Five new species of Euplocania from Colombia belonging in four species groups are here described and illustrated. They increase to 22 the number of species described in the genus, thirteen of which are endemic to Colombia, with one species shared with Brazil and Peru. Three new species groups of Euplocania are here diagnosed. A key to the identification of males of Colombian Euplocania is included.

Specimens collected in the framework of the project “Revisión Taxonómica y Endemismo de los Psócidos (Insecta: Psocodea: ‘Psocoptera’) de Areas Protegidas de Colombia”, financed by Colciencias-Universidad del Valle, increase this number to 31 species, 22 of them undescribed.
Ten males and four females were available for study. They belong to the collection of the Group of Entomological Investigations (Departamento de Biología, Facultad de Ciencias Naturales y Exactas, Universidad del Valle, Santiago de Cali, Colombia), and are deposited in the Entomological Museum of the Universidad del Valle (
One male and one female of each species were dissected in 80% ethanol, and their parts (head, right wings and legs and terminalia), were mounted on slides in Canada balsam, following standard procedures. Color was recorded by placing whole specimens, before dissection, under a stereoscopic microscope, illuminated with cold, white light at 50×. Parts on the slides were measured, following standard procedures, and the measurements are given in mm; the illustrations were made from digital photographs, taken with a Canon T5i camera and Helicon Focus program, processed in a vector graphics editor Clip Studio Paint.
Abbreviations of parts measured are as follows:
al/ah areola postica length/height
ctt1 number of ctenidiobothria on t1
f1-fn lengths of flagellomeres 1-n of right antenna
F, T, t1-t3 lengths of femur, tibia, and tarsomeres 1-3 of right hindleg
FW and HW lengths of fore- and hind wings
IO, D, and d minimum distance between compound eyes, antero-posterior diameter and transverse diameter, respectively, of right compound eye, all in dorsal view of head
L/W forewing length/forewing width
lp/wp pterostigma length/pterostigma width
l/w hindwing length/hindwing width
Mx4 length of fourth segment of right maxillary palpus
MxW maximum width of head capsule in frontal view
PO d/D, H: head length (in dorsal view)

The species of Euplocania here dealt with, have increased the spectrum of morphological variability within the genus, making necessary the creation of three additional species groups, modifying the initial scheme presented by
Group Guentherbuchi. Forewings hyaline. Pterostigma elongate, not angulated towards Rs (Fig.
Group Laelsa. Forewings with a broad, pigmented marginal band from R4+5 to Cu2-1A. Pterostigma elongate, not angulated towards Rs (Fig.
Group Yalcona. Forewings with a slender, pigmented marginal band, from R4+5 to areola postica (Fig.
The species here treated raise to 22 the species known in the genus, and raise to 14 the species of the genus known in Colombia (Table
