Total length (head + trunk) of holotype 1.75 mm. Specimens pale white with dark blue pigments on Ant I–IV, strongly on anterior head, intersegmental areas of antennae and Th II to Abd III; irregular blue spots on the side of the head, Th II and Abd II–V; inner side of legs with a distal spot on femora and two spots in tibiotarsi (one basal and one subapical). Eyepatches black ( Figure 9A View Fig ).

Head. Ant I dorsally with 4 mac and 5 basal spiny smooth mic ( Fig 10A View Fig ). Posterior labial chaetotaxy series ‘CG’ with 7 ciliate chaetae (CG1-3, CG5, CG6p–7e) and 2 serrated mic (CG4, CG6); series ‘PLM’ with 2 ciliate chaetae (PLM1–2); series ‘PLE’ with 2 ciliate chaetae (PLE1–2); lateral side with about 29 ciliate chaetae ( Fig 11A View Fig ).

Dorsal chaetotaxy. Th II with 1 ‘p’ mac (p3). Th III with 3 ‘p’ mac (p2–3, p5) ( Figure 12A View Fig ). Abd I with 1–2 ‘m’ mac (m3, m4), m3 rarely absent ( Figure 13A View Fig ). Abd III with 1 ‘a’ mac (a7), 2 ‘m’ mac (am6, pm6), and 3 ‘p’ mac (p6, p7i and one unnamed) ( Figure 14A View Fig ). Abd IV with 2 ‘A’ mac (A1, A6); 1 ‘Ae’ mac (Ae1); 3 ‘B’ mac (B3–5); 1 ‘Be’ mac (Be1); 1 ‘C’ mac (C1); 4 ‘E’ mac (E1-4); 4 ‘F’ mac (F1–F3p); 2 ‘Fe’ mac (Fe1–3); posterior side with 3 sens type IV (ps and two unnamed) ( Figure 14D View Fig ). Abd V with 2 ‘a’ mac (a3, a5); 3 ‘m’ mac (m2–3, m5); and 5 ‘p’ mac (p0-4) ( Figure 15A View Fig ).

Appendages. Trochanteral organ with 12 smooth spine-like chaetae ( Fig 16A View Fig ). Collophore anterior side with 2 subapical mac of unequal length and 1 median mes, and 7 proximal smooth mic; posterior side with 1 apical and 2 subapical smooth chaetae; lateral flap formula 4(s), 2(m), 5(i) smooth chaetae, 2 inferior larger ( Figures 17 View Fig A-B). Manubrial plate with 3 chaetae ( Figure 19C View Fig ). Mucro with 3–4 teeth (d1, ap, v1-2), v2 teeth present or absent ( Figure 19D View Fig ).


The name “brasiliana” refers to the wide distribution of this species in Brazil.


Salina brasiliana sp.n. resembles the different forms of S. celebensis Schäffer, 1898 , widely recorded in South Asia, by body color with dark blue spots on trunk and legs, dorsal chaetotaxy of Th II–Abd I with 1, 2, 2 central mac, respectively, Abd II with 2, 1 mac, prelabral and labral chaetotaxy, maxillary outer lobe and sublobal plate, basolateral and basomedian labial fields, unguiculus truncate, and mucro with 3 teeth (see Schäffer 1898; Handschin 1925; Denis 1936; Yosii 1959; Yoshii 1981, 1983; Yoshii & Suhardjono 1989; Yoshii & Greenslade 1993). However, S. brasiliana sp.n. differs from S. celebensis from Celebes (type locality), by spots on trunk and legs (only one lateral strip on Th II of S. celebensis ), and mucro generally with v2 teeth present (absent in S. celebensis ), being that this last characteristic is not present in differents forms of S. celebensis from Asia (see Table 2 View Table 2 ). Salina brasiliana sp.n. also differs from specimens

of S. celebensis from Bukit Timah, Singapore (sensu Yosii 1959) by unguis with inner median tooth (absent in S. celebensis ), trochanteral organ with 12 smooth spine-like chaetae (18 in S. celebensis ), Abd III with 6 lateral mac (1 in S. celebensis ), and Abd IV with 8 central mac (10 in S. celebensis ). Specimens of S. celebensis from Sabah and Malaysia has Abd III with 3 lateral mac and Abd IV with 10 central mac, as well as about the color pattern with or without spots on trunk, this may be considered a variation expressed in lineages close related to S. celebensis ( Yoshii 1981, 1983). The new species still differs from specimens of S. celebensis from India (sensu Denis 1936; Mitra 1973), by Th II–Abd I with 1, 2, 2 central mac, respectively (7, 5, 2 in S. celebensis ), besides of extra mucronal tooth (v2), absent in S. celebensis .

Salina brasiliana sp.n. also resembles other Neotropical species, S. panamae Jacquemart, 1982 , in general morphology, including the reduction of central mac on Th II–III and Abd IV with 8 central mac (see Jacquemart 1982; Soto-Adames 2010). However, S. brasiliana sp.n. differs from this species by the color pattern with irregular spots (reduced in S. panamae ), Th III without p1 mac (present in S. panamae ), and Abd III with 3 lateral mac (am6, pm6, p6) next to m5 bothriotrichum (2 in S. panamae ).

Thus, the formula of Th II–Abd I (1, 2, 2 central mac) is not exclusive of S. brasiliana sp.n. and S. celebensis , since it is also present in S. greenslade Yoshii & Suhardjono, 1989 , S. bicolor sp.n. and S. serrana sp.n. (see remarks of these new species). For this reason, identification based on formula Th II–Abd I, as well as color pattern, may not be accurate ( Soto-Adames 2010). Thus, the records of S. celebensis in Brazil and Argentina ( Cassagnau 1963; Soto-Adames 2010), probably refers to S. brasiliana sp.n.

The populations of S. brasiliana sp.n. have similar variations independently of the region from Brazil. Specimens in general have two central mac on Abd I ( Figure 13A View Fig ), but frequently m3 mac is absent on at least one body side in specimens from North Brazil (Acre, Amapá, Amazonas, Roraima and Rondônia States). In this same region the specimens often have 3 or 4 mucronal teeth, in both or only in a dens, whereas in the specimens from South Brazil (Paraná and Santa Catarina states) has greater tendency of 3 mucronal teeth (v2 absent). In Abd IV rarely Ae3 is mac/mes, at least in specimens from Amazonas and Acre states, but this may be related to the development stage.
