Hemerobiella periotoi Sosa View in CoL & Lara sp. nov.

( Figs. 1–3 View FIGURE 1 View FIGURE 2 View FIGURE 3 , 7 View FIGURE 7 )

Holotype, female. VENEZUELA. Lara state: Rio Claro County, Piedra del Tigre, 9º53’N / 69º19’W, 1425 m, 6.iv.2013, F. Sosa, F. Díaz & C. Martins Leg. Deposited in the MJMO.

Diagnosis. Hemerobiella periotoi sp. nov. is the only known species in the genus with a circular black mark on the second and third radial sector in the forewing ( Fig. 1 View FIGURE 1 A) and the only one in which the ninth tergite of the female is without an anteroventral lobe.

Description. Head ( Fig. 1 View FIGURE 1 B) light brown, 1.1 times as high as wide; vertex raised posteriorly, marked brown, densely covered by dark and light brown pilosity; frons slightly raised medially, bearing sparse light brown pilosity; maxillary and labial palpi light brown, unmarked; antennae light brown with 59 antennomeres covered by dark brown bristles, antennal fossa with a anterior black mark, scape 1.5 as high as wide, with lateral brown stripe.

Thorax ( Fig. 1 View FIGURE 1 C). Pronotum dark brown, longer than wide (length/smaller width: 1.7; length/larger width: 1.0), densely covered by long, light brown pilosity; mesoprescutum reddish brown medially, dark brown posteriorly; mesoscutum and metanotum dark brown dorsomedially, light brown laterally; pleural areas light brown, unmarked. Legs light brown, except for two dorsolateral rounded black spots on protibiae. Wings ( Fig. 1 View FIGURE 1 A). Forewing length:10.0 mm, 2.2 times as long as wide; costal area wide (0.3 times width of wing). Forewing hyaline and densely marked by brown infuscations, venation with alternating dark and light brown coloration, 2 rm bordered by hyaline spot, second and third radial sector marked with circular black spot medially, humeral vein strongly recurrent, pterostigma with a light brown mark on Sc margin, three radial sectors originating in basal half of wing, radial veins distinctly sinuate in the distal portion, five outer and three inner gradates. Hindwing length: 7.8 mm, 2.2 times as long as wide; membrane hyaline, venation light brown, except with brown coloration on pterostigma and forked veins along all wings, four outer and one inner gradates.

Abdomen. Male: Unknown. Female. Brown, densely covered by dark brown pilosity. Ninth tergite elongated, narrow, with slight posteroventral digitiform projection extending below ectoproct ( Fig. 2 View FIGURE 2 A). Ectoproct trapezoid in lateral view, projected posteroventrally, rounded apically, ventral margin ca. 2 times the length of the dorsal margin ( Fig. 2 View FIGURE 2 A); callus cerci with 16 trichobothria. Gonapophysis lateralis ovoid ( Fig. 2 View FIGURE 2 A–C). Spermathecal duct long, curved basally, straight towards apex; spermatheca cylindrical, roughened, curved on itself ( Fig. 2 View FIGURE 2 D–E). Subgenital plate cordiform with coriaceous membrane ( Fig. 2 View FIGURE 2 C); bursa copulatrix saccular.

Material examined. 1 female, holotype.

Etymology. The name is aimed to honor the Brazilian entomologist Nelson Wanderley Perioto, who is dedicated to the study of the Brazilian Eurytomidae (Insecta: Hymenoptera ); he is also a great friend and an enthusiastic collaborator in the study of the Brazilian Hemerobiids and Chrysopids.

Geographical distribution. Venezuela (Lara state) ( Fig. 7 View FIGURE 7 ).

Ecological notes: Hemerobiella periotoi sp. nov. was collected in the shrubbery of mature cloud forest in Lara state near border of Terepaima National Park ( Fig. 3 View FIGURE 3 ). The area has elevation of 1425 m about sea level, annual temperatures and precipitation ranging between 19–26o C and 800–2000 mm respectively.

Comparative notes. Hemerobiella periotoi sp. nov. can be separated from H. sinuata and H. oswaldi by the large black, mesal mark between the second and third radial sector on the forewing ( Fig. 1 View FIGURE 1 A) and female with subgenital plate cordiform bearing coriaceous membrane ( Fig. 2 View FIGURE 2 C). However, H. sinuata and H. oswaldi share external features and these species significantly differ in the shape of female subgenital plate, being granulate, with a U-shaped incision and two tenuous laminar pieces in H. sinuata ( Kimmins 1940) , while in H. oswaldi is spherical, with a U-shaped incision ( Fig. 6 View FIGURE 6 C) ( Monserrat 1998).
