“…The third segment of the maxillary palpus ( Fig. 36) exhibits six of the eight basic apical sensilla basiconica described by Grimes and Neunzig (1986a); the three smaller probably being the lateral (L1, L2, and L3), the three taller sensilla the apical (A1, A2, and A3) sensilla, and the two medial sensilla basiconica being absent. The dorsoposterior face of this segment was not observed to assess the expected presence of the sensillum digitiformium and sensilla campaniformia (Grimes and Neunzig, 1986a).…”

The current classification of African representatives of the family Saturniidae is largely unsatisfactory and needs to be revised following a proper and rigorous phylogenetic analysis. In this regard, the use of characters of preimaginal stages in phylogeny reconstruction was already emphasized in the literature; however, few details are known about the morphology of the eggs, larvae, and pupae of these moths. To fill this gap and to provide a preliminary basis for further phylogenetic studies, the early stages of Bunaeopsis licharbas, a member of the tribe Bunaeini within the Saturniinae, are described. Egg chorionic ultrastructure, chaetotaxy of the larva in every instar, and morphology of the pupa are described and illustrated. A total of 22 previously overlooked characters was found and their potential phylogenetic significance is discussed in the light of a comparative study which includes a large set of representatives of all five tribes in the subfamily. Until further phylogenetic analyses, some characters are considered to be potential synapomorphies supporting, in particular, the monophyly of the tribe Bunaeini, the close relationship between this tribe and part of the Urotini, as well as the existence of an Afrotropical lineage within the Saturniinae uniting the tribes Bunaeini, Urotini, and Micragonini. In a group of moths whose preimaginal instars are among the best known within the Lepidoptera, the unexpected, and relatively high number of potentially informative characters found by the present study stresses the value of minute and exhaustive descriptive studies to make use of morphological characters available for phylogenetic studies.

Sensilla digitiformia and campaniformia on the tip of the piercing ovipositor ofDyseriocrania subpurpurella(Haworth 1828) (Lepidoptera: Eriocraniidae)

Abstract. The sensilla on the piercing ovipositor of Dyseriocrania subpurpurella are described by means of scanning electron microscopy. Two sensilla types are present: aporous sensilla digitiformia and sensilla campaniformia. This is the fi rst mention of sensilla digitiformia on the ovipositor of a Lepidoptera. The sensilla are arranged in successive pairs on each side of the ovipositor: the sensilla campaniformia are apical, the sensilla digitiformia are subapical. All the sensilla are probably capable of recording both the cuticular stress and the mechanical contact of the ovipositor from the initial through the fi nal steps of penetration in the leaf-host to egg-laying. The different possible roles of each sensillum type are considered in relation with our present knowledge.

“…Accordingly, McIndoo's (1919) "subocellar" pores SOb and SOc, as well as "ocellar" pore Ob (McIndoo, 1929), not mentioned by Hasenfuss (1980), were termed SSb, SSc and Sb, respectively. The terminology of Grimes & Neunzig (1986a, 1986b was followed for the sensilla of the apical segment of the maxillary palp and lobe, as their description is more complete than that of Hasenfuss (1980). For the same reason, Gerasimov's (1952) terminology for the antennal sensilla was used, because he extended Ripley's (1923) nomenclature by naming the antennal pore and supernumerary sensilla basiconica.…”

Abstract. The external morphology and chaetotaxy of the larvae of Heterogynidae (Lepidoptera) are described in order to provide information of potential phylogenetic value for the reconstruction of the systematic relationships within the Zygaenoidea. The most outstanding characteristics of heterogynid larvae are their modified habitus during diapause, the presence of an epipharyngeal lamella, the shape of the prothoracic shield, the presence in the first instar of an organ of unknown function on the middorsum of the mesothorax ("Chapman's organ"), the absence of V2, V3 and Va on the head, the absence of V1 on the prothorax and the presence of two primary setae on the inner side of the proleg, the last trait representing an autapomorphy of the family. A number of possible synapomorphies with the Zygaenidae (e.g. presence of cuticular cavities) suggest a close relationship between these two families, but other larval and adult traits are shared only with the "Phaudinae" and limacodid-group families of the Zygaenoidea (viz. absence of V1 on the prothorax with the "Phaudinae", reduced proboscis and absence of ocelli with them all). Nevertheless, a lack of knowledge of the preimaginal instars of species from some zygaenoid families, and of the homology and polarity of given characters of groups within and outside the Zygaenoidea, hamper a thorough comparison of larvae.
