Genus Bonnierilla Canu, 1891

Diagnosis: Body form generally swollen, compressed. Prosome consistingof cephalosome and unsegmented metasome (comprising fused first to fourth pedigerous somites) forming brood pouch: fifth pedigeroussomite fused with metasome. Freeurosome 5-segmented, consistingof genitalsomiteand 4-segmented abdomen. Caudal ramus typically with 6 setae, sometimes with 1 clawand 5 setae.Antennulemost commonly 8-segmented, ranging from 6- to 9-segmented. Antenna 4-segmented; basis typically with setal vestige(s) representing exopod; compound distal endopodal segment usually elongate. Mandible with 5 setaeon exopod; endopod 2-segmented usually with 4 setaeon first segment and 9 setaeon second. Maxillule with 9 or 10 setae on arthrite, 1 on coxal endite, 2 on epipodite, 3 on basis, and usually 4 (rarely 3) on exopod and endopod. Maxilla 5-segmented; first endite of syncoxawith 3 (rarely 4) setae; endopod 3-segmentedwith 1, 1, and 3 setae on first to third segments, respectively. Maxilliped 2-segmented, armedwith 10 medial setae on first segment and 2 setae on second. Legs 1–4 with 3-segmented rami. Innercoxalsetaabsentinlegs 1 and 2. Leg 1 with 5 or 6 setae on third endopodal segment. Leg 5 consisting of protopod bearing outer seta and free exopodal segment bearing 1 or 2 setae.

Type species: Bonnierilla longipes ( Kerschner, 1879) by original monotypy.

Remarks. The genus Bonnierilla was established by Canu (1891) to accommodate Paryphes longipes Kerschner, 1879 , since Kerschner’s Paryphes was preoccupied by Paryphes Burmeister, 1835 (Hemiptera) . It currently comprises 12 valid species, two of which are removed here and transferred to a new genus. Four of the remaining ten species are redescribed here based on the study of new material and an additional nine new species are described.
