Type material.

Holotype. French Guiana • Female, CNC; Montagne de Kaw, Relais Patawa ; ii.1999; A. E. I. Guyane-J. Cerda leg.; Malaise trap; Voucher code: CNC 491966 . Paratypes. Brazil • 2 Females, CNC; CNCHYM 00125 , CNCHYM 00126 . French Guiana • 1 Female, CCDB; CCDB- 07375 B 04 .

Diagnostic description.

T 1 almost entirely smooth (only weak punctures near posterior margin); T 1 more or less parallel-sided; T 2 entirely smooth and shiny; T 2 sub-quadrate, its width at posterior margin <1.9 × its length centrally; ovipositor sheath 2.0 × as long as metatibia length; metatrochanter black, metatrochantellus yellow-orange; mesofemur and metafemur entirely yellow; body length: 4.10–4.20 mm; fore wing length: 4.20–4.30 mm; ovipositor sheath length: 3.00– 3.20 mm. Among all species within the carlosmanuelrodriguezi group, it can be recognized by the combination of its body size and mesofemur and metafemur coloration, as well as distinctive DNA barcodes.

Distribution.

Brazil (MG), French Guiana.

Biology.

No host data available.

DNA barcoding data.

BIN BOLD: ABZ 4155 (15 sequences, 15 barcode compliant), but see notes below. The paratype from French Guiana has a full barcode, the two Brazil paratypes have partial sequences (363 and 164 bp).

Etymology.

Named after Hélène Dumas (la Ciotat, France), in recognition for her efforts filming insects, especially Microgastrinae wasps in France. Hélène is the daughter of Frédéric Dumas, who was a member of the commander Jacques-Yves Cousteau’s team.

Notes.

The material we have studied included three specimens deposited in the CNC, one from French Guiana (holotype) and two paratypes from Brazil. They match very closely with the photo in BOLD of a different barcoded specimen from French Guiana, deposited in the CCDB and collected in a locality close to that of the holotype. Although we have not been able to examine that specimen, its body size (as indicated in the scale bar of the photo in BOLD), matches closely with the CNC specimens. Body length is a relevant and diagnostic feature for this new species; based on that we consider all those specimens (from French Guiana and Brazil) to be conspecific. The full sequence of the CCDB specimen corresponds to the same BIN than that of the species D. carlosmanuelrodriguezi , from Costa Rica. However, that BIN contains more than one species, as mentioned in the original description of D. carlosmanuelrodriguezi ( Fernandez-Triana et al. 2019: 100) . Those authors indicated that, in addition to D. carlosmanuelrodriguezi , there were four other undescribed species from Costa Rica (ACG), and here we account for an additional one from South America. The full barcode sequence of D. helenedumasae (paratype from French Guiana) is> 1.3 % bp different from the closest ACG species (which remains undescribed and with interim name of Dolichogenidea Janzen 156 in BOLD), and the other ACG species within this BIN are farther apart. We consider the molecular differences and the body size difference as sufficient to recognize D. helenedumasae as a distinct species from the ACG species.
