“…Although not unique in Baridinae, other internal structures are illustrated in Figs 451-459 (according to Snodgrass 1935 andCalder 1989), including the various divisions of the digestive system and the ventral nerve ganglia (Fig. 458).…”

Although the phylogenetic classifi cation of Curculionoidea is still in its infant stages, knowledge of the morphology of this large radiation of beetles also is relatively lacking. Few morphological reviews have been done at the family level, and even fewer have examined the subfamily level and below (beyond description of genital morphology). Morphological studies within the subfamily Baridinae are limited and have mostly been restricted to the study of genital morphology, with a few exceptions. Th is study provides a fairly comprehensive, though by no means exhaustive, review of baridine external and internal morphology to aid future studies on the group, particularly in phylogenetics.

“…The Malpighian tubules are long and cover the entire midgut and hindgut. They are classifi ed as Type II (Calder 1989) since they are clustered in two groups: one containing four tubules that end at the anterior part of the rectum, and the other containing only two narrower tubules that end at the base of the anus. The ileum is located right after the pyloric valve and it ends in a more constricted area (Fig.…”

“…All these regions are involved in ingestion, storage, digestion, absorption and of food and water balance (Borror et al 1976, Calder 1989, Romoser & Stoffolano 1998. There gross morphology and histology of the Scolytinae beetles Scolytus multistriatus Marsham (Baker & Estrin 1974), Dendroctonus group (Díaz et al 1998Silva-Olivares et al 2003), Trypodendron lineatum Oliv., Gnathotrichus retusus LeConte and G. sulcatus LeConte (Schneider & Rudinsky 1969), and Ips pini Say (Coleoptera: Curculionidae) (Hall et al 2002) reported some features of alimentary canal which are useful for taxonomy of these beetles (Lopez-Buenfi l et al 2001).…”

Neotropical Entomology 37(2): 143-151 (2008) Morfología General del Tracto Digestivo y Sistema Reproductivo de Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae, Scolytinae)RESUMEN -El estudio morfológico del tracto digestivo y el sistema reproductor de machos y hembras de Hypothenemus hampei Ferrari se describe a continuación. El tracto digestivo presenta un arreglo típico descrito para otros insectos. Ahora las diferencias morfológicas se encontraron en el buche del estomodeo, en donde se observaron estructuras espinosas y en el mesenteron se observo un número reducido de ciegos gástricos. Se evidenció por primera vez el comportamiento de la alimentación de las hembras de H. hampei, que requiere aparentemente de la ingesta del endosperma del café para poder producir huevos viables durante la oviposición. La presencia de burbujas de aire al interior del ventrículo anterior se cree que puede ser debido al hambre, más que a la respuesta al medio ambiente durante el vuelo como lo indicaban anteriores observaciones. El sistema reproductor de la hembra presenta dos ovarios y un arreglo estructural común a especímenes de la familia Curculionidae. El sistema reproductor masculino mostró una diferencia signifi cativa con respecto a otros miembros de la familia Curculionidae e incluso a otra especie de la tribu Scolytinae presentando un aedeagus esclerotizado compuesto de varios orifi cios en la porción terminal, por donde el esperma se expulsa durante el apareamiento. PALABRAS-CLAVE: Broca del café, morfología interna, comportamiento de alimentación, reproducciónABSTRACT -The alimentary canal and the reproductive tract of males and females of Hypothenemus hampei Ferrari are described. The alimentary canal of H. hampei showed the crop with several spinelike structures and the midgut with few gastric caeca. We evidenced for the fi rst time that adult females need to feed on coffee in order to produce viable eggs before and during oviposition period. The presence of air bubbles inside the anterior midgut may be due to starvation rather than the response of the environment during fl ying as previously reported. Two ovaries and the same structures and arrangements common to individuals of the Curculionidae beetles composed the female reproductive system. The male reproductive tract showed a signifi cant difference with respect to other Curculionidae and even other Scolytinae species as it showed a sclerotized aedeagus with several pore-like structures in the terminal portion where sperm is released during mating.

“…5A) largely resembles that of other weevils described by Calder (1989) as the "fourth group" (p. 1229) with discrete cerebrum, suboesophageal ganglion and prothoracic ganglion, and a compound ganglion comprised of the meso-and metathoracic and the abdominal ganglia.
