Introduction

This small group of thalassinidean shrimps includes three genera found in the tropical eastern Atlantic and Indo-west Pacific Oceans. Only one species,Thomassinia aimsae Poore, 1997, has been described from Australia. Poore (1997) reviewed the family, and Poore (1994) provided a key to genera. Poore (2015) synonymised Callianideidae and Thomassiniidae.

Diagnosis

Firm-bodied or soft thalassinidean shrimps. Rostrum absent or present only as sharp spine. Linear thalassinica lateral to eyestalks, complete or incomplete. Cephalothorax usually broad, ending posteriorly as a median convexity not separate from posterolateral margins of carapace. Without anterolateral lobes on abdominal somite 1, anterodorsal tergite weak; no thickening of posterolateral carapace margins. Thoracic sternite 7 broad, visible between coxae of pereiopods 4 only as a flat plate. Coxae 4 flattened, immobile, without condyle with thoracic sternite 7. Abdominal somite 1 almost as long as abdominal somite 2 and with pleuron broadly rounded (rarely acute). Abdominal somite 2 pleuron not overlapping abdominal somite 1. Cephalothorax, rostrum, abdomen, telson and all limbs without armature. Anterior cephalothorax and at least abdominal somites 1 and 6, sometimes other, with weak lateral setal rows; lateral surfaces of propodi of pereiopods 2–4 sometimes with similar setal rows. Antenna 1 peduncle article 1 as long as 2 and 3. Antenna 2 with scaphocerite minute, barely articulating. Mandibular incisor toothed anteriorly and posteriorly, symmetrical. Maxilla 2 scaphognathite with one long setae extending into branchial chamber. Maxilliped 3 pediform, sometimes specialised; exopod present or absent. Pereiopods 1 unequal; merus ovate, with convex posterior margin; proximal part of propodus broad (about as long as wide); fingers shorter than proximal part. Pereiopod 2 chelate. Pereiopods 2–4 with flattened propodi. Pereiopods 3 and 4 propodi (or at least 3) bearing single distal spiniform seta on lower margin. Epipods linear, reduced anteriorly; podobranchs rudimentary or absent; two arthrobranchs various, present, reduced or lost; pleurobranchs absent. Male pleopod 1 absent. Appendix masculina fused to appendix interna (rarely separate). Pleopod 2 not modified, similar to pleopods 3–5; all with foliaceous rami, and well-developed appendix interna. Uropodal exopod without transverse suture; endopod more or less ovate. (After Poore 1997).
