Key to the puparia of Aleuroplatus species of India

* Data from original descriptions in Peal (1903) and Quaintance and Baker (1917).

A. translucidus Quaintance and Baker (1917) was reported from Pakistan but not from India, and is not included in this key.

1.

A. spina (Singh)

-. Submargin/subdorsum with fewer setae, if present, usually not discernable, none reaching well beyond margin; vasiform orifice may be triangular but if so, then posteriorly closed; tip of lingula not D-shaped, if visible......................... 2

2. Puparium translucent white, mostly tinged with yellow; two yellow pigmented spots usually present on abdominal segments I and II; sides of thorax bounded by three lobed lines........................................ A. quaintancei (Peal) *

-. Puparium pale yellow or black, not translucent white; yellow pigmented spots absent on abdominal segments I and II; sides of thorax not bounded by three lobed lines................................................................... 3

3. Puparium almost circular and black; not constricted at thoracic tracheal comb area; vasiform orifice obovate; lingula V-shaped, tip lightly reaching beyond vasiform orifice.................................................... A. hoyae (Peal) *

-. Puparium not circular, but rather elliptical, slightly or much constricted at thoracic tracheal comb area, pale or black; vasiform orifice subcordate, subrectangular or subcircular; lingula not V-shaped.......................................... 4

4. Puparium elliptical, slightly constricted at thoracic tracheal comb area; vasiform orifice wider than long; caudal tracheal fold forming an urn-shaped structure........................................... A. ficusrugosae Quaintance & Baker *

-. Puparium suboval, much constricted at thoracic tracheal pore area; caudal tracheal fold not forming an urn-shaped structure 5

5. Puparium pale, never dark black or black; inner posterior and lateral margins of vasiform orifice exposed and with irregular maculae ( Fig. 18 ); cephalic median area usually with a median keel ( Fig. 16 ).......................... A. alcocki (Peal)

-. Puparium dark black or black, never white; inner posterior and lateral margins of vasiform orifice not exposed, filled by operculum and with fine granular structure ( Fig. 30 ) but not with prominent maculae.................................. 6

6. Eye spots present on cephalic region ( Figs 13 , 36 )........................................................... 7

-. Eye spots absent on cephalic region........................................................................ 9

7. Vasiform orifice subrectangular ( Fig. 14 ); posterior and lateral area of vasiform orifice with many irregular tubercles ( Figs 14 , 38 ); a pair of oblique furrows absent on submedian area of abdomen................ mysorensis David & Subramaniam

-. Vasiform orifice subcircular or subcordate; posterior and lateral area of vasiform orifice without many irregular tubercles ( Figs 26 , 30, 34 ); a pair of oblique furrows present on submedian area of abdomen ( Figs 31, 32 )........................... 8

8. Submedian area of ventral surface not granulated, vasiform orifice circular ( Fig. 30 ), inner margin with fine granules ( Fig. 30 )................................................................... A. keralica P. M. M. David & B. V. David

-. Submedian area of ventral surface granulated ( Fig. 32 ), vasiform orifice nearly subcordate, posteriorly narrow ( Fig. 34 ), inner margin without granules............................................ A. lepidoformis P. M. M. David & B. V. David

9. Thoracic and caudal tracheal comb each with a single tooth invaginated within the margin/submargin ( Figs 8, 9 , 20, 21 )................................................................................ A. incisus Quaintance & Baker

-. Thoracic and caudal tracheal comb each with variable number of teeth, number and length of teeth varies but never invaginated within the margin/submargin ( Fig. 4 ).................................................................... 10

10. Median area of the abdominal segments with only one pairs of pores and porettes; submarginal/subdorsal tubercles less elevated................................................................... A. pectiniferus Quaintance & Baker

-. Median area of the abdominal segments I–IV with three pores and associated porettes ( Figs 6 , 24 ); submarginal/subdorsal tubercles more elevated ( Figs 5 , 27 )........................................... A. cinnamomi Jesudasan & David
