Larger spiracles, as seen on the mesothorax
and first-abdominal segment of L.
However, statistically significant differences were detected among the 5 populations for mesothorax (length and width), metathorax (length and width) and width of abdomen.
These differences were most significant with respect to the lengths and widths of the mesothorax, metathorax and width of abdomen (Table 3).
mesothorax and metathorax are longer and wider, and abdomen is wider) (Table 3).
Preopercular pores in 2 diverging elongate groups anterior to anal plates, each group extending anteriorly to about mesothorax and with many pores (100+), these gradually becoming sparser anteriorly; each pore probably almost flat (appearing like a small lens) and rather variable in size, each 4-7 pm wide.
Setae: with one pair medially on dorsum of mesothorax and another pair medially on venter of metathorax.
To administer the extract, sexually mature virgin females were anesthetized with nitrogen and 1 male equivalent of extract was injected into the hemocoel as in earlier studies on Diptera, deep to the lateral mesothorax
through a pleuron.
to AbdVII bearing dorsal setiferous sclerites; marginal sclerites of AbdVII and sometimes those on mesothorax
may be joined together.
Ventral coloration: head black with outer margin of buccula yellow; rostral segment I black, II dark orange, and III-IV yellow (apex of IV black); prothorax black with anterior margin yellow, and outer and posterior margin of propleuron shiny orange; mesothorax
black, with posterior margin partially shiny orange; metathorax black; ostiolar peritreme black; coxae, trochanters, and femora shiny orange; tibiae and tarsi yellow; abdominal sterna black with upper margin of pleural margin shiny orange; genital capsule black.
calvatus the pronotum, clavus, corium, prothorax, and mesothorax
are not entirely yellow, and the antenniferous tubercles are yellowish orange.
