Monné, Marcela L. & Monné, Miguel A., 2015, New species of Hemilophini (Coleoptera, Cerambycidae, Lamiinae) from Colombia and Ecuador, Zootaxa 4052 (2), pp. 229-232 : 231

Eulachnesia boteroi sp. nov. ( Fig. 2 )

Male. Head, antennae, thorax, legs, distal half of elytra and abdomen with black integument, basal half of elytra clear yellow. Head with dense vestiture of grayish pubescence, except posterior to upper eye lobes. Occiput and frons finely and very sparsely punctate; frons flat between eyes; upper lobe connected to lower lobe by 2–3 rows of facets at narrowest point; lower lobe as larger as upper lobe, as high as genae below. Antennae slender, extending beyond elytral extremity (antennomeres lacking from VIII). Scape linear, not dilated to apex; antennomeres III to VII with dense long hairs at ventral and internal margins.

Prothorax subcylindrical, slightly protuberant medially, narrower than elytral base. Pronotum with a median longitudinal stripe, covered with very sparse black pubescence, and a longitudinal stripe of blue pubescence each side; minute and sparse punctures restricted to black central stripe. A single row of punctures along posterior margin. Prosternal process narrow, approximately one fourth width of procoxae. Mesosternal process separating mesocoxae by about half width of mesocoxa.

Elytron without lateral carinae; with humerus moderately projecting posterolaterally. Apex emarginate, with a minute spine at sutural and marginal angles. Basal half yellow moderately densely punctate; black distal half covered with dense scale-like grayish pubescence, a blue longitudinal line of appressed pubescence closest to suture at anterior third of black area. Legs with femora and tibiae sublinear, with very sparse long hairs; metafemora extending to third urosternite. Apex of urotergite and urosternite rounded.

Etymology. The species is named as a tribute to our friend, Dr. Juan Pablo Botero, for his contribution to the study of Cerambycidae .

Measurements (mm), male. Total length, 14.7; prothorax length, 2.8; prothorax width, 3.0; elytral length, 10.5; humeral width, 4.0.

Type material. Holotype male. COLOMBIA, Nariño: Barbacoas, 60 m, 2.VIII.1984, M. Cooper col. ( BMNH).

Remarks. Monné (2015) list four species of Eulachnesia , E. smaragdina Bates, 1872 from Nicaragua, Costa Rica and Panama, E. humeralis (Fabricius, 1801) and E. monnei Martins & Galileo, 1996 from the Amazon region and E. cobaltina Bates, 1881 from Colombia. E. boteroi sp. nov. can be included in the alternative of couplet “2(1)” from Martins & Galileo (2014a) as follows:

2(1) Elytra with green or metallic blue stripes near the suture and margins, the dorsal surface black; elytral carina present. Brazil (Amazonas) French Guiana............................................................................................................... E. humeralis (Fabricius, 1801) - Elytra with the basal half yellow and the distal half black, with a narrow longitudinal blue line in the anterior third of the black area; elytra without carina. Colombia.................................................................................................................... E. boteroi sp. nov.
