REVISION OF COELIDIIN AE 23 



Sandersellus carinatus DeLong; DeLong, 1969 : 464. Length: <$ 7-50 mm, $ unknown. 



Colour fuscous throughout except for clypeus and clypellus, with prominent irregular ivory 

 spots on elytra and hind wings, veins marked with small circular yellow to orange spots; head, 

 pronotum and scutellum marked with irregular yellow to ochre spots; clypeus and clypellus 

 yellow-ochre except for fuscous markings along lateral margins. 



Head much narrower than pronotum, greatest width about two-thirds greatest width of 

 pronotum; crown long and narrow, produced beyond anterior margin of eyes, distal length 

 about one-third entire median length, lateral margins strongly carinate, disk elevated above 

 level of eyes; eyes large, elongate-ovoid, occupying a greater portion of the head dorsally; 

 pronotum large, bicarinate laterally, strongly carinate medially; scutellum large, median length 

 about equal to median length of pronotum; elytra and hind wings well developed, appendix 

 well developed, venation as in generic description. 



Pygofer in lateral aspect with a short finger-like process arising about middle of caudal 

 margin, caudodorsal margin produced distally to a broad truncate lobe; aedeagus tube-like, 

 broadly sinuate in lateral aspect, curved distally; gonopore subterminal, exiting ventrally; 

 style in dorsal view large, curved slightly laterally with a prominent lateral projection 

 subapically; connective as in generic description; plate long, broad medially. 



Distribution. Peru. 



Specimens examined. 



Sandersellus carinatus DeLong, holotype <$, Peru: Sinchona, vii.1944 (J. G. 

 Saunders) (OSU, Columbus). DeLong's (1969 : 465, figs 4a, 4b, 4c) illustrations 

 of 'Sandersellus carinatus DeLong' were based on a paratype specimen, which I 

 have described herein as retrorsus sp. n. 



The type-series of carinatus is mixed. Two paratype males are each described 

 as new species in this paper. 



Biology. Unknown. 



Remarks. Sandersellus carinatus has a distinctive narrow, tube-like aedeagus 

 which can distinguish the species from all others known in the genus. 



Sandersellus simplex sp. n. 



(Text-figs 27-32) 



Length: $ 7-50 mm, 9. unknown. 



General habitus as in carinatus. 



Pygofer in lateral aspect with curved finger-like process arising above middle of caudal 

 margin, caudodorsal margin produced distally to a broad truncate lobe similar to carinatus; 

 aedeagus broadly sinuate in lateral aspect, curved distally, shaft without barbs, processes or 

 serrations, broad at basal half becoming attenuated apically in dorsal and lateral aspects; 

 gonopore subapical, exiting ventrally; style in dorsal aspect long, curved laterally with a 

 prominent lateral projection subapically; connective as in generic description; plate as in 

 carinatus.
