Two new species of Edmockfordia García Aldrete (Psocodea, ‘Psocoptera’, Epipsocidae), from Valle del Cauca, Colombia, and description of the female E. chiquibulensis García Aldrete

Abstract Two new species of Edmockfordia García Aldrete, from Valle del Cauca, Colombia, and the female of Edmockfordia chiquibulensis García Aldrete, are described and illustrated. A key to the species of Edmockfordia is included; the genus was previously known only from Belize. The genus is re-diagnosed to include female characters. The distribution of the genus is considerably widened, from Belize to northeastern South America.


Introduction
The genus Edmockfordia was described by García Aldrete (2009) on the basis of three male specimens collected with Malaise traps at the Chiquibul Forest Reserve, Belize; numerous additional specimens from the same locality have become available since, including females of E. chiquibulensis. Two male specimens, representing each a different, undescribed species, were recently collected in Valle del Cauca, Colombia; the purpose of this work is to describe those two species and to re-diagnose the genus, to include female characters, besides, the distribution of the genus is extended from Belize to northern South America.

Material and methods
The Colombian specimens available for study were collected with led light traps, at the Pericos Natural Reserve and El Danubio, in Buenaventura, Valle del Cauca, Colombia. The Belizean specimens were collected in flight interception traps, at the Chiquibul Forest Reserve, Cayo District, Belize. The specimens for microscopic examination were dissected in ethanol 80%, and their parts (head, right wings and legs, and genitals) were mounted on slides in Canada balsam, following the procedure in González et al. (2011). The whole specimens, before dissection, were placed in 80% ethanol and observed with a Nikon SMZ 645 microscope, for color description. Standard measurements were taken on the slides, utilizing a Nikon E200 microscope; the measurements are given in µm, and the abbreviations of parts measured are the following: FW, HW: lengths of right fore-and hind-wings, F, T, t1, t2: lengths of femur, tibia, and tarsomeres 1 and 2 of right hind leg, ctt1: number of ctenidobothria on t1 of right hind leg, f1…fn: lengths of flagellomeres 1...n of right antenna, IO, D, d: minimum distance between compound eyes, antero-posterior diameter and transverse diameter, respectively, of right compound eye, all in dorsal view of head Etymology. It is our pleasure to dedicate this species to Nadia Calderón, a graduate student at the Universidad del Valle, who, together with Oscar Saenz Manchola, collected the specimens of the two species of Edmockfordia here described.

Diagnosis.
Phallosome with three posterior projections, with posterior end broadly W shaped; external parameres short, little developed; aedeagal arch slightly projected posteriorly; epiproct broadly rounded posteriorly. Color (in 80% ethanol). Body mostly pale brown, with creamy areas, as indicated below, pronotum, propleura and metapleura brown, upper half of mesopleura brown, lower half creamy; meso-and metanotal lobes creamy, bordered with brown. Abdomen creamy, clunium brown. Head (Fig. 2), with a brown transverse band between compound eyes enclosing the ocellar triangle; vertex creamy; genae brown; ocelli hyaline, with dark brown centripetal crescents; postclypeus brown, anteclypeus centrally brown, sides creamy; labrum pale brown anteriorly, fading towards the posterior margin. Antennae with scape and pedicel brown, flagella pale brown. Maxillary palpomeres 1-4 brown. Legs: front coxa, and trochanters of all legs creamy; coxae of mid and hind leg with a dark brown spot on outer border; femora mostly creamy, with a brown spot on proximal and distal ends; tibiae and tarsi pale brown. Forewings hyaline, pterostigma with a brown spot distally, and a brown band proximally; veins brown, each with a brown spot distally, at wing margin; a brown spot at nodulus. Hindwings hyaline, veins pale brown, with brown spots distally, at wing margin. Epiproct and paraprocts creamy. Hypandrium creamy, with postero-lateral corners brown.

Etymology.
We take pleasure to dedicate this species to Oscar Saenz Manchola, one of its collectors, a graduate student at the Universidad del Valle, Santiago de Cali, Colombia.
Diagnosis. Differing from E. calderonae and from E. chiquibulensis in having the phallosome aedeagal arch apically rhomboid, in having the external parameres extremely long, falcate, reaching the level of the aedeagal apex, and in having the postero-lateral corners of the epiproct rounded, protuberant.
Color (in 80% ethanol). Body mostly brown, with creamy areas, as indicated below, pronotum and propleura brown; meso-and metanotal lobes creamy, bordered with brown, upper halves of meso-and metapleura brown, lower halves creamy. Abdomen creamy. Head (Fig. 7), with a broad, transverse, dark brown band between compound eyes, enclosing the ocellar group; vertex creamy; genae proximally creamy, distally brown; ocelli hyaline, with ochre centripetal crescents; postclypeus brown, anteclypeus brown in the center, creamy on the sides; labrum creamy. Antennae with scape and pedicel brown, flagella pale brown. Maxillary palpomeres 1-4 brown. Legs: coxae and trochanters creamy; femora mostly creamy, with a brown spot on proximal and distal ends; tibiae and tarsi pale brown. Forewings hyaline, pterostigma with a brown spot at the apex, and a brown band proximally, veins pale brown, each with a brown spot distally, at wing margin, a brown spot at confluence of Cu 2 and A. Hindwings hyaline, veins pale brown, each with a brown spot distally, at wing margin. Clunium brown, epiproct pale brown, with sides dark brown; paraprocts pale brown, hypandrium almost unpigmented.
Remarks. Of the two paratypes for this species, one of them presents a forewing vein pattern with a four branched M, as described for the genus, however, a second specimen present the distal third of the forewing reticulated (Fig. 11) (e. g. R4+5 and M1 connected by a cross vein, R4+5 distally forked, a vein arising from the middle of R4+5 forked at wing margin, with the second branch fused at wing margin with M1, forming a closed cell, M1 absent, and M3 branched, with the branch near the areola postica incomplete.

Discussion
The species here dealt with extend the distribution of Edmockfordia from the Chiquibul Forest Reserve, in Belize, to Valle del Cauca, Colombia, all across Central America to northern South America. The two new species confirm the diagnosis of the genus: vein M in forewing dichotomously branched, side struts of phallosome stout, curved anteriorly, external parameres conspicuous, aedeagal arch projected posteriorly, paraprocts with a sclerotized band along inner border, and epiproct trapeziform, bearing a field of papillae mesally, next to the posterior border. The three species known in the genus differ in genitalic details, as indicated in the key above.
