Diagnosis

From Martin 2008
"PPUPARIA (Figs 90-93) – characters of most diagnostic importance are given in bold . As interpreted here, Aleuroctarthrus is defined by the following combination of characters: margin almost smooth, or with very shallow marginal crenulations (Fig. 90); 12 pairs of submarginal setae present (including the nominal caudal pair); 4 pairs of tiny submedian cephalothoracic setae and pair of 8th abdominal setae present ; anterior marginal setae absent; submargin and/or dorsal disc sparsely provided with tiny simple pores of one type only (sometimes appearing loculate and sometimes appearing to have a minute central spine); cephalic pair and 6 abdominal pairs of subdorsal compound pores present, each with an acute axial process (Fig. 92), but these processes often not evident (see discussion, below); all abdominal compound pores very large and subequal in size, much larger than the cephalic pair ; abdominal compound pore pairs located on segments III-VIII (as in Aleurodicus, see Fig. A); two pairs of cicatrices present on thoracic area (scars of third-instar compound pores); with only two large lingular setae (Fig. 91) (sometimes with two very small additional setae visible under 400X magnification); lingular apex excluded beyond vasiform orifice. Ventrally, each leg very large and with an apical claw (Fig. 90); antennae very long, reaching at least to middle legs; underlying abdominal segment VII / VIII boundary (between operculum and fourth abdominal pair of compound pores) is a pair of circular secretory glandular areas (Figs 90, 93), each comprising subcircular cells (often with secreted material somewhat obscuring the structure, and the diaphanous nature of the ventral cuticle often leads to displacement). [2nd-instar with 3 pairs of compound pores, on cephalus, prothorax and last abdominal segment; 3rd-instar with 3 pairs of cicatrices in same positions.]
ADULTS – with eight-segmented antennae; antennae of males not provided with numerous prominent sensoria; abdominal wax plates numbering four in females and three in males , the posterior two pairs in females with stout setae along their anterior edges. Wings clear, unpigmented."
