New Caledonia is home to many endemic species of plants and animals. Here, we improve our grasp on that biota by describing five new species of armored scale insects in the genus Andaspis: Andaspis brevicornutasp. n, A. conicasp. n., A. nothofagisp. n., A. novaecaledoniaesp. n., and A. ornatasp. n. Each is known exclusively from collections on southern beeches (Nothofagus spp.) in New Caledonia...

The aggregation and mating behavior of the stink bug, Euschistus conspersus Uhler (Hemiptera: Pentatomidae) was investigated in a series of field and laboratory experiments. Marking of E. conspersus mating in aggregations in the field demonstrated that both sexes mate multiple times within aggregations on successive nights and with different partners, although ≈ 20% of the individuals of both s...

Two new species of armored scale, Megacanthaspis hangzhouensis Wei & Feng, sp. n. and Megacanthaspis hainanensis Wei & Feng, sp. n. are described and illustrated from specimens collected from China. A key to adult female of Megacanthaspis species is provided.

It is hypothesised here that some mealybug (Pseudococcidae) and root mealybug (Rhizoecidae) prepupae and pupae are mobile. The prepupa and pupa of the mealybug Promyrmococcus dilli Williams and the prepupa of the root mealybug Ripersiella malschae (Williams) are described and illustrated and their probable mobility is discussed. It is also suggested that the prepupae and pupae of the mealybug M...

In the Japanese typhlocybine fauna, three already known and three newly recorded species of the genera Anufrievia, Empoascanara, and Anzygina are redescribed and reported with brief notes on their taxonomy and biology: A. akazu (Matsumura), A. ciconia Dworakowska, E. bisignatella (Matsumura) comb. nov., new record, E. kotoshonis (Matsumura) new record, E. sonani (Matsumura) and A. honiloa (Kirk...

Two new species of Portanus Ball, 1932 are described and illustrated from Brazil. P. hastatus sp. nov. from Ceará State, can be recognized by its acute pygofer apex and aedeagus with pair of apical processes directed dorsally. Portanus phoenicius sp. nov. from Piauí State, can be recognized by its rounded pygofer lobe with dorsal tooth turned inwardly, aedeagus apex with pair of elongate proces...
