Shockley, Floyd W. & Alekseev, Vitaly I., 2014, Glesirhanis bercioi, a new genus and species from Baltic amber (Coleoptera: Endomychidae: Leiestinae) with a checklist and nomenclatural notes regarding fossil Endomychidae, Zootaxa 3755 (4), pp. 391-400 : 396

Key to the genera of Leiestinae

The following key to the genera of Leiestinae has been modified from Tomaszewska (2000b) to include the two previously known fossil taxa and the new genus Glesirhanis .

1. Antennomere 9 greatly enlarged relative to 10 & 11.................................. Phymaphoroides Motschulsky

- Antennomere 9 not enlarged or 10 & 11 also enlarged......................................................... 2

2. Prosternal process very narrow and short; procoxae contiguous or almost so....................................... 3

- Prosternal process moderately broad, distinctly separates procoxae.............................................. 5

3. Body glabrous; antennomeres 9 and 10 subequal in length and shape; lateral edges of pronotum widely bordered, crenulate................................................................................... Panaleies Tomaszewska

- Body pubescent; antennomere 9 of club distinctly shorter and narrower than 10; lateral edges of pronotum narrowly bordered, smooth or almost so.................................................................................... 4

4. Pronotal disc with two longitudinal, subparallel grooves medial to the sulci extending from basal margin to about middle of disc; antennomere 5 distinctly longer than 4 or 6............................................ Rhanidea Strohecker

- Pronotal disc without additional longitudinal grooves; antennomeres 4-6 subequal in length........................... 7

5. Wingless; meso- and metaventrites equal in length; elytra with regular rows of micropuncutres....... Panamomus Gorham

- Wings present; mesoventrite distinctly shorter than metaventrite; regular rows of micropunctures visible only on cleared spec- imens............................................................................................... 6

6. Wings well-developed; antennae dissimilar in both sexes (antennal club modified in male); larger species (3.50–4.50 mm length)............................................................................ Phymaphora Newman

- Wings reduced (long but narrow); antennae similar in both sexes; smaller species (2.37–2.60 mm length).................................................................................................... Stethorhanis Blaisdell

7. Lateral sulci weakly impressed; antennomere 3 subequal to 4........................... Palaeoestes Kirejtshuk & Nel

- Lateral sulci strongly impressed; antennomere 3 longer than 4.................................................. 8

8. Basal sulcus strongly impressed; antennomeres 9 and 10 subequal in size and shape..... Glesirhanis Shockley & Alekseev

- Basal sulcus weakly impressed; antennomere 9 distinctly smaller than 10.......................... Leiestes Chevrolat
