Revision of the Bengalia spinifemorata species-group (Diptera, Calliphoridae) Author Rognes, Knut text Zootaxa 2011 2835 1 29 journal article 10.5281/zenodo.277348 7f94e40f-9582-4d0c-b1e9-f9f54ffb10f4 1175-5326 277348 4. Bengalia smarti ( Lehrer, 2005 ) , comb. nov. Figs. 35–43 . Maraviola smarti Lehrer, 2005 : 168 , 169 fig. 75. Holotype male (BMNH, examined), by original designation. Type locality: South Africa , KwaZulu-Natal, Mooi River. Note. Rognes (2006: 468) erroneously synonymised M. smarti with M. racovitzai . Bengalia ( Ochromyia ) spinifemorata : Malloch, 1927 : 409 , incl. fig. 12. Misidentifications, not spinifemorata Villeneuve. A specimen from Willow Grange identified by Malloch has been examined. Note. Malloch figures the ST5 flap excavation to be broadly U-shaped. He reports to have seen material from “Willow Grange, Natal , March and April, 1914 ( R. C. Wroughton ); …” which is the type locality of M. smarti , “…; Salisbury, S. Rhodesia ; …”, and “… Entebbe, Uganda , 3.v.1909 ( C. C. Gowdey ).”. A specimen from Willow Grange dated “ 7.iii.1914 ” and collected by R. C. Wroughton is present in BMNH and has been identified and labelled by Malloch as “ Bengalia spinifemorata Vill. ”. It belongs to B. smarti (Lehrer) , cf. list below. Bengalia ( Ochromyia ) spinifemorata : Malloch, 1929 : 119 . Misidentifications, not spinifemorata Villeneuve. Not examined. Note. Malloch here records “Two males and one female, Salisbury, S. Rhodesia , 29.ii.1912 , 10.iii.1927 , and iv.1928 , the last two collected by A. Cuthbertson …”. None of the specimens in BMNH I have seen from “S. Rhodesia ” have dates that correspond to those cited by Malloch. Cuthbertson (1933: 93) explains that the specimens cited by Malloch from Salisbury and collected by Cuthbertson were collected in “dark corners of the Entomological Laboratory.” Ochromyia spinifemorata : Cuthbertson, 1933 : 93 . Misidentification, not spinifemorata Villeneuve. Examined. Note. I have examined two specimens in BMNH collected by Cuthbertson in “S. Rhodesia ”, both belonging to B. smarti . One is a misidentified paratype of M. racovitzai Lehrer from Salisbury, the other is a specimen from Umtali. I take this to signify that all Cuthbertson’s material from “ Southern Rhodesia ” belongs to this species. Cuthbertson also reports on the material from Zimbabwe (as “ Southern Rhodesia ”) mentioned by Malloch (1929) , cf. previous entry. Bengalia spinifemorata : Zumpt: 1956 : 169, fig. 97 (two upper figures of the “hypopygium”, from “ Natal ”). Note. These figures may refer either to B. smarti or to B. racovitzai , because of the strongly sclerotised dentate process. Since B. racovitzai is not known from Natal in South Africa , I assume the figures represent B. smarti , which agrees with the fact that the drawing shows a non-tapering dentate process. I am not able to say with any confidence which species the two figures of the ST5 flap (“apical plates”) below the hypopygium figures belong to. The left figure, with shallow excavation, may be from B. seniorwhitei , and the right one, with deeper excavation, from B. racovitzai or B. smarti , but no sources are given for the material used for the drawings. Bengalia spinifemorata : Zumpt, 1959 : 429 . Not examined. Note. Zumpt lists material from South Africa ( Natal : Tugela Valley, Royal National Park) which probably belongs to this species. Maraviola racovitzai : Lehrer, 2005 : 162 –163. Paratypes from South Africa in MRAC and paratypes from South Africa and Zimbabwe in BMNH, misidentifications, not racovitzai Lehrer. Note. I have examined all these specimens and they are listed below. Bengalia spinifemorata : Kurahashi & Kirk-Spriggs, 2006 : 63 , 17 fig. 2. Misidentifications, not spinifemorata Villeneuve. Not examined. Note. Their fig. 2 shows a U-shaped excavation to the ST5 flap which also has horns projecting well beyond hind edge of the main part of ST5, thus most likely having been prepared from a specimen of B. smarti . Their material is from Namibia . Bengalia racovitzai : Rognes, 2006 : 466 , 468, 469. Misidentification, not racovitzai Lehrer Note. For that paper I examined a specimen from South Africa (Pretoria) in BMNH. It has now been re-examined and reidentified as B. smarti . Diagnosis. Male . Length: 9–12mm (mean 10.4mm, n=7). Frons at vertex / head width ratio: 0.317–0.358 (mean 0.341, n=5). Very similar in almost all characters to B. racovitzai . The ST5 flap has a deep excavation that is rounded, not triangular, in outline, thus broadly U-shaped ( Fig. 40 ) with a broad bottom. The medial edge of the lobes (“horns”) are concave. The lateral lobes of the flap may be even narrower than shown in Fig. 40 , the tip being rounded in cross-section and even slightly flattened from side to side in dried specimens. In the distiphallus the dentate process is not tapering and pointed, but blunt and broadest distally, with a pale apical ventrolateral part as seen in lateral or dorsolateral view ( Figs. 38, 41 ). The expanded and flattened part of the veil process is dentate along margin and on its main surface. Female . Unknown. Biology. Cuthbertson (1933: 93) reports on the behaviour of this species, common “around large nests of Plagiolepis ants, robbing the latter of the larvae and puparia of Camponotus ants which they were carrying … Spiders, partly crushed lepidopterous larvae … and small Pheidole pupae were also observed to attract the attention of spinifemorata , but only when carried by ants. It is remarkable that no notice was taken of the same food when exposed on a place free from ants in the immediate neighbourhood of many Bengalia .” Discussion. Undoubtedly, B. smarti is the most common species in the B. spinifemorata species-group besides B. seniorwhitei . The three paratypes of M. racovitzai from South Africa in MRAC (cf. Lehrer 2005 : 162), two from Johannesburg and one from Pretoria, all carrying Lehrer’s identification labels reading “ Maraviola racovitzai ”, display both key features of Bengalia smarti (Lehrer) : a rounded U-shaped excavation of the ST5 flap (similar to the one shown in Fig. 42 ), and a distally expanded dentate process with a pale ventral area ( Figs. 38, 41 , which have been made from the Pretoria specimen). The same applies to the three other paratypes of M. racovitzai which are in BMNH and which are carrying the same Lehrer identification label, i.e., a specimen from “Transvaal” (Zumpt leg) ( South Africa ), a specimen from “ Natal Ingogo” ( South Africa ) and a specimen from “Salisbury” ( Zimbabwe ). I have reassigned them to B . smarti , labelled them accordingly, and listed them below. Evidently Lehrer has been unsure about the identification of his own species B. racovitzai and B. smarti . Kurahashi & Kirk-Spriggs (2006: 17 fig. 2) figures the ST5 flap of a species they named “ Bengalia spinifemorata ”. The flap projects well beyond posterior edge of the main part of ST5 and the flap is broadly U-shaped, although with a rather shallow excavation. I take this figure to indicate that their material, from Namibia , belongs to B. smarti . FIGURES 35–42 .
