Effossana intrinseca sp. nov.

Figs 39 , 40 , 43C, D

Diagnosis.

Head, in lateral view (Fig. 39C ), crown-face transition moderately thick Pygofer, in dorsal view (Fig. 39g ), with acute subapical process, directed inward. Style, in lateral view (Fig. 39K ), with blade very narrow near base and strongly widened towards apex; apex truncated with thin and acute process directed dorsally. Aedeagus (Fig. 39L ) with shaft very long, basal portion strongly curved forming wide ring.

Measurements.

Total length: holotype male 8.6 mm; paratypes, males (n = 4) 8.6-9.2 mm, females (n = 2) 9.3-9.4 mm.

Coloration.

Head and thorax yellowish brown. Crown (Fig. 39A ) with coronal suture black. Face (Fig. 39B ) gena yellow, brown markings near subgenal suture, ventral and inner margins of eye. Pronotum (Fig. 39A ) with brown punctures, pair of elongated and oblique black maculae behind ocelli, near anterior margin; posterior margin with black transverse band; proepimeron (Fig. 39C ), with black band below lateral carina. Mesonotum (Fig. 39A ) with yellow markings, pair of black ring-shaped maculae near lateral angles and pair of rounded black spots, near scutoscutellar suture. Scutellum (Fig. 39A ) black with pair of large yellow spots. Forewing (Fig. 39D ) with dark-brown mottling; membrane translucent light yellow; veins brown outlined by dark brown. Metatibia (Fig. 39C ) with cucullate bases of setae blacks.

Description.

Head, in dorsal view (Fig. 39A ), transocular width 8.1 tenths of humeral width of pronotum. Head, in frontal view (Fig. 39B ), frons 1.4 × longer than wide; clypeus 1.4 × longer than wide; lateral margins parallel. Head, in lateral view (Fig. 39C ), crown-face transition moderately thick, smooth medially and with few striae near of eye. Forewing (Fig. 39D ) with appendix reduced, narrower than width of first apical cell. Protibia with AD row with 2-4 differentiated setae. Metatibia PD, AD and AV rows with 23-24, 12-13 and 16-18 macrosetae respectively. Metatarsomere I moderately elongated, about 3 × longer than apical width; inner row of ventral surface with 5-6 setae; pecten with 6-7 platellae. Metatarsomere II pecten with 3 platellae. Other characteristics as in generic description.

Male terminalia.

Sternite VIII (Fig. 39E ) 1.4 × wider than long, lateral margins rounded; posterior margin with median third deeply excavated, bearing short median projection. Valve (Fig. 39F ) 2.5 × wider than long; posterior margin narrowly excavated; in lateral view, strongly convex. Pygofer, in lateral view (Fig. 39G ), 2.2 × longer than maximum height; anteroventral margin sinuous; posterodorsal and posteroventral margins slightly rounded; apex narrowed and rounded; in dorsal view (Fig. 39g ), with acute subapical process, directed inward. Subgenital plate, in ventral view (Fig. 39H ), elongated, 3.4 × longer than wide, maximum width near half length; inner margin straight; outer margin broadly rounded; apex rounded. Connective (Fig. 39I ) with thin arms. Style, in lateral view (Fig. 39K ), with blade very narrow near base and strongly widened towards apex; dorsal margin excavated; ventral margin straight, with apical third serrated; apex truncated and very wide, with thin and acute process directed dorsally. Aedeagus (Fig. 39L, M ) dorsal apodeme reduced, dorsal margin excavated, lateral margins not projected laterally; apodemal process elongated and curved dorsally, dorsal margin slightly excavated medially, apex slightly broadened and rounded; shaft cylindrical and very long, basal portion strongly curved forming wide ring, portion after the ring straight; apex slightly twisted laterally, with two pair of processes directed dorsally: apical pair very short, near lateral margins and subapical pair 4 × longer than the apical pair, arising from the posterior surface. Other characteristics as in generic description.

Female terminalia.

Sternite VII (Fig. 40A ) 2 × wider than long; posterolateral angles produced as far as posterior margin; posterior margin deeply excavated each side of rounded median lobe which occupies more than median third. Internal sternite VIII membranous. Pygofer (Fig. 40A, B ) 1.9 × longer than maximum height; apex rounded. First valvifer (Fig. 40C ) sub-rectangular 1.6 × wider than long; dorsal margin straight; posterior margin rounded. First valvula (Fig. 40C ) 4 × longer than wide. Second valvula (Fig. 40E ) 4 × longer than wide; dorsal protuberance rounded. Gonoplac (Fig. 40G ) 3.7 × longer than wide. Other characteristics as in the diagnosis of the genus.

Material examined.

Holotype male: Brazil: Mato Grosso: “Cáceres, MT\ 27/III/1985 \ C. Ellias leg.\ Polonoroeste", "Dpt° Zool\ UF-Paraná” (DZUP) . Paratypes: 2♂, 1♀, same data as holotype ; 1♂, same data as holotype except 20.XII.1984 (DZUP); 1♀, same data as holotype except 14.I.1985 (DZUP).

Etymology.

the new species name refers to the process of pygofer directed inward.

Remarks.

Effossana intrinseca sp. nov. can be distinguish from E. circumnota sp. nov. by the pygofer (Fig. 39g ) with a subapical process directed inward; the style (Fig. 39K ) with ventral margin of blade without process, and the apex truncated and very wide, forming a thin and acute process directed dorsally.
