Rostellula santacruzi View in CoL sp. nov.
(Figs 111, 156–164, 255, 256)
Etymology. This species is named after the Santa Cruz Department of Bolivia where it was collected.
Type material. Holotype – male, BOLIVIA: Santa Cruz Department, Noel Kempff Mercado National Park (near border with Brazil), Los Fierros Camp , ~ 300 m, primary forest, at leaf of small tree at night, 23–28 January 2014, A. Gorochov . Paratypes: 2 females, same data as for holotype .
Description. Male (holotype). General appearance more or less as in R. minutissima sp. nov. but with following differences: body somewhat larger; colouration completely yellowish with barely darker (i.e. having greyish tinge) head dorsum and pronotal disc, one whitish median line on dorsum of head, rose other dorsal parts of upper rostral tubercle as well as dots on dorsal part of scape and on most part of pronotum (pronotal disc with a pair of longitudinal rows from dense dots near median line in anterior half of pronotum), as well as one brown spot at base of dorsal tegminal field and without any darkish stripe in lateral tegminal field ( Figs 156–163 View Figs 156–172 ); upper rostral tubercle ( Fig. 157 View Figs 156–172 ) slightly wider than in R. minutissima sp. nov. (scape approximately two times as wide as distal part of this tubercle); pronotum with slightly higher (but also elongate) lateral lobes having widely rounded (almost obliquely truncate) posteroventral corners as well as deeper and narrower (angular) humeral notches ( Fig. 156 View Figs 156–172 ); tegmina with two branches in posterior half of normal RS, without additional longitudinal vein and with mirror somewhat shorter than in R. minutissima sp. nov. (Figs 111, 158, 159); hind wing with somewhat longer thickened distal portion of costal part ( Fig. 160 View Figs 156–172 ); last abdominal tergite with short and wide posteromedian lobe having truncate posterior edge; cercus without tooth but arcuately curved in distal half as well as having thin and acute apical part ( Figs 161–163 View Figs 156–172 ); genital plate with distal part somewhat narrowing to apex having shallowly and widely trapezoidal posteromedian notch as well as a pair of small angular projections around this notch ( Fig. 161 View Figs 156–172 ).
Female. External structure and colouration of body similar to those of male; however, rose dots on head and pronotum less distinct or indistinct, dorsal tegminal field with finely cellular yellowish venation and numerous slightly darker (yellowish grey) small membranes in cells, and abdominal apex with simple (typical of Anaulacomerina females) tergites and fusiform cerci (their apical parts barely curved upwards) as well as small triangular epiproct having rounded apex. Genital plate also small and transverse but with very small and almost obtuseangled posteromedian projection separated from rest part of this plate by very narrow, arcuate and partly membranous groove ( Fig. 255 View Figs 241–256 ); ovipositor not long, almost straight in middle and distal parts, and without denticles ( Fig. 256 View Figs 241–256 ).
Length (mm). Body: male 16.5, female 17.0–17.5; body with wings: male 27.0, female 32.0–33.0; pronotum: male 3.7, female 3.7–3.9; tegmina: male 23.0, female 23.0–24.0; hind femora: male 16.0, female 17.5–18.0; ovipositor 6.5–7.0.
Comparison. The new species differs from R. minutissima sp. nov. in the characters listed above. This species is not very related to the type species and may belong to a different subgenus of Rostellula .
