Diagnosis.
As for genus.
Remarks.
Sakai (1961)
described the species from two males in Tosa Bay,
Japan
, but it is not known where the
types
are now kept. They are not in the National Museum of Nature and Science, Tsukuba (formerly National Science Museum,
Tokyo
).
Ng et al. (2017)
discussed the matter of Sakai’s material at length, with extant material in the Smithsonian Institution, Naturmuseum Senckenberg,
Kanagawa
Museum or lost.
Fortunately, the male specimen on hand agrees in all aspects with the description and figures in
Sakai (1961
,
1976
) and we have no doubt of its identity. During a research cruise (LUMIWAN 2008) to southwestern
Philippines
in 2008 jointly organised by the Bureau of Fisheries and Aquatic Resources of the
Philippines
, Philippine National Museum, Musèum national d’Histoire Naturelle (Paris), Lee Kong Chian Natural History Museum, and National
Taiwan
Ocean University, a male specimen of
Neparilia tuberculata
was obtained and photographed fresh (
Fig. 13
). It agrees with the male specimen on hand in all key aspects although its G1 was not photographed. Unfortunately, the specimens from this cruise are not available for study for the time being and we are unable to add this to our material examined. The colour of the fresh specimen, however, is striking, being a bright orange on all the dorsal surfaces with the ventral regions white. This agrees well with the Japanese female figured in
Ikeda (1998: 85)
.
Distribution.
Neparilia tuberculata
is known only from
Japan
(
Sakai, 1961
,
1976
;
Ikeda, 1998
;
Marumura & Kosaka, 2003
) and the
Philippines
(present record).
