Type material.

Lectotype, of undetermined sex, hereby designated: “Brasil” / "coll. J.Schmidt" / " Phelister notandus Schm." / “Type” / " Lectotype Phelister notandus Schmidt, 1893, M.S.Caterino & A.K.Tishechkin des. 2010 (ZMHB).

Diagnostic description.

Length: "3 mm" ( Schmidt 1893b). Body rounded, slightly elongate, widest behind humeri, rufescent, with rather dense and conspicuous ground punctation; frons broad, depressed at middle; supraorbital stria absent; frontal stria strongly recurved at middle briefly interrupted; labrum shallowly emarginate at apex; prescutellar impression weakly impressed, narrower than scutellum; pronotal disk with few lateral secondary punctures; median pronotal gland openings annulate, ~ 4/5 behind anterior margin; marginal pronotal stria complete along sides and front; submarginal stria absent; elytral striae very reduced, crowded to side; outer subhumeral stria interrupted but present at base and apex; inner subhumeral present in apical 2/3; striae one and two complete; stria three present at base only; 4th, 5th and sutural striae absent except for basal arch; propygidium large, as long along midline as pygidium, with dense ground punctation and only slightly larger secondary punctures interspersed; pygidium largely lacking secondary punctures; prosternal keel emarginate at base, striae convergent to apex; prosternal lobe short, with fine marginal striae; mesoventrite produced, with complete marginal stria continued at sides by postmesocoxal stria, which ends freely at middle of lateral portion of metaventrite; mesometaventral stria sinuate at middle, reaching nearly to mesoventral stria, continued at sides by lateral metaventral stria toward metepipleuron; abdominal ventrites obscured by point; all tibiae slightly broadened; protibia strongly dentate, with ~ five marginal spines; spines of meso- and metatibiae weak, most confined to distal 1/2.

Distribution.

This species is only known from the type, with only the unfortunately vague location “Brasil”.

Remarks.

Despite not being able to examine male genitalia for this species, its placement in this subgroup seems secure. It is a rather autapomorphic species, yet showing moderate development of some characters that are more extremely expressed in some of the following species, including dense punctation and expanded tibiae. It is hoped that additional material of this species is discovered to allow us to more comprehensively evaluate its relationships, and to pinpoint its geographic range.
