Hymenopterous wasps are the principal parasitoids of bruchids, principally
species of Braconidae, Encyrtidae, Eulophidae, Eupelmidae, Eurytomidae and
Pteromalidae. From the braconid wasps, the genus Glyptocolastes Ashmead,
Heterospilus Haliday,StenocorseMarshand UrosigalphusAshmeadhaveawide
rangeofbruchidsasanaturalhost(CenterandJohnson, 1976; HetzandJohnson,
1988; Marsh 1979, 1997; Steffan 1981). High number ofhosts reported for the
hymenopterous is given principally for its "host specificity to a particular envi-
ronment, not a particularbeetle" (Hetz and Johnson, 1988).
Systematic andbiological hostsassociations ofUrosigalphus species hasbeen
published for Gibson (1972a, 1972b, 1982; Hetz and Johnson, 1988), they stat-
ed that 19 species are distributed in Mexico. Urosigalphus belongs to the tribe
Brachistini ofsubfamily Helconinae, and can be characterized as egg-larval par-
asitoid (Sharkey, 1996), which is reported in a undetermined species of Vrosig-
alphus from Costa Rica (Traveset, 1991). According to Romero (2002), in his
work about Mexican bruchids, 59 specimens ofhymenopterous wasps that were
reared from bruchids infesting Fabaceae pods and Convulvulaceae seeds, all
belongs to the braconid genus Urosigalphus.
In the present work new distribution record and host associations data for
Urosigalphus (Bruchiurosigalphus) mimosestes Gibson are given; besides new
distribution records of U. (Microurosigalphus) neomexicanus Crawford for the
country. The records presented here are based on material principally deposited
intheColeccionde InsectosdelCentredeEntomologiayAcarologia, Montecillo
(CEAM); and some material borrowed from Texas A&M University, College
Station (TAMU) entomological collection.

Subfamily Helconinae
Urosigalphus (Bruchiurosigalphm) mimosestes
The hypothesis of the host specificity to a particular enviroment of Hetz and
Johnson (1988) can be partially corroborated with this work. Urosigalphus
mimosestes has the capacity ofattacking at least five species ofbruchids associat-
ed to four host plants (Table 1), and probably have a widerhost range.
This species has been reported from the Mexican states ofDistrito Federal and
Morelos (Gibson, 1972b; Figueroa and Romero, 2002), but now are reported from
six Mexican states (Durango, Guanajuato, Hidalgo, Morelos, Nayarit, and Puebla)
expanding the distribution ofthe species across the country.
Host plant
Vol. 115. No. 3, May&June2004 1_T
This species was originally described from New Mexico, USA (Crawford, 1914).
These have since been recorded from Arizona, Colorado, Illinois, Iowa, Kansas,
Missouri, and Texas (Martin, 1956; Gibson, 1972a; Whitfield and Lewis, 2001).
Future additional collections will help determine host and plant relations.
