Janhalacaste Fernandez-Triana gen. n.

Type species.

Janhalacaste winnieae Fernandez-Triana & Boudreault, here designated.

Diagnostic description.

Glossa elongate (Fig. 16B View Figure 16 ). Anteromesoscutum and scutellar disc with relatively deep and close punctures. Posteromedian band of scutellum rugose (Figs 15D View Figure 15 , 16D View Figure 16 , 17C View Figure 17 ). Propodeum with complete transverse and longitudinal carinae, and with additional small carinae or striae on most of propodeum surface (Figs 14G View Figure 14 , 15G View Figure 15 , 16D, F View Figure 16 , 17E View Figure 17 ). Fore wing with small, slit-shaped areolet (as in Fig. 17D View Figure 17 ). Metacoxa large, surpassing posterior margin of T3 (Figs 14E View Figure 14 , 17E View Figure 17 ). T1 with longitudinal sulcus on anterior 0.6-0.7, posterior 0.3 with two sublateral carinae sharply defined and delimiting a slightly raised area (Figs 14E-G View Figure 14 , 17E, F View Figure 17 ). T2 transverse, with smoother central area, slightly elevated from coarser lateral areas (Figs 14E, F View Figure 14 , 16E, G View Figure 16 , 17E, F View Figure 17 ). Hypopygium folded medially and with several pleats. Ovipositor sheaths about same length or slightly shorter than metatibia length.

Putative autapomorphies and potentially related genera.

An unusual T1 within Microgastrinae , which has a longitudinal sulcus on the anterior 0.6-0.7 of its length and the posterior 0.3 has two short carinae centrally delimiting a slightly raised area. The propodeum has complete transverse and longitudinal carinae, which is rarely found in Microgastrinae (that trait has also been found in the Old World genera Beyarslania and Neoclarkinella , and in the Neotropical genus Prasmodon , all of which appear distantly related; and also in the more related Neotropical genera Mariapanteles and Pseudapanteles ). Band of rugosity posteromedially on scutellum. Fore wing with very small, slit-shaped areolet. This genus is morphologically similar to Mariapanteles but differs in the posteromedian band of the scutellum being rugose, T1 with two carinae on posterior third, and fore wing with an areolet. Pseudapanteles , which is morphologically related to Mariapanteles , can be separated from Janhalacaste by all those features and also by lacking a transverse carina on propodeum.

Biology.

Hosts include several species of Depressaridae .

Distribution.

The known species are found in the Neotropical region (Costa Rica).

Molecular data.

The three species described below have DNA barcodes available, corresponding to the BINs BOLD:AAK9733, BOLD:AAK0117 and BOLD:ACB2460. Overall, the Janhalacaste BINs are clearly separate from the rest of Microgastrinae (more than 10% base pairs difference from the closest sequence available in BOLD).

Etymology.

The genus name refers to and honors the ecologists Daniel Janzen and Winnie Hallwachs, as well as Area de Conservación Guanacaste (ACG) in northwestern Costa Rica, for the great contributions that both have made to our understanding of Microgastrinae diversity. It is impossible to separate Dan and Winnie from ACG; thus, we are happy and honored to name a new genus of microgastrine wasps after them all. Accordingly, the first part of the genus name is a combination of the first three letters of each researcher’s last name ( “Jan” from Janzen, “Hal” from Hallwachs), while the second part of the genus name includes the last six letters of the word “Guanacaste”. The gender of the genus is neuter.

Species.

We describe below three new species for the genus. They can be separated using the following key.
