Comparative material
Holotype and paratypes of Australopericoma dissimilis Bravo, 2007 ; paratypes of Pericoma caudata Quate, 1955 (as specified below, in the material examined of A. caudata ).
Etymology
The name refers to the state of the type locality.
Diagnosis
This species is mainly characterized by its male terminalia: hypandrium of uniform width throughout its length, with a series of 9 – 16 sparsely distributed short and strong setae on the ventral surface; gonocoxites with stout spine on inner margin; gonostylus with three bristles as long as its length, two of them inserted apically and one basally; lateral margins of aedeagal apodeme slightly divergent.
Description
Adult male. Eye bridge with 3 facet rows, separated by almost 1 facet diameter ( Figure 1A View Figure 1 ). Interocular suture present, without spur ( Figure 1A View Figure 1 ). Frontal scar patch with lower margin bilobed, without median dorsal projection. 5 – 6 larger alveoli (base of postocular bristles) on lateroposterior margin of eye ( Figure 1B View Figure 1 ). Antenna shorter than wing; scape cylindrical, 1.4× length of pedicel; pedicel spherical; 14 flagellomeres present ( Figure 1A, C View Figure 1 ); basal flagellomeres fusiform ( Figure 1D View Figure 1 ); 13th flagellomere reduced, 14th with long apiculus ( Figure 1C View Figure 1 ); 1st flagellomere without ascoids, 2nd to 9th with pair of C-shaped ascoids, shorter than the segment bearing them ( Figure 1D View Figure 1 ). Mouthparts extending beyond basal palpomere, labellum with apicolateral bristles and three short internal spines. Palpus formula = 1:1.3:1.3:2.1, last palpomere striated ( Figure 1A View Figure 1 ). Wing ( Figure 1E View Figure 1 ) typical of the genus with short Sc; medial fork apical to radial fork, radial fork arising basal to apex of CuA 2; R 5 ending at wing tip. Male terminalia: epandrium pilose, rectangular, longer than wide, distal margin concave ( Figure 1F View Figure 1 ); presence of two foramina near proximal margin. Cercus long, 1.1× length of epandrium, with 1 apical clavate tenaculum ( Figure 1F View Figure 1 ); internal surface of cercus with 4 long bristles near base ( Figure 1F View Figure 1 ) and ‘ papilla-like ’ area at base. Epiproct subtriangular microsetose at apex ( Figure 1F View Figure 1 ). Hypandrium of uniform width throughout its length, with dorsal surface less sclerotized than ventral surface; ventral surface projects ventrally to articulate with parameres ( Figures 1G View Figure 1 , 2A View Figure 2 ). Dorsal surface microsetose on posterior margin and ventral surface, with a series of 9 – 16 sparsely distributed short and strong setae ( Figure 2A View Figure 2 ); Gonocoxite pilose, approximately the same length as gonostyle, and with one stout spine on ventral surface ( Figures 1G View Figure 1 , 2A View Figure 2 ). Gonostylus pilose, with one long apical bristle, one long subapical bristle, and one long basal bristle ( Figure 2B View Figure 2 ). Gonostylus with three small setae at base, close to articulation point. Gonocoxal apodeme triangular anteriorly and bilobed posteriorly, with truncate lobes ( Figure 2B View Figure 2 ). Hypoproct with two sclerites, the basal one less sclerotized, Y-shaped, and with a pair of lateral sclerites; apical sclerite with triangular microsetose apex. Aedeagus asymmetric ( Figures 1G View Figure 1 , 2A View Figure 2 ). Aedeagal apodeme almost as long as aedeagus, with lateral margins slightly divergent ( Figure 2A View Figure 2 ). Paramere pairs asymmetrical, one with 2 posterior-pointing arms and a semicircular basal portion articulating with aedeagus; the other long, with acute apex, and articulating basally with the lateroventral projection of the hypandrium.
Measurements (n = 5)
Head width 0.33 mm (0.32 – 0.34), head length 0.31 mm, wing length 1.31 mm (1.27 – 1.35), wing width 0.46 mm (0.43 – 0.49).
Distribution
This species is currently known only from Santa Terezinha – Paraíba State, and Serrinha – Bahia State, two localities in the semiarid region of north-eastern Brazil.
