Number of basiconic sensilla on A 7: 2. Facial striae: present as short grooves. Number of clypeal setae: 2. Microsculpture on gena directly above mandibular condyle: present. Shape of ventral gena in lateral view: narrow. Genal carina: present and extending dorsally to vicinity of lower margin eye; present only at base of mandible. Malar striae: absent. Sculpture of malar sulcus: antero-posteriorly striate. Macrosculpture of frons between antennal scrobe and anterior ocellus: parallel arcuate rugae. Preocellar pit: present.

Metasoma. Longitudinal striae on T 1 posterior to basal costae: present. Number of sublateral setae (on one side): 0; 1. Setation of laterotergite 1: absent. Longitudinal striation of T 2: present in most of tergite, extending posteriorly to transverse line of setae. Setation of T 2: present in a transverse line posteriorly. Setation of laterotergite 2: present. Posteriorly directed setae on medial S 1: present. Striation of S 2: present laterally and in anterior half of median third. Setation of S 2: present throughout area not covered by laterotergite.
diagnosis
Diagnosis. The arched rugae on the frons of Trissolcus cultratus separate it from most species of the flavipes group, but it is shared with T. exerrandus and T. corai. Trissolcus exerrandus has densely setose eyes whereas those of T. cultratus are essentially bare. The orbital furrow in T. corai is well defined ventrally and that of T. cultratus is not (compare Figures 37, 38 to Figures 44, 45).
