It is also, so far, the third masteriine spider species from the Philippines taxonomically described or included in the scientific database since 1892, after Masteria
caeca and Masteria cavicola, which were discovered in Morong and San Mateo towns, respectively, in Rizal province.
The weights of gizzard, small intestine and
caeca, with and without digesta were determined.
Post-mortem examination of carcasses revealed
caeca were enlarged and distended and ballooning up of caecal pouches with hemorrhagic contents, reddish brown ceacal cores.
Specimens for bacteriological culture consisted of external body surface, gills, heart, liver, stomach content, intestinal content, kidneys, pyloric
caeca and vents were taken during post-mortem parasitological examination.
Pathologic findings such as
caeca ballooning were only observed when chickens were necropsied.
Then, the fish were laparotomized to collect the oesophagus, stomach, pyloric
caeca, mid-gut, rectum and liver.
Tissue sections comprising four of each of the different digestive system sections (oral cavity, oesophagus, stomach,
caeca, intestine, and liver) were instantly fixed in Bouin's solution.
Viscera were weighed and lengths of small intestines and
caeca were measured.
This species has a well-defined stomach, with five to six blind sacs in a pyloric
caeca, and a very short intestine.
Body with linguiform shape, tegument with spines, extending up to the end of intestinal
caeca. Preoral lobe weakly developed.
Anterior projections of the midgut, sometimes described as gastric
caeca, are only found in Euphasmatodea and often obscure the proventricuius.
Caecal bifurcation pre-acetabular closer to oral sucker than to acetabulum, forming caecal shoulders before beginning descent from acetabular level; posteriorly
caeca thick-walled, with short diverticula on median and lateral sides terminating just above excretory bladder (Fig.
