Key to genera of the subfamily Rhaphidophorinae

1. Male abdominal tergite without obvious process on dorsal surface............................................... 2

- Male abdominal tergite with obvious process on dorsal surface.................................................. 3

2. Male epiproct strongly modified, basal area with 1 pair of large processes directed posteriorly and slightly upwards, the apex with 1 long process ventrally................................................ Neorhaphidophora Gorochov, 1999

- Male epiproct weakly specialized. Fore tibiae with 2 ventral apical spine, male epiproct with one process or posterior margin slightly curved, narrowed or bifurcate, apical area of ventral valvae serrate ventrally; or fore tibiae with 3 or 4 ventral apical spines, male epiproct simple and oval, apical area of ventral valvae smooth ventrally...................................................................................................... Rhaphidophora Audiner-Serville, 1838

3. Male seventh or eighth abdominal tergite with 1 large process, other abdominal tergites with small processes............. 4

- Male ninth or tenth abdominal tergite with 1 large process..................................................... 5

4. Posterior margin of male seventh abdominal tergite with small process in the middle; medial area of eighth abdominal tergite with obvious lobate process, posterior margin slightly concave bearing spine-shaped lateral lobes; ninth abdominal tergite weakly sclerotized on dorsal surface, medial area of posterior margin with 1 small lobe apically upcurved; posterior margin of epiproct bifurcate. Female eighth abdominal tergite with a rather small, roundly angular median process. The apices of rostral tubercles of head touching one another basally and divided apically. The genus includes four species, but only one male sex is known ( Eades et al., 2016; Gorochov, 2010b)................................... Minirhaphidophora Gorochov, 2002

- Posterior margin of male seventh abdominal tergite with a large median process; posterior margin of ninth and tenth abdominal tergite with small median process or absent; epiproct simple, without large outgrowths......... Stonychophora Karny, 1934

5. Male ninth abdominal tergite with a large median process on posterior margin; seventh and eighth abdominal tergites only with a small median process more or less angular or nearly obtusely rounded; epiproct simple, without large outgrowths, teeth or other specializations....................................................... .. Eurhaphidophora Gorochov, 1999

- Male ninth and tenth abdominal tergites with large median process on posterior margin.............................. 6

6. Median process of male ninth abdominal tergite without outgrowths, while tenth abdominal tergite with small outgrowths; other abdominal tergites without any outgrowths; male epiproct large, strongly directing backwards, apical area hooked with some small teeth ventrally. Fore tibiae with 2 ventral apical spines................... Pararhaphiophora Gorochov, 1999

- Median process of male tenth abdominal tergite concave basally, process of ninth abdominal tergite partly or entirely running into the concavity and lateral margins of the process fused with anterior margin of tenth abdominal tergite; epiproct entirely or partly fused with posterior margin of tenth abdominal tergite....................... Diarhaphidophora Gorochov, 2012
