9: arrow); mesoventrite with promesocoxal foveae and large lateral mesosternal
Body shorter, length <10 mm 5 5 Mesosternal tubercle low, broad, and rounded in profile.
Diagnosis: Laccocoris limicola can be distinguished from its two known congeners in Tanzania by the triangular or acuminate labrum nearly as long as wide and the produced, bluntly acute mesosternal tubercle.
Diagnosis: Laccocoris limigenus can be distinguished from its two known congeners in Tanzania by the triangular or acuminate labrum nearly as long as wide and the low, broad, and rounded mesosternal tubercle.
Pectoral canal on prosternum open behind and passing anterior margin of mesocoxae, rostrum not touching middle coxa, but ending in receptacle on mesosternum, mesosternal process cavernous, forming receptacle, receptacle at least as long as wide, its inner margin U-shaped; mesosternum truncate between middle coxae, width of mesosternum separating middle coxae wider than the dorsal apex of the rostrum (Fig.
29 x) as long as width of the apex of the rostrum, mesosternal receptacle U-shaped and nearly as long as broad and cavernous (Fig.
Nymphs of Cultus can be separated from other North American Perlodinae genera by the combination of the following characters; lacinia bidentate with few marginal setae, pronotal setae restricted to 2-3 at corners, and mesosternal
Yarms well developed, reaching posterior corners of furcal pits, transverse suture connecting furcal pits absent (Stewart and Stark, 2002).
However, it can be distinguished easily from the latter by the absence of a spinula on the mesosternal
Later, Cameron (1934) proposed the new subgenus Acanthophaena under Gyrophaena Mannerheim, based on male characters of abdominal sternite V with lateral margins expanded as a lamelliform process, and with a short mesosternal process.
Mesosternal process with medial longitudinal carina extended to middle of mesocoxal cavity.
