( Figures 57–65 )

Temnopis nigripes ; Martins 1978b: 131; 1997: 84; Martins and Galileo 2004: 12, 68; Monné et al. 2010: 242 (distr.). (misidentification)

Description. Holotype male. ( Figures 57–62 ) Head capsule (except dark-brown median groove), antennae, prothorax, and ventral surface of mesothorax orangish brown; mandibles orangish brown on about basal half, black apically; ventral surface of metathorax and abdominal ventrites yellowish brown, except pale apex of abdominal ventrites I–IV; scutellum orangish brown; elytra orangish brown on basal quarter, gradually yellowish brown towards apex; coxae and trochanters yellowish brown, gradually lighter towards hindlegs; profemora yellowish brown except brownish apex; meso- and metafemora orangish brown basally, gradually dark brown towards apex (darker area larger dorsally); tibiae dark brown; tarsomeres I–II dark brown, and tarsomeres III–V orangish brown.

Head. Frons, vertex, and area behind upper eye lobes rugose-punctate; with sparse, short, bristly yellowish setae. Area behind region of connection between eye lobes and behind lower eye lobes rugose; with sparse, short, bristly yellowish setae. Genae small, triangular, almost glabrous. Wide central area of clypeus with sculpturing and setae as on frons, sides glabrous. Labrum subcoplanar with clypeus posteriorly, inclined, concave anteriorly; with sparse, long, erect yellowish setae on sides of posterior area, moderately abundant, short erect yellowish setae anteriorly. Gulamentum longitudinally sulcate centrally on posterior half; posterior 3/4 sparsely, finely punctate, with transverse, very fine striae; anterior quarter densely, very finely transversely striate; posterior quarter and central area of posterior quarter glabrous; remaining surface with sparse, short yellowish setae (more abundant on anterior quarter), and long, erect setae of same colour interspersed on anterior quarter. Upper eye lobes wide, closer to each other than width of one upper lobe ( Figure 57 ); area of connection between eye lobes ( Figure 62 ) smooth, narrow, black, distinctly shorter than width of upper eye lobe; distance between lower eye lobes 0.43 times distance between outer margins of eyes. Antennae 2.1 times elytral length, reaching elytral apex at posterior quarter of antennomere VI. Scape slightly widened towards apex (posterior diameter 1.4 times wider than basal diameter); rugose, with somewhat abundant asperities (asperities dark dorsally and laterally); with sparse, bristly yellowish setae, and long, erect setae of same colour interspersed. Antennomeres III–V tumid, rugose, with somewhat abundant asperities, slightly larger, darker ventrally on III and IV; antennomere V distinctly and gradually narrowed from middle to apex; III–V with short, erect, somewhat sparse yellowish setae dorsally and laterally, longer ventrally. Antennomeres VI–XI with yellowish-white pubescence, denser towards XI, shorter, erect setae of same colour interspersed dorsally and laterally, and longer, erect setae of same colour ventrally and dorsal apex of VI–X. Antennal formula based on length of antennomere III: scape = 0.44; pedicel = 0.06; IV = 1.10; V = 0.82; VI = 0.62; VII = 0.54; VIII = 0.46; IX = 0.42; X = 0.42; XI = 0.46.

Thorax. Prothorax about as long as wide; sides uniformly rounded, widened from anterolateral angles to posterior fifth, then strongly narrowed towards posterolateral angles; without spicule or spine. Pronotum transversely, somewhat widely sulcate close to anterior margin, and longitudinally somewhat widely sulcate centrally, from anterior transverse sulcus to posterior constriction; surface between anterior sulcus and posterior constriction densely, microscopically punctate, slightly rugose, with sparse, fine punctures interspersed; central area of posterior constriction with oblique, smooth tubercle on each side (tubercles divergent from posterior margin of pronotum), and narrow carina between them; sides of posterior constriction rugose; with somewhat sparse, short, decumbent yellowish setae, except glabrous central area of posterior constriction. Sides of prothorax with sculpturing and setae as on central area of pronotum. Prosternum sparsely, finely punctate; posterior 2/3 finely, transversely striate; with sparse, somewhat short, bristly yellowish setae, and long, erect setae of same colour interspersed. Prosternal process laminiform except posterior third slightly widened, placed below level of prosternum, surpassing apex of procoxae. Mesoventrite with somewhat abundant, short, decumbent yellowish setae laterally, not obscuring integument, sparser centrally. Mesoventral process triangular basally, becoming laminiform posteriorly, not reaching apex of mesocoxae. Metanepisternum and sides of metaventrite with somewhat abundant, short, decumbent yellowish setae; central area of metaventrite almost glabrous. Scutellum smooth, nearly glabrous. Elytra. Surface somewhat rugose, finely punctate; with longitudinal, slightly elevated dorsal carina, from near base to near apex; with somewhat abundant, short, decumbent yellowish setae; apex narrowly, individually rounded. Legs. Femora with sparse, short, decumbent yellowish setae; tibiae with somewhat abundant, short, bristly golden setae, except entire ventral surface of protibiae with dense yellowish-brown pubescence, and posterior ventral area of meso- and metatibiae with dense golden setae. Metatarsomere I twice length of II–III together.

Abdomen. Ventrites with somewhat long, decumbent, sparse yellowish setae, sparser centrally. Apex of ventrite V widely, slightly rounded.

Female. ( Figures 63–65 ). Differs from male by the antennae 1.6 times elytral length, reaching elytral apex at apex of antennomere VIII, antennomeres III–V not tumid, and apex of abdominal ventrite V somewhat narrow and truncate.

Chromatic variation (males and females). Head capsule and basal antennomeres light orangish (sometimes, basal antennomeres somewhat brownish; more rarely, antennae almost entirely dark brown); pronotum light orangish; ventral surface of thorax from light yellow to mostly dark orangish brown with yellowish irregular areas interspersed; elytra orangish brown only on basal quarter; meso- and metafemora yellowish only basally, mostly dark brown or blackish on remaining surface (sometimes, almost entirely blackish; tibiae brown (somewhat dark orangish brown depending on light intensity).

Morphological variation. Sides of prothorax with spicule close to posterior constriction in one male examined.

Dimensions (mm) (holotype male/male paratypes /female paratypes). Total length, 9.35/7.00–9.55/9.90–10.50; prothoracic length, 1.50/1.05–1.50/1.20–1.30; anterior prothoracic width, 1.20/1.05–1.15/1.05–1.15; posterior prothoracic width, 1.20/0.95– 1.20/1.20–1.30; maximum prothoracic width, 1.50/1.25–1.50/1.40–1.55; humeral width, 1.75/1.35–1.75/1.90–2.00; elytral length, 6.45/4.75–6.60/7.10–7.50.

Type material. Holotype male from BRAZIL, Pernambuco: Estação Experimental de Itapirema (Goiana), 15.VI.1976, R. Moura leg. ( MZSP _54748) . Paratypes – 2 males ( MZSP _54749; MZSP _54750), 2 females ( MZSP _54751; MZSP _54752), same data as holotype . Amazonas: Parintins, 1 male, XI.1939, no collector indicated ( MZSP _54753).

Etymology. Latin, ′ignotus̍ (unknown; adjective); alluding to the fact that the identity of the species had remained unknown.

Remarks. Temnopis ignota sp. n. is similar to T. jolyi Martins, 1978 (see photograph on Bezark 2023a), but differs by the meso- and metafemora pedunculate-clavate (femoral club wide) ( Figures 58, 64 ), while in T. jolyi , they are subcylindrical (femoral club slightly widened).
