Jenopappius Fernandez-Triana gen. n.

Type species.

Jenopappius magyarmuzeum Fernandez-Triana & Boudreault, here designated.

Diagnostic description.

Clypeus relatively small and bulging (Figs 18B , 20B ). Tentorial pits relatively large. Notauli marked by coarser sculpture than rest of anteromesoscutum (partially visible in Figs 20F , 21C ). Scutoscutellar sulcus deep and with strong crenulae (Figs 18E , 20F , 21C ). Propodeum without areola, but with median longitudinal carina obscured by surrounding sculpture (Figs 20F , 21E ). Fore wing with four-sided areolet (second submarginal cell). Metacoxa relatively short (not surpassing posterior margin of T2). Metatibial spurs relatively short (less than half length of first segment of metatarsus) (Figs 20A , 21A ). T1 longer than wide, mostly sculptured with strong longitudinal striae, but with anteromedian depression (Figs 18F , 20E , 21B, E ). T2 rectangular, as long as or longer than T3, with strong longitudinal striation and a central, smooth area (median field) which is slightly more elevated than rest of tergite and it is narrowing towards posterior margin (Figs 18F , 19A, B , 20E , 21B, E ). Hypopygium inflexible and not pleated. Ovipositor sheaths very short (Figs 18A , 20A ).

Putative autapomorphies and potentially related genera.

Jenopappius clearly belongs to the Microplitini (sensu Mason 1981). It resembles Microplitis but with a strongly sculptured and rectangular T2 and a rather unique pattern of T1. Also, some Alloplitis may have somewhat similar sculpture of either T1 or T2 (but the shape of those tergites in that latter genus is very different, and the propodeum is fully areolated with strongly raised carinae). The combination of sculptured propodeum without areola, anteromedian depression of T1, and strong sculpture of T1-T2 are very unusual and will separate Jenopappius from any other known genera of Microplitini and indeed Microgastrinae .

Biology.

Host unknown.

Distribution.

All known species are found in the Afrotropical region (Democratic Republic of Congo, Kenya, Republic of Congo, Rwanda).

Molecular data.

A total of 11 DNA barcodes are available, from Jenopappius magyarmuzeum . All sequences cluster together in BIN BOLD:AAH1374, and are different by 14.2 % of the closest Microgastrinae in BOLD (based on a Neighbor Joining tree built with 35,000+ Microgastrinae sequences available in BOLD as of January 2018).

Etymology.

The genus name refers to and honors the Hungarian braconid expert Jeno Papp, in recognition of his significant contributions to the knowledge of Braconidae of the world, and his work on Palearctic Microgastrinae . The gender of the genus is neuter.

Species.

We recognize three different species, two previously described by de Saeger (1944) and a new one described below. They can be separate using the following key.

Blue arrow shows tergite 1 narrowing (A) or widening (B) towards posterior margin. Red arrow shows end of lateral margin of tergite 1 and beginning of lateral margin of median area of tergite 2 to be almost continuous (A) or end of lateral margin of tergite 1 and beginning of lateral margin of median area of tergite 2 to be clearly separate (B).
