Genus Guides

1

is a of true bugs in the infraorder Leptopodomorpha, commonly known as spiny-legged . The family includes approximately 30 described across five , with distribution primarily in the Old World tropics and subtropics. Members are characterized by their association with moist or aquatic microhabitats, including intertidal zones, rock pools, and riparian environments. Recent taxonomic work has expanded documented ranges, particularly in East and Southeast Asia, with new country records from China, Japan, Laos, Thailand, and Vietnam.

Identification

can be distinguished from other Leptopodomorpha by the combination of: fore with distinct spines or teeth (the basis for the "spiny-legged "); body often dorsoventrally flattened; with ocelli present; and 3-segmented. Male genital capsules and parameres are important diagnostic features at level. The superficially resembles Saldidae (shore bugs) but differs in tarsal segmentation and fore leg armature.

Habitat

vary by and . Patapius spinosus occurs in supralittoral zones of sandy beaches and rocky intertidal areas, hiding under stones and in crevices during low tide. Valleriola species inhabit temporary rock pools on granite outcrops and boulders in rainforest and wet sclerophyll forest environments. Leotichius species have been found in xeric habitats, including areas shared with -lion larvae. Leptopus species are associated with riparian zones.

Distribution

Widespread in the Old World tropics and subtropics, with records from: Mediterranean and North African regions; southern Europe; Middle East; Indian subcontinent; Southeast Asia (Laos, Thailand, Vietnam, Cambodia, Indonesia, Philippines); East Asia (China including Hainan Island, Japan); and Australia (Queensland). Patapius spinosus has been introduced to North America and Chile. The 's known range in China has expanded from the Oriental Region to include both Oriental and Palaearctic Regions.

Behavior

Patapius spinosus has been observed hiding under stones and in crevices during low tide in intertidal . Leotichius schuhi shares habitat with larvae of xeric-adapted -lions (Neuroptera), though specific behavioral interactions have not been documented.

Taxonomic diversity

The comprises five : Leptopus, Patapius, Valleriola, Leotichius, and Erianotus. China records four genera and nine ; recent descriptions include Valleriola asiatica from Laos and Hainan Island, and Valleriola bui from Laos and Thailand.

Conservation of specimens

Valleriola wilsonae specimens from temporary rock pools were noted to be difficult to collect alive due to their rapid movement and the ephemeral nature of their .
