Abdomen. Ventrites with dense pale yellowish-brown pubescence, except sparse pubescence on central region of ventrite 2, distinctly sparser yellowish-white pubescence on central area of ventrites 3–4 and base and apex of ventrite 5. Male. Unknown. Etymology. The epithet ‘ palliapicalis’ (from the Latin ‘ pallidus ’ (pale, discolored) and ‘ apex ’ (tip, end)) refers to dense yellowish-white pubescence on the apex of some antennomeres (the first four and the last). Type material. Female holotype from HONDURAS, Cortés: 4 km S Potrerillos, 1.VIII.1977, C.W. & L. O’Brien & Marshall leg. (FSCA, formerly RHTC). Female paratype from HONDURAS, Comayagua: 9 km WSW Siguatepeque, 2.XII.1995, R. Turnbow leg. (RHTC). Remarks. Phrynidius palliapicalis is similar to P. asper (see photographs on Bezark 2025) but differs as follows (females): antennal tubercles more distant, distance between apices slightly shorter than twice basal diameter of the antennomere III (Fig. 73); prothorax wider (Fig. 69); elytral tubercles small and more abundant (Fig. 69); and elytra slender (Fig. 69). In P. asper, the antennal tubercles are closer to each other, distance between their apices at most as wide as basal diameter of the antennomere III, prothorax is slender, elytra distinctly wider, and the elytral tubercles are larger and sparser. It differs from females of P. armatus Linsley, 1933 (see photographs on Bezark (2025), in Gutiérrez et al. (2020), and in Noguera & Santos-Silva (2023)) especially by the prothorax proportionally wider (slender in P. armatus), pronotal tubercles slightly conspicuous (distinct in P. armatus), and by the elytral tubercles small (distinctly larger in P. armatus). Phrynidius palliapicalis differs from P. hondureno (Figs 55–59) especially by the antennomere III distinctly shorter (longer P. hondureno), and by the pronotal tubercles slightly conspicuous and not concave anteriorly (distinctly more conspicuous and concave anteriorly in P. hondureno). It differs from P. zacapensis (Figs 60–68) by the eye lobes closer to each other (more distant between them in P. zacapensis), abdominal intercoxal process distinctly wider (narrower in P. zacapensis), and by the tibiae without squamiform white setae (present in P. zacapensis). Phrynidius palliapicalis differs from P. inaequalis (Fig. 80) especially by antennal tubercles more distant from each other (closer in P. inaequalis), and by the antennomere III longer (shorter in P. inaequalis). Finally, it differs from P. murallaensis (Figs 35–47) by the elytra proportionally wider (narrower in P. murallaensis) and by the metatarsomere V stouter and shorter (slender and longer in P. murallaensis).
