Miguellus monnei sp. nov.

( Figs 14–17 )

Description. Male. Head mostly dark brown, with basal half of gena, part of area behind lower eye lobes, anteclypeus and part of labrum yellowish brown; antennae dark brown except pale yellow basal 4/5 of antennomere IV and basal 2/3 of antennomeres V–VI dark yellow brown; pronotum mostly dark reddish brown except dark brown semi-circular basal and distal fascia centrally (the basal one much wider than the apical); prosternum, central area of meso- and metaventrite dark brown; sides of meso- and metaventrite, most of mesanepisternum, mesepimeron and metanepisternum yellowish brown; elytra dark brown except light reddish tip of outer apical spine; coxae dark brown with minute reddish brown areas interspersed; peduncle of femora pale yellow, this area prolonged ventrally; remaining surface of femora dark brown; base of tibiae yellowish, with remaining surface dark brown; tarsi dark brown except yellowish claws; abdominal ventrites I–IV reddish brown laterally, with remaining surface dark brown; abdominal ventrite V mostly dark brown.

Head. Frons minutely, slightly distinctly punctate; with yellowish-white pubescence not obscuring integument. Area between antennal tubercles with yellow pubescence, denser, more conspicuous than in frons. Remaining surface of vertex nearly smooth; with yellowish-brown pubescence not obscuring integument, sparser near prothorax. Area behind upper eye lobes with yellowish-brown pubescence not obscuring integument, gradually yellower toward area behind lower eye lobes. Genae with yellowish-white pubescence not obscuring integument, especially near apex. Median groove distinct from clypeus to area between antennal tubercles. Antennal tubercles with pubescence as on frons, less conspicuous toward upper eye lobes. Distance between upper eye lobes 0.22 times length of scape; in frontal view, distance between lower eye lobes 0.36 times length of scape. Antennae 2.29 times elytral length, reaching elytral apex at about middle of antennomere VI; scape, pedicel and antennomeres III–IV with long, erect, sparse dark setae ventrally; antennal formula (ratio) based on length of antennomere III: scape = 1.28; pedicel = 0.13; IV = 0.87; V = 0.78; VI = 0.72; VII = 0.59; VIII = 0.65; IX = 0.63; X = 0.63; XI = 0.55.

Thorax. Prothorax 1.5 times wider than long. Pronotum with elongate, narrow gibbosity centrally, carinashaped, from apex of basal quarter to base of distal fifth; light area with ochraceous salmon pubescence obscuring integument; dark areas with slightly conspicuous brownish pubescence exposing integument; basal dark area coarsely, moderately sparsely punctate. Sides of prothorax with ochraceous salmon pubescence obscuring integument, except basal area with slightly conspicuous brownish pubescence exposing integument. Ventral surface of thorax with yellowish white pubescence not obscuring integument (more grayish white depending on angle of light source). Scutellum with brownish pubescence not obscuring integument. Elytra. Coarsely, abundantly punctate on basal 2/3, gradually sparser on distal third; with brownish pubescence not obscuring integument. Legs. Moderately short; apex of mesofemora nearly reaching apex of abdominal ventrite I; apex of metafemora reaching apex of abdominal ventrite IV.

Abdomen. Abdominal ventrites with yellowish white pubescence not obscuring integument.

Dimensions (in mm), holotype male. Total length, 5.80; prothoracic length, 0.85; basal prothoracic width, 1.10; distal prothoracic width, 0.85 (1.00 before constriction); greatest prothoracic width, 1.40; humeral width, 1.55; elytral length, 4.40.

Type material. Holotype male from ECUADOR, Napo: Cosanga (trail alongside bamboo), 6.XI.2015, J. McClarin col. ( QCAZ).

Etymology. Named for Miguel A. Monné (MNRJ) to recognize his lifetime of contributions to our knowledge of American Cerambycidae .

Remarks. The general appearance of Miguellus monnei is very similar to that of Pseudosparna pichincha Monné & Monné, 2014 (Acanthocinini) , also described from Ecuador, but differs as follows (males): scape proportionally shorter, uniformly and slightly widened from base to apex; elytral dorsal surface with single and well-marked carinae; elytral apex deeply notched; legs shorter (mesofemora reaching at about apex of abdominal ventrite I, and metafemora reaching apex of abdominal ventrite IV). In Pseudosparna pichincha , the scape is proportionally longer, more distinctly widened toward apex after middle, elytral dorsal surface with two moderately marked carinae, elytral apex sinuous but not deeply notched, and legs longer (mesofemora surpassing apex of abdominal ventrite I, and metafemora reaching apex of abdomen).
