Platyplastinx duckhousei sp. nov.

( Figs. 3 A–B View FIGURE 3 A – B ; 4 A–D)

Type material. Holotype [adult male]: BRAZIL, Amazonas, Manaus, Rodovia Amazonas 0 10, Km 26, Reserva Ducke, IX. 2001, J. F. Vidal ( MZFS). Paratype. Male, same data as holotype ( INPA).

Diagnosis. Adult. Interocular suture inverted U-shaped; R 2 + 3 short, approximately 0.07 times the length of R 2; hypandrium bilobed, lobes with few bristles at apex; ejaculatory apodeme trapezoidal, with rounded corners; paramere trapezoidal, longer than wide, with aslope distal margin; cercus piriform, with one apical tenaculum feathered and 16–18 short rod-like accessory tenacula dispersed along the distal half of the ventral surface; hypoproct with elongated and globular apex.

Description. Adult Male: Eyes separated by less than one facet diameter; interocular suture inverted Ushaped; eye bridge with 4 facet rows. Ratios of palpus segments 10: 19: 20: 23. Wing membrane darkened in apical half, except in small apical areas between wing veins; dark spots on base of R 5 and radial fork; R 2 + 3 short, approximately 0.07 times the length of R 2; radial fork basal to medial fork. Hypandrium bilobed, lobes with few bristles at apex; gonostylus longer than gonocoxites, nearly straight, ending beyond the aedeagus and paramere; ejaculatory apodemes trapezoidal; aedeagus fingerlike, 1.5 times longer than the length of ejaculatory apodeme; paramere trapezoidal, longer than wide, with aslope distal margin; epandrium wider than long, with bristles distributed near the apical margin; cercus with one apical feathered tenaculum and 16–18 short, rod-like accessory tenacula dispersed along the distal half of the ventral surface; hypoproct with well-distributed microtrichia, elongated, with globular apex.

Adult Female: Unknown.

Distribution. Know only from the type locality.

Etymology. The specific epithet is in honor of the great entomologist and specialist in Psychodidae, Dr. Derek Duckhouse (in memoriam).

Comments. P. duckhousei is similar to P. plumaris by the shape of their male terminalia. The new species differs from P. plumaris by the absence of a dark spot at the base of the medial fork, by the aedeagus not having a circular base, and by the number of short rod-like accessory tenacula, 16–18 in P. duckhousei but only 6–8 in P. plumaris .
