Novantinoe noguerai Santos-Silva and Le Tirant , new species

( Figs. 8–11 )

Description. H o l o t y p e M a l e. H e a d d a r k brown, except for frons reddish brown, antennal tubercles reddish brown, gradually yellowish toward apex, clypeus reddish brown, labrum orange-brown, mouthparts orange-brown, ventral side yellowish brown on center of base, gradually reddish brown toward sides. Antennae orangebrown. Prothorax dark brown. Meso- and metathoracices dark brown, except for yellowish brown, narrow area on apex of mesosternal process, and area of metathorax close to metacoxae. Elytra dark reddish brown. Femoral peduncle yellowish; femoral club light reddish brown. Tibiae light reddish brown basally, yellowish on remaining surface of basal 2/3, slightly reddish on distal third. Tarsomeres I–II light reddish brown; tarsomeres III–V reddish brown. Head: Frons narrow, finely, moderately abundantly punctate laterally, smooth medially; with short, moderately abundant setae laterally, glabrous medially. Area between antennal tubercles and upper eye lobes smooth; with short, moderately abundant setae, except for narrow glabrous area close to eyes. Vertex moderately finely, very sparsely punctate laterally, distinctly denser, coarser close to margin of prothorax; with short, moderately abundant setae laterally, interspersed with some long setae near eyes, glabrous medially. Area behind eyes smooth on area closer to eyes, coarsely, abundantly punctate on area closer to prothorax (punctures gradually finer, sparser toward inferior side of lower eye lobe); with short, abundant setae on area closer to upper eye lobes, gradually sparser toward inferior side of lower eye lobes (except for pubescent, narrow band close to eye). Area between apex of eyes and gula with long, sparse setae. Area between base of lower eye lobes and submentum with short, moderately abundant setae. Submentum with long, sparse setae. Maxillary palpomere IV securiform. Distance between upper eye lobes 0.2 times length of scape; distance between lower eye lobes in ventral view 0.5 times length of scape; largest width of upper eye lobes slightly shorter than largest width of scape. Antennae as long as 2.2 times elytral length; reaching elytral apex at middle of antennomere VII. Scape without depression on base of dorsal surface; coarsely, abundantly punctate on basal half, gradually sparser toward apex; with short, sparse setae interspersed with long setae. Antennal formula based on antennomere III: scape = 0.92; pedicel = 0.13; IV = 1.05; V = 1.05; VI = 1.05; VII = 1.00; VIII = 0.92; IX = 0.92; X = 0.73; XI = 0.73. Thorax: Prothorax, including lateral tubercles, transverse, 1.2 times as wide as long; lateral tubercles large, conical. Pronotum with 5 tubercles: 2 large, not notably elevated, subrounded, placed on each side of anterior half; 2 smaller, subrounded, placed on each side of basal half; 1 elongate, placed medially. Pronotal surface shiny, smooth; with short, moderately abundant setae interspersed with some long setae (denser laterally on base), except for glabrous surface of central tubercle and inner side of lateral tubercles. Prosternum smooth, except for transverse, narrow sulcus medially; with short, sparse setae on basal half; with some short and long setae on anterior half. Metasternum microsculptured and finely, abundantly punctate laterally, gradually sparser, not microsculptured toward center; with short, abundant, decumbent setae laterally and anteriorly, gradually sparser toward center. Metepisterna with short, abundant, decumbent setae. Elytra with 6 rows of punctures: 1 close to suture, reaching about distal quarter (punctures finer, sparser toward apex); 3 between previous row and humerus (innermost not reaching middle of elytra); 1 laterally from humerus to beyond middle of elytra (central punctures notably coarse); 1 close to lateral margin, reaching about distal fifth (punctures finer, sparser toward apex). Elytral surface pubescent (pubescence distinctly not obscuring integument); apex spiniform (outer angle with distinct spine, sutural angle absent). Abdomen: Ventrites very finely, moderately abundantly punctate (almost indistinct on IV–V); with short, abundant, decumbent setae interspersed with some long setae; apex of ventrite V truncate. Legs: Profemur somewhat fusiform; with spiniform tubercles on distal half of ventral side of club; with short, sparse setae dorsally and laterally, distinctly denser ventrally. Meso- and metafemora slightly clavate; mesofemur with tubercles as on profemur, but sparser and less spiniform; apex rounded on both sides; with short, sparse setae.

Dimensions. Total length (including mandibles) 13.9 mm; prothoracic length 1.9 mm; anterior prothoracic width 1.5 mm; basal prothoracic width 1.7 mm; broadest prothoracic width 2.3 mm; humeral width 2.8 mm; elytral length 9.8 mm.

Type Material. Holotype male from MEXICO: Chiapas: El Rosario , 1,800 m, 2.VII.1995, Curoe and Hopkins col. ( MZSP).

Etymology. This new species is named after Felipe Arturo Noguera Martínez (Universidad Nacional Autónoma de México, Ciudad de México, DF, Mexico), for his contribution toward knowledge of Cerambycidae .

Remarks. Novantinoe noguerai is slightly similar to Novantinoe morrisi Santos-Silva and Hovore, 2007 , but differs as follows: scape thicker; elytra not darker on basal quarter; elytral apex not truncate. In N. morrisi (see photograph of the holotype at Bezark 2015), the scape is distinctly more slender, the elytra are darker basally, and the elytral apex is truncate. It is also somewhat similar to Elytrimitatrix (Grossifemora) fuscula (Bates, 1885) (a species that apparently belongs to Novantinoe ) (see photograph of a syntype at Bezark 2015), also from Mexico, but differs mainly by the lateral tubercles of the prothorax not being spiny at the apex (spiny in E. fuscula ).

Novantinoe noguerai can be included in the alternative of couplet 25 in the key from Santos- Silva and Hovore (2007) (translated):

25(21). Scape dorsally flattened on basal half. Bolivia........ N. germaini (Villiers, 1959)

- Scape not flattened on basal half...... 25′

25′(25). Elytral apex truncate; apex of meso- and metafemora with spine on both sides. Venezuela............. N. jolyi Santos-Silva and Hovore, 2007

- Elytral apex acute; apex of meso- and metafemora rounded on both sides. Mexico......... N. noguerai Santos-Silva and Le Tirant , new species
