The arrow points to a single T2 chaetic
sensillum magnified in D.
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).
On ventral surface: successively one, two and one coeloconicum
sensillum on Vt1 (no.
Near to the labial tip, subapically, the elongated plate
sensillum was present in representatives of the outgroup (K27); however, it was absent in the Nepomorpha.
Identification of antennal hygroreceptive
sensillum and other sensilla of firefly, Luciola cruciata.
12) with scape about 2.9x as long as wide; funicle (excluding 3 anelli) 4-segmented, F1, F3 and F4 subequal in length, F2 slightly longer; clava 3-segmented, apical segment with a spicula; funicle and claval segments with long hairs and each with at least 2 hairlike longitudinal sensilla (except only 1 such
sensillum on F1).
A high quality, archived recording from a peg
sensillum of Smeringurus mesaensis Stahnke 1957 (Scorpiones: Vaejovidae; formerly Paruroctonus mesaensis) and a new recording from a peg
sensillum of Paruroctonus utahensis Williams 1968 (Scorpiones: Vaejovidae), collected near Kermit, Texas, USA (31[degrees] 57' 46.44" N, 102[degrees] 58' 53.59"W) formed the data set for this paper.
There was no great variation in the width of sensilla, where as
sensillum with a pore or opening to the exterior were measured and classified based on their diameter.
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.
