Description
Total length (head + trunk) of
holotype
2.51 mm. Specimens pale white with blue pigments on Ant I–IV, slightly on anterior head, intersegmental areas of antennae and legs; lateral of Th II to Abd IV; presence of irregular spots from Abd
III
– IV; Eyepatches black (
Figure 9D
).
Head. Ant I dorsally with 9 mac and 4 basal spiny smooth mic (
Fig 10D
). Posterior labial chaetotaxy series ‘CG’ with 11 ciliate chaetae (

); and 5 ‘p’ mac (
p1–5
) (
Figure 15D
).
Appendages. Trochanteral organ with 16 smooth spine-like chaetae (
Figure 16D
). Collophore anterior side with 4 subapical mac of equal length, and 4 proximal smooth mic; posterior side with 1 apical ciliated mic and 4 subapical smooth chaetae; lateral flap formula 4(s), 4(m), 4(i) smooth chaetae (
Figures 17
F-G). Manubrial plate with 3 chaetae (
Figure 19C
). Mucro with 3 teeth (

Etymology
The epithet honors our entomologist and friend Dr. Neusa Hamada, collector of the specimens.
Remarks
Salina hamadae
sp.n.
resembles
S. serrana
sp.n.
by body and legs with blue spots, Ant I with more than 6 mac, Abd I with 2 central mac, Abd IV with at least 10 central mac, and mucro with 4 teeth. However,
S. hamadae
sp.n.
differs of
S. serrana
sp.n.
in chaetotaxy of the Th II–III with
p1a
and
p1i
mac, respectively (both absent in
S. serrana
sp.n.
), Abd
III
with 3 lateral mac next to
m5
bothriotrichum (
2 in
S. serrana
sp.n.
), and Abd IV devoid of
A3p
and
A5
mac (present in
S. serrana
sp.n.
)
Salina hamadae
sp.n.
also differs by Ant I with 9 mac (
7 in
S. serrana
sp.n.
), trochanteral organ with 16 spine-like chaetae (
13 in
S. serrana
sp.n.
), manubrial plate with 3 chaetae (
2 in
S. serrana
sp.n.
), and collophore with 8 anterior chaetae (4 mac) and 12 chaetae in three rows on lateral flap, while
S. serrana
sp.n.
has 13 anterior chaetae (3 mac) and lateral flap with 20 chaetae in 4 rows. For additional information, refer to
