Brontostoma basalis ( Stål, 1859 )


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. 1 A, 1 B). In this same museum, there is another male of B. basalis   labeled as a paratype (Figs. 2 A, 2 B). 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).
