Cryptocephalus (Burlinius)

Cryptocephalus (Burlinius) fulvus, photographed by Josef Dvořák.


Belongs within: Cryptocephalini.

The subgenus Burlinius of chrysomelid beetles is found widely in the Palaearctic. Burlinius species are generally polyphagous.

Characters (from Erber & Schöller 2006): Comparatively small species (1.9-4.5 mm) of Cryptocephalus, females somewhat larger than males, body shape cylindrical, colour predominantly creamy yellow. Basal segment of antennae long, laterally depressed; second segment small, only about twice as long as wide; following segments elongated and dilated from segment six onwards. Elytra with nine rows of punctures including a marginal row and scutellar row which is shortened and with punctures close. Part of rows near apex fused; punctation of apex sparse and confused. Humerus quite evident. Tarsi, especially fore tarsi, exhibiting sexual dimorphism: segments one and three more or less dilated in male. Claws divergent and simple, base of each slightly extended ventrally. Male: Aedeagus bearing distal dorsal process (appendix dorsalis) covering dorsal opening (orificium) and two symmetrical ventral processes. Weakly sclerotised area present at base of ventral processes, bearing short setae. Endophallus comprising dorsal guiding sclerite, bearing on dorsal side a fine tube which is elevated at its end, containing a thin filum. Tube elevated from guiding sclerite posteriorly, ending in round or slipper-shaped element. Anchoring sclerite present opposite guiding sclerite, resembling a mammal jaw, anterior ending prolonged into one or two tips, posterior ending into two wing-shaped apodemes corresponding with almost wing-shaped apodemes of guiding sclerite. Female: Spermatheca consisting of hook-formed vasculum and thread-like ductus. Part of ductus near vasculum spiralised, near vagina straight. Kotpresse consisting of two dorsal and one ventral sclerite. Dorsal sclerites bent as well anteriorly as in ventral direction; ventrally bent part following lateral fold of intestine; sclerites ending dorsally in sclerotised zone directed toward dorsal fold of intestine. Ventral sclerite a crosswise band ending in two apodemes which are wider than rectum. Sclerotised area near centre of ventral sclerite.
