FIRST STAGE LARVA OF CORONIS SCOLOPENDRA LATREILLE (STOMATOPODA: NANNOSQUILLIDAE)

FIRST STAGE LARVA OF CORONIS SCOLOPENDRA LATREILLE (STOMATOPODA: NANNOSQUILLIDAE) During early studies on the biology of Brazilian callianassids (Rodrigues, 1965, 1966, 1971), several specimens of the ly- siosquilloid stomatopod Coronis scolopen- dra Latreille, 1828, were captured inciden- tally while collecting the callianassid decapod Callichirus major (Say, 1818) near Sao Paulo, Brazil. This was due in part to the remarkable similarity between the bur- row openings of these two sand-dwelling in- tertidal crustaceans. The burrow opening of an adult C. scolopendra differs from that of C. major only by its slightly larger diameter, about 10 mm, and moderately oval outline (Rodrigues and Shimizu, 1988). On 24 July 1966 a female, together with its egg mass, was captured. The eggs were placed in petri dishes and cared for in the same way as were the eggs of C. major (see Rodrigues, 1976). In a few days the larvae hatched, but all died without molting to the second stage. So little is known about stomatopod lar- vae that we believe it is useful to present here an account of this first stage larva.

Abstract

During early studies on the biology of Brazilian callianassids (Rodrigues, 1965, 1966, 1971), several specimens of the ly- siosquilloid stomatopod Coronis scolopen- dra Latreille, 1828, were captured inciden- tally while collecting the callianassid decapod Callichirus major (Say, 1818) near Sao Paulo, Brazil. This was due in part to the remarkable similarity between the bur- row openings of these two sand-dwelling in- tertidal crustaceans. The burrow opening of an adult C. scolopendra differs from that of C. major only by its slightly larger diameter, about 10 mm, and moderately oval outline (Rodrigues and Shimizu, 1988). On 24 July 1966 a female, together with its egg mass, was captured. The eggs were placed in petri dishes and cared for in the same way as were the eggs of C. major (see Rodrigues, 1976). In a few days the larvae hatched, but all died without molting to the second stage. So little is known about stomatopod lar- vae that we believe it is useful to present here an account of this first stage larva.
