Type species
Rudisculptus caudalis gen. et sp. nov.; by present designation and monotypy. Gender: masculine.
Diagnosis (Figs 2–6)
In life, puparia black; without secretion of wax over dorsum, wax secretions are seen around caudal tracheal pore; elevated by lateral submargin; submargin merging with subdorsum by a ridge at dorsolateral angle; submargin hidden in dorsal aspect (Figs 2, 5B). Dorsal surface ornamented with reticulated network of tubercles. Submarginal bands of microtubercles present. Laterally elevated submargin expands and folds in mounted puparia and thus, placing the true margin ventrally. Thoracic tracheal pores indicated as small openings at true margin, and marked as deep loops on dorsal submargin, filled with fine microtubercles. Longitudinal moulting suture reaching margin and transverse moulting sutures reaching subdorsal-submarginal demarcation, cephalothorax separated from the submargin in mounted specimens (Fig. 4G); cephalothoracic and abdominal segment sutures reaching submedian area. Anterior marginal setae absent and posterior marginal setae located ventrally on true margin. Cephalic, first, eighth abdominal and caudal setae present, caudal setae located at ventrolateral margin. Vasiform orifice subcordate; operculum covering little more than half the length of the orifice; lingula exposed, tonguelike, tip may reach beyond the margin of the orifice. Caudal furrow prominent. Geminate pores present. Ventral submargin marked with a narrow groove except caudal fold area.
Etymology
The genus epithet is a summative of two Latin words ‘ rudis ʼ and ‘ sculptus ʼ meaning ‘rough’ and ‘sculpted’ attributing to the dorsal surface of puparium seen in the SEM images (Fig. 5B).
Remarks
Puparia of the new genus differ from those of Aleuropleurocelus and Tetralicia Harrison, 1917 in having a smooth true margin and the presence of first abdominal setae, with thoracic tracheal pores indicated at the margin, prominent caudal furrow, a differentiated cephalothorax in some slide mounts, the submargin is demarcated from the dorsal disc at the anterolateral angle by a shallow ridge, the subventral area is demarcated from the narrow submarginal area by a shallow groove, and the thoracic and caudal tracheal folds are not marked with spinules. In the new genus, the inner wall of the vasiform orifice has digitiform projections, the thoracic tracheal pores are clearly indicated at the margin with an extended loop on the submargin, filled with microtubercles and lacking submarginal wax secreting glands, but in Aleuropleurocelus, the inner wall of the vasiform orifice is smooth, the tracheal pore areas are not modified at the margin and the marginal teeth have wax glands at the base. The new genus also differs from Regiominutus Dubey, 2020 in the puparial shape, size, vasiform orifice structure, and in lacking submarginal papillae and a ventral submarginal groove. A comparison of pupal morphological characters with related genera are presented in Table 1.
