Key to the genera of the family Gryllotalpidae View in CoL based on genital characters

(Not including Triamescaptor and Gryllotalpella )

1. Parameres of the ectophallus fused in a single paramere, just as the transversal sclerite of the epiphallus is (fig. 19)................................................................................................... Indioscaptor

- Parameres of the ectophallus and transversal sclerites of the epiphallus non-fused (figs. 15–18, 20–21).................. 2

2. Antero-apical process (aap) of ectophallus present (figs. 9–10)................................................. 3

- Antero-apical process (aap) of ectophallus absent (figs.11–14).................................................. 4

3. Apical sclerite of the epiphallus pronounced, three to four times longer than it is wide, antero-apical process of ectophallus sclerotized (fig. 21)...................................................................... .. Scapteriscus s. l.

- Apical sclerite of the epiphallus only slightly pronounced, 1.5 longer than it is wide, antero-apical process of ectophallus

mostly membrane-like (figs. 20).................... Scapteriscus s. s. (included S. oxydactylus and possibly S. headsi ). 4. Transversal sclerites of the epiphallus pedunculate, “T” or “L”-shaped; epiphallus s. s. tubular, longer than it is wide. Ectophallus: Latero-basal sclerite absent, internal process usually well developed and of varying shape (figs. 15–16)... Gryllotalpa s. l.

- Transversal sclerites of the epiphallus triangular, epiphallus s. s. tongue-shaped, almost as wide as it is long. Ectophallus: latero basal sclerite present, internal process finger-shaped (figs. 11–14)............................................... 5

5. Basal sclerite of the epiphallus a little longer than it is wide, apical sclerite truncate and with no lateral projections. Ectophallus narrow, basal plate oval-shaped, not elongated, internal process three times longer than it is wide (figs. 11–12).... Neocurtilla

- Basal sclerite of the epiphallus longer than it is wide, apical sclerite truncate and with lateral projections. Ectophallus wide, basal plate circle-shaped, elongated, internal process three times as long as it is wide (figs. 13–14).... .. Undescribed genus.
