Anabropsis rentzi Cadena-Castañeda and Cortés-Torres , new species

(Plate 1–2)

Diagnosis. Male and female macropterus. Pronotal disc with two spots arranged as follows: the first on the anterior margin of the pronotal disc, which is connected to a light stripe that stretches across the dorsal portion of the pronotal disc leading to another spot on the posterior margin that is larger than the spot on the anterior margin. Hind femur without dark rings in the distal region. In males, the cercus apex is shorter relative to the length of the cercs itself. The subgenital plate has the neck slightly concave.

Comparatives notes. Anabropsis rentzi n. sp. differs from the other two related species in many characters, especially in the ovipositor shape and general coloration. In the new species, the spots of the pronotal disc are connected across the dorsal region (Plate 5 C and D), whereas in A. alata , the pronotal disc is black with some brown spots (Plate 5A). In A. marmorata , the pronotal disc has the posterior margin black and many black strips on the rest of the pronotum (Plate 5B).

In A. marmorata , the central stripes on the face are inconspicuous (Plate 4B), while in the A. rentzi they are pronounced (Plate 4C). In A. marmorata the ovipositor is curved sharply in the middle and the apex is acute (Plate 6A), while in A. rentzi n.sp. the ovipositor is curved gradually from the middle and the apex is blunt (Plate 6B) (in the type of A. alata the abdomen is absent).

Paratype. Ƥ Colombia, Risaralda, Mistrato, quebrada el Empalato. 1800 m.s.n.m. 31 March 1992. Col. G. Andrade leg. (01426). Depository: Museo de Historia Natural del Instituto de Ciencias Naturales, Universidad Nacional de Colombia (ICN). Bogotá.

Description. Head: Rounded to the fronto-clipeal suture, thereafter, the mandibular portion lengthens. Fastigium does not exceed the medial length of scapus and as thin as the pedicel; eyes elongate at the same level of base antennae. eyes Frons smooth with prominent central ocellus, face ornamented with some bands, with the main band under the eyes, on the fronto-clypeal suture; another band connected to another upper band that surrounds the upper margin of the eyes, the same position as the lower margin of the scape and fastigium. Clypeus long as the labrum, the latter with a medial stripe. Jaws developed without exceeding the length of the labrum. Thorax: Pronotum short and smooth, latero-posterior margins slightly expanding. Pronotal disc with a spot on the anterior margin, which is connected to a light stripe that stretches across the dorsal of pronotal disc to another spot on the posterior margin which is larger relative to spot on the anterior margin. Prosternum with spines, mesosternum with anterior margin straight and posterior margin of two long sharp processes, meso-furcal furrow constricted and round. Metasternum with anterior margin shorter than the posterior, expanding laterally and coalesceing into two moderate extensions (smaller than the mesosternal processes). Wings: Macropterus. Tegmina far surpassing the length of the abdomen, Cu vein branching toward the middle of the length of the tegmina and Rs vein branching near the distal third of the course of the vein M. Fore legs: External face of the base of the coxa armed with a sharp spine and apex of the inner face with a blunt spine, femur with the lower-external margin armed with two small spinules, genicular lobes unarmed. Tibia with the tympanum exposed on both sides, dorso-external margin with a spine and ventral margin with four spines in both sides. Dorso-external and dorso-internal margin with a spine antero-apical each, apex with two spines; tarsi elongated and unarmed dorsally. Middle legs. Coxa with a slight prolongation apically, femur unarmed on both margins, genicular lobes armed. Tibia with three spines on dorsoexternal margin, four on the dorso-internal margin, apex with two spines. Hind legs. Uniform femur and armed ventrally with three spines on each margin, ventral side without teeth for acoustic production. Abdomen: Tenth tergite straight, with two cerciform appendices emerging under epiproct. Subgenital plate elongate but not exceeding 0.5 times the length of the appendices cerci; styles cylindrical.

Female: Similar that male in shape and size. Ovipositor with the apex lanceolate, upper valve wide and exceeding the lower valve. Subgenital plate triangular, tapering towards acute apex.

Variation. The female has the facial stripes less pronounced than in other specimens (holotype and paratype) (Plate 4 C, D and E), likewise, the paratype has the pronotal disc spots faint but distinguishable (Plate 5 C and D).

Etymology. This species is named in honor of Dr. David Rentz.
