Sparna tavakiliani   sp. nov.

( Figs 1–4 View FIGURES1–8.1–4 )

Description. Male. Integument mostly dark brown, almost black, especially dorsally; anteclypeus, distal half of labrum, part of mandibles reddish brown; basal 3/4 of antennomeres IV –VI dark reddish brown; area close to lower eye lobe and gena with irregular, yellow spot; apex of lateral spines of prothorax reddish brown; each elytron with large, transverse yellow macula after middle, reaching lateral margin but not suture.

Head. Frons microsculptured; with yellowish pubescence not obscuring integument (more grayish white depending on angle of light source). Vertex finely, sparsely punctate; with brownish pubescence partially obscuring integument, except glabrous central area close to prothoracic margin. Area behind eyes with brownish pubescence partially obscuring integument, except yellowish pubescence on area with lighter integument. Genae finely, transversely striate on central area; with sparse yellowish pubescence. Median groove distinct from clypeus to prothoracic margin, slightly carina-shaped on frons. Antennal tubercles with brownish pubescence partially obscuring integument. Distance between upper eye lobes 0.12 times length of scape; in frontal view, distance between lower eye lobes 0.24 times length of scape. Antennae 1.65 times elytral length, reaching elytral apex at basal quarter of antennomere VIII; antennal formula (ratio) based on length of antennomere III: scape = 1.22; pedicel = 0.08; IV = 0.35; V = 0.46; VI = 0.38; VII = 0.46; VIII = 0.43; IX = 0.43; X = 0.34; XI = 0.30.

Thorax. Prothorax 1.6 times wider than long (including lateral spines). Pronotum with 3 gibbosities, one elongate, somewhat carina shaped, from near base to near apex, distinctly more elevated on basal half, one subelliptical and larger on each side of central area; moderately finely and sparsely punctate on basal quarter; remaining surface densely micropunctate; with dark brown pubescence partially obscuring integument laterally, sparser on transverse basal and distal area, nearly absent on remaining surface. Prothorax with sides finely and sparsely punctate; with brown pubescence partially obscuring integument. Ventral surface of thorax with yellowish pubescence not obscuring integument (more yellowish-brown on metaventrite). Scutellum with brownish pubescence not obscuring integument. Elytra. Coarsely, abundantly punctate on basal half, gradually sparser toward apex; almost entirely rugose; slightly dentate laterally, near apex; dorsal carinae not fused distally; with pubescence not obscuring integument, pubescence yellowish brown except lighter on yellow spot. Legs. Moderately short; apex of mesofemora slightly surpassing middle of abdominal segment I; apex of metafemora slightly surpassing middle of abdominal segment IV.

Abdomen. Abdominal ventrites with yellowish pubescence not obscuring integument.

Dimensions (in mm), holotype male. Total length, 10.12; prothoracic length, 1.12; basal prothoracic width, 1.53; distal prothoracic width, 1.23 (1.44 before constriction); greatest prothoracic width, 1.89; humeral width, 2.11; elytral length, 7.87.

Type material. Holotype male from COLOMBIA [remaining information unreadable], no date indicated, G. Reineck col. ( MZSP).  

Etymology. Named for Gérard L. Tavakilian ( MNHN), to recognize his many contributions on the study of Cerambycidae   , and for his valued friendship.

Remarks. Sparna tavakiliani   sp. nov. differs from S. lycoides   (see photograph at Bezark 2017) as follows: elytra with large, transverse yellow spot on distal half; elytra slightly dentate near apex laterally; dorsal elytral carinae not fused distally. In S. lycoides   the elytra lack a yellow band, are not dentate laterally, and the dorsal carinae are fused distally.
