Panabachia carltoni Muñoz-Tobar & Caterino, 2025, sp. nov.

Panabachia carltoni sp. nov. Figs 3 F, 4 L, 6 K Type material. Holotype • ♂ (MECN-EN 42138): “ Ecuador: Pichincha Pr. 50 km NW Quito, Reserva Maquipucuna, # 13, elv. 1350 m, 20 Dec. 1991, light, C. Carlton, R. Leschen ” / “ Caterino DNA voucher, Ext. MSC-13326, Morphosp. PanMaq 1 ”; deposited in MECN. Paratypes (1 ♂, 1 ♀) • same data as holotype (MECN-EN 42139 to 42140). Diagnosis. Body (Fig. 3 F) pale brownish-orange, with conspicuous whitish, subrecumbent setae; impunctate; head subquadrate, posterior corners rounded; vertexal foveae deeply impressed; eyes protuberant; antennal bases with very short stria behind; antennae short, basal two antennomeres similar in length, cylindrical, III subconical, IV – VIII short, subquadrate, IX wider, transverse, barely part of club, X – XI conspicuously larger, setose; pronotum broad, sides almost evenly rounded, slightly wider anterad; anterior part of male pronotal disk (Fig. 4 L) with transverse depression, bi-arcuate, anterior midpoint pointing posterad over middle, bearing few diverging setae at apex, depression glabrous within, setose particularly along posterior margins; laterad depression are very slightly raised, elongate oval disks, finely rugose but not setose within; posterior portion of pronotal disk with median fovea but otherwise unmodified; elytra with four approximately evenly spaced basal foveae; prosternum very short, hypomeron with anterior foveae; male metaventrite slightly swollen, otherwise unmodified; male last abdominal ventrite short, shallowly transversely depressed; margin of last male tergite unmodified. Aedeagus (Fig. 6 K) flattened, with basally separate parameres, and separate accessory sclerites; tegmen with apex expanded, membranous across front; accessory sclerites asymmetrical, one with short blunt tip, other with elongate, apically hooked tip. TL 1.32–1.35 mm, EW 0.33 mm. Distribution. This species is only known from the Maquipucuna Reserve, ca 35 km NW of Quito. Although several other species occur very close by (3 species at El Pahuma), none appear to be particularly closely related to this one. Etymology. We name this species to acknowledge the collaboration and assistance (in this and many other projects) of Dr. Christopher Carlton, who helped collect the types of this species. Remarks. There is limited material of this species, and the male dissection is not well sclerotized nor well cleared. Therefore several details are obscured. Nonetheless it does have several unique features, including the apical prolongation of one of the accessory sclerites. The dorsal velum (visible in Fig. 6 K) of the tegmen is possibly unique, but possibly also a remnant of an internalized tergite not extracted in other species.
