Lasiocampa theorini
Aurivillius, 1891
,
Entomologisk Tidskrift
,
12
; 228, pl.2, fig.3.
Type
locality: Gabun [
Gabon
]; based on the whereabouts of
Fritz Theorin
in the 1880’s, “Gaboon”, as the label of the specimen reads, refers to the mouth of the “Gaboon River”, or the modern- day
Gabon
Estuary
at
Libreville
.
Type material.
Syntype
♂
in SMNH with the following labels: “
Lasiocampa
/ Theorini / Auriv. typ.” // “Gaboon” // “Theorin.” (examined).
Taxonomic note.
In the original description of
L. theorini
, only the binomial combination and the locality were given in the legend for the plate on which a drawing of a male of this new species was figured. A male type, with labels that matches collector and locality mentioned by Aurivillius, is known from the SMNH and we consider this to be a
syntype
, probably the only one. Aurivillius described this species in full the year after, in 1892, in
Entomologisk Tidskrift
,
13
: 198, noting and also describing a female from Staudinger’s collection. Moreover,
Hering (1937: 241
, pl. IX, fig.4) figured a “
♂
(Type,
Berlin
Museum)”.
However
, neither the female described in 1892 by
Aurivillius
, nor the male figured by
Hering
in 1937 were mentioned in the original description and thus they cannot be considered types
.
Additional material examined.

There are two dissection-confirmed male specimens of
A. theorini
in
NHMUK
from “
South Africa
” which are clearly
patria falsa
. Both specimens have the accession number B.M.1926-239 which refers to a large collection of
Lepidoptera
purchased from the natural history dealer Frederick Henry Rosenberg containing part of Colonel Charles Swinhoe’s collection. The handwriting on the labels matches that of Swinhoe, who was renowned for his work on the Asian lepidoptera fauna, and it is likely that the mislabelling event took place before the collection ended up in the hands of Rosenberg and
NHMUK
.
Description
Male.
Forewing length
18
—
22.5 mm
. Head, collar, tegula, and thorax beige to tawny brown. Antenna bipectinate; antennae and palps ochreous yellow. Legs beige laterally with sparse dark scale spots, ochreous yellow medially. Abdomen uniformly cream to ochreous beige, sometimes with a few, irregular dark scales. Forewing. Broad, rounded; ground colour beige to tawny-brown, although slightly paler from post-medial line to outer margin; wing speckled sparsely with dark scales that are mostly concentrated along costal margin and near thorax. Post-medial line grey, with scaling extending on the veins distally; post-medial line kinked at vein M1 near outer margin. Postmedial area with a diffuse grey-brown triangular patch between veins R3 and M1; discal spot light beige, rounded, with diffuse margin. Fringe long, slightly darker than ground colour, cilia sometimes black in distal half. Hindwing. Rounded, with undulate margin at tornus. Ground-colour same as forewing or slightly paler beige; medial line dark grey-brown, wider than that of forewing. Sparse dark scales concentrated in the distal half. Outer margin with a small, diffuse, pale grey-brown triangular patch between veins M1 and M2. Fringe long, slightly darker than ground colour, cilia black in distal half. Underside of wing uniformly pale beige with some irregular clusters of grey scales concentrated mostly along the costal margin of fore- and hindwing. Forewing discal spot traceable. Outer margin with diffuse pale grey-brown triangular patch between veins R3 and M1 on forewing and between veins M1 and M2 on hindwing. Fringe darker than ground colour; cilia sometimes black in distal half.
Female.
Forewing length
26
—
28 mm
. Body and wing colour as in male, varying from beige to tawny brown, but with more numerous dark brown or black scales speckled on fore- and hindwing. Antennae filiform. Forewing. Broad, rounded, slightly more angular at apex than in males. Hindwing. Rounded, with undulate margin at tornus; colour and fringe as in male. Underside of wing paler than upperside, both fore- and hindwing uniformly pale beige with numerous grey scales speckled on both wing sets.

Male genitalia.
Uncus elongate, triangular with truncate apex, heavily sclerotised apically. Tegumen narrow. Transtilla comprised of two long slender, apically pointed posterior processes, and two very narrow, short, apically rounded anterior processes connected medially by a thin membrane. Juxta with large, bilobate base, with small, strongly sclerotised, rectangular process antero-medially, and with two very long, thin, tapering, distally pointed lobes accompanying phallus laterally. Vinculum broad, rounded. Valve variable in length; wide at base, constricted medially, truncate distally with rounded, slightly protruding costal edge. Phallus curved in proximal third, thin, long, proximally surrounded with heavily sclerotised manica fused ventrally to caudal lobes of juxta, weakly sclerotised distally with apical split. Vesica extremely short, membranous.

Female genitalia.
Papilla analis broad, lobed, medially deeply notched, very finely setose. Apophysis posterioris long, narrow, rounded apically. Eighth tergite broad, short, posterior margin evenly convex, anterior margin slightly concave, moderately sclerotised; apophysis anterioris as long as posterior one, narrow, apically hooked. Ostium small, semi-circular, with longitudinally striate, trapezoidal antevaginal plate bearing two rounded posterior protrusions. Antrum extremely broad distally, very short, funnellike, strongly sclerotised; ductus bursae very short, heavily sclerotised; cervix bursae oblong, very heavily sclerotised, corpus bursae membranous, posterior half narrow, tubular; anterior part ovoid. Signum bursae absent.
Taxonomic note.
Dissection of numerous
A. theorini
specimens collected from West, Central, and East Africa revealed the existent of a single widespread taxon. Slight variation was noted in the male genitalia in terms of the length and shape of the distal edge of the valve, although no geographical trends were identified. For example, the majority of specimens from West Africa possess a short valve, almost rectangular in shape, although this was also seen in some specimens from central
DRC
(e.g. CHRY-11-83 and CHRY-11-85). Furthermore,
A. theorini
specimens vary widely in external morphology in terms of size and wing colouration with no obvious geographic clustering or congruence in the genitalia. Without clear geographic circumscription and in the absence of consistent differences in external and genital morphology,
A. theorini
is treated as a widespread species that exhibits high levels of intraspecific variation.
Diagnosis.
The distinctive characters between
A. theorini
,
A. flavoantennata
comb. n.
, and
A. smithi
sp. n.
are discussed under the diagnoses of the latter two species.
Distribution (
Fig. 20
).
This species was previously known from
Cameroon
,
DRC
,
Gabon
,
Ghana
,
Nigeria
and
Uganda
. Through this research, it is now also known from
Angola
,
Cote d’Ivoire
,
Guinea
,
Kenya
,
Liberia
,
Republic of the Congo
,
Sierra Leone
and
Togo
. Based on the locality data of the examined specimens,
A. theorini
is a forest-dwelling species that occurs throughout the Guinean-Congolian rainforests and towards the montane forests of East Africa.
