The genetics of diamond palpus
in Anopheles stephensi.
Median and terminal apophysis of male palpus
strongly sclerotized and acute at apex (Figs.
apically dilated, 3x width of palpal base (Fig.
1], Mx4: length of fourth palpomere of right maxillary palpus
It has a small pair of dorsal antennae and a pair of maxillary palpus
in ventral position, each palpus
shows two sensillae.
dark brown; third segment cylindrical with subapical sensory pit; fifth segment as long as third; palpal ratio 3.
Cardo reduced; stipes prominent; galea finger-like and elongate, approximately half the length of palpomere (MP) 1; palpus
length, excluding palpifer.
These ratios are as follows: A/CP: the sum of the lengths of palpus
, leg I, and leg IV divided by the sum of length of chelicera and propeltidium indicating length of appendages in relation to body size.
0 times longer than broad; palpus
black, about 4/5 length of prementum.
Head and mesosoma mainly black except for the following yellow parts: maxillary palpus
, hypostomal area, labrum, and mandible, except for red brown apex; clypeus, supraclypeal and lower paraocular areas as in Fig.
The conformation of the palpus
in this species (Fig.
The genus Acerentuloides is characterized by 2 pairs of A-setae on the mesonotum and metanotum; 3 setae on the 2nd and 3rd pair of abdominal legs, of which the apical median seta is minute; well developed labial palpus
with terminal tuft of setae and broadened sensillum; maxillary gland with small, smooth, globular vesicle or granulated appendix on the calyx and with several small globules in distal part; some setae modified as short, thickened sensilla (sd5 on head; [beta]1 and [delta]4 on foretarsus; setae P4 on metanotum, M2 on prosternum, and A2 on thoracic sterna; and accessory setae on tergites and sternites I--VI); 6 setae on sternite VIII; anterior position of seta P3 on abdominal tergites II--VI; developed striate band with clearly visible parallel-sided striae.
