Description ofPhyllodiaptomus christineae n.sp. from Thailand, and distinction of two subgenera withinPhyllodiaptomus Kiefer,1936 (Copepoda, Calanoida)

Abstract

Phyllodiaptomus christineae n .sp . is described from Thailand . It stands out, in the male, by the shape and the armature of the second exopodite-segment of the right P5 and by the elongate apical process and ornamentation of the second exopodite-segment of the left P5 ; in the female, by the reduced lateral wings of the fifth pediger, and by the form of the genital somite . Together with P blanci, P tunguidus and P longipes, the new species constitutes the blanci-group, here raised to the level of a subgenus (Phyllodiaptomus s .s .) with representatives in Central Asia, China, Borneo and Thailand . A second subgenus (Ctenodiaptomus subgen . nov .) is created to accommodate the four Asian species of the annae-group .

Description of Neodiaptomus Siamensis, a New Diaptomid Copepod (Copepoda, Calanoida) from Temporary Pools in Northern Thailand

“…Although there has been a significant increase in records of freshwater diaptomid copepods in Thailand from 13 (Lai & Fernando, 1981;Boonsom, 1984) to 37 species (Sanoamuang, 2002;Sanoamuang & Teeramaethee, 2006), most have been found in the northeastern region (Dumont & Reddy, 1994;Dumont et al, 1996;Reddy et al, , 2000Sanoamuang, 1999Sanoamuang, , 2001aSanoamuang, -c, 2004Sanoamuang & Yindee, 2001;Sanoamuang & Athibai, 2002;Sanoamuang & Sivongxay, 2004), whereas relatively little is known about the situation in the north. While examining diaptomid copepods from northern Thailand, we came across another new species of Neodiaptomus.…”

A New Species of Phyllodiaptomus (Copepoda, Diaptomidae) From Northeast Thailand

“…Among these, P. praedictus Reddy, 1994 andP. christineae Dumont, Reddy &Sanoamuang, 1996, have been recorded in Thailand. Whereas P. praedictus is common in occurrence, inhabiting roadside canals, ponds, swamps, lakes, reservoirs, rivers, and rice elds, P. christineae is less common, occurring in natural lakes and rivers (Sanoamuang, 1999).…”

“…To date the genus Phyllodiaptomus Kiefer, 1936, consists of eight valid species, distributed across central, southern, southeastern, and eastern Asia (Dumont & Reddy, 1993, 1994Reddy, 1994;Dumont et al, 1996). Among these, P. praedictus Reddy, 1994 andP.…”

An annotated checklist of the family Diaptomidae Sars, 1903 (Copepoda, Calanoida) in Vietnam

“…In Southeast Asia, this family has been studied well in Thailand (32 species) [16,27,34,35,37,40,41,42,43], and Indonesia (17 species) [1,7,8,18,21,22]. However, it is poorly known from Malaysia (10 species) [23,24,25,29], and Philippines (6 species) [8,28,36,60].…”
