(Figs. 19–20)

Mantispa ariasi Penny, 1982b: 454 ; Penny & Costa 1983: 675 (redesc.); Ohl 2004: 178 (cat.). Type locality: Brazil: Amazonas. Male holotype (INPA) studied.

Redescription, male. Vertex reddish brown, except yellow round spot behind each antenna and yellow lateral stripes that border eyes (Fig. 19d). Some specimens with the round spots fused. Head in frontal view almost completely yellow, except for central longitudinal dark brown stripe beginning between antennae and ending at labrum. Stripe generally with widen variation along its length. Labrum and clypeus yellow area slightly darker than other head sclerites (Fig. 19a). Some specimens with round yellow spot at beginning of longitudinal stripe. Mandible and palpi apices dark brown, other mouthparts reddish brown. Antenna with scape yellow ventrally and light brown dorsally, pedicel light brown, and flagellum dark brown (Fig. 19a).

Pronotum: nearly straight, in lateral view, and completely covered by setae arising directly from it surface. Length-width-ratio at maculae: 5.6–7.3. Reddish brown (Fig. 19d), some specimens with median region slightly light. Pteronotum: reddish brown; some specimens with small yellow rounded spots near wing base. Both scutella yellow (Fig. 19d) and with 8–11 pores each one. Pleural sclerites light brown with yellow spots (Fig. 19b).

Foreleg: coxa yellow, except reddish brown distally. Trochanter, tibia (except for yellow base), tarsomeres, and most femur posterior parts reddish brown. Femur posterior surface yellow near spine row (Fig. 19f); anterior surface predominantly dark reddish brown, except reddish brown extremities and spines (Fig. 19e). Mid and hindlegs yellow, except light brown coxae, trochanters and femora base (Fig. 19b). Tarsal claws with four teeth.

Forewing: length: 8.1–10.9 mm, 5–7 costal crossveins and 6–8 veins extended posteriorly from RP. Hyaline, except space between Sc and RA, and cell 1AP apex light brown. Pterostigma dark reddish brown to dark brown. Veins brown, except AP1 base light yellow (Fig. 19g). Hindwing: 4–7 costal crossveins and 7–9 veins extended posteriorly from RP. Color pattern similar to forewing, except cell 1AP apex hyaline and vein AA base light yellow (Fig. 19g).

Abdomen reddish brown dorsally and ventrally, except small yellow transverse spots at tergite ends. Pleura brown. Tergites with eight groups of pores: two posterolaterally at tergites III–IV each one with 7–8 pores in one or two curved rows; two anterolaterally at tergites IV–V each one with 15–24 pores; each group with one or two large pores or a scar between them ( Fig. 20a ).

Terminalia: ectoproct subtriangular, ventromedial lobe not sclerotized and with 8–10 stout setae ( Fig. 20b ). Sternite IX subpentagonal with posterior border rounded in ventral view ( Fig. 20c ). Gonarcus median lobe as long as or slightly longer than pseudopenis ( Fig. 20e, f ). Gonocoxite with base bent laterally in ventral view, and wider in lateral view ( Fig. 20d ). Mediuncus basal third wide in lateral view, and apex bifurcate in ventral view ( Fig. 20d, e ). Gonarcal membrane without group of spinules ( Fig. 20d, e ). Pseudopenal membrane with small scales on dorsal surface and generally as long as or slightly longer than pseudopenis ( Fig. 20d ). Hypomere as two small sclerotized marks on pseudopenal membrane ( Fig. 20d, e ).

Female. Similar to male, except pteropleura with sclerites predominantly dark brown with yellow spots at posterior border; mid and hindcoxae dark brown (Fig. 19c). Forewing length 8.5–10.3 mm.

Terminalia: ectoproct generally as long as or slightly shorter than gonocoxite ( Fig. 20i ). Sternite VIII slightly reduced laterally and ventrally; in ventral view apex rounded ( Fig. 20g ). Spermathecal duct with few bends and enlarged distally ( Fig. 20h ). Fertilization canal narrow. Capsule covered by minuscule setae ( Fig. 20h ).

Geographical data. Neotropical , with records only from Brazil ( Ohl 2004). The type series is from Amazonas state, but there are other specimens collected in the southeastern and southern regions .

Bionomy. Specimens until now collected only in January, July, October and November. Nothing is known about its biology.

Type material: Holotype male: Brazil: Amazonas : AM-010 Km 246, 15.vii.1979, Jorge R. Arias (written on a rectangular white label) INPA . Allotype female: similar to holotype. Paratypes: similar to holotype (4 ♂, 2 ♀ and 2?– INPA) ; 12.vii.1979 (2 ♂ and 1?– INPA) ; 16.vii.1979 (1 ♀ and 1?– INPA) .

Types condition: holotype with head smashed, distal area of the right fore and hindwing absent, left foreleg lost, except coxa. Allotype hindwing damaged and foreleg with fungus. Paratypes with some damage, mainly in the wings, mid and hindlegs and abdomen; mostly with fungus.
