Botanophila mayorgae View in CoL sp. nov.

( Figs 2 View FIGURE 2 , 5 View FIGURE 5 )

Diagnosis: Interfrontal setae similar to frontal setae. Proclinate orbital setae developed. Cerci in posterior view, enlarged and long, twice longer than its width, shorter than surstyli, apically furcated, with an acute point on each side and among them a median apical process. Surstyli in lateral view slightly curved towards cerci. Surstyli in lateral view slightly curved in the opposite direction to cerci, apex not enlarged.

Description: Male. Body length: 5.8 mm. Wing length: 6.0 mm.

Color: General coloration light brown with gray pruinosity. Frontal vitta dark brown with ochre yellow on the lower third, fronto-orbital plate, parafacial, and gena with gray pruinosity. Antennae and palpus dark brown. Mesonotum with three inconspicuous brown stripes. Calypter and halter white-yellowish. Legs light brown with gray pruinosity, tibiae concolorous with femora. Wing slightly brownish, with yellowish veins. Abdomen with a poorly delimited dorsal median stripe.

Head ( Fig. 2A View FIGURE 2 ): Dichoptic; parafacial at mid-height only half as wide as postpedicel; gena almost twice wider than pedicel; frons broad, frontal vitta with about 3/5 of frontal width, with strong inner and outer vertical setae (the inner vertical setae 1/5 longer than the outer), a pair of interfrontal setae, 2 proclinate orbital setae and 2 frontal setae plus 3 frontal setulae. Antenna long; arista pubescence, hairs with similar length to the greatest basal diameter of arista.

Thorax ( Fig. 2B, C View FIGURE 2 ): 3 presutural acrostichal setae, very short; postsutural setae not visible due to the pin. Prealar seta similar to posterior notopleural seta. Anepisternum with a long anterior setula, below anterior notopleural seta. Katepisternal setae 1+2. Dorsocentral setae 2+3. Upper calypter with long marginal setulae, with almost the same length of calypter width. Lower calypter reduced to almost linear, narrow fold. Apical and basal scutellar setae long, twice longer than scutellum length.

Wing: Vein C ventrally bare, with some setulae apically after subcostal vein; section between basal and costal breaks with slightly enlarged av spinules. Cross-vein dm-cu straight.

Legs: Fore tibia with a submedian ad seta and a median pv seta, apically only with a pv seta and a longer d seta. Mid femur with ad and av rows of setae and a long pv row of setae, long preapical setae on p and pd; mid tibia with 1 submedian ad, 2 pd (supramedian and submedian) and 2 pv setae (median and submedian), preapical setae on p and pd absent, apical long setae on av, pv and v, in addition to shorter setae on remaining surfaces. Hind femur with a row of robust ad and av setae, twice longer than femur width; hind tibia with 2 av (median and submedian), 4 ad, 3 pd, and 1 pv seta (supra median), apically with long and robust seta on ad, av, and d. Pulvillus enlarged, longer than width of tarsomere.

Abdomen ( Fig. 2B, C View FIGURE 2 ): Tergite 6 bare. Sternite 1 setulose, with long setulae marginally. Sternite 5 ( Fig. 5A View FIGURE 5 ) processes with long lateral setae on the outer margin and shorter setae on the inner margin.

Terminalia ( Fig. 5 View FIGURE 5 ): Cerci in posterior view, enlarged and long, twice longer than its width, shorter than the surstyli, apically furcated, with an acute point on each side and among them a median apical process ( Fig. 5B View FIGURE 5 ). Surstyli long, narrow, and slightly curved. Hypopygium ( Figs 5D, E View FIGURE 5 ) of the Botanophila - type, i.e. pregonite reduced and shallow, firmly connected to the central plate of hypandrium, and with 2 long setae; postgonite twice longer than pregonite; epiphallus and distiphallus reduced; distiphallus largely membranous except for a pair of anterobasal sclerotized rods ( Fig. 5D, E View FIGURE 5 ); phallapodema long and apically enlarged in dorsal ( Fig. 5E View FIGURE 5 ) and lateral ( Fig. 5D View FIGURE 5 ) view.

Female: Unknown.

Morphological variation: (n=2). Body length: 5.4–5.8 mm. Wing length: 5.5–6.0 mm.

Etymology: Name in apposition. This species is named in honor of María Cristina Mayorga Martínez , entomologist of the Instituto de Biología, UNAM.

Material examined: Holotype. Male. “ MEXICO Tlaxcala \ La Malinche \ alt. 3400m 16. VI.84 \ E. Ramírez ” [19.238494; -98.031407] ( CNIN) GoogleMaps . Paratype. 1 male, Mexico, Parque Nacional Zoquiapan , 3200 m, 31.vii.1980 [19.086448; -98.645898] ( CNIN) GoogleMaps .

Distribution: Mexico (State of Mexico and Tlaxcala).

Remarks: The tentative assignment of this new species to brunneilinea- group is based on the shape of cerci: large dorsally with distal margin nearly reaching the apex of surstyli and in the distal quarter narrowly separated and forming two points. This new species is easily distinguished from other known Botanophila species by the male head with dichoptic eyes, interfrontal setae and proclinate orbital setae developed. It is very similar to Botanophila zaldivari sp. nov., but can be differentiated from it by the dark brown tibiae, shorter cerci and the slightly curved surstyli.
