Diagnostic description.

Length: 1.85-2.17 mm (avg. 2.01 mm); width: 1.50-1.77 mm (avg. 1.64 mm). Body subparallel-sided, weakly elongate, slightly flattened, rufescent, ground punctation of dorsum moderately fine; frons narrow, deeply impressed along midline; supraorbital stria fine, short, detached at sides; frontal stria deeply impressed along eyes, finely impressed at middle, complete; labrum weakly emarginate at apex; mandibles lacking basal teeth; antennal club elongate; prescutellar impression semicircular, ~ 2.5 × scutellar width; pronotum lacking secondary punctures in middle third, but with sparse (varied in density) secondary punctures laterad gland openings; median pronotal gland openings ~ 3/4 behind anterior margin, distinctly annulate; lateral submarginal pronotal stria complete, curved inward at front, weakly crenulate, disk depressed along its inner edge, marginal bead convex; elytron with single, complete epipleural stria; outer lateral subhumeral stria in apical 1/2 or less, inner absent; dorsal striae 1-4 complete, 4th arched to suture, 5th stria present in apical 1/2, sutural stria slightly longer; propygidium with small secondary punctures uniformly separated by about their diameters, those of pygidium slightly smaller and sparser; prosternal keel broad at base, striae widely separated at base, meeting 2/3 from base, keel abruptly narrowed anterad; prosternal lobe extremely short, with marginal stria; mesoventrite short, strongly projecting, marginal stria fine, continued at side by postmesocoxal stria to middle of lateral portion of metaventrite; mesometaventral stria bluntly angulate at middle, reaching middle of mesoventrite, lateral metaventral stria reaching middle of metacoxa; metaventrite impunctate; 1st abdominal ventrite with single row of secondary punctures along anterior margin; protibiae narrow, outer margin ‘scalloped’, with a close set series of fine incisions, each with a minute spine, the apical-most spine larger; protarsal setae of male not modified; mesotibia with rather dense series of fine marginal spines, those of metatibia fewer, sparser, and principally restricted to apical 1/2. Male: basal piece sp. nov. 1/4 length of tegmen; tegmen with sides subparallel in basal 2/3, narrowed to thin, blunt, slightly divergent apices; weakly curved, thickened at middle in lateral view; medioventral process absent; median lobe ~ 1/3 tegmen length, basal apodemes abruptly narrowed at basal 1/3.

Etymology.

This species name refers to the somewhat ‘serrate’ protibiae, shared with the very similar following species.

Remarks.

This species and the next one ( P. geminus ) share one very distinctive character, having what we’ve previously referred to as ‘scalloped’ protibial margins (Fig. 2G View Figure 2 ), with very small, closely set marginal spines and no development of marginal teeth. While unusual, a similar form of protibia also occurs in the P. umens subgroup, not obviously related to this one. Phelister serratus and P. geminus are also rather elongate, parallel-sided, and relatively impunctate, with depressed pronotal margins, a quite vertical head, and a narrow frons. These two species are, however, extremely similar, and difficult to distinguish, even in male genitalia. However, we feel that the differences we have observed are sufficiently marked and consistent to recognize them as distinct (see Fig. 7C, D View Figure 7 vs. 7E, F): P. serratus is narrower in body form, with the pronotal disk less strongly depressed along the inner edge of the lateral submarginal stria, has the median portion of the frontal stria attached to the lateral portions, and is generally more strongly punctate, both in ground punctation and in secondary pronotal punctures.

We have generated some DNA sequence data for individuals of each from the same (type) locality, and, while we have not successfully sequenced the barcoding gene for both, they are distinct in 18S sequence, which also supports the hypothesis that they are distinct. We have selected these respective DNA vouchers as the type specimens of each.

Central American specimens of P. serratus tend to show a few distinctive variants, but not consistently; often they have the prosternal keel less strongly narrowed toward the front, and the lateral epistomal ridges may appear striate. We considered separating these as distinct, but for now leave this as a widespread and variable species. In part for this reason, we have restricted the type series to a relatively small number of localities in eastern Ecuador and Colombia, and northern Peru.

Distribution.

This common and widespread species is known from Costa Rica southward to Bolivia, east to the Guianas and Amazonian Brazil, with one record from coastal Brazil ( Espírito Santo).
