Ungla pseudomeleoma Tauber 2019
- A new species of Ungla (Neuroptera: Chrysopidae) that exhibits remarkable homoplasy in male secondary sexual characters
- Ungla pseudomeleoma
Diagnosis. Both males and females of U. pseudomeleoma are distinguished from other Ungla species by their elongate scapes with longitudinal red marks on the dorsum and by the distinctive red lines around their antennal fossae (Figs 1 B, 1 D, 1 E, 1 F, 2 A, 2 B, 2 C). Males also are easily recognized by the unique shapes and setal patterns of the scape and basal flagellar segments (Figs 1, 3), the deeply ridged interantennal surface (Figs 1 C, 1 E, 1 F), and the highly ornamented frons (Figs 1, 3, 5). Females of U. pseudomeleoma do not exhibit the extreme male modifications; however, their elongated scapes and the paired ridges between the scapes are distinctive features (Figs 2 A, 2 B).
Etymology. The species name pseudomeleoma recognizes the elaborate Meleoma - like antennal and frontal modifications expressed by this species. It is a noun in apposition with the generic name. Support for generic placement. In addition to the crucial genital characters described below, this species expresses several externally visible features that support its placement in the genus Ungla (c. f., Tauber et al. 2017). For both males and females, the wing venation—especially the insertion of the basal inner gradate on a radial vein and not on the Psm—is more typical of Ungla species than those in most other chrysopine genera, including Meleoma. In addition, males have enlarged abdominal spiracles; T 9 + ect is truncated so that it and the dorsal apodeme do not extend proximally below T 8; T 9 + ect has a deep anal invagination; sternites 8 and 9 are fully fused, and S 8 + 9 is elongate, plate-like, and terminates broadly with distal margin upturned. All of the above features characterize males of Ungla species. Internally, the structure and composition of the male genitalia is typical of all Ungla species: simple gonarcus without gonocornua, with an unarticulated frontal process on the lateral apodeme; mediuncus narrow, elongate, attached to gonarcal bridge via a flexible hinge; gonosaccus with two patches of robust setae on opposing robust plates; and the absence of a tignum, gonapsis, pseudopenis, gonocristae, and parameres. Female genital characters also are consistent with the genus Ungla: spermatheca round, pillbox-shaped, with tall vellum opening directly to the bursa copulatrix via a dorsal slit; spermathecal duct with two to three curves, extending posteriorly, with a distal filamentous section; subgenitale bilobed distally, with simple pocket or lobe below; and the absence of a praegenitale.
Holotype. The holotype, a male, is in the Florida State Collection of Arthropods (FSCA), Gainesville, FL (Figs 1, 3, 5, 6). Its labels read:  “ PERU: Samme, ca. / 40 km NE Trujillo / Prov. La Libertad / 7 ° 59 ’ S, 78 ° 41 ’ W / elev. ca. 1500 m. / 12 – 17 July 1975 / C. Porter, L. Stange ”;  “ HOLOTYPE / Ungla pseudomeleoma / des. C. A. Tauber 2019 ”. The specimen is in good condition; the right labial palpus is partially covered with a white, frothy material.
