Identification & Distribution

The fundatrices of Ceratoglyphina roepkei feed on snowbell (Styrax paralleloneurus) inducing remarkable multiple-cavity galls (see pictures below of immature and mature galls). The gall looks like a peruke (= periwig) with long curly frizzy hair as in dreadlocks. Each gall consists of several long, slender, tubular subgalls, 15-20 cm long, their bases radiating from an attachment site on the stem near an axil bud. Each subgall is spirally twisted and has a longitudinal suture running from the base to the apex (cf. galls of Pseudoregma sundanica on Styrax paralleloneurus, which comprise up to seven globular sub-galls joined to a swollen central fundatrix's gall; and cf. galls of Cerataphis vandermeermohri on Styrax paralleloneurus, which consist of bunches of long, thin, dichotomously branched tubes).

Note: In the earlier literature Ceratoglyphina roepkei is referred to as Astegopteryx roepkei.

Apterae of Ceratoglyphina roepkei (not pictured) in the gall have a small, broadly oval body with rather long hairs. The antennae have 5 segments, and are without secondary rhinaria. The eyes are comprised of 3 facets. The frons has 2 conical spines. The rostrum reaches to just past the mesocoxae, with the apical rostral segment very acuminate (=tapering to a sharp point). The siphunculi are small, about half as long as wide, and placed on small cones.

The alate of Ceratoglyphina roepkei (not pictured) has a broad head, with very large red eyes. The ocelli are tuberculoid and protruding. The antennae are 0.40-0.44 times the length of the body, they are ringed by very fine spines, and they bear 18-26 secondary rhinaria on segment III, 7-10 on IV and 6-9 on V. The last antennal segment is longer than segment IV (Ceratoglyphina styracicola on Styrax suberifolius which has segment IV longer than V). Fore and midlegs have the first tarsal segment with 4 hairs. The hindleg first tarsal segment has a very short median spine and 2 long hairs. The abdomen has few hairs. Tergites VII & VIII are not thickened or sclerotized, except around hair bases (cf.Pseudoregma sundanica, which has these tergites thickened & sclerotized). The spinal hairs on tergite VIII, and often on VII, are sited on scleroites (cf. Ceratoglyphina styracicola, which has no scleroites on the abdominal tergum). The siphunculi are not placed on sclerotic black plates.

Ceratoglyphina roepkei lives without host alternation on Styrax paralleloneurus. Alate sexuparae have been found in the gall in February. The species has only been recorded in Sumatra, Indonesia.


Other aphids on the same host

Ceratoglyphina roepkei has been recorded on 1 snowbell species (Styrax paralleloneurus).

Blackman & Eastop list 3 species of aphid as feeding on Styrax paralleloneurus worldwide, and provide formal identification keys (Show World list). Of those aphid species, Baker (2015) lists none occurring in Britain (Show British list).


We are grateful to Utako Kurosu & Shigeyuki Aoki for providing images from Aoki & Kurosu (2010) for this page.

We have used the keys and species accounts of Hille Ris Lambers (1932) (as Astegopteryx roepkei) & Aoki & Kurosu (2010), together with those of Roger Blackman & Victor Eastop in Aphids on Worlds Plants. We fully acknowledge these authors and those listed in the reference sections as the source for the (summarized) taxonomic information we have presented. Any errors in identification or information are ours alone, and we would be very grateful for any corrections. For assistance on the terms used for aphid morphology we suggest the figure provided by Blackman & Eastop (2006).
