vitrata possessed 3 sensilla basiconica (Bl, B2, B3), 2 sensilla styloconica (S1, S2), and 1 sensillum
chaeticum (C), whereas in P.
adspersus may be considered relatively simple, from an evolutionary point of view, especially when compared to the complex repertoire of up to 6-10 different sensillum
morphotypes described in snapping shrimp (Obermeier and Schmitz, 2004), crayfish (Mellon, 2012), and spiny lobsters (Cate and Derby, 2001).
05 mm, n = 6), with a hair-like sensillum
On ventral surface: successively one, two and one coeloconicum sensillum
on Vt1 (no.
Identification of antennal hygroreceptive sensillum
and other sensilla of firefly, Luciola cruciata.
4x as long as wide, with cross-ridges, a little shorter than clava; pedicel much longer than F1 (the shortest funicle segment); F2, F6, and often F4 the longest funicle segments (F6 sometimes slightly longer than F2 and F4), F3 and F5 slightly shorter (F5 sometimes almost as long as F4); F1-F3 and F5 without longitudinal sensilla, F4 with 1 longitudinal sensillum
, and F6 with 2 such sensilla; clava 2.
While the B event appears to be separate from A1 and A2, this does not preclude the possibility that it could result from the coupling of at least two other events within the peg sensillum
1a); and (b) Blunt trichoidea are hair like, the tip of the sensillum
is slightly blunt and based on their length further classified into a (a-iii) long blunt-tipped sensilla [STr III] 29.
Smaller type of sensillum
present on anterior margin (between sinuses) of cephalic region, abundant in interspaces between larger sensilla.
Infrared radiation strikes a sensillum
and heats a little sphere inside it.
Hair sensillae are the most widespread type of sensillum
on the arthropod exoskeleton.
0 times as long as wide, with 1 small sensory sensillum
(appendage) on apex and 2 campaniform sensilla under half of length of antennomere.
