Appendix 1 : Key to known southern California sculpin larvae (preflexion stage) 



Comments: The following key is provided as a guide to identifying known Southern California sculpin larvae. 

 Some larvae may not key out exactly due to variation in pigment or because they are a species that is not de- 

 scribed yet (see table at end of key). Types (e.g., Artedius type 16) are named as they are labeled in the LACM 

 collection. Equivalent types in literature are noted. 



1 Wings (gut diverticulae) present 2 



Wings absent (or as bumps only) 4 



2(1) Postanal ventral melanophores 3-12 3 



Postanal ventral melanophores 22-32 Artedius lateralis 



3(2) Nape pigment present; myomeres 32-35 Artedius type 16 



(= Artedius type 3 (Washington 1986); may be either A. corallinus or A. notospilosus) 



Nape pigment absent; myomeres 36-37 Artedius type A 



(= undescribed; has wings like other Artedius, no nape pigment, and only 3-8 PAVM) 



4(1) Body covered with melanophores 5 



Body melanophores restricted to ventral midline, gut, nape or head region 9 



5(4) ~26-28 myomeres; stubby body (hatches at 6-7 mm) Rhamphocottus richardsonii* 



36-41 myomeres; elongate body 6 



6(5) Elongate pectoral fin (>20% of the body); pigment extending into dorsal and anal finfold 



(hatches at ~7-9mm) Nautichthys oculofasciatus* 



Pectoral fins not elongate (<15% of body); no pigment extending into fins 7 



7(6) Lateral body relatively unpigmented; preanal length 36-42% of notochordal 



length Hemilepidotus spinosus 



Lateral body covered with melanophores; preanal length ~44-46% of notochordal length 8 



8(7) Series of elongate melanophores present along the lateral midline; pointed snout Radulinus sp. 



No distinct series of elongate melanophores along the lateral midline; blunt 



snout Scorpaenichthys marmoratus 



9(4) Otic capsule pigment present (may be present in Paricelinus hopliticus) 10 



Otic capsule pigment absent 11
