Vinasco-Mondragón, Andrés Felipe, González-Obando, Ranulfo & García Aldrete, Alfonso N., 2022, New species of Euplocania Enderlein (Psocodea: ‘ Psocoptera’: Psocomorpha) from Colombia and Ecuador, Zootaxa 5188 (2), pp. 101-120 : 114-117

Euplocania ticuna n. sp. Male

( Figs 37–42 )

Diagnosis. This species does not belong in any of the Euplocania species groups. It differs from other species of Euplocania that also present the hypandrium with a single sclerite ( Fig. 42 ), by pattern of the forewings, shape of the phallosome sclerites and details of the shape of the hypandrium. Forewings of five branches, with M 4 and M 5 forked; cells cu1 and cu2 with brown areas; pterostigma with proximal and distal dark brown bands; hypandrium with pair of posterior projections strongly widened, each with two short posterior processes, one external and one internal, internal one with macrosetae basally. Phallosome with side struts slender, V-shaped, anterior pair of endophallic sclerites very close together at its posterior end, giving the appearance of a V; lateral sclerites broad, curved, angled out. Pair of mesal sclerites almost close to the midline, each with a short posterior process. Therefore, a new species group is proposed for this species, the ticuna group (see discussion below).

Color (of parts mounted on slide). Head ( Fig. 39 ) dark brown; compound eyes black; ocelli hyaline, with ochre centripetal crescents. Clypeus, labrum and genae dark brown. Genae with transverse narrow stripes. Maxillary palps dark brown, Mx1 paler. Legs: Coxae brown, fore- and mid- femora pale brown, with two brown spots; hind- femora dark brown, light brown apically; trochanters light brown, tibiae and tarsi pale brown. Forewings ( Fig. 37 ) mostly hyaline, brown spots at veins ends and on apex of areola postica, other spots as in diagnosis. Hindwings ( Fig. 38 ) hyaline, veins brown. Hypandrium brown. Epiproct and paraprocts light brown; paraprocts with dark hemispherical area on outer edge of trichobothrial fields. Endophallic sclerites dark brown.

Morphology: Head: H/MxW: 3.71; compound eyes mid-sized, H/D: 2.7; IO/MxW: 0.19. Outer cusp of lacinial tips broad, with six denticles. Forewings: L/W: 0.49. Pterostigma wider in the middle: lp/wp: 1.57, areola postica tall, almost reaching M, apex rounded: al/ah: 1.22. Hindwings: l/w: 0.49. Hypandrium ( Fig. 42 ) as described in diagnosis. Phallosome ( Fig. 41 ), with endophallic sclerites as described in diagnosis, external parameres somewhat widened, with clearly sclerotized internal area, bearing pores. Paraprocts ( Fig. 40 ) triangular, with a dense field of setae and macrosetae posteriorly; sensory fields with 27 trichobothrias on basal rosettes. Epiproct ( Fig. 40 ) slightly convex anteriorly, rounded posteriorly, setae and macrosetae as illustrated.

Material studied. Holotype male. COLOMBIA. Putumayo. Puerto Asís, Huitoto trail, 00° 23’ 21.01’’ N: 76° 31’ 41.87’’ W, 264 m, 27.VII.2014. Led light trap in forest canopy. J. Panche. MUSENUV slide code 29955 . Paratypes, 2 males, same locality and collector, 18.II.2015. Types deposited in the Entomological Museum of the Universidad del Valle (MUSENUV), in Santiago de Cali, Colombia .

Etymology. This species is dedicated to the Tikunas, a large Amazonian ethnic group, distributed in the Amazonian trapeze between Colombia, Peru and Brazil. The name means “men painted in black” because of their habits of painting their entire bodies with the fruit of the huitoto tree.
