be apically laminate, or may bear a basal mesal branch. Anterior 
gonopod sternum bandlike and well-sclerotized. Posterior gonopods 
three-segmented, coxal segment with large, prominent colpocoxites 
characterized by a basal flagellar branch usually more or less sheathed 
by a development from the main part of the colpocoxite. Apical two 
segments typical for family. Posterior gonopod sternum with a T- 
shaped process between the coxae in most species. Third and fourth 
legpairs of males enlarged, strongly bowed, but with, at most, small 
mesal femoral knobs. Legpairs 5-7 either normal in size and form, 
or decreasing from slightly enlarged to normal in size. Prefemora of 
male legpair 1 1 with mesobasal processes. Female genitalia without 
any useful taxonomic characters. 
Remarks: Bollmanella is clearly related to Taiyutyla, with which 
it is entirely sympatric, and often syntopic. However, the uniformly 
smaller size, the flagellar branch of the posterior gonopods, and the 
T-shaped process of the posterior gonopod sternum clearly set Boll- 
manella species apart as a distinct phyletic line. 
I would like to comment further on the Family Conotylidae as 
a whole, but several factors preclude it at this time. The genus 
Taiyutyla remains to be revised, and is affected by, as are any con- 
clusions about Conotylidae at this time, the description by Loomis 
and Schmitt (1971) of several extremely interesting new higher taxa 
related to conotylids, including new subfamilies and a new family. 
The Taiyutyla material I have examined so far will also enable me, 
in this projected future paper, to comment in detail on the functional 
aspects of the gonopod complex. 
I am still unable to find any taxonomically useful characters that 
will allow reliable separation of females of the various species of 
conotylids, and members of Bollmanella are no exception. However, 
in the hope that some usable characters might turn up in the future, 
I have designated bona fide female paratypes where possible. I do not 
present a key to the eight known species, as they can readily be sep- 
arated by reference to the illustrations of the gonopods. The gono- 
pods of these species are so small they must be mounted on slides 
temporarily (in glycerine) to see detail.
