Remarks
Cerurina marshalli is a widely distributed species throughout Sub-Saharan Africa. There are some differences in the external morphology of specimens collected in different regions, for example, specimens from western and eastern Africa having a somewhat narrower antemedial fascia with more undulated margins than topotypical specimens.
Kiriakoff (1963) reported that despite the very wide distribution of this species it does not appear to form geographic races. Despite some minor differences in the habitus of examined specimens collected in different regions of Africa, Kiriakoff’s hypothesis probably does stand true, with there being one continuous population throughout. The male genitalia can be variable, especially the position and size of the terminal spines of the socii and the shape of the uncus tip making it difficult to split the different geographic populations, which is in agreement with Kiriakoff’s concept. It cannot be excluded however that genetic analyses could reveal that there are distinct populations, but such analyses were unfortunately beyond the scope of the current paper.
It should be emphasised that C. marshalli can be externally very similar to species in the genus Afrocerura and that in some regions they are known to be sympatric (see map, Fig. 47). Three species, C. marshalli, A. bifasciata bifasciata and A. cameroona were all recorded from the same light trap over a two day period in Kitwe, Zambia and are likely to be sympatric throughout the northern and eastern parts of the country as well. C. marshalli and A. leonensis are both known from a similar area in West Africa (see examined material below) and it is hypothesised that they too are sympatric and that further sampling in this region will reveal this. In such instances, dissections may be necessary to confirm identifications.
According to the collecting data, C. marshalli is on the wing in the wet season. The syntype from Zimbabwe was collected in February and other material examined from Zambia was collected in February, October, November and December. In Ivory Coast specimens were collected in November (end of rains) and in Sierra Leone in June. Specimens from Tanzania were collected in December which for much of the country is the dry season but in the south of Tanzania (where the specimens are from) it is the rainy season.
It is worth noting that Schintlmeister & Witt (2015) refer to a holotype female despite Hampson clearly stating in the original description that the type series consisted of three males and six females.
Distribution
C. marshalli is known to occur in the Central African Republic, Ivory Coast, Democratic Republic of Congo, Malawi, Mozambique, Namibia, Tanzania, Zambia, Zimbabwe and South Africa (Schintlmeister & Witt, 2015, De Prins & De Prins, 2019). The records for Gabon and Cameroon in Schintlmeister & Witt (2015) likely refer to Afrocerura cameroona (see below). Cerurina marshalli mainly inhabits dry savannah habitats but also occurs in moist forests of high elevation for example in Tanzania and D.R. Congo (Kivu). Specimens collected recently on ANHRT expeditions from Sierra Leone, represent a new country record for this species.
