Diagnostic description.

Length: 1.81-2.01 mm (avg. 1.90 mm); width: 1.38-1.58 mm (avg. 1.47 mm). Body quite elongate, weakly rounded to almost parallel-sided, rufescent, with moderately conspicuous ground punctation throughout; frons broad, distinctly punctate, depressed along midline; supraorbital stria present for middle-3/4, abbreviated at sides; frontal stria interrupted at sides, present within median depression; epistoma weakly depressed; labrum smooth, flat emarginate; mandibles lacking basal teeth; prescutellar impression forming semi-circle ~ 2.5 × width of scutellum; median pronotal gland openings rather obscure among dense ground punctation, located within small impunctate areas ~ 2/3 behind anterior pronotal margin, not annulate; pronotal disk with secondary punctures only slightly larger than ground punctation, intermingled more densely from middle to lateral margin; marginal pronotal stria complete along lateral and anterior margins, crenulate at front; elytron with single, complete epipleural stria; outer subhumeral stria complete, inner absent; dorsal striae 1-4 complete, 4th arched to suture, 5th stria present in apical 2/3, sutural stria in apical 3/4; pygidia with moderately coarse secondary punctation, slightly sparser posterad; prosternal keel emarginate at base, striae separate at base, converging, united near apex; prosternal lobe weakly reflexed, rather narrow, with marginal stria complete; mesoventrite narrowly produced, with complete marginal stria continued by postmesocoxal stria nearly to base of metepisternum; mesometaventral stria bluntly angulate at middle, weakly crenulate, reaching middle of mesoventrite, continued at sides by lateral metaventral stria, reaching inner 1/3 of metacoxa; 1st abdominal ventrite with single, complete lateral stria, bent posterad at inner posterior corner of metacoxa; middle of ventrites with only sparse ground punctation; protibia with outer margin somewhat rounded, weakly dentate, with six or seven marginal spines; mesotibia slightly broadened, with five or six long marginal spines; metatibia more slender, with two or three fine spines limited to apical 1/2. Male: basal piece ~ 1/3 length of tegmen; tegmen narrow, with sides widening toward apical fourth, then narrowed to bluntly rounded apices; tegmen rather thick, bent near base in lateral view; medioventral process absent; median lobe ~ 1/2 tegmen length, basal apodemes abruptly thinner near bases.

Etymology.

This species name refers to the mixed, or ‘miscellaneous,’ small and large punctures on the dorsum.

Distribution.

This species is known from southern Peru and south-central Brazil.

Remarks.

Phelister is distinctive in a several features, especially its elongate body form, doubled pronotal punctation, broad prescutellar impression, and complete lack of lateral submarginal pronotal stria. Its apical three protibial marginal spines also form a distinctly larger set than those closer to the base.
