Abstract

These two genera Stenodyneriellus Giordani Soika and Lissodynerus Giordani Soika are newly recorded
from China. Three species, namely Stenodyneriellus similiguttulatus sp. n. from Yunnan, S. maolanensis
sp. n. from Guizhou, and S. depressus sp. n. from Yunnan, are described and illustrated. Stenodyneriellus
guttulatus (de Saussure, 1862) and Lissodynerus septemfasciatus feanus (Giordani Soika, 1941) are newly
recorded and illustrated from China. A key to the Chinese species of Stenodyneriellus is provided.

Introduction

‘These two genera Stenodyneriellus and Lissodynerus were established by Giordani Soika
in 1961 and 1994, respectively. Both of them are Oriental and Australian genera of
potter wasps. Some species share the following characters: T2 with a lamella apically,
shelf of propodeum developed dorsally, pronotal carina complete and rounded dor-

sally, T1 slightly narrower than T2. To date, Stenodyneriellus includes 59 species with
five subspecies and Lissodynerus contains 17 species with eight subspecies worldwide
(Giordani Soika 1961, 1993a, 1993b, 1994, 1995, 1996; Borsato 1994, 2003; Gusen-
leitner 2007, 2008, 2013; Girish Kumar and Carpenter 2015). Giordani Soika (1994)
provided a good basis for further taxonomic study of Stenodyneriellus and Lissodynerus,
and hereafter a few new species have been described by Borsato (2003), Gusenleitner
(2007, 2008, 2013), and Girish Kumar and Carpenter (2015). Among the known spe-
cies of these two genera, not one was reported from China. In our study of the eume-
nine wasps from China, four species of Stenodyneriellus and one species of Lissodynerus
were collected. And as a result of careful comparisons with all known species, three
new species of Stenodyneriellus are described and illustrated in detail, and S. guttulatus
(de Saussure, 1862) and L. septemfasciatus feanus (Giordani Soika, 1941) are newly
reported and illustrated from China. A key to the Chinese species of Stenodyneriellus is
provided. The key was produced based on both the examination of specimens and the
information extracted from the literature.

Materials and methods

The specimens examined are deposited in the Institute of Entomology and Molecular
Biology, Chongqing Normal University, Chongqing, China (CQNU) and Depart-
ment of Entomology, College of Plant Protection, Yunnan Agricultural University,
Kunming (YNAU). Descriptions and measurements were made under a stereomicro-
scope (Nikon SMZ1500), and all figures were taken with a stereomicroscope (LEICA
EZ4HD) attached to a computer using Leica Application Suite version 2.1.0 software.
The ratios used throughout the descriptions were measured in the same magnifying
multiple of stereomicroscope. All measurements were taken as the maximal length
of body parts measured. Body length was measured from the anterior margin of the
head to the posterior margin of metasomal tergum 2. For the density description of
punctures, “sparsely” means that interspaces are larger than one puncture diameter,
“moderately” means equal to the diameter, and “densely” means less than one diam-
eter. Terminology principally follows Carpenter (1982) and Carpenter and Cumming
(1985). The abbreviations used in the text are shown as follows:

Al for antennal segment 1,
A2 for antennal segment 2,
POD _ for postocellar distance,
OOD for the minimum distance between the compound eye and posterior ocellus;

Tl for metasomal tergum 1,
2 for metasomal tergum 2,
S1 for metasomal sternum 1,

S2 for metasomal sternum 2, and so on.

Etymology. ‘The specific name is derived from two Latin words: de- and pressus,
referring to S2 of the species being distinctly depressed basally.

Lissodynerus Giordani Soika, 1973: 119, used as generic name for Odynerus septemfas-
ciatus var. feanus Giordani Soika, 1941. Unavailable under Article 13.1.1 of the
Code.

Trichodynerus Giordani Soika & Kojima, 1988: 178, used as a generic name in the

able under Article 13.1.1 of the Code.

Type species. Odynerus septemfasciatus Smith, 1857, by original designation.

Diagnosis. Carina of pronotum well-developed, wide rounded, and regularly con-
vex (Fig. 32) dorsally; shelf on the upper propodeum more or less developed, and
sometimes confused with big and dense punctures on the interface between dorsal and
posterior surfaces, dorsal and posterior surfaces clearly separated, posterior surface en-
tirely concave (Fig. 33); T1 short, width approximately 2 x its length, with an vertical
and slightly convex surface anteriorly, interface between anterior and dorsal surfaces
with a transverse, smooth, and well-developed carina (Fig. 33); apex on each of T2-T3
or 12-14 with a brown or black blade-shaped lamella (Fig. 35).

Distribution. Oriental and Australian Regions.

blade-shaped lamella (Fig. 35); mesosoma almost entirely black and only with the fol-
lowing yellow parts: a short band on the anterior surface of pronotum medially (Fig.

band on dorsal surface of propodeum laterally (Fig. 33); metasoma largely with yellow

spot on the base of S2 laterally, and irregular spots on apical margins of S2—S4 laterally.
Distribution. China (new record: Guangxi); Myanmar; Vietnam; Malaysia.

Remarks. These female specimens of Lissodynerus septemfasciatus feanus from
China are almost same as those from Myanmar, Vietnam and Malaysia (Giordani
Soika 1994). Male specimens have not been found yet.

Discussion

It is well known that species of these two genera Stenodyneriellus and Lissodynerus occur
in Australian or Oriental region. In China, southern and southwestern provinces typi-
cally belong to the Oriental region, including Guangdong, Guangxi, Hainan, Fujian,
Guizhou, Sichuan, Chongqing and Yunnan. It proves that our results are reliable. We
also believe that in future, more species or distributions of these two genera may be
recorded from the provinces of China belonging to the Oriental region.
