REMARKS. This is a small to medium, unmarked species of Herrera   . The complete lack of markings on the body makes the species easy to distinguish among the Bolivian Herrera   species.

ETYMOLOGY. The name is in reference to the unicolorous body (L., concolor   , colored uniformly) without markings.

DESCRIPTION. Ground color pale yellow-green. Green may predominate in fresh specimens as there is some green on the costal margin, posterior of some abdominal segments and laterally on abdominal segment 9 in one specimen.

Head. Head slightly wider than mesonotum, ground color without markings. Ocelli rosaceous and ochraceous, rosaceous or ochraceous in paratypes. Eyes castaneous, dark castaneous or ochraceous in some paratypes, short and long golden pile posterior to eye. Ventral head ground color. Postclypeus centrally sulcate from anterior to posteroventral margin to around apex, with ten transverse grooves, short silvery pile on lateral margin. Anteclypeus ground color. Long white pile on ventral head, ventroposterior postclypeus and anteclypeus. Mentum ground color, labium ground color with piceous tip, reaching to anterior of hind coxae. Proximal half of scape and proximal annular mark on pedicel ground color, remaining antennal segments testaceous.

Thorax. Dorsal thorax ground color. Pronotum unmarked, sparse piceous pile along anterior. Pronotal collar ground color. Mesonotum ground color, unmarked, slight mottling in lateral sigillae where muscles attached internally in two paratypes. Metanotum ground color. Short golden pile between anterior arms of cruciform elevation, posterior to anterior arms of cruciform elevation and radiating from dorsoposterior metanotum, long golden pile on posterior half of lateral mesothorax, posterior mesothorax, radiating from posterior wing groove, and on lateral metanotum. Ventral thoracic segments ground color with long and short silvery pile.

Wings. Fore wings and hind wings hyaline, with eight and six apical cells respectively. Venation ground color, becoming piceous distally, except piceous anal vein 2 + 3, pterostigma present. Basal membrane grayish margined with piceous. Hind wing venation ground color becoming piceous distally. Basal half of anal cell 3 gray, anal cell 2 along proximal anal vein 3 to curve, anal cell 3 along proximal half of anal vein 3 margined with gray.

Legs. Ground color except piceous tips of pretarsal claws, with long golden pile radiating from legs. Fore femora with proximal spine longest and most oblique, secondary spine only slightly angled, shorter than tertiary spine, tertiary spine angled less than primary spine, intermediate in length and curving to tip, and very small apical spine emerging from distal base of tertiary spine. Spines with castaneous tips. Tibial spurs and comb ground color with castaneous tips.

Operculum. Female operculum ground color with curved lateral margin, rounded posterolateral margin to straight posterior margin, medial margin acutely angled with rounded terminus reaching medially to middle meracanthus not covering tympanal cavity, covered with and radiating long golden pile. Female meracanthus broadly triangular, pointed, extending beyond posterior margin of operculum, ground color with radiating long golden pile.

Abdomen. Tergites ground color covered with golden pile, more dense laterally, longer pile on lateral tergites. Female abdominal segment 9 ground color, dorsal beak darker in some paratypes, golden pile dorsally and radiating long golden pile ventrally and laterally. Posterior margin of abdominal segment 9 sinuate. Sternites and epipleurites ground color with short and long golden pile. Female sternite VII with deeply curved notch almost reaching anterior margin, margin of notch extending to point posteriorly producing small triangular extension beyond lateral posterior margin, lateral posterior margin curving anteriorly to psoterolateral terminus.

Genitalia. Female gonapophyses VIII and IX castaneous with piceous tip, gonapophysis X castaneous extending beyond dorsal beak with radiating golden pile. Gonocoxite IX ground color. Anal styles castaneous, about half as long as dorsal beak.

Male is unknown.

MEASUREMENTS (MM). N = six females, mean (range). Length of body: 19.73 (18.95–20.7); length of fore wing: 22.89 (22.0–23.5); width of fore wing: 7.90 (7.6–8.35); length of head: 3.26 (3.1–3.35); width of head including eyes: 6.08 (5.8–6.35); width of pronotum including suprahumeral plates: 6.83 (6.6–7.1); width of mesonotum: 5.91 (5.75–6.05).

DIAGNOSIS. Herrera concolor   n. sp. can be distinguished from all known species of Herrera   except H. criqualicae Boulard, 1986   n. comb. by the lack of markings on the unicolorous body. Herrera criqualicae   can be distinguished by the infuscation on the fore wing apex margin and darker lines of infuscation in the apical cells of the fore wing, the wider and longer medial extension of the female timbal, the longer dorsal beak, and the lack of the medial notch forming a triangular extension beyond the posterior margin of female sternite VII found in this species. Other similar species are Carineta spoliata ( Walker, 1858a)   and C. viridicollis ( Germar, 1830)   but the head is slightly wider than the mesonotum in this new species that distinguishes it from the species of Carineta   and places it in the genus Herrera   .

DISTRIBUTION. The species is known only from the type series collected in eastern Bolivia and western Brazil.
