25 km
east of Manila. At the back side of Antipolo Church is a large mystical cave known as Inday Nelly Mystical Cave. It is likely that the female
syntype
was collected from this cave.]

Systaria cervina
, new material from Luzon. 4–5 Left male palp (4 ventral, 5 retrolateral); 6 Retrolateral tibial apophysis, retrolateral; 7 Epigyne, ventral; 8 Vulva, dorsal. Scale lines = 0.1 mm.
Diagnosis.
Males of
S. cervina
can be distinguished from those of
S. elberti
(Strand, 1913)
by the sickleshaped RTA provided with a small dorsal incision in lateral view (
Figs 5–6
). Females can be distinguished from those of
S. elberti
by the anterior bursae abruptly narrowing, forming short, posterior stalks (
Fig. 8
) instead of being elongate-oval, and by the much narrower insemination ducts connected between anterior bursae and posterior spermathecae. The male palpal structure of
S. cervina
also closely resembles
S. insulana
(Rainbow, 1902)
but can be recognized by the more elongated RTA which is greatly narrower at base, and by the smaller conductor.
