Platyceroides pampinatus new species : 6A, dorsal habitus; 6B, shape of sclerotized tip of flagellum; 6C, male genitalia, location of flagellum apex indicated with arrow. Platyceroides infernus new species : 7A, dorsal habitus; 7B, shape of sclerotized tip of flagellum of male genitalia. Description, holotype male. Length: 10.5 mm . Width: 4.5 mm . Color: Dark piceous, lighter piceous at margins; shagreened with weak brassy reflection. Head: Form narrow anteriorly, with gena not produced laterally as far as eye ( Fig. 6 A). Antennal club moderately small (distinctly shorter than funicle; about ½ length of scape); antennomeres of club entirely tomentose. Labrum relatively small, length subequal to width of distal maxillary palp. Mandibles falcate, externally rounded, internally with 1–2 indistinct teeth. Pronotum: Surface weakly shiny (minutely shagreened) with moderately deep punctures; punctures dense, separated by about 1 puncture diameter, median line impunctate. Form broad, explanate, lateral margins broadly rounded, posterior angle slightly <90°. Elytra: Surface weakly shiny (distinctly shagreened), with few transverse rugae, dinstinctly striate; striae moderately impressed with small punctures, intervals not strongly convex, with punctures finer, sparse, irregular. Wings: Wings fully developed. Legs: Mesotibiae and metatibiae robust (not slender). Abdomen: Male genitalia with permanently everted internal sac sclerotized, elongate, with triangularly expanded apex; apex in distal view with leaf-like, strongly sclerotized plate; plate rounded with acute apex ( Fig. 6 B). Description, allotype female. Length: 10.2 mm . Width: 4.5 mm . Color uniformly dark reddish brown. Differs from male holotype in the following characters. Head: Antennal club small, shorter than length of funicle, antennomeres of club partially glabrous. Mandibles falcate, externally rounded, with basal tooth weakly indicated. Pronotum: Form broader. Elytra: Form less elongate, suboval. Surface with distinct, transverse rugae; distinctly striate on disc; intervals with finer, irregular punctures. Wings: Wings atrophied. Legs: All tibiae distinctly broader, more robust than in male. Variation in paratypes . Males ( n = 122): Length: 9.0– 11.9 mm . Width: 3.8–4.7 mm . Female paratypes ( n = 46): Length: 9.5–11.9 mm .

The name is derived from the Latin pampinatus , meaning having tendrils and vine leaves, and is used as an adjective in the nominative singular. This is with respect to the leaf-shaped sclerite at the apex of the tendril-like flagellum of the male genitalia. Remarks. This species is one that was frequently misidentified as P. agassii in all collections, and it is relatively well represented in collections. Surprisingly, paratype specimens of P. pampinatus from a single collecting event were identified in the Angell collection (ANSP) as three different species. As with the males, females of this species possess relatively small antennal clubs.
