Graphocaecilius mockfordi n. sp.

( Figs 1–10 )

Diagnosis. Differing from G. interpretatus Roesler (1940) , G. p i c t u s Mockford & Sullivan (1986), and G. trypetoides Enderlein (1900) , in having the forewings hyaline, lacking pigmented areas. It differs from G. enderleini Williner (1949) , in lacking a brown spot at the fused Rs-M, and in having the areola postica taller and narrower. It differs from G. lacteus ( Williner, 1949) , in having the fused Rs-M shorter, and in having the areola postica distinctly narrower. It differs from G. peruvianus Mockford & Sullivan (1986) , in having the hypandrium with a well defined posterior projection, in having the phallosome anteriorly unstemmed, in having the endophallus distinctly different (compare Fig. 4 in this paper with Fig. 21 in Mockford & Sullivan, 1986), and in lacking the broad, rugose, clunial projections over the area of the paraprocts. Differing from G. v a r t yi Turner (1984), in lacking a crescent shaped, clear membranous area in the mid clunium and projections over the area of the paraprocts, and in the shape of the hypandrium and endophallic sclerites.

Male. Color. Body tawny brown, compound eyes black, legs yellow, forewings pale yellowish; hindwings almost transparent. Tergal lobes of meso- and metathorax pale brown, abdomen creamy. Clunial projection brown.

Morphology. As in diagnosis, plus the following: head vertex almost straight; upper border of compound eyes below the level of the vertex, with interommatidial setae ( Fig. 2 ). Forewing L/W: 2.49, with setae in the veins except for Cu2; lp/wp: 3.05, pterostigma without setae in the membrane, areola postica triangular ( Fig. 1 ). Hindwing ( Fig. 1 ), L/W: 2.67. Hypandrium ( Fig. 5 ), distinctly projected posteriorly. Arms of the phallosome aedeagal arch proximally wide; endophallus with minute denticles and two groups of sclerites: the anterior one with two denticles, and the posterior with seven, disposed as illustrated ( Fig. 4 ). External parameres bearing pores distally ( Fig. 4 ). Posterior border of clunium projected over the area of the epiproct, covering about one fifth of its length ( Fig. 3 ). Clunium not projected over the area of the paraprocts ( Fig. 3 ), these broad, elongate, with setae as illustrated; sensory fields with 16–19 trichobothria in basal rosettes. Epiproct ( Fig. 3 ) anteriorly straight, posteriorly rounded, with macrosetae as illustrated.

Female. Color. Same as the male ( Fig. 26 ); abdomen creamy, with transverse, subcuticular pale brown bands. Clunium brown; epiproct pale brown, paraprocts creamy with pale brown spots. Subgenital plate pale brown with a median apical creamy longitudinal band ( Fig. 9 ).

Morphology. Head as in the male, compound eyes smaller than in male, below the level of the vertex ( Fig. 7 ). Forewing L/W: 2.59. Pterostigma, lp/wp: 3.33. Areola postica triangular, not slanted posteriorly ( Fig. 6 ). Hindwing L/W: 2.74 ( Fig. 6 ). Subgenital plate ( Fig. 9 ), densely setose, with sides converging to a straight posterior border; a longitudinal slender band next to posterior border; IX sternum ( Fig. 10 ) well developed, slightly pigmented, with a rectangular anterior projection. Gonapophyses ( Fig. 10 ), with v1 elongate, slender, joined to clunium; v2 +3 with anterior half hyaline, posterior half pigmented, slightly projected distally, bearing a row of setae along posterior border. Paraprocts ( Fig. 8 ) twice as long as wide, rhomboid, with setae as illustrated; sensory fields with 14 trichobothria issuing from basal rosettes ( Fig. 8 ). Epiproct broadly triangular, anteriorly convex, setae as illustrated ( Fig. 8 ).

Measurements (in microns). FW: 2850, HW: 2195, F: 650, T: 1100, t1: 350, t2: 125, ctt1: 17, Mx 4: 160, f1: 580, f2: 360, f3: 300, f4: 260, f5: 170, f6: 160, f7: 135, f8: 120, f9: 105, f10: 100, f11: 110, IO: 560, D: 180, d: 100, IO/d: 5.60, PO: 0.55.

Etymology. This species is dedicated to Dr. Edward L. Mockford, of Illinois State University, in recognition to his many and fundamental studies on the taxonomy of ‘Psocoptera’, including his foundational work on the taxonomy of the Graphocaeciliine psocids, in collaboration with Mr. D. M. Sullivan, formerly of Illinois State University.
