Lycoderides abditus Sakakibara, 2013 View in CoL

Remarks: Lycoderides abditus was described based on a male specimen from French Guiana ( Fig. 7 View FIGURE 7 ), collected using an interception trap (vitre) at Mont Itoupé (570 masl) ( Sakakibara, 2013). Recent sampling and research in French Guiana by JL led to the collection of additional male specimens of L. abditus , as well as other specimens that were presumed to be females based on morphological similarities with males (i.e., scutellum covered by pronotum, dorsal contour, and forewing coloration), and their resemblance to females of L. serraticornis and L. santainensis sp. nov. (i.e., anterior process shape). Subsequent DNA barcoding analyses confirmed that these females belong to L. abditus (see Fig. 1 View FIGURE 1 & Table 1 in Lapèze & Lopez-Vaamonde 2024). Five of these presumed L. abditus females were barcoded using the “single-molecule real-time sequencing” method. All sequences obtained matched the Barcode Index Number of the male L. abditus : BOLD:AEC2962 (see Fig. 1 View FIGURE 1 & Table 1 in Lapèze & Lopez-Vaamonde 2024). DNA sequence data and images are available in BOLD (dx.doi.org/10.5883/DS-LYCODER).

The females of L. abditus closely resemble those of L. santainensis sp. nov. and L. serraticornis , just as the males of L. abditus are similar to those of L. aburraensis sp. nov., L. santainensis sp. nov., and L. serraticornis . Known localities are situated between 0 and 350 masl; most specimens were captured using light traps (mercury lamps), but no in situ behavioral observations could be made, and the natural history of this species remains unknown. Additionally, Sakakibara (2013) indicated the holotype repository is MNHN (Muséum National d’Histoire Naturelle, Paris, France), but it is currently housed in DZUP, Curitiba, Brazil.

Diagnosis: Male ( Fig. 2A View FIGURE 2 , 4A View FIGURE 4 , 5A View FIGURE 5 , 7 View FIGURE 7 ). Pronotum elevated above the head, 1.5x head length in frontal view, descending behind the humeral angles; suprahumeral horns small, wart-like; without anteroventral carina below the suprahumeral horns; metopidium slightly reclined anteriorly; pronotum with a wax-like line adjacent to the supraocular callosity. Forewing sparsely speckled at the apical third, with veins lacking warts. Female. Variegated light brown to dark brown. Waxy pubescence present on the pronotum, extending from the anterior margin, crossing posterior to the supraocular callosities, and reaching the posterior area of the metopidium. Pronotum elevated above the head, 2x head length in frontal view; pronotal anterior process 0.5x pronotum height, with a sinuous posterior margin. In lateral view, the subapical crest of the posterior process is well elevated. Forewing veins lacking warts.

Description: Female ( Fig. 2B View FIGURE 2 , 4B View FIGURE 4 , 5B View FIGURE 5 ): Color: Variegated light brown to dark brown. Post-clypeus and contiguous area on vertex and supra-antennal ledges dark-brown, posterior half of vertex light brown. Eyes and ocelli brownish gray. Pronotum dark brown, with warts, suprahumeral horns carinae and dorso-medial carina yellow; supraocullar callosities brown; humeral angles and adjacent area over basal ¼ of forewing clavus, as well as the subapical depression and tip of the posterior pronotal process, light brown to brown. Forewing sclerotized and punctuated up to half its length; basal ¼ brown, followed by a transversal dark brown band extending through the basal 1/3, with a yellow triangular area posteriorly; apical half of the forewing membrane is opaque hyaline, sparsely speckled with brown; veins brown. Legs light brown; femora and tarsomeres brown; coxae brown.

Sculpture: densely and coarsely punctuated, giving an overall opaque appearance. Light brown pubescence, sparsely distributed on the pronotum, sclerotized areas of the forewing, dorsal surface of the tibiae, and tarsomeres. Waxy pubescence present on pronotum, extending from anterior margin, crossing posterior to the supraocular callosities, and reaching the posterior area of the metopidium, as well as along the mesothorax margin, femora, and tibiae. Wart-like protuberances scattered across the anterior pronotal process, metopidium, and the area surrounding the humeral angles.

Thorax: Pronotum in frontal view ( Fig. 2B View FIGURE 2 ) more or less triangular, with an anterior process elevated 1x head length above the metopidium; suprahumeral horns triangular and carinate, each carina surrounded by warts; dorso-median carina extending distinctly from the anterior margin of the metopidium to the posterior process; in lateral view ( Fig. 3B View FIGURE 3 ), pronotal horn directed obliquely antero-dorsally, with sinuous dorsal margin descending to the posterior third, then forming a small crest before reaching the posterior margin of the posterior process, which extends above the claval apex; in dorsal view ( Fig. 4B View FIGURE 4 ), suprahumeral horns small and triangular. Scutellum completely covered. Tibiae with flattened dorsal surface.

Measurements: male/female (mm): Body length: 5.8/6.85; pronotum length: 4.55/5.13; pronotum height: 1.83/2.74; forewing length: 4.91/5.89; width between humeral angles: 2.05/2.23; head width: 1.81/1.99; vertex length: 0.64/0.74; vertex width: 1.21/1.37.
