Type Material: Holotype male from GUATEMALA, Izabal: Morales, Finca la Firmeza, Sierra de Caral, FUNDAECO, 600 m, 15.407148, -88.696255, 27-28.V.2019, Skillman, Wappes, and Monzón leg. (FSCA, formerly FWSC).

Etymology: The new species is dedicated to Frederick W. Skillman, Jr. (FWSC).

Remarks: Morrisia skillmani, sp. nov., differs from M. pulchra Santos-Silva et al., 2019, and M. squamosa (Chemsak and Noguera, 1993) by the lower eye lobes with 10 rows of ommatidia (fig. 3C). In M. pulchra the lower eye lobes have five rows of ommatidia (fig. 3B), and M. squamosa seven (fig. 3A). Furthermore, the elytra (fig. 3I) and pronotum are more coarsely punctate than in M. pulchra and M. squamosa (fig. 3G–H). This is the first record of the genus in Guatemala (fig. 2).

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. Leaven-good 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).
