Hemicaecilius smithersi n. sp.

( Figs. 16–17 , 22–28 )

Female. Color. Body dark brown. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Wings reddish brown, opaque, R1 dark brown ( Fig. 17 ), distinctly more pigmented than the other veins. Abdomen pale brown, with brown, transverse subcuticular rings.

Morphology. Forewing L/W: 2.67: pterostigma long, wider posteriorly, lp/wp: 1.75. Areola postica broadly triangular ( Fig. 17 ). Hindwing L/W: 2.86. Subgenital plate ( Fig. 22 ), broad, setose; pigmented area widely concave anteriorly; distal third strongly pigmented; lateral posterior projections slender, curved, acuminate, posterior border, between projections, with small pointed projections in the middle. Gonapophyses proximally broad, almost rectangular, bearing three setae; distal halves wide based, narrowing distally, acuminate ( Fig. 24 ). Ninth sternum ( Fig. 24 ): spermapore central, large, circular, inscribed in a broad, pigmented area as illustrated, flanked by one slender, longitudinal pigmented band. Paraprocts ( Fig. 23 ), almost semicircular, with a large mesal seta and a field of setae on outer margin; sensory fields with 9–10 trichobothria on basal rosettes. Epiproct ( Fig. 23 ) trapeziform, with field of setae on sides and posterior third, as illustrated.

Measurements. FW: 1900, HW: 1500, F: 317, T: 430, t1: 140, t2: 102, ctt1: 16, Mx 4: 103, f1: 194, f2: 180, f3: 148, f4: 106, f5: 60, f6: 73, f7: 58, f8: 62, f9: 55, f10: 58, f11: 65, IO: 320, D: 91, d: 160, IO/d: 2.0

Male. Color. Same as the female.

Morphology. Forewing L/W: 2.60: pterostigma long, wider posteriorly, lp/wp: 1.80 ( Fig. 16 ). Hindwing L/W: 2.78. Hypandrium ( Fig. 27 ) wide, narrow, with a stout, elongate, acuminate posterior projection in the middle. Proximal halves of claspers ( Fig. 27 ) large, broad, setose, almost elliptic; distal halves of claspers elongate, slender, curved, distally acuminate ( Fig. 27 ). Phallosome apodemes ( Fig. 28 ). Paraprocts ( Figs. 25 and 26 ) broad, setose as illustrated, bearing a mesal, long, stout, acuminate prong; sensory fields with 10–11 trichobothria on basal rosettes.

Epiproct ( Fig. 25 ), straight anteriorly, pigmented area concave posteriorly, to form two side lobes, with an unpigmented area between them, bearing a row of setae posteriorly; each lobe with a setal field as illustrated.

Measurements. FW: 2100, HW: 1632, F: 390, T: 690, t1: 235, t2: 104, ctt1: 17, Mx 4: 100, f1: 203, f2: 190, f3: 152, f4: 130, f5: 81, f6: 80, f7: 60, f8: 80, f9: 60, f10: 70, f11: 72, IO: 350, D: 100, d: 170, IO/d: 2.06.

Specimens studied. Holotype male. COLOMBIA, Valle del Cauca, Santiago de Cali, San Antonio Forest (03°29’27.7’’N: 76°37’40.9’’W, 2130 m), 25.v.2012, MUSENUV slide cod. 24023, R. González and N. Carrejo. Paratypes: 1 female, same locality as the holotype, 27.i.2012, MUSENUV slide cod. 24024, R. González, 3 females, same locality as the holotype (03°29’23.5’’N: 76°37’39.4’’W, 2142 m), 23.v.2012, MUSENUV slide cod. 24025, R. González and N. Calderón, 1 male, 3 females, same locality as the holotype, 25.v.2012, R. González & N. Carrejo. 4 males, 13 females, same locality as the holotype, 2.VI.2012, MUSENUV slide cod.24026, R. González and N. Carrejo. 1 male, 9 females, same locality as the holotype, 9.vi.2012, R. González. All the specimens taken beating tree branches and shrubs with dead leaves.

Etymology. This species is dedicated to the late Dr. Courtenay N. Smithers, in recognition of his many and important contributions to the study of Australian, New Guinean and Melanesian Psocoptera . He will always be remembered with love and gratitude by all of us who were fortunate to know him.
