Differential diagnosis
Susuacanga marcelae sp. nov. is similar to S. poricollis (Chemsak & Linsley, 1973) in having the median lateral tubercle of pronotum projected in a long spine, apex of meso- and metafemora with spines shorter than the pedicel and elytra with posterior eburneous callosities shorter than the length of the scape. Susuacanga marcelae sp. nov. differs by the integument being yellowish-orange, the anterior eburneous elytral callosities contiguous as in the same way the posterior and the elytral apices bispinose. In S. poricollis the integument is dark brown, the anterior eburneous elytral callosities are separated between them as in the same way the posterior and the elytral apices have only an inner spine. The scape strongly depressed (Fig. 2E) is a unique characteristic among the species of Susuacanga.
Etymology
The specific name is a genitive patronym in honor of my friend and mentor Marcela L. Monné, for all her support during my graduate studies and in recognition of her work on Cerambycidae.
Material examined
Holotype
MEXICO: ♂ [no other data] (IRSNB).
Description
Male
Integument yellowish-orange. Ventrally darker. Apices of mandibles, antennal tubercles, basal half of scape, lateral spine of prothorax, and pronotal tubercles black.
Body covered by dense, yellowish pubescence. Antennal tubercles glabrous, apex rhomboid. Distance between upper lobes twice width of upper lobe. Coronal suture glabrous, interocular tubercle barely elevated, divided by suture. Antennae exceeding elytral apices at apex of antennomere VI. Surface of scape very rugose, narrowing toward apex, dorsally at base strongly depressed. Inner face of scape,
pedicel, and antennomeres III–VI with long erect setae, sparser to distal antennomeres.Antennal formula based on length of antennomere III: scape: 0.75, pedicel: 0.17, IV: 1.17, V: 1.27, VI: 1.35, VII: 1.40, VIII: 1.40, IX: 1.35, X: 1.35, XI: 2.92.
Prothorax transverse; antemedian lateral tubercle visible, glabrous and rounded at apex; median lateral tubercle projected in long and acute spine. Pronotum with dense grayish pubescence, with two anterior tubercles rounded at top; central gibbosity weakly elevated. Surface of pronotum with shallow wrinkles and punctures, obliterated by pubescence.
Elytra about four times longer than prothorax. Each elytron with four eburneous callosities: two basal, elliptical, contiguous, equal in size; and two posterior, elliptical, contiguous, the external slightly larger than inner; apices bispinose. Apex of meso- and metafemora bispinose, inner spine slightly longer than outer spine.
Measurements (in mm)
Total length: 38.5, prothorax length: 6.1, prothorax width at its widest point: 9.5, elytral length: 26, humeral width: 9.9.
Remarks
According to the most
recent key to species of the genus (Botero 2014), Susuacanga marcelae sp. nov. can be inserted into couple 9, as follows:
9. Median lateral tubercle of pronotum projected in long spine ……………………………………10
– Median lateral tubercle of pronotum rhomboid or slightly acute, but not spiniform ……………11
10. Integument dark-brown.Anterior eburneous elytral callosities separated between them as in the same way the posterior. Elytral apices with only an inner spine. Mexico (Michoacán, Puebla, Morelos, Guerrero, Oaxaca)………………………………………… S. poricollis (Chemsak & Linsley, 1973)
– Integument yellowish-orange. Anterior eburneous elytral callosities contiguous as in the same way the posterior. Elytral apices bispinose. Mexico ………………………………… S. marcelae sp. nov.
