Arango, Stephania Sandoval, Obando, Ranulfo González & Aldrete, Alfonso Neri García, 2016, New species of Graphocaecilius Enderlein (Psocodea: ‘ Psocoptera’: Lachesillidae) from Colombia, Zootaxa 4147 (4), pp. 421-432 : 429

Graphocaecilius turneri n. sp. Male

( Figs 21–25 )

Diagnosis. Differing from G. interpretatus , G. p i c t u s, and G. trypetoides , in having the forewings without brown spots. Differing from G. enderleini , in having the distal half of the pterostigma pigmented and in having the areola postica narrower. Differing fom G. lacteus , in having the distal half of the pterostigma pigmented, and in having the areola postica distinctly narrower. Differing from G. peruvianus , in having the phallosome anteriorly unstemmed, in the shape of the endophallic sclerites, and in lacking clunial projections over the area of the epiproct and paraprocts. Differing from G. va r t y i in the shape of the hypandrium, in lacking clunial posterior projections, and in the endophallic sclerites.

Color. Body dark brown, compound eyes black, legs yellow, forewings yellow, veins brown; pterostigma brown yellowish, hindwings hyaline, with a yellowish hue. Tergal lobes of meso- and metathorax dark brown, abdomen creamy.

Morphology. As in diagnosis plus the following: Head vertex almost straight, compound eyes prominent, upper borders above the level of the vertex, with interommatidial setae ( Fig. 22 ). Forewing L/W: 3.0. Forewing pterostigma elongate, much wider posteriorly, with setae in the membrane; lp/wp: 3.38. Areola postica triangular ( Fig. 21 ). Hindwing L/W: 2.59 ( Fig. 21 ). Hypandrium broad, setose, posterior projection with postero-lateral corners rounded distally ( Fig. 25 ). Phallosome slender, unstemmed anteriorly, three times as long as wide; external parameres slender, wide proximally, narrowing distally; aedeagal arch as illustrated; endophallus with an anterior group of minute denticles and nine posterior sclerites, disposed as illustrated ( Fig. 24 ). Posterior border of clunium not projected over the areas of paraprocts and epiproct ( Fig. 23 ). Paraprocts ( Fig. 23 ) broad, with few setae, restricted to the latero-posterior areas; sensory fields with 17 trichobothria in basal rosettes. Epiproct ( Fig. 23 ), triangular, with rounded apex, and three macrosetae in the posterior border.

Measurements (in microns). FW: 2475, HW: 1750, F: 550, T: 912, t1: 287, t2: 137, ctt1: 16, Mx 4: 170, f1: 490, f2: 335, f3: 290, f4: 220, f5: 160, f6: 145, f7: 130, f8: 120, f9: 110, f10: 105, f11: 110, IO: 300, D: 295, d: 210, IO/d: 1.43, PO: 0.71.

Etymology. This species is dedicated to Dr. Bryan D. Turner, formerly of King’s College, London, in recognition to his important contributions to the study of Neotropical ‘Psocoptera’.
