DESCRIPTION: Holotype male. Integument mostly dark brown, almost black; apex of palpomeres reddish brown.

HEAD: Frons coarsely, abundantly punctate; with moderately thick, short, decumbent, yellow and white setae obscuring integument. Area between antennal tubercles and upper eye lobes coarsely, abundantly punctate; with a few short, yellow and white setae centrally; sides with abundant, moderately thick, short, decumbent, yellow and white setae partially obscuring integument. Remaining surface of vertex coarsely, abundantly punctate; with yellow pubescence not obscuring integument, and white setae interspersed (some punctures with short brownish seta). Area behind eyes and genae coarsely, abundantly punctate; with abundant, decumbent, moderately thick yellow setae and white setae with same shape interspersed (white setae more abundant on genae); area close to upper eye lobes with a few long, erect brownish setae. Postclypeus with setae as on frons, and moderately long, white setae interspersed. Labrum coplanar with clypeus at posterior 2/3, inclined at anterior third; posterior third with abundant yellowish pubescence, and long, abundant whitish setae directed forward interspersed; anterior third with dense yellow pubescence. Basal 2/3 of outer side of mandibles with abundant, short,

decumbent, yellow and white setae not obscuring integument; apical third glabrous. Eyes almost divided; lower eye lobes with nine rows of ommatidia; distance between upper eye lobes 0.45× distance between outer margins of eyes; in frontal view, distance between lower eye lobes 0.68× distance between outer margins of eyes. Antennae missing antennomeres III–XI in left antenna; missing pedicel and antennomeres III–XI in right antenna; scape slightly widened basally, then subcylindrical toward apex, shorter than width between upper eye lobes, about 2.5× longer than pedicel, with short, thick, decumbent, abundant, yellow and white setae partially obscuring integument; pedicel with abundant, decumbent, yellow and white setae partially obscuring integument.

THORAX: Prothorax longer than wide; sides uniformly rounded from anterolateral angles to posterior quarter, then subparallel toward posterolateral angles. Pronotum coarsely, reticulate-punctate, punctures slightly finer on anterior quarter; sides with short, decumbent, thick, abundant, yellow and white setae (denser and more abundant on anterior third); area after middle, between sides and center with moderately sparse, thick, decumbent yellow setae and a few similar white setae interspersed; center with fragmented, longitudinal band with yellow, thick, decumbent setae; punctures with bristly, fine brownish seta; area between punctures on anterior half with short, decumbent brownish setae not obscuring integument, more abundant on anterior third. Sides of prothorax with sculpturing as on pronotum; with abundant, decumbent, thick, both yellow and white setae not obscuring integument; with a few long, erect brownish setae on posterior third. Prosternum coarsely, abundantly punctate; sides with abundant, thick, decumbent yellow setae, and a few similar white setae interspersed; central area with sparse yellow setae. Prosternal process with abundant, decumbent, yellow and white setae not obscuring integument; narrowest area 0.31× procoxal width. Ventral surface of mesothorax coarsely, abundantly punctate; sides with abundant, thick, decumbent, yellow and white setae; mesoventrite mostly with fine, decumbent, whitish pubescence not obscuring integument, and yellow setae interspersed; mesoventral process with abundant, fine whitish pubescence not obscuring integument, moderately narrowed centrally, and apical width 0.45× mesocoxal width. Ventral surface of metathorax coarsely, abundantly punctate laterally, punctures slightly finer on center of metaventrite; sides with abundant, decumbent, thick yellow and white setae interspersed; central area of metaventrite with abundant, fine, decumbent white setae not obscuring integument. Scutellum with dense, thick decumbent, yellow setae interspersed with a few white setae. Elytra. Slightly, gradually widened from humerus to posterior quarter, then roundly narrowed toward apex; in side view, distinctly arched from basal sixth; coarsely, deeply punctate, punctures coarser on wide central area; basal fifth with decumbent, thick, yellow and white setae not obscuring integument; with wide, oblique white pubescent band from anterior third to about middle, not reaching epipleural and sutural margins, and moderately abundant similar yellow setae interspersed; posterior quarter with abundant, decumbent, thick white and yellow setae interspersed; sutural region with decumbent, thick yellow and white setae interspersed; dorsal area between anterior fifth, oblique white pubescent band and sutural region, and area between middle and posterior quarter with brownish pubescence distinctly not obscuring integument. Legs. Femora, tibiae, and tarsi with abundant, decumbent, yellow and white setae partially obscuring integument, except ventral surface of protibiae with bristly, abundant brown pubescence, and ventral surface of meso- and metatibiae with bristly, thick yellowish-brown setae, denser apically.

ABDOMEN: Ventrites moderately coarsely and abundantly punctate, punctures gradually finer toward ventrite 5, except almost smooth apex of ventrites 1–4; sides of ventrites 1–5 and apex of 1–4 with abundant, short, decumbent yellow setae and short, decumbent white setae interspersed; remaining surface of ventrites with abundant pubescence composed of white setae but not obscuring integument.

DIMENSIONS (mm): Total length, 5.90; prothoracic length, 1.80; anterior prothoracic width, 1.35; posterior prothoracic width, 1.40; maximum prothoracic width, 1.65; humeral width, 1.70; elytral length, 3.50.

TYPE MATERIAL: Holotype male from MEXICO, Chiapas: Tuxtla Gutiérrez – Sumidero , flowering tree, 9.VI.1991, F.W. Skillman leg. ( FSCA, formerly FWSC). Paratype from MEXICO, Chiapas: Tepehuaje, El Mirador Sumidero Canyon , beating, 5.VII.2021, J. Rifkind, J. Leavengood and E. A. Martinez col. ( LGBC) .

ETYMOLOGY: The species is named after the word used in Zoque language to refer to insects, jejetam ( Sánchez Álvarez, 1963). The Zoque are an indigenous people of Mexico who live near the area where the species was collected.

REMARKS: Adetaptera jejetama , sp. nov., resembles species of Morrisia Santos-Silva et al., 2019 . However, the membranous wings are absent, as in the species of Adetaptera et al., 2019, while they are present and well formed in Morrisia . Adetaptera jejetama differs from the other species currently known in the genus by the elytra distinctly wider basally than the base of the prothorax, and elytra very coarsely punctate (about as wide, and finer in all other species).
