Austrophyto Lopes, 1989 View in CoL
Austrophyto Lopes, 1989: 826 View in CoL . Type species: Austrophyto cordobensis Lopes, 1989 View in CoL , by original designation. References : Pape (1996: 39, 176) (diagnosis, world catalogue); Mello-Patiu et al. (2014) (key to genera and list of species from Argentina). Autrophyto : Lopes (1989: 826); incorrect original spelling of Austrophyto View in CoL . Lopes (1989) used two original spellings, Austrophyto View in CoL (p. 826) and Autrophyto (p. 826). By subsequent usage ( ICZN Code Article 24.2.4), Pape (1996: 39) acted as First Reviser and selected Austrophyto View in CoL as the correct original spelling.
Generic diagnosis (males). Rows of frontal setae diverging strongly anteriorly at level of pedicel; proclinate orbital setae lacking; one row of parafacial setae near eye, increasing in length and thickness ventrally; genal setae dark; arista with reduced rays restricted to basal half; 0 + 1 acrostichal setae; postalar wall setulose; two pairs of lateral scutellar setae; apical scutellar setae present; 3 katepisternal setae; third costal sector without ventral setae; cell r4+5 open; male mid femur without an apical, posteroventral ctenidium; abdominal T4 with one pair of median marginal setae; T5 with a complete row of marginal setae; ST5 with a deep posterior cleft (V-shaped); arms of ST5 with basal rounded lobes; basal part of ST5 with a median desclerotized area (‘window’). Terminalia: epandrium reddish; syntergosternite 7+8 without a well-differentiated row of marginal setae; surstylus not flattened and curved inwards in posterior view; postgonite with two long setae; phallus short; basi- and distiphallus fused ventrally, and with an incomplete dorsal hinge; distiphallus noticeably broadened; distiphallus with a swollen, desclerotized ventral area proximal to vesica; dorsal surface of paraphallus curved apically; vesica short and weakly sclerotized, with a microserrated margin; harpes well developed, sclerotized and with a roughened surface, projecting from the ventral surface of the distiphallus; juxta scarcely developed, with apico-lateral membranous lobes and a medial sclerotization (= medial juxtal sclerite) between them; acrophallus not exposed; median stylus and lateral styli slender and tubular; lateral styli with microserrations.
Generic monophyly. The monophyly of this genus is tentatively supported by the unique morphology of the male terminalia. The distiphallus is noticeably broadened in both its ventral and dorsal parts. It has a swollen, desclerotized ventral surface proximal to the vesica ( Figs 12 View FIGURES 10 – 13 , 14 View FIGURES 14 – 18 ). Also, the dorsal surface of the paraphallus is curved, producing a distal expansion of the distiphallus. The juxta is not projected ventrally, as a cap-like structure, as occurs in many other genera of Sarcophaginae . Hence, the acrophallus is located within the “bell-shaped” distiphallus and is laterally covered by the strongly developed harpes, with the styli only exposed apically by the widely open tip of the distiphallus ( Figs 7–9 View FIGURES 1 – 9 ). The connection between basi- and distiphallus, fused ventrally and with an incomplete dorsal hinge ( Figs 2 View FIGURES 1 – 9 , 17 View FIGURES 14 – 18 ), is similar to the condition found in Microcerella and Boettcheria Parker, 1914 . The reduced aristal rays ( Figs 28–29 View FIGURES 27 – 34 ) are similar to those found in Microcerella and in a few Boettcheria (e.g., B. mundelli Blanchard, 1939 ). The shape of the surstylus and the poorly developed juxta resemble those of Boettcheria , but the vesica is much less developed in Austrophyto . Additionally, the absence of a well-differentiated row of marginal setae on syntergosternite 7+8 and postgonite with two setae are also possible autapomorphic characters of Austrophyto .
