Description.

Female body length: 1.40 mm (n=1). Male body length: 1.19 mm (n=1). Body color: head, mesosoma, and metasoma black.

Head. Color of radicle: yellow. Length of radicle: less than width of clypeus. Color of A1-A6 in female: yellow. Color of A7-A11 in female: brown. Number of basiconic sensilla on A6: 0. Number of basiconic sensilla on A7: 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: uncertain, bulging; uncertain, narrow. Genal carina: absent; present and extending dorsally to vicinity of lower margin eye. Malar striae: absent. Sculpture of malar sulcus: antero-posteriorly striate. Orbital furrow: medially delimited by ridge or carina at midpoint of eye, poorly defined or absent near intersection with malar sulcus. Macrosculpture of frons between antennal scrobe and anterior ocellus: absent. Preocellar pit: present. Setation of lateral frons: moderately dense. Punctation of lateral frons: moderately dense. Sculpture directly ventral to preocellar pit: microsculptured. Macrosculpture of lateral frons: absent. OOL: separated by less than one ocellar diameter. Hyperoccipital carina: complete. Macrosculpture of posterior vertex: absent. Microsculpture on posterior vertex along occipital carina: present. Anterior margin of occipital carina: finely crenulate to smooth.

Mesosoma. Epomial carina: present. Netrion sulcus: incomplete. Pronotal suprahumeral sulcus in posterior half of pronotum: clearly indicated by cells. Location of pronotal suprahumeral sulcus: anterior half or pronotum. Number of episternal foveae: 4 or more. Course of episternal foveae ventrally: distinctly separate from postacetabular sulcus. Course of episternal foveae dorsally: extending to mesopleural pit. Subacropleural sulcus: present. Speculum: transversely strigose. Mesopleural pit: extending ventrally into dorsoventral furrow parallel to mesopleural carina. Mesopleural carina: well defined anteriorly, poorly defined to absent posteriorly. Sculpture of femoral depression: smooth. Patch of striae at posteroventral end of femoral depression: absent. Setal patch at posteroventral end of femoral depression: present. Microsculpture of anteroventral mesopleuron: present throughout. Macrosculpture of anteroventral mesopleuron: absent. Postacetabular sulcus: formed by large cells. Mesopleural epicoxal sulcus: formed by large cells. Setation of posteroventral metapleuron: absent. Sculpture of dorsal metapleural area: absent. Posterodorsal metapleural sulcus: present as line of foveae. Paracoxal sulcus in ventral half of metapleuron: indicated by a line of elongate cells. Anteroventral extension of metapleuron: not extending to base of mesocoxa. Metapleural epicoxal sulcus: present as coarse rugae. Mesoscutal humeral sulcus: indicated by a line of cells. Median mesoscutal carina: absent. Macrosculpture of mesoscutum: weakly rugulose posteriorly. Pattern of mesoscutal microsculpture: uniform throughout. Mesoscutal suprahumeral sulcus: comprised of cells. Length of mesoscutal suprahumeral sulcus: about half the length of anterolateral edge of mesoscutum. Parapsidal line: present. Notaulus: indicated only at posterior margin of mesoscutum. Median protuberance on anterior margin of mesoscutellum: present. Protruberance on anterior margin of mesoscutellum directly posterior to notaulus: present. Shape of dorsal margin of anterior lobe of axillar crescent: round. Sculpture of anterior lobe of axillar crescent: dorsoventrally strigose. Area bounded by axillar crescent: punctures visible in at least ventral half, not quite striate. Macrosculpture of mesoscutellum: absent. Microsculpture on mesoscutellum: present throughout. Setation of posterior scutellar sulcus: present. Form of metascutellum: multiple rows of cells. Metanotal trough: foveate, foveae occupying more than half of metanotal height. Metapostnotum: invaginated near lateral edge of metascutellum. Length of postmarginal vein: about twice as long as stigmal vein. Color of legs: coxae brown, legs elsewhere yellow. Anteromedial portion of metasomal depression: smooth.

Metasoma. Longitudinal striae on T1 posterior to basal costae: present. Number of sublateral setae (on one side): 0; 1. Setation of laterotergite 1: absent. Longitudinal striation of T2: present in anteromedial portion of the tergite. Setation of T2: present throughout area posterior to striae. Setation of laterotergite 2: present. Striation of S2: present in anterior half of sternite not covered by laterotergites. Setation of S2: sparsely present throughout area not covered by laterotergite.

Diagnosis.

Trissolcus gonopsidis is a distinctive species: the facial striae of T. gonopsidis are robust (Figures 73-76 ) and, in combination with episternal foveae distant from the postacetabular sulcus (Figure 74 ), separate it from other species of the flavipes group.
