Borgmeiermyia paraguayana Sehnal, 1998

Figs 1, 6, 10

Borgmeiermyia paraguayana Sehnal 1998: 350 , Figs 1–5(male description), holotype male (Naturhistorisches Museum Wien), type locality: Paraguay, San Bernardino [ca. 25°16'S, 57°19'W].

Material examined: BRAZIL, State of São Paulo, São Paulo, Ipiranga, 6 males and 1 female, xi.1998, C. [Carlos] Campaner leg. ( MZSP) (one male dissected).

Description of female. Body length: 5.3 mm (n=1), wing length: 3.8 mm (n=1). Differs from the male description ( Sehnal 1998) by its parafacial with silvery yellowish pruinosity below; the antenna yellow and not multifissicorn; the narrow band on the basal portion of tergites 3, 4 and 5 silvery yellowish pruinose. Length of median lateral scutellar seta between 2/3 and 3/4 length of posterior lateral scutellar seta.

Comments: The male was described by Sehnal (1998) with illustrations of habitus and right wing of the holotype, and the terminalia and sternite 5 of a paratype. The male aedeagus is illustrated in more detail here (Figure 1) based on a dissected male from southeastern Brazil. This species differs from B. brasiliana and B. rozeni by the median pair of lateral scutellar setae long, clearly longer than one-half length of posterior lateral scutellar setae and from B. peruana by the cerci curved not so strongly. The cerci of B. paraguayana differ from that of B. brasiliana by the apical portion of this structure broader (subtruncate) in the lateral view and by the median-posterior region no curved. As mentioned above, we found intraspecific variation in the dorsal setulosity of R 4+5 (see comments on the Key to identification).

Puparium. (Figure 10). Length: 4.9 mm (n=4), width: 2.1 mm. Medium-sized, moderately elongate, reddish-brown. Anal spiracular plates shiny black, close to each other, not prominent and clearly above midline of puparium. Each anal spiracular plate with four sinuate respiratory slits somewhat convergent with the median scar.

Host record: The specimens from São Paulo were reared by Carlos Campaner (Museu de Zoologia, São Paulo) from one adult tettigoniid. The host was identified as Phylloptera sp., probably Phylloptera ovalifolia Burmeister, 1839 ( Orthoptera , Tettigoniidae , Phaneropterinae ). This is the first host record known for Borgmeiermyia .

Distribution: BRAZIL (Sao Paulo) rec. n., PARAGUAY (San Bernardino)
