted Y-shaped apical sclerite and pair of very slender elongate basal sclerites, subequal in length to aedeagal apodemes (Figs. 38–39). Female of this species is unknown.  
 Remarks. As discussed above, this new species is morphologically distinct from the two other known species of the genus, however, it shares the putative synapomorphies of the genus.   
 Distribution. Central Sulawesi   
 Material examined. Holotype: Oi, ‘‘C-Sulawesi Palu Palolo Lindu -N.P. leg. A. Riedel 25–27. viii. 1990 ’’ (MZB); Paratypes: 2 Oi, with the same label data as the holotype (1 ARC; 1 SMNK).   
 Etymology. The specific epithet is a patronym honoring Dr. Alexander Riedel, collector of the specimens of the new species, in recognition of his significant contribution to the study of weevils in the Indo-Australian region.
