TYPE MATERIAL: Holotype, Ƌ in CMNC labeled ‘‘N. CAR:Wilkes Co. Jeffress Park, 3500̍ BlueRidgePkwy, mi 272 17.VIII.1981 S. Peck log—leaf litter/ HOLOTYPE Agathidium framea Miller and Wheeler, 2003 [red label with black line border]’’.
TYPE LOCALITY: United States, North Carolina, Wilkes Co., Jeffress Park, Blue Ridge Parkway mi 272, 3500̍.
DIAGNOSIS: This species is distinguishable from most species by the relatively reduced eyes (dorsoventrally compressed and large faceted), relatively indistinct oblique metasternal carinae which meet medially in a very small, indistinct triangle, unmodified gula, the male with a distinct, broad lobe along posterior margin of coxa (fig. 117), and very distinctive male genitalia. The apical portion of the median lobe is long and apically expanded into an arrowhead shape in ventral aspect (fig. 311).
DESCRIPTION: Body small (TBL = 1.93– 2.12 mm), rounded (PNW/TBL = 0.4), robust, strongly contractile.
Head, pronotum, and elytra red; venter yellow to yellowbrown; antennae, palpi, and legs yellow.
Head broad (MDL/OHW = 0.52), dorsal surface flattened, dorsoventrally compressed; with very fine punctures, each with a short, very fine seta, surface between punctures shiny, very finely microreticulate; frontoclypeal suture obsolete medially; eyes strongly compressed, reduced to elongate triangle; gula broad, flattened, with prominent rim; antennomere ratios: length I:II:III = 1.8:1.0: 1.3, width VII:VIII:IX = 1.0:1.0:1.6. Pronotum very large, broad (PNL/PNW = 0.73– 0.75), strongly convex, anterolateral lobes strongly produced, lateral margin broadly curved, not angulate; with very fine, sparse punctures, each with a short, very fine seta, surface between punctures slightly microreticulate. Elytra broad, lateral margins strongly rounded, apically rounded (SEL/ELW = 1.02–1.06); punctation similar to pronotum; sutural stria indistinctly present only apically. Flight wings strongly reduced. Mesosternum broad, broadly convex; medial carina present, well developed. Metasternum narrow (MTL/MTW = 0.09–0.10), medially concave, slightly sloping dorsad anteriorly; oblique femoral carinae present, low and indistinct, meeting medially in small, triangular, posteriorly directed flange.
Male tarsi 554; pro and mesobasotarsomeres moderately laterally expanded, with moderately large field of ventral spatulate setae; mandibles not modified; metafemur broad, with exceptionally large, flat, triangular tooth subapically on posterior margin (fig. 117); metasternal fovea large, transverse, broadly oval with large, conspicuous brush of fine, dense setae; posteromedial margin of metacoxa with broad, flat, rounded

lobe. Median lobe in lateral aspect slender, strongly curved basally, moderately straight thereafter, apical portion slender, tapered, apex sharply and abruptly bent dorsad, apex pointed and often slightly recurved (fig. 312); in ventral aspect slender, long, lateral margins subparallel to sinuate, apical portion tapered, apically expanded into broad, arrowhead shape, apex rounded to medially point ed (fig. 311); operculum divided into two long, slender, straight rami, rami sometimes slightly apically expanded, apices pointed; endophallic armature consisting of long, flat, broad medial lobe that is apically truncate and slightly emarginate medially and lateral hyaline lobes on each side of median lobe (fig. 311); lateral lobes long, slender, apically slightly expanded, basally, along with basal piece, strongly sinuate in ventral aspect (fig. 313).
Female tarsi 544.
ETYMOLOGY: This species is named from the Latin word framea , meaning ‘‘spear’’, for the spearshaped apex of the median lobe of the aedeagus in this species.
DISTRIBUTION: This species has been collected from Georgia, North Carolina, Tennessee, and Virginia (fig. 373).

TYPE MATERIAL: Holotype, Ƌ in CMNC labeled ‘‘VA: Wise Co 1.5 mi S. Norton [handwritten]/rot. stump S. Peck, ber 133 1500̍ [handwritten]/ HOLOTYPE Agathidium appalachium Miller and Wheeler, 2003 [red label with black line border]’’. Only a single specimen is known of this species.
TYPE LOCALITY: United States, Virginia, Wise Co., 1.5 mi S Norton.
DIAGNOSIS: This species can be distinguished from most species by its very small size, reduced eyes, lack of a medial lobe on the anterior margin of the gula, relatively large metafemoral tooth (fig. 159), and distinctive median lobe which has the apex truncate in ventral aspect and the operculum relatively short (fig. 314).
DESCRIPTION: Body minute (TBL = 1.89 mm), oblong (PNW/TBL = 0.51), strongly contractile.
Head and pronotum light red; elytra red, not iridescent; venter yellowred; antennae, palpi, and legs yellow.
Head broad (MDL/OHW = 0.55), dorsal surface flattened, dorsoventrally compressed; with extremely fine punctures, surface between punctures shiny, smooth; frontoclypeal suture obsolete medially; eyes reduced, dorsoventrally compressed, and elongate, large faceted; gula slightly concave, unmodified; antennomere ratios: length I:II:III = 1.2:1.0: 0.9, width VII:VIII:IX = 1.1:1.0:2.1. Pronotum very large (PNL/PNW = 0.71), broad, strongly convex, anterolateral lobes strongly produced, lateral margin broadly curved, not angulate; with minute, sparse punctures, each with a short, very fine seta, surface between punctures smooth. Elytra broad, lateral margins strongly rounded, slightly elongate, but not apically acuminate (SEL/ELW = 0.97); punctation similar to pronotum; sutural stria absent. Flight wings strongly reduced. Mesosternum broad, rounded; medial carina well developed. Metasternum very narrow medially (MTL/MTW = 0.16), flattened, medially strongly dorsally sloped anteriorly; oblique femoral carinae present and distinct, meeting medially in rounded flange.
Male tarsi 554; pro and mesobasotarsomeres slightly laterally expanded, with small field of ventral spatulate setae; mandibles not modified; metafemur moderately broad, with strongly produced, flattened, thornlike subapical tooth on posterior margin (fig. 159); metasternal fovea prominent, transversely ovoid, with pencil of long, fine, dense setae. Median lobe in lateral aspect slender, slightly curved basally, straight thereafter, apical portion slender, apically distinctly curved dorsad (fig. 315); in ventral aspect slender, slightly widened medially, apical portion long, slender, tapered to abruptly truncate apex (fig. 314); operculum moderately small, broadly Vshaped, each ramus very slender, apically narrowly rounded (fig. 314); lateral lobes moderately robust, in lateral aspect broad, apically tapered to narrowly rounded apex, without long subapical setae (fig. 316).
Female not examined.
ETYMOLOGY: Named after the Appalachian Mountains, where the type specimen was collected.
DISTRIBUTION: This species is known only from the type locality in Virginia (fig. 371).
DISCUSSION: The single specimen of this species was collected from a Berlese sample of a ‘‘rotten stump’’.
