Hadronotus insulare species group

Diagnosis (Based on Masner 1975, 1983)

Eyes with dense setae; lateral ocelli not contiguous with orbits, away from orbits, sometimes more than MOD; clypeus small, corners not pointed; facial striae absent; hyperoccipital carina present; sculpture of frons, vertex and gena generally with polygonal cells bearing rugose sculpture; frontal depression margined by submedian carina; epomial carina generally absent; mesopleural carina generally present, short and indicated ventrally; marginalis shorter than stigmalis; postmarginalis either absent or shorter than stigmalis, rarely equal to stigmalis; T2 remarkably long, at least 4× as long as T3. No brachypterous forms.

Hosts. Reduviidae ( Hemiptera ): Triatoma rubrofasciata , T. maculata (Erichson, 1848) and T. phyllosoma (Burmeister, 1835) have been recorded as hosts of H. triatomae ; while Linshcosteus sp. was the only species found to be the host of H. linshcostei ( Simmonds 1971; Bertram 1973; Masner 1975; Sankaran and Nagaraja 1975).

Masner (1983) observed that the vast majority of specimens of H. insularis collected from Trinidad (West Indies) were found in yellow pan traps, indicating that the hosts were present close to the ground, possibly in hemipteran eggs laid on plant parts close to the soil. In stark contrast, he found males in large numbers in Malaise traps.
