Key to known Stempellinella View in CoL View at ENA pupae
The pupae of Stempellinella apicula , S. brevilamellae , S. coronata , S. distincta ,, and S. sublettorum remain unknown.
1. Frontal apotome with coarse granulation and median antepronotal on obvious tubercle ( Figure 20A, B View Figure 20 )................. 2
– If frontal apotome with granulation, median antepronotal not on tubercle.. 4
2. Frontal tubercles long, tubular; points on tergites IV–VI posterolaterally directed ( Figure 32A, B View Figure 32 ); China and Nearctic region...... Stempellinella sp. B
– Frontal tubercles short, conical; points on tergites IV–VI posteriorly directed ( Figure 8A, C View Figure 8 ).................... 3
3. Hook row with more than 31–46 hooks; three lateral taeniae on segment VIII ( Figure 20D View Figure 20 ); South America............ S. lamellata View in CoL
– Hook row with 22–30 hooks; two or three lateral taeniae on segment VIII ( Figure 8C View Figure 8 ); widely distributed........... S. chambiensis
4. Frontal tubercles long, tubular; tergites IV–VI with point patches divided both longitudinally and transversely, giving the appearance of four patches per tergite ( Figure 14C View Figure 14 ).................... 5
– Frontal tubercles less developed, conical; tergites IV–VI with rectangular or p - shaped point patches ( Figure 16C View Figure 16 ).............. 6
5. Posterior points in tergites III–V medially directed ( Figure 14C View Figure 14 ); Holarctic region................... S. edwardsi View in CoL
– Posterior points in tergites III–V straight or posterolaterally directed ( Figure 22C View Figure 22 )................ S. leptocelloides
6. Tergite III with points in small oval patches ( Sasa 1980, p 79, Figure 22B View Figure 22 ); Japan, Canada.................. S. tamaseptima View in CoL
– Tergite III with points in rectangular, large triangular or p -shaped patches ( Figures 16C View Figure 16 , 24C View Figure 24 ).................. 7
7. Thorax without granulation; tergites II–VI with rectangular point patches; 8–14 taeniae in anal fringe ( Figure 24C View Figure 24 ); Europe......... S. reissi View in CoL
– Thorax at least with some granulation; tergite II with triangular point patches, point patches on tergites V–VI not rectangular; more than 13 taeniae in anal fringe ( Figure 10B, C View Figure 10 )................... 8
8. Median antepronotal on tubercle; thorax with extensive granulation and small wrinkles ( Figure 16B View Figure 16 ); Nearctic region.......... S. fimbriata View in CoL
– Median antepronotal not on tubercle; thorax with granulation and wrinkles on anterodorsal part of thorax only ( Figure 10B View Figure 10 )........... 9
9. Point patches on tergite II small, barely reaching anterior to seta D5 ( Figure 6C View Figure 6 ) 10
– Point patches on tergite II large, reaching well anterior to seta D5, often to level of seta D1 ( Figures 10C View Figure 10 , 18C View Figure 18 )............... 11
10. Cephalic tubercles widely conical; prealar tubercle inconspicuous ( Figure 31A, B View Figure 31 ); China................. Stempellinella sp. A
– Cephalic tubercles narrowly conical; prealar tubercle is well-developed mound ( Figure 6A, B View Figure 6 ); Europe............... S. brevis View in CoL
11. Cephalic tubercles low, broad cones; tergite VII with anterior or transverse point patches ( Figure 10A, C View Figure 10 ); Europe............ S. ciliaris
– Cephalic tubercles more narrow, pointing cones; tergite VII without armament or only with anterolateral patches of shagreen ( Figure 26A, C View Figure 26 )...... 12
12. Tergite VII without points or shagreen; pleurae without shagreen ( Figure 3C View Figure 3 ); Nearctic region.................. S. boltoni View in CoL
