Diagnosis

Sparna sarae sp. nov. differs from congeneric species by the pronotum tricolorous and with different pubescent pattern, orange laterally, except yellowish-white pubescence on the area of the prothoracic tubercles, and with dark-brown pubescence centrally, except glabrous longitudinal center. Sparna sarae also differs from S. tavakiliani Santos-Silva, Galileo & McClarin, 2018 by the orange pubescence on the posterior area of the elytra and by the apex of the elytra without small projection laterally. In S. tavakiliani , each elytron has a transverse yellow macula on the posterior half and the apex of the elytra has a small projection laterally.

Etymology

This species is dedicated to the mother of the third author, Sara Sarmiento de García, thanking her for her unconditional support and affection.

Description

Female holotype ( Figs 22–25 )

COLORATION. Integument mostly dark brown. Antennomere III brownish basally; IV yellow except brown apex; antennomeres V–XI brown, V–VII darkened apically. Anteclypeus and anterior margin of labrum dull yellowish brown. Pronotum dark brown centrally, light brown on remaining surface, except yellow lateral area close to posterior margin. Elytra orangish just after middle. Profemoral peduncle yellow; meso- and metafemoral peduncle partially yellow. Ventral abdominal region brown.

HEAD. Frons microsculptured, with a few coarse punctures interspersed; with abundant yellowish-white pubescence not obscuring integument, on inferior half and sides, pubescence more grayish-white depending on light source, and moderately sparse brown pubescence on superior half, except yellowish-white pubescence close to median groove. Vertex sparsely punctate, with sparse yellowish-white pubescence between antennal tubercles and moderately abundant brownish pubescence not obscuring integument on remaining surface. Genae finely, transversely striate on central area, with moderately sparse whitish pubescence except glabrous apex and central area close to eye. Antennal tubercles with brown 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 as long as scape. Antennae 1.65 times elytral length. Scape, pedicel, and antennomere III with brown pubescence partially obscuring integument; scape with moderately abundant, erect dark-brown setae ventrally; pedicel with a few erect dark setae ventrally; III with dense, long, erect dark-brown setae ventrally, and abundant, short, erect dark-brown setae dorsally. Antennal formula (ratio) based on length of antennomere III: scape = 1.19; pedicel = 0.09; IV = 0.62; V = 0.50; VI = 0.45; VII = 0.42; VIII = 0.39; IX = 0.39; X = 0.34; XI= 0.29.

THORAX. Prothorax wider than long; sides divergent from anterolateral angles to lateral tubercles, then convergent toward posterolateral angles; lateral tubercles conical, located near posterior fifth. Pronotum with two slightly distinct gibbosities on anterolateral region; finely punctate, with transverse row of coarse punctures near posterior margin, and sparse coarse punctures interspersed on remaining surface, except smooth central region; sides with abundant yellow pubescence not obscuring integument on anterior ⅔ close to dark integumental area, orangish on remaining lateral areas, except yellowish-white pubescence on lateral tubercles of prothorax; central area with abundant dark brown pubescence from near anterior margin to posterior margin, except glabrous longitudinal central region. Scutellum with abundant dark-brown pubescence.

ELYTRA. Abundantly, coarsely, punctate, punctures slightly denser and finer on anterior dark integumental area, slightly sparser and coarser on light integumental area, except close to apex, where they are absent. Dorsal carinae fused posteriorly, continuing as a single carina that does not reach elytral apex. Surface with brown pubescence on dark integument area and orange pubescence on light integumental area; apex uniformly, individually rounded.

LEGS. Apex of mesofemora not reaching middle of ventrite 1; apex of metafemora slightly surpassing middle of ventrite 4.

ABDOMEN. Ventrites with whitish pubescence not obscuring integument; apical margin of ventrite 5 concave.
