Pachyrhynchus analynae Obrial, Agbas, Pajota & Medina sp. nov.

Diagnosis: Pachyrhynchus analynae sp. nov. belongs to the P. speciosus species group. In general appearance, this novel species conspicuously resembles a cross between P. miltoni Cabras & Rukmane, 2016, from Marilog, Davao City, and P. cabrasae Rukmane, 2016, from Mt. Kalatungan, Bukidnon. It exhibits a combination of scaly maculations found in both congeners: the longitudinal scaly bands at pronotum which resembles P. miltoni, while reticulate scales at elytra resembles P. cabrasae. However, P. analynae sp. nov. differs with P. miltonibased on the following characteristics: amygdaloid elytral shape, narrower in profile, and tapers apically; elytra bears reticulate net-like maculations that merge and sparsely covered with setae from the apical declivity towards the apex (vs stouter elytra with minute setae only along the lateral margin; with open-and closed-banded variations, with three contiguous scaly bands, with open-banded variation that retains the three scaly bands in P. miltoni).

 Variability of Pachyrhynchus analynae Obrial, Agbas, Pajota & Medina sp. nov.:
A) open-banded, holotype male, B) filled-banded, paratype male
C) unfilled-banded, paratype, female, D) filled-banded, paratype female.
