González-Obando, Ranulfo, Carrejo-Gironza, Nancy & García, Alfonso N., 2017, New species of Colombian Triplocania Roesler (Psocodea: ‘ Psocoptera’: Ptiloneuridae), Zootaxa 4336 (1), pp. 1-113 : 89-93

Triplocania furcatoides n. sp.

( Figs 305–316 )

Diagnosis. Closely related to T. furcata New, from which it differs in having the outer processes of the central sclerite of the hypandrium longer and almost straight, and in having the inner processes of the central sclerite of the hypandrium longer and distinctly curved inwards ( Fig. 308 ); the phallosome, although on the same structural plan as L. furcata , differs from it in details of the endophallic sclerites (compare Fig. 310 with Fig. 110 in New, 1972), particularly the posterior pair, straight and divided posteriorly in T. furcatoides ( Fig. 310 ). Unlike T. furcata (the female of which is described below) the posterior area of the IX sternum has finer longitudinal grooves, coarser in the former, and the proximal heel of v2 +3 is distinctly slender, not stout as in T. furcata (compare Fig. 316 with Fig. 364 below).

Male. Color (in 80% ethanol). Body brown. Head dark brown, pattern ( Fig. 307 ); compound eyes brown; ocelli hyaline, with ochre centripetal crescents. Genae brown. Antennae and maxillary palps brown. Tergal lobes of meso- and metathotax brown. Thoracic pleura brown, with reddish brown spots. Coxae and trochanters cream; femora, tibiae and tarsi brown. Wings almost hyaline. Forewing smoked proximally ( Fig. 305 ). Abdomen cream, with irregular subcuticular areas brown; clunium brown; epiproct and paraprocts pale brown, with subcuticular spots yellowish-brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 307 ): H/MxW: 1.55, H/D: 2.02, IO/MxW: 0.60, MxW/IO: 2.82. Abundant interommatidial setae. Vertex almost in line with the upper border of the compound eyes. Outer cusp of lacinial tip broad, with five denticles. Mx4/Mx2: 1.19. Forewings ( Fig. 305 ): L/W: 2.62. Pterostigma: lp/wp: 4.43, with setae in the membrane; areola postica: la/ha: 2.42, slightly slanted posteriorly. Hindwings ( Fig. 306 ): l/w: 3.13. Hypandrium ( Fig. 308 ), central sclerite convex anteriorly, posteriorly with a median, acuminate, posterior process, with two acuminate processes on each side. Lateral sclerites small, unpigmented. Phallosome ( Fig. 310 ) with side struts independent, V-shaped, widely fused posteriorly to external parameres, distally rounded, sclerotized, with a field of short spines. Anterior endophallic sclerites slender, broadly M-shaped; mesal endophallic sclerite with outer arms slender, curved, inner arms straight, directed posteriorly, narrowing distally; posterior sclerites long, with a short subapical tooth on outer border ( Fig. 310 ). Paraprocts oval ( Fig. 309 ), posterior border widely rounded, distally with abundant medium and large setae, one macrosetae next each sensory field, these with 28 trichobothria on basal rosettes. Epiproct wide ( Fig. 309 ), rounded posteriorly, a semi-elliptic protuberance mesally, setae as illustrated.

Female. Color (in 80% ethanol). Body, legs and wings as in the males. Pigmented area of subgenital plate Ushaped, arms wide; IX sternum cream, gonapophyses brown, mottled cream; clunium brown; paraprocts and epiproct pale brown.

Morphology. As in diagnosis, plus the following: Head ( Fig. 313 ): H/MxW: 1.50; H/D: 2.31, MxW/IO: 2.21, IO/MxW: 0.70. Vertex above the level of the compound eyes. Outer cusp of lacinial tip broad, with five denticles. Mx4/Mx2: 1.43. Forewings ( Fig. 311 ): L/W: 2.56, pterostigma: lp/wp: 3.91; areola postica la/ha: 2.73. Hindwings ( Fig. 312 ): l/w: 3.04. Subgenital plate ( Fig. 314 ) with a median, pointed, posterior process, bearing a setal field. Gonapophyses ( Fig. 316 ): v1 elongate, tapered distally, acuminate, with microsetae widely distributed in the two distal thirds; v2 +3 wide basally, with slender heel, a mesal protuberance on inner border, a row of four macrosetae on v2; distal process stout, almost straight, distally blunt, with microsetae. Paraprocts ( Fig. 315 ) broadly triangular, posteriorly rounded, setae as illustrated; sensory fields with 28 trichobothria on basal rosettes. Epiproct wide, slightly bilobed anteriorly, posteriorly rounded, with abundant setae on distal half, as illustrated ( Fig. 315 ).

Measurements. FW: 3650, HW: 2700, Mx4: 243, f1: 650, f2: 520, f3: 470, IO: 420, D: 390, d: 245, IO/d: 1.71, PO: 0.63.

Etymology. The specific name refers to the proximity of this species to T. furcata New.
