Description

Male (Fig. 2). Length: 3 mm. Head (Fig. 2b): postpedicel orange basally, directly adjacent to pedicel; arista orange on apical half; ocellar setae well-developed, proclinate and divergent, arising behind anterior ocellus; fronto-orbital plate with two regular rows of short setulae outside of frontal setae; frontal setae appearing as continuous with parafacial setulae; two pairs of proclinate orbital setae, one pair of reclinate upper orbital setae. Thorax (Fig. 2a, c): three postsutural supra-alar setae, middle seta twice as long as outer two; two postsutural intra-alar setae; four postsutural dorsocentral setae; scutellum with one pair of basal scutellar setae, two pairs of lateral scutellars and one pair of weaker divergent apical scutellar setae; scutellum bearing one pair of weak but evident discal setae slightly wider than apical scutellars. Legs (Fig. 2c): entirely glabrous black, as in generic description. Wing (Fig. 2a): hyaline, very slightly darkening basally; basicosta dark brownr; wing vein R4+5 bearing 5-6 setulae extending 0.75 × distance from node to crossvein r-m on dorsal surface; ventral surface bearing at most 0-2 setulae; calypters pale white translucent. Abdomen (Fig. 2a, c): ground color of abdomen glabrous maroon or reddish-black; very slight silver tomentum only visible when observed under different angles of light, appearing as a silver sheen on dorsal surface of tergites; complete row of marginal setae present on both T4 and T5; median discal setae absent on all tergites except row on T5.

Female: unknown at this time, assumed to be similar to male as is the case with the type species.

Diagnosis

Trismegistomya jimoharai sp. n. is easily differentiated from its only congener, the type species T. pumilis Reinhard, by the following combination of traits: basal portion of postpedicel distinctly orange; arista orange apically; and four postsutural dorsocentral setae.

Etymology

Trismegistomya jimoharai sp. n. is named in honor of Dr. James O’Hara of Ottawa, Canada in recognition of his many years of support to the curation, taxonomy and administrative logistics of the on-going effort to inventory the caterpillar-attacking species of Tachinidae of ACG and secure the residence of their voucher specimens in the Canadian National Collection.

Distribution

Costa Rica, ACG, Prov. Guanacaste, coastal margin dry forest, 10 m elevation.

Ecology

T. jimoharai has been reared two times, from only four larvae of Melipotis januaris ( Guenée, 1852) ( Lepidoptera : Erebidae ) reared by the inventory to date and collected while feeding on Pithecellobium oblongum Benth. ( Fabaceae ) in ACG dry forest. It should be noted that Trismegistomya has not been noted out of the other 808 rearings of Melipotis spp. reared by the inventory.
