Alcconotus Pollock & Majka subgen. n.

Type species.

Lacconotus pinicola Horn, by present designation.

Derivation of name.

a partial anagram of Lacconotus , in which its species was formerly placed.

Taxonomic notes.

Pollock (2002) stated that it might be necessary to establish a new genus for the two western species of Lacconotus , although no details were given to justify this possibility. There are many differences between the eastern and western species of Lacconotus (see description above, for Lacconotus ), but the most significant reason for proposal of this new subgeneric name is the structure of the male sex patch, which differs greatly between Lacconotus punctatus and Lacconotus pinicola . It could be argued that this might justify separation into two genera; however, within the related genus Mycterus Clairville (Mycterinae) there are also significant differences in this structure. Also, there are significant differences in the structure of the bursa copulatrix and spermatheca between the two groups (see Figs 13-14); it is impossible to compare these intrageneric differences with other eurypine or mycterid taxa, since the internal female genitalia have yet to be studied in detail in most groups.
