Ganguilus veniae sp. n.

( Figs 37–40 )

Diagnosis

A pale yellow species with characteristic long white erect bristles on forelegs and thorax. Forewing with two black dots and numerous pale brown markings ( Fig. 37 ).

Description

Size (mm). Forewing: 3 28, Ƥ 27; hind wing: 3 24, Ƥ 23; length of body: 3 25, Ƥ 21; length of abdomen: 3 16, Ƥ 14.

Head. Entirely yellow except for two brown markings behind and below antennal toruli in females, these markings faint in males. Frons and vertex with conspicuous white setae. Maxillary and labial palps yellow, palpimacula black.

Thorax. Entirely yellow, with long erect white setae on pronotum, along hind margin of mesoprescutum, on discal area of mesoscutum and at posterior angles of mesoscutellum. Pleurites with downwardly orientated straight white setae on mesoepisternum and mesokatepisternum.

Legs. Foreleg: coxa with long white setae; trochanter with white and a few black setae on dorsal surface longer in males; femur yellow with a brown spot on ventral surface below apical reticular membrane and a brown stripe on apical half of anterior surface, this stripe more clearly delimited in males, a tuft of very long erect white setae at base on dorsal surface and other conspicuous white setae on ventral surface and apically on dorsal surface; tibia with main setae white, anterior surface brownish with a brown stripe on apical half in males; tibial spurs as long as T1+2; tarsus yellow; claws pale brown. Middle leg: coxa with white downwardly orientated setae; trochanter as in foreleg; femur with anterior surface brown, main erect setae white; tibia with anterior surface brown, main erect setae black; tibial spurs as long as T1+2. Hind leg: coxa bearing a row of downwardly orientated straight white setae; trochanter with only a few setae; femur brownish except on ventral surface, femoral brush of male bearing 104 setae; tibia yellow; tibial spurs curved apically, extending to middle of T2; tarsus yellow; claws pale brown.

Wings. Narrow with acute apex. Veins pale with C, SC and R darker. Forewings with two black spots, one on the fourth cross vein between MP and CuA and another at extremity of A1, other markings pale brown. Five crossveins between R and MP before origin of RS; RS arising beyond CuA fork. Hind wings very slightly maculated apically. Stigma brown and yellow.

Abdomen. Brownish with sternites III to VII darker. Ectoprocts oval, slightly enlarged ventrally ( Fig. 37 ). Parameres short and divergent. Pulvini well developed and quite different from all other species. ( Figs 39 & 40 ). Terminalia of female without gonapophyseal plate.
