(figs. 46–58)
Diagnosis. Antennae with 22 or 23 segments. Tegmina extending to sixth abdominal segment. Male cerci bifurcated, laterally flattened; superior branch frontally undulated, inferior branch smaller than superior, base expanded, apex curving smoothly downwards. Ovipositor with slender valves, inferior valves shorter than superior.
Holotype. ♂. Guatemala, Huehuetenango, Barillas, Unión Las Palmas. 1444 m. Latitude: 15.9311000, longitude: -91.2993100. 18–28 July 2011. Camposeco and Monzón leg. (MUD).
Allotype. ♀. Same data as holotype.
Description. Male. Antenna with 22 segments. Vertex fastigium projecting in the middle of antennae without extending past scape. Eyes circular and prominent. Pronotum cylindrical and rectangular, delimited with four sulci, postero-inferior margin of lateral lobule more developed than anterior margin, metazona with numerous pores. Legs: anterior femora softly thickened and ventrally unarmed, anterior and mesotibiae armed with small spinules on ventral margin, posterior femora with regular shape and ventrally unarmed, posterior tibiae with twelve pairs of spines on dorsal margin. Tegmina ovoid, extending up to the base of the sixth abdominal terguite, venation reticulated. Abdomen fusiform, curving smoothly from mesal portion to apex, tympanum exposed on first abdominal segment. Tenth terguite constricted, epiproctum conical, lateral margin marked and smoothly undulate. Cerci on lateral view robust, bifurcated, with upper branch longer than inferior, conical and frontally undulated, basal branch reduced and curving smoothly towards base. Subgenital plate dome shaped and slightly divided in the medial margin. Phallic complex: ectophallic valvae slender, projecting together towards the front, ectophallic projections originating at the base of the valvae, thinning from the base to apex, projections hook shaped in lateral view, apex undulated and sharp. Endophallus belt shaped in lateral view, slightly thickened and constricted distally. Epiphallus with basal disc “U” shaped and projecting backwards, lophi reduced and with interior border serrated.
Female. Similar in shape to male, slightly larger. Antennae with 23 segments. Tenth terguite constricted. Epiproctum triangular, longer than wide. Cerci conical, svelte and with apex sharp. Ovipositor valvae slender, inferior ones longer than superior. Subgenital plate with apex elongated and sharp.
Etymology. It is a pleasure to name this species for Faustino Rene Camposeco who is a great field collector, friend, companion and has assisted in the collecting of specimens for this work.
Measurements (mm) ♂/ ♀. Tl: 16/19, P: 2.5/3, Hf: 12/15, Ht: 12/16, Sp: 2/3.5, Ov: 3.
