( Fig. 10–12 , 24 , 30 )

Caraphia lingafelteri Ohbayashi and Yamasako, 2016: 210 , 213; Monné 2018: 5 (cat.).

Noctileptura squamosa: Maes et al. 2010: 12 (distr.), misidentified.

Description of female. Integument mostly dark brown; mouthparts reddish-brown, with some areas yellowish-brown; distal area of clypeus and labrum yellowish-brown; posterior area of gulamentum reddish-brown.

Head. Frons densely, moderately finely, shallowly punctate; with short abundant, narrow yellowishbrown scales. Vertex finely punctate between antennal tubercles and upper eye lobes, slightly, gradually coarser toward prothoracic margin; with moderately short (longer than on frons), abundant, narrow yellowish-brown scales except glabrous, longitudinal central area. Area behind upper eye lobes with sculpturing and scales as on vertex; with a few long, erect brownish setae close to eye. Area behind lower eye lobes coarsely, densely punctate in wide area close to eye, finer, distinctly sparser in narrow area close to prothorax; with moderately short yellowish-brown scales in coarse punctate area, glabrous on remaining surface. Antennal tubercles with sculpturing and scales as on frons except glabrous and smooth narrow distal area. Median groove distinct from clypeus to level of posterior margin of eyes, deeper between antennal tubercles and upper eye lobes. Genae finely, moderately abundantly punctate; with short, narrow, moderately abundant yellowish-brown scales, distinctly more slender than in area behind eyes. Gulamentum smooth, glabrous posteriorly, moderately coarsely, shallowly, abundantly punctate, with narrow, short, sparse scales in wide anterior area (scales yellowish-brown anteriorly, gradually whitish posteriorly). Postclypeus with sculpturing as on frons; scales as on frons posteriorly, gradually sparser and narrower toward anterior margin; with a few long, erect yellowish-brown setae laterally near anterior margin. Labrum coplanar with clypeus in posterior half, inclined in anterior half; finely punctate posteriorly close to inclined area, smooth on remaining surface; with minute, moderately sparse yellowish setae, interspersed with long, erect yellowish-brown setae. Distance between upper eye lobes 0.78 times length of scape; in frontal view, distance between lower eye lobes 1.06 times length of scape. Antennae 1.45 times elytral length, reaching elytral apex at basal third of antennomere XI; scape moderately coarsely, abundantly punctate, with narrow, short, decumbent, abundant yellowish scales; antennomeres III–V with short, decumbent, abundant, thick yellowish setae (more abundant, scale-shaped on III–IV); remaining antennomeres with whitish pubescence; outer side of antennomeres III–IV not carinate; outer side of antennomere V–VI carinate at distal third; outer side of remaining antennomeres entirely carinate. Antennal formula (ratio) based on length of antennomere III: scape = 0.84; pedicel = 0.24; IV = 0.89; V = 1.08; VI = 0.89; VII = 0.89; VIII = 0.81; IX = 0.81; X = 0.76; XI = 0.89.

Thorax. Prothorax about as long as wide; sides slightly divergent from posterolateral angles to about midlength, then convergent toward distinct anterior constriction. Pronotum coarsely, abundantly punctate; with moderately short, abundant, slightly arched yellowish-brown scales (some of them lighter). Sides of prothorax with sculpturing and scales as on pronotum. Prosternum moderately coarsely and abundantly punctate; with short, arched, moderately sparse yellowish scales (more abundant and whiter in posterior half, especially close to procoxal cavities), except nearly glabrous area near anterior margin; with very short yellowish scales close to anterior margin; postcoxal processes nearly glabrous. Prosternal process with short, narrow, decumbent, moderately sparse whitish scales. Ventral surface of mesothorax with short, decumbent, narrow, abundant yellowish-white scales (whiter depending on light intensity), slightly sparser on mesepimeron. Ventral surface of metathorax with short, decumbent, narrow, abundant yellowish-white scales (whiter depending on light intensity), distinctly denser on metanepisternum and sides of metaventrite, absent along central discrimen. Scutellum with very short, decumbent, narrow yellowish scales, except glabrous area close to margin. Elytra. Coarsely, deeply, moderately abundantly punctate in basal half (punctures not aligned in rows, nearly 8-shaped), gradually finer, sparser toward apex; with narrow, long, arched yellowish-brown setae not aligned in rows ( Fig. 10 , 30 ); with longitudinal row of short, narrow yellowish scales along sutural and epipleural margins; with minute yellowish seta in nearly all punctures. Legs. Femora and tibiae with short, abundant, decumbent yellowish scales (whiter depending on light intensity); tibiae interspersed with fine yellowish setae ventrally in distal half.

Abdomen. Ventrites finely, moderately abundantly punctate; with short, decumbent, abundant yellow- ish scales (whiter depending on light intensity), interspersed with long, erect yellowish setae laterally; apex of ventrite V truncate.

Variation (observed in males and females). Body mostly reddish-brown, including legs and antennae; abdominal ventrites partially dark reddish-brown; antennae, legs, most of elytra, and parts of ventral surface reddish-brown; scales on vertex and behind eyes distinctly short and sparse; scales on scape very short and sparser; prothorax slightly longer than wide; scales on ventral surface of thorax distinctly short and sparse.

Dimensions (mm), males/females. Total length 9.35–11.60/11.65–15.50; prothoracic length 1.60–2.00/2.00–2.60; anterior prothoracic width 1.05–1.40/1.30–1.80; posterior prothoracic width 1.40–1.90/1.90–2.50; prothoracic width about central area 1.50–2.05/1.95–2.65; humeral width 2.45– 3.30/3.35–4.20; elytral length 5.85–7.50/7.75–10.20.

Remarks. Males differ by longer antennae, 1.7 times elytral length, reaching elytral apex in basal distal third of antennomere X. According to Ohbayashi and Yamasako (2016) the elytral apex is not truncate but is roundly narrowed to sutural angle. However, based on the larger number of specimens available for study, it can also be obliquely truncate.
