Control of cercal
position during flight in the cockroach: a mechanism for regulating sensory feedback.
It unquestionably belongs to the calyptrate family Anthomyiidae because of the following combination of characters: (1) head holoptic in male, dichoptic in female; (2) female with a pair of crossed interfrontal setae; (3) lower calypter well developed; (4) tiny hair-like setulae present beneath tip of scutellum; (5) vein A1 extended to wing margin as a weak fold; (6) male surstyli and cerci united by vertical sclerotized connections immediately distal to lateral cercal
apodemes; (7) spiracles VI and VII present in female abdomen.
exploration license located in coastal Alentejo province (Southern Portugal) some 110km due South of Lisbon covers a total area of 455 km[sup.
5th sternite with blunt spines (generally 3) on inner margins more distally placed; acrophallus on distiphallus apparently membranous, and paraphalli arising on distal section closer to base; cercal
plate with longer setae (shorter in coei); surstylus slightly straight in profile (alaba species group and coei) 2 5th sternite with median blunt spine(s) on inner margin medially placed, with another spine apically; acrophallic structure partly sclerotized and placed below extended paraphalli; cercal
plate with shorter setae; surstylus sinuate in profile (longitheca species group) 7 2.
calidus have only eight cercal
sensilla (setae) while those of Hoperius have numerous medial and lateral sensilla.
Lilliput, with its ads for toothpaste and breakfast cercal
, was as culturally and politically unpretentious as an intelligent magazine can be.
We can insulate shaped wire against extreme temperatures with coating materials such as Alcal and Cercal
, a glass/metal compound with an operating range of 368[degree] to 1300[degree] F.
Miller and his colleagues have turned their attention to the cercal
sensory system of the cricket.
plate very small with 2 long setae; clasping cercus thick, with short, somewhat acute anterior apex curved forward (with apical tooth).
plate rectangular in general shape with clear apical notch, two small dark processes apically (Fig.
calidus include: i) absence of secondary cercal
sensilla, ii) spine-like rather than lamellate frontoclypeal sensilla, and iii) differences in the distribution and size of the stemmata.
Furthermore, important differentiating characters are located on the cercal
part of the epandrial complex as well as the hypandrium, surstylus, postgonite and phallus.
