Key to adult females of Termitaphididae

The following key is updated and modified from the one provided by Usinger (1942).

1. Body egg-shaped, surrounded by a strongly incurved and upcurved, dorsolateral, segmentally divided lamina, the edges of which are further divided into distinct, often quite distantly separated lobules, each with a long, fine almost smooth flagellum [ Colombia; host: Amitermes foreli Wasmann ( Termitidae : Termitinae )] ........................ Termitaphis circumvallata Wasmann

– Entire body strongly flattened above and below and surrounded by a flat, lateral, segmentally divided lamina, the margin of which is crenulate, forming short, non-separated lobules, each provided with a short, circular, clavate, or lanceolate flabellum with serrate edges [Tropicopolitan; Genus Termitaradus Myers ; hosts, where known: Rhinotermitidae ] ........................................... 2

2. Dorsal integument imbricate and granular, with scattered globular nodulelike setae; without raised pattern of carinae ................................................ 3

– Dorsal integument imbricate with network of raised, thick carinae forming distinctive network, such carinae not extending onto laminae (Fig. 1) [Dominican amber; host: unknown] ...................................... T. mitnicki sp. n.

3. Flabella short and rounded, at most scarcely more than twice as long as broad ......................................................................................................... 4

– Flabella elongate, much more than twice as long as broad.......................... 8

4. Eighth abdominal lobes each with two or three lobules; anterior abdominal segments with 7–10 lobules on each side; size small (2–3.5 mm in length) ......... 5

– Eighth abdominal lobes each with four lobules; anterior abdominal segments with at least 12 lobules on each side; size large, over 7 mm in total length [Mexican amber; host: unknown] .................... T. protera Poinar & Doyen

5. Eighth abdominal lobes each with two lobules; anterior abdominal segments normally with seven or more lobules on each side ...................................... 6

– Eighth abdominal lobes each with three lobules on each side ..................... 7

6. Flabella rounded; anterior abdominal segments with not more than seven lobules on each side [ México; host: Heterotermes tenuis (Hagen) (Heterotermitinae) ].................................................................. T. mexicana (Silvestri)

– Flabella short, clavate; anterior abdominal segments with eight or more lobules on each side [ India; host: Coptotermes heimi (Wasmann) (Coptotermitinae) ] ..................................................................... T. annandalei (Silvestri)

7. Flabella of second cephalic lobe half the size of other head and body flabella, but projecting conspicuously, ovate in form [ Guyana; hosts: Heterotermes crinitus (Emerson) & H. tenuis (Hagen) (Heterotermitinae) ] ....................... ................................................................................ T. guianae (Morrison)

– Flabella of second cephalic lobe much smaller, minute, scarcely surpassing margins, perfectly circular in form [ Jamaica; host: Heterotermes convexinotatus (Snyder) (Heterotermitinae) ] ................................ T. jamaicensis Myers

8. Eighth abdominal lobes each with two or three lobules.............................. 9

– Eighth abdominal lobes each with four lobules [Dominican amber; putative host: Mastotermes electrodominicana Krishna & Grimaldi (Mastotermitidae) ].......................................... T. avitinquilinus Grimaldi & Engel

9. Eighth abdominal lobes each with two lobules......................................... 10

– Eighth abdominal lobes each with three lobules....................................... 11

10. Flabella long, narrow, clavate, with straight sides and squarely truncate tips, not echinate; anterior abdominal lobes each with eight or more lobules [ Australia; host: Coptotermes acinaciformis (Froggatt) (Coptotermitinae) ] ............ .......................................................................... T. australiensis (Mjöberg)

– Flabella subcylindrical, rounded at apices or at most very obtusely pointed, echinate; anterior abdominal lobes each with seven lobules [Africa; host: Schedorhinotermes putorius (Sjöstedt) (Heterotermitinae) ] ........................... ................................................................................. T. subafra (Silvestri)

11. Flabella lanceolate, very acute at apices [ Panamá; hosts: Heterotermes tenuis (Hagen) & H. convexinotatus (Snyder) (Heterotermitinae) ] ........................ ................................................................................ T. panamensis Myers

– Flabella moderately clavate, rounded at apices [ Trinidad & Tobago; host: Heterotermes tenuis (Hagen) (Heterotermitinae) ]...... T. trinidadensis (Morrison)
