Tabanipriscus Grimaldi 2016, new genus
No full textTabanipriscus, new genus DIAGNOSIS: Wing broad in middle (W/L = 0.41), significantly tapered apicad; anterior edge not straight, slightly convex; basicosta deeply incised, base of C thick; fork of R 4+5 long, base diverging near level of cell d apex (vs. significantly distad); face with pair of small, rugose callosities; antenna with at least 7 (probably 8) free flagellomeres, tapered apicad; cerci 2-segmented. TYPE SPECIES: Tabanipriscus transitivus, new species. ETYMOLOGY: Taken from the root and type genus name for Tabanidae (Tabanus), and priscus (Latin, “first”), in reference to the plesiomorphic nature of this genus. The gender of the name is masculine. COMMENTS: This is not a species of Tabanidae as currently defined for modern and Tertiary species. It is possible that Tabanipriscus is actually a stem group to Athericidae + Tabanidae. Features of the fossil that are plesiomorphic for Tabanidae include: anterior edge of wing not straight, slightly convex; preserved portion of R 4 only very slightly sinuous; R 4 -R 5 fork not widely divergent (though still apparently encompassing tip of wing), fork longer than in any living Tabanidae, 2 cercomeres. Placement in/near Tabanidae is based on the deeply incised basicosta, very thick base of C, head shape, a pair of facial callosities, mouthpart structure; the broad, dorsoventrally flattened abdomen, and the lack of a peg/knob on the anterior surface of the hind coxa (which all tabanids lack, but which athericids, some pelecorhynchids, and Oreoleptis possess). Pleural metathoracic area of the unique specimen is unfortunately not visible.Published as part of Grimaldi, David A., 2016, Diverse Orthorrhaphan Flies (Insecta: Diptera: Brachycera) In Amber From The Cretaceous Of Myanmar: Brachycera In Cretaceous Amber, Part Vii David A.

ETYMOLOGY: From the Latin castaneus, for the color of chestnuts, in reference to the color of the scutum and scutellum.Published as part of Grimaldi, David A., 2009, The Asteioinea of Fiji (Insecta: Diptera: Periscelididae, Asteiidae, Xenasteiidae), pp. 1-60 in American Museum Novitates 3671 on page 5, DOI: 10.1206/685.1, http://zenodo.org/record/535802
Chandleromyia Grimaldi 2018, new genus
No full textChandleromyia, new genus DIAGNOSIS: (male only). Eyes extensively holoptic; gena bare, occiput with very fine, scattered short setae; clypeus a broad triangle; palp minute; arista bare; acrostichals entirely absent, only 1 pair of (short, prescutellar) dorsocentrals; 1 short pair of scutellars; 4–5 notopleurals. Wing entirely covered with dense microtrichia; M not forked (M 2 lost), dm-cu close to wing margin; CuP slightly curved. Tibiae and tarsi with bifid scales. Metatarsomeres 1–4 flattened, expanded; tarsomere 2 shortest, with blunt spine; tarsomere 3 with clavate seta. Abdomen short, broad; male tergite 7 narrow, tubular. TYPE SPECIES: C. anomala, n. sp. ETYMOLOGY: For Peter J. Chandler, in recognition of his work on global Platypezidae, and on Diptera in general. The genus name is feminine. COMMENTS: This genus is extremely similar phenetically, and apparently close phylogenetically, to Lindneromyia neomedialis, n. sp., in Dominican amber, described below. This is based on the squared oral margin, minute palps; face, gena, arista bare; complete lack of acrostichals, one (short, prescutellar) pair of dorsocentral setae; one short pair of scutellars; no supraalars, one short postalar; loss of vein M 2; r-m crossvein near level of cell Sc apex; and thick, stiff, spinelike setae on posterior margin of tergite 6 lacking. Chandleromyia differs from L. neomedialis based on the setose occiput (completely bare in Lindneromyia); 4–5 notopleurals (vs. 2); wing membrane entirely with dense microtrichia (vs. partially covered with minute, faint ones); cell dm long, with dm-cu close to wing margin (vs. cell short, vein near middle of wing); vein M 1 deflexed (vs. almost straight); vein CuP curved (vs. straight); spine and clavate seta on metarsomeres 2 and 3, respectively (vs. without); male tergite 7 narrow, tubular (vs. short, much broader than long, inserted into emargination of tergite 6). Though separated by approximately 80 million years, the two flies appear closely related. There is no question about the provenance of the two specimens; AMNH DR14-35 was acquired in the 1990s in the Dominican Republic by me; AMNH Bu-KL30-27 was acquired from Myanmar. With a derived platypezine in the mid-Cretaceous, this greatly extends the age of crown-group Platypezidae (fig. 27).Published as part of Grimaldi, David A., 2018, Basal Cyclorrhapha In Amber From The Cretaceous And Tertiary (Insecta: Diptera), And Their Relationships: Brachycera In Cretaceous Amber Part Ix David A.

Lebanopeza Grimaldi 2018, new genus
No full textLebanopeza, new genus DIAGNOSIS: (male only). Eyes holoptic, dorsal facets larger; small prescutellum present; acrostichals in short uniserial row; wing with microtrichia over entire surface; C ends at apex of R 4+5 (vs. M 1); crossvein dm-cu (cell dm) absent, CuP curved; M entirely spectral, branches of M 1 -M 2 fork virtually symmetrical; dark bifid scales lacking on legs; metatarsomeres not expanded; male terminalia lateroflexed to right. Except for the lack of crossvein dm-cu and the faint M vein, all these features appear plesiomorphic for the Platypezidae. TYPE SPECIES: L. azari, new species. ETYMOLOGY: From Lebanon, the country of origin, and - peza (foot), a common suffix for generic names in the Platypezidae. COMMENTS: Lebanopeza appears to be an extinct stem group to Microsania + Melanderomyia (fig. 27). It lacks at least four features that define these two extant genera (chars. 3, 16, 17, 18; table 2), but shares with them the loss of crossvein dm-cu (cell dm), a distinctly shortened Sc vein and somewhat shortened R 1, and reduction in the medial veins. In Melanderomyia M 2 is lost; in Microsania the base of M 1 is lost; in Lebanopeza the entire stem and fork of M 1 -M 2 is extremely faint and unsclerotized. The wing of Lebanopeza is similar to Mauritulus sospes Mostovski, preserved as a compression (along with portions of the body) in shale from the Early Cretaceous of Eurasia (Mostovski, 1995a). Both genera have a slender wing; membrane densely covered with microtrichia; R 1 straight, relatively short; C definitely (Lebanopeza) or apparently (Mauritulus) ending at the apex of R 4+5; M 1 -M 2 fork nearly symmetrical; and crossvein dm-cu (cell dm) absent. Lebanopeza differs from Mauritulus by having a shorter Sc cell (0.3× wing length, vs. 0.45×), cell cup with apical stem of CuP+A 1 (in Mauritulus these veins join virtually at the wing margin), and in having no metatarsomeres expanded (in Mauritulus the basitarsomere is slightly expanded).Published as part of Grimaldi, David A., 2018, Basal Cyclorrhapha In Amber From The Cretaceous And Tertiary (Insecta: Diptera), And Their Relationships: Brachycera In Cretaceous Amber Part Ix David A.
