Diagnostic description.

Length: 1.50-1.65 mm (avg. 1.62 mm); width: 1.22-1.42 mm (avg. 1.36 mm). Body small, elongate oval, convex, rufescent, with ground punctation moderately conspicuous; frons and epistoma somewhat narrow, deeply depressed along midline, sparsely but conspicuously punctate; supraorbital stria present, narrowly separated from sides of frontal stria, which is complete across depression; epistoma raised at sides; labrum emarginate and subcarinate apically; mandibles lacking conspicuous basal teeth; antennal club elongate with conspicuous setose patch on dorsal surface; prescutellar impression of pronotum ovoid to weakly acuminate at front, approximately equal in width to scutellum; pronotal disk with conspicuous secondary punctures in lateral thirds, more densely to front; median pronotal gland openings distinctly annulate, ~ 1/5 behind anterior margin; marginal pronotal stria complete laterally, broken with inner ends recurved briefly behind eyes; submarginal pronotal stria in apical 1/2 only, weakly impressed, crenulate, just turning anterior corner; elytron with single, complete epipleural stria; outer subhumeral stria present in apical one-third only, inner absent; dorsal striae 1-4 complete, 4th arched to sutural, 5th present in apical 1/2, sutural stria present in apical 2/3; propygidium with dense secondary punctures, those of pygidium smaller and sparser; prosternal keel emarginate at base, striae united along base, enclosing a triangle ~ 3/4 length of keel, with secondary striae along basal 1/2; prosternal lobe short, rounded, with complete marginal stria; mesoventrite produced, with complete marginal stria continued at sides by postmesocoxal stria, which ends freely at middle of lateral portion of metaventrite; mesometaventral stria angulate at middle, reaching middle of mesoventrite, continued at sides by lateral metaventral stria to middle of metacoxa; middle portion of metaventrite impunctate; 1st abdominal ventrite with secondary punctures along anterior margin, with incomplete lateral stria along inner margin of metacoxa; protibia with outer margin rounded, weakly dentate, with five or six marginal spines; meso- and metatibiae slender, mesotibia with rather robust marginal spines, those of metatibia fine and restricted to apical one-third. Male: basal piece ~ 1/3 length of tegmen; tegmen with sides evenly rounded, apices slightly separated, weak medioventral process present in basal 1/3; median lobe ~ 1/2 tegmen length, basal apodemes thin.

Distribution.

This species is most commonly found in northeastern South America, including Pará, Brazil, French Guiana, and Suriname. We have also seen specimens from Peru, but surprisingly not Ecuador.

Remarks.

Among the species treated here, P. blairi is best recognized by its small body size, median pronotal gland openings located close to anterior pronotal margin (Fig. 3A ), broken anterior marginal pronotal stria, and posteriorly obsolete lateral submarginal pronotal stria. It also has a relatively small area (shortened) enclosed by its prosternal keel striae. Phelister blairoides (#56, below) has similarly anterior pronotal gland openings, but has the lateral submarginal pronotal stria complete, and has the outer subhumeral elytral stria present basally as well as apically (though interrupted at middle). Phelister blairoides is also ~ 2 × as large. Although both these species are widespread and somewhat variable across their ranges, these differences are consistent. This species is also very similar to the following, P. erwini , differing principally by the more anteriorly located pronotal gland openings.

Most specimens have been collected by flight interception traps, with a few taken in carrion and dung baited pitfalls.
