Figs 35 View Figure 35 , 36 View Figure 36 , 42A, B View Figure 42
Diagnosis.
Head, in lateral view (Fig. 35C View Figure 35 ), crown-face transition thin. Pygofer (Fig. 35G View Figure 35 ) without processes. Subgenital plate, in ventral view (Fig. 35H View Figure 35 ), narrow and long, inner and outer margins straight, slightly divergent toward apex. Style, in lateral view (Fig. 35K View Figure 35 ), apex forming conspicuous process very thin and acute, directed posterodorsad. Aedeagus (Fig. 35L, M View Figure 35 ) apodemal process sigmoid, elongated and narrow, almost as long as shaft; shaft very long, cylindrical, basal portion curved, posterior portion almost straight; apex truncated, with pair of processes directed dorsally bearing small spiniform process near base.
Measurements.
Total length: holotype male 9.9 mm; paratype, female (n = 1) 10.5 mm.
Coloration.
Head and thorax (Figs 35A, B View Figure 35 , 42A, B View Figure 42 ) yellowish brown. Crown (Fig. 35A View Figure 35 ) with pair of rounded black spots near posterior margin, behind ocelli. Face (Fig. 35B View Figure 35 ) without maculae. Pronotum (Fig. 35A View Figure 35 ) with brown punctures; larger black maculae near anterior margin, behind eye; portion near anterior and lateral margins yellowish; posterior margin with black transverse band. Mesonotum (Fig. 35A View Figure 35 ) with three pairs of yellow spots: two pairs near anterior margin and one near scutoscutelar suture; black maculae near lateral angles and median portion. Scutellum (Fig. 35A View Figure 35 ) with pair of large yellow spots; apex black. Forewing (Fig. 35D View Figure 35 ) strongly marked by dark-brown mottling and yellow maculae; membrane translucent brown; veins dark-brown. Metatibia (Fig. 35C View Figure 35 ) with cucullate bases of setae blacks.
Description.
Head, in dorsal view (Fig. 35A View Figure 35 ), transocular width 8.3 tenths of humeral width of pronotum. Head, in frontal view (Fig. 35B View Figure 35 ), frons 1.3 × longer than wide; clypeus 1.3 × longer than wide; lateral margins parallel. Head, in lateral view (Fig. 35C View Figure 35 ), crown-face transition thin, with 5 transverse striae. Forewing (Fig. 35D View Figure 35 ) with appendix developed, as wide as first apical cell maximum width. Protibia AD row without differentiated setae. Metatibia PD, AD and AV rows with 23-24, 12 and 16-17 macrosetae respectively. Metatarsomere I 4 × longer than apical width; inner row of the ventral surface with 8-10 setae; pecten with 4 platellae. Metatarsomere II pecten with 2 platellae. Other characteristics as in generic description.
Male terminalia.
Sternite VIII (Fig. 35E View Figure 35 ) 1.5 × wider than long, lateral margins parallel; posterior margin with deep rounded excavation. Valve (Fig. 35F View Figure 35 ) 2.5 × wider than long; posterior margin with median third excavated; in lateral view, strongly convex. Pygofer, in lateral view (Fig. 35G View Figure 35 ), 2 × longer than maximum height; anteroventral margin rounded; posterodorsal and posteroventral margins straight and slightly convergent posterad; apex slightly tapered and rounded. Subgenital plate, in ventral view (Fig. 35H View Figure 35 ), narrow and long, 6 × longer than wide, maximum width near apical portion; inner and outer margins straight, slightly divergent toward apex; apex rounded. Connective (Fig. 35I View Figure 35 ) slender. Style, in lateral view (Fig. 35K View Figure 35 ), blade moderately wide near basal half; ventral margin slightly produced ventrally and serrated, bearing small dentiform tooth; apex forming conspicuous process, very thin and acute, directed posterodorsad. Aedeagus (Fig. 35L, M View Figure 35 ) dorsal apodeme developed, dorsal margin slightly excavated, lateral margins projected dorsolaterally; apodemal process sigmoid and narrow, almost as long as shaft; apex subacute; shaft very long, cylindrical, basal portion curved, posterior portion almost straight; apex truncated, with pair of processes directed dorsally, posterior margin bearing small spiniform process near base. Other characteristics as in generic description.
Female terminalia.
Sternite VII (Fig. 36A View Figure 36 ) 1.5 × wider than long; posterolateral angles more produced than the posterior margin; posterior margin excavated, bearing a inconspicuous median lobe. Pygofer (Fig. 36A, B View Figure 36 ) 1.9 × longer than maximum height; apex rounded. First valvifer (Fig. 36C View Figure 36 ) as long as wide; lateral margins straight. First valvula (Fig. 36C View Figure 36 ) 5.4 × longer than wide, basal portion strongly produced anterad; base slightly curved ventrally. Second valvula (Fig. 36E View Figure 36 ) 3.7 × longer than wide; dorsal protuberance subacute. Gonoplac (Fig. 36G View Figure 36 ) 3.4 × longer than wide. Other characteristics as in the diagnosis of the genus.
Etymology.
The new species name refers to the similarity to E. tenuemarginata sp. nov.
Material examined.
Holotype male: Brazil: Rondônia: "Vilhena, RO\ 27/XII/1986 \ C. Elias, leg.\ Polonoroeste" (DZUP) . Paratype: 1♀, same data as holotype except 19/XI/1986 (DZUP) .
Remarks.
Effossana assimulata sp. nov. was found as sister of E. tenuemarginata sp. nov. with moderate branch support (SR = 65), supported by a single homoplastic character, 8:1, crown-face transition in lateral view thin. The new species is similar to E. tenuemarginata sp. nov., and two other species not included in the phylogenetic analysis ( E. gatuna comb. nov. and E. scapa comb. nov.) by the shape of the aedeagus with shaft slender and very long, but not forming a conspicuous curvature at base like a ring. Effossana assimulata sp. nov. is easily recognized by the style (Fig. 35K View Figure 35 ) with apex forming a slender process, thin and acute, directed posterodorsad; the aedeagus (Fig. 35L, M View Figure 35 ) with apodemal process sigmoid; and the shaft with pair of apical processes with a small spiniform process near base.
