Brontostoma basalis

description: Brontostoma basalis (Stål, 1859)
B. basalis was described as Daraxa basalis, based on a male from Surinam, without mention of the locality from which it had been collected (Stål 1859, 1872). Today, the holotype of this species is deposited in the Museum of Natural History, Humboldt University, Berlin, Germany (Museum für Naturkunde der Humboldt- Universität zu Berlin, ZMHB) and the label is unclear about the locality where it was found (Figs. 1A, 1B). In this same museum, there is another male of B. basalis labeled as a paratype (Figs. 2A, 2B). Since the latter specimen was not mentioned in the original description (Stål 1859) and does not have a label written by C. Stål (unlike the holotype), it should not be considered as a paratype for taxonomical purposes.
Subsequently, Wygodzinsky (1951) furnished a short diagnosis for the female of this species, based on a single specimen from Surinam (Fig. 3). B. basalis has already been recorded from Guyana, Surinam, and Brazil (Stål 1872; Walker 1873; Lethierry & Severin 1896, Haviland 1931; Wygodzinsky 1949, 1951; Maldonado 1990; Dougherty 1995; Gil-Santana 2008). A male recently collected in northern Brazil (Fig. 4) was preferred for studying the male genitalia, since the phallus structures seem to be best observed in fresh specimens.
Male genitalia: pygophore and parameres mildly exposed in situ (Fig. 5). Paramere apices close in resting position (Figs. 5–6). Pygophore sub-heptagonal (Fig. 5). Median portion of posterior process of pygophore short and rounded (Fig. 6). Parameres curved; apices truncated with a single tooth on each in inferior margin (Figs. 7–8). Phallus simple; phallosoma sinuous in anterior margin with lateral margins more sclerotized (Fig. 9); endosoma process united on median portion; sub-hemispherical (Fig. 10); phallosoma support as in Fig. 11; gonopore process caliciform (Fig. 12).
