ABBREVIATIONS 



The letter "t" written to the right and above an Arabic numeral indicates 



the tergite, while the letter "s" indicates the sternite of the segment in 



question. 



a Apical appendage (apicappendix) of claspers. 



ae Aedeagus or intromittent organ (penis, etc.). 



b Penis thread of aedeagus (penisfilum or spirofilum). 



c Cerci (parapodial plates in some cases). 



CO Columna, or part of aedeagus. 



dv Dorsovalvae, or dorsal valves, possibly homologous with the struc- 

 ture labeled "s". 



ea Epiandrium, or ninth tergite located above male genitaha. 



en Penisvalvae or aedeagus. 



ex Gonostyli, or genital styles (also called gonopods) possibly homol- 

 ogous with crustacean exopodites. 



gs Basistylus or basal segment of genital style (also called gonostipes). 



h Dististj-lus, or distal segment of genital style (also called cochliarium 



harpes, harpagones, parameres, etc.). 



lia Hypandrium, or ninth sternite beneath male genitalia. 



liv Hypovalvae, or valves of the hypandrium, located beneath male 



genitalia. 



il) Interbasales, or interbasal plates which may unite to form the inter- 

 basis, or connective, between the bases of the genital styles. The 

 label "ib?" indicates the parapenes, or processes which are not 

 strictly homologous with the other structures labeled "ib." 



p Gonocoxite, or genital coxite, homologous with crustacean proto- 



podite. 



pa Parandrium or pleural plate lateral to male genitalia. 



})g Proctiger, or anus-bearing structure; also suranal plate or epiproct. 



pp Paraprocts, or parapodial plates, homologous with Crustacean pro- 



topodites. 



pr Same as pp. 



ps Pseudostyli, or valves of eighth sternite. 



pv Penisvalvae or aedeagus. 



s Possible homologue of the sagittae of higher Hymenoptera. 



sa Subapical api)cndix (subappendix) of claspers. 



sb .Surbasale, or surbasal plate. 



sg Surstyli, or surgonopods (secondary claspers above genital styles). 



sp Syncoxite, or united genital coxites (proto{)odites), also called 



gonocardo. 



sr Stj'loreceptor, or plate of female for reception of male stjde. 



ta Telaedeagus, or terminal portion of aedeagus. 



tm Tectum, possible homologue of tegumen of higher Lepidoptera. 



vv . . . . . Ventrovalvae, possible homologues of volsellae of higher lI^Tnenop- 

 tera.
